Description

Technical Field

[0001] This description relates to a vent with a fastener and a compression limiter. The vent hole can be modular to be common or nearly common with other components of Dana. The vent hole includes a baffle to prevent liquid from leaving the outlet of the vent hole together with the gas. Background Art

[0002] A vehicle may include multiple housings. A vehicle may include a driveline with a transmission. The transmission may include a gearbox with multiple gears. The gearbox and other components within the vehicle enclosed space may use vents to discharge hot air or other fluids to relieve heat energy and pressure. The vent near the gearbox may be located near the axle housing. In addition, in addition to gas, fluids such as liquid may also be carried through the vent by the force that guides the gas through the vent section.

[0003] The complexity and quantity of vents in different embodiments may reduce the ability to interchangeably use vents in different components. For example, the first embodiment of the vent may not function the same as the second embodiment of the vent used for similar components on different vehicles. In addition, vents made of metal (such as steel) may increase the weight of the vehicle. In particular, steel may be brittle and may make the vent more prone to degradation. Similarly, the coupling between the vent and the component formed by using a sealant (such as a silicone sealant such as Hydrolomar) and / or using a press fit with a sealant may also be prone to degradation. Using steel, sealant, and / or press fit may make the vent prone to degradation. The degradation of the vent may cause further degradation of other components and / or impede vehicle functions, such as the vent getting stuck in the axle housing. Vents made of plastic or fiberglass can be used instead of metal to reduce the weight and brittleness of the vent. However, vents made of plastic or fiberglass can still be connected to components using sealants and press fit devices.

[0004] The air passing through the vent may carry liquid, either in the form of aerosol or larger droplets and bubbles. The liquid may include lubricating oil or other working fluids (such as engine oil) that come from the transmission or other components from which the vent can remove gas emissions. Similarly, the working fluid or other liquid conveyed through the vent may cause degradation of components outside the component ventilated by the vent. For example, lubricating oil (such as engine oil) may form a coating on the component and / or within the housing around the vent. The accumulation of such a coating may cause blockage, increased friction, or weakened electrical or thermal conductivity. The working fluid discharged from vehicle components (such as the transmission) through the vent may reduce the amount of working fluid available for processes such as lubrication and keeping the heat energy below the temperature threshold. Removing the working fluid from the component through the vent hole may increase the maintenance amount, such as cleaning the coated component from the working fluid or replenishing the working fluid to the component ventilated by the vent hole. Summary of the Invention

[0005] The inventors of the present text have recognized these and other problems existing in such systems. In one example, a mountable vent includes a first hollow portion with a sealing groove, a second hollow portion in fluid communication with the first hollow portion; an extension portion of the second hollow portion in fluid communication with the second hollow portion; a fastening portion for at least one fastener to fix the mountable vent to a housing, wherein the fastening portion extends radially from the first hollow portion or the second hollow portion and is located between the sealing groove and the extension portion; and a baffle located at the junction of the extension portion and the second hollow portion.

[0006] In this way, by connecting the vent to the assembly through the fastener and the fastening portion, the installation or removal of the vent is easier than the press-in type. The vent can be installed without using a sealant, such as hydrolomar, which needs to be applied and cured during installation and removed through a degradation process during removal to achieve the sealing and fluid coupling between the vent and the housing. The vent hole can be manually installed at any time during the manufacturing process and can be modular and universal for multiple components. The compression limiter can reduce the degradation of the vent material caused by excessive fastener torque or the compression force and / or other mechanical forces applied to the vent. If the vent hole degrades, it can prevent the vent hole from sliding out of the hole along the axis and can prevent the vent hole from contacting and degrading with the shaft.

[0007] In this way, the baffle can also prevent liquid from flowing out of the vent. The baffle can break the liquid film on the bubble or gas composed of liquid. Similarly, the baffle can also prevent other forms of liquid from flowing out of the vent hole through the extension portion. For example, the liquid may adhere and accumulate on the surface of the baffle. In this example, gravity and the adhesion force on the inner surface of the vent hole may pull the liquid broken by the baffle or accumulated on the baffle towards the housing where the vent hole ventilates.

[0008] It should be understood that the above summary is to introduce in a simplified form the concepts further described in the detailed description. It is not intended to identify the key or essential features of the claimed subject matter, the scope of which is uniquely determined by the claims following the detailed description. In addition, the claimed subject matter is not limited to the embodiments that solve any of the disadvantages pointed out in the above or any part of this disclosure.

[0026] This description relates to a vent that can be used to exhaust gases from a housing such as a gearbox and / or a transmission in a vehicle. The vent can be modular and universal, where the vent can be compatible with housings in a variety of configurations. The vent hole can be connected to the housing without using a sealant and / or a press fit, and the housing can be sealed through the vent hole using a removable seal (such as an O-ring). The vent can be made of plastic or fiberglass. The vent hole can have a first part and a second part that are hollow and fluidly connected. The first part and the second part can form a channel or multiple channels. The channel of the vent can extend into the housing interior and be fluidly connected to the housing interior. Fluids such as gases can leave the housing through the channel.

[0027] A baffle can be located at the mouth between the first part and the second part. The first part and the second part can be part of the same part of the vent, such as the second part. The baffle can extend at a non-zero angle (such as a 45-degree angle) relative to the centerline of the first part and / or the second part. In one example, the centerline of the first part and / or the second part can be the common centerline of the two parts. The side of the baffle can have an edge so that gases can flow around the baffle. The baffle can prevent the liquid carried by the gas passing through the first section of the channel from entering the second section. For example, the baffle can break bubbles, such as bubbles composed of a liquid or a liquid film on a gas. Such bubbles can be broken by the edge of the baffle. Another example is that the liquid may adhere to and / or accumulate on the surface of the baffle.

[0028] The vent has a fastening part. The fastening part can extend radially from the first and / or second part of the vent relative to the central axis. The fastening part can be connected to the housing surface forming the housing through a fastener (such as a bolt). However, it can be understood that the formation of the first and second holes can be non-limiting. The fastening part includes a compression limiter. The fastener can pass through the hole formed by the compression limiter and the auxiliary hole formed on the housing to form the housing. The fastener can be coupled to at least a complementary hole and / or a side of the hole formed by the compression limiter with a connectable interaction device, such as a thread. At least the complementary hole has a connectable interaction device complementary to the fastener, such as a thread. Similarly, the hole of the fastening part can also have a connectable interaction device complementary to the fastener. When connecting, the fastener can engage with the connectable interaction device. For example, the fastener can have a thread. When engaging with the connectable interaction device, the fastener can couple the fastening part and the vent to the housing.

