Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 2-8, a shock absorber 100 is provided in accordance with the present invention. The shock absorber 100 is used in a vehicle suspension system to absorb road impacts and attenuate suspension and body vibrations. As shown in fig. 2, the shock absorber 100 of the present invention includes a damper 10, a spring 20 sleeved on an outer circumference of the damper 10, a dust cover 30, a spring tray 40 fixed on the damper 10, an oil seal end cover 60, an upper mounting seat 70, and a bearing 80. In this embodiment, the spring 20 is an S-shaped lateral force spring. The damper 10 is a fixed member, the spring tray 40 is fixed to the outer circumferential surface of the damper 10 by welding, and the spring tray 40 is used for supporting the spring 20 sleeved on the damper 10. The oil seal end cap 60 is provided at the end of the damper 10, and the dust cover 30 is fixed to the oil seal end cap 60. The upper end of the spring 20 abuts the dust cover 30, and the lower end abuts the spring tray 40. Specifically, the oil seal end cover 60 is interference-fitted at the end of the damper 10, the lower end of the dust cover 30 is clamped on the oil seal end cover 60, the upper end of the dust cover 30 is provided with a bearing 80, and the dust cover 30 is fixedly connected with the upper mounting support 70 through the bearing 80.
As shown in fig. 3 and 4, in the damper 100 according to the present invention, the dynamic rubber ring 50 abutting against the spring 20 is further provided on the spring tray 40, and the dynamic rubber ring 50 is provided to reduce the transmission of vibration of the spring 20 and the generation of noise. The dynamic rubber ring 50 arranged in the spring tray 40 can ensure that the lower end part of the spring 20 is stably arranged in the spring tray 40, and the spring 20 is prevented from sliding out from the side surface of the spring tray 40 due to vibration during the running process of the vehicle.
Specifically, as shown in fig. 4, the position where the starting point of the spring 20 is located on the spring tray 40 is an initial position 101, and the position where the spring 20 is separated from the dynamic rubber ring 50 is an end position 102. The spring tray 40 disposed on the outer circumference of the damper 10 is mainly used to support the lower end of the spring 20 located above the spring tray from the starting point 21 to the spring 20 to rotate about 0.6 turn. In the present embodiment, the spring tray 40 holds the spring 20 at a distance from 0 ° at the initial position 101 to a final position 102 after rotating 230 ° around the center of the spring 20. Thus, the dynamic rubber ring 50 provided on the spring tray 40 extends from the initial position 101 to the end position 102 around the damper 10. The dynamic rubber ring 50 can cover the entire distance of the springs 20 held by the spring tray 40.
As shown in fig. 3 and 6, the spring tray 40 is spirally raised on the damper 10. That is, the lift of the spring tray 40 is a horizontal height change of the spring tray 40 on the damper 10. As can be seen from fig. 6, the spring plate 40 has a gradually increasing lift from the initial position 101 to the end position 102. The lift of the spring tray 40 is gradually increased, so that the spring tray 40 is increased along with the spiral rising characteristic of the spring 20, thereby ensuring that the lift of the spring tray 40 and the lift of the spring 20 can be matched with each other.
As shown in fig. 3 and 8, the dynamic rubber ring 50 has a gradually increasing lift from an initial position 101 to a final position 102. The lift of the dynamic rubber ring 50 is also a change in the level of the dynamic rubber ring 50 on the damper 10. As can be seen from fig. 8, the lift of the dynamic rubber ring 50 is gradually increased, so that the dynamic rubber ring 50 is also increased along with the spiral rising characteristic of the spring 20, thereby ensuring that the lift of the dynamic rubber ring 50 and the lift of the spring 20 can be matched with each other.
In the shock absorber 100 provided by the invention, the lift ranges of the spring tray 40 and the dynamic rubber ring 50 are gradually increased along with the lift range of the spring 20, so that the spring tray 40 and the dynamic rubber ring 50 always surround the spring 20 in the driving process of the whole vehicle, and a better support is provided for the spring 20, thereby avoiding the generation of a gap between the spring 20 and the dynamic rubber ring 50 due to unmatched lift ranges, so that the abrasion of the coating of the spring 20 caused by the sand and stone clamped in the gap in the driving process is avoided, and the problem of reducing the service life of the spring 20 is solved.
Further, referring to fig. 6 and 8, the present invention provides a shock absorber 100 in which the lift of the dynamic rubber ring 50 is greater than that of the spring plate 40. That is, the amount of increase in the height of the dynamic rubber ring 50 with respect to the damper 10 is larger than the amount of increase in the height of the spring tray 40 with respect to the damper 10. Just as the lift of the dynamic rubber ring 50 is larger than that of the spring tray 40, the lower end of the spring 20 can be always tightly attached to the dynamic rubber ring 50 in the whole vehicle running process.
