Product Information of CTU Planetary Gearbox Track Drive

Brevini Riduttori power transmission compact planetary track drive is designed for Tracked Vehicles: excavators and earth-moving machinery.
They have heavy housings, short overall lengths, and large radial and axial load capacities.
They have an integrated multi-disc fail-safe brake that can be mounted directly on the hydraulic motor and are ready to accept the plug-in hydraulic motor.
The compact design of the device allows power to be transmitted directly from the CZPT axial piston hydraulic motor to the operating machine, thereby reducing the overall size of the hydrostatic transmission.
High radial bearing capacity, particular sealing system, and manual separation allow the final drive to operate under severe and heavy load conditions.
The internal multi-disc parking brake, motion control valve, and smooth displacement variability provided by CZPT hydraulic motor are additional advantages enabling Dana as one partner to provide a complete, reliable, integrated transmission package.

Planetary Gearbox in Track Drive

Continuous track, also known as tank track or track, is a vehicle propulsion system in which two or more wheels drive continuous pedals or track shoes. For military vehicles and heavy equipment, the steel strip is usually made of modular steel plates. For lighter agricultural or construction vehicles, it is made of synthetic rubber reinforced with steel wires.
Compared with the steel or rubber tires on the exact vehicle, the large surface area of the track better distributes the vehicle’s weight so that the continuously tracked vehicle can pass through the soft soil foundation and is unlikely to get stuck due to sinking. The prominent tread of the metal plate is wear-resistant, especially compared with rubber tires. The aggressive tread of the track provides good traction on the soft road surface but may damage the paved surface so some metal tracks can be installed with rubber pads for use on the paved surface.

The continuous track can be traced back to 1770 and is currently commonly used on various vehicles, including bulldozers, excavators, tanks, and tractors. However, the inherent additional traction, low ground pressure, and durability of a continuous track propulsion system can be found on vehicles used in any application.
