Description

Technical Field

[0001] This invention generally relates to the field of transmission or gearbox actuators used, for example, in commercial vehicles. More specifically, this invention relates to an assembly for actuating a vehicle transmission or gearbox, which operates pneumatically or hydraulically to change the gear combination, thereby altering the transmission output speed. Background Technology

[0002] It is known in the art to utilize electro-hydraulic or pneumatic transmission actuators to control operations related to changing gears and thus altering the output speed of a vehicle's transmission. For example, patent publication EP1880126A1 discloses such a conventional electro-pneumatic transmission actuator, wherein the transmission actuator is located on the top side of the transmission housing in a commercial vehicle. EP1880126A1 also shows a module for a solenoid valve, which is indicated by reference numeral "9" in the only drawing provided in that publication.

[0003] Given that such transmission actuators and their conventional solenoid valve modules within the transmission actuators are made of materials such as aluminum and / or aluminum alloys, they are relatively heavy. However, this heavy construction of the solenoid valve module affects the overall weight of the transmission actuator, and thus the overall weight of the transmission or gearbox. Furthermore, the number of manufacturing steps involved in completing this heavy, metal-based solenoid valve module is relatively high. These potential disadvantages increase the overall cost of the transmission actuator.

[0004] One objective of this invention is to address the existing need for a lighter-weight module for solenoid valves in transmission actuators, such as those in commercial vehicles. This module should also meet the design and manufacturing requirements of high-volume component suppliers, such as the applicant (for original equipment manufacturers, OEMs). Summary of the Invention

[0005] According to embodiments of the present invention, an assembly for actuating a vehicle transmission or gearbox is disclosed. The assembly includes a plurality of solenoid valves and a valve block based on a polymeric material for receiving the plurality of solenoid valves. The use of a valve block based on a polymeric material in the assembly affects, for example, the total weight of the valve block, and thus the weight of the transmission actuator of the vehicle transmission or gearbox. Furthermore, the valve block based on a polymeric material improves manufacturability and reduces, for example, the material cost of the transmission actuator of the gearbox.

[0006] For illustrative purposes only, it should be noted that the plurality of solenoid valves are electronically actuated valves that open / close fluid (hydraulic or pneumatic) paths present within the polymer-based valve block. By selectively opening and / or closing the fluid paths using the plurality of solenoid valves, the assembly actuates one or more cylinders or linear actuators (not shown). Each of the one or more cylinders or linear actuators typically includes a piston that translates linearly within the respective cylinder and a rod connected to the piston, both located within the one or more cylinders. At one end of the rod, a typical shift enabler, such as at least one shift fork (see, for example, patent publication WO2020239207A1). The shift fork actuates a jaw clutch or synchronizer present within the vehicle's gearbox to shift gears. Therefore, according to the embodiments, although vibrations occur at the polymer-based valve block due to the operation of the solenoid valve and / or due to abrupt changes in the flow rate of the fluid within the polymer-based valve block, the polymer-based valve block is still configured to maintain its shape and provide the same or similar service life as metal-based valve blocks typically used in transmission or gearbox actuators.

[0007] Furthermore, according to the above embodiments or another embodiment, the polymer-based valve block includes at least one row of equidistant receiving slots for receiving the plurality of solenoid valves. For example, a polymer-based valve block with equidistant receiving slots can achieve a uniform distribution of loads and / or stresses associated with holding the plurality of solenoid valves.

[0008] According to one or more embodiments discussed above, the polymer-based valve block includes two rows of equidistant receiving slots, which are symmetrically or asymmetrically positioned on either side of the longitudinal central axis of the polymer-based valve block or on either side of the polymer-based valve block. For example, the longitudinal central axis mentioned herein can also be replaced by a geometric plane that passes exactly through the geometric center of the polymer-based valve block.

[0009] In one embodiment relating to an asymmetrical arrangement of solenoid valves in a polymer-based valve block, a first side of the valve block may have five slots for receiving five solenoid valves, while a second side of the valve block may have four slots. In another embodiment of the invention (related to a symmetrical arrangement of solenoid valves), those skilled in the art will conclude that an equal number of solenoid valves exist on either side of the valve block. By virtue of the present invention... Figure 2This embodiment can be readily understood from the description provided in the associated sections below. Regardless of the arrangement or number of solenoid valves or their distribution on either side of the valve block, the use of polymeric materials to implement the valve block allows for easy customization or modification of the design as needed. This design change is easier to implement when the valve block is based on a polymeric material compared to conventional metal-based valve blocks.

