The first spring 24 of lower compression and second spring 211, the first spring 24 and second spring 211 play preliminary shock absorbing effect；It
Second spring 211 exerts a force to the arch bridge portion of preset plate 21 afterwards, and now preset plate 21 and bipeltate 6 play further slow
Damping effect is rushed, finally because the preset arch bridge shape portion of plate 21 declines so that the connecting rod 22 for being articulated with preset plate 21 is pressed
Contracting shock absorber 23, now shock absorber 23 play further buffering and damping effect, in vehicle by rear, each part is replied successively
To origin-location, subsequent vehicle is not influenceed and is passed through.
Reference picture 4, opened up in the bottom surface of housing 4 it is some run through fixture 5, and communication with cavity body 41 and outer chamber 42 go out
Water hole 8, the setting of apopore 8 can avoid, at rainwater day, having water to be gathered in housing 4, influenceing use of the present utility model
Effect.
