Background technique

Suspension is the general term for all force-transmitting connection devices between the frame of a car and the axle or wheels. Or the impact force of the car body, and attenuate the vibration caused by it, so as to ensure that the car can run smoothly. A typical automobile suspension includes three parts: elastic elements, shock absorbers and force transmission devices. These three parts play the roles of buffering, vibration reduction and force transmission respectively. The elastic elements actively transmit vertical forces and dampen shocks and vibrations caused by road irregularities. From the point of view of the car, the elastic element refers to the coil spring, which only bears the vertical load, eases and suppresses the impact of the uneven road on the car body, and has the advantages of small space occupation, low mass and no need for lubrication. The shock absorber refers to the hydraulic shock absorber, which is to accelerate the attenuation of the vibration of the vehicle body. The force transmission device is used to transmit longitudinal force, lateral force and moment, and ensure that the wheel has a certain relative motion law relative to the frame or body.

The suspension composed of such shock absorbers, once the vehicle is loaded, the height of the vehicle chassis from the ground is basically fixed. Such automobile suspension cannot satisfy the needs of car owners who need to lower the chassis of the vehicle or drive in the field to raise the chassis when driving in urban areas.

The outer side of the housing 2 is also sleeved with a housing 3 that can slide up and down along the housing 2. The housing 3 has a hydraulic chamber 3 inside. , the above-mentioned piston rod passes through the casing two and enters the hydraulic chamber three of the casing three.

The automobile shock absorber is used as an important part of the automobile suspension. The upper end of the housing one of the automobile shock absorber is connected with the elastic element, and the lower end of the housing three is connected with the force transmission device. When the car is running, the first casing is retracted into the second casing, and the second casing can also be retracted into the third casing, which meets the needs of car owners who need to lower the chassis of the vehicle when driving in urban areas or raise the chassis when driving in the wild .

In the above automobile shock absorber, the first connecting ring is fixed on the shell three, and the second connecting ring is fixed on the first shell. Through the connecting ring one, the shell three is connected with the force transmission device, and through the connecting ring two, the shell one is connected with the elastic element conveniently.

In the above automobile shock absorber, the first casing, the second casing and the third casing are made of stainless steel.

Compared with the prior art, the utility model has the beneficial effects of reasonable design, convenient installation, low cost, and can effectively improve or lower the chassis of the automobile.
