[0027] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 and Figure 2 Description of a fixed bracket 100 according to a first aspect embodiment of the present invention.

[0028] like Figure 1 and Figure 2 As shown, the fixing bracket 100 according to a first aspect embodiment of the present invention includes a fixing part 10, a transition part 20, and a connecting part 30. The fixing part 10 is adapted to be connected to a gearbox 60. The transition part 20 is provided in a first direction (e.g., ...). Figure 1 On one side of the vertical direction, and the transition portion 20 in the second direction (e.g., Figure 1 The transition portion 20 extends obliquely in the direction away from the fixing portion 10 in the left-right direction, and the second direction is perpendicular to the first direction. The connecting portion 30 is provided on the side of the transition portion 20 away from the fixing portion 10. The connecting portion 30 and the fixing portion 10 are respectively located on both sides of the transition portion 20 in the second direction. At least one mounting hole 31 is formed on the connecting portion 30 for mounting the oil pipe 70 or the air pipe 80.

[0029] exist Figure 1 and Figure 2 In the example, the fixing part 10 is connected to the top cover of the gearbox 60, the transition part 20 and the connecting part 30 are located on one side of the gearbox 60, and the connecting part 30 of the fixing bracket 100 is provided with two mounting holes 31. The operator can install the oil pipe 70 or the air pipe 80 on the connecting part 30 of the fixing bracket 100. Compared with the prior art of directly connecting the clutch oil pipe 70 and the air pipe 80 to the clutch booster at the bottom of the gearbox 60, this avoids the operator from performing the connection operation at the bottom of the gearbox 60, thereby reducing the risk of operation.

[0030] Furthermore, the transition portion 20 of the fixed bracket 100 extends obliquely in the second direction away from the fixed portion 10, providing a more reasonable installation path for the oil pipe 70 or air pipe 80, making the installation of the oil pipe 70 or air pipe 80 smoother, thereby reducing installation difficulty and improving installation efficiency. Moreover, the oblique extension of the transition portion 20 avoids positional interference with components on the gearbox 60, allowing the fixed bracket 100 to be installed on different gearboxes 60, thus increasing the applicability of the fixed bracket 100. In addition, the fixed bracket 100 has a simple overall structure, resulting in lower manufacturing difficulty and cost.

[0031] According to the present invention, the fixed bracket 100 connects the fixed part 10 of the fixed bracket 100 to the gearbox 60, the transition part 20 extends obliquely in a direction away from the fixed part 10, and at least one mounting hole 31 is formed on the connecting part 30, thereby reducing the operational danger and installation difficulty, improving the installation efficiency, expanding the applicability of the fixed bracket 100, and reducing the production difficulty and cost of the fixed bracket 100.

[0032] According to some embodiments of the present invention, the connecting portion 30 includes a first connecting segment 32 and a second connecting segment 33. Specifically, one end of the first connecting segment 32 is connected to the transition portion 20, and the first connecting segment 32 extends along a second direction. The second connecting segment 33 is connected to the first connecting segment 32 in a third direction (e.g., ...). Figure 1 At one end of the first connecting section 32 (in the front-back direction), the second connecting section 33 extends away from the transition portion 20 in the first direction, and the third, second, and first directions are orthogonal to each other. Mounting holes 31 are formed on both the first and second connecting sections 32 and 33.

[0033] For example, in Figure 1 In the example, both the first connecting segment 32 and the second connecting segment 33 are rectangular sheet structures, and the first connecting segment 32 and the second connecting segment 33 are smoothly transitioned. The mounting hole 31 on the first connecting segment 32 has a larger diameter and is located at the center of the first connecting segment 32, and is used to install the air pipe 80. The mounting hole 31 on the second connecting segment 33 has a smaller diameter and is located at the edge of the second connecting segment 33, and is used to install the oil pipe 70.

[0034] In practice, the connector is first assembled into the mounting holes 31 on the first connecting section 32 and the second connecting section 33. Then, the oil pipe 70 and / or air pipe 80 are inserted into the connector in the mounting holes 31 to complete the installation of the oil pipe 70 and / or air pipe 80, reducing installation difficulty and improving installation efficiency. Moreover, mounting holes 31 are provided on both the first connecting section 32 and the second connecting section 33, allowing workers to select the corresponding mounting hole 31 according to the different routes and positions of the oil pipe 70 or air pipe 80, thus improving installation flexibility.

[0035] In some alternative embodiments, the connecting portion 30 further includes a third connecting segment 34, which connects to the first connecting segment 32 at the other end in a third direction. The third connecting segment 34 extends in a direction toward the transition segment in the first direction, and a mounting hole 31 is formed on the third connecting segment 34.

[0036] like Figure 1 As shown, the third connecting section 34 is roughly rectangular in shape, and the first connecting section 32 and the third connecting section 34 transition smoothly. In the first direction, the second connecting section 33 and the third connecting section 34 are located on both sides of the first connecting section 32. Compared with the first connecting section 32 and the second connecting section 33, the overall size of the third connecting section 34 is smaller, and the mounting hole 31 on the third connecting section 34 is a rectangular hole. In practice, the operator can secure the shift assist air hose 82 to the mounting hole 31 on the third connecting section 34 using cable ties.

