Abstract: A power take-off (PTO) is used to selectively run a secondary device. The PTO includes a clutch assembly having first and second clutch members that are selectively engaged with each other to drive the secondary device. The first clutch member is associated with a driving input and rotates at an input speed. An accumulator is in power communication with the secondary device and is used to provide power to temporarily drive the second clutch member via the secondary device such that a speed of the second clutch member can be synchronized with the input speed for clutch engagement.

Abstract: A king pin is used to couple a knuckle and axle housing together in a steer axle assembly. The king pin is fixed to the axle housing and the knuckle is supported for rotation relative to the king pin. The king pin includes a cylindrical body portion and a suspension mount portion formed about one end of the cylindrical body portion. A shock absorber is mounted to the suspension mount portion of the king pin.

Abstract: An automatic axle engagement system utilizes wheel speed sensors, engine control, and braking control to provide optimal engagement of a front drive axle to provide all wheel drive under poor driving conditions. The system includes a transfer case that is coupled to a power source and which has output shafts for front and rear drive axles. The engine provides torque to the transfer case via an input shaft. Wheel sensors generate wheel speed signals that are transmitted to a controller, which determined whether or not there is wheel slip. The controller initiates a shift to drivingly engage the front drive axle if there is wheel slippage by controlling one or both of the output torque or axle braking forces to bring rotational speeds of the input shaft and the rear axle output shaft within a predetermined speed range.
