Patent ID: 7017697

Claim:
A power reverse system, for use with a motorcycle having an engine and a load that includes wheels, to execute power reverse operation, comprising: a motor unit that is rotatable in a positive or negative direction; and specific driveline means, coupled to the motor unit, engine, and load, for starting the engine when the motor unit is rotating in the positive direction, and for executing reverse drive operation of the motorcycle by rotating the wheels of the load in a reverse direction when the motor is rotating in the negative direction, wherein the specific driveline means comprises a primary transmission ratio device ( 109 ) coupled to the engine ( 100 ), a secondary transmission ratio device ( 110 ) coupled to the load ( 111 ), a first one-way driver ( 106 ) coupled between the motor unit ( 101 ) and the primary transmission ratio device ( 109 ), a second one-way driver ( 107 ) coupled between the motor unit ( 101 ) and the secondary transmission ration device ( 110 ), and a clutch ( 108 ) coupled between the primary and secondary transmission ration devices, wherein, when the motor unit ( 101 ) is rotating in the positive direction, the motor unit starts the engine ( 100 ) via the first one-way driver ( 106 ) and the primary transmission ratio device ( 109 ), and wherein, when the motor unit ( 101 ) is rotating in the negative direction, the motor unit drives the load ( 111 ) via the second one-way driver ( 107 ) and the secondary transmission ratio device ( 110 ) so as to perform power reverse operation of the motorcycle.