[0029] The vent hole may have a groove. A detachable seal (such as an O-ring) can be arranged around the groove. The seal can at least prevent liquid (such as lubricating oil) from entering and also prevent the gas in the housing from escaping through channels other than the vent. The seal is detachable for seal replacement. The detachable seal and the fastening part can make the vent modular and suitable for chassis and housings around the chassis with various structures.

[0032] It should also be understood that the specific components and systems illustrated in the drawings and described in the following specification are exemplary embodiments of the utility model concept as defined herein. For ease of discussion, the drawings are collectively referred to. Thus, like elements are generally denoted by like reference numerals herein and will not be repeated. Figure 1 -2 shows a schematic diagram of an exemplary configuration of the relative positioning of the components. Among them, when the vehicle is on flat ground, the vertical position relative to gravity is shown. Figures 3 - 9 Shown approximately to scale, but other relative dimensions may also be used. As used herein, unless otherwise specified, the term "approximately" shall be understood to mean a range of plus or minus five percent.

[0033] In addition, Figures 1 - 9Shows an example configuration of the relative positioning of various components. If the components shown in the figure are in direct contact or directly coupled to each other, then in at least one example, these components can be referred to as being in direct contact or directly coupled respectively. Similarly, in at least one example, components shown as adjacent or contiguous to each other can be adjacent or contiguous to each other respectively. For example, components in face-to-face contact with each other can be referred to as face-to-face contact components. Another example is that in at least one example, components are placed separately from each other, with only space in between and no other components, and can be referred to as being placed separately from each other. Also, components shown above / below each other, on opposite sides of each other, or on the left / right side of each other relative to each other can be referred to as such components. Additionally, as shown in the figure, in at least one example, the topmost or point of a component can be referred to as the "top" of the component, and the bottommost or point of a component can be referred to as the "bottom" of the component. The top / bottom, upper / lower, above / below used in this article can be relative to the vertical axis in the figure and are used to describe the positioning of the elements in the figure relative to each other. Thus, in one example, an element shown above other elements is vertically positioned above the other elements. Another example is that the shapes of the elements depicted in the figure can be referred to as having these shapes (e.g., circular, linear, planar, curved, round, chamfered, beveled, or similar shapes). Additionally, in at least one example, elements shown intersecting each other can be referred to as intersecting elements or intersecting each other. Furthermore, in one example, an element shown inside or outside another component can be referred to as such a component. Additionally, when describing each component, it can be related to the reference axis in the accompanying drawing.

[0034] See Figure 1 , in which an example vehicle 5 is shown. The vehicle 5 can have a front end 100 and a rear end 102 and can be divided into two substantially symmetric halves by a longitudinal axis 104.

[0035] In some examples, the vehicle 5 can be a hybrid vehicle, and one or more wheels 55 can receive multiple torque sources. Alternatively, the vehicle 5 can include only an internal combustion engine. In other examples, the vehicle 5 can be a fully electric vehicle, powered entirely by an energy storage device such as a battery 58.

[0036] In the example shown, the vehicle 5 includes a prime mover 52. In one example, the prime mover 52 can be an engine, such as an internal combustion engine. In this example, the prime mover 52 can receive a fuel such as gasoline or diesel for combustion and convert the chemical energy in the fuel into rotational energy.

[0037] In other examples, the prime mover 52 can be an electric machine, which can be an electric motor, an electric motor / generator, or an electric motor / engine. The prime mover 52 can receive electrical energy from the battery 58, and the electrical energy is converted into rotational energy, such as torque, at the transmission 56. The transmission 56 can be a planetary transmission, in which at least one sun gear in the gear set is surrounded and engaged by a plurality of planetary gears. The torque can be transmitted to the wheels 55, which include a set of front wheels near the front end 100 of the vehicle 5 and a set of rear wheels near the rear end 102 of the vehicle 5. The prime mover 52 can also operate as a generator, for example, to provide electrical power during a braking operation to charge the battery 58.

[0038] Figure 1 An embodiment is shown in which the prime mover 52 provides rotational energy to the wheels 55 of the vehicle 5 through the transmission 56. The wheels 55 can be transmission-connected to the vehicle 5 or the transmission through the first axle 62 and the second axle 64. In this example, in the embodiment of the vehicle 5, the first axle 62 is near the front end 100 of the vehicle 5, and the second axle 64 is near the rear end 102 of the vehicle 5. In this example, in the embodiment of the vehicle 5, the prime mover 52 and the transmission 56 are near the front end 100 of the vehicle 5. The gearbox 70 is installed in the transmission, providing different gear selection options for the transmission through the clutch. In this example, the prime mover 52 and the transmission 56 can provide rotational energy to the drive shaft 72, transmitting the rotational energy to the differential 68 to rotate the wheels 55 closest to the rear of the vehicle 102. It can be understood that in other examples, rotational energy can also be provided to the wheels 55 near the front end 100 of the vehicle 5. In addition, in other examples, each of the wheels 55 near the front end 100 and the wheels 55 near the rear end 102 can be connected to a separate transmission, for example, when the vehicle 5 is configured for all-wheel drive. In addition, in other embodiments, the transmission 56 and / or the prime mover 52 can be arranged at a position closer to the rear end 102 of the vehicle 5 than the front end 100.

[0039] The battery 58 can be located between the wheels 55, closer to the rear end 102 of the vehicle 5 than the front end 100. For example, the battery 58 can be installed under the rear passenger seat of the vehicle. In another example, the battery 58 can be located in the floor of the rear compartment of the vehicle or integrated into the vehicle chassis. However, in other examples, the relative position of the battery 58 in the vehicle 5 may be different from that Figure 1 shown.

