摘要:
The invention relates to a shift assembly (50) for a motor vehicle transmission (16), comprising a housing (22) defining a longitudinal axis (24), at least one first and one second shift rod (60, 62) mounted for axial movement in relation to the housing (22) for engaging and releasing respective associated gears (1-3, 2-4), a hydraulic assembly (74) having at least one first and one second hydraulic cylinder (68, 70), wherein the first hydraulic cylinder (68) is configured to axially move the first shift rod (60) in at least one axial direction (76, 78), wherein the second hydraulic cylinder (70) is configured to axially move the second shift rod (62) in at least one axial direction (76, 78), wherein the first and the second hydraulic cylinders (68, 70) are secured on a common hydraulic cylinder carrier (72). In addition, the first and second hydraulic cylinders are connected to the associated shift rods (60, 62) in such a way that the first and second shift rods (60, 62) extend in opposing directions (76, 78) starting from the hydraulic cylinder carrier (72).
