The invention discloses a front suspension system, a chassis and a mining heavy-load dump truck. The front suspension system comprises a front plate spring assembly, a telescopic shock absorber, a transverse pull rod and a longitudinal thrust rod. The two front plate spring assemblies are arranged on the two sides of the vehicle in the transverse direction, the middle areas of the front plate spring assemblies are fixed to a front axle, and the two longitudinal ends of the front plate spring assemblies and a vehicle frame are fixed together. The two telescopic shock absorbers are arranged in the middle areas of the outer side faces of the two front plate spring assemblies in the transverse direction, the tops of the telescopic shock absorbers are connected with a frame, and the bottoms of the telescopic shock absorbers are connected with a front axle. The tie rod is arranged between the two front plate spring assemblies, one end of the tie rod is connected with the frame, and the other end of the tie rod is connected with the front axle. The two longitudinal thrust rods are arranged on the two sides of the vehicle in the transverse direction, one end of each longitudinal thrust rod is connected with the vehicle frame, and the other end is connected with the front axle. The device is simple in structure and high in reliability, multi-direction restraining and elastic damping functions are achieved, vibration of a whole vehicle in multi-direction restraining and limiting and vibration of a frame and a vehicle body can be limited, and the comfort and the reliability of the whole vehicle are improved.

    本发明公开了一种前悬架系统、底盘及矿用重载自卸车,包括前板簧总成、筒式减震器、横拉杆和纵向推力杆;两个前板簧总成布置在车辆横向方向的两侧,前板簧总成的中部区域固定在前车桥上,前板簧总成的两个纵向端部与车架固定在一起;两个筒式减震器布置在两个前板簧总成的横向方向外侧面中部区域处,且其顶部与车架相连,底部与前车桥相连;横拉杆布置在两个前板簧总成之间,其一端与车架相连,另一端与前车桥相连;两个纵向推力杆布置在车辆横向方向的两侧,其一端与车架相连,另一端与前车桥相连。本发明结构简单,可靠性强,满足多方向约束及弹性减震功能,并能限制整车在多方向约束限位及车架车身的振动,提高整车舒适性和可靠性能。
