[0036] Please refer to Figure 1 , Figure 1A schematic view of a vehicle 1000 is provided for some embodiments of the present application. The vehicle 1000 mentioned in embodiments of the present application comprises a suspension system 100 and a wheel 200, the suspension system 100 is connected to one side of the wheel 200. The suspension system 100 is a device that connects the frame and the axle in the vehicle 1000 flexibly, and is generally composed of elastic elements, guide mechanisms and shock absorbers 10, etc. The suspension system 100 is used to alleviate the impact of uneven road surface to the frame, so as to improve the comfort of the vehicle.
[0037] The shock absorber 10 is usually a hydraulic shock absorber 10, which is located on one side of the wheel 200 and is supported between the frame and the axle. The working principle of the shock absorber 10 is to consume vibration energy by using liquid damping. When the frame (or vehicle body) and the axle appear relative movement due to vibration, the piston in the shock absorber 10 moves up and down, and the oil in the shell of the shock absorber 10 repeatedly flows from one cavity (compression valve) to another cavity (recovery valve) through some narrow apertures. At this time, the friction between the aperture wall and the oil and the internal friction between the oil molecules form a damping force to the vibration, so that the vibration energy of the vehicle body and the frame is converted into heat energy of the oil, which is then absorbed by the oil and the shell of the shock absorber 10, and then dissipated to the atmosphere, thereby improving the driving smoothness of the vehicle 1000 and improving the comfort of the vehicle 1000.
[0038] In the related art, the size of the shock absorber 10 is large, so that the shock absorber 10 occupies a large wheel space, thereby affecting the integration of the reducer and the motor driving system.
[0039] In order to reduce the occupation of the wheel space by the shock absorber 10, the present application provides a shock absorber 10, which comprises a cylinder body 11, a compression electromagnetic valve 12, a recovery electromagnetic valve 13 and a bracket 14. The compression electromagnetic valve 12 is arranged on one side of the cylinder body 11 in the circumferential direction, the recovery electromagnetic valve 13 is arranged on one side of the cylinder body 11 in the circumferential direction and is arranged in a spaced manner with the compression electromagnetic valve 12, and the bracket 14 is welded with one end of the cylinder body 11 in the axial direction.
[0040] In such a shock absorber 10, the bracket 14 and the cylinder body 11 are connected by welding, which can reduce the use of mounting parts, so that the axial size of the shock absorber 10 is small, thereby reducing the wheel space occupation of the shock absorber 10.
[0041] Please refer to Figure 1 The suspension system 100 mentioned in embodiments of the present application comprises a shock absorber 10 and a control arm 20, the shock absorber 10 is connected to the control arm 20 through the bracket 14, and the suspension system 100 is connected to one side of the wheel 200 through the control arm 20. The control arm 20 can be made of metal materials, such as steel or aluminum alloy.
[0042] Please refer to Figure 2 and Figure 3 ,Figure 2 and Figure 3 A schematic view of a damper 10 according to some embodiments of the present application is provided. The damper 10 according to embodiments of the present application includes a cylinder 11, a compression solenoid valve 12, a rebound solenoid valve 13, and a bracket 14. The compression solenoid valve 12 is disposed on a circumferential side of the cylinder 11, the rebound solenoid valve 13 is disposed on a circumferential side of the cylinder 11 and is spaced apart from the compression solenoid valve 12, and the bracket 14 is welded to an axial end of the cylinder 11.
[0043] Specifically, the cylinder 11 can be a circular cylindrical structure, and the cylinder 11 and the bracket 14 can be made of a metal material capable of being welded, including but not limited to steel. The compression solenoid valve 12 and the rebound solenoid valve 13 are disposed on a circumferential side of the cylinder 11, which means that the central axis of the compression solenoid valve 12 and the central axis of the rebound solenoid valve 13 are both perpendicular to the central axis of the cylinder 11.
[0044] The cylinder 11 can have a main flow passage formed therein, which is adapted to be connected to working cylinders of the damper 10, such as a rebound chamber and a compression chamber in the working cylinders. The compression solenoid valve 12 and the rebound solenoid valve 13 are connected to the main flow passage to adjust the flow rate of fluid between the compression chamber and the rebound chamber through the main flow passage. The compression solenoid valve 12 is used to adjust the damping force of the fluid in the compression condition of the damper 10, so that the fluid in the compression chamber can flow to the rebound chamber through the compression solenoid valve 12 to realize the compression condition of the damper 10; the rebound solenoid valve 13 is used to adjust the damping force of the fluid in the rebound condition of the damper 10, so that the fluid in the rebound chamber can flow to the compression chamber through the rebound solenoid valve 13 to realize the rebound condition of the damper 10, thereby realizing accurate control of the damping force in different conditions.
