Vehicle transmissions

摘要

A vehicle transmission includes a transmission input and output along with a main shaft and a countershaft that create a plurality of transmission ratios for providing different gears when combined. The vehicle transmission also includes a range change transmission. The vehicle transmission also has, in the direction of the propulsion power flow from the transmission input to the transmission output, a performance interface downstream of the countershaft and upstream of the range change transmission for connecting an electric motor.

1. A vehicle transmission comprising:
a transmission input; a transmission output; a main shaft and a countershaft that together form a plurality of transmission ratios for providing different gears, wherein the countershaft can be shifted by at least one or at least two parallel gear ratios that are optionally shiftable in drive connection with the transmission input; and a range change transmission including at least two range-change unit transmissions that are different from one another, by means of which the main shaft can be shifted optionally into a drive connection with the transmission output; wherein a performance interface for connecting an electric motor is provided in a direction of a propulsion power flow from the transmission input to the transmission output downstream of the countershaft and upstream of the range change transmission; wherein on at least one of the countershaft and the main shaft, selector sleeves are provided, wherein using the selector sleeves, the transmission ratios for providing the different gears can be optionally engaged and disengaged, wherein at least the last selector sleeve of the selector sleeves viewed in the axial direction of the vehicle transmission from the transmission input to the transmission output can be shifted between at least three shift positions, wherein in a first shift position the main shaft is in a drive connection with the countershaft for developing a reverse gear, in a second shift position the at least one of the main shaft and the countershaft is in a drive connection with the electric motor, and in a third shift position the drive connection via the last selector sleeve is interrupted.
