Abstract: PROBLEM TO BE SOLVED: To provide a differential gear mechanism capable of detecting a locked or an operating state.
SOLUTION: This differential gear mechanism comprises a gear case 11 rotatably stored in a housing H and a means 37 having a member axially movable between a first position and a second position and limiting the rotation of a side gear 25 relative to the gear case 11. The mechanism also comprises a sensor assembly 95 and a sensor element 97 adjacent to the gear case 11, and the member movable in the axial direction comprises a detected part 89 surrounding the outer peripheral surface of the gear case 11, and disposed between the outer peripheral surface of the gear case 11 and the sensor element 97. When the detected part 89 is moved according to the unlocked state or locked state of the differential gear mechanism, a first or a second output signal is transmitted from the sensor assembly 95 to a vehicle control logic, and the vehicle control logic controls the other portions or functions of the vehicle.

Abstract: An electronically triggered locking differential includes a differential case, at least one pinion gear and a pair of side gears. A clutch pack is disposed between one of the side gears and the differential case and retards relative rotation between the differential case and the side gear. A cam member is disposed adjacent the clutch pack so that the clutch pack engages when the cam member ramps up. An engagement shaft has one end engaged with the cam member and an opposite end extending through the differential case and engaged with a sprocket. A magnetic coil and flux conductor magnetically couple the sprocket to the differential case when the coil is energized. This coupling retards rotation of the engagement shaft and the cam member relative to the gear case, initiating engagement of the clutch pack to lock the differential.

Abstract: A hydraulic bulkhead (10) configured for use with a limited slip differential includes a plenum (18) comprising a passageway for hydraulic fluid and a boss (26). A first seal (28) is located on an outer surface of the boss (26). The outer surface of the boss (26) is a low pressure area relative to the inner surface of the boss (26). The plenum (18) is stationary relative to the limited slip differential. A differential assembly including the inventive hydraulic bulkhead (10) is also disclosed.

Abstract: A hydraulic coupling for use in a vehicle drivetrain to couple a pair of rotary members and includes a coupling mechanism supported in a casing and that is operable to couple the pair of rotary members together. A piston is responsive to pressurized fluid generated by a pump to move between first and second positions, thereby engaging the coupling mechanism. The pump has an outlet located in a direction away from the piston. An internal passage provides fluid communication between the outlet of the pump and an expandable chamber formed adjacent the piston. A control valve controls the flow of pressurized fluid from the pump between the sump and the expandable chamber.

Abstract: Un acoplamiento hidráulico para uso en un tren motriz de vehículo para acoplar un par de miembros giratorios e incluye un mecanismo de acoplamiento soportado en una cubierta que es operable para acoplar al par de miembros giratorios juntos. Un pistón responde a fluido presurizado generado por una bomba para moverse entre primera y segunda posiciones, con ello vinculando al mecanismo de acoplamiento. La bomba tiene una salida localizada en una dirección fuera del pistón. Un pasaje interno proporciona comunicación de fluidos entre la salida de la bomba y una cámara expansible formada adyacente al pistón. Una válvula de control controla el flujo de fluido presurizado a partir de la bomba entre el sumidero y la cámara expansible.
