Abstract
The power train of a motor vehicle has an engine which normally drives the wheels and can be started by an electric motor which acts as a generator once the engine is started. The torque transmitting connection between the crankshaft of the engine and a shaft of the motor includes a planetary and one or more freewheels of the type employing an elongated belt surrounding a rotary part and being surrounded by the internal surface of a hollow part. The belt or belts can be urged into or released from frictional engagement with one of the adjacent surfaces by centrifugal force and/or by an electromagnet.
Claims20
A power train, for use in motor vehicles, comprising:
- a variable-speed prime mover machine having a rotary element;
- at least one electrical machine;
- and
- means for transmitting torque between said rotary element and said at least one electrical machine, including
- a planetary, and
- at least one engageable and disengageable freewheel between said planetary and said at least one electrical machine and including an elongated band having a first friction surface engageable with a first complementary surface provided on a rotary component of one of said planetary and said one machine and a second friction surface engageable with a second complementary surface on a component of the other of said planetary and said one machine, one of said components being rotatable relative to the other of said components when at least one of said friction surfaces is disengaged from the respective complementary surface.
