Abstract

A device for increasing a selection force is integrated into a support arrangement of a shift lever. The device is pivotable around a pivot axis and also around a tilt axis aligned transversely to the pivot axis. The selection force upon pivoting movements of the shift lever around the tilt axis is produced by at least one lever that is movable against a spring and a runoff roller placed in operative connection with the lever (24, 38). The device is integrated into a support arrangement for pivotable support of the shift lever by a casing in a housing. The support arrangement supports the shift lever pivotably with respect to the casing around the pivot axis and also supports the shift lever with the casing pivotably with respect to the housing around the tilt axis aligned transversely to the pivot axis.

Dependent claims

Device for increasing a selection force on a shift lever (2, 35) pivotable around a pivot axis (8a, 36) and also around a tilt axis (9a, 34) aligned transversely to the pivot axis (8a 36), the selection force upon pivoting movements of the shift lever (2, 35) around the tilt axis (9a, 34) being produced by at least one lever (24, 38) movable against at least one spring (22, 39) and a runoff roller (23, 40) placed in operative connection with the lever (24, 38), the device is integrated into a support arrangement (1, 29) for pivotable support of the shift lever (2, 35) by a casing (10, 31) in a housing (3);

wherein the support arrangement (1, 29) supports the shift lever (2, 35) pivotably with respect to the casing (10, 31) around the pivot axis (8a, 36) and also supports the shift lever (2, 35) with the casing (10, 31) pivotably with respect to the housing (3) around the tilt axis (9a, 34) aligned transversely to the pivot axis (8a, 36) the device is formed by two ramps (21, 30) fixed to the casing and the runoff roller (23, 40) is rotatably fastened to the lever (24, 38);
wherein the lever (24, 38) is pivotable around a fulcrum (24a, 38a) fixed to the housing (3) and is preloaded via the runoff roller (23, 40) against the ramp (21, 30) by the at least one spring (22, 39) engaging the lever (24, 38) at a point remote from the fulcrum (24a, 38a);
and wherein the ramp (21, 30) pivots with the casing (10, 31) around the tilt axis (9a, 34) upon pivoting movements of the shift lever (2, 35) and the runoff roller (23, 40) supported on the housing (3) rolls on the ramp (21, 30), and two of the levers are provided with a respective one of the levers (24) acting on a respective one of the ramps (21), the levers (24), having the casing (10) with the ramps (21) between them, are preloaded against each other by at least one tension spring (22);
and the tension spring (22) is connected at a free end, remote from the fulcrum (24a), of each one of the levers (24).
