Description
Technical field
The utility model relates to large load manned vehicle rear-suspension system, is specifically related to a kind of manned vehicle rear suspension A arm.
Background technology
Current high-grade manned vehicle rear suspension mostly is multi-connecting-rod separated suspension, and multi-connecting-rod separated suspension has good handling and traveling comfort due to the increase of its controllable parameter, therefore apply widely.But traditional multi-connecting-rod separated suspension also has obvious weakness: first due to the layout between hard spot constraint and each rod member and motion space restriction, the size of rod member size and rubber bush is not easy to strengthen, and therefore traditional multi link rear suspension is difficult to the manned vehicle of large load; Next is lining is not very desirable to the decoupling effect of lock torque, because each leverage is independent of each other, so all rod members all can participate in the effect of resisting lock torque, all linings all can be subject to lock torque when braking, this can affect the performance of lining in suspension property.
Summary of the invention
The purpose of this utility model is to provide a kind of manned vehicle rear suspension A arm, can optimize the decoupling effect of rubber bush, improves the load-carrying capacity of connecting rod.
The utility model is achieved through the following technical solutions:
A kind of manned vehicle rear suspension A arm, rear suspension comprises upper suspension arm, prenex adjustment arm, subframe, coil spring band vibration damper complement, and upper suspension arm one end to be saved with rear steering by bolt and is connected, and the other end is connected with subframe by bolt; Prenex adjustment arm one end to be saved with rear steering by bulb and is connected, and the other end is connected with subframe by bolt; Coil spring band vibration damper complement lower end is connected with upper suspension arm by bolt, coil spring band vibration damper complement upper end is fixedly connected with vehicle body, subframe is fixedly connected with vehicle body, it is characterized in that, manned vehicle rear suspension A arm is hollow and thin-walled foundry goods, it comprises A arm body, four fixing ears are provided with on the left of A arm main body, four fixing ears to be saved with vehicle rear steering by spherical pin and pilot bar and are connected, two curved booms are extended with on the right side of A arm main body, two curved boom ends are equipped with lining, and two curved booms are all fixedly connected with subframe by bolt.
Technical scheme principal feature is: two of traditional multi-connecting-rod separated suspension lower beams are synthesized an independently Control arm---A arm, change two of traditional multi-connecting-rod separated suspension upper booms into a upper suspension arm, retain the toe-in adjustment arm of traditional multi-connecting-rod separated suspension simultaneously; A arm is connected with steering swivel with pilot bar by spherical pin.

Specific implementation
Below in conjunction with accompanying drawing, the utility model is further described:
Consult Fig. 1, a kind of manned vehicle rear suspension, comprise A arm 1, upper suspension arm 2, pilot bar 3, prenex adjustment arm 4, subframe 5, coil spring band vibration damper complement 6, spherical pin 7, A arm passes on left spherical pin 7 and is connected with rear vehicle steering swivel 8 with pilot bar 3, is bolted on below subframe 5 on the right side of A arm; Upper suspension arm 2 one end is saved 8 by bolt and rear steering and is connected, and the other end is connected with subframe 5 by bolt; Prenex adjustment arm 4 one end is saved 8 by bulb and rear steering and is connected, and the other end is connected with subframe 5 by bolt; Coil spring band vibration damper complement 6 lower end is connected with upper suspension arm 2 by bolt, and coil spring band vibration damper complement 6 upper end is fixedly connected with vehicle body, and subframe 5 is fixedly connected with vehicle body.
Consult Fig. 2, manned vehicle rear suspension A arm 1 is the hollow and thin-walled foundry goods of shape approximation A type, and it comprises A arm body 101, A arm main body 101 front end and is provided with four fixing ears, and four fixing ears 102 save 8 by spherical pin 7 with pilot bar 3 and vehicle rear steering and are connected; A arm main body 101 end is extended with rear curved boom 103 and front curved boom 104 respectively to both sides, front and back, and rear curved boom end is provided with back bush 105, and front curved boom end is provided with front lining 106, and two curved booms are all fixedly connected with subframe 5 by bolt.
The manned vehicle rear suspension that the utility model provides decreases rod-type structure, and due to the simplification of upper suspension arm and the integration of Lower control arm, the distance between Control arm considerably increases, and this is that enough spaces have been expanded in the exploitation of Control arm and lining.
A arm is the core component of the manned vehicle rear suspension that the utility model provides, and A arm 1 is designed to overall hollow and thin-walled foundry goods, and as the box like structure closed, A arm 1 has very high intensity while reduction weight.The lock torque of rear suspension is born primarily of A arm 1, the lock torque transmitted by ground is delivered to subframe 5 by spherical pin 7 and pilot bar 3 through A arm body 101 and A arm front and rear bushings 106,105, so just farthest decreases the impact of lock torque on upper suspension arm 2; Simultaneously by the radial rigidity of adjustment A arm lining 106,105 vertical direction and the radial rigidity of pilot bar 3, the individual features to lock torque can also be improved.In addition, the radial rigidity of A arm front lining 106 horizontal direction affects the transient state response of side force, the radial rigidity of A arm back bush 105 horizontal direction affects the longitudinal direction yielding of suspension, corresponding and longitudinally make a concession characteristic by adjusting side force transient state that these two rigidity can improve rear suspension, the arranged direction of A arm front and rear bushings also ensure that the realization of this performance (arrange before and after A arm front lining 106, back bush 105 be with angle).From description above, the performance that the rigidity major effect of A arm lining different directions is different, therefore A arm lining can not produce a very large impact other performance while bearing lock torque, and the performance of lining all directions rigidity clearly, therefore the decoupling effect of A arm lining is very good; Simultaneously due to the existence of A arm structure, also assures that upper suspension arm 2 affects by lock torque very little.The clear superiority that the multi link rear suspension therefore with A arm compares traditional multi-connecting-rod separated suspension is exactly that deceleration and stopping performance is very good.
