The invention provides a double-fork-arm type front suspension of an off-highway mining dump truck, and belongs to the technical field of automobiles. The front suspension comprises an upper pull rod,an upper fork arm, a pin, a hydro-pneumatic suspension cylinder barrel, a lower fork arm, a bearing seat, a knuckle bearing and a hydro-pneumatic suspension piston rod, the hydro-pneumatic suspensioncylinder is connected with a frame, the upper fork arm and the lower fork arm are hinged to the two sides of the hydro-pneumatic suspension cylinder barrel, and the hydro-pneumatic suspension pistonrod is in sliding connection with the hydro-pneumatic suspension cylinder barrel. The upper pull rod is hinged to the hydro-pneumatic suspension piston rod and the frame. The double-fork-arm type front suspension for the heavy-duty car is simple in structure, the system can adopt hydro-pneumatic suspension with small diameter and stroke, the suspension has the functions of a main pin, an elastic element and a damping element at the same time, the lateral stability of the car is enhanced, and the space utilization rate of a front axle and the flexibility of a steering system are improved.
本发明提供一种非公路矿用自卸汽车的双叉臂式前悬架,属于汽车技术领域。该前悬架包括上拉杆、上叉臂、柱销、油气悬挂缸筒、下叉臂、轴承座、关节轴承及油气悬挂活塞杆,油气悬挂缸与车架连接,铰接安装于油气悬挂缸筒两侧的上叉臂与下叉臂,油气悬挂活塞杆与油气悬挂缸筒滑动连接,上拉杆与油气悬挂活塞杆和车架铰接。本发明提供了一种结构简单的用于重型汽车的双叉臂式前悬架,系统可采用较小直径和行程的油气悬挂,悬挂同时兼具主销、弹性元件和阻尼元件的功能,增强汽车的侧向稳定性,提高了前桥的空间利用率以及转向系统的灵活性。
