Problems solved by technology

[0003] Trucks often need to transport materials such as gravel and coal mines, so they often experience rough road conditions such as mountain roads, mud roads, and gravel roads. However, the existing shock absorbers used in suspensions basically have a fixed damping value. , can not be adjusted, when in use, it is impossible to buffer the impact brought by different road conditions, and it is impossible to make the truck run more smoothly

Embodiment 1

[0032] refer to Figure 1-9 , is the first embodiment of the present invention, which provides a hydraulic shock absorber for truck suspension. The hydraulic shock absorber for truck suspension includes a hydraulic shock absorber 100 and a damping adjustment member 200. The damping adjustment member 200 It is used to change the circulation path of the liquid in the hydraulic shock absorber 100, and the damping of the hydraulic shock absorber is changed through the size of the diameter of the flow path, so that the truck can adapt to different road conditions.

[0033] Specifically, the hydraulic shock absorber 100 includes a damper cavity 101, a piston 102, a connecting rod 104, a baffle 106 and a spring 107, the connecting rod 104 connects the piston 102 and the baffle 106, and the piston 102 is arranged in the damper cavity 101 , Two first ring grooves 101a are arranged on the side of the damper cavity 101 .

[0034] The damping adjustment member 200 includes a first adjust...

Abstract

The invention discloses a hydraulic damping device for a truck suspension. The hydraulic damping device comprises a hydraulic damping piece and a damping adjusting piece, wherein the hydraulic damping piece comprises a damper cavity, a piston, a connecting rod, a baffle and a spring, and the damping adjusting piece comprises a first adjusting ring, a second adjusting ring, a driving piece and a shell. According to the device, the first adjusting ring and the second adjusting ring are synchronously adjusted through the driving piece, and therefore, a flowing path of liquid in the damper cavity can be changed; and the damping of the hydraulic damping piece is changed according to the diameters of different flowing paths, therefore the proper damping can be selected by a truck according to road conditions, and the truck is smoother in the running process.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to a hydraulic shock absorbing device for truck suspension. Background technique [0002] Truck suspension is a general term for all force-transmitting connection devices between the frame and or wheels of a truck. The impact force of the car body and reduce the vibration caused by it to ensure that the car can run smoothly. In order to accelerate the attenuation of the vibration of the frame and the body, shock absorbers are widely used on the suspension to suppress the shock and shock when the spring rebounds after absorbing the shock. Impact from the road. [0003] Trucks often need to transport materials such as gravel and coal mines, so they often experience rough road conditions such as mountain roads, mud roads, and gravel roads. However, the existing shock absorbers used in suspensions basically have a fixed damping value. , can not be adjusted, when in use...
