Abstract
A motor throttle assembly for attachment to a vehicle handle bar. The motor throttle assembly includes a cable pull with a pair of opposed outwardly extending guide posts. The cable pull is disposed within a tubular inner sleeve having a pair of longitudinal cutouts designed for receiving the guide posts therethrough. The inner sleeve is rotatably supported within an outer sleeve having a pair of helical cutouts overlaying the longitudinal cutouts and designed for receiving the guide posts. Manually rotating the outer sleeve produces cooperative action of the helical cutouts and longitudinal cutouts to apply equally balanced force to the guide posts and cause the cable pull to traverse and accelerate the motor. Bearings support the traversing movement of the guide posts and the rotational movement of the outer sleeve for a smooth action of the throttle, with minimal play. The motor throttle assembly is configured to fully open the throttle with an approximately one half turn and the throttle assembly has a spring return.
