Abstract
A friction disc transmission including a conventional drive disc rotatable about a vertical axis and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The driven friction disc is rotatably supported between a fixed frame member and a floating plate member. The floating plate member is lifted or lowered by a bellcrank having a pin that is movable within a slot in the floating plate member. A clutch pedal is connected to the bellcrank for pivoting the bellcrank thereby raising and lowering the floating plate member and driven disc. The bellcrank pin is biased by a spring which is connected to the bellcrank to apply a downward normal force on the floating plate member and driven disc. Guide pins are provided on the floating plate member which are engageable with guide brackets to limit the vertical movement of the floating plate member. The friction disc transmission is placed into a forward or reverse drive condition by partially releasing the clutch pedal to permit initial engagement and slippage between the discs. When the clutch pedal is completely released, the bellcrank spring rotates the bellcrank for biasing the bellcrank pin against the lower edge of the floating plate slot thereby providing an additional normal force between the driven and drive discs.
