A kind of resistance adjustable shock absorber for automobile

Abstract

The invention discloses a resistance-adjustable shock absorber for automobiles, relates to the technical field of shock absorbers, in particular to a resistance-adjustable shock absorber for automobiles, including a resistance-adjustable shock absorber sleeve body, the resistance of which can be adjusted The inner cavity of the adjustable shock absorber sleeve body is movably fitted with a hollow sleeve rod, and the top of the hollow sleeve rod is fixedly connected with a support plate. The resistance-adjustable shock absorber for automobiles is used through the cooperation of movable plates, auxiliary shock-absorbing springs and support plates. Auxiliary shock absorption not only avoids the problem of damage to the adjustable resistance shock absorber for automobiles in the case of huge vibrations, but also improves the shock absorption effect of the adjustable resistance shock absorber for automobiles. The auxiliary plunger rod The main body is reset, which improves the working quality of the resistance-adjustable shock absorber for automobiles.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a shock absorber with adjustable resistance for automobiles. Background technique [0002] The resistance-adjustable shock absorber cylinder is equipped with a piston, and a hollow connecting rod is installed in the middle hole of the piston. The upper end of the hollow connecting rod is fixed on the lower shell of the air chamber, and a plunger rod and a plunger are also installed in the hollow connecting rod. The upper end of the plunger rod leans against the spring seat and the diaphragm. A spring is installed between the spring seat and the plunger rod. The lower end of the hollow connecting rod is provided with an orifice close to the upper surface of the piston, and the resistance can be adjusted. The shock absorber is used on the suspension whose elastic element is an air spring. When working, as the load of the vehicle increases, the air pressure in the air spri...

AI Technical Summary

Problems solved by technology

When the position of the plunger relative to the orifice on the hollow connecting rod reaches the beginning of plugging, the channel cross-sectional area of ​​the orifice begins to decrease, so the amount of liquid passing through the orifice decreases, which increases the flow resistance of the oil. When the load decreases, the plunger moves upwards, and the channel interception area of ​​the orifice increases, which reduces the flow resistance of the oil. However, after the resistance adjustable shock absorber is used for a long time, the temperature of the oil and the cylinder due to friction will increase. Under the effect of high temperature, the oil will cause high temperature impact on other structures inside the cylinder, and at the same time affect the effect of shock absorption. At the same time, after long-term use, due to friction, the reset of the adjustable resistance shock absorber will often be unsmooth. , the phenomenon of half-resetting or jamming will seriously affect the performance of the car, so we propose a resistance-adjustable shock absorber for cars
