Structure Characteristics

1. Combined design of main case and front, rear auxiliary cases, small volume, light weight and high efficiency in power transfer.

2. Twin countershafts, power well distributed and unique structure.

3. Fully synchronized, easy shifting, the main case is equipped with double-taper faced lock-ring synchronizer, large synchro-capacity.

4. Front auxiliary case is equipped with single taper faced lock-ring synchronizer; Rear auxiliary case is equipped with enhanced taper faced lock-pin synchronizer.

5. Rational arrangement for speeds, small ratio steps and good fuel efficiency.

6. Non-metallic friction material is adopted on friction taper surfaces, high reliability.

7. Thin-and-fine teeth design, stable engagement and low noise.

8. There are many types of power taking off.