[0045] In the above-mentioned embodiments, the bracket 14 is connected to the cylinder 11 by welding, which can reduce the use of mounting parts and make the axial size of the damper 10 smaller, thereby reducing the occupation of the damper 10 to the wheel space.
[0046] Please refer to Figure 2 In some embodiments, the compression solenoid valve 12 is welded to the cylinder 11, and / or the rebound solenoid valve 13 is welded to the cylinder 11.
[0047] Specifically, the compression solenoid valve 12 can be welded to the cylinder 11, and the rebound solenoid valve 13 can be fixedly connected to the cylinder 11 by other means, or the rebound solenoid valve 13 can be welded to the cylinder 11, and the compression solenoid valve 12 can be fixedly connected to the cylinder 11 by other means, or both the compression solenoid valve 12 and the rebound solenoid valve 13 can be welded to the cylinder 11.
[0048] In the above embodiments, the compression solenoid valve 12 and / or the recovery solenoid valve 13 are welded with the cylinder body 11, which can improve the connection strength between the compression solenoid valve 12 and / or the recovery solenoid valve 13 and the cylinder body 11, thereby improving the structural stability of the shock absorber 10.
[0049] Please refer to Figure 3 In some embodiments, the central axis of the compression solenoid valve 12 is not parallel to the central axis of the recovery solenoid valve 13.
[0050] Specifically, when the compression solenoid valve 12 and the recovery solenoid valve 13 are located in the same direction of the circumference of the cylinder body 11, the central axis of the compression solenoid valve 12 is parallel to the central axis of the recovery solenoid valve 13, and the angle between the central axis of the compression solenoid valve 12 and the central axis of the recovery solenoid valve 13 is 0°; when the compression solenoid valve 12 and the recovery solenoid valve 13 are arranged symmetrically along the circumference of the cylinder body 11, the central axis of the compression solenoid valve 12 is parallel to the central axis of the recovery solenoid valve 13, and the angle between the central axis of the compression solenoid valve 12 and the central axis of the recovery solenoid valve 13 is 180°.
[0051] The central axis of the compression solenoid valve 12 is not parallel to the central axis of the recovery solenoid valve 13, which means that the angle between the central axis of the compression solenoid valve 12 and the central axis of the recovery solenoid valve 13 can be an acute angle, an obtuse angle, or a right angle.
[0052] In the above embodiments, the central axis of the compression solenoid valve 12 is not parallel to the central axis of the recovery solenoid valve 13, which can reduce the interference between the compression solenoid valve 12 and the recovery solenoid valve 13 arranged in the circumference of the cylinder body 11 while meeting the welding conditions of the compression solenoid valve 12 and the recovery solenoid valve 13, thereby reducing the occupation of the shock absorber 10 to the wheel space.
[0053] Please refer to Figure 3 In some embodiments, the angle between the central axis of the compression solenoid valve 12 and the central axis of the recovery solenoid valve 13 is α, and α satisfies 120°≤α<180°.
[0054] Specifically, the angle between the central axis of the compression solenoid valve 12 and the central axis of the recovery solenoid valve 13 can be the angle between two intersecting lines, or the angle between two non-planar straight lines.
[0055] The angle α can be 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, etc. The specific value of the angle α can be determined by DMU checking and optimization analysis.
[0056] In one embodiment, the included angle α is 146.6°, the wheel-side space occupied by the shock absorber 10 is the smallest, and the height of the shock absorber 10 is reduced by 30 mm compared with the case where the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 are arranged in the same direction of the cylinder body 11.
[0057] In the above embodiment, when the included angle is within the above range, the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 are arranged in the cylinder body 11 with less interference in the circumferential direction, and the shock absorber 10 occupies less wheel-side space.
[0058] In some embodiments, the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 are in the same plane.
[0059] Specifically, the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 are in the same plane, that is, the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 are intersecting lines, and the distance from the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 to the bracket 14 is equal.
[0060] In other embodiments, the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 are in different planes, that is, the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 are skew lines, and the distance from the central axis of the compression electromagnetic valve 12 and the central axis of the recovery electromagnetic valve 13 to the bracket 14 is not equal.
[0061] The dimensions of the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11 can be the same or different.
