Abstract: An internal combustion engine relies on a liquid coolant to dissipate heat that is produced by combustion within the engine. A coolant pump, which is driven by the engine itself, circulates the coolant through passageways in the engine. The pump includes a clutch such as a magnetic particle clutch or a magnetorheological clutch, that relies on a magnetic field to control the speed at which the pump operates and the rate that it circulates the coolant, so that a variable speed ratio exists between the speed of the engine and the speed of the pump.

Abstract: A bi-directional clutch permits the unidirectional transfer of torque between inner and outer races in either direction of rotation, depending on how the clutch is set. The outer race has a cylindrical raceway presented inwardly toward the inner race, whereas the inner race has recesses presented outwardly toward the raceway in the outer race. Each recess has ramps which converge and each contains a cylindrical roller. The rollers fit into pockets in a cage, with the fit being quite close so that the circumferential position of the cage relative to the inner race controls the position of the rollers in the recesses of the inner race. The inner race carries actuators which operate against the rollers in two different pockets, one to prevent the rollers from moving up the ramps presented in one circumferential direction and the other to prevent the rollers from moving up the ramps presented in the other circumferential direction.

Abstract: The present invention relates to an active toe control system for an automotive vehicle where the system includes a control arm or link that is axially adjustable to either shorten or lengthen the length of the control arm or link. The control arm includes an electric motor connected between the connecting points of the control arm or link, the electric motor being responsive to an electronic control unit that communicates signals the electric motor to control the rotation of the electric motor and the duration of time the electric motor is operated. The combination of components acts to actively adjust the toe of the wheels of an automotive vehicle.
