Abstract
The present invention is directed to a motor mechanism provided with first and second motor units as well as a differential gear unit. The differential gear unit is provided with three rotating members which are engaged mutually and rotate in constant differential ratio rates. One of the rotating shafts is provided in one of the motors, and a second of these rotating shafts is provided in the second motor. A differential pinion gear rotation axle shaft corresponds to the third rotating shaft. The differential gear unit will cause a drive axle shaft to rotate. The rotating shaft of the first motor rotates at a differential speed with respect to the rotating shaft of the second motor which is due to the difference of revolution between the differential gear axle and the revolution of the rotating shafts of both first and second motors.
Claims17
A motor mechanism comprising a first motor;
- a second motor;
- and a differential gear unit;
- wherein the differential gear unit essentially consists of three rotating members which are engaged mutually and rotate in constant differential ratio rates;
- the differential ratio being determined by the ratio of tooth numbers of gears mutually engaged;
- a rotating shaft of the first motor corresponds to one of three members of the diferential gear unit;
- a rotating shaft of the second motor corresponds to the other one of three members of, the diferential gear unit;
- a differential pinion gear rotation axle shaft corresponding to the another of three members of the diferential gear unit will empower a drive axle shaft;
- and further, the rotating shaft of the first motor rotates in the differential speed with the rotating shaft of the second motor;
- the difference of the revolution which is proportional to the difference between the revolution of the differential gear axle and the revolution of the rotating shaft of the first motor is generated between the revolution of differential gear axle and the revolution of the rotating shaft of the second motor so that when the difference is 0, the shafts of the first motor and second motor and the differential gear axle turn at the same rotation speed;
- each of the first and second motors has a drive and regenerative switching means which switches to connect to a source or a regenerator in accordance with a given pattern, thereby the first and second motors function as a driving motor or a generator, in accordance with given pattern signals.
