Hydraulic motorcycle shock absorber and shock absorption method thereof

Abstract

The invention discloses a hydraulic motorcycle shock absorber and a shock absorption method of the hydraulic motorcycle shock absorber. The hydraulic motorcycle shock absorber comprises a movable rodand a sleeve which are arranged coaxially, one end of the sleeve is closed, the movable rod and the closed end of the sleeve are respectively fixedly connected with a connecting piece, the movable rodis fixedly connected with a connecting rod and a plurality of push rods, the connecting rod is fixedly connected with a first piston rod, and the first piston rod extends into the sleeve. A pluralityof channels which correspond to the push rods one by one and extend in the axial direction are formed in the wall of the sleeve, second piston rods are arranged in the channels in a sliding mode, thechannels communicate with a cavity, the cavity communicates with an inner cavity of the sleeve, and the cavity is filled with pressure-bearing liquid. According to the hydraulic motorcycle shock absorber and the shock absorption method of the hydraulic motorcycle shock absorber, the stroke of the first piston rod is effectively reduced by adopting a double-hydraulic mode, so that the driving comfort is improved.

Description

technical field [0001] The invention relates to the field of motorcycle shock absorbers, in particular to a hydraulic motorcycle shock absorber and a shock absorbing method thereof. 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. [0003] Hydraulic pressure is a commonly used buffer structure in existing motorcycle shock absorbers, but most of the prior art adopts a direct buffer method, that is, the piston rod is simply buffered by a pressurized liquid, and the stroke of the piston rod is relatively large. The rebound force is also larger, resulting in a decrease in driving comfort. Contents of the invention [0004] In view of this...
