as shown in fig. 1, 2 and 3, the present invention provides a vehicle damper 1, including an outer cylinder 2, an inner cylinder 3, an inner shaft 4, a first vibration damping portion 5, a second vibration damping portion 6 and a clamping portion 7, wherein the outer cylinder 2 is sleeved on the inner cylinder 3, the inner shaft 4 is disposed in the inner cylinder 3, one end of the inner shaft 4 abuts against the outer cylinder 2, the other end of the inner shaft 4 abuts against the inner cylinder 3, the first vibration damping portion 5 is clamped between the outer cylinder 2 and the inner cylinder 3, the first vibration damping portion 5 is sleeved on the end of the inner shaft 4 abutting against the outer cylinder 2, the second vibration damping portion 6 is clamped between the inner cylinder 3 and the inner shaft 4, one end of the second vibration damping portion 6 abuts against the inner cylinder 3, the other end of the second vibration damping portion 6 abuts against the inner shaft 4, and the inner cylinder 3 and the outer cylinder 2 are connected by the clamping portion.
In this embodiment, the first vibration reduction part 5 includes a first magnetic ring 50, a first damping spring 52 and a second magnetic ring 54, wherein the first damping spring 52 is interposed between the first magnetic ring 50 and the second magnetic ring 54. And the first damping spring 52 is a high manganese-based damping spring, which has both the mechanical properties of low-carbon steel and the damping effect of rubber, and the damping effect is more obvious when the deformation is larger.
Specifically, the outer diameters of the first magnetic ring 50 and the second magnetic ring 54 are equal to the diameter of the inner shaft 4, the inner diameters of the first magnetic ring 50 and the second magnetic ring 54 are slightly larger than the diameter of the inner shaft 4, and the first magnetic ring 50, the first damping spring 52 and the second magnetic ring 54 are in clearance fit with the inner shaft 4 and can be sleeved on the inner shaft 4. In addition, the first magnetic ring 50 and the second magnetic ring 54 repel each other when they are close together.
In the present embodiment, the second vibration damping portion 6 includes a first magnet 60, a second damper spring 62, and a second magnet 64, and the second damper spring 62 is interposed between the first magnet 60 and the second magnet 64. And the second damping spring 62 is a high manganese-based damping spring, which has both the mechanical properties of low-carbon steel and the damping effect of rubber, and the damping effect is more obvious when the deformation is larger.
Specifically, the outer diameters of the first magnet 60 and the second magnet 64 are equal to the diameter of the inner shaft 4. In addition, the first magnet 60 and the second magnet 64 repel each other when they are close together.
In this embodiment, the clamping portion 7 includes a limiting groove 70 and a limiting block 72, wherein the limiting groove 70 is disposed on the outer cylinder 2, and the limiting block 72 is disposed on the inner cylinder 3.
Specifically, the limiting block 72 is clamped in the limiting groove 70, and two ends of the limiting groove 70 correspond to the maximum compression stroke and the maximum extension stroke of the shock absorber, respectively.
In the present embodiment, the free end of the outer cylinder 2 and the free end of the inner cylinder 3 are provided with mounting support rings. Wherein the support ring 8 is connected with the free end of the outer cylinder 2 and the free end of the inner cylinder 3 through bolts.
The working principle of the vehicle shock absorber 1 provided by the embodiment is as follows: when the vehicle shock absorber 1 starts to compress, the damping action starts, the relative movement between the outer tube 2 and the inner tube 3 starts, and the first damping spring 52 and the second damping spring 62 start to compress, and the stiffness of the vehicle shock absorber 1 is approximately linearly changed. When the vehicle shock absorber 1 continues to be compressed, and the outer cylinder 2 and the inner cylinder 3 move relatively to each other to reach a certain distance, along with the fact that the first damping spring 52 and the second damping spring 62 continue to be compressed, the distance between the first magnetic ring 50 and the second magnetic ring 54 is closer and closer, the repulsive force between the first magnetic ring 50 and the second magnetic ring 54 is larger and larger, and similarly, the distance between the first magnet 60 and the second magnet 64 is closer and closer, the repulsive force between the first magnet 60 and the second magnet 64 is larger and larger, so that the rigidity of the vehicle shock absorber 1 is larger and larger. While the rigidities of the first and second damping springs 52 and 62 are maintained substantially constant, the rigidities of the first and second magnetic rings 50 and 54, and the first and second magnets 60 and 64 exhibit non-linearity, so that the rigidity of the vehicle shock absorber 1 as a whole exhibits non-linear variation. The rigidity of the vehicle shock absorber 1 is maximized when it is in a fully compressed state, and is minimized when the vehicle shock absorber 1 is in a fully relaxed state without being subjected to a force. In conclusion, the vehicle shock absorber 1 can realize the linear change of the rigidity, and when the vehicle shock absorber 1 encounters strong impact, the vehicle shock absorber can provide a good protection effect for the spring and the vehicle shock absorber, so that the service life of the vehicle shock absorber 1 is effectively prolonged.
The beneficial effect of the automobile shock absorber that this embodiment provided does: the vehicle shock absorber provided by the invention has the advantages that the first shock absorbing part and the second shock absorbing part which are installed in parallel are used, so that the rigidity of the vehicle shock absorber at the initial stage of displacement is approximately linear, when the displacement is gradually increased, the first shock absorbing part and the second shock absorbing part are close to each other, the repulsive force of the first shock absorbing part and the second shock absorbing part is gradually increased, the nonlinear characteristic of the rigidity of the vehicle shock absorber is gradually enhanced, when the vehicle shock absorber is subjected to strong impact, a good protection effect can be provided for a spring and the vehicle shock absorber, and the service life of the vehicle shock absorber is. In addition, the vehicle shock absorber uses the damping spring, and has no pollution to the external environment
Although the present invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
