摘要:
A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.

A multi-stage automatic transmission comprises a drive input shaft (AN), a drive output shaft (AB), three planetary gearwheel assemblies (RS1, RS2, RS3) arranged next to one another in series and five shift control elements (A to E). A sun gearwheel (SO3) of the third planetary gearwheel assembly (RS3) can be fixed relative to a transmission housing (GG) by means of the first shift control element (A). The drive input shaft (AN) is connected to a sun gearwheel (SO2) of the second planetary gearwheel assembly (RS2) and can be connected via the second shift control element (B) to a sun gearwheel (SO1) of the first planetary gearwheel assembly (RS1) and/or via the fifth shift control element (E) to a web (ST1) of the first planetary gearwheel assembly (RS1). Alternatively, the sun gearwheel (SO1) of the first planetary gearwheel assembly (RS1) can be fixed via the third shift control element (C) and/or the web (ST1) of the first planetary gearwheel assembly (RS1) via the fourth shift control element (D) relative to the transmission housing (GG). The drive output shaft (AB) is connected to an annular gearwheel (HO1) of the first planetary gearwheel assembly (RS1) and to one of the webs (ST2, ST3) of the second or third planetary gearwheel assemblies (RS2, RS3). The second and fifth shift control elements (B, E) form a structural group, each with a disk pack (200, 500), and each with a servo device (210, 510), and a disk support (ZYLBE) common to the two shift control elements (B, E). The disk pack (200) of the second shift control element (B) has a larger diameter than the disk pack (500) of the fifth shift control element (E).

摘要:
A multistage transmission with a drive shaft (3) is connected with a shiftable primary planetary gear set (10), having an output shaft (4), connected with a shiftable principal planetary gear set (20) and being provided with a plurality of shifting elements (A to F), via selective closings of at least six forward gear stages, without group shifting, can be attained. One output element of the primary planetary gear set (10), via a first shifting element (A), can be connected with a first input element of the principal planetary gear set (20) and via a second shifting element (B) can be connected with a second input element of the principal planetary gear set (20). The input drive shaft (3) is, via a fifth shifting element (E), connectable with a third input element of the principal planetary gear set (20). Advantageously, a sun gear (11) of the primary planetary gear set (10) is fixed in location, via a sixth shiftable element placed on that side of the primary planetary gear set (10) which is remote from the principal planetary gear set (20). The primary planetary gear set (10) is designed as a plus-transmission with inner and outer planet gears (12, 13), the spiders thereof being bound together.

摘要:
A clutch system for a transmission with one clutch (1) which comprises one disc carrier (3) and one servo mechanism (10) situated within the disc carrier (3) with dynamic pressure balance for actuating the clutch (1) and with a planet carrier of a planetary gear set (26) the spider plate (27) of which abuts in axial direction on a pressure balance space (15) of the dynamic pressure balance of the servo mechanism (10). It is proposed that the spider plate (27) be non-torsionally connected with the disc carrier (3) and be axially fixed via a locking element (31) on the disc carrier (3) in a manner such that the servo mechanism (10) is prestressed against the disc carrier (3) by the axial fixing of the spider plate (27).

A clutch arrangement in a transmission, particularly in an automatic transmission or automated selector transmission in the design of a double clutch transmission, having two axially and radially adjacent multi-disc clutches (B, E) in which an inner discs (23) of the radially inner clutch (E) are situated upon an inner disc carrier (37) and an outer discs (21) of the radially outer clutch (B) upon an outer disc carrier (38) while an inner discs (22) of the radially outer clutch (B) and an outer discs (24) of the radially inner clutch (E) are situated upon a common disc carrier (9). It is further provided that discs (23, 24) of radially inner disc set (40) axially support themselves against a guard ring (16) fastened on the common disc carrier (9). To achieve a clutch arrangement that spares space and is economical, it is proposed that the discs (21, 22) of a radially outer disc set (39) can be axially pressed against a contact section (7) of the common disc carrier (9) which consists of a radially outwardly pointing end piece of the common disc carrier (9).