[0040] Figure 2AFigure 200 shows a schematic diagram of a transmission 56 and a gearbox 70 with a vent 202. Above the transmission 56 is a first axle 62. The first axle 62 can be drivingly connected to the transmission 56. The vent 202 can pass through a first hole 204 in the housing 205 of the gearbox 56 and a second hole 206 in the housing 207 of the gearbox 70. A gear assembly 208 can be located in a housing 210 formed by the gearbox 70. In Figure 2A the example, the housing 207 can serve as the housing of the housing 210. In Figure 2A the example, the housing 205 of the gearbox 56 can serve as an additional housing surrounding the housing 210 and the gearbox 70. The vent 202 can be in fluid connection with the housing 210. The vent 202 can be connected to the housing 207 by means of mounting or the like. However, it can be understood that the position and formation of the housing may not be restricted. The vent 202 can be used for other housings, such as housings formed by an engine housing, a fuel tank, an emission treatment device, or a battery housing.

[0041] The gear assembly 208 can be located around an axle 212, for example surrounding the axle 212 and being drivingly connected to the axle 212. The axle 212 can drivingly connect the gear assembly 208 to a prime mover 52. For example, the axle 212 can be an output axle of the prime mover 52.

[0042] The vent 202 can be centered and aligned with an axis 218, where the vent 202 can be located around the axis 218. The axis 218 can be vertical, where the axis 218 is generally parallel to the direction of gravity 220. The axle 212 can be centered and aligned with an axis 221, where the axle 212 can be positioned around the axis 221, where the axle 212 can circumferentially surround the axis 221 and have a length consistent with the axis 221. The axis 221 can be longitudinal with respect to the transmission 56, the gearbox 70, and the vehicle 5, where the axis 221 is generally perpendicular to the direction of gravity 220.

[0043] Unless otherwise specified, features described as axial may be approximately parallel to the axis. Unless otherwise specified, features described as transverse may be approximately perpendicular to the axis. The central axis 221 is longitudinal with respect to the gear assembly 208, the gearbox 70, and the gearbox 56 and can serve as a longitudinal axis. Features described as longitudinal with respect to a longitudinal axis, such as the central axis 221, can be approximately parallel to the longitudinal axis. Features surrounding or extending from a longitudinal axis can be described as radial features.

[0044] The housing 210 can form a chassis 217 filled with lubricating oil 216 (such as engine oil). The oil sump 217 and the lubricant 216 can be located below the gear assembly 208 relative to the shaft 218. The lubricant 216 can lubricate the gears, shafts, clutches, and other mechanical components of the gear assembly 208. Lubrication can reduce friction and lower the temperature of the gear assembly 208. During operation, gases 214 (such as exhaust gases) may accumulate in the housing 210 above and around the gear assembly 208. During operation, the thermal energy accumulated in the gases 214 may increase the temperature and exert pressure on the housing 210 and the gearbox 70. The vent 202 can reduce the temperature and pressure of the housing 210 by discharging the gases 214.

[0045] The vent 202 can be composed of a first part 222 and a second part 224. The first and second parts 222, 224 are hollow and can form a passage 226. The first and second parts 222, 224 can serve as the first hollow part and the second hollow part respectively. The shaft 218 can serve as the single, straight, and central axis of the first part 222 and the passage 226. The passage 226 can be fluidly coupled and in fluid communication with the housing 210.

[0046] The extension part 228 and the fastening part 230 of the second part 224 can extend radially from the vent 202 relative to the shaft 218. The extension part 228 is a conduit that the second part 224 can form and is fluidly connected to the passage 226. The extension part 228 of the second part 224 can serve as the third hollow part of the vent 202 and is in fluid communication with the first and second parts 222, 224. The extension part 228 can extend radially and vertically relative to the shaft 218 and the passage 226. As an embodiment, the fastening part 230 can extend and be formed from the first part 222. However, it can be understood that in other embodiments, the fastening part 230 can extend and be formed from the second part 224.

[0047] The vent 202 can be installed on the outer surface of the gearbox housing 207 through the fastening portion 230 and the fastener 236. The vent 202 can be a mountable vent. The fastening portion 230 can include a flat extension portion or be a flat extension portion. The fastening portion 230 can include a compression limiter 234 around the third hole 232. The compression limiter 234 can be formed of a material (such as metal) that is harder and stronger than the material of the vent 202. The compression limiter 234 can be formed and molded in the material of the fastening portion 230. The compression limiter 234 can be molded in the flat extension portion of the fastening portion 230. The compression limiter 234 can be in contact with the outer surface of the housing. For the schematic diagram 200, the compression limiter 234 can be in contact with the outer surface of the gearbox housing 207. For the schematic diagram 200, relative to the gravity 220, the compression limiter 234 can be closely attached to the upper surface of the gearbox housing 207. The inner surface of the housing can be in contact with the compression limiter 234. For the schematic diagram 200, the inner surface of the gearbox housing 205 can be in contact with the compression limiter 234. For the schematic diagram 200, relative to the gravity 220, the inner surface of the transmission housing 205 can be located above the compression limiter 234.

[0048] In the example shown in the schematic diagram 200, the fastening portion 230 and the compression limiter 234 can be located above and in contact with the surface of the gearbox 70, where the fastening portion 230 can be located above the fourth hole 242. The fastening portion 230 and the compression limiter 234 can share contact with the surface of the gearbox 70. The fastening portion 230 can be aligned with the gearbox 70 such that the central axis 231 can be substantially concentric with the third hole 232 and the fourth hole 242 and be circumferentially surrounded by the third hole 232 and the fourth hole 242.

[0049] At least one fastener (such as the fastener 236) can be used to fix the vent 202 to the housing (such as the gearbox housing 207) through the fastening portion 230. In one embodiment, the fastener 236 (such as a bolt) can be inserted through the fastening portion 230 and the fourth hole 242 to fix the fastening portion 230 to the gearbox housing 207. The fastener 236 can pass through the fastening portion 230 and a hole similar to the fourth hole 242 to fix the fastening portion 230 to another housing. The third hole 232 and the fourth hole 242 can respectively have a first surface 235 and a second surface 243. The first surface 235 and the second surface 243 can be located within the diameter of their respective holes, where the first surface 235 can be referred to herein as the first inner surface 235 and the second surface 243 can be referred to herein as the second inner surface 243. Both the first inner surface 235 and the second inner surface 243 can be cylindrical and surround the central axis 231. The fastener 236 can be in coplanar contact with the first inner surface 235 and / or the second inner surface 243.

