Abstract
A transmission system has an input connected to a drive source, and an output connected to a load. The transmission system further has a transmission that includes two input shafts and an output shaft, as well as a clutch module comprising a clutch and a planetary gear set which comprises three rotational members of which a first rotational member is connected to the input, a second rotational member is coupled to the output and a third rotational member is connected to a brake. Between the input shafts and the output shaft are located three speed transforming gears and three gear clutches, and between the two input shafts is located a further clutch.
Claims18
A transmission system for a vehicle having a drive source and a load, the transmission system comprising:
- an input which can be connected to the drive source;
- an output which can be connected to the load;
- a transmission comprising a transmission housing, a first input shaft, and an output shaft connected to the output, where a first switchable speed transforming gear is present between the first input shaft and the output shaft;
- a clutch having a first clutch section which is connected to the input, and a second clutch section which is connected to the first input shaft of the transmission;
- and
- a planetary gear set comprising at least three rotational members of which a first rotational member is connected to the input, a second rotational member is coupled to the output, and a third rotational member is connected to a brake, wherein the transmission further includes a second input shaft where a second switchable speed transforming gear is present between the second input shaft and the output shaft, and where the second rotational member of the planetary gear set is connected to the second input shaft.
A transmission system for a vehicle having a drive source and a load, the transmission system comprising:
- an input which can be connected to the drive source;
- an output which can be connected to the load;
- a transmission comprising a transmission housing, a first input shaft (9), and an output shaft connected to the output, where a first switchable speed transforming gear is present between the first input shaft and the output shaft;
- a clutch having a first clutch section which is connected to the input, and a second clutch section which is connected to the first input shaft of the transmission;
- and
- a planetary gear set comprising at least three rotational members of which a first rotational member is connected to the input, a second rotational member is coupled to the output, and a third rotational member is connected to a brake, wherein the transmission further includes a second input shaft where a second switchable speed transforming gear is present between the second input shaft and the output shaft, and where the second rotational member of the planetary gear set is connected to the second input shaft;
- wherein the first and the second rotational members can be coupled directly to each other by means of the clutch and a further clutch or clutches connected in series thereto, without the use of a further speed transforming gear;
- wherein the further clutch or clutches can directly couple the first and the second input shaft of the transmission to each other without the use of a further speed transforming gear.
