Abstract
A shifting device (1) for a speed change gearbox with a transmission component that can be shifted in a longitudinal direction and/or about its longitudinal axis in a pivoting manner, which for transmitting the shifting movements is equipped with a damping component (8), which is constructed from at least one ramp-shaped profile (9a), and at least one roller component (12) which is pre-loaded against ramp-shaped profile (9a) by means of spring action.
Claims6
Shifting device (1) of a manual speed change gearbox, comprising a transmission component that can be shifted longitudinally and/or about a longitudinal centerline in a pivoting fashion to transmit shifting movements, and at least one limit stop (16a, 19a), the transmission component is movable by at least one of longitudinal shifting or pivoting about the longitudinal centerline (17) into at least one end position on the speed change gearbox, and includes the at least one limit stop (16a, 19a) in the at least one end position, the device including at least one damping arrangement (8), having a first ramp-shaped profile (9a) and a second ramp shaped profile (9b), and at least one roller component (12) pre-loaded by spring action against the first and second ramp-shaped profiles (9a, 9b), the first ramp-shaped profile (9a) is restricted in at least a longitudinal direction along a first line on which the roller component (12) rolls upon longitudinal movement of the transmission component toward the first limit stop (16a), through a first contour line (16) extending in a rising mode in the direction in which the roller component (12) moves, and the second ramp-shaped profile (9b) is at least restricted into the pivot direction along a second line on which the roller component (12) rolls upon pivoting movements of the transmission component toward a second limit stop (19a), through a contour line (19) proceeding in a rising mode in a direction in which the roller component (12) rolls during pivoting movements of the transmission component, each of the limit stops of the shifting device is formed at an end portion of each of the ramp-shaped profiles.