[0050] The first part 222 may have a groove 238. A sealing member 240 may be disposed around the groove 238. The sealing member 240 may interface with the surface of the second hole 206. The gas 214 may be discharged from the housing 210 through the passage 226 of the vent 202. The gas 214 in the housing 210 may enter the vent 202 through the inlet 244 on the first part 222. The gas 214 may flow out of the vent 202 through the outlet 246 on the extension part 228. The gas 214 may flow out of the casing 210 along the path 250.

[0051] The first part 222 and the hole 206 may extend through the wall 254 into the housing 210. The wall 254 may be the housing wall of the gearbox housing 207 and may provide a surface to which the fastener 236 and the fastening part 230 may be coupled. The fourth hole 242 may extend partially through the housing wall 254. The wall 254 may have a thickness 256. The wall thickness 256 may be referred to herein as the housing wall thickness 256. For the schematic diagram 200, the housing wall 254 may form the top of the housing 207, and its surface is perpendicular to the gravity 220. However, it can be understood that the position of the housing wall 254 may not be restricted. For example, the housing wall 254 may form the bottom wall, and its surface is perpendicular to the gravity 220. Another example is that the housing wall 254 may form a side wall or another component whose surface is parallel to the gravity.

[0052] The second hole 206 may have a length approximately the same as the thickness 256, where the length refers to the distance along the central axis relative to the fourth hole 242. The fourth hole 242 may have a length less than the thickness 256, where the length is the distance along the central axis relative to the fourth hole 242.

[0053] To install the vent 202 into the housing, the first part 222 may be passed through a hole. This hole is the receiving port for the first part 222. Through this hole, the first part 222 may enter the housing and be in fluid connection with the housing. The fastening part 230 may also be fixed to the housing through the surface and the fastener. The vent 202 may be fixed at least to the housing of the housing. The vent 202 may be installed by hand at any position during the assembly of the housing and the casing.

[0054] In the example in the schematic diagram 200, the hole and the receiving port may be the second hole 206, the housing may be the gearbox housing 207, and the housing may be the housing 210. For the example shown in the schematic diagram 200, the vent 202 may be installed by passing the first part through the first and second holes 204, 206, and a part of the second part 224 may pass through the first hole 204. The second hole 206 may be located inside the housing of the housing, such as the gearbox housing 207 of the housing 210. The first hole 204 is located in the second housing, such as the transmission housing 205.

[0055] However, it is understood that in other embodiments, the chassis may have only one housing. For example, there may be an embodiment of a housing enclosed by a single housing. In this example, the first portion 222 may pass through and extend through a first hole in the housing, and the second portion 224 may extend above the housing.

[0056] It is also understood that there may be multiple housings around the housing. For example, there may be a housing enclosed by multiple housings. In this example, the first portion 222 may pass through holes in each of the housings surrounding the housing, each of which has an inner housing and an outer housing, where the inner housing is closest to the housing and the outer housing is farthest from the housing. The first portion 222 may extend through multiple holes in the multiple housings surrounding the housing. The first portion 222 may pass through a hole in the innermost housing. The second portion 224 may pass through and extend through multiple holes in the multiple housings surrounding the housing. The second portion 224 may pass through and / or extend above the outermost housing. The second portion 224 may be fluidly coupled to another fluid-carrying component, where the fluid-carrying component may be a sealed fluid seal such as a vent, duct, hose, flue, pipe, reservoir, or another housing, and may pass through and extend above the outermost housing.

[0057] The compression limiter 234 may transfer compression forces and other mechanical forces from the transmission 56 to the gearbox 70 and away from the material of the vent 202. The compression limiter 234 may also provide compression resistance to the fastener 236 and transfer compression forces and other mechanical forces from the fastener 236 to the gearbox 70. For example, the fastener 236 may have a head 262. The head 262 may abut and share a contact surface with the exposed surface 264 of the compression limiter 234.

[0058] The compression limiter 234 can prevent the vent 202 from degrading due to excessive torque on the fastener 236. The fastener 236 can pass through the third hole 232 and the fourth hole 242. The fastener 236 can have a connectable interaction device complementary to the connectable interaction device on at least the fourth hole 242, such as threads. The fastener 236 can also have a connectable interaction device complementary to the connectable interaction device on the third hole 232. The connectable interaction device can be formed by and / or located on the first inner surface 235 and surround the third hole 232. The connectable interaction device is formed by and / or located on the second inner surface 243 and surrounds the fourth hole 242. When components and / or features are coupled through the connectable interaction device, the components and / or features can be referred to as threads herein. When the fastener 236 is threadedly connected to the fourth hole 242 and at least passes through the fourth hole 242 and extends through the third hole 232, the fastening portion 230 and the vent 202 can be fastened and / or coupled to the gearbox 70. When threadedly connected to the third hole 232 and the fourth hole 242 and passing through the third hole 232 and the fourth hole 242, the fastener 236 can fix and / or couple the fastening portion 230 and the vent 202 to the gearbox 70. When fastened and / or coupled to the third hole 232 and / or the fourth hole 242, the fastener 236 can share surface contact with the features of the third hole 232 and / or the fourth hole 242, such as the first inner surface 235 and the second inner surface 243. The installation and coupling of the fastening portion 230 can be completed by applying a final torque to the fastener 236. Coupling the fastening portion 230 to the gearbox housing 207 can mount the vent 202 to the gearbox 70. The fastening portion 230 can be fastened by the fastener 236 to a hole that is approximately the same size or similar in size and connectable interactively with the fourth hole 242. The vent 202 can be mounted on a housing having a hole that is approximately the same size or similar in size and connectable interactively with the fourth hole 242 through the fastening portion 230 and the fastener 236.

[0059] The head 262 can apply a compressive force to the exposed surface 264. The connectable interaction device of the fastener 236 can apply a compressive force to the complementary connectable interaction device of the first and / or second inner surfaces 235, 243. The compressive force of the head 262 of the fastener 236 and the complementary connectable interaction device can be referred to as the compressive force 266 alone or together. The compressive force 266 can extend to the gearbox housing 207 through the material of the compression limiter 234. The compressive force 266 can be greater than the gravitational force 220. When the direction of the gravitational force 220 is opposite to the compressive force 266, the fastener 236 can connect the fastening portion 230 and the vent 202 to the gearbox housing 207. When the direction of the gravitational force 220 is opposite to the compressive force 266, the fastener 236 can connect the fastening portion 230 and the vent 202 to another housing compatible with the fastener 236 and the fastening portion 230.