[0010] According to one or more of the above embodiments, the valve block based on the polymer material is manufactured by injection molding. Considering the material selection of the valve block, injection molding is not only low-cost but also easy to mass-produce.

[0011] Furthermore, in an exemplary embodiment of the invention, the assembly further includes a plurality of bolts, and at least two of the plurality of bolts are used to attach each of the plurality of solenoid valves to a valve block based on a polymeric material. It should be understood that the at least two bolts for attaching each of the plurality of solenoid valves are for the purpose of better assembly and additional clamping, for example, when securing the solenoid valve relative to the valve block based on the polymeric material. Furthermore, the environment surrounding the assembly of the invention is within and around a vehicle transmission, where vibrations are significant due to relative proximity, for example, to an internal combustion engine. Therefore, providing more than one bolt to attach each solenoid valve to the valve block is considered advantageous, as it allows the holding force to be distributed substantially evenly on either side of the solenoid valve.

[0012] In the same or different embodiments of the invention, each of the plurality of bolts is threaded at either one of its first and second ends. As described above, the valve block of the invention is made of a polymeric material. The choice of polymeric material makes it undesirable to use threads at only one end of the bolts, for example, because it is found that the polymeric material provides limited support when only one end of the plurality of bolts is threaded. Therefore, each of the plurality of bolts is threaded at either one of its first and second ends.

[0013] However, in the same embodiment as the previous paragraph, each of the plurality of bolts has a standard metric thread at its first end, and each of the plurality of bolts has a self-forming or self-tapping thread at its second end, such that when the second end is inserted into the polymer-based valve block, a robust receiving slot is formed in the polymer-based valve block.

[0014] In one of the most preferred embodiments of the invention, a self-forming or self-tapping thread is provided at the second end of each of the plurality of bolts, and a standard metric thread is provided at the first end of each of the plurality of bolts. Specifically, inserting a metric thread into a polymer-based valve block may not be able to withstand the required load due to, for example, the weight of a solenoid valve, and furthermore, any rework of the metric thread in the polymer-based valve block may result in damage to the thread in the polymer-based valve block. Moreover, this type of thread damage may potentially lead to the scrapping of the polymer-based valve block. Therefore, the second end advantageously or preferably has a self-forming or self-tapping thread, which is formed instantaneously, for example, while the solenoid valve is being assembled to the polymer-based valve block.

[0015] It should also be understood that self-forming or self-tapping threads naturally form threads on the material into which they are inserted, wherein the material into which the self-forming or self-tapping thread is inserted is softer than that of a screw or bolt with a self-tapping or self-forming thread.

[0016] In a preferred embodiment of the invention, the first end of each of the plurality of bolts is assembled with a metric nut to "securely fix" the corresponding solenoid valve to the position relative to the valve block. A standard metric thread at the second end of each of the plurality of bolts further supports (in addition to the self-tapping thread at the first end of the bolt) the polymer-based valve block to hold the solenoid valve in place.

[0017] As per the preceding paragraph, due to the presence of a valve block based on a polymeric material, or as a further advantage, the polymeric material-based valve block does not have any pre-formed threads, but only bores specifically designed to receive the plurality of bolts. Preferably, these bores are present before the bolts are assembled into the valve block, because, for example, self-tapping threads exist at the second end of each of the plurality of bolts. For example, a plurality of bores corresponding to the number of bolts can be provided in the polymeric material-based valve block. These bores form threads when a bolt with self-tapping threads at its second end is inserted. For mass-production manufacturers like the applicant, this can result in a reduction of one manufacturing step. In larger-scale or high-volume manufacturing, reducing manufacturing steps can be crucial in certain situations for maintaining cost competitiveness.

[0018] According to one or more embodiments discussed above, each of the plurality of bolts has a second end further provided with a flange for limiting the length of each of the plurality of bolts that can be inserted into the polymer-based valve block. In this advantageous embodiment, in addition to defining the boundary where the second end of each of the plurality of bolts is provided with a self-tapping or self-forming thread, the flange may also optionally act as an axial support to linearly orient the plurality of bolts relative to the polymer-based valve block.

[0019] According to embodiments of the invention, the polymer-based valve block comprises a glass fiber-reinforced thermoplastic material or contains polyphthalamide. Particularly or advantageously, the polymer-based valve block may comprise 50% of a glass fiber-reinforced engineering thermoplastic material based on a semi-crystalline, partially aromatic copolyamide. The choice of glass fiber-reinforced thermoplastic material is particularly suitable for injection molding processes, by which the polymer-based valve block according to the invention can be manufactured.

