ABSTRACT:
A vehicle transmission including a first, a second and a third planetary gear unit coaxially disposed between an input and an output member. The three units have respective first, second and third sun gears, respective first, second and third planetary gears, respective first, second and third carriers, and respective first, second and third ring gears. The first carrier, second ring gear, third sun gear and output members are connected to each other, while the second carrier and the third ring gear are connected to each other. The transmission has a first and a second coupling device for connecting the first ring and sun gears to the input member, respectively, a third and a fourth coupling device for connecting the first sun gear to the second sun gear and to the second carrier and third ring gear, respectively, a fifth coupling device for fixing the third carrier to a stationary member, a sixth coupling device, for fixing the second carrier and third ring gear to the stationary member, and a seventh coupling device for fixing the second sun gear to the stationary member.
