Final drives play a crucial role within a machine’s drive train by transferring power to the tires or tracks while providing speed reduction and torque increases. Changing the direction of the power coming from the transmission by 90 degrees allows the axles to be driven.
Cat® Final Drive components must endure incredible torque, high-impact loads, and frequent direction and gear changes. Caterpillar designs and manufactures its final drive components with these demands in mind, using testing processes that simulate real-world applications.
