摘要： The present invention is directed to a spring energized cage centering device for a bi-directional overrunning clutch. The clutch includes an inner race, an outer race, and a cage disposed between them. A biasing member is disposed between a cavity formed in the outer periphery of the inner race and a pocket formed in the inner periphery of the cage which permits rotational movement between the inner race and the cage, but rotationally biases the cage with respect to the inner race toward a neutral position. In one preferred embodiment, the cavity extends through the centerpoint of the inner race to form two openings in the inner race, the biasing member extending through the cavity and radially outwardly from the openings to engage the cage at two different circumferential locations.

摘要： A clutch assembly having driving and driven members with concentric cylindrical surfaces and which are independently rotatable about a common axis. A plurality of recesses are formed in the cylindrical surface of the driving member. The recesses include ramp surfaces which extend to the cylindrical surface. Roller elements are positioned in each of the recesses and a retainer, which is also independently rotatable about the axis, circumferentially interconnects the roller elements together. The retainer causes the rollers to move substantially in unison with one another and a biasing member individually biases each roller element into its respective recesses. During relative acceleration of the driving member relative to the driven member, the roller elements move along and up the ramp surfaces to a position where they become wedged between the driving and driven members. When wedged, torque can be transferred through the clutch assembly.

摘要： An automatic output shaft locking mechanism for electric tools, and particularly a locking mechanism in which the output shaft is driven by electric power and will automatically lock in position when it is turned by an external force, including a retaining end with three equi-angular projections at one end of the output shaft in the tool, and a rotary disk having three equi-angular notches at an outer side. The outer portion of the rotary disk is fitted with a securing ring, and its three notches receive lock rollers respectively. When the retaining end turns, the three projections will push the lock rollers to engage the securing ring so that the output shaft is locked in position.

摘要： A free-wheeling coupling sensitive to the direction of rotation for a motor vehicle comprises a first ring which constitutes a driving element in a towing mode of the motor vehicle, a second ring which constitutes a driven element in the towing mode, clamping elements which act between the first and second rings to transfer torque in both directions of torque flow, a cage in which the clamping elements are disposed, a fixed friction ring, and a friction element actively connecting the cage to the fixed friction ring. The friction element comprises a plurality of friction segments disposed between the cage and the fixed friction ring, the friction segments being slaved to rotate in the circumferential direction with the cage and being lifted away from the fixed friction ring by centrifugal force when they are caused to rotate at a rotational speed which is greater than a predetermined rotational speed. The free-wheeling coupling further comprises a catch interacting between the first ring and the cage under the control of frictional force or an additional frictional element to inhibit over-rotation of the cage with respect to the first ring, thereby preventing "breakthrough" of the clamping elements when the direction of torque flow changes abruptly.

摘要： A rotation transmitting device has an input shaft coupled to the transmission of the engine of a four-wheel drive vehicle and an output shaft coupled to the rear wheel differential. The input and output shafts are mounted rotatably and concentrically relative to each other. An outer ring is rotatably mounted around the input shaft and a cage is rotatably mounted between the opposed surfaces of the input shaft and the outer rink and formed with a plurality of pockets. Engaging elements are mounted in the pockets and adapted to engage the opposed surfaces when the cage and the input shaft rotate relative to each other. Resilient members are mounted in the pockets to keep the engaging elements out of engagement with the opposed surfaces. The cage and the output shaft are coupled to the input shaft with a gap left therebetween in the direction of rotation so as to be rotatable to,ether. The input and output shafts are kept in a neutral position of the above gap by a retaining member. The outer ring is provided with a connecting portion through which the outer ring is connected with a drive shaft coupled to the front wheel differential.

摘要： A vehicle transmission of the type having a main shaft and a parallel counter shaft with a plurality of selectable gear trains therebetween. The axis of the engine crankshaft is disposed perpendicular to intermediate portions of the main shaft and the counter shaft, with the low speed gear trains and high speed gear trains positioned on opposite lateral sides of the crankshaft. This results not only in a reduced size of the transmission in the axial direction of the crankshaft but also in a reduced lateral size of the transmission, as compared with a transmission in which the crankshaft is connected in series to the transmission main shaft. A synchro mechanism is mounted on the counter shaft and a shift drum for operating the synchro mechanism is positioned parallel to the counter shaft. This insures a space for disposition of the synchro mechanism between gears of the relatively large diameter gears on the counter shaft and ensures a smooth shifting operation, without an increase in the lateral size of the transmission due to the shift drum.

摘要： A clutch having an outer ring, an inner shaft mounted in the outer member, a cage interposed between the outer ring and the inner shaft and cam members movably mounted in pockets formed in the cage. A torque-setting elastic member is provided between the cage and one of the outer ring and the inner shaft so that while the torque on the elastic member is smaller than a preset value, they will rotate in unison with some clearance left therebetween in the direction of rotation. When the torque on the elastic member gets larger than the preset value, the elastic member deforms to allow the cage to turn relative to the member engaged therewith. Now, the cam elements are pushed by the cage into engagement with both cam surfaces formed on the inner periphery of the outer member and the other periphery of the inner member, thus bringing the two members into engagement. This input shaft is rotatably mounted in the outer ring by means of two bearings so as to extend through the outer ring.

摘要： A power transfer mechanism incorporated in a multiple path drive system comprises a transfer case disposed between a source of input torque and a pair of drive axles. Torque is transferred directly to the fixed axle and, when required, is transferred automatically to the steering axle through a double-acting overrunning clutch. A friction clutch provides a preset constant friction drive through a separate path in parallel with the overrunning clutch for independent torque transfer from the steering axle to the fixed axle.
