Auxiliary motor drive system

An auxiliary motor direct drive system for installation in a vehicle having an engine, a gear ratio selection mechanism, at least one drive wheel for propelling the vehicle, and a drive train transferring torque from the gear ratio selection mechanism to the drive wheel, said auxiliary motor drive system comprising:

• an auxiliary motor operably engageable to the main drive train of the vehicle intermediate the gear ratio selection mechanism and the drive wheel, so as to be capable of imparting torque to the drive wheel;
• and
• a driving device mountable in the vehicle, said driving device being operably engageable with and dependent upon the engine of the vehicle so as to derive power therefrom, said driving device being operably connected to said auxiliary motor so as to in turn power said auxiliary motor, effecting a substitution to the gear ratio selection mechanism,
• whereby when said auxiliary motor drive system is installed in the vehicle and said driving device is engaged to the engine so as to derive power therefrom, said auxiliary motor is engaged to the drive train so as to impart torque thereto at output requirements, and said driving device is powering said auxiliary motor by shifting the gear ratio selection mechanism to a neutral position, thus bypassing the gear ratio selection mechanism, the vehicle can cruise at a user selected vehicle speed with the engine running at a first engine speed that is lower than and in place of a second engine speed, the engine being required to run at the second engine speed to maintain the vehicle at the user selected vehicle speed when said auxiliary motor drive system is not being used.
