Abstract

The invention provides an arrangement structure of a bulldozer transmission system and a bulldozer, and belongs to the field of electric transmission bulldozers. A power device of the electric transmission system is mounted on the main frame on the front side of the rear axle box; a rectifying device of the electric transmission system is installed on the rear end face of the rear axle box, and the input and output ends face downwards. A high-voltage cable led out from the output end of the power device penetrates through a flange preset on the rear axle box to enter the rear axle box, then is arranged along the outer surface of the transmission roller and finally is connected to the input end of the rectifying device. The rectifying device is arranged on the rear end face of the rear axle box, so that daily inspection and fault maintenance of the rectifying device become convenient and rapid; moreover, the high-voltage cable between the power device and the rectifying device is hidden in the rear axle box, the wiring structure is simplified through independent wiring arrangement, and signal interference and maintenance difficulty caused by disordered lines are avoided.
