Abstract
A drive system having a power input subsystem which operates and regulates the input power to the drive system in response to the demand placed thereon, and apportions the input power in accordance with the individual loads placed on the drive system by separate driven entities.
Claims20
A drive system comprising:
- (a) a first driven entity;
- (b) a prime mover means coupled to drive said first driven entity;
- (c) a second driven entity;
- (d) a power input means;
- (e) a torque apportioning means coupled to receive power from said power input means and coupled to said first and said second driven entities for apportioning power received from said power input means to said first and said second driven entities in accordance with the loads thereon;
- and
- (f) locking means associated with said torque apportioning means for locking thereof to apply the power received from said power input means equally to said first and said second driven entities when the load on said first driven entity becomes less than the load on said second driven entity.

A drive system comprising:
- (a) a driven entity;
- (b) at least one variable speed electric traction motor coupled to drive said driven entity;
- (c) a storage battery means coupled to supply power to said motor;
- (d) a multiposition switch means connected between said motor and said storage battery means for controlling the amount of power supplied to said motor;
- (e) a power input means;
- (f) a generator connected for charging said storage battery means;
- (g) a torque apportioning means having an input shaft coupled to receive power from said power input means and having a first output shaft coupled to assist said motor in driving said driven entity and a second output shaft coupled to drive said generator, said torque apportioning means having gear means for apportioning the power received thereby to said first and said second output shafts in accordance with the loads thereon;
- and
- (h) locking means associated with said torque apportioning means for locking said torque apportioning means so that its first and second output shafts rotate at the same RPM when the load on its first output shaft is equal to or less than the load on its second output shaft.
