Shift module

Shift module (1) for a shift lever of an automatic gear drive, comprising:

• a. a linearly displaceably supported slider (10, 200), which is engageable with the shift lever and which can be displaced linearly within a stationary guiding slot from a rest position to a displaced position, the slider being constrained by the guiding slot to move linearly in two opposite switching directions by means of the shift lever;
• b. a measuring device (20, 92, 94), which interacts with the slider (10, 200), for detecting the shift positions of slider (10, 200);
• and
• c. at least one resetting element (30, 230, 232) that is displaceably supported substantially perpendicularly to the movement direction of the slider (10, 200), the resetting element being in direct contact with the slider and applying a resetting force to the slider (10, 200) and being biased against a guiding face, the guiding face comprising two opposing partial faces (13, 14, 212, 214) each of the two opposing partial faces being convex in shape continuously over the portion of the guiding face that comes into contact with the resetting element and each of the two opposing partial faces being inclined with respect to the movement direction of the slider (10, 200), the resetting element (30, 230, 232) applying a resetting force having an initially higher magnitude that reaches a maximum then decreases with displacement of the shift lever from the rest position, wherein the resetting element is in direct contact with the slider (10, 200) over the full travel of the slider, the resetting force alone being sufficient to move the slider (10, 200) and the shift lever from the displaced position back to the rest position.

• c. at least one resetting element (230, 232), comprising two spring-biased rollers (230, 232), which are supported in the slider (200) and are displaceable substantially perpendicular to the movement direction of the slider (200), each of the spring-biased rollers (230, 232) being biased against one of two opposing partial faces (212, 214) collectively forming portions of a guiding face, the two opposing partial faces (212, 214) being spaced-apart and convex in shape continuously over the portions of the partial faces (212, 214) that come into contact with the resetting elements, and each of the partial faces being inclined with respect to the movement direction of the slider (200), the resetting element (30, 230, 232) applying a resetting force having an initially higher magnitude that reaches a maximum then decreases with displacement of the shift lever from the rest position, wherein the resetting force acts on the slider (200) over the full travel of the slider in a direction toward the rest position and is alone sufficient to move the slider (200) and the shift lever from the displaced position back to the rest position.
