Abstract
A power shift transmission, having an input and an output shaft, rotatably and axially immovably mounted and a rotatably mounted intermediate shaft. The input shaft carries first and second gear wheels. The output shaft carries a third gear wheel. The intermediate shaft carries a fourth, fifth, and sixth gear wheels, which are movable such that in a first shifting position the first gear wheel is in engagement with the fourth gear wheel and the sixth gear wheel is in engagement with the third gear wheel, but the second gear wheel and the fifth gear wheel are out of engagement, and in a second shifting position, the second gear wheel is in engagement with the fifth gear wheel and the sixth gear wheel is in engagement with the third gear wheel, but the first gear wheel and the fourth gear wheel are out of engagement.
Claims13
A power shift transmission, comprising:
- a first shaft that is rotatably mounted and axially immovably mounted;
- a second shaft that is rotatably mounted and axially immovably mounted and configured to rotate slower than the first shaft;
- an intermediate shaft that is rotatably mounted;
- a first gear wheel and a second gear wheel arranged on the first shaft;
- a third gear wheel arranged on the second shaft;
- a fourth gear wheel, a fifth gear wheel, and a sixth gear wheel arranged on the intermediate shaft and configured to move as a unit relative to the first gear wheel and second gear wheel and the third gear wheel;
- wherein in a first shifting position providing a first transmission stage:
- the first gear wheel is in engagement with the fourth gear wheel;
- the sixth gear wheel is in engagement with the third gear wheel;
- and
- the second gear wheel and the fifth gear wheel are out of engagement,
- wherein in a second shifting position providing a second transmission stage:
- the second gear wheel is in engagement with the fifth gear wheel;
- the sixth gear wheel is in engagement with the third gear wheel;
- and
- the first gear wheel and the fourth gear wheel are out of engagement,
- wherein at least one of the first and the second shaft transmits a torque of at least 10 kNm,
- wherein a gap is formed between the first gear wheel and the second gear wheel, such that when the first gear wheel and the fourth gear wheel are out of engagement, the second gear wheel and the fifth gear wheel are not yet in engagement,
- wherein the first and second gear positions are consecutive without any other gear wheels therebetween.
