Problems solved by technology

Since the car only relies on the shock absorber spring for cushioning, when the car body is suddenly subjected to severe vibration, the shock absorber compresses the spring excessively, and the connecting rod of the shock absorber is likely to collide with the lower support, which greatly affects its use life, and even lead to shock absorption failure

Abstract

The invention discloses a shock absorber which comprises an upper support, a lower support, a buffer spring, a piston cylinder, a piston rod and a buffer device. The buffer device comprises a first buffer piece, a second buffer piece and a third buffer piece; the second buffering piece is arranged in the first buffering piece and movably connected with the first buffering piece, and the third buffering piece is arranged in the second buffering piece and movably connected with the second buffering piece; a first elastic piece is arranged on the side, facing the lower support, of the second buffering piece, the first elastic piece abuts against the lower support, and the second buffering piece is lifted by a preset height relative to the first buffering piece in the natural state through the first elastic piece; a second elastic piece is arranged in the third buffering piece, the second elastic piece lifts the third buffering piece by a preset height in the second buffering piece in a natural state, and the third buffering piece does not protrude out of the second buffering piece. By means of the mode, when the spring of the shock absorber is excessively compressed, multi-stage buffering is formed, and the shock absorber is prevented from being damaged.

Description

technical field [0001] The present application relates to the technical field of automobile manufacturing, in particular to a shock absorber and an automobile. Background technique [0002] As an important device to improve the ride comfort of motor vehicles, increase driving stability and ride comfort, shock absorbers are widely used in different types of motor vehicles such as automobiles and motorcycles. [0003] The current shock absorber generally includes a cylinder installed on the vehicle body, the cylinder contains highly viscous damping oil and is provided with a piston, one end of the cylinder is pierced with a connecting rod, and one end of the connecting rod It is fixedly connected to the wheel frame of the wheel, and the other end is fixedly connected to the piston in the pressure cylinder, and the outside of the connecting rod is sheathed with a spring. When braking, the vehicle body can drive the piston through the connecting rod to compress the damping oil ...
