Abstract

The invention discloses a thread drive based shock absorber which comprises a shock absorption supporting rod and a threaded supporting rod. A gasket disc is mounted in the threaded supporting rod. The shock absorption supporting rod is mounted in the threaded supporting rod and provided with a spring mounting base. A fastener is mounted on the shock absorption supporting rod and used for fastening the spring mounting base and the shock absorption supporting rod. An upper pressing disc and a lower pressing disc are mounted on the threaded supporting rod through threads. A shock absorption spring is mounted between the lower pressing disc and the spring mounting base. A first connecting piece is mounted in a first unthreaded hole of the shock absorption supporting rod, and a second connecting piece is mounted in a second unthreaded hole of the threaded supporting rod. During use, the upper pressing disc and the lower pressing disc are in threaded connection together and are mounted on a cylindrical threaded rod of the threaded supporting rod through the threads, the shock absorption spring is mounted between the spring mounting base and the lower pressing disc, and therefore the pre-tightening force of the shock absorption spring can be adjusted by adjusting the lower pressing disc, and adjustment is facilitated.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a thread drive-based shock absorber. Background technique [0002] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. The preload of the shock absorber spring on the current shock absorber is inconvenient to adjust, so further improvement is needed. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a shock absorber based on thread transm...