[0060] The fastening portion 230 and the fastener 236 can prevent the vent 202 from detaching from the gearbox housing 207 when the sealing member 240 ages. For example, if the components and features of the vent 302 degrade, the fastening portion 230 and the fastener 236 can prevent the vent 202 from detaching from the gearbox housing 207. When the fastening portion 230 and the vent 202 are connected to the gearbox 70, the vent 202 or parts of the vent 202 can be prevented from colliding with the housing 260 of the first axle 62 or other features. Additionally, referring to Figure 1 , when the fastening portion 230 and the vent 202 are connected to the gearbox 70, the vent 202 can be prevented from colliding with the components and / or features of the second axle 64. Additionally, referring to Figure 1 , when the fastening portion 230 and the vent 202 are connected to the gearbox 70, the vent 202 can be prevented from colliding with the components and / or features of the drive train, such as the drive shaft 72 or the differential 68. In this or other examples, if the vent 202 is made of plastic, fiberglass, and / or other non-metallic materials, deformation due to brittleness can be prevented. In these examples, the vent hole 202 can be prevented from separating into several parts or degrading. In reference Figure 1 of these examples, the components of the vent 202 or the parts of the vent 202 can be prevented from colliding with the components and / or features of the first axle 62, the second axle 64, the differential 68, and / or the drive shaft 72.

[0061] The sealing member 240 (such as an O-ring) can be separated from the vent 202 and can be removed from the groove 238. The sealing member 240 can be removed from the groove 238 without causing degradation of the sealing member 240 or the vent 202. The seal 240 can be an elastic ring. The elasticity of the seal 240 allows the seal 240 to be compressed so that the first portion 222 can axially pass through the second hole 206 under intentional force. The elasticity of the seal 240 can cause the seal 240 to expand, contact the surface of the second hole 206, and form a seal.

[0062] The seal formed by the sealing member 240 can be at least liquid-tight or air-tight. The sealing member 240 can prevent the lubricant 216 from flowing out of the housing 210. The seal formed by the sealing member 240 can prevent the gas 214 from escaping from the housing 210 without passing through the passage 226 of the vent 202.

[0063] In Figure 2AIn the example, the gas 214 traveling along the path 250 can enter the first part 222 of the housing 210 through the inlet 244. After entering the first part 222, the gas can pass axially through the channel 226 relative to the axis 218. Along the path 250, the gas 214 can flow out of the gearbox 70 from the part of the channel 226 surrounded by the first part 222. Along the path 250, the gas 214 can flow out of the transmission 56 from the part of the channel 226 surrounded by the second part 224. At the mouth 248 of the extension 228, the path 250 can change direction. Above the mouth 248 is the end 252 of the second part 224. The end 252 can be closed to prevent the gas in the channel 226 from moving along the axis 218. The gas 214 on the path 250 can flow out of the channel 226, enter the extension 228 through the mouth 248, where the path 250 can change from axial to radial relative to the axis 218. The gas on the path 250 can leave the extension 228 and the vent 202 through the outlet 246. For example, the gas can leave the outlet 246 and enter the area around the vehicle 5. As another example, the outlet 246 can be in fluid connection and fluid communication with another fluid-tight body, such as a vent, a pipe, a hose, a flue, a duct, a reservoir, or a housing. In this example, these other mechanisms can be used to exhaust, store, or process the gas 214.

[0064] Go to Figure 2B , which shows Figure 2A the area 270 isolated from other components and the view 280 of the enclosed component in Figure 2B And the view 280 also shows liquid bubbles, such as the bubble 282. The bubble 282 and other liquid bubbles can pass through the vent 202 along with the gas (such as the gas 214) along the path 250. For example, the bubble 282 can consist of a thin film between the liquid and the gas (such as the lubricant 216 and the gas 214). As another example, the bubble 282 can be composed mostly of liquid, such as the lubricant 216. The gas flow through the exhaust pipe may be large enough that the bubble 282 passes through the first and second parts 222, 224 of the vent 202 under the action of gravity 220.

[0065] Figure 2CShows view 280 and what may occur when bubble 282 or other liquid bubbles come into contact with baffle 272. Baffle 272 may disrupt the surface tension of bubble 282, resulting in rupture 284. Fracture 284 can separate bubble 282 into smaller droplets, such as droplet 290. The droplets (such as droplet 290) in bubble 282 generated by fracture 284 can adhere to the first surface 286 of baffle 272. The first surface 286 can face channel 226. The first surface can be continuous with one or more of the multiple surfaces 288 of channel 226. Similarly, the droplets of bubble 282 (such as droplet 290) generated by fracture 284 can adhere to one or more of the multiple surfaces 288 of vent 202. After adhering to the surface, droplet 290 or other droplets generated by rupture 284 may be pulled by gravity in the direction of gravity 220. Droplet 290 or other droplets generated by fracture 284 can slide or move along the direction of gravity 220 towards housing 210. Alternatively, droplet 290 and / or other droplets can accumulate and adhere to the first surface 286. The adhesive force on surface 286 may prevent droplet 290 from being carried by the airflow on path 250 through the vent. Gravity can drag droplet 290 in the direction of gravity 220.

[0066] Gas can flow around baffle 272 along path 250. For example, path 250 can be divided into multiple sub-paths around baffle 272, such as first sub-path 292 and second sub-path 294. First sub-path 292 and second sub-path 294 can be represented by dashed lines. First sub-path 292 can pass through one or more edges 298 on the side of baffle 272. Second sub-path 294 can pass through the edge 296 at the top of baffle 272.

[0067] Figures 3 - 9 A set of reference axes 301 is provided for comparison between the views shown. Reference axes 301 represent the y-axis, x-axis, and z-axis. In one example, the Z-axis can be parallel to the direction of gravity, and the X-Y plane can be parallel to the horizontal plane where vent 302 is located. When referring to the reference direction, the positive direction can refer to the arrow directions of the y-axis, x-axis, and z-axis, and the negative direction can refer to the opposite directions of the arrows of the y-axis, x-axis, and z-axis. Filled circles can represent the arrows and axes facing the view or the front view. Unfilled circles can represent the arrows and axes facing away from the view, or in other words, facing the negative direction of the view.

