Description

Technical Field

[0001] This utility model relates to a shock absorption structure for a drive half-bridge, belonging to the field of vehicle shock absorption technology. Background Technology

[0002] The drive axle is an important component of a vehicle's power transmission system. Its main function is to transmit power from the engine or electric motor to the wheels, thereby propelling the vehicle forward. The drive axle is typically located at the end of the transmission system, where it alters the speed and torque from the transmission and transmits them to the drive wheels.

[0003] Commonly used drive axles are divided into integral drive axles (i.e., full drive axles) and split drive axles (i.e., half drive axles). Half drive axles are suitable for vehicles with higher cost and weight requirements, such as mining vehicles, and typically only drive one side of the wheels. However, when mining vehicles operate in complex terrain, vibrations from the half drive axles often occur. Currently, existing technologies only provide damping mechanisms designed for full drive axles; due to the limited use of half drive axle structures, no effective solution to the vibration problem has yet emerged.

[0004] Therefore, there is an urgent need to find a vibration damping device that can be applied to drive half-axles to optimize the vibration problem generated by mining vehicles and other equipment during operation. Utility Model Content

[0005] To solve the above problems, this utility model provides a vibration damping structure for a drive half-bridge, comprising:

[0006] The brake connecting plate has a central through hole;

[0007] The shock absorber includes two fixed blocks distributed vertically and two guide shafts connecting the two fixed blocks. A spring and a sliding bushing are sequentially fitted onto the guide shafts from top to bottom. One end of the spring is connected to the sliding bushing, and the other end is connected to the upper fixed block. The sliding bushing is connected to the brake connecting plate.

[0008] The wheel-side motor is fixed to the center through hole and connected to the tire.

[0009] Furthermore, the upper fixed block is connected to a downwardly positioned oil-gas spring, the bottom of which is fixedly connected to the brake connecting plate via an oil-gas spring bracket.

[0010] Furthermore, the top of the brake connecting plate is connected to a limiting block via a limiting block fixing seat, and the limiting block is located below the upper fixing block.

[0011] Furthermore, the limiting block has a trapezoidal block structure.

[0012] Furthermore, a linear sliding bearing liner is provided inside the sliding bushing.

[0013] Furthermore, a buffer washer is provided between the sliding bushing and the fixed block below, and the buffer washer is sleeved on the guide shaft.

[0014] Furthermore, the end of the guide shaft connected to the upper fixing block is provided with a thread, and the connection between the spring and the upper fixing block is provided with a round nut and a compression washer.

[0015] Furthermore, the brake connecting plate is provided with wing plates on both sides, and two sliding bushings are fixedly connected by the wing plates on both sides.

[0016] The beneficial effects of this utility model are:

[0017] This invention forms a basic shock-absorbing frame by setting a fixed block and a guide shaft, and forms a shock-absorbing module by combining a spring, a sliding bushing, and a buffer washer. This constitutes a shock-absorbing mechanism specifically designed for driving the half-axle and connected near the wheels and brakes, which can adapt to the vibrations generated by the vehicle during driving. At the same time, a limit block is added to limit the amplitude of vehicle vibration, which improves the driving experience to a certain extent. In addition, the preload of the spring can be adjusted by using a round nut to adjust the initial posture of the vehicle. Attached Figure Description

[0024] Example 1

[0025] This utility model provides a vibration damping structure for a drive half-bridge, comprising:

[0026] Brake connecting plate 1 has a central through hole;

[0027] The shock absorber includes two fixed blocks distributed vertically and two guide shafts connecting the two fixed blocks. The upper fixed block is the first fixed block 4, and the lower fixed block is the second fixed block 5. The guide shaft 3 is fitted with a spring 6 and a sliding bushing 2 from top to bottom. One end of the spring 6 is connected to the sliding bushing 2, and the other end is connected to the upper fixed block (i.e., the first fixed block 4). The sliding bushing 2 is connected to the brake connecting plate 1. A linear sliding bearing pad 13 is provided inside the sliding bushing 2 to reduce sliding resistance and wear. A buffer washer is provided between the sliding bushing 2 and the lower fixed block. The buffer washer is fitted on the guide shaft to reduce friction between the sliding bushing and the lower fixed block and to provide a certain buffering effect.

[0028] The wheel-side motor is fixed to the center through hole and connected to the tire.

[0029] Furthermore, the upper fixed block (i.e., the first fixed block 4) is connected to a downwardly positioned oil-gas spring 10. The bottom of the oil-gas spring 10 is fixedly connected to the brake connecting plate through an oil-gas spring bracket 9. The oil-gas spring 10 can share some of the vibration.

[0030] Furthermore, the top of the brake connecting plate 1 is connected to a limiting block 12 via a limiting block fixing seat 11, and the limiting block 12 is located below the upper fixing block (i.e., the first fixing block 4); preferably, the limiting block 12 is a trapezoidal block structure.

[0031] Furthermore, the guide shaft 3 is threaded at one end connected to the upper fixing block (i.e., the first fixing block 4), and a round nut 14 and a compression washer 8 are provided at the connection between the spring 6 and the upper fixing block (i.e., the first fixing block 4), which can be used to adjust the preload of the spring 6, thereby changing the initial attitude of the vehicle.

[0032] Furthermore, the brake connecting plate 1 is provided with wing plates on both sides, and two sliding bushings 2 are fixedly connected by the wing plates on both sides to improve structural stability and balance.

[0033] When the vehicle encounters bumpy road sections during operation, the brake connecting plate 1 vibrates along with the wheels and drive half-axle, causing the sliding bushing to float up and down along the guide shaft 3. Under the action of the spring 6 and the buffer washer 7, the vibration effect can be effectively weakened, thus playing a shock absorption role. The setting of the limit block 12 can limit the maximum deformation of the spring 6 and prevent other components from colliding with the first fixed block 4.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
