Abstract

The invention relates to a loading machine power system, a control method thereof and a loading machine. The power system comprises a frame (2), four wheels (1), four driving parts (3) and two steering oil cylinders (4); a front frame body (21) and a back frame body (22) are rotatably connected through a pin shaft (23) in a horizontal plane; the four driving parts (3) are in driving connection with the four wheels (1) and have different driving modes according to the working conditions of the loading machine; and the two steering oil cylinders (4) are arranged on the left side and the right side of the frame (2), and the two ends of the steering oil cylinders (4) are connected with the front frame body (21) and the back frame body (22) respectively. According to the system, a mechanical transmission structure can be simplified, the appropriate driving modes are selected according to the working conditions of the loading machine, and not only can the power system have the higher transmission efficiency, but also power can be better saved; and large steering driving force can be provided for the loading machine through the steering oil cylinders, and under cooperation with differential driving of the wheels, a whole vehicle can stably and efficiently steer, and tire wear can be reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a loader power system, a control method thereof, and a loader. Background technique [0002] Vehicles can adopt centralized electric drive and distributed electric drive. At present, most vehicles are equipped with a drive motor on the front axle and rear axle respectively, and the drive system transmits the power of the drive motor to each wheel; and distributed electric drive The drive can be equipped with a drive motor on the front axle and rear axle respectively. In order to meet the steering requirements, a mechanical differential is installed between the two wheels on the same axle, and devices such as steering tie rods are used to provide steering driving force. [0003] The transmission structures corresponding to these driving methods are relatively complex, occupy a large space layout, and have low transmission efficiency, which makes it difficult to meet the work r...
