Problems solved by technology

Existing shock absorbers generally include damping components and shock absorbing springs; for the shock absorbers of this structure, more are independently applied to motorcycles, and when used in front shock absorbers, the overall length is longer, and the shock absorbing springs are The cylindrical spring covers the piston rod; due to its length, the cylindrical spring will deviate from the center line, causing collision and friction between the piston rod and the spring, resulting in damage to the spring and the piston rod, affecting normal use; The noise will affect the use of motorcycles and reduce the comfort and safety of use

Abstract

The invention discloses a low-noise mild type damping assembly which comprises a damping spring and a damper module. The damper module comprises a damping drum and a piston module, the piston module comprises a piston and a piston rod, the damping spring sleeves the piston rod, the middle of the piston rod located between the damping spring and the piston rod is sleeved with a guide sleeve, and the guide sleeve is axially limited on the piston rod. The middle of the piston rod is provided with the guide sleeve structure and is just the part where the spring is easily deviated from the center line to be deformed, the collision and friction of the spring and the piston rod can be avoided in use, the piston rod and the spring are protected, the smoothness of relative motion of the piston rod and the spring is guaranteed, the noise of a damper is reduced, and the comfort and smoothness are improved.

Description

Technical field [0001] The invention relates to a motor vehicle component, in particular to a low-noise and gentle shock-absorbing assembly. Background technique [0002] Shock absorber is a necessary component of motor vehicle. The structure affects the controllability and comfort of the vehicle, and the stability and reliability of the performance is directly related to the safety, reliability, comfort and handling of the vehicle. Existing shock absorbers generally include damping components and shock-absorbing springs; for shock absorbers with this structure, they are mostly independently applied to motorcycles. When used in front shock absorbers, the overall length is longer. The shock-absorbing spring is The cylindrical spring is sheathed on the piston rod; due to its length, the cylindrical spring will deviate from the center line, resulting in collision and friction between the piston rod and the spring, resulting in damage to the spring and the piston rod, affecting norma...
