Description

Technical Field

[0001] This utility model relates to a vibration damper assembly, and more particularly to a high-strength vibration damper assembly. Background Technology

[0002] With the implementation of the dual-credit policy for passenger vehicles and increased construction of charging infrastructure, the transformation towards new energy vehicles has accelerated significantly, making it a convergence point of the energy revolution and the intelligent revolution. Simultaneously, people's demands for the lifespan of automobiles and other transportation vehicles are constantly increasing, and some OEMs have already introduced lifetime engine warranties. As a standard component of new energy vehicles, the lifespan requirement for shock absorbers extends throughout their entire lifecycle. Traditional shock absorber drive hubs and drive shafts are separate structures, and the shaft is often fixed on only one side, making them prone to damage and affecting their overall lifespan. Summary of the Invention

[0003] This invention addresses the technical problem that existing shock absorber drive hubs and drive shafts are mostly separate structures with single-sided fixation, which makes it difficult to meet the lifespan requirements of shock absorbers in the current rapid development of new energy vehicles. It provides a high-strength shock absorber assembly that is reliable in connection, has good vibration reduction effect, simple in structure, and long in service life.

[0004] Therefore, the technical solution of this utility model is a high-strength shock absorber assembly, which includes a transmission disc, shock absorber discs on both sides of the transmission disc, a window on the transmission disc, a shock absorber spring inside the window, and the shock absorber discs on both sides of the shock absorber spring; the transmission disc has mounting holes for connecting to an engine; the transmission disc has a toothed hole in the middle, and a disc hub inside the toothed hole; the shock absorber disc and the disc hub are fixed together with a connecting disc by rivets; a friction pad is provided between the shock absorber disc and the transmission disc, and a friction washer is provided between the friction pad and the transmission disc; a friction disc and a conical spring are provided between the friction pad on the side away from the connecting disc and the shock absorber disc, and the conical spring is located between the shock absorber disc and the friction pad.

[0005] Preferably, the outer edge of the transmission disk is hexagonal, and there are six mounting holes, which are evenly distributed on each corner of the hexagonal transmission disk.

[0006] Preferably, the damping spring is a large spring with a small spring inside it.

[0007] Preferably, the hub and the connecting disc are positioned by a locating pin, and eight rivets are used to connect the damping disc, the hub, and the connecting disc, which are evenly distributed along the circumference to achieve backlash-free transmission.

[0008] Preferably, the transmission disc has six windows, arranged in an alternating pattern of three small and three large windows.

[0009] Preferably, the outer edge of the hub is provided with external teeth corresponding to the tooth holes of the transmission disc, which are used to limit the torsional angle of the shock absorber.

[0010] The beneficial effects of this utility model are:

[0011] (1) The transmission disc windows are arranged in three small and three large alternating arrangements, and damping springs are installed in the windows to realize two-stage stiffness transmission, which can better mitigate the impact force.

[0012] (2) Friction pads, friction washers, friction discs and conical springs are provided between the transmission disc and the damping disc, which can better dissipate vibration energy, suppress the amplitude of torsional resonance response, and attenuate the transient torsional vibration caused by impact, which can effectively extend the service life of the damper.

[0013] (3) In this application, the traditional internal spline of the disc hub is eliminated. It is connected by rivets and positioning pins to achieve backlash-free transmission, which reduces noise, increases the strength of the shock absorber, and further extends the service life.

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] like Figure 1-8 As shown, a high-strength shock absorber assembly includes a transmission disc 1, with shock absorber discs 2 on both sides of the transmission disc 1. The transmission disc 2 has a window, and a shock absorber spring 3 is installed inside the window. The shock absorber spring 3 is a large spring with a smaller spring inside. The shock absorber discs 2 cover both sides of the shock absorber spring 3. The transmission disc 1 has mounting holes for connecting to the engine. A toothed hole is located in the middle of the transmission disc 1, and a disc hub 4 is installed inside the toothed hole. The shock absorber discs 2 and the disc hub 4 are fixed together with a connecting disc 5 by rivets 6, which are evenly distributed circumferentially, totaling eight rivets. A friction pad 7 is provided between the shock absorber disc 2 and the transmission disc 1, and a friction washer 8 is provided between the friction pad 7 and the transmission disc 1. A friction disc 9 and a conical spring 10 are located between the friction pad 7 on the side away from the connecting disc 5 and the shock absorber disc 2. The conical spring 10 is located between the shock absorber disc 2 and the friction disc 9.

[0026] The outer edge of the transmission disc 1 is hexagonal, with six mounting holes evenly distributed at each corner. The hub 4 has two blind locating pin holes 2.2, and the connecting disc 5 has two through locating pin holes 5.1. The hub 2 and connecting disc 5 are positioned by these two locating pins. Eight rivets connect the damping disc 2, hub 4, and connecting disc 5, evenly distributed circumferentially to achieve backlash-free transmission. The transmission disc 1 has six windows, with three small windows 1.2 and three large windows 1.1 arranged alternately. Damping springs 3, with large springs surrounding small springs, are installed inside the windows to achieve two-stage stiffness transmission, better mitigating impact forces.

[0027] The connecting plate 5 is also equipped with a sub-port, keyway, and threaded hole, which can be used for positioning through the sub-port and keyway, and can be connected to the generator or other mechanisms through the threaded hole to achieve backlash-free transmission.

[0028] The outer edge of the hub 4 has external teeth corresponding to the toothed holes of the transmission disc 1, used to limit the torsional angle of the damper. Friction pads 7, friction washers 8, friction discs 9, and conical springs 10 are provided between the transmission disc 1 and the damping disc 2, which can better dissipate vibration energy, suppress the amplitude of torsional resonance response, and attenuate transient torsional vibration caused by impact, effectively extending the service life of the damper. In this application, the hub 4 eliminates the traditional internal spline and is connected by rivets 6 and locating pins to achieve backlash-free transmission, reducing noise, increasing the strength of the damper, and further extending its service life.

[0029] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
