CONTROL UNIT BRAKING DEVICE

摘要

CONTROL UNIT BRAKING DEVICE A single lever control unit for sequentially operating a transmission and throttle and, selectively, for operating the throttle independently of the transmission. A throttle shaft assembly disengages from a throttle gear by pulling out the shaft while in the neutral position. A double key on the throttle shaft disengages from a keyway in the throttle gear and a springloaded pin engages a cavity in the throttle gear to lock both shift and throttle gears in the neutral position. Throttle only may then be applied. When the hand lever is returned to the neutral position, the throttle shaft automatically engages the throttle gear and the locking pin automatically disengages by means of spring loading. The locking pin prevents pulling out the shaft in other than the neutral position. A spring provides axial loading between the throttle arm connected to the shaft and a friction plate mounted on the shaft. This loading creates a frictional drag which prevents throttle creep. Additional throttle braking is achieved during throttling by means of an adjustable screw forcing a friction pad against a specially profiled side of the throttle gear. An adjustable flange accommodates a neutral interlock lever. The flange can be angularly oriented in any desired position.
