Problems solved by technology

[0002] The buffer block on the piston rod of the inverted front shock absorber is made of oil-resistant rubber. Due to the poor stability of the oil-resistant rubber, latex and fatigue are prone to occur, and the buffer function decreases. When latex or fatigue occurs, it is very difficult for the piston rod to continue downward. It is easy to hit the bottom, and the cost of oil-resistant rubber is relatively high

Embodiment Construction

[0008] exist figure 1 Among them, the present invention is a buffer device for an inverted front shock absorber, which includes a piston rod 1 and a damping cylinder 2, the piston rod 1 and the damping cylinder 2 are located in the shock absorber bushing of the shock absorber, and the piston rod 1 extends into the damping cylinder 2, a buffer block 3 is set on the piston rod. The buffer block 3 is made of PVC material. The tail of the damping cylinder 2 is provided with an extension body 4. The buffer block 3 moves up and down as the piston rod 1 extends into the extension body 4. A number of discharge holes 5 are distributed on the body 4. The discharge holes 5 are distributed along the moving direction of the buffer block 3. The buffer block 3 squeezes the hydraulic oil in the extension body 4, forcing the hydraulic oil to discharge through the discharge holes 5. Constitute the hydraulic buffer force, the discharge holes 5 are distributed from large to small, the discharge h...

Abstract

The invention discloses a cushioning device for an inverted front shock absorber, which comprises a piston rod (1) and a damping cylinder (2), wherein the piston rod (1) and the damping cylinder (2) are positioned in a shock absorbing bushing of a shock absorber; the piston rod (1) extends into the damping cylinder (2); and a bumping block (3) is sleeved on the piston rod (1). The cushioning device has the characteristics that: the tail part of the damping cylinder (2) is provided with an extension body (4); the bumping block (3) extends into the extension body (4) along with the piston rod (1) and moves up and down; the extension body (4) is provided with a plurality of discharge orifices (5) which are distributed along the moving direction of the bumping block (3); the bumping block (3) extrudes hydraulic oil in the extension body (4) to force the hydraulic oil to be discharged through the discharge orifices (5) to form hydraulic buffering force. The cushioning device not only can improve the buffering performance and avoid the phenomenon of running down, but also can realize graded buffering, and has good buffering effect.

Description

technical field [0001] The invention relates to a buffer device for an inverted front shock absorber Background technique [0002] The buffer block on the piston rod of the inverted front shock absorber is made of oil-resistant rubber. Due to the poor stability of the oil-resistant rubber, latex and fatigue are prone to occur, and the buffer function decreases. When latex or fatigue occurs, it is very difficult for the piston rod to continue downward. It is easy to hit the bottom, and the cost of oil-resistant rubber is relatively high. Contents of the invention [0003] The invention relates to a cushioning device for an inverted front shock absorber, which not only improves the cushioning performance and prevents bottoming, but also can realize graded cushioning and has good cushioning effect. [0004] The present invention adopts the following technical solutions: a buffer device for an inverted front shock absorber, which includes a piston rod and a damping cylinder, ...
