Bridge.
Due to torsion bridge type suspension and wheel be all only by suspension before two bushings be connected with vehicle body, if
Using the bushing of statement in background technology, when vehicle is subject to lateral forces, side force toe-in is very big, lateral at bushing
Displacement is also very big, has a strong impact on the stability of vehicle traveling, especially when vehicle takes a sudden turn, easily causes driver's fear, though
So increase the rigidity of bushing, lateral displacement can be reduced, but, just ratio is larger for the vibration of vehicle and noise, the ride comfort of suspension
It is deteriorated.
Using toe-in boundling bushing provided in an embodiment of the present invention, the small end rubber bodies of this prenex boundling bushing and greatly end rubber
Colloid and bushing mounting bracket on vehicle body only 1mm apart, when vehicle is subject to lateral forces, small end rubber bodies and greatly end rubber
Body is contacted with bushing mounting bracket on vehicle body quickly, and meanwhile, in prenex boundling bushing, engraved structure reduces axial rigidity, improves
Promptness and stationarity that small end rubber bodies and big end rubber bodies contact with bushing mounting bracket on vehicle body, before control side force
The increase of bundle, lateral displacement also very little, vehicle handling stability is fine.
Because toe-in boundling bushing provided in an embodiment of the present invention has efficiently controlled the side force of torsion bridge type suspension
Prenex change, can reduce the rigidity of the rubber of bushing, improve vehicle and be subject to road shocks to produce in the process of moving
Vibration and noise, improve the ride comfort of the traveling of vehicle meanwhile.
The engraved structure of prenex boundling bushing further reduces the rigidity of rubber fore-and-aft direction, so that vehicle is braked and starts
When more steady.
Construction, feature and the action effect of the present invention, above institute are described in detail above according to the embodiment shown in schema
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
Want made change, or be revised as the Equivalent embodiments of equivalent variations, when still covered with diagram without departing from description spiritual,
All should be within the scope of the present invention.
