Abstract: A gearshift clutch in a manual transmission for selection of at least one gearwheel, said gearshift clutch comprising at least one clutch element that is rotatable about an axis of rotation of the gearshift clutch, which clutch element, for transmitting torques about the axis of rotation, meshes at least temporarily and at least partially through at least one first tooth profile made of a metallic material with at least one second tooth profile made of a metallic material within the gearshift clutch, one of said first and second meshing tooth profiles being temporarily displaceable parallel to the axis of rotation in the other of said first and second meshing tooth profiles, so that friction occurs between said first and second meshing tooth profiles, wherein at least the first tooth profile comprises a sliding coating on a surface of the metallic material for reducing friction.

Abstract: In an adjustable-length shaft (1) for transmitting torques comprising a circular inner shaft component (2) that is mounted coaxially through a linear ball bearing for sliding telescopically in axial direction in a hollow outer shaft component (3), the inner shaft component (29 is mounted by two spaced-apart pre-stressed linear ball bearings (4) that are arranged on opposite end sections (6) of the inner shaft component (2) and are received in a reception bore (19) of the outer shaft component (3), a transmission of torque being achieved by a positive engagement of the inner and the outer shaft components (2, 3).