Further, as shown in fig. 4, the shock absorber 100 of the present invention is provided in which the spring tray 40 and the damper 10 are eccentrically disposed in the width direction (Y direction) of the vehicle body. The spring tray 40 is eccentrically disposed from the damper 10 in the vehicle width direction (Y direction), and the center of the spring tray 40 and the center of the damper 10 have an L distance therebetween, which may provide a part of the lateral force to the shock absorber 100. Specifically, the center of the spring tray 40 is eccentric toward the outside of the vehicle body in the width direction (Y direction) of the vehicle body, so that the lateral force generated due to the eccentric arrangement can be offset from the lateral force generated during the running of the vehicle, thereby reducing the influence of the lateral force generated by the vehicle on the shock absorber 100.
Further, as shown in fig. 7, the present invention provides a damper 100, in which the dynamic rubber ring 50 is provided with a groove 51 on an abutting surface with the spring 20, on which the spring 20 can be placed, and a first avoidance groove 52 communicating with the groove 51 is provided at an initial position 101. The groove 51 is arranged so that the lower end of the spring 20 can be better embedded in the dynamic rubber ring 50, and the stability of the spring 20 on the spring tray 40 is ensured. The first avoiding groove 52 is arranged at the initial position 101, so that the dynamic rubber ring 50 can be prevented from being cracked due to the large stress of the starting point 21 of the spring 20 when the spring is stressed, and the service life of the dynamic rubber ring 50 is ensured. Correspondingly, as shown in fig. 5, a second avoiding groove 41 is also provided at the initial position 101 of the spring tray 40, so that the first avoiding groove 52 of the dynamic rubber ring 50 can be embedded into the second avoiding groove 41, on one hand, the depth of the first avoiding groove 51 can be ensured, and the end of the dynamic rubber ring 50 is prevented from being crushed by the end of the spring 20; on the other hand, the end of the dynamic rubber ring 50 can be fixed in the spring tray 40, which plays a role in fixing and supporting the dynamic rubber ring 50.
Specifically, as shown in fig. 5 and 7, a first through hole 53 is further provided in the first avoiding groove 52 of the dynamic rubber ring 50, and a second through hole 43 communicating with the first through hole 53 is also provided in the second avoiding groove 41 of the spring tray 40. The arrangement of the first through hole 53 and the second through hole 43 can meet the requirements of flowing water and sand leakage at the starting point 21 of the spring 20, and plays a role in protecting the spring 20.
Further, as shown in fig. 5, the spring tray 40 is further provided with a first stopper 42 extending toward the center of the damper 10 at a terminating position 102, and the dynamic rubber ring 50 is provided with a first stopper groove 54 corresponding to the first stopper 42 at the terminating position 102. The first position-limiting portion 42 and the first position-limiting groove 54 of the spring tray 40 are engaged with each other, so that the end of the dynamic rubber ring 50 is fixed to the spring tray 40. The second escape groove 41 and the first stopper 42 of the spring tray 40 serve to fix the initial end and the final end of the dynamic rubber ring 50, respectively.
Specifically, as shown in fig. 5 and 7, an outer stopper 45 is provided toward the center on the outer circumference of the spring tray 40, and an outer stopper groove 55 is also provided on the outer circumference of the dynamic rubber ring 50 corresponding to the outer stopper 45. The outer limit part 45 on the spring tray 40 and the outer limit groove 55 on the dynamic rubber ring 50 are mutually clamped and embedded, so that the positioning and fixing effects of the outer side of the dynamic rubber ring 50 are realized. And the center of the spring tray 40 is provided with an inner limiting bulge 46, and the limiting bulge 46 is embedded with the inner circumferential surface of the dynamic rubber ring 50, so that the positioning and fixing functions of the inner side of the dynamic rubber ring 50 are realized. And a plurality of sand leakage holes 47 are arranged on the outer circumference of the spring tray 40, a plurality of corresponding sand leakage holes 56 are also arranged on the dynamic rubber ring 50, sand or running water falling on the spring tray 40 can be discharged from the sand leakage holes 56 in the running process of the vehicle, and the influence and the erosion of the sand or the running water on the end part of the spring 20 are avoided. Meanwhile, lightening holes 44 are further formed in the region, where the dynamic rubber ring 50 is not arranged, of the spring tray 40, on one hand, the effect of lightening the whole weight of the spring tray 40 can be achieved, on the other hand, the effects of sand leakage and water leakage can be achieved, and the spring 20 is guaranteed not to be collided with sand and stones on the spring tray 40.
