Abstract:
A transmission gear for a motor vehicle comprising:a gear case;a rotatable drive shaft rotatably supported at the gear case, a driven shaft rotatably separated from the drive shaft and also rotatably supported at the gear case;a planetary gear for providing drive connection between the drive shaft and the driven shaft, the planetary gear comprising:a sun wheel non-rotatably connected with the drive shaft;a planet wheel carrier around the sun wheel and rotatable with respect to the sun wheel;at least one planet wheel supported on the planet wheel carrier around the sun wheel, each planet wheel mating with the sun wheel for being rotated with respect to the planet wheel carrier by rotation of the sun wheel;a gear rim rotatable with respect to and mating with the at least one planet wheel;a clutch element axially displaceable along the drive shaft between a first position at which the clutch element couples the planet wheel carrier with the gear case in a torsionally rigid manner and a second position at which the clutch element couples the planet wheel carrier with the driven shaft in a torsionally rigid manner; the clutch element comprises first and second axially spaced, annular clutch wheels and a connection between the spaced clutch wheels, the clutch wheels encompassing the planet wheel carrier.
