Embodiment Construction

[0025] right now figure 1 and figure 2 An explanation is given in which an exemplary embodiment of a gearshift rocker according to the invention is explained.

[0026] Correspondingly, the shift rocker, which is designated together with the reference numeral 1, is composed of two half parts 2 of the same type and a connecting element 3 which firmly connects the two half parts 2 to one another.

[0027] Each half-part 2 has a curved spatial structure which is formed from a slightly elongated flat material, for example consisting of sheet steel. To this end, several bending operations are required, in which the different profiled sections of the flat material are hemmed by forces acting on the wide forming surfaces 4 and 15 in a direction perpendicular to the longitudinal direction of the flat material.

[0028] The effect of a bending process is thus to curl the first end profiled section 5 relative to the second profiled section 6 in the direction of bending. The further b...

Abstract

Switch rocker (1) of a switching device for a gear change box, especially for motor vehicles, comprises two half parts (2) forming a switch mouth (19) that are rigidly interconnected via a connecting element (3). Independent claims are also included for: (1) Switching device for a gear change box, especially for a motor vehicle, comprising at least one switch rocker; (2) Gear change box, especially for a motor vehicle, comprising at least one switch rocker; (3) Motor vehicle with a gear change box comprising at least one switch rocker; and (4) Production of a switch rocker. Preferred Features: The connecting element is made of a harder material than that of the two half parts.

Description

technical field [0001] The invention belongs to the technical field of transmission systems and relates to a shift rocker, especially for a shift device of a gear-type transmission gearbox of a motor vehicle. Background technique [0002] In geared transmissions with a countershaft, the escape wheel as a floating wheel (Losrad) is rotatably mounted on the main shaft, while the countershaft gear as a fixed wheel is connected in a rotationally fixed manner to the countershaft superior. Here, the gear pairs, each consisting of a countershaft gear and an escape wheel, mesh continuously with each other. The non-positive connection is produced by means of a slide associated with the escape wheel, which is displaceably mounted on the main shaft along its longitudinal center axis in a rotationally fixed manner, which can form-fit with the escape wheel. Mesh. [0003] For gear selection and shifting, a shifting device is provided, which typically includes a shifting shaft operated...
