Abstract: It is disclosed an actuator arrangement for a gear box. The actuator arrangement comprises a drive element (3), a cooperation element (4), a transmission element (5), and a shift fork (11). The drive element (3) has a first longitudinal axis. The cooperation element (4) is configured to engage with the drive element (3). The transmission element (5) has a second longitudinal axis that is at an angle to the first longitudinal axis. The transmission element (5) is configured to engage with the cooperation element (4). Operation of the drive element (3) is configured to move the cooperation element (4) along the first longitudinal axis. Movement of the cooperation element (4) is configured to rotate the transmission element (5) about the second longitudinal axis. Rotation of the transmission element (5) is configured to actuate the shift fork (11).

Abstract: A shifting device for a transmission, especially a vehicle transmission, with at least two shift-units (50, 60, 70) is disclosed. The shifting device comprises: at least two shift-rods (51, 61, 71), connected to the at least two shift-units (50, 60, 70) of the transmission respectively, a main shaft (10), configured to support the at least two shift-units (50, 60, 70) in an x-direction, which extends in parallel to a longitudinal direction of the main shaft (10), a select driving block (21) configured to be movable in a y-direction, which is perpendicular to the x-direction, and to transmit a force provided by a select actuator (20) to an adapter (40) in the y-direction, a shift driving block (31) configured to transmit a force provided by a shift actuator (30) to the adapter (40) in the x-direction, wherein the adapter (40) is configured to be moved into at least two predetermined positions in the y-direction, in which the adapter (40) forms a connection with only one of the shift-rods (51, 61, 71) at a time, by which the respective shift-unit (50, 60, 70) can be moved in the x-direction to shift a gear.
