Torque Limiter (1) Torque limiter screw (2) Torque cam (3) Limiter spoolThe torque limiter is used in conjunction with torque cam (2) in order to control torque rise on the engine. With the proper setting and the proper torque cam, a torque rise with two slopes can be achieved. In certain agricultural applications, there is a rapid torque rise from rated torque to peak torque. At lower speeds, the rise is more natural.The torque limiter consists of an additional torque limiter screw (1). As the engine speed drops from rated torque to peak torque the rack follows the profile of torque cam (2). At the peak torque, limiter spool (3) contacts torque limiter screw (1). This limits the rack. The torque cam profile continues to change. However, the torque cam profile is no longer used since the rack is stopped by torque limiter screw (1).
