Abstract:
An interlock mechanism for a transmission system having a gear unit with a plurality of selectable gear ratios, a manually operated clutch control member manually movable from an engaged position to a disengaged position, having a pair of shift rails movable to select gear ratios, and having a pair of detent members, each movable into a detent position wherein, it engages a corresponding one of the shift rails and prevents movement thereof, the interlock mechanism comprising:an interlock member, the interlock member being movable from a lock position wherein the interlock member engages both detent members and holds both detent members in their detent positions to a release position wherein the interlock member is disengaged from both detent members; an interlock spring biased to urge the interlock member to the lock position; and a linkage coupling the interlock member to the clutch control member so that movement of the clutch control member fully to its disengaged position causes the interlock member to move to its release position.
