Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a reducer vent pipe structure and a vehicle. Background Art

[0002] When the reducer is running, the meshing friction of the gear transmission mechanism on it increases the temperature of the gear lubricating oil, thereby increasing the gas pressure inside the reducer housing. Since the interior of the housing is a closed structure, the high-temperature gas is not discharged, which can easily damage the oil seal and cause lubricating oil leakage at the half-shaft oil seal and the main shaft oil seal. In order to prevent the oil seal from being damaged, a vent plug seat is cast on the reducer housing, and a vent plug is installed at the vent plug seat to reduce the internal pressure of the reducer housing. At the same time, the vent plug also prevents external mud, water, and dust from splashing into the main reducer housing to prevent early wear of the gears.

[0003] When a vehicle is wading, the reducer is too low or the water level in the puddle is high, so water enters the reducer from the vent plug, causing the lubricating oil to deteriorate. Therefore, it is necessary to install a vent pipe on the reducer to increase the height of the vent plug. Due to the space limitations of surrounding parts and vehicle layout, the vent pipe is usually long and irregular in shape. During transportation, the vent pipe and reducer are generally transported separately, which makes transportation difficult and inefficient. Utility Model Content

Therefore, the above description should not be considered as limiting, but only as an example of the embodiments.

[0028] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0029] These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0030] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0031] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0032] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0033] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present invention.

[0034] The first embodiment of the utility model provides a reducer vent pipe structure, such as Figure 1-Figure 5 As shown, the reducer ventilation pipe structure includes a first connecting pipe 1, a second connecting pipe 2 and a third connecting pipe 3, one end of the first connecting pipe 1 is connected to the ventilation hole 8 of the reducer 100, one end of the second connecting pipe 2 is installed with a ventilation plug 4, the other end of the first connecting pipe 1 and the other end of the second connecting pipe 2 are connected through the third connecting pipe 3, at least one of the first connecting pipe 1, the second connecting pipe 2 and the third connecting pipe 3 is a hose, and the height of the ventilation plug 4 is higher than the wading height index of the vehicle.

[0035] The reducer ventilation pipe structure is a tubular structure with a certain length formed by connecting multiple sections of pipe bodies, wherein the first connecting pipe 1 and the second connecting pipe 2 are connected by the third connecting pipe 3, and at least one of the first connecting pipe 1, the second connecting pipe 2 and the third connecting pipe 3 is a hose, so that the reducer ventilation pipe structure can be folded, reducing the overall length of the reducer ventilation pipe structure. During transportation, the reducer ventilation pipe structure and the reducer do not need to be transported separately, but the reducer ventilation pipe structure and the reducer are transported as a whole. The folded reducer ventilation pipe structure reduces the occupied space and improves transportation efficiency.

[0036] Specifically, if the first connecting tube 1 is a hose, the second connecting tube 2 and the third connecting tube 3 are folded toward the first connecting tube 1 at the same time to achieve folding; if the second connecting tube 2 is a hose, the second connecting tube 2 is folded toward the first connecting tube 1 and the third connecting tube 3 to achieve folding; if the third connecting tube 3 is a hose, the second connecting tube 2 is folded toward the first connecting tube 1 by folding the third connecting tube 3.

[0037] The vehicle control system presets the maximum wading depth of the vehicle, which is the wading height index of the vehicle. If the wading depth of the vehicle is higher than the wading height index of the vehicle, the vehicle is at risk of failure, affecting the safety of the entire vehicle. The height of the vent plug 4 is higher than the wading height index of the vehicle, that is, when the reducer vent pipe structure is in the unfolded state, the height of the vent plug 4 is higher than the wading height index of the vehicle, to prevent water from entering the reducer vent pipe structure from the vent plug 4 during the wading process of the vehicle, and then entering the reducer 100, causing safety hazards.

[0038] In some embodiments, since the vent plug 4 becomes a communication channel between the vent pipe structure and the outside world, the height of the vent plug 4 only needs to be higher than the wading height index of the vehicle, and the height of part of the first connecting pipe 1, the second connecting pipe 2 and the third connecting pipe 3 can be lower than the wading height index of the vehicle. In this way, the layout requirements of the vent pipe can be met within a limited layout space. For example, part of the second connecting pipe 2 can be bent downward to reduce the space occupied by the vent pipe.

