Transmission distribution for vehicles with front and rear wheel drive

摘要

The transmission distribution (10) has a rotary input shaft (14) and first and second output shafts (15,18). The first output shaft (15) is so connected that it drives one of the shafts (20,17). The second output (18) drives the other shaft of the set (17,20). A differential (35) has a shaft (36) which can be driven by the input shaft and which has a first output (40) which drives the first output shaft. This shaft has a second output (42,43) which drives the second output shaft. A first and second coupling (45,46) can be selectively operated to drive the outputs of the differential which rotate as one unit, while the input of the differential transmits torque to the first output shaft without transmitting torque to the second output shaft when the first coupling is completely disengaged and the second coupling is completely made. The outputs of the differential can be driven independently from one another. The input of the differential can transmit torque to both outputs when the first coupling is completely made and the second coupling is completely disengaged so that both shafts (17,20) are driven.
