摘要： The present invention offers a power steering device for a four-wheel drive, which includes: a first self-aligning torque estimation unit for estimating a self-aligning torque generated in a current vehicle behavior as a first self-aligning torque; a second self-aligning torque estimation unit for estimating a self-aligning torque that is to influence a subsequent vehicle behavior as a second self-aligning torque; a self-aligning torque change amount calculation unit for calculating a difference of the second self-aligning torque from the first self-aligning torque as a self-aligning torque change amount; and an assisting force correction unit for determining and outputting a corrected value of an assisting force to be generated for a steering operation based on the self-aligning torque change amount. Therefore, even when the self-aligning torque changes as the distribution of the front and rear driving power is variably controlled, a corresponding assisting force is generated, maintaining a natural steering feeling without causing an unpleasant sensation to the driver.

摘要： 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 65 moves back against energizing force of the cone disk spring, and the initial torque is cancelled.
