Embodiment Construction

[0022] figure 1 The shifting module 2 depicted in is provided for shifting operations of a group transmission (not shown), which has a multi-stage main transmission, a two-stage half-gear group located in front of the main transmission, and a rear transmission. It is a two-stage double gear group in the main transmission. For this purpose, three shifting cylinders 6 , 8 , 10 and a selector cylinder 12 are arranged on the inner side of the housing 4 facing the shifting transmission. The shifting cylinders 6 , 8 , 10 can be actuated pneumatically and are arranged parallel to each other. The selector cylinder 12 is likewise designed to be pneumatically actuable and is arranged transversely or perpendicularly to the three shifting cylinders 6 , 8 , 10 .

[0023] arranged in figure 1 The first shift cylinder 6 on the left is assigned to the half-gear group of the sub-group transmission, and has a rotationally symmetrical punch-shaped rod head 16 on its piston rod 14 for coupling...

Abstract

The invention relates to a shifting module for actuating an automated shifting transmission. The shifting module has at least one shifting actuator designed as a shifting cylinder, the piston rod of which, in the assembled state, is in an adjusting connection with a shifting lever of a shifting device located inside the transmission in an axially fixed manner, and shifts the gears. The module has a selector actuator in the form of a selector cylinder, the piston rod of which has a U-shaped receptacle oriented transversely to its longitudinal axis and, in the assembled state, is in an adjustable connection with a selector lever located inside the transmission in a rotationally fixed manner The swing arm is inserted into the receptacle. The pivot arm is assigned to the shifting module and is fastened to the piston rod of the shifting cylinder in a rotationally fixed manner, and the piston rod of the shifting cylinder is axially fixed and rotationally fixed to the shift transmission in the assembled state The selector lever is connected, the selector lever itself is arranged axially fixed and rotatably supported about its longitudinal axis in a selector lever located inside the transmission.

Description

technical field [0001] The invention relates to a shifting module for actuating an automated shifting transmission, the shifting module having at least one shifting actuator designed as a hydraulic or pneumatic shifting cylinder, the piston rod of which is in the In the assembled state, it is in adjustment connection in an axially fixed manner with a selector lever in the form of a hollow shaft of the shifting device located inside the transmission, and the selector module has a selector actuator in the form of a hydraulic or pneumatic selector cylinder. , the piston rod of the selector actuator has a U-shaped receptacle oriented transversely to its longitudinal axis, and, in the assembled state, a pivot arm in an adjusting connection with the selector lever located inside the transmission in a rotationally fixed manner inserted into the receptacle. Background technique [0002] The automatic shifting transmissions of motor vehicles are usually derived from manual shifting ...
