<p>Disclosed are a driving device and a grader using the same. The driving device comprises an engine (1), a hydraulic pump (2), hydraulic motors (3), drive wheels (5) and an assembly (4) of a speed change axle and balance boxes. The power input ends of the assembly (4) are connected to the power output ends of the hydraulic motors (3), and the power output ends of the assembly (4) are connected to the drive wheels (5). The driving device can realize continuously variable speed ratios within a certain range, and has certain load self-adaptability and large speed adjustment range. By utilizing mechanical synchro means, the left and right drive wheels have excellent synchronization performance.</p> |