[0039] Specifically, the height of the vent plug 4 is at least 100 mm higher than the wading height index. The height of the vent plug 4 is determined according to the wading height of the vehicle, so that when the vehicle is wading, liquid is not easy to enter the reducer 100 from the reducer vent pipe structure, thereby avoiding potential safety hazards and extending the service life of the reducer 100. Exemplarily, for a vehicle with a wading height index of 300 mm (sedan), the height of the vent plug 4 is set to at least 400 mm, for a vehicle with a wading height index of 400 mm (SUV), the height of the vent plug 4 is set to at least 500 mm, and for a vehicle with a wading height index of 700 mm (off-road vehicle), the height of the vent plug 4 is set to at least 800 mm.

[0040] In the prior art, for ease of management, the reducer 100 and the reducer vent pipe structure have separate material numbers. In this embodiment, the reducer 100 and the reducer vent pipe structure are integrated as a whole, and the reducer 100 and the reducer vent pipe structure are integrated into an assembly, which does not need to be divided into two part numbers, thereby reducing management costs. At the same time, the number of assembly stations when assembling the reducer assembly is reduced, and work efficiency is improved.

[0041] In some embodiments, the first connecting pipe 1 and the second connecting pipe 2 are hard pipes, and the third connecting pipe 3 is a soft pipe. The third connecting pipe 3 is made of soft material, so that the first connecting pipe 1 and the second connecting pipe 2 can be relatively folded through the third connecting pipe 3, reducing the overall length of the reducer ventilation pipe structure.

[0042] When the reducer assembly is in working condition, the first connecting pipe 1 is in an unfolded state relative to the second connecting pipe 2; during transportation, the second connecting pipe 2 is folded toward the first connecting pipe 1 through the third connecting pipe 3, reducing the space occupied by the reducer ventilation pipe structure in the length direction. The third connecting pipe 3 is a transition pipe. To ensure the connection reliability of the three connecting pipes, the first connecting pipe 1 and the second connecting pipe 2 are respectively inserted into the two ends of the third connecting pipe 3, and sealed by sealants, etc., so that the third connecting pipe 3 and the first connecting pipe 1, and the third connecting pipe 3 and the second connecting pipe 2 are tightly connected to avoid gas leakage. The third connecting pipe 3 and the first connecting pipe 1, and the third connecting pipe 3 and the second connecting pipe 2 can also be connected by threaded connection or the like.

[0043] In some embodiments, the third connecting tube 3 is preferably a rubber tube, which has good pressure resistance and tensile strength and can remain stable under a certain pressure; the rubber tube shows good tolerance to a variety of chemicals and can be used normally in a variety of environments including water, gas, oil, gasoline, etc.; the rubber tube has a wide temperature resistance range and can be used in an environment of -30°C to +110°C; the rubber tube has good resilience, which is convenient for maintaining its shape after folding and maintaining its shape after the first connecting tube 1 and the second connecting tube 2 are unfolded.

[0044] In some other embodiments, the third connecting pipe 3 is preferably a PVC corrugated pipe. The corrugated pipe realizes the relative expansion and folding of the first connecting pipe 1 and the second connecting pipe 2 through its extension and compression.

[0045] In some embodiments, the first connecting pipe 1 and the second connecting pipe 2 are preferably hard steel pipes with high strength and rigidity, ensuring reliable connection between the first connecting pipe 1 and the vent hole 8 of the reducer 100, and at the same time, preventing the second connecting pipe 2 from being squeezed and bent due to insufficient strength, etc., to ensure that the vent plug 4 installed in the second connecting pipe 1 can be higher than the wading height index of the vehicle. In addition, hard steel pipes have strong adaptability and can be cut and connected as needed, which is easy to install and use. In other embodiments, the first connecting pipe 1 and the second connecting pipe 2 can also be hard pipes such as hard plastic pipes, and hard plastic pipes have lower costs.