[0037] By incorporating the third connecting section 34, more location options are provided for the installation of the air pipe 80 / oil pipe 70, improving installation flexibility. Furthermore, the second connecting section 33 and the third connecting section 34 are located on either side of the first connecting section 32, fully utilizing the space around the transmission and optimizing the spatial layout of the entire clutch system 200, making it more compact. Moreover, this arrangement provides a more reasonable installation path for the oil pipe 70 or air pipe 80, making their installation smoother and thus improving installation efficiency.

[0038] According to some embodiments of the present invention, the transition section 20 includes: a first transition segment 21, a second transition segment 22 and a third transition segment 23.

[0039] Specifically, one end of the first transition segment 21 is connected to the fixing part 10, the first transition segment 21 extends along a first direction, and the first transition segment 21 extends obliquely along a third direction. One end of the second transition segment 22 is connected to the other end of the first transition segment 21, and the second transition segment 22 extends obliquely along a second direction. One end of the third transition segment 23 is connected to the other end of the second transition segment 22, and the other end of the third transition segment 23 is connected to the first connecting segment 32, and the third transition segment 23 extends along the first direction. The angle between the first transition segment 21 and the second transition segment 22 is an obtuse angle, and / or the angle between the third transition segment 23 and the second transition segment 22 is an obtuse angle.

[0040] For example, in Figure 1In the example, the angle between the first transition segment 21 and the second transition segment 22 is an obtuse angle, and the angle between the third transition segment 23 and the second transition segment 22 is an obtuse angle; or, only the angle between the first transition segment 21 and the second transition segment 22 is an obtuse angle (not shown in the figure); or, only the angle between the third transition segment 23 and the second transition segment 22 is an obtuse angle (not shown in the figure).

[0041] This design allows the fixed bracket 100 to better adapt to different installation environments. In situations where space is limited around the gearbox 60, the transition section 20's structure effectively utilizes space and avoids interference with other surrounding components, thus optimizing the layout of the clutch system 200. Furthermore, the multiple transition sections allow it to better conform to the routing and path of the oil pipe 70 or air pipe 80, making it easier for workers to connect the oil pipe 70 or air pipe 80 to suitable positions on the fixed bracket 100 during installation, thereby improving installation efficiency.

[0042] According to some embodiments of the present invention, the included angle between the second transition segment 22 and the first transition segment 21 is α, and the included angle between the second transition segment 22 and the third transition segment 23 is β, wherein α and β satisfy: 120.2°<α<147.0°, 121.0°<β<148.0° respectively.

[0043] When α ≤ 120.2°, the angle between the second transition section 22 and the first transition section 21 is too small, resulting in a large degree of bending of the air pipe 80 or oil pipe 70 at the turning point. This can easily lead to significant stress concentration in the air pipe 80 or oil pipe 70, potentially reducing their service life or even causing safety hazards such as pipe rupture or leakage. Furthermore, the small angle between the second transition section 22 and the first transition section 21 makes it impossible to conform to the direction and path of the oil pipe 70 or air pipe 80, affecting the piping direction and layout of the clutch system 200. When α ≥ 147.0°, the angle between the second transition section 22 and the first transition section 21 is too large, which may cause the transition section 20 to interfere with other components around the gearbox 60, affecting the overall layout of the clutch system 200. Therefore, by setting the included angle α between the second transition section 22 and the first transition section 21 between 120.2° and 147.0°, the service life of the air pipe 80 or oil pipe 70 can be guaranteed, safety hazards caused by stress concentration can be avoided, and the pipeline routing and layout of the clutch system 200 can be optimized.

[0044] When β ≤ 121.0°, the angle between the second transition section 22 and the third transition section 23 is too small, resulting in a large degree of bending of the air pipe 80 or oil pipe 70 at the turning point. This can easily lead to significant stress concentration in the air pipe 80 or oil pipe 70, potentially reducing their service life or even causing safety hazards such as pipe rupture or leakage. Furthermore, the small angle between the second transition section 22 and the third transition section 23 makes it impossible to conform to the direction and path of the oil pipe 70 or air pipe 80, affecting the piping direction and layout of the clutch system 200. When β ≥ 148.0°, the angle between the second transition section 22 and the third transition section 23 is too large, which may cause the transition section 20 to interfere with other components around the gearbox 60, affecting the overall layout of the clutch system 200. Therefore, by setting the included angle β between the second transition section 22 and the third transition section 23 between 121.0° and 148.0°, the service life of the air pipe 80 or oil pipe 70 can be guaranteed, safety hazards caused by stress concentration can be avoided, and the pipeline routing and layout of the clutch system 200 can be optimized.