[0020] More importantly, compared to other polyphthalamides, glass fiber reinforced thermoplastics exhibit the properties required for use at high temperatures in components (according to the invention) for actuating vehicle transmissions or gearboxes, thus providing parts that are harder, stronger, and have better thermal deformation stability and chemical resistance. Because vehicle transmissions or gearboxes are located near internal combustion engines, this material selection is particularly suitable for the applications envisioned in this invention.

[0021] Furthermore, one of the significant advantages of using glass fiber reinforced thermoplastic material as part of the polymer-based valve block according to the invention is its ability to be used directly in the injection molding process without any pre-drying, provided that the packaging carrying the glass fiber reinforced thermoplastic material is not damaged before the injection molding process begins.

[0022] For example, the melting point of the glass fiber reinforced thermoplastic material used as part of the valve block may be higher than 300°C. Another example is that the density of the material used as part of the valve block is higher than 1 g / cm³. 3 Or preferably, about 1.65 g / cm³ 3 .

[0023] Furthermore, depending on the type of actuator used in the transmission or gearbox, according to one or more embodiments discussed above, each of the plurality of solenoid valves is configured to open and / or close at least one fluid path within a polymer-based valve block, wherein the at least one fluid path is configured to be operated using hydraulic (incompressible) or pneumatic (compressible) fluid. For example, pneumatic transmission actuators can be used in commercial vehicles, while hydraulic transmission actuators can be used in passenger cars.

[0024] According to an embodiment, a method for manufacturing a component according to any of the above embodiments is disclosed, wherein the method comprises heating a polymeric material in an injection molding machine at a temperature range of 60°C to 350°C, the polymeric material being used to manufacture a valve block based on the polymeric material.

[0025] According to another embodiment, a gearbox or transmission actuator including components according to any of the above embodiments is disclosed.

[0026] According to another embodiment of the present invention, the use of a component according to any of the above embodiments in connection with a vehicle transmission or gearbox of a commercial vehicle is disclosed. Attached Figure Description

[0027] Figure 1 The diagram illustrates conventional components used to actuate a vehicle's transmission or gearbox; and

[0028] Figure 2 The illustration shows an assembly according to the invention for actuating a vehicle transmission or gearbox. Detailed Implementation

[0029] Figure 1 The diagram illustrates a device used to actuate a vehicle's transmission or gearbox. Figure 1 (not shown) Conventional component 100.

[0030] The standard component 100 includes a valve block 102. For example... Figure 1 The valve block 102 shown is symmetrically arranged on either side of axis A-A'. The valve block 102 of the conventional assembly 100 includes approximately nine receiving slots 118 for receiving nine solenoid valves 110. However, this is provided merely for illustrative purposes. The number of solenoid valves 110 can naturally vary depending on the type of vehicle transmission or gearbox employing the conventional assembly 100. Figure 1 In the conventional valve block 102 shown, during assembly, once the solenoid valve 110 is received within the slot 118 of the valve block 102, the solenoid valve 110 is secured to the valve block 102 using metal screws 112. Each of the screws 112 may contain a full thread in the region 114 of the screw 112.

[0031] Furthermore, the screw 112 is inserted through the hole 118 present in the frame of the solenoid valve 110 and is positioned to coincide with the hole 116 present in the valve block 102.

[0032] It should be noted that Figure 1 The valve block 102 shown is made of a castable metal such as aluminum. There are various reasons why aluminum could be chosen as the material for manufacturing the valve block 102. These reasons are beyond the scope of this invention. However, it should be noted that using aluminum as the material for manufacturing the valve block 102 results in corresponding design and processing limitations. Furthermore, due to these design and processing limitations, the use of aluminum affects the overall weight and cost of the valve block 102.

[0033] As described above, the hole 116 present at valve block 102 should have a corresponding thread to receive metal screw 112. Naturally, this results in additional manufacturing steps when completing valve block 102 so that solenoid valve 110 can be assembled with valve block 102 using screw 112.

[0034] One of the objectives of this invention is to provide an economical solution that takes into account not only the design and manufacturing limitations of the valve block 102, but also to provide a solution that improves the applicability of the valve block 102 associated with the solenoid valve 110.

[0035] Figure 2 The illustration shows an assembly 200 according to the invention for actuating a vehicle transmission or gearbox.

