A disconnecting axle includes a housing assembly including a first end cap coupled to a first side of a housing member to define a clutch cavity, and a second end cap coupled to a second side of the housing member to define a differential cavity. The housing member can define a central bore, a sump, and a plurality of passages. The central bore extends axially between the clutch and differential cavities. The sump can be spaced apart from the clutch and differential cavities, and the central bore. A clutch passage couples the clutch cavity to the sump. A differential passage couples the differential cavity to the sump. A first output member of the differential extends axially within the central bore. A piston is configured to compress friction plates to selectively transmit torque. A pump can pump fluid from the sump to the cylinder to move the piston.

A composite flywheel (13), comprising a primary flywheel (15) integral with an input shaft (31) and a secondary flywheel (17) coaxial with the primary flywheel (15). The secondary flywheel (17) and the primary flywheel (15) are constrained so that they can rotate freely with respect to each other. A coupling device (61) is further provided, adapted selectively to: transmit power from the input shaft (31) to the secondary flywheel (17); and disengage the secondary flywheel (17) from the input shaft (31).

A one-way clutch apparatus of torque input-switching type in which torque capacity can be secured without increasing an axial dimension. The one-way clutch apparatus of drive input-switching type, includes a plurality of first torque transmitting members interposed between a shaft 3 and an intermediate ring 7 at circumferential predetermined intervals, and provided for transmitting torque between the shaft 3 and the intermediate ring 7, and a plurality of second torque transmitting members interposed between the intermediate ring 7 and an outer ring 5 at circumferential predetermined intervals, and provided for transmitting torque between the intermediate ring 7 and the outer ring 5, in which either the torque input into the shaft 3 or the torque input into the outer ring 5 is transmitted to the intermediate ring 7, in which the first torque transmitting member is a sprag 23 and the second torque transmitting member is a roller 29.

Disclosed is an air compressor in which a driving shaft and a crankshaft tube that surrounds the driving shaft are axially coupled, a clutch is installed between the driving shaft and a rear end of the crankshaft tube, and an air cylinder including a steam cylinder, a piston spaced apart at a certain distance from the steam cylinder, and an interval former installed between the steam cylinder and the piston is installed in a crankcase that forms a pump chamber, to prevent frictional ring plates that rub steel ring plates of the clutch together from being worn by a determined thickness or more by the interval former and simultaneously to cut off supplying of compressed air to the inlet of the air cylinder by the interval former in such a way that a connection state between the driving shaft and the crankshaft tube is continuously maintained.

This invention refers to a hydraulic bearing clutch which is placed between the engine and the gear box, being suitable for any type of gear box. The hydraulic bearing clutch, according to this invention includes: a metal disc (1) coupled with an engine flywheel (2), a PTO shaft (3) attached to the metal disc (1) and tied in with a rotor (8) of the hydraulic pump (4) and a pressure chamber (7) mounted on the PTO shaft (3). Inside the hydraulic pump (4) there is a ball drum (9) tied in with the rotor (8) of the pump and in gear, through blocking, with the stator (15) of the pump. The stator is tied in with the primary shaft (6) on which are mounted a low pressure chamber (33) and a high pressure chamber (28). The high pressure chamber (28) is connected to a pressure regulator (38) and, through a solenoid valve (37), to the pressure chamber (7) on the PTO shaft (3). The pump rotor (8) has provided some radial rectangular seats (29) into which slide some metal blades (14), connected with an axial groove (11) and a radial groove (10) which correspond to the pressure chamber (7) on the PTO shaft (3). The axial groove (11) corresponds to a circular groove (17) and to the radial grooves (18) on the drum (9) and some balls (20) press on a circular groove (21) with bulges on the stator (15). The stator (15) is provided with admission ports (23), corresponding to the cross grooves (25) and the radial grooves (26), but also to the axial grooves (27) on the primary shaft (6). These grooves also make the connection with the high pressure chamber (28) and the low pressure chamber (33).
