Comfortable damping anti-bottoming shock absorber and three-wheeled motorcycle

Abstract

The invention discloses a comfortable damping anti-bottoming shock absorber and a three-wheeled motorcycle, which include an inner cylinder, an outer cylinder and a main shock-absorbing spring. The main damping spring is a sudden change pitch spring composed of a long pitch section and a short pitch section, and also includes an anti-bottoming damping member installed on the inner bottom of the outer cylinder facing the inner cylinder, and the inner cylinder goes down and is covered with an anti-bottoming When the damper is used, there is a gap in the lateral direction with the anti-bottoming damper; the inner cylinder is sleeved on the outer cylinder through the piston, and the inner cylinder is located above the piston. It is filled with oil, and the space is connected to the inner cylinder; the present invention adopts abrupt pitch springs and anti-bottoming damping parts, and the damping force formed by the anti-bottoming damping parts works together with the sudden pitch springs to avoid When driving, the shock absorber bottoms out, improving driving comfort and ensuring controllability.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and relates to a comfort-shaped damping anti-bottom shock absorber and a three-wheeled motorcycle. Background technique [0002] The shock absorber is a necessary part of the motor vehicle. The structure affects the handling and comfort of the whole vehicle, and whether the performance is stable and reliable is directly related to the safety, reliability, comfort and handling of the whole vehicle. Existing shock absorbers generally include an inner cylinder, an outer cylinder and a shock-absorbing spring; the inner cylinder is generally sleeved on the outer cylinder through the piston, and the space opposite the outer cylinder and the piston downward is filled with 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 diameters of the inner cylinder and the outer cylinder are not much diff...

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
