Frictional force control based frictional damping type shock absorber

Abstract

The invention belongs to the technical field of shock absorbers, and particularly relates to a frictional force control based frictional damping type shock absorber. The frictional force control basedfrictional damping type shock absorber comprises a first fixing ring, a shock absorbing spring, a friction mechanism, a shock absorbing sleeve, a second fixing ring, a connecting rod, a telescoping sleeve, a telescoping rod, a first plate spring, an arc-shaped plate, a frictional plate, a circular hole, limiting grooves, a storing chamber, etc., wherein the storing chamber is formed in the shockabsorbing sleeve; the through circular hole is formed in the upper end surface of the storing chamber, and two limiting grooves are symmetrically formed in the inner circle surface of the storing chamber; two groups of second supporting seats are symmetrically mounted on the lower end surface of the storing chamber and fit the corresponding limiting grooves; and two second supporting seats in eachgroup are linearly distributed in the directions of the limiting grooves. According to the shock absorber, the impact force can be born in case of excessively high speed of the impact force or low speed of the impact force, and the shock absorber remains the impact force absorbing effect, so that unnecessary economic loss can be avoided.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to a friction damping shock absorber based on friction control. Background technique [0002] Existing shock absorber adopts spring and shock absorber to form jointly more at present. The shock absorber is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact. The spring plays the role of easing the impact, changing "one impact with high energy" into "multiple impacts with small energy", and the shock absorber gradually reduces "multiple impacts with small energy". If the shock absorber is broken, the car will bounce after every pothole and ups and downs, and the shock absorber is used to suppress this bounce. Without a shock absorber, the rebound of the spring cannot be controlled, and the car will have serious bounce when it encounters a rough road, and the vib...

Problems solved by technology

[0005] The problem to be solved by the present invention is to provide a frictional damping shock absorber based on frictional force control to overcome the fact that shock absorbers in the prior art mostly use hydraulic rods and springs in combination. When the impact force is too fast, the hydraulic oil will Will not flow out quickly, will cause damage to the hydraulic rod, thus causing unnecessary economic losses