[0068] Figure 3 Shows a first perspective view 300 of vent 302. Vent 302 can be an embodiment of vent 202 with reference to Figures 2A - 2C

[0069] The dividing surface 316 divides the vent 302 into a first part 322 and a second part 324, where the second part 324 is located above the first part 322. The vent 302 can be aligned with the first axis 318 such that the features of the first and second parts 322, 324 extend along and are positioned around the first axis 318. The second axis 320 can extend radially relative to the first axis 318. The extension 328 of the second part 324 can extend along and be positioned around the second axis 320. The extension 328 is hollow and can be referred to herein as the hollow extension 328. Refer to Figure 2A , the first part 322 and the second part 324 can be the same as or similar to the first part 222 and the second part 224 respectively. Refer to Figures 2A - 2C The first axis 318 can be the same as or similar to the axis 218.

[0070] The first part 322 and the second part 324 can be coupled on the dividing surface 316. The dividing surface 316 can be formed on a line generally parallel to the x-axis and the y-axis. The fastening portion 330 can extend radially from the vent 302 relative to the first axis 318. The fastening portion 330 can be or include a flat extension having a single or multiple surfaces parallel to the dividing plane 316, such as the surface 349. For example, the dividing surface 316 shown in the perspective view 300 can be located below the fastening portion 330. In this example, the fastening portion 330 can be formed by extending from the second part 324. The first part 322 can be located below the fastening portion 330.

[0071] Another example is that the dividing surface 316 can be located above the fastening portion 330. In this example, the fastening portion 330 can be formed by extending from the first part 322. The second part 324 can be located above the fastening portion 330.

[0072] The second part 324 can be composed of a second conduit 326 and an extension 328. Refer to Figure 2A , the extension 328 can be the same as or similar to the extension 228. The second conduit 326 and the extension 328 can be hollow and fluidly connected to each other. The second conduit 326 can be positioned around the first axis 318. The second conduit 326 can circumferentially surround the first axis 318. The extension 328 can be arranged around the second axis 320. The extension 328 can surround the second axis 320. The extension 328 extends radially and perpendicularly relative to the first axis 318. The second conduit 326 and the extension 328 can have approximately cylindrical portions.

[0073] The first part 322 may be constituted by a first conduit 332. The first conduit 332 may be disposed around a first axis 318. The first conduit 332 may circumferentially surround the first axis 318. A groove 338 may be located around the first conduit 332 and below the fastening portion 330. One side of the groove 338 may be a fastening portion, such as the fastening portion 330; the other side of the groove 338 may be a land, such as the first land 342. For the embodiment shown in the vent 302, above the groove 338 may be a first column 340, which is part of the fastening portion 330. Below the groove 338 may be the first land 342. The first column 340 and the first base 342 may be positioned around the first axis 318. The first column 340 and the first base 342 may surround the first axis 318. The first conduit 332 may have an approximately cylindrical portion.

[0074] The compression limiter 334 may be surrounded and partially enclosed by the material of the fastening portion 330. The compression limiter 334 may surround and partially enclose a third axis 335 that is approximately parallel to the first axis 318. The third axis 335 may be the same as or similar to the central axis 231. The compression limiter 334 may be formed around and located around a hole 336 in the fastening portion 330. A second strut 344 surrounds and partially encloses the compression limiter 334. The first strut 340 and the second strut 344 may be cylindrical, serving as the first cylinder and the second cylinder respectively, for supporting and forming the fastening portion 330. The first strut 340 may support the fastening portion and connect it to the first and second parts 322, 324 of the vent. The second strut 344 may support the compression limiter 334. The second column 344 may be connected to the first column 340 to form the fastening portion 330. The first and second columns 340, 344 may be connected by a first platform 346 and a second platform 348. The first platform 346 and the second platform 348 may be semi-rectangular in shape. The first platform 346 and the second platform 348 may conform to the circumferences of the first and second columns 340 and 344 and have regions that curve and connect around the circumferences of the first and second columns 340 and 344.

[0075] There may be a volume 350 between the first platform 346 and the second platform 348. As can be seen from the perspective view 300, the volume 350 is a groove in the fastening portion 330 that is located between the first platform 346 and the second platform 348 and between the first column 340 and the second column 344. The volume 350 may be formed by a groove surrounded by multiple parts including the first platform 346, the second platform 348, the first column 340, and the second column 344. The first platform 346 may be located above the volume 350, and the second platform 348 may be located below the volume 350. The first and second platforms 346, 348 may be connected by the material of the fastening portion 330 (e.g., Figure 8BThe ribs 820) are vertically connected and supported relative to the first axis 318. The volume 350 can be divided by the second axis 320 into volumes that are symmetric on the first and second sides (e.g., the first volume 350a and the second volume 350b). The first platform 346 can have an upward-facing surface 349. The surface 349 may not be surrounded by or face the volume 350 and can thus be referred to as the first outer surface 349. The volume 350 can reduce the weight of the vent 302 and the materials used to manufacture the vent 302.

[0076] The compression limiter 334 forms a surface 337 around the third axis 335 and the hole 336. The surface 337 is formed on the circumference of the hole 336 and the inner circumference of the compression limiter 334, and the surface 337 can be referred to as the inner surface 337. Referring Figure 2A to, the compression limiter 334 and the hole 336 can be embodiments of the compression limiter 234 and the third hole 232, respectively, and their functions are the same as or similar to those of the compression limiter 234 and the third hole 232. The inner surface 337 can be the first inner surface 235 of the third hole 232. Fasteners, such as Figure 2A the fastener 236 in, can be inserted through the hole 336 into a complementary hole, which can be Figure 2A an embodiment of the fourth hole 242 in, and can also have the same or similar function as Figure 2A the fourth hole 242 in. The fastener can be used to couple the compression limiter 334, the fastening portion 330, and the vent 302 to the surface of the housing, which has a hole complementary to the fastener 236. Connectable interaction means, such as threads, can be connected to or formed on the inner surface 337. The connectable interaction means on the inner surface 337 can be complementary to the connectable interaction means formed or coupled on the surface of the fastener.

