Described piston 3 is set to concave spherical surface on the surface that it is arranged in auxilliary air chamber 8.
The utility model vibration attenuation mechanism is as follows:
When being subjected to resistance in the vehicle driving, the elastic element compression that suspension is used promotes connecting rod and is subjected to displacement to the lower end, and connecting rod drives piston and moves to auxilliary air chamber in cylinder.At this moment, main gas tank's volume increases pressure and diminishes, and auxilliary gas chamber volume reduces pressure and increases, and valve block is opened, the gas flow main gas tank of auxilliary air chamber.When auxilliary air chamber was equal with main gas tank's air pressure, valve block was closed under the effect of valve block spring, and auxilliary air chamber and main gas tank are in the separation state.
After the suffered resistance of vehicle disappeared, under the effect of elastic element, connecting rod drove piston and moves to main gas tank in cylinder.At this moment, auxilliary gas chamber volume increases pressure and diminishes, because two end forces of piston are poor, the power of generation can reduce rebounding force.Main gas tank's volume reduces pressure and increases, and produces resistance, has also reduced rebounding force.
