Damping type anti-bottoming shock absorber and three-wheeled motorcycle

Abstract

The invention discloses a damping type anti-bottoming shock absorber and a three-wheeled motorcycle, which include an inner cylinder, an outer cylinder and a shock-absorbing main spring. The anti-bottoming damping part is installed on the inner bottom of the outer cylinder toward the inner cylinder. When the inner cylinder is covered with the anti-bottoming damping part in the downward direction, there is a gap with the anti-bottoming damping part in the transverse direction; The outer cylinder, the inner cylinder is located above the piston and has a lubricating hole, the space in the outer cylinder opposite to the downward movement of the piston is filled with oil, and this space is connected to the inner cylinder; the shock absorber of the present invention is arranged at the bottom of the outer cylinder The anti-bottoming damping part, in the process of the inner cylinder going down and covering the anti-bottoming damping part, the hydraulic oil in the outer cylinder can only enter the inner cylinder through the gap, so as to form an effective compression damping force, which can effectively prevent bottoming out, At the same time, the hydraulic oil flows to the top of the piston through the lubricating hole under pressure, which is beneficial to the lubrication of the piston and improves the stress concentration of the piston.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and relates to a damping type anti-bottoming shock absorber and a three-wheeled motorcycle. Background technique [0002] Shock absorber is a necessary part of a motor vehicle. The structure affects the handling and comfort of the vehicle. Whether the performance is stable or not is directly related to the safety, reliability, comfort and handling of the vehicle. Existing shock absorbers generally include an inner cylinder, an outer cylinder, and a damping spring; the inner cylinder is generally sleeved on the outer cylinder through a piston, and the space opposite the outer cylinder and the piston is filled with hydraulic oil. When the inner cylinder reciprocates, the hydraulic oil Flow is formed in this space and in the inner cylinder, which plays the role of lubrication and limited liquid damping. In fact, because the diameter difference between the inner cylinder and the outer cylinder...

AI Technical Summary

Problems solved by technology

Existing shock absorbers generally include an inner cylinder, an outer cylinder, and a damping spring; the inner cylinder is generally sleeved on the outer cylinder through a piston, and the space opposite the outer cylinder and the piston is filled with hydraulic oil. When the inner cylinder reciprocates, the hydraulic oil Flow is formed in this space and in the inner cylinder, which plays the role of lubrication and limited liquid damping. In fact, because the diameter difference between the inner cylinder and the outer cylinder is not large, the damping effect is also extremely limited, and no effective compression damping force can be formed.

[0003] In the prior art, in order to save the overall cost of the three-wheeled motorcycle, one of the front shock absorbers adopts the aforementioned structure. The shock absorber of this structure has a better effect of restoring damping, but it cannot form effective compression damping. Therefore, in On slightly larger uneven roads, the shock absorber will bottom out, seriously affecting the handling, comfort, safety and reliability of the vehicle
