Embodiment 1

[0029] Such as figure 1 As shown, the double-head shock absorbing device includes an outer cylinder 1, a compression column 2, a damping plate 3, a floating piston 4 and a spring 5; Symmetrically arranged in the outer cylinder 1, two floating pistons 4 are arranged oppositely between the two damping plates 3, and the two floating pistons 4 are connected by a spring 5; two compression columns 2 are respectively inserted through the two ends of the outer cylinder 1 Inside the outer cylinder 1 ; damping holes 6 are opened on the damping plate 3 . A one-way valve 10 leading to the end of the outer cylinder 1 is arranged on the damping plate 3 .

[0030] It works as follows:

[0031] Inside the outer cylinder 1, the space between the end of the compression column 2 and the damping plate 3 is filled with oil. When an external force is applied, the compression columns 2 at both ends move toward the center of the outer cylinder 1 at the same time, compressing the oil to make the oi...

Embodiment 2

[0035] Such as figure 1 As shown, this embodiment is based on Embodiment 1, and a sealing support body 7 is arranged between the outer cylinder body 1 and the compression column 2 .

[0036] A sealing support member 7 is provided to avoid oil leakage in the outer cylinder.

Embodiment 3

[0038] Such as figure 1 As shown, this embodiment is based on Embodiment 2, and the outer circular surface of one end of the compression column 2 inside the outer cylinder body 1 is provided with a retaining ring 8 .

[0039] A retaining ring 8 is provided to prevent the compression column 2 from detaching from the outer cylinder 1

Abstract

The invention discloses a double-head impact absorption device which comprises an outer cylinder, compression pillars, damping plates, floating pistons and a spring. The outer cylinder is horizontally arranged, and the two ends of the outer cylinder are opened. The two damping plates are symmetrically arranged in the outer cylinder. The two floating pistons are oppositely arranged between the two damping plates. The two floating pistons are connected through the spring. The two compression pillars are inserted in the outer cylinder through the two ends of the outer cylinder correspondingly. Damping holes are formed in the damping plates, and the damping plates are provided with one-way valves communicating with the end portion of the outer cylinder 1. When the double-head impact absorption device works, equalization of energy absorption at the two ends and equalization of returning at the two ends are achieved, and the work process can be more stable and more reliable.

Description

technical field [0001] The invention relates to a shock energy absorbing device. Background technique [0002] Shock absorbers are mainly used to absorb shocks from the road. When passing through uneven roads, filter the vibration of the road surface. Shock absorbers are widely used in automobile suspension systems, rail vehicle suspension systems and aircraft landing gear systems. The main function of the shock absorber is to filter the vibration of the road surface, but its more important role is to improve the comfort of passengers, reduce the impact on the chassis of the car, the frame of the rail vehicle and the fuselage of the aircraft, and the impact on the automobile, rail vehicle and aircraft. security plays an extremely critical role. [0003] The existing shock absorber adopts an oil-air hybrid structure, which uses the damping energy generated when the oil passes through the damping hole, and then uses the compression of the gas to further absorb energy. The ...