[0036] According to this embodiment, component 200 includes a plurality of solenoid valves 210 and a polymer-based valve block 202 for receiving the plurality of solenoid valves 210. The use of the polymer-based valve block 202 in component 200 affects, for example, the total weight of the valve block 202, and therefore the vehicle's transmission or gearbox (…). Figure 2 The weight of the transmission actuator (not shown) is affected. Furthermore, the valve block 202 based on polymer materials improves manufacturability and reduces material costs for transmission actuators, such as those in gearboxes.

[0037] In addition, such as Figure 2 As shown, the polymer-based valve block 202 includes at least one row of equidistantly positioned receiving slots 218 for receiving the plurality of solenoid valves 210. For example, the polymer-based valve block 202 with equidistantly positioned receiving slots 218 can achieve an equal distribution of loads and / or stresses associated with holding the plurality of solenoid valves 210. During the use of, for example, the polymer-based valve block 202, stresses caused by vibrations of the vehicle transmission or gearbox should also be evenly distributed, and in this regard, the equidistant positioning of the slots 218 for receiving the solenoid valves 210 is advantageous. Furthermore, the spatial distribution of the solenoid valves 210 is optimally designed to improve the housing of the solenoid valves 210 in the transmission actuator of the vehicle transmission or gearbox. Figure 2 The overall package (not shown in the image) is inside the package.

[0038] According to the same or different embodiments, the polymer-based valve block 202 includes two rows of equidistant receiving slots 218, which are symmetrically or asymmetrically positioned on either side of the longitudinal central axis (A-A') of the polymer-based valve block 202 or on either side of the two sides 204, 206 of the polymer-based valve block 202.

[0039] For example, the longitudinal central axis A-A' can also be the geometric center that passes exactly through the valve block 202 ( Figure 2 The geometric plane (not shown in the figure) is used instead. In one embodiment (related to the asymmetrical arrangement of solenoid valve 210), as... Figure 2As shown, the first side 204 (visible side) of the valve block 202 may have five slots 218 for receiving five solenoid valves 210, while the second side 206 of the valve block 202 may have four slots 218. Figure 2 Not shown in the image, but because in Figure 2 It can be inferred that there are four solenoid valves 210 near the second side 206 of the valve block 202. In another embodiment of the invention (related to the symmetrical arrangement of the solenoid valves 210), those skilled in the art will conclude that there are an equal number of solenoid valves 210 on either side 204 and 206 of the valve block 202.

[0040] According to the same or different embodiments, the valve block 202 based on polymeric materials is manufactured by injection molding. Considering the material selection of the valve block 202, injection molding is not only low-cost but also easy for mass production.

[0041] Furthermore, according to this embodiment, component 200 further includes a plurality of bolts 212, and at least two of the plurality of bolts are used to attach each of the plurality of solenoid valves 210 to a valve block 202 based on a polymeric material. It should be understood that the at least two bolts 212 for attaching each of the plurality of solenoid valves 210 are for the purpose of better assembly and additional clamping. The environment surrounding component 200 exists within and around the vehicle transmission, where vibrations are significant due to their proximity to, for example, an internal combustion engine. Therefore, it is advantageous to provide more than one bolt 212 to attach each solenoid valve 210 to the valve block 202.

[0042] In the same embodiment, each of the plurality of bolts 212 is threaded at either one of its first end 212a and second end 212b. As described above, the valve block 202 of the present invention is made of a polymeric material. The choice of polymeric material makes it unadvantageous to use threads at only one end of the ends 212a and 212b, for example, because it is found that the polymeric material provides limited support when only one end of the plurality of bolts 212 is threaded. Therefore, each of the plurality of bolts 212 is threaded at either one of its first end 212a and second end 212b.

[0043] However, in the same embodiment as the previous paragraph, the first end 212a of each of the plurality of bolts 212 is provided with a standard metric thread, and the second end 212b of each of the plurality of bolts 212 is provided with a self-forming or self-tapping thread, such that when the second end 212b is inserted into the polymer-based valve block 202, a robust receiving slot is formed in the polymer-based valve block 202. It should be noted that in the same embodiment, each solenoid valve 210 includes at least two cylindrical receiving slots 208 for receiving the plurality of bolts 212. Therefore, the second ends 212b of the plurality of bolts 212 are inserted into the valve block 202, while the first ends 212a of the plurality of bolts 212 are inserted via the slots 208 of the solenoid valve 210.

