The final drive consists of a walking motor (plunger type, which converts hydraulic energy into rotational kinetic energy) and a deceleration part (two-stage gear reduction). There are two final drives on the machine, left and right, which directly drive the crawler to enable the machine to move forward. Back and turn.
The motor is very similar in structure to the pump. As the power output device of the hydraulic system, it does not push hydraulic oil like a pump.
Instead, it is pushed by high-pressure hydraulic oil and generates torque and continuous rotational movement.
The deceleration part of the final drive is mainly decelerated by two-stage planetary gears.