[0077] The top 352 of the second conduit 326 can be a closed surface. The bottom of the first conduit 332 can have an inlet 354. The extension 328 has an outlet 356. The port 358 can be formed by the extension 328 and is located around the outlet 356. The port 358 can be used to fluidly couple the extension 328 and the vent 302 to the port or fitting of another sealed fluid body, such as a vent, a pipe, a hose, a flue, a duct, a reservoir, or a housing. The port can consist of multiple bottom surfaces. In one embodiment, there can be a first land 360a and a second land 360b. The first land 360a and the second land 360b can form a first shape 361a and a second shape 361b, respectively. The first shape 361a and the second shape 361b can be semi-conical, with their diameters gradually decreasing relative to the second axis 320 near the outlet 356.

[0078] The functions of the top 352, the inlet 354, and the outlet 356 can be respectively the same asFigure 2A The end 252, the inlet 244, and the outlet 246 therein are the same or similar.

[0079] Go to Figure 4 , which shows a first side view 400 of the vent 302. In the example of Figure 4 , the second axis 320 and the x-axis are positive axes and extend into the first side view 400. The vent 302 can be bisected by a line 406, which can be referred to herein as line A 406. Line A 406 can be substantially parallel to the first axis 318. Line A 406 and the line parallel to the Z-axis can form a plane that divides the vent 302 into symmetric halves. A cross-section (such as the first cross-sectional view 600 in Figure 6 ) can be taken on line A 406. The vent 302 can have a height 410 that is substantially parallel to line 406 and the first axis 318. The height 410 extends axially with respect to the first axis 318, from the inlet 354 to the top 352.

[0080] The port 358 can surround the second axis 320, the outlet 356, and the extension 328. The outlet 356 and the extension 328 can surround and form an approximately cylindrical inner surface 420. From the perspective of the first side view 400, the inner surface 420 can be approximately circular.

[0081] The inner surface 420 can be located around the baffle 430. The baffle 430 can extend from the inner surface 420 and be continuous with the inner surface 420. The baffle 430 can extend from the lowest point of the inner surface 420 toward the second axis 320.

[0082] Go to Figure 5 , which shows a second side view 500 of the vent 302. The second side view 500 shows that the fastening portion 330 can be divided by a line 504, which is referred to herein as line C 504. The second side view 500 also shows that the extension 328 and the second conduit 326 can be divided by a line 505 (referred to herein as line G 505). A cross-sectional view (cross-sectional view 818) can be taken on line C 504 in Figure 8B . Figure 12 A cross-sectional view (cross-sectional view 1200) of

[0083] In this example, the first part 322 has a first height 506, the second part 324 has a second height 508, and the fastening part 330 has a third height 510. The first height 506, the second height 508, and the third height 510 are substantially parallel to the first axis 318. Additionally, for example, the first height 506, the second height 508, and the third height 510 can be perpendicular to and substantially parallel to the Z-axis. The first height 506 extends the distance of the first part 322 from the inlet 354 to the dividing plane 316. The second height 508 is the distance of the second part 324 from the dividing plane 316 to the top 352. The third height 510 extends from the surface 530 of the second platform 348 to the first outer surface 349 and then to the second platform 348. The surface 530 can face downward. The surface 349 can be unenclosed or face the volume 350, which can be referred to as the second outer surface 530. In Figure 3 the example of Figure 3 , the fastening part 330 extends radially from the second part 324, and the second height 508 includes the third height 510. For other examples where the fastening part 330 extends radially from the first part 322, the first height 506 can include the third height 510.

[0084] The first column 340 and the first base 342 can share a first outer diameter 512. The cylindrical portion of the first conduit 332 can have a second outer diameter 514 that is smaller than the first outer diameter 512. The cylindrical portion of the second conduit 326 can have a third outer diameter 518. In one embodiment of the vent 302, the third outer diameter 518 can be less than the second outer diameter 514.

[0085] The extension portion 328 can have a fourth outer diameter 522. The extension portion 328, the outlet 356, and the notch 528 can share the fourth outer diameter 522. The notch 528 can be located between the first land 361a and the second land 360b. The first and second lands 360a, 360b can have a fifth outer diameter 524. The fifth outer diameter 524 can be greater than the fourth outer diameter 522. The diameter of the first shape 361a can decrease from the fifth outer diameter 524 to the distance of the fourth outer diameter 522 between the first land 360a and the notch 528. The diameter of the second shape 361b can decrease from the fifth outer diameter 524 to the distance of the fourth outer diameter 522 between the second pad 360b and the outlet 356. The length of the extension portion 328 is 532. The length 532 extends axially from the third outer diameter 518 to the outlet 356 of the extension portion 328 with respect to the second axis 320.

[0086] Figure 5An offset 555 is also shown below the bottom surface of the bottom platform relative to one end of the seal groove. For the embodiment of the vent 302, the offset 555 can extend from the top of the groove 338 and the bottom of the first upright 340 to the bottom surface of the second platform 348. The first platform 346 and the second platform 348 are separated from the seal by at least the offset 555. The offset 555 can completely separate the first platform 346 and the second platform 348 from the seal.

[0087] Figure 6 A first cross-sectional view 600 of the vent 302 is shown. The view 600 is taken with reference to Figure 4 on line A406. The first cross-sectional view 600 shows the features inside the vent 302, such as the inner diameter, channels, and surfaces. The first cross-sectional view 600 shows an area 606, which can be referred to as area B 606 here. The first cross-sectional view 600 also shows an area 607, which can be referred to as area F 607 here. Area B 606 can be enclosed by a box formed by multiple dashed lines. Area F 607 can be surrounded by a box formed by multiple dashed lines respectively. The first and second parts 322, 324 can form a first channel 604 of the vent 302. The second channel 610 can be formed and enclosed by the extension part 328. The total channel through the vent 302 can include the first channel 604 and the second channel 610, where the first channel 604 is the first part of the above total channel and the second channel 610 is the second part. The first channel 604 and the second channel 610 can be fluidly coupled and communicate fluidly at the orifice 608. The orifice 608 can be the junction between the first channel 604 and the second channel 610, and is also the junction between the extension part 328 and the second part 324. The first channel 604 can be fluidly coupled and communicate fluidly with the inlet 354. The second channel 610 can be fluidly connected and in fluid communication with the outlet 356. Area B 606 encloses the groove 338 and the first base 342. Similarly, area B 606 encloses a part of the second upright 344 and a part of the first channel 604 extending through the vent 302. The first channel 604 can be the same as or similar to Figure 2A the channel 226 in Figure 2A and its function can also be the same as or similar to Figure 2A the channel 226 in

