The invention belongs to the technical field of vehicle chassis, and particularly relates to a vehicle chassis and a mining dump truck. The vehicle chassis comprises a main vehicle frame, auxiliary vehicle frames and an axle housing, the auxiliary vehicle frames are arranged below the front end and the rear end of the main vehicle frame respectively, and the auxiliary vehicle frame located at the front end of the main vehicle frame and the auxiliary vehicle frame located at the rear end of the main vehicle frame are both connected with the main vehicle frame in a rotating mode. And the rotary motion of the auxiliary frame at the front end relative to the main frame and the rotary motion of the auxiliary frame at the rear end relative to the main frame are independently controlled. The auxiliary frame at the front end is hinged to the axle housing located at the front end of the main frame, and a suspension system is installed between the auxiliary frame at the front end and the axle housing at the front end. The auxiliary frame at the rear end is hinged to the axle housing located at the rear end of the main frame, and another suspension system is installed between the auxiliary frame at the rear end and the axle housing at the rear end. By optimizing the structural layout of the vehicle chassis, front and rear tires can be independently controlled to steer, the vehicle chassis can run in two directions, the turning radius is reduced, and damage to a frame and an axle housing caused by frequent steering is reduced.
本发明属于车辆底盘技术领域,具体涉及一种车辆底盘及矿用自卸车。车辆底盘包括主车架、副车架和桥壳,主车架的前后两端的下方各设有一副车架,位于主车架前端的副车架和位于主车架后端的副车架均与主车架回转连接,且前端的副车架相对主车架的回转运动以及后端的副车架相对主车架的回转运动均采用独立控制。前端的副车架与位于主车架前端的桥壳间铰接,且前端的副车架与前端的桥壳间安装有悬架系统;后端的副车架与位于主车架后端的桥壳间铰接,且后端的副车架与后端的桥壳间安装有另一悬架系统。本发明通过对车辆底盘的结构布局优化,使得前后轮胎均可以独立控制转向及车辆底盘能够双向行驶,减小了转弯半径,降低频繁转向对车架、桥壳的损伤。
