SYSTEM AND METHOD FOR PERFORMING SHUTTLE SHIFTS WITH A TRANSMISSION OF A WORK VEHICLE |
摘要 |
A method for performing a shuttle shift with a transmission of a work vehicle is disclosed, wherein the transmission includes an input shaft, a counter shaft and a plurality of driven shafts extending generally parallel to the input and counter shafts. The method may include disengaging a clutch associated with a first directional gear of a directional shaft of the plurality of driven shafts. The first directional gear may be configured to rotate the directional shaft in a first direction. Additionally, the method may include engaging clutches associated with at least two gears of at least one secondary driven shaft of the plurality of driven shafts to reduce a rotational speed of the directional shaft and, after the rotational speed of the directional shaft is reduced, engaging a clutch associated with a second directional gear of the directional shaft such that the directional shaft rotates in a second direction. |

1. A method for performing a shuttle shift with a transmission of a work vehicle, the transmission including an input shaft, a counter shaft and a plurality of driven shafts extending generally parallel to the input and counter shafts, the method comprising:
disengaging a clutch associated with a first directional gear of a directional shaft of the plurality of driven shafts, the first directional gear being configured to rotate the directional shaft in a first direction; engaging clutches associated with at least two gears of at least one secondary driven shaft of the plurality of driven shafts to reduce a rotational speed of the directional shaft; and after the rotational speed of the directional shaft is reduced, engaging a clutch associated with a second directional gear of the directional shaft such that the directional shaft rotates in a second direction. |
