Abstract:
A shifter assembly includes a shift lever, a base, a coupling member having a toothed member and pivotably coupling the shift lever to the base, and a speed sensitive damping arrangement housed in the base. The damping arrangement includes a housing associated with the base and defining an internal cavity, a shaft disposed in the cavity and having an end extending from the housing, and a gear coupled to the shaft end extending from the housing and configured for rotation therewith, where the gear is meshingly engaged with the toothed member of the coupling member such that pivotable movement of the coupling member rotates the gear and the shaft. The gear is configured to rotate faster than the shift lever such that damping to movement of the shift lever provided by the damping arrangement is proportional to a square of a speed of movement of the shift lever.