[0062] In the above embodiment, the axial height of the shock absorber 10 can be designed according to the larger dimension of the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11, which reduces the axial height of the shock absorber 10 compared with the case where the axial height of the shock absorber 10 is designed according to the dimensions of the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11, thereby reducing the wheel-side space occupied by the shock absorber 10.
[0063] Please refer to Figure 2 In some embodiments, the minimum distance between the compression electromagnetic valve 12 and the bracket 14 is L1, and L1≥10 mm.
[0064] Specifically, the minimum distance between the compression electromagnetic valve 12 and the bracket 14 refers to the distance between the lowest point of the compression electromagnetic valve 12 in the axial direction of the cylinder body 11 and the bracket 14. When the cross section of the compression valve is circular, the minimum distance between the compression electromagnetic valve 12 and the bracket 14 can be the distance between the lower tangent point of the compression electromagnetic valve 12 in the axial direction of the cylinder body 11 and the bracket 14. When the cross section of the compression valve is square, the minimum distance between the compression electromagnetic valve 12 and the bracket 14 can be the distance between the lower surface of the compression electromagnetic valve 12 in the axial direction of the cylinder body 11 and the bracket 14.
[0065] The minimum distance L1 between the compression electromagnetic valve 12 and the bracket 14 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, etc. The minimum distance between the compression electromagnetic valve 12 and the bracket 14 can be designed according to the actual needs when the compression electromagnetic valve 12 is welded.
[0066] In the above embodiment, when the minimum distance between the compression electromagnetic valve 12 and the bracket 14 is within the above range, the axial size of the shock absorber 10 can be small while meeting the welding conditions of the compression electromagnetic valve 12, the volume of the shock absorber 10 is reduced, and the occupied space of the shock absorber 10 is reduced.
[0067] Please refer to Figure 2 In some embodiments, the minimum distance between the compression electromagnetic valve 12 and the bracket 14 is L1, the minimum distance between the recovery electromagnetic valve 13 and the bracket 14 is L2, and L2≥L1.
[0068] Specifically, the minimum distance between the recovery electromagnetic valve 13 and the bracket 14 refers to the distance between the lowest point of the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11 and the bracket 14. When the cross section of the recovery valve is circular, the minimum distance between the recovery electromagnetic valve 13 and the bracket 14 can be the distance between the lower tangent point of the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11 and the bracket 14. When the cross section of the recovery valve is square, the minimum distance between the recovery electromagnetic valve 13 and the bracket 14 can be the distance between the lower surface of the recovery electromagnetic valve 13 in the axial direction of the cylinder body 11 and the bracket 14.
[0069] When the minimum distance L1 between the compression electromagnetic valve 12 and the bracket 14 is 10 mm, the minimum distance L2 between the recovery electromagnetic valve 13 and the bracket 14 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, etc. The minimum distance between the recovery electromagnetic valve 13 and the bracket 14 can be designed according to the actual needs when the compression electromagnetic valve 12 and the recovery electromagnetic valve 13 are welded.
[0070] In the above embodiment, when the minimum distance between the restoring electromagnetic valve 13 and the bracket 14 meets the above condition, the axial size of the shock absorber 10 can be small while meeting the use requirements of the compression electromagnetic valve 12 and the restoring electromagnetic valve 13, the volume of the shock absorber 10 is reduced, and the occupied space of the shock absorber 10 is reduced.
[0071] Please refer to Figure 2 In some embodiments, the bracket 14 includes a mounting portion 15 and side plates 16 located on both sides of the mounting portion 15, the mounting portion 15 is welded with the cylinder body 11, and the side plates 16 extend away from the cylinder body 11.
[0072] Specifically, the mounting portion 15 and the side plates 16 can be integrally formed, and the side plates 16 away from the mounting portion 15 can be formed with through holes 17, and the shock absorber 10 and the control arm 20 can be detachably connected through the through holes 17, which is beneficial to improve the connection convenience of the shock absorber 10 and the control arm 20, and facilitate the maintenance and replacement of the shock absorber 10.
[0073] The distance between the two side plates 16 close to the mounting portion 15 can be greater than the distance between the two side plates 16 away from the mounting portion 15, so that the size of the mounting portion 15 is larger, which is convenient for welding the mounting portion 15 with the cylinder body 11, and at the same time, the distance between the two side plates 16 away from the mounting portion 15 is smaller, so that the bracket 14 and the control arm 20 are more stable.
[0074] In the above embodiment, it is convenient to design the mounting portion 15 according to the welding requirement of the bracket 14 and the cylinder body 11, and it is also convenient to design the side plates 16 according to the connection requirement of the bracket 14 and the control arm 20, which improves the applicability of the bracket 14.
