An engine shaft drives oppositely rotating bevel gears which can be coupled to a hollow clutch shaft by forward and reverse clutches. The clutch shaft is coupled to the input shaft of a six-speed, change-speed gearbox through a two-stage epicyclic range gear with a direct drive clutch and brakes for engaging the overdrive and underdrive stages, respectively. An epicyclic creep gear can be selectively switched in upstream of the range gear. Thus, a coupling sleeve couples the clutch shaft either to the input of the range gear or to the input sun wheel of the creep gear. Since the creep gear reverses the sense of rotation, a changeover of control of the clutches is effected when the creep gear is engaged. |
