Abstract
In a pressure type differential limiting clutch, a drive plate and a driven plate provided between a clutch drum for transmitting a driving force to a front drive shaft and a clutch hub for transmitting the driving force to a rear drive shaft are pressed by a pressure force of a cone disk spring provided in a pressure plate, and an initial torque by the cone disk spring acts as the differential limiting torque. At a high speed, a weight in limiter device is moved in a radius direction by a centrifugal force through rotation of the rear drive shaft, enters between cam surfaces formed on the pressure plate and the clutch hub, and pushes and broadens. As a result, the pressure plate moves back against energizing force of the cone disk spring, and the initial torque is cancelled.
