Except or alleviate car and fall the injury causing to occupants；In addition also has section hydraulic oil meeting through regulator hole, pressure ports
Enter epicoele from damping hole, because unidirectional damping block upper end is provided with 45 ° of inclined plane, therefore hydraulic pressure towards pressure ports side
Oil has a downward active force to it, thus overcoming back-moving spring (its design resistance is less) that unidirectional damping block is pressed into chute
Interior, remove the flow resistance that unidirectional damping block is formed to damping in the hole hydraulic oil.
And after collision is to limit, upper buffer spring and lower buffer spring release elastic potential energy drive piston rod up, this
When closed check valve, the hydraulic oil of epicoele can not enter cavity of resorption by oil-through hole, be only capable of above damping in the hole unidirectional damping block
Gap location flow into pressure ports, and from regulator hole enter cavity of resorption so that flow resistance increase, the resilience of the limit buffer device making
Become is slow, it is to avoid the secondary injury that elastic potential energy quick release may be brought to passenger again.
In sum, this new structural design is reasonable, by hydraulic oil in upper buffer spring, lower buffer spring and cylinder body
Triple role is it is achieved that limit buffer in rational time and move distance；Have simultaneously and effectively can slow down in bounce-back anti-
Bullet, it is to avoid the secondary injury that elastic potential energy quick release may be brought to passenger again.
