摘要： A vehicle electric drive apparatus is provided with a single hydraulic pump and left-side and right-side drive units. The left-side drive unit includes a left-side electric motor and a left-side transmission mechanism. The right-side drive unit includes a right-side electric motor and a right-side transmission mechanism. One of rotary shafts of the left-side transmission mechanism and one of rotary shafts of the right-side transmission mechanism constitute a pair of pump-drive rotary shafts. The single hydraulic pump is connected to the pair of pump-drive rotary shafts through respective one-way clutches, and is to be driven by one of the pump-drive rotary shafts that is rotated at a speed higher than the other of the pump-drive rotary shafts, so as to output a hydraulic pressure.

摘要： A transmission for a walk-behind wheeled vehicle, the transmission being of the type including at least one casing (2) housing a driver member (3), equipped with rotary drive motor means (4), a rotary driven member (5), two wheel drive shafts (6A, 6B) in alignment, two clutch mechanisms (8) each of which is disposed between the driven member (5) and a wheel drive shaft (6A; 6B), each clutch mechanism (8) being activated by the driven member (5) being driven in rotation forwards, and deactivatable by the wheel drive shaft (6A; 6B) with which it co-operates being driven in rotation forwards, when the speed of rotation of the wheel drive shaft (6A, 6B) is greater than the speed of rotation of the driven member (5). The rotary drive motor means (4) for driving the driver member (3) in rotation are motor means that can be controlled to rotate in two directions of rotation, and each clutch mechanism (8) is of the type that is deactivatable merely by the driven member (5) being driven in rotation in the backwards direction.

摘要： A bi-directional overrunning clutch includes a housing and a pair of hubs substantially coaxially aligned within the housing. A pair of roll cages position a plurality of rollers between each hub and an inner cam surface of the housing. The rollers are positioned to wedge between the hub and the inner cam surface when one of the hub and the housing is rotated with respect to the other. End caps are attached to the housing adjacent to the hubs. A friction disk mechanism includes a friction plate rotating in combination with each the roll cage and a spring compressed between the end cap and the roll cage for biasing the friction member into frictional contact with the hub. An intermittent coupler is located between each roll cage and configured to engage the roll cages so as to permit indexing of one roll cage relative to the other.

摘要： A pump includes a cam member and an armature plate received on an input shaft rotatably supported with a differential housing of a clutch. The pump also includes a cylinder rod slidingly received in a chamber of a master cylinder to pressurize a hydraulic fluid. The cam member includes a ring and a back plate. The ring has an outer, preferably symmetrical, surface with a variable radius defining a ramped portion for outwardly driving the cylinder rod when the cam member is rotated either forward or backward with respect to the differential housing. A coil generates an electromagnetic field when activated drawing the cam member towards the armature plate such that contact forces causes the cam member to rotate with the armature plate. A roller disc is rotatably supported at one end of the cylinder rod for rolling contact between the cylinder rod and the cam surface of the cam member ring.

摘要： A bi-directional overrunning clutch comprising an input gear, a pair of hubs, and a roller assembly is provided. Each hub is engaged to an end of one of a pair of shaft segments of a primary drive axle. The roller assembly is disposed within the input gear and about at least a portion of each hub. The roller assembly includes spring pins, extending from the roller assembly, with ball locks adapted to engage detents on the surface of each hub, so as to form spring pin engagements between the roller assembly and the hubs. In operation, rotation of the input gear causes rotation of the roller assembly. Thereafter, rotation of the roller assembly causes rotation of the hubs via the spring pin engagements. The spring pins, however, are generally adapted to disengage the spring pin engagements when one of the hubs rotates faster than the other hub.

摘要： A hydraulic pump of a driving force distribution apparatus for right and left axles includes a pump shaft, a swash plate supported tiltably, swash plate tilting and holding mechanism unit for tilting and holding the swash plate to one side or to the other side depending on the direction of rotation of the pump shaft, and a hydraulic oil supply mechanism unit having a cylinder block. The cylinder block holds pistons which reciprocate inside cylinder holes while making contact with a tilt surface of the swash plate at their extremities. When the pump shaft rotates in a forward or reverse direction, the pistons reciprocate to supply hydraulic oil sucked from a tank to a suction port of an operation control valve. Thus, the driving force distribution apparatus can apply relative rotating forces to right and left axles even during backward running, with no increase in the size of the apparatus.
