Specific implementation mode
In order to deepen the understanding of the present invention, present invention will be further explained below with reference to the attached drawings and examples, the implementation
Example is only used for explaining the present invention, does not constitute and limits to protection scope of the present invention.
As shown in figures 1 and 3, a kind of rubber vehicle suspension device with variable rigidity property, the draft hitch include
The connecting bracket 1 on top and the bracket 2 of lower part, 1 top of the connecting bracket are fixedly connected with bicycle beam, 2 both ends of the bracket point
It is not connect with bridge seat, bridge seat is fixed in vehicle bridge, and the bottom end of the connecting bracket 1 passes through rubber bullet with the upper end of bracket 2
Spring 3 connects, and 3 outside of the rubber spring is equipped with damper 5, and damper 5 is bolted with bracket 2；The connecting bracket 1
Variable cross-section buffer stopper 4 is additionally provided between bracket 2, the variable cross-section buffer stopper 4 is fixedly mounted on 2 top of bracket, and described become cuts
Gap 7 is equipped in face buffer stopper 4, the gap 7 is lenticular, and column support 71 is equipped between lenticular,
The variable cross-section buffer stopper 4 is thermoplastic polyester material.
In the above-described embodiments, after vehicle installation Rubber mount, when running car is on road surface because of the change on ground
To change and is given a shock and impacts, the strength of these impacts passes to the bicycle beam on top by wheel, before being transmitted to bicycle beam, via
Draft hitch absorbs a part of impact, and variable cross-section buffer stopper 4 between connecting bracket 1 and bicycle beam has the function of buffering,
In lenticulated gap 7 and column support 71 deformation quantity that can absorb impact force to greatest extent, and generate
