CONTROLE DE MUDANCA SENSIVEL A ROTACAO

摘要

Disclosed is a shift control (60) for operating an automatic engine transmission from a remote location preferably by means of a flexible cable (12) that is adapted to prevent an operator from shifting from and through a neutral position (N) while the engine speed is above a predetermined value. Shift control (60) has a control arm (2) that when moved in opposite directions in a plane along a frame (3) to various gear positions is operable to rotate a plate (26) having an arcuate extension (28) having an opening (32) therethrough through which a pin (34) is able to extend and prevent movement of arm (2) when the engine speed is above the predetermined value and which in a retracted condition preferably maintains a sliding contacting relationship with extension (28). Pin (3) is preferably an extension of the core of an electrical actuator such as solenoid (18) secured to frame (3) which is powered through an electrical conductor (22) from a suitable power source (V) and which is actuated and deactuated according to whether the engine speed sensed by speed sensing means (44) is above or below a predetermined speed value by means of comparator means (46).
