Problems solved by technology

[0002] At present, the existing rear shock absorber for vehicles mainly relies on the rear shock absorbing spring and the cushion pad installed on the top of the piston rod. Without any buffer device, once the piston is under a large pressure, it will cause a violent impact between the piston and the bottom of the inner wall of the outer cylinder, affecting the overall shock absorption effect of the rear shock absorber

Embodiment Construction

[0014] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0015] Such as figure 1 A rear shock absorber shown has an outer cylinder welding part 6, a piston 12 and a piston rod 7 connected to the piston 12 are installed in the inner cavity of the outer cylinder welding part 6, and the inner cavity of the outer cylinder welding part 6 An elastic buffer block 14 is arranged in the middle, and the buffer block 14 is located between the piston 12 and the bottom of the outer cylinder welding part 6 . There is a U-shaped groove in the center of the buffer block 14, and the buffer block 14 is olive-shaped. The diameter of the middle part of the buffer block 14 is greater than the diameter of both ends of the buffer block 14, and the diamete...

Abstract

The invention relates to a rear vibration isolator. The rear shock absorber is provided with an outer cylinder welding piece, a piston and a piston rod connected with the piston are arranged in the cavity of the outer cylinder welding piece, a buffer block with elasticity is arranged in the cavity of the outer cylinder welding piece, and the buffer block is positioned between the piston and the bottom of the outer cylinder welding piece. The center of the buffer block is provided with a U-shaped groove, and the buffer block is olivary. The end diameter of one end of the buffer block contactedwith the piston is smaller than the end diameter of the other end of the buffer block contacted with the bottom of the outer cylinder welding piece. The buffer block is arranged between the piston and the outer cylinder welding piece, the piston impacts the buffer block when the rear vibration isolator absorbs shock, and the buffer block rubs the outer wall of the outer cylinder welding piece to reduce the shock absorption effect and prolong the service life of the piston, so the integral shock absorption effect of the rear vibration isolator is improved and the service life of the rear shockabsorber is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a rear shock absorber. Background technique [0002] At present, the existing rear shock absorber for vehicles mainly relies on the rear shock absorbing spring and the cushion pad installed on the top of the piston rod. Without any cushioning device, once the piston is under a large pressure, it will cause a violent collision between the piston and the bottom of the inner wall of the outer cylinder, affecting the overall shock absorption effect of the rear shock absorber. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a rear shock absorber that can more effectively absorb shocks during severe vibrations. [0004] The technical solution adopted by the present invention to solve the technical problem is: a rear shock absorber, which has an outer cylinder weldm...
