The invention discloses a passenger vehicle emergency braking multifunctional auxiliary wheel mechanism which comprises telescopic columns, crank-shaped wheel legs, a wheel shaft, an auxiliary small wheel and a brake mechanism; the telescopic columns are arranged on the two sides of a vehicle in pairs taking the central axis of the vehicle as the symmetry axis and located between front and rear wheels of the vehicle; the telescopic columns are rigidly connected to the bottom surface of the vehicle; the crank-shaped wheel legs are arranged at the telescopic ends of the telescopic columns in a sleeving manner; the crank-shaped wheel legs are rotationally connected with the telescopic ends of the telescopic columns; the wheel shaft is fixedly connected with the crank-shaped wheel leg, the auxiliary small wheel is rotatably connected with the wheel shaft, the rotating axis of the crank-shaped wheel legs is in the vertical direction, the rotating axis of the auxiliary small wheel is in thehorizontal direction, the braking mechanism is used for braking the auxiliary small wheel, and the rotating angle of the crank-shaped wheel leg is smaller than the maximum steering angle of the frontwheels of the vehicle. The invention further discloses a control method of the passenger vehicle emergency braking multifunctional auxiliary wheel mechanism, braking friction can be increased or support can be provided, and braking side slipping and vehicle overturning are reduced.
本发明公开了乘用车应急制动多功能辅助轮机构,包括伸缩柱、拐形轮腿、轮轴、辅助小轮和制动机构,伸缩柱以车辆中轴线为对称轴成对设置于车辆的两侧且位于车辆的前后轮之间,伸缩柱刚性连接于车辆的底面,拐形轮腿套设于所述伸缩柱的伸缩端,拐形轮腿与伸缩柱的伸缩端转动连接,轮轴与拐形轮腿固定连接,辅助小轮与轮轴转动连接,拐形轮腿的转动轴线为竖直方向,辅助小轮的转动轴线为水平方向,制动机构用于制动辅助小轮,拐形轮腿的转动角度小于车辆的前轮最大转向角度。本发明还公开了乘用车应急制动多功能辅助轮机构的控制方法,本发明可增加制动摩擦或者提供支撑,减小制动侧滑、车辆倾覆的发生。