[0044] In one of the most preferred embodiments of the invention, a self-forming or self-tapping thread is provided at the second end 212b of each of the plurality of bolts 212, and a standard metric thread is provided at the first end 212. Specifically, inserting a metric thread into a polymer-based valve block 202 may not withstand the required loads applied by the solenoid valve 210, and furthermore, any rework of the metric thread provided in the polymer-based valve block 202 may result in damage to the threads in the polymer-based valve block 202. This could potentially lead to the scrapping of the polymer-based valve block 202. Therefore, the second end 212b is advantageously or preferably provided with a self-forming or self-tapping thread. It should be understood that a self-forming or self-tapping thread naturally forms a thread in the material into which it is inserted, wherein the material into which the self-forming or self-tapping thread is inserted is softer than a screw or bolt with a self-tapping or self-forming thread.

[0045] Therefore, the first end 212a of each of the plurality of bolts 212 is assembled with a metric nut 212c to "securely secure" the position of the corresponding solenoid valve from the plurality of solenoid valves. The standard metric thread at the second end 212b of each of the plurality of bolts 212 further supports the polymer-based valve block 202 to hold the solenoid valve 210 in place.

[0046] Due to the presence of a polymer-based valve block 202, or as a further advantage, the polymer-based valve block 202 does not have any pre-formed threads, but only general eyelets specifically for receiving a plurality of bolts 212, preferably having eyelets before the bolts 212 are assembled into the valve block 202, because, for example, self-tapping threads are present at the second end 212b of each of the plurality of bolts 212. More simply, the polymer-based valve block 202 comprises cylindrical and / or conical eyelets for receiving a plurality of bolts 212. For example, while assembling the bolts 212 into the polymer-based valve block 202, threads are formed within said eyelets by performing a tightening motion (i.e., a rotational motion). According to one or more embodiments discussed above, the second end 212b of each of the plurality of bolts 212 is additionally provided with a flange 212d for limiting the length of each of the plurality of bolts 212 that can be inserted into the polymer-based valve block 202. In this advantageous embodiment, in addition to defining the boundaries of the second end 212b of each of the plurality of bolts 212 with self-tapping or self-forming threads, the flange 212d may also optionally act as an axial support to linearly orient the bolts 212 relative to the polymer-based valve block 202.

[0047] In the same or different embodiments as discussed above, Figure 2 The image shows multiple pre-formed holes 216 into which multiple bolts 212 are received. (See image for details.) Figure 2 As shown, each of the plurality of preformed eyelets 216 may optionally include a stepped portion 216a for receiving flanges 212d, which are disposed at the second end 212b of the plurality of bolts 212. This stepped portion 216a can assist in more securely securing the bolts 212 to the polymer-based valve block 202.

[0048] According to embodiments of the invention, the polymer-based valve block 202 comprises a glass fiber reinforced thermoplastic material or contains polyphthalamide. Particularly or advantageously, the polymer-based valve block 202 may comprise 50% of a glass fiber reinforced engineering thermoplastic material based on a semi-crystalline, partially aromatic copolyamide. The choice of glass fiber reinforced thermoplastic material is particularly suitable for injection molding processes, by which the polymer-based valve block 202 according to the invention can be manufactured.

[0049] More importantly, compared to other polyphthalamides, glass fiber reinforced thermoplastic materials exhibit the desired properties at high temperatures for use in the components 200 for actuating vehicle transmissions or gearboxes according to the invention, thus providing parts that are harder, stronger, and have better thermal deformation stability and chemical resistance. Because vehicle transmissions or gearboxes are located near internal combustion engines, this material selection is particularly suitable for the applications envisioned in this invention.

[0050] Furthermore, one of the significant advantages of using glass fiber reinforced thermoplastic material in the polymer-based valve block 202 according to the present invention is its ability to be used directly in the injection molding process without any pre-drying, provided that the packaging carrying the glass fiber reinforced thermoplastic material is not damaged before the injection molding process begins.

[0051] Furthermore, depending on the type of actuator used in the transmission or gearbox, according to one or more embodiments discussed above, each of the plurality of solenoid valves 210 is configured to open and / or close at least one fluid path within the polymer-based valve block 202, wherein said at least one fluid path is configured to be operated using hydraulic (incompressible) or pneumatic (compressible) fluid. For example, pneumatic transmission actuators can be used in commercial vehicles, while hydraulic transmission actuators can be used in passenger cars.
