A multi-speed transmission has three planetary gear sets and six torque-transmitting mechanism packaged in various ones of five zones within a transmission cavity. Each planetary gear set has a ring gear member, a sun gear member and a carrier member that rotatably supports a plurality of pinion gears that intermesh with both the sun gear member and the ring gear member. Certain members are continuously connected for common rotation. Specifically, an interconnecting member continuously interconnects for common rotation the carrier member of the first planetary gear set, the sun gear member of the second planetary gear set and the ring gear member of the third planetary gear set. Additionally, the sun gear member of the first planetary gear set is grounded to the transmission casing via a radially-extending structural member.

Multi-speed transmission

The invention relates to a multi-stage transmission provided with an input shaft (3), which is connected to a shiftable front-mounted planet gear set (10), with an output shaft (4), which is connected to a shiftable main planet gear set (20), and with a number of shifting elements (A to F) whose selective closing enables the shifting of at least six forward speeds without range shift. An output element of the front-mounted planet gear set (10) can be connected to a first input element of the main planet gear set (20) via a first shifting element (A) and can be connected to a second input element of the main planet gear set (20) via a second shifting element (B). The input shaft (3) can be connected to a third input element of the main planet gear set (20) via a fifth shifting element (E). Preferably, a sun gear (11) of the front-mounted planet gear set (10) can be fixed via a sixth shifting element (F) mounted on the side of the front-mounted planet gear set (10) facing away from the main planet gear set (20). The front-mounted planet gear set (10) is provided in the form of a Plus gearing having inner and outer planet gears (12, 13) whose webs (15, 16) are interconnected.

Said sun gear of the planetary gear set (P1) can be coupled to a housing (G) by means of the shaft (3) via a brake (03) and can be connected to the drive shaft (1) via the coupling (13) and the ring gear of the planetary gear set (P2) can be coupled to a housing (G) by means of the shaft (5) via the brake (05). Said sun gear of the planetary gear set (P4) is coupled to a housing (G) as a non-rotatable shaft (7). The shaft (6) is coupled to the connecting bar of the planetary gear set (P3) and can be connected to the drive shaft (1) via the coupling (16). The shaft (9) is connected to the ring gear of the planetary gear set (P4) and can be connected to the shaft (4) via the coupling (49). The drive shaft (2) is connected to the ring gear of the planetary gear set (P3) and to the connecting bar of the planetary gear set (P4).

Multi-stage gearbox

A multi step transmission, of a planetary design, which has an external housing and includes a transmission input shaft and a transmission output shaft. First, second, third and fourth planetary gear sets are each accommodated within the transmission housing along with third, fourth, fifth, sixth, seventh and eighth shafts, and at least six shift elements. The at least six shift elements comprises first and second brakes and first, second, third and fourth clutches, whose selected engagement produces different transmission ratios between the drive shaft and the output shaft such that nine separate forward gears and one reverse gear can be achieved. For each of the forward and reverse gears, only three of the six shift elements are engaged.

Drive housing is for the automatic transmission of a vehicle in which the cover (16) is divided across a transverse plane with an intermediate plate (23) directed towards the interior of the housing and a centring plate (22) next to the torque converter (3). The intermediatge and/or centring plates have groove-like recesses (26 and 30) in their surfaces which when brought together form enclosed suction, pressure and control channels (27,28,31) for the working fluid. ADVANTAGE - Method of creating a system of fluid channels which avoids high prodn. costs.
