Abstract

The invention discloses a spring damping shock absorber. The spring damping shock absorber includes an upper seat, a lower seat, damping springs located between the upper seat and the lower seat, anda piston damping device; the piston damping device is arranged in the damping springs; the central axis of the damping springs is in coincidence with the central axis of the piston damping device; thepiston damping device includes a piston rod fixed on the lower surface of the upper seat and a piston barrel fixed on the upper surface of the lower seat; a piston barrel cover is installed on the upper end of the piston barrel; the lower end of the piston rod is provided with a piston head stretching into the piston barrel; and the space located under the piston head in the piston barrel is a cavity. Through the double arrangement of spiral springs and the piston damping device, the problem of small damping of traditional single metal spiral springs can be overcome; and under the dual function of the piston damping device and the damping springs, the damping effect of the spring damping shock absorber can be better, and the spring damping shock absorber is simple in structure and suitable for application with wider scopes.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to a spring damping shock absorber. Background technique [0002] The coil spring has excellent shock absorption performance and is an important part of the shock absorption device. It has the actual dynamic stiffness basically consistent with the calculated static stiffness, the lowest natural frequency is as low as 1Hz or even lower, the load capacity is large enough, and the production quality of the spring is And specifications are relatively easy to control and other advantages, but the damping of the coil spring is too small. Therefore, when it is used as a vibration isolation element, other methods must be used to increase the damping value of the shock absorber. Most of the damping devices in the prior art realize the damping function through the combination of multiple groups of coil springs, but the effect is often not ideal. Contents of the invention [0003] ...
