摘要： A power transmission mechanism for a vehicle includes a clutch assembly which includes a two-way clutch and an electromagnetic clutch. The two-way clutch includes three rows of rollers retained by a retainer and disposed between a clutch inner member, which is actually a stem of a constant-velocity joint mounted on the outboard end of a drive axle, and a clutch outer member, which is actually a hub ring of a hub bearing supporting a vehicle wheel. Simply by energizing and deenergizing the electromagnet of the electromagnetic clutch, the two-way clutch can be engaged and disengaged. Since the rollers are arranged in three rows, it is possible to increase the contact area between the rollers and the clutch inner and outer members and thus the maximum torque that can be transmitted through the rollers without the need to increase the number of rollers in each row or their length or diameter.

摘要： A cross groove constant velocity universal joint of which weight of the outer ring is reduced. The cross groove constant velocity universal joint includes a disc-shaped outer ring having ball tracks in the inner circumferential surface, an inner ring having ball tracks in the outer circumferential surface, balls set between the pairs of the outer ring ball tracks and the inner ring ball tracks, and a cage that retains all the balls within the same plane. Bolt holes are arranged between adjacent ball tracks of the outer ring, and recesses are formed such as to reduce the outside diameter of the outer ring except for both axial ends, at least between adjacent bolt holes.

摘要： A shaft coupling includes plates fitted on ends of input and output shafts, respectively. A plurality of guide grooves are formed in the opposed surfaces of the plates, respectively, so that each of the grooves extends perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves of the plates at a portion where the pair of grooves cross each other. When the steel balls are pushed by the driving plate, they push the driven plate while rolling in the guide grooves, with their movements restricted by a retainer in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates, there are only the steel balls and the retainer.

摘要： An object is to provide a shaft coupling which is short in axial dimension, which can transmit large power between shafts even if the offset amount of the shafts is large, and which is less expensive and can be assembled easily. The shaft coupling includes plates 1 and 2 fitted on ends of input and output shafts A and B, respectively. A plurality of guide grooves 5 and 6 are formed in the opposed surfaces of the plates 1 and 2, respectively, so that each of the grooves 5 and 6 extend perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves 5 and 6 of the plates 1 and 2 at a portion where the pair of grooves 5 and 6 cross each other. When the steel balls are pushed by the driving plate 1, they push the driven plate 2 while rolling in the guide grooves 5 and 6, with their movements restricted by a retainer 4 in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates 1 and 2, there are only the steel balls 3 and the retainer 4. Thus, the shaft coupling is sufficiently short in axial length, can be manufactured at a low cost, and can be assembled easily.
