摘要： A constant velocity stroking joint includes a housing having an inner cylindrical surface formed with axial guide channels aligned with guide channels of an inner race to provide axial ball tracks for a set of spherical balls. A double offset outer cage has a part-spherical outer diameter surface and a spherical inner diameter surface with centers of curvature axially offset from a center plane of the balls on opposite side thereof to provide constant velocity. An intermediate cage is provided between the inner race and outer cage having a spherical outer diameter surface with a radius of curvature matching that of the mating surface of the outer cage for maintaining constant velocity. The intermediate cage has a cylindrical inner diameter surface mating with a cylindrical outer diameter surface of the inner race, enabling the inner race to stroke axially of the outer cage with low friction, low load rolling action of the balls along the ball tracks while maintaining a constant velocity characteristic for all axial stroke conditions.

摘要： The invention relates to a constant velocity fixed joint and to the introduction of the cage into the outer joint part of a constant velocity fixed joint. The joint comprises an outer joint part, an inner joint part, a ball cage and balls. The outer joint part forms a bell-shaped member comprising a first longitudinal axis, a base, an aperture and circumferentially alternating first and second outer ball tracks. The inner joint part forms a hub comprising a second longitudinal axis and circumferentially alternating first and second inner ball tracks. The first outer and first inner ball tracks, together form first track pairs and the second outer and second inner ball tracks, together, form second track pairs. Each track pair accommodates a torque transmitting ball, with the tangents at the balls in the points of contact with the track pairs forming control angles. The first track pairs form control angles which open towards the aperture in the outer joint part and the second track pairs form control angles which open towards the base of the outer joint part. The outer joint part comprises a substantially internally spherical guiding face which is widened by two recesses which start from the joint aperture and extend into the joint interior.

摘要： A fixed constant velocity joint is provided, which is suitable for an application where a rotational backlash should be avoided. A pressing member is attached to a shaft, and simultaneously a receiving member is attached to a cage. Then, an elastic force of an elastic member elastically bring a pressing part of the pressing member in contact with a receiving part of the receiving member. As a result, an inner race and a cage relatively travel in the axial direction, balls are pushed toward a direction along which wedge-shape ball tracks narrow, and consequently a track clearance in the axial direction decreases.

摘要： A constant velocity joint comprises an inner race, an outer race provided along a periphery of the inner race, a cage sandwiched in between the inner race, the outer race, and balls. A crossing angle between a central axis of the inner race and a central axis of the outer race is bisected, and the balls are disposed within a bisection plane orthogonal to a plane including these two central axes. If a ratio tc/Da is set to rt, there is satisfied a relationship such as: (0.054/rt)nullDanullwnull(0.16/rt)nullDa where Da is the major diameter of each ball, w is the circumference-directional width of each of the column members existing between the pockets adjacent to each other in the circumferential direction with respect to the cage, and tc is the diameter-directional thickness of each of the column members of the cage.

摘要： An assembly comprising a shaft (14) and a female part (6) fixed in terms of rotation on the shaft by rotational-fixing means which cooperate through complementary shapes (16), the female part also being fixed axially on the shaft, and the female part (6; 160; 360) comprising axial first stops (52; 54; 152) which cooperate with associated second stops (44; 46; 144) belonging to the shaft. The first and second stops (44; 46; 52; 54; 144; 152) act in the direction of mounting. The female part (6) further comprises first axial-retention surfaces (60; 160; 360) cooperating with associated second axial-retention surfaces (50; 150; 350) belonging to the shaft. The first and second retention surfaces (50; 60; 150; 160; 350; 360) act in the opposite direction to mounting. The invention applies in particular to ball-type constant-velocity joints for motor vehicles.

摘要： It is made easy to design so that the sliding resistance, when subjected to an impact in the axial direction, is kept within a prescribed value. A constant velocity universal joint is provided, which has track grooves extending in the axial direction on the outer circumference surface of the inner ring, and formed in an intersecting arrangement, and which also embeds balls in these track grooves. In this constant velocity universal joint, the cross-sectional shape of the track groove of the inner ring is constituted by a Gothic arch portion which is a Gothic arch shape up to a location that exceeds a contact point where the groove angular contacts with the ball, and a straight-line portion which is formed continuously with the Gothic arch portion, between the location exceeding the contact point and a shoulder portion of the track groove, and which extends in the direction of the tangent line at the location that exceeds the contact point.
