Abstract: A method is directed to controlling a traction control system including a controllable center coupling and a controlled brake system. The method provides for receiving axle speed information, receiving a vehicle speed, determining at least one difference value between the vehicle speed and the axle speed information, and activating the controllable center coupling and the controlled brake system responsive to the difference values. The step of activating the controllable center coupling responsive to at least one of the difference values may include comparing the at least one difference value to at least one associated threshold value, and activating the controllable center coupling based on the comparison. The step of activating the controllable center coupling based on the comparison may include determining an engine torque request value based on the comparison, and engaging an engine with the controllable center coupling based on the engine torque request value.

Abstract: A fuel injector comprising a valve member which is engageable with a valve seating to control fuel delivery from the injector, an actuator arrangement and an amplifier arrangement for transmitting movement of the actuator arrangement to the valve member. The amplifier arrangement comprises a piston member with which the actuator arrangement is cooperable to apply a retracting force to the piston member, and a control chamber for fluid. The amplifier arrangement preferably comprises a mechanical coupling arrangement for coupling movement of the piston member to the valve member upon application of an initial retracting force to the piston member. The amplifier arrangement is arranged such that, upon application of the initial retracting force, the valve member is caused to move with the piston member away from the valve seating, movement of the valve member being decoupled from the piston member following initial movement of the valve member away from the valve seating so as to provide variable amplification of movement of the actuator arrangement to the valve member.

Abstract: A method for unlocking a steering system that includes detecting and validating an identity input. After the identity input is validated a vehicle start command is detected and thereafter a steering assist mechanism is enabled. Once the steering assist mechanism is enabled, a force is applied to a steering column utilizing the steering assist mechanism. Following an application of the force by the steering assist mechanism, the steering system is unlocked by an unlocking mechanism. After unlocking of the steering system, a vehicle may then be started. The application of the force to the steering column may be alternating application of a clockwise and counterclockwise torque or may be a directional torque applied to the steering column based on a measured steering characteristic.

Abstract: The present invention provides a method and control scheme to operate a motor-driven actuator. This includes determining actuator force on an external device, determining a command force, and monitoring actuator position. A determination is made whether to operate in a force-control mode or a position-control mode. Both the force-control mode and the position-control mode employ a common feedback control method (e.g. PI or PID). The system operates the actuator in the force-control mode, using actuator force as feedback to the control scheme when the controller determines that the force sensor is operating in its linear range. When the force sensor is operating outside or near the limits of its linear range, the control scheme determines a pseudo-force, comprising estimated force based upon measured position. The pseudo-force is input to the common feedback control method to control the actuator.

Abstract: A constant velocity joint includes outer and inner races with mating part-spherical surfaces in which a single functional set of ball grooves are formed bearing a single torque-transmitting ball which is urged under an applied torque load toward one axial end of the joint. A retainer is carried by one of the two races or the shafts to which they are connected and acts on the ball to maintain the ball within the grooves during all angles of the joint.

Abstract: An apparatus and method are provided for adjusting the axial distance between the front and rear walls of a vacuum booster, from outside of the booster, after the booster has been assembled. The booster includes a housing having a front housing and a rear housing joined together and defining a longitudinal axis of the booster. The front housing defines a front wall of the housing and an inner surface of the front wall. The rear housing defines a rear wall of the housing and includes a captive nut having threads adapted for threaded engagement with a threaded end of a tie rod. The front and rear walls are spaced an axial distance from one another along the longitudinal axis. A tie rod extends axially through the housing and has a first end engaging the rear wall of the housing and a second end engaging the front wall of the housing. The first end of the tie rod has threads for engaging the threads of the captive nut in the rear wall of the housing. The second end of the tie rod has an axially facing surface thereof for applying an axially directed force against the inner surface front wall of the housing. The axial distance of the housing between the front and rear walls of the housing is adjusted by turning the tie rod, to thread the first end of the tie rod farther in or out of the captive nut. The captive nut may include a tube extending axially therefrom along a part of the tie rod into the interior of the housing, through one or more separate fluid chambers within the booster, to provide a sealed passageway precluding leakage between the fluid chambers along the tie rod

Abstract: A tripot joint (10) includes a tripot housing (12) having three guide channels (24) receiving three corresponding trunnions (20) of a tripot spider (16). A ball assembly (28) is mounted on each of the trunnions (20) and received in the guide channels (24). The ball assembly includes an inner ball (30), and outer ball (40), and a complement of roller elements (52). The inner balls (30) are slidable axially on the roller elements (52) relative to the outer balls (40). Each ball assembly (28) includes at least one yieldable retainer (58) mounted on the outer ball (40) and projecting into the axial sliding path of the inner ball (30) in at least partial overlapping relation to the inner ball (30). The yieldable retainers secure the inner and outer balls (30, 40) against axial separation prior to joining the ball assemblies (28) with the trunnions (20) and guide channels (24). During operation of the joint (10), the yieldable retainers (58) are displaced out of the axial sliding path through normal axial forces exerted by the inner ball against the retainers (58), allowing for full functional axial sliding movement of the inner balls (30) relative to the outer balls (40) during transmission of torque through an angle of the joint (10).
