Speed-regulating, pressure-regulating and shock-absorbing supporting device capable of replacing automobile shock absorber steel plate spring

Abstract

The invention relates to the technical field of automobile accessories, in particular to a speed-regulating pressure-regulating shock-absorbing supporting device capable of replacing a steel plate spring of an automobile shock absorber, which comprises a cylinder barrel, a cylinder cap is fixed on the outer wall of the top end of the cylinder barrel, the bottom end of the cylinder barrel is connected with a lower connecting plate, and a buffering shock-absorbing assembly is arranged on the cylinder barrel. The buffering and damping assembly comprises a piston rod and a flow adjusting component, the outer wall of the piston rod is slidably connected with the upper portion of the inner wall of the cylinder barrel, the portion, located below the piston rod, of the inner wall of the cylinder barrel is filled with hydraulic oil, and the portion, located above the hydraulic oil, of the inner wall of the piston rod is filled with nitrogen. And in cooperation with the cylinder barrel, the small piston, hydraulic oil and the flow regulating valve, the pressure borne by a vehicle body can be effectively reduced, meanwhile, the weight of the device is reduced, and buffering softness is achieved during damping.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a speed-regulating and pressure-regulating shock-absorbing supporter that replaces a leaf spring of an automobile shock absorber. Background technique [0002] The common problem of large trucks is that the body is heavier, and it is not very comfortable, because there is often a spring steel plate between the tire and the frame. The spring steel plate is solid and relatively long, so the spring steel plate greatly increases the weight of the car, and the more the wheels, the more springs The more steel plates, the greater the weight of the car, and the elasticity and hardness of the spring steel plate are too large, there is no automatic adjustment function, it is not comfortable enough, and the shock absorption function cannot be completed very softly. Now some cars use air springs instead of spring steel plates, but air The weight of the spring is also relatively heavy. The...

Problems solved by technology

[0004] For this reason, the present invention provides a speed-regulating and pressure-regulating shock-absorbing supporter that replaces the steel plate spring of the automobile shock absorber to solve the problem that some vehicles use air springs instead of spring steel plates, but the weight of the air spring is relatively heavy, and the air spring relies on The folding of the leather bag, folding back and forth has a limited service life, and the manufacturing costs of spring steel plates and air springs are relatively high.
