The invention discloses an auxiliary parking braking system of a heavy wide-body mining dump truck, which comprises: a two-section transmission shaft which is arranged between a transmission and an intermediate axle for transmission, and includes a first transmission shaft and a second transmission shaft which are connected with each other, a brake disc which is arranged at the joint of the first transmission shaft and the second transmission shaft in a sleeving manner, wherein the brake disc is fixedly connected with the first transmission shaft and the second transmission shaft through connecting pieces; and a brake control mechanism which is fixed on the frame cross beam and is used for controlling the brake disc to implement and release braking. The auxiliary parking system is arranged at the joint of the two-section type transmission shaft, the needed braking torque is small, and the space of the wheel side is not occupied; while the weight is reduced, the space at the wheel edge of the axle is larger, and the arrangement space structure and the performance of the suspension are further optimized.

    本发明公开一种重型宽体矿用自卸车的辅助驻车制动系统,包括两节式传动轴设置于变速器和中桥之间用于传动,包括相连接的第一传动轴和第二传动轴;制动盘套设设置在所述第一传动轴和第二传动轴的连接处,所述制动盘通过连接件与所述第一传动轴和第二传动轴连接固定;制动控制机构固定在车架横粱上,用于控制所述制动盘实施和解除制动。本发明在两节式传动轴的连接处设置辅助驻车系统,所需的制动力矩较小,且不占用轮边的空间;在轻量化的同时使得车桥轮边处的空间更大,悬架布置空间结构及性能进一步优化。
