Description
Technical field
The utility model is related to rear wheel supporting structure, more particularly to a kind of rear wheel for multi link formula independent suspension
Supporting structure.
Background technology
Multi-link suspension refers to be made up of three or more than three cylinder lever connecting rods, and can provide the control of multiple directions
Power, makes tire have the suspension frame structure of relatively reliable driving trace.But at present, because three bar linkage structures can not meet people
For chassis handling higher pursuit, only structure is more accurate, the more accurate four link type of positioning and five connecting rods
Formula suspension can just deserve to be called real multi link formula, and both suspension frame structures are usually applied separately to front wheels and rear wheels.
The operation principle of multi-link lever suspension fork is the coefficient combined effect of connecting rod.When vehicle is turned, rear wheel
Direction of displacement is played pendulum just with steering front wheel on the contrary, can make vehicle body loss of stability if displacement is excessive.Now, it is preceding
The effect of rearmounted registration arm begins to show, and they mainly enter row constraint to the toe-in angle of trailing wheel, make it in controlled range；Phase
Instead, because the toe-in angle of trailing wheel is constrained in controlled range, the lateral stability of vehicle can be made if trailing wheel camber angle is excessive
Property lower, be on the one hand preferably to make car so adding the control arm to entering row constraint above and below wheel in multi-link lever suspension fork
Wheel positioning, on the other hand then makes the reliability and rigidity of suspension further improve.
Independent suspension has advantages below：
1）, can guarantee that more accurate positional parameter, and suspension positional parameter is adjustable；
2）, load change than it is larger when both sides wheels be independent of each other each other；
3）, than the design freedom of larger kinematics and elastokinematics；
4）, road surface vibration and noise can be easily separated；
Independent suspension also has as a drawback that：
1）, performance is not good when cross-country；
2）, it is complicated, cost is high, and space-consuming is big；
3）, rigidity be not so good as SA；
The existing advantage of independent suspension also has shortcoming, but advantage is more than shortcoming as a whole, so independent on passenger car
The equipment constant of suspension rises.And as the wheel stand of one of important component in independent suspension must be fulfilled for it is following some
It is required that：
1）, trouble-freely can bear and transmit wheel institute is strong and torque；
2）, can be between motor point and wheel bearing structure space play transitional function；
3）, must can support wheel bearing, caliper and elastic support；
In addition, wheel stand can also support sensor and thermal insulation board, the guiding of oil pipe and linear speed can be also integrated with thereon
Groove etc..
There is problems with verification process is made in existing trailing wheel hub holder：
1）, it is complicated, increase casting difficulty；
2）, complicated structure easily cause stress concentration in Ge Bian intersections；
3）, discontinuity；
4）, be fitted without the elongated hole of eccentric bolt in hub bracket, camber angle can only be by the bias at that end of support
Bolt is adjusted, and yielding after support stand under load, is unfavorable for the control of camber angle.
The content of the invention
In order to solve the problems of the prior art, the utility model provides a kind of be used for after multi link formula independent suspension
Wheel stand structure, with lightweight structure, it is possible to improve structure stress distribution uneven.
The utility model provides a kind of rear wheel supporting structure for multi link formula independent suspension, including support master
Body, the rack body is provided with strip hole, eccentric bolt of the strip hole provided with regulation camber angle.
As further improvement of the utility model, the rack body is provided with boss, and the surface of the boss is wheel
Hub holder mounting surface, the face on the basis of the hub bracket mounting surface, the height of the boss is H1, then 5mm≤H1≤15mm；
The face contacted with brake caliper to reference plane distance is H2, then 22mm≤H2≤25mm；The threaded bolt contacts face of brake caliper installation place
It is H away from reference plane distance3, then 40mm≤H3≤48mm。
As further improvement of the utility model, the rack body is provided with reference circle and is centered around the reference circle
