OSTI ID:6738979
This patent describes a parking lock mechanism for a vehicle having an infinitely variable transmission having a main shaft, a forward gear train, a reverse gear train, coupling means for engaging either of the forward and reverse gear trains with the main shaft, and a selector level for selecting a forward drive range, reverse drive range, and parking lock range. The improvement described here comprises: a parking pawl provided to be engaged with one of locking notches formed on one of rotative members on an output shaft of the transmission; first means for actuating the parking pawl to engage it with one of the locking notches; second means comprising a cam plate rotated by the operation of the selector lever and a cam follower operatively connected to the coupling means for transmitting the operation of the selector lever to the coupling means for selecting the drive ranges and the parking range, the second means being so arranged that the parking range is selected after the selection of the reverse drive range; and the cam plate being so arranged that when the parking range is selected, the cam follower remains at a reverse drive range position to keep the engagement of the reverse gear train.
