Abstract
In a transmission system for an automotive vehicle, a planetary gear (3) comprises a ring gear (33) fixed to a housing, the planetary gear being interposed between a drive axle (1) in which a torque is transmitted from a power source (EG) of the vehicle and an output axle (2) via which the transmitted torque is outputted, a first clutch (A-C/L) is interposed between a carrier (32) of the planetary gear and the drive axle (1), a second clutch (B-C/L) is interposed between the carrier (32) of the planetary gear and the output axle (2), and a third clutch (C-C/L) is interposed between a sun gear (31) of the planetary gear and the drive axle (1).
Claims20
A transmission system for an automotive vehicle, comprising:
- a planetary gear comprising a ring gear fixed to a housing, the planetary gear being interposed between a drive axle in which a torque is transmitted from a power source of the vehicle and an output axle via which the transmitted torque is outputted;
- a first clutch interposed between a carrier of the planetary gear and the drive axle;
- a second clutch interposed between the carrier of the planetary gear and the output axle;
- and
- a third clutch interposed between a sun gear of the planetary gear and the drive axle.
A method applicable to a transmission system for an automotive vehicle, comprising:
- interposing a planetary gear between a drive axle in which a torque is transmitted from a power source of the vehicle and an output axle via which the transmitted torque is outputted, the planetary gear comprising a ring gear fixed to a housing;
- interposing a first clutch between a carrier of the planetary gear and the drive axle;
- interposing a second clutch between the carrier of the planetary gear and the output axle;
- and
- interposing a third clutch between a sun gear of the planetary gear and the drive axle.
