Embodiment Construction

[0028] exist figure 1 As a possible field of use of the actuating mechanism proposed according to the invention for actuating at least one shifting mechanism or shifting element, a cross-sectional view of a multi-speed dual-clutch transmission in the form of an intermediate shaft is shown by way of example.

[0029]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 the two concentrically arranged transmission input shafts w_K1 , w_K2 . 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. A number of idler gears are arranged on each countershaft w_v1 , w_v2 , which mesh with fixed gears...

Abstract

An actuating apparatus for actuating at least one shift apparatus of a transmission for shifting from at least one gear wheel on a hollow shaft (2), having at least one actuator module (1) which can be disposed partially in the hollow shaft (2), is proposed, said module having at least one actuator (4, 5) for internal actuation, which can be operationally linked to at least one coupling element (10, 11, 11') of the shift apparatus, which projects radially into the internal diameter of the hollow shaft (2), wherein the housing (3) of said actuator module (1) has at least one axial mounting guide as a free path for said coupling element (10, 11, 11') upon axial insertion of said actuator module (1) into said hollow shaft (2). Furthermore, a method for the mounting and dismounting of an actuator module (1) having at least one actuator (4, 5) of an actuating apparatus for the internal actuation of at least one shift apparatus on a hollow shaft (2) is proposed, wherein said actuator module (1) is inserted axially using at least one rotational movement along at least one mounting guide into said hollow shaft (3).

Description

technical field [0001] The invention relates to an actuating mechanism of the type defined in the preamble of claim 1 for actuating at least one shift mechanism of a transmission. Furthermore, the invention relates to a method of the type defined in the preamble of claim 12 for assembling and disassembling an actuating mechanism. Background technique [0002] It is known from vehicle technology to actuate a shifting mechanism or a shifting element from radially outside, for example in countershaft transmissions by means of a shift fork or a shift rocker. Transmissions are known, for example, from DE 43 25 964 and DE 103 02 502 A1, in which the shift mechanism or shift element each has an axially displaceable sliding sleeve. Each sliding sleeve is controlled hydraulically. For this purpose, corresponding cooling oil supply channels are arranged in the shaft on which the gearwheels to be shifted are located. [0003] A transmission is known from DE 102 96 584 A1 in which th...
