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.
Claims22
A vehicle comprising:
- a pair of electric wheel motors disposed on the vehicle;
- a generator clutch-brake assembly drivingly engaged with a prime mover, and in electrical connection with the pair of electric wheel motors, the generator clutch-brake assembly comprising:
- a generator housing comprising an upper housing member and a lower housing member, the lower housing member having an external surface;
- a field coil mounted to the external surface of the lower housing member;
- a brake shroud engaged to the external surface of the lower housing member;
- a clutch rotor disposed between and rotatable relative to the field coil and the brake shroud;
- a magnetic clutch-brake disk disposed between the clutch rotor and the brake shroud, the clutch-brake disk being selectively engageable with the clutch rotor when the field coil is energized and with the brake shroud when the field coil is de-energized;
- and
- an output hub engaged with the clutch-brake disk;
- and
- a belt and pulley system engaged to and powered by the output hub, the belt and pulley system driving a plurality of mowing blades mounted on the vehicle.

A vehicle comprising:
- an electric motor drivingly engaged to a driven wheel;
- and
- a generator clutch-brake assembly drivingly engaged with a prime mover and in electrical connection with the electric motor, and comprising:
- a generator housing member having an external surface;
- a field coil mounted to the external surface;
- a brake shroud secured to the external surface;
- an adjustment mechanism to permit a distance of the brake shroud to the external surface of the generator housing member to be varied;
- a clutch rotor disposed between and rotatable relative to the field coil and the brake shroud;
- a magnetic clutch-brake disk disposed between the clutch rotor and the brake shroud, the clutch-brake disk being selectively engageable with the clutch rotor when the field coil is energized and with the brake shroud when the field coil is de-energized;
- and
- an output hub engaged with the clutch-brake disk.
8 more elements
A vehicle comprising:
- a frame having a longitudinal axis extending from a front of the frame to a rear of the frame;
- a pair of electric wheel motors;
- a prime mover having an output shaft, the output shaft having a first axis;
- a generator clutch-brake assembly comprising:
- a clutch-brake assembly supported by a housing member and comprising:
- an input tube receivingly engaged with the output shaft, the input tube having a second axis;
- a brake shroud engaged to the housing member;
- a field coil mounted to the housing member;
- a clutch rotor connected to the input tube between the field coil and the brake shroud;
- a clutch-brake disk between the clutch rotor and the brake shroud to selectively engage the clutch rotor when the field coil is energized and to engage the brake shroud when the field coil is de-energized;
- and
- an output hub connected to the clutch-brake disk;
- and
- a generator assembly connected to the pair of electric wheel motors and comprising a housing and a drive shaft drivingly engaged with the input tube, the drive shaft having a third axis that is parallel to and offset from the second axis, wherein the housing member forms part of the housing of the generator assembly;
- and
- a belt and pulley system connected to the output hub and driving at least one mowing blade.
