Abstract
A friction drive for a vehicle wherein a friction drive wheel is mounted to engage frictionally the pneumatic tire constituting the periphery of a vehicle traction wheel, such drive wheel being carried on a strut mounted to swing about an axis remote therefrom and which is parallel to and spaced from the axis of the traction wheel in an arrangement such that the strut is subjected to a reaction torque in response to driving friction force in one direction which in turn urges the center of the drive wheel towards the center of the ground wheel. The drive wheel is of lesser diameter than the traction wheel so as to effect a reduction in rate of rotation, and is of frusto-conical configuration so that a variation in drive ratio can be driven by a storage battery powered direct current motor, with the batteries carried either on the vehicle or on a trailer towed thereby.
