Control linkage for governor and torque sensing hystat

摘要

A control linkage system is disclosed for simultaneous control of an engine throttle or governor and a hydrostatic transmission from a single control pedal, and includes unidirectional linkage means including a pair of triangular-shaped link members mounted for movement about a common axis and connected by links to a unidirectional output member or a throttle control member. The unidirectional linkage means includes a pin mounted on an arm which in turn is mounted on the common axis of the link members and connected by a link and lever arm to move with a rocking foot pedal. A second linkage means including a lost motion link is connected to the pedal and to a swash plate control member of the hydrostatic transmission.
