Rotational shift control for a vehicle transmission

摘要

A rotational shift control for a vehicle transmission includes a control shaft adapted for being operably coupled to the transmission, an interlock member moveable supported adjacent the control shaft and a clutch pedal operably coupled to the interlock member. The control shaft includes a non-cylindrical outer circumferential surface and is rotatable about an axis between a neutral position and a geared position. The interlock member is moveable in a direction along the axis and includes a locking surface opposite the non-cylindrical outer circumferential surface. The interlock member moves between a first engaged position in which the locking surface engages the control shaft to prevent rotation of the shaft and a second disengaged position in which the locking surface disengages the control shaft to enable rotation of the shaft between the neutral position and the geared position. The interlock member is preferably configured to be moved into the engaged position only when the control shaft is in the neutral position. Depressment of the clutch pedal moves the interlock member from the first engaged position to the second disengaged position.
