Abstract

A damper for earthquake resistance of building, car,v ehicles, and landing chassis features that the compressable nature and energy-accumulating action of gas and the damp action of fluid are used to suck vibration energy and the expansion of gas is used to reset the plunger of damper.

Description

Liquid-gas damper
The present invention is a kind of vibration damping equipment, can be used for the antiseismic of building, the damper of automobile, motorcycle, tractor, tank etc., anti-vibrations such as the undercarriage of aircraft, percussion mechanism.
Working principle of the present invention is as follows:
When being subjected to impacting, gas 14 is compressed in the plunger 12, and hydraulic oil 15 rises by the damping hole of vibration damping valve block 6, thereby utilizes the energy storage effect of gas and the damping function of liquid to play the vibration reduction and cushioning effect.After the impact, gas 14 expands, and the vibration damping valve block falls, and it is big that liquid chunnel becomes, the periphery of hydraulic oil by the vibration damping valve block and the very fast decline in gap of 12 in gas storage piston, and the gas storage plunger resets rapidly.
Pressurized gas 14 can be controlled at certain pressure, volume in advance according to the requirement of different bearer ability and vibration damping amplitude.
Compare with existing liquid spring unit on the automobile, the present invention has energy storage, vibration damping, supporting role concurrently.And the latter can only vibration damping.Therefore:
1, the present invention can reduce the carrying of automobile leaf spring;
2, leaf spring can not be in always and be subjected to heavy condition;
3, can not make during overload impact car body that hard collision takes place.
The present invention is drawings attached in addition, among the figure:
1, one-way valve; 2, spring; 3, hollow stud; 4, cylinder bottom head; 5, seal washer; 6, vibration damping valve block; 7, vibration damping valve block carriage; 8, carriage screw; 9, seal ring; 10, vibration damper cylinder; 11; Screw; 12, gas storage plunger; 13, cylinder cover; 14, pressurized gas; 15, hydraulic oil; 16, seal washer.

Claims (4)

1, the present invention is a kind of vibration damping equipment, it is characterized in that utilizing the energy storage effect of gas, and the damping function of liquid reaches the purpose of vibration damping.
2, vibration damper according to claim 1 is characterized in that it by one-way valve, vibration damping valve block 6, vibration damping valve block carriage 7, vibration damper cylinder 10, gas storage plunger 12, pressurized gas 14, hydraulic oil 15 compositions such as grade.
3, according to claim 1,2 described vibration dampers, it is characterized in that pressurized gas 14 had both played damping effect therein, play a part to make gas storage plunger 12 to reset again, it can be by any compressible gas composition.
4, according to claim 1,2 described vibration dampers, it is characterized in that hydraulic oil 15 plays damping, absorbing therein, it can be made up of any flowable liquid.
