Example Embodiment

[0013] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0014] Such as figure 1 with figure 2 As shown, a shock absorber includes a cylinder 1, a piston rod 2, a piston 3, an oil guide hole 4, an end cover 5, and a bottom plate 6. The piston rod 2 and the piston 3 are located in the cylinder 1, and the guide There are three oil holes 4, which are respectively located on the two end sides and the middle side of the cylinder block 1. The end cover 5 and the bottom plate 6 are respectively connected to the two ends of the cylinder block 1, and the upper end of the cylinder block 1 is provided with a guide sealing device 7. The guide sealing device 7 includes a guide sleeve 8 and an oil seal ring 9. The cylinder block 1 is divided into an inner cylinder 10 and an outer cylinder 11. A buffer cavity 12 is formed b...

Abstract

The invention discloses a damper and relates to the technical field of automobile parts. The damper comprises a cylinder, a piston rod, a piston, three oil guide holes, an end cap and a baseplate, the piston rod and the piston are positioned in the cylinder, the oil guide holes are positioned in the side faces at two ends and in the side face in the middle respectively, the end cap and the baseplate are connected with two ends of the cylinder respectively, a guide sealing device is arranged at the upper end of the cylinder and comprises a guide sleeve and an oil seal ring, the cylinder is divided into an inner cylinder and an outer cylinder, a buffering cavity is formed between the inner cylinder and the outer cylinder, thickness of the buffering cavity is 8-10mm, a one-way overflow valve is arranged at each of two ends of the inner cylinder, springs are arranged at two ends of the piston, a boss is arranged at the lower end of the piston, and a groove is formed in the upper surface of the baseplate. By the damper, response speed of oil can be increased, stable changing of unloading hydraulic pressure can be ensured, and oscillation of the piston can be slowed down; the springs can avoid direct colliding between the piston and two ends of the cylinder. The damper is simple in structure and high in safety.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a shock absorber. Background technique [0002] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. The shock absorber is a vulnerable part during the use of the car. The performance of the shock absorber will directly affect the stability of the car and other factors. The life of the parts. For example, the application number 201010527123.2 discloses a shock absorber, which includes a cylinder, an oil seal, a piston rod, a piston, a bottom plate and a spring. The body is fixedly connected, and the bottom plate is provided with a spring. This invention has a simple structure and good sealing performance. Because the spring is installed on the bottom plate, and the piston is made of rubber material, the shock absorption effect is greatly increased, and it also has the performance of bu...
