Abstract
A reverse gear set 28, which is adapted to be connected to a second input shaft 16 and to be connected selectively to a first input shaft 11 via a third switching unit 53, is provided in a transmission 20 of a vehicle driving system 1, whereby a reverse driving can be implemented by rotating the first input shaft 11 in a reverse direction to a direction in which the first input shaft 11 rotates for a forward driving by means of power of at least one of an engine 6 and a motor 7, and plural gear of an odd-numbered gear train can be selected by first switching units 51, 61.
Claims7
A vehicle driving system comprising:
- an internal combustion engine;
- an electric motor;
- and
- a transmission mechanism comprising:
- a first input shaft which is connected to the electric motor and which is connected selectively to the internal combustion engine via first engaging and disengaging means;
- a second input shaft which is connected selectively to the internal combustion engine via second engaging and disengaging means;
- an output shaft which outputs power to a driven portion;
- a first gear train which is disposed on the first input shaft and which is made up of a plurality of gears which are connected selectively to the first input shaft via a first switching unit;
- a second gear train which is disposed on the second input shaft and which is made up of a plurality of gears which are connected selectively to the second input shaft via a second switching unit;
- and
- a third gear train which is disposed on the output shaft and which is made up of a plurality of gears which mesh with the gears of the first gear train and the gears of the second gear train, wherein:
- a reverse gear set is provided in the transmission mechanism which is connected to the second input shaft and which is connected selectively to the first input shaft via a third switching unit;
- a reverse driving can be implemented by rotating the first input shaft in a reverse direction to a direction in which the first input shaft rotates to implement a forward driving by means of power of at least one of the internal combustion engine and the electric motor;
- and
- a plurality of gears of the first gear train can be selected by the first switching unit.