[0045] In some alternative embodiments, at least one through hole 24 is formed on the transition portion 20.

[0046] like Figure 1 As shown, there are two through holes 24. One through hole 24 is located on the second transition section 22. This through hole 24 is an elongated hole, and its length direction is the same as that of the second transition section 22. The other through hole 24 is located at the connection between the second transition section 22 and the third transition section 23. This through hole 24 is also approximately an elongated hole. The placement of the through holes 24 reduces the overall weight of the fixed bracket 100 without affecting its function, which is beneficial for the lightweight design of the fixed bracket 100. Moreover, the placement of the through holes 24 can prevent the fixed bracket 100 from interfering with the position of other surrounding components, which is beneficial for optimizing the overall layout of the clutch system 200.

[0047] Specifically, the fixing bracket 100 further includes a first connecting piece 40 and a second connecting piece 50. The first connecting piece 40 is disposed on the third-direction side of the fixing portion 10 and extends in a first direction away from the fixing portion 10. The second connecting piece 50 is disposed on the third-direction side of the transition portion 20. The first connecting piece 40 and the second connecting piece 50 are located on the same side of the transition portion 20, and both the first connecting piece 40 and the second connecting piece 50 have mating holes 41 formed on them.

[0048] like Figure 1 and Figure 2As shown, the first connecting piece 40, the second connecting piece 50, and the third connecting part 30 are located on the same side of the transition part 20, and the structures of the first connecting piece 40, the second connecting piece 50, and the third connecting part 30 are similar, all being rectangular sheet structures. The mating holes 41 on the first connecting piece 40 and the second connecting piece 50 are rectangular holes. In specific implementation, the operator can first arrange the shift assist air pipe 82 along the length of the fixed bracket 100, and then use cable ties to tie and fix the shift assist air pipe 82 to the fixed bracket 100 at the mating holes 41 of the first connecting piece 40 and the second connecting piece 50 and the mounting holes 31 on the third connecting section 34, respectively.

[0049] The first connecting piece 40 and the second connecting piece 50 provide multiple fixing points for the shift power assist air hose 82, ensuring accurate and stable installation and effectively preventing displacement or shaking of the shift power assist air hose 82 due to vibration during vehicle operation. Furthermore, the space around the fixing bracket 100 is fully utilized, making the overall layout of the fixing bracket 100 more compact. This achieves effective fixing of the shift power assist air hose 82 within a limited space, facilitating the rational use of vehicle interior space. In addition, the installation via cable ties and mating holes 41 is more convenient and faster, allowing workers to complete the installation and fixing of the shift power assist air hose 82 more efficiently, improving assembly efficiency and facilitating later maintenance and repair. When it is necessary to replace or adjust the shift power assist air hose 82, only the cable ties need to be untied.

[0050] According to some embodiments of the present invention, the fixed bracket 100 is a sheet metal part, and the thickness of the fixed bracket 100 is D, wherein D satisfies: 3.6mm≤D≤4.4mm.

[0051] When D < 3.6mm, the thickness of the fixing bracket 100 is too small, resulting in low structural strength and susceptibility to deformation. This makes it difficult to effectively secure the air pipe 80, affecting the normal operation of the oil pipe 70 or air pipe 80, and potentially causing them to detach, posing a safety hazard. When D > 4.4mm, the thickness of the fixing bracket 100 is too large, increasing its overall weight and material cost, which is detrimental to the vehicle's lightweight design. Furthermore, an excessively thick fixing bracket 100 requires more installation space, potentially interfering with other components within the vehicle and limiting its installation location. Therefore, by setting the thickness D of the fixing bracket 100 between 3.6mm and 4.4mm, effective securing of the oil pipe 70 or air pipe 80 is ensured while reducing the overall weight and material cost of the fixing bracket 100, thus promoting lightweight vehicle design and avoiding interference with other components within the vehicle.

[0052] According to a second aspect of the present invention, a clutch system 200 includes: a gearbox 60, a fixed bracket 100, an oil pipe 70, and an air pipe 80.

[0053] The fixing part 10 of the fixed bracket 100 is connected to the gearbox 60, and the fixed bracket 100 is the fixed bracket 100 according to the first aspect embodiment of the present invention described above. The oil pipe 70 includes a first oil pipe 71 and a second oil pipe 72, which are connected by a first connector 73 and are located at the mounting hole 31 of the second connecting section 33 of the fixed bracket 100. The air pipe 80 includes a first air pipe 81 and a second air pipe 80 (not shown in the figure), which are connected by a second connector 83, which is located at the mounting hole 31 of the first connecting section 32 of the fixed bracket 100.

[0054] According to the clutch system 200 of this utility model embodiment, by adopting the above-mentioned fixed bracket 100, the operational hazards and installation difficulties are reduced, and the installation efficiency is improved.

[0055] It should be noted that the second air pipe 80 is a branch air pipe 80 of the brake main bundle on the longitudinal beam of the frame, and this application does not impose any specific restrictions on it.
