Embodiment Construction

[0025] exist figure 1 As an example of a possible area of ​​use for the device proposed according to the invention for shifting at least one idler gear on a mating shaft of the transmission, a cross-section of a multi-speed double clutch transmission in countershaft construction is shown in open map.

[0026] The dual clutch transmission includes two clutches, the input ends of which are connected to the drive shaft. Furthermore, a torsional vibration damper is arranged on the drive shaft. The outputs of the two clutches are each connected to one of two transmission input shafts w_K1 , w_K2 arranged concentrically with one another. The first transmission input shaft w_K1 is designed as a solid shaft, and the second transmission input shaft w_K2 is designed as a hollow shaft. Furthermore, two countershafts w_v1 , w_v2 are provided, which are arranged axially parallel to one another. On each countershaft w_v1 , w_v2 are arranged a plurality of idler gears which mesh with fix...

Abstract

The invention relates to a device for switching at least one idler gear (1, 2, 3) on an associated shaft of a transmission, the device comprising at least one shifting device comprising an operating mechanism (4, 5 , 6) and a friction-locked and / or form-fitted shifting mechanism, the shifting mechanism is axially movable through the operating mechanism, and the operating mechanism is at least partially arranged in the shaft, and the shifting mechanism is arranged concentrically with the shaft . According to the invention, an axial extension is provided between the operating mechanism of each shifting device and the shifting mechanism, said axial extension is assigned to the shifting mechanism, and the first shifting device includes a A moving sliding sleeve (7) with said axial extension as shifting mechanism, and said axial extension is formed as at least one protruding receiving area (9, 9'), said protruding receiving area The area is used for fastening at least one drive pin which can be coupled to the actuating mechanism.

Description

technical field [0001] The invention relates to a device for shifting at least one idler gear on an associated shaft of a transmission. Background technique [0002] A device is known from the inventor's as yet unpublished application DE 10 2006 049 274 for actuating a gear designed as an idler gear of a transmission arrangement in the form of a countershaft. The transmission device includes two shifting mechanisms, which can respectively shift two idler gears of the intermediate shaft. The shifting mechanism is arranged in the interior of the countershaft, which is designed as a hollow shaft, and actuates a concentric and axially displaceable sleeve element in order to connect the associated idler gear to the countershaft in a rotationally fixed manner. Since the installation space within the hollow shaft is limited, the arrangement of the shifting mechanism is not arbitrarily possible. Therefore, the idler gears that need to be shifted are also arranged at certain axial ...
