Track drive refers to the mechanism that propels a tracked vehicle, such as a bulldozer, tank, or excavator, by rotating its tracks. The track drive consists of a drive motor, transmission, and differential, which work together to convert the rotary motion of the motor into linear motion of the tracks. The drive motor provides the power, the transmission controls the speed and direction of the tracks, and the differential splits the torque between the two tracks and allows them to rotate at
different speeds, which is necessary for turning. The track drive is a critical component of tracked
vehicles as it provides the necessary propulsion and mobility to perform various tasks in rough or
uneven terrain.
The special feature of this drive is that this is a typical planetary Gear Box with input and output
from the same side of the gear box. Normally, they have in built negative wet Braking consisting of
spring loaded Sintered and steel Discs. The brake gets release by Hydraulic Pressure.
These are also known as wheel Drives or Sprocket Drives.
