Abstract:
1. A vehicle transmission having a continuously variable transmission ratio, said transmission comprising: a CVT variator having first and second variator shafts, an input shaft rotatably engageable with a selected one of the variator shafts, and an output shaft rotatably engageable with a selected one of the variator shafts so that two forward gear ranges with opposite torque transmission directions of the CVT variator are provided, wherein transmission ratio ranges of the variator are constantly contiguous with each other, wherein there are mounted on the input shaft a reverse gear which is rotationally meshed with the first variator shaft through an intermediate gear and which can be coupled in a rotationally fixed connection with the input shaft through a reverse clutch and two forward gears which can be coupled in a rotationally fixed connection with the first variator shaft through a respective forward gear clutch; and two output shaft gears mounted on the output shaft, one of which output shaft gears is rotationally engaged with the first variator shaft and the other output shaft gear is rotationally engaged with the second variator shaft, and which output shaft gears can each be coupled with a respective one of the variator shafts in a rotationally fixed connection through a respective output shaft gear clutch.
