Abstract: A method of controlling torque transfer from a torque input source to an outlet source in which an electronically controllable magnetorheological fluid-based torque limiting device is coupled to either a differential pinion gear, a side gear, both the differential pinion gear and side gear, or both side gears of a differential assembly. By introducing current through electronically controllable magnetorheological fluid-based torque-limiting device during a turning or spin-out condition, and thereby increasing the viscosity of the magnetorheological fluid within the torque limiting device, the amount of torque that is transferred to the output source through the differential assembly can be controlled.

Abstract: A differential system includes a case, a pair of pinion gears, a pair of side gears and an electrically operable coupling including a magnetically responsive fluid. The coupling selectively drivingly interconnects one of the side gears and the case. In one instance, the present invention includes a rotor having a plurality of outwardly extending blades positioned in communication with a magneto-rheological fluid. An electromagnet is selectively actuated to change the viscosity of the magneto-rheological fluid. In this manner, the differential may function as an “open” differential, a “locked” differential or a differential accommodating a limited-slip condition.

Abstract: A hydraulic device to limit slip can be used in the vehicle's main differential and the vehicle's inter-axle differential. The device includes a cylinder body connected to an input shaft, pistons disposed within radial cylinder bores in the cylinder body, and a cam ring connected to the output shaft, and disposed adjacent the pistons. The cylinder body is generally ring-shaped and has at least one pair of cylinder bores connected by an orifice spaced radially around the cylinder body interior bore. One of the radial cylinder bores in the pair is filled with hydraulic fluid. One piston protrudes from its corresponding radial cylinder bore. The cam ring is also generally ring-shaped having one lobe around its outer circumference per radial cylinder bore pair. As the cylinder body rotates along with the input shaft, the pistons interact with the cam ring lobes. The lobe forces the protruding piston into its corresponding radial cylinder bore. The hydraulic fluid is forced through the orifice and into the other radial cylinder bore in the pair and forces the other piston in the pair to protrude from its radial cylinder bore an to contact the cam ring. The interaction between the cam ring and the pistons creates a drag force that causes the cam ring to rotate with the cylinder bore.
