摘要： A powershift transmission of a motor vehicle has a split group with a plurality of powershift stages. An input shaft can be rotatably driven by a drive shaft of a motorized drive and transmits rotational movement in a stepped-up manner to an output shaft of the split group corresponding to one of several powershiftable stage transmissions. The powershiftable stage transmissions can be rotatably driven in a stepped-up manner by the output shaft of the split group via an intermediate group located therebetween, and via an input shaft of a synchromesh transmission group having a plurality of gear stages. A vehicle axle transmission can be rotatably driven by the output shaft of the synchromesh transmission group. The intermediate group has a multiple powershift intermediate transmission, in which each switching position the input shaft of the synchromesh transmission group can be rotatably driven by means of an associated transmission.

摘要： Regarding a travel power transmission apparatus for a tractor, in which a creep speed changing apparatus is housed in a transmission case, the present invention increases a deceleration ratio throughout the creep speed change while suppressing an increase in the size of the transmission case. A creep speed changing apparatus includes: a first power transmission gear that is provided on an output shaft gear of a gear transmission; a first deceleration gear that is supported by a relay shaft so as to be rotatable relative to the relay shaft, in a state of meshing with the first power transmission gear; a second power transmission gear that is provided on the first deceleration gear; a second deceleration gear that is supported by an output shaft of the gear transmission so as to be rotatable relative to the output shaft, in a state of meshing with the second power transmission gear; a third power transmission gear that is provided on the second deceleration gear; a third deceleration gear that is supported by the relay shaft so as not to be rotatable relative to the relay shaft, in a state of meshing with the third power transmission gear; and a pair of deceleration gears that are provided so as to span the relay shaft and the output shaft, and decelerate power from the relay shaft and transmit the resulting power to the output shaft.

摘要： A dual-clutch transmission includes an odd gears clutch, an odd gears shaft supporting at least two odd-numbered rotary gears, an even gears clutch, and an even gears shaft supporting at least two even-numbered rotary gears. A driven rotary shaft is selectively connectable to one respective said odd- or even-numbered gear at a time. The dual-clutch transmission includes first and second range selection gears to transfer drive from the driven rotary shaft to an output shaft so as selectively to permit selection of at least a first range transmission ratio or a second range transmission ratio. The dual-clutch transmission further includes a first bypass drive line to drive engagement of at least two mutually engaged bypass rotary gears with the output shaft, giving rise to a first intermediate transmission ratio.
