发明名称 SHIFT ELEMENT SUB-ASSEMBLY FOR A TRANSMISSION
摘要 A shift element sub-assembly for a transmission having two axially adjacent shift elements ( 2, 3 ) that are located in a transmission housing ( 1 ). The discs of both shift elements ( 2, 3 ) lie axially adjacent in the interior of the disc carrier ( 4 ) and are separated from one another by a central partition ( 40 ) of the disc carrier ( 4 ). Each shift element ( 2, 3 ) has a piston ( 23, 33 ) and a closing pressure chamber ( 24, 34 ), and at least one resetting element ( 27, 37, 39 ) for resetting the piston. Additionally, each shift element ( 2, 3 ) has a secondary piston ( 26, 36 ), which acts on the discs of each shift element ( 2, 3 ) in opposition to a resetting force of the resetting element ( 27, 37, 39 ) of each shift element ( 2, 3 ), via the piston ( 23, 33 ) of each shift element ( 2, 3 ), and at least one resetting element ( 27, 37, 39 ) of the shift element sub-assembly is configured as a drain pressure chamber ( 27, 37 ) that can be hydraulically or pneumatically actuated.