[0046] In some embodiments, the length of the second connecting pipe 2 is greater than that of the first connecting pipe 1, and the length of the first connecting pipe 1 is greater than that of the third connecting pipe 3. In order to meet the layout requirements of the vent pipe, the length of the second connecting pipe 2 located at the outermost side can be set longer; at the same time, since the vent hole 8 is generally installed at the top of the reducer 100 and is located close to one end of the reducer 100, the second connecting pipe 2 equipped with the vent plug 4 is farthest from the vent hole 8, and the length of the second connecting pipe 2 is greater than that of the first connecting pipe 1. On the one hand, the second connecting pipe 2 located at the outermost side of the reducer can be used to meet the different layout requirements of the vent pipe. On the other hand, when the second connecting pipe 2 is folded relative to the first connecting pipe 1, the second connecting pipe 2 can be folded and placed above the reducer 100, making full use of the space above the reducer 100, rationally arranging the internal space of the vehicle, reducing the overall occupied space after the vent pipe is folded, and facilitating other operations. The length of the third connecting pipe 3 as a transition pipe is the shortest, ensuring that the first connecting pipe 1 and the second connecting pipe 2 are reliably connected. In addition, the third connecting tube 3 can be arranged close to the edge of the reducer 100, so that the second connecting tube 2 and the third connecting tube 3 can be located above the reducer 100 after being folded, making full use of the space above the reducer 100 and facilitating operation.

[0047] The first connecting tube 1 and / or the second connecting tube 2 are provided with at least one bending portion 5. The first connecting tube 1 and the second connecting tube 2 are made of hard materials and are integrally formed. According to the position arrangement of the reducer 100 and the vehicle components, the first connecting tube 1 and the second connecting tube 2 can be provided with a bending portion 5 to achieve avoidance. The first connecting tube 1 and the second connecting tube 2 are integrally formed, the processing process is simple, and the work efficiency is improved.

[0048] One end of the second connecting pipe 2 near the vent plug 4 is bent upward to form a first bent portion 6. The first bent portion 6 is bent upward so that the water vapor condensed on the surface of the first bent portion 6 can fall under the action of gravity and will not enter the reducer vent pipe structure or the reducer 100, and at the same time, the wading height of the vehicle can be increased.

[0049] like Figure 1 , Figure 4 and Figure 5As shown, a mounting seat 7 is provided at one end of the first connecting pipe 1 connected to the reducer 100, and the mounting seat 7 is clamped in the vent hole 8, and the mounting seat 7 has a connecting channel connecting the first connecting pipe 1 and the vent hole 8. A clamping portion 9 is provided on the end of the mounting seat 7 facing the reducer 100, and the clamping portion 9 is clamped in the vent hole 8 on the reducer 100, so that the vent pipe can be quickly installed. At the same time, the mounting seat 7 has a through connecting channel, one end of the connecting channel is connected to the first connecting pipe 1, and the other end (the end provided with the clamping portion 9) is connected to the vent hole 8, so that the first connecting pipe 1 is connected to the vent hole 8 on the reducer 100, so as to realize the gas transportation between the vent pipe structure and the inside of the reducer 100.

[0050] like Figure 3 As shown, the first connecting pipe 1 and the second connecting pipe 2 are respectively provided with buckles 10, which are engaged with the card interface on the vehicle. The buckle 10 is inserted into the card interface on the vehicle to fix the relative position relationship between the reducer ventilation pipe structure and the vehicle, play a role in supporting the reducer ventilation pipe structure, and improve the stability of the reducer ventilation pipe structure.

[0051] In some embodiments, the buckle 10 is fixed to the outside of the first connecting tube 1 and the second connecting tube 2 through a fixing seat. For each vehicle model, the installation position of the buckle 10 is predetermined according to the position of the card interface on the vehicle. The buckle 10 is provided on the reducer ventilation pipe structure to realize the rapid positioning and installation of the reducer ventilation pipe structure and the accurate installation position.

[0052] In some other embodiments, the buckle 10 is slidably disposed outside the first connecting pipe 1 and the second connecting pipe 2 through a sliding seat, and the reducer ventilation pipe structure can be universal for different vehicle models, thereby improving the application range of the reducer ventilation pipe structure.
