The invention discloses a reconfigurable double-wishbone type independent suspension device, which belongs to the technical field of vehicles, and comprises a main shaft, an upper support, a spring damping element, an upper wishbone, a steering knuckle, a lower wishbone, a steering pull rod, a steering actuator and wheels, the upper support is fixedly connected to the main shaft; the upper cross arm and the lower cross arm are hinged with the main shaft; the steering knuckle is hinged between the upper cross arm and the lower cross arm; one end of the spring damping element is hinged to the upper support, and the other end is hinged to the middle of the lower cross arm; two supporting rods are arranged on the steering knuckle, one end of the steering pull rod is hinged to one supporting rod of the steering knuckle, and the other end of the steering pull rod is hinged to the steering actuator. The other supporting rod of the steering knuckle is coaxially connected with a hub of the wheel through a hub rotating pair; the independent suspension device can normally support a vehicle body, meanwhile, the wheel distance and the axle distance can be changed under the driving of the main shaft, the trafficability requirements of the vehicle under different working conditions can be met, and therefore the maneuvering performance of the vehicle is effectively improved.
本发明公开了一种可重构双横臂式独立悬架装置,属于车辆技术领域,该独立悬架装置包括:主轴、上支座、弹簧阻尼元件、上横臂、转向节、下横臂、转向拉杆、转向作动器及车轮;上支座固连在主轴上;上横臂和下横臂均与主轴铰接;转向节铰接在上横臂和下横臂之间;弹簧阻尼元件的一端与上支座铰接,另一端与下横臂的中部铰接;转向节上设有两个支杆,转向拉杆的一端与转向节的一个支杆铰接,转向拉杆的另一端与转向作动器铰接;转向节的另一个支杆通过轮毂转动副与车轮的轮毂同轴连接;该独立悬架装置能够正常支承车体,同时还能够在主轴的带动下实现轮距和轴距的变化,能够适应车辆不同工况下的通过性需求,从而有效提升车辆的机动性能。