[0088] The first portion 604a may have a surface 642 about a first axis 318, herein referred to as a fourth inner surface 642. Similarly, the second portion 604b may have a surface 644 about the first axis 318, herein referred to as a fifth inner surface 644. The fourth inner surface 642 and the fifth inner surface 644 may be curved. In one embodiment, the fifth inner surface 644 may be located radially of the first axis 318 and curve about the first axis 318. In this embodiment, portions of the fifth inner surface 644 may curve radially about the first axis. The upper portion 646 of the fifth inner surface 644 may be radial with respect to the first axis 318.

[0089] For example, in an embodiment of the vent 302, the first passage 604 may axially extend along the first axis 318 from the inlet 354 to a first surface 616 of the top 352. The first surface 616 may be surrounded by the vent 302, herein referred to as a first inner surface 616. In this example, the second passage 610 may axially extend from the orifice 608 to the outlet 356 with respect to a second axis 320. The height of the first portion 604a may be substantially the same as the first height 506. In this example, the second portion 604b may have a fourth height 612. The fourth height 612 may axially extend with respect to the first axis 318 from the dividing surface 316 to the first inner surface 616. The top 352 has a thickness 614, where the thickness 614 is substantially parallel to the first axis 318. The fourth height 612 is substantially equivalent to the distance of the thickness 614 minus the second height 508.

[0090] The top 352 may have a step 618 between the first surface 616 and the orifice 608. Similarly, the step 618 may also be located between the upper portion 646 and the orifice 608. The step 618 may have a second surface 620 and a third surface 621. The second surface 620 and the third surface may herein be referred to as a second inner surface 620 and a third inner surface 621, respectively. The second inner surface 620 may extend from the second passage 610 and have the curvature of the second passage 610. The second inner surface 620 may be continuous with the inner surface 420 of the extension 328. The third inner surface 621 may be connected to the first inner surface 616. The third inner surface 621 may be connected to the first inner surface 616 and the upper portion 646.

[0091] The first and second conduits 332, 326 have a first inner diameter 622. Similarly, the inner diameter 622 is close to the diameter of the passage 604. The extension portion 328 has a second inner diameter 626. The first inner diameter 622 is connected to the height 410 of the vent 302, and the second inner diameter 626 is connected to the length 532 of the extension portion 328.

[0092] The first cross-sectional view 600 shows that the compression limiter 334 can have a sixth outer diameter 630 and a third inner diameter 624. The first cross-sectional view 600 also shows that the compression limiter 334 can have a height 628, which can be relatively large and extend above the third height 510 of the fastening portion 330. The compression limiter also shows a base 632. The base 632 can extend radially from the sixth outer diameter 630 of the compression limiter 334 into the material of the fastening portion 330 relative to the third axis 335. The base 632 can serve as an anti-pull function to prevent the compression limiter 334 from sliding or undergoing other movements along the third axis 335.

[0093] At the orifice 608, the baffle 430 can extend between the first channel 604 and the second channel 610. The baffle 430 can be Figures 2A - 2B the baffle 272 in. The baffle 430 can block liquid bubbles carried by the gas flow from entering the second channel 610 from the first channel 604. The above-mentioned liquid bubbles may accumulate and adhere to the baffle 430. Similarly, the baffle 430 also causes the above-mentioned liquid bubbles to rupture. The liquid accumulating or rupturing on the baffle 430 can flow in the direction of gravity. The liquid accumulating or rupturing on the baffle 430 can slide or roll along the inner surface of the channel 604.

The second and third surfaces 734a, 734b can extend radially with respect to the first axis 318. The second surface 734a can be located above the third surface 734b. The second and third surfaces 734a, 734b can be separated by a maximum distance of the height 712 and a minimum distance of the height 724. The second surface 734a can be connected to the first surface 732 through a fourth surface 738a. The third surface 734b can be connected to the first surface 732 through a fifth surface 738b. The fourth and fifth surfaces 738a and 738b can be curved and have approximately the same or similar dimensions. For example, the fourth surface 738a can have a first radius 740a, and the fifth surface 738b can have a second radius 740b, where the distances of the first and second radii 740a, 740b are approximately the same or similar. The third surface 734b can extend from the first surface 732 at an angle 736. The angle 736 can be between 0 and 5 degrees. Similarly, the second surface 734a can extend from the first surface 732 at an angle similar in size to the angle 736.

The vent can have a passage that passes through at least one hole in the housing and is in fluid connection with the housing. The passage of the vent can be used to discharge gases from the housing. The vent can be coupled by at least one fastener such as a bolt and at least one fastening portion, which can abut and couple with the housing surface. The connection of the vent can be made without using a sealant and / or a clamping device. The vent and the passage passing through the vent can be composed of a first part and a second part.

The seal for the groove can be removed from the groove by hand without disassembly and will not be damaged during disassembly. The fastening portion can extend radially from the first part. The fastening portion can also extend radially from the second part. The detachable seal can at least prevent liquids such as lubricants from flowing out of the housing through the hole in the housing with respect to the vent. The detachable seal can also prevent liquids such as gases from flowing out of the housing around the hole in the housing with respect to the vent.

[0127] The vent can include a baffle. The passage through the vent can have a first section and a second section. The second section can be part of an extension section, the center line of which is perpendicular to the first section. The extension section and the second section can lead to the outlet of the vent. The baffle can extend at a non-zero angle such as a 45-degree angle with respect to the center line of the first or second section of the passage. The side of the baffle can have edges, and there is a gap between the baffle and the passage surface so that gases can flow around the baffle. The baffle can prevent liquids carried by the gases passing through the first section of the passage from entering the second section of the passage. The liquid can adhere to the surface of the baffle extending towards the first section. Liquids in the form of bubbles or droplets may be broken up by the features of the baffle such as the above-mentioned surface and edges.
