The invention relates to the technical field of vehicle chassis, in particular to a double-fork-arm type front suspension and a mining dump truck. The double-fork-arm type front suspension comprises a first control arm, a second control arm, a steering knuckle and a suspension oil cylinder, the first control arm is connected with one end of the steering knuckle through a first ball hinge bearing, the second control arm is connected with the other end of the steering knuckle through a second ball hinge bearing, and the ball hinge bearings are not prone to abrasion or failure. One end of the suspension cylinder is connected with the first control arm, and the other end is connected with the frame; the first control arm and the second control arm are each provided with a mounting part, each mounting part comprises a mounting base, a lubricating sleeve and a space ring, each mounting base is provided with a containing cavity, and each space ring is connected with the corresponding mounting base so that the corresponding lubricating sleeve can be limited in the corresponding containing cavity; a pin shaft is arranged in the lubricating sleeve and used for being fixedly connected with a frame, and the lubricating sleeve rotates relative to the pin shaft. The mounting seat is provided with a first lubricating oil hole, and the lubricating sleeve is provided with a first lubricating oil way to lubricate the pin shaft and reduce abrasion of the pin shaft.

    本公开涉及车辆底盘技术领域,尤其是涉及一种双叉臂式前悬架及矿用自卸车。双叉臂式前悬架包括第一控制臂、第二控制臂、转向节和悬挂油缸,第一控制臂与转向节的一端通过第一球铰接轴承连接,第二控制臂与转向节的另一端通过第二球铰接轴承连接,球铰接轴承不易磨损或失效;悬挂油缸一端与第一控制臂连接,另一端与车架连接;第一控制臂和第二控制臂均设置有安装部,安装部包括安装座、润滑套筒和隔圈,安装座设置有容纳腔,隔圈与安装座连接,以将润滑套筒限位于容纳腔内;润滑套筒内设置有销轴,销轴用于与车架固定连接,润滑套筒相对于销轴转动;安装座设置有第一润滑油孔,润滑套筒设置有第一润滑油路,以对销轴润滑,减少销轴磨损。
