Abstract
A differential having a driving member; an input member; first and second rotatable output members; differential gearing operable between the input member and the first and second output members, for transmitting rotation from the input member to the first and second output members and providing for differential rotation of the first and second output members relative to one another; an engaging device operable to establish a driving connection between the driving member and the input member; an inhibiting device operable to inhibit relative rotation between the first and second output members; and an actuating device for causing the operation of the engaging device and the inhibiting device.
Claims20
A differential comprising:
- a driving member;
- an input member;
- first and second rotatable output members;
- differential gearing operable between the input member and the first and second output members, for transmitting rotation from the input member to the first and second output members and providing for differential rotation of the first and second output members relative to one another;
- an engaging device operable to establish a driving connection between the driving member and the input member;
- an inhibiting device operable to inhibit relative rotation between the first and second output members;
- and
- an actuating device for operating the engaging device and the inhibiting device.
A motor vehicle including:
- a first pair of wheels and a main drive system for driving the first pair of wheels, a second pair of wheels and an auxiliary drive system for driving the second pair of wheels, the auxiliary drive system including an electric motor and a differential, the differential comprising:
- a driving member;
- an input member, drivable by the motor by way of the driving member;
- first and second rotatable output members for connection to respective wheels of the second pair of wheels of the vehicle;
- differential gearing operable between the input member and the first and second output members, for transmitting rotation from the input member to the first and second output members and providing for differential rotation of the first and second output members relative to one another;
- an engaging device operable to establish a driving connection between the driving member and the input member;
- an inhibiting device operable to inhibit relative rotation between the first and second output members;
- and
- an actuating device for operating the engaging device and the inhibiting device.
An auxiliary drive system for wheels of a motor vehicle, the system including a motor and a differential, the differential comprising:
- a driving member;
- an input member, drivable by the motor by way of the driving member;
- first and second rotatable output members for connection to respective wheels of the vehicle;
- differential gearing operable between the input member and the first and second output members, for transmitting rotation from the input member to the first and second output members and providing for differential rotation of the first and second output members relative to one another;
- an engaging device operable to establish a driving connection between the driving member and the input member;
- an inhibiting device operable to inhibit relative rotation between the first and second output members;
- and
- an actuating device for operating the engaging device and the inhibiting device.
