Abstract
A generator and clutch assembly is disclosed for use in a vehicle and includes a rotatable input, an electric generator in a generator housing, a clutch rotor by driven by the rotatable input, and an electric clutch and brake assembly which may be integrated with the generator housing. A field coil may be mounted to an external surface of the generator housing. The generator and clutch may be offset and connected by means of a transfer system having a transfer housing, wherein a field coil is mounted to an external surface of the transfer housing.
Claims20
A generator and clutch assembly, comprising:
- a rotatable input member having an axis of rotation;
- an electric generator comprising a generator housing having an upper housing member and a lower housing member, a stator disposed in the generator housing and having a coil formed therein, and a first rotor disposed in the generator housing and having a first magnet affixed thereto, wherein the first rotor is engaged to and driven by the rotatable input member, whereby the first magnet and the coil generate an electrical output;
- a clutch rotor driven by the rotatable input member;
- an electric clutch and brake assembly integrated with the generator housing, the electric clutch and brake assembly comprising:
- a field coil mounted to an external surface of the lower housing member of the generator housing, and adjacent to the clutch rotor;
- a brake shroud fastened to the external surface of the lower housing member;
- and
- a clutch-brake disk fixed to an output hub and being axially movable along the axis of rotation of the rotatable input member, the clutch-brake disk having a first side to engage the brake shroud and provide a braking force to the output hub and a second side, opposite the first side, to engage the clutch rotor, whereby, when the field coil is energized, a magnetic force moves the clutch-brake disk into a position whereby the second side engages the clutch rotor to provide a rotational force to the output hub.

A generator and clutch assembly for use in a vehicle having a prime mover, the generator and clutch assembly comprising
- an input tube having a proximal end, a distal end, and a clutch rotor integrally formed therewith between the proximal end and the distal end, wherein the input tube is powered by the prime mover and has a first axis of rotation;
- an electric generator comprising a generator housing and a generator drive shaft having a proximal end, a distal end, and a second axis of rotation that is parallel to the first axis of rotation;
- a transfer system comprising a transfer housing and connecting the input tube to the generator drive shaft;
- an electric clutch and brake assembly comprising:
- a field coil mounted to an external surface of the transfer housing, and adjacent to the clutch rotor;
- a brake shroud fastened to the external surface of the transfer housing;
- and
- a clutch-brake disk fixed to an output hub adjacent to the distal end of the input tube and being axially movable along the first axis of rotation, the clutch-brake disk comprising a first side to engage the brake shroud and provide a braking force to the output hub, and a second side, opposite the first side, to engage the clutch rotor, whereby, when the field coil is energized, a magnetic force moves the clutch-brake disk into a position whereby the second side engages the clutch rotor to provide a second rotational force to the output hub.

A generator and clutch assembly for use in a vehicle having a prime mover driving an output shaft, the generator and clutch assembly comprising:
- a first rotatable member having a first axis of rotation and driving a clutch rotor;
- an electric generator comprising a generator housing having an upper housing member and a lower housing member, and a second rotatable member having a second axis of rotation that is parallel to the first axis of rotation;
- an electric clutch and brake assembly comprising a field coil, a brake shroud, and a clutch-brake disk fixed to an output hub adjacent to a distal end of the first rotatable member and being axially movable along the first axis of rotation, the clutch-brake disk comprising a first side to engage the brake shroud and provide a braking force to the output hub, and a second side, opposite the first side, to engage the clutch rotor, whereby, when the field coil is energized, a magnetic force moves the clutch-brake disk into a position whereby the second side engages the clutch rotor to provide a rotational force to the output hub;
- and
- a transfer system to rotatably connect the first rotatable member to the second rotatable member and comprising a transfer housing, wherein the field coil is mounted to an external surface of the transfer housing.
