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.
Claims9
Shifting device (1) of a 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 (3b, 3c, 3d), the transmission component is movable by at least one of longitudinal shifting or pivoting about the longitudinal centerline (2a) into at least one end position on the speed change gearbox, and moves against the limit stop (3b, 3c, 3d) in the at least one end position, the device (1) including at least one damping component (8), having at least one ramp-shaped profile (9a, 9b), and at least one roller component (12) preloaded by spring action against the ramp-shaped profile (9a, 9b), the ramp-shaped profile (9a, 9b) is defined at least along a line, on which the roller element (12) travels upon movement of the transmission component toward the limit stop (3a, 3c, 3d), by a contour line (16, 19) proceeding in a rising mode in a direction of rolling.
