Description

Front overhang damping device

Technical Field

The utility model relates to a front suspension of a vehicle, in particular to a front suspension damping device.

Background

A suspension is a general term for all force-transmitting connections between a vehicle frame (or a load-bearing vehicle body) and an axle (or a wheel). The suspension mainly comprises a front suspension and a rear suspension, wherein the front suspension is connected with a front axle of a vehicle body as the name implies. In order to isolate and reduce the adverse effect on the cab caused by various vibrations from an engine and the ground during driving and play a role in supporting the cab so as to improve the comfort and the safety of drivers and passengers, a damping block is arranged in the front suspension.

Traditional damper only comprises ordinary rubber cushion, and the shock attenuation effect does not reach ideal state, and in the in-service use process, the front overhang vibrations are still great, hardly eliminates the influence that the automobile body vibrations brought, and the shock attenuation shock resistance effect is relatively poor. And the traditional damping piece has multiple specification types, the damping piece with different length specifications can be used in the front overhang with different specifications, the longer the damping piece with the longer length has the larger radial value, the shorter the damping piece with the shorter length has the smaller radial value, and the damping piece with the shorter length needs to be specially configured if the radial value is required to be larger, so the use flexibility is poor.
