Patent ID: 7210375

Claim:
A transmission unit, comprising: a transmission input shaft and a transmission output shaft; a base transmission disposed between the transmission unit input shaft and the transmission unit output shaft; an angular drive which is connected with an output drive of the base transmission in at least indirectly rotation-proof manner; the angular drive comprising at least one bevel gear step including a first bevel gear and a second bevel gear, where the second bevel gear is coupled to the transmission output shaft in an at least indirectly rotation-proof manner; a transmission case for the base transmission and the angular drive including a base transmission case assigned to the base transmission and a unitary case assigned to the angular drive; the second bevel gear supported in the unitary case; the unitary case being connected locked with the transmission case whereby fasteners and through openings on the base transmission case and on the unitary case for connecting the base transmission and unitary cases are configured such that the base transmission and unitary cases are selectively rotatable relative to each other in the circumferential direction of the transmission unit when unlocked so as to realize various arrangements for the second bevel gear and thus the angular drive relative to a selected installed position of the transmission unit and thus of the base transmission case relative to the installed position of the transmission unit.
