Abstract:
An arrangement comprising a first shaft (9) and a planetary gear arrangement (24) which comprises at least one sun gear (25), several planetary gears (26) supported by a planetary gear carrier and at least one ring gear (27), wherein:a) said planetary gears (26) are each rotatably supported on a respective stud (29),b) each said stud (29) is supported by a first and second planet spiders (28, 47) with which said studs (29) and said first and second planet spiders (28, 47) jointly form the planetary gear carrier,c) said planetary gears (26) engage both said sun gear (25) and said ring gear (27),d) said first shaft (9) drives said first planet spider (28),e) said ring gear (27) supports an internal brake multi-disc carrier (35) of a brake (34). and said stud (29) supports an internal clutch multi-disc carrier of a clutch (46),f) said clutch (46) and said brake (34), each consist of said internal disc carrier and an external disc carrier,g) internal discs are coordinated with said internal disc carrier and external discs with said external disc carrier,h) said internal discs and said external discs are movable in an axial direction and selectively connected with said internal and external disc carriers,i) said clutch (46) and said brake (34) are each engaged by a piston pressing said external and internal discs against an end disc which is an external disc,j) said clutch (46) and said brake (34) are each disengaged by said piston being returned to an initial position by a resetting devices, andk) said external carrier (36) of brake (34) has teeth (42) on an external periphery thereof,l) said external disc carrier (36) is fixed circumferentially by said teeth (42) and fixed in an axial direction, by a guard ring (43), andm) an end disc (40) of said brake (34) has a collar (44) extending radially toward said first shaft (9), and said collar (44) is closer to said first shaft (9) than an exterior surface of said internal disc carrier (35) of said brake (34).
