ELECTRIC DRIVE for Off-Highway Vehicles 600028

THE CONCEPT of an electric motor mounted inside the rim of a large wheel provides several advantages: flexibility, weight and cost reductions, and adaptability to established operating and maintenance patterns.
A heavy-duty traction motor drive has been designed that eliminates the need for mechanical drive lines, differentials, and hydraulic torque converters. This paper describes the gear train, lubrication system, brakes, and ventilation of such a drive.
Also discussed is the engine-generator set for an electric wheel motor.*
