Abstract
The invention discloses a kind of protection type piston rod of shock absorber for vehicles; including piston bar body; the piston bar body is equipped with multistage external screw thread; pre- protection ring is threaded on the external screw thread; shape is placed on the piston rod outer body face the pre- protection ring in a ring; protrusion is provided with rubber cushion block on the pre- protection ring upper and lower end face; also protrusion is provided with tapered thorn on the pre- protection ring exterior annular face; the tapered thorn crowning is cone body, and the tapered thorn and the pre- protection ring are integral type connection structure.Through the above way; the present invention can improve piston rod of shock absorber for vehicles stabilization, security; it can be installed additional in piston bar body into pre- protection ring; pre- protection ring cushion impact forces can be utilized when piston bar body is subject to greater impact spring-compressed, and tapered thorn can prevent piston bar body from being collided damage.
Description
Technical field
The present invention relates to automobile absorber field, more particularly to a kind of protection type piston rod of shock absorber for vehicles.
Background technology
Damper, concussion when being for suppressing to rebound after spring shock-absorbing and the impact from road surface.It is widely used in automobile,
To accelerate the decay of vehicle frame and body vibrations, to improve ride of vehicle.
When by uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring itself also has back and forth
Movement, and damper is exactly for suppressing this spring jump.Damper is too soft, vehicle body will vertical bounce, damper is too
It is hard to can bring about too big resistance, hinder spring normal work.In the retrofit process on suspension, hard damper will
Mutually arrange in pairs or groups with hard spring, and the hardness of spring and car weight are closely bound up, therefore heavier car generally uses harder damping
Device.The device to connect with drawing shake bent axle, for the torsional shaking for the bent axle that contends with（I.e. bent axle subject cylinder igniting impact force and twist
Phenomenon）.
The content of the invention
The invention mainly solves the technical problem of providing a kind of protection type piston rod of shock absorber for vehicles, it is possible to increase automobile
Shock absorber piston rod is stable, security, can be installed additional into pre- protection ring in piston bar body, be subject to greater impact in piston bar body
Pre- protection ring cushion impact forces can be utilized during spring-compressed, and tapered thorn can prevent piston bar body from being collided damage.
In order to solve the above technical problems, one aspect of the present invention is：A kind of protection type automobile shock-avoiding is provided
Device piston rod, including piston bar body, the piston bar body are equipped with multistage external screw thread, are threaded on the external screw thread
Pre- protection ring, shape is placed on the piston rod outer body face the pre- protection ring in a ring, the pre- protection ring upper and lower end face
Upper protrusion is provided with rubber cushion block, and also protrusion is provided with tapered thorn on the pre- protection ring exterior annular face, and the tapered thorn is raised
Face is cone body, and the tapered thorn and the pre- protection ring are integral type connection structure.
In a preferred embodiment of the present invention, the rubber cushion block is hard plastic, and the rubber cushion block protruding end is arc-shaped
Face.
In a preferred embodiment of the present invention, the rubber cushion block height of projection is 20cm-45cm.
The beneficial effects of the invention are as follows：The present invention can improve piston rod of shock absorber for vehicles stabilization, security, piston rod sheet
It can be installed additional on body into pre- protection ring, pre- protection ring shock absorbing can be utilized when piston bar body is subject to greater impact spring-compressed
Power, and tapered thorn can prevent piston bar body from being collided damage.
