Automobile air shock absorber
Shanghai Songjiang shock absorber Group Co., Ltd.: automotive air shock absorber “good elasticity, high plasticity” information, Songjiang group for many customers to provide higher quality products, continue to develop new products, constantly walk in the forefront of the industry, another new product “automotive air” shock absorber was born, all using automatic production line production, welcome to our factory field investigation, the following is the details Introduction.
Automotive air shock absorbers are called buffers, which control unnecessary spring movement through a process called damping. The shock absorber can slow down and weaken the vibration motion by converting the kinetic energy of suspension into heat energy dissipated by hydraulic oil. To understand how it works, it’s best to look at the internal structure and function of the shock absorber.
The shock absorber is basically an oil pump mounted between the frame and the wheel. The upper support of the shock absorber is connected to the frame (i.e. sprung mass), and the lower support is connected to the axle near the wheel (i.e. unsprung mass). In the double cylinder design, one of the most common types of shock absorber is the upper bracket connected to the piston rod, which is connected to the piston, and the piston rod is located in a cylinder filled with hydraulic oil. The inner cylinder is called the pressure cylinder, and the outer cylinder is called the oil reservoir. The reservoir stores excess hydraulic oil.
When the wheel meets the bumpy road surface and makes the spring compress and stretch, the energy of the spring is transmitted to the shock absorber through the upper support and downward to the piston through the piston rod. There are holes in the piston. When the piston moves up and down in the pressure cylinder, hydraulic oil will leak out of these holes. Because these holes are very small, only a small amount of hydraulic oil can pass under great pressure. This reduces the speed of the piston and slows down the movement of the spring.
The working cycle of the shock absorber consists of two working cycles. Compression cycle refers to the hydraulic oil under the piston when the piston moves downward, and the hydraulic oil above the piston when it moves upward to the top of the pressure cylinder. For a typical automobile or light truck, the resistance in the tensile cycle is greater than that in the compression cycle. In addition, it should be noted that the compression cycle controls the movement of the unsprung mass of the vehicle, while the tensile cycle controls the movement of the heavier sprung mass.
