Preferably, the motor is gerotor motor.

Preferably, described that side of 5th bearing set away from the casing is provided with second bearing capping, described second Bearing is covered is combined with outside framework oil seal between the output shaft.

Preferably, the pushing meanss are hydraulic jack or cylinder.

This transfer case feature：

First, driving gear and the first driving gear are connected on band spline final drive shaft simultaneously by internal spline, and with master Power transmission shaft keeps identical angular speed, and driven gear and the first driven gear are fixed on output shaft by bearing.

2nd, driving gear and driven gear are engaged all the time, and the first driving gear and the first driven gear are engaged all the time.

3rd, change-speed gearing is remained with output shaft is rigidly connected and synchronous with output rotating speed holding.

4th, speed change change gear is in middle position, when motor rotates, and motor universal driving shaft drives final drive shaft rotation, now, driving tooth Wheel is contacted with driven gear by resistance F, but due to studding with drive bearing inside driven gear, so, driven gear is with actively Gear and rotate, transfer case is without output.

5th, speed change change gear is in high speed or 1:1 gear（High speed or 1 are designed as needed:1 constant speed gear）When, speed change change gear Engaged with driven gear, driven gear is engaged with driving gear, motor rotation drives final drive shaft rotation, output shaft is by becoming Fast change gear, driven gear, driving gear rotate with motor.

6th, fast change gear is in low gear（Gearratio is designed as needed）When, speed change change gear is engaged with the first driven gear, First driven gear is engaged with the first driving gear, motor rotation, drive final drive shaft rotation, output shaft by speed change change gear, First driven gear, the first driving gear rotate with motor.

The beneficial effects of the utility model are：

The main drive gear connected on final drive shaft by internal spline is connected with driven gear, then is transferred to by transition gear Output shaft, most the output of motor is transferred to the structure design of output shaft at last.

Using bearing-free gerotor motor, gerotor motor procapsid internal structure is transplanted to inside transfer case housing, horse is used The universal driving shaft reached is directly connected with the final drive shaft of transfer case, sets the structure that motor forms organic whole with transfer case Meter；

This transfer case uses bearingless motors, and the universal driving shaft of motor is directly connected with the final drive shaft of transfer case, makes motor Organic whole is formd with transfer case, installation volume is smaller.

In the case where keeping transfer case support strength constant, the manufacturing cost and supporting motor of transfer case are reduced Cost, more energy efficient environmental protection.

This transfer case can be final to realize with supporting single-speed motors, double-speed motor and single speed or double speed motor with brake Output shaft double speed, four-speed and braking effect.
