Abstract
The invention discloses a shock absorber and relates to the technical field of automobile parts. The shock absorber comprises a cylinder block, a piston rod, a piston, oil guide holes, an end cover and a bottom plate. The piston rod and the piston are located in the cylinder block. The number of the oil guide holes is three. The oil guide holes are located in the side faces of the two ends and the middle side face of the cylinder block respectively. The end cover and the bottom plate are connected with the two ends of the cylinder block respectively. The upper end of the cylinder block is provided with a guiding and sealing device. The guiding and sealing device comprises a guide sleeve and an oil seal ring. The cylinder block is divided into an inner cylinder and an outer cylinder. A buffer cavity is formed between the inner cylinder and the outer cylinder. The thickness of the buffer cavity ranges from 8 mm to 10 mm. The two ends of the inner cylinder are respectively provided with a one-way overflow valve. The two ends of the piston are provided with springs. The lower end of the piston is provided with a boss. The upper surface of the bottom plate is provided with a groove. The shock absorber can increase the response speed of oil, ensure the steady change of the unloading hydraulic pressure and slow down shock of the piston, and the springs can prevent direct collision between the piston and the two ends of the cylinder block, so the shock absorber is simple in structure and good in safety performance.
