The invention discloses a multi-mode composite steering chassis and an engineering machinery vehicle. The multi-mode composite steering chassis comprises a front vehicle frame, a rear vehicle frame, aplurality of wheels arranged on the front vehicle frame and the rear vehicle frame respectively, driving devices corresponding to the wheels, wheel steering devices corresponding to the wheels, and avehicle control unit. The multi-mode composite steering chassis has the advantages that high-speed and low-speed driving and various steering modes can be achieved, the universalization degree is high, the modular design is achieved, the design period of new products can be shortened to a certain extent, and the purchasing cost is reduced; a manual mode and an automatic mode are adopted to selecta steering mode so that a smaller turning radius at a low rotating speed and the steering running stability of the vehicle at a high rotating speed can be realized, and the steering capacity and thepassing capacity of the vehicle are improved; and meanwhile, mechanical limiting and sensor signal acquisition are added so that the driving safety is improved.

    本发明公开了一种多模式复合转向底盘及工程机械车,包括:前车架、后车架、分别设在前车架和后车架上的若干车轮、对应于每个车轮的驱动装置、对应于每个车轮的车轮转向装置以及整车控制器。优点:可实现高低速行驶,多种转向模式,通用化程度高,模块化设计,从一定程度可缩短新产品的设计周期,降低采购成本;具备手动模式和自动模式选择转向模式,可实现低转速下更小的转弯半径,高转速下车辆转向行驶的稳定性,提高了车辆的转向能力和通过能力;同时增加了机械限位和传感器信号采集,提高行驶的安全性。
