QATD1404 Tractor Rear Drive Axle
- It consists of the central transmission, planetary terminal transmission, power output, and the braking system. It is a secondary deceleration structure with large output torque.
- The rear axle box body is the whole type. The steel beams on both sides of the frame are respectively connected to the two brake shells of the rear axle box body, and the rear frame is removed and the structure is compact.
- The service brake is wet type, clamp, multi-pieces, steel ball self-reinforcing type, hydrostatic control, and unilateral braking can be implemented; The parking brake is used to control the running brake.
- With differential locks.
- They are integral structures, both the two brake case and the rear axle box.
- Independent type postpositive two-speed standard power-output shaft, 540/1000 rpm, 760/1000 rpm can be selected
- Suitable for 140-horsepower four-wheel drive tractors.
