The construction of automobile shock absorber
2023-03-17
The suspension system of a car is one of the most important components that ensure a smooth and safe ride. One of the key elements of the suspension system is the Shock Absorber, also known as the damper or the strut. The shock absorber is designed to absorb the shocks and vibrations that are generated by the car's motion, and to keep the wheels in contact with the road surface.
The basic structure of a shock absorber consists of a cylinder filled with hydraulic fluid, a Piston that moves up and down inside the cylinder, and a piston rod that connects the piston to the car's suspension. The cylinder is mounted to the car's frame, while the piston rod is connected to the wheel hub. When the wheel hits a bump, the piston moves up and down inside the cylinder, compressing the hydraulic fluid and creating resistance against the motion of the wheel.
There are two types of shock absorbers: the twin-tube and the monotube. The twin-tube shock absorber has two cylinders, an inner and an outer one, separated by a piston. The inner cylinder contains the piston and the hydraulic fluid, while the outer cylinder acts as a reservoir for the fluid. The monotube shock absorber, on the other hand, has a single cylinder that contains both the piston and the hydraulic fluid.
The piston inside the shock absorber is designed to regulate the flow of hydraulic fluid through small holes or orifices. As the piston moves up and down, the fluid is forced through these orifices, creating resistance against the motion of the wheel. The amount of resistance generated by the shock absorber depends on the size of the orifices, the viscosity of the fluid, and the speed at which the piston moves.
In addition to the hydraulic fluid, shock absorbers also contain a number of other components that help to dampen the vibrations and reduce noise. These include rubber bushings, which help to absorb the shock and reduce friction between the piston and the cylinder, and a dust cover, which protects the piston rod from dirt and debris.
In conclusion, the shock absorber is a critical component of a car's suspension system. Its main purpose is to absorb the shocks and vibrations generated by the car's motion, and to keep the wheels in contact with the road surface. The structure of a shock absorber consists of a cylinder filled with hydraulic fluid, a piston that moves up and down inside the cylinder, and a piston rod that connects the piston to the car's suspension. There are two types of shock absorbers: the twin-tube and the monotube.

Finally, shock absorbers also contain a number of other components that help to dampen the vibrations and reduce noise.
