摘要： The invention relates to a homokinetic sliding joint for longitudinal shafts of motor vehicles, said joint consisting of an outer joint body and an inner joint body (1; 2) on which ball-bearing rails (3; 4) are formed, a cage (5) provided between the joint bodies (1; 2), and balls (7) which are provided in the individual pairs of ball-bearing rails and guided in the cage (5). The ball-bearing rails (3; 4) are arranged in the outer joint body (1) and in the inner joint body (2), in an alternate sequence, rising to the right and rising to the left, forming inclined, spatially arranged ball-bearing rails (3; 4) when the joint bodies (1; 2) are assembled. The individual ball-bearing rails (3; 4) have a helix angle ß 8 and an angle of inclination ß' 9 that are defined in relation to each other by the ratio ß : ß' = 5:3.

摘要： A rolling bearing (20) is provided on an outer peripheral surface of a hub spindle (13) of a hub wheel (10) on which a wheel is mounted. Opposite side face splines (18,62), which, by meshing with each other, couple the hub spindle (13) and an outer ring (60) of a constant velocity joint (50) torque-transmittably, are respectively formed on an end face of the hub spindle (13) and on an end face of the outer ring (60) of the constant velocity joint (50) which is abutted against this end face. A tubular seal member (80) for covering outer peripheries of the opposite side face splines (18,62) is disposed so as to straddle an inner ring (21) of the rolling bearing (20) and the outer ring (60) of the constant velocity joint (50), while maintaining a sealing state.

摘要： A drive wheel support bearing assembly includes a hub axle (10), a constant velocity joint (40) and a bearing unit (20) which are unitized together, and an inner member (29) made up of an outer coupling member (41) of the CVT with the hub axle mounted on an outer periphery of a hollow stem portion (45) of the outer coupling member. Inner peripheral side raceway surfaces (27, 28) are formed on the hub axle and the outer coupling member. Hardened indentations (31) are formed in an inner periphery of the hub axle, and the hub axle and the outer coupling member are plastically coupled integrally with each other by radially outwardly expanding a mounting area, at which the hub axle is mounted on the hollow stem portion, to allow it to bite into the indentations to crimp. Sensors (50) for detecting the displacement or deformation of the outer coupling member and the hub axle are provided in the outer member.

摘要： Automatic installation of a circlip is facilitated even when an axial length (inner race width) of a protrusion of an inner race is reduced. An inner race (6) is installed in a constant velocity universal joint for transmitting torque while allowing angular displacement between itself and an outer race, with a shaft being inserted in a shaft hole (12) formed in an inner bore to be spline-fitted thereto so as to be prevented from coming off by virtue of the circlip. A two-step chamfer (20) having different chamfer angles is provided at a shaft insertion side end portion of the shaft hole (12). The two-step chamfer (20) includes a first chamfer section (21) situated on a shaft hole opening side and a second chamfer section (22) provided on the side opposite to the shaft hole opening so as to be continuous with the first chamfer section (21). The chamfer angle α of the first chamfer section (21) is set larger than the chamfer angle β of the second chamfer section (22).

摘要： The present application is directed to a direct torque flow connector for torque transmission. The DTF connector includes a direct torque flow constant velocity universal joint having an outer race part and an inner race part, and a shaft coupled to the outer race part. The direct torque flow connector has at least one direct torque flow optimized ratio. Further, the inner race part of the direct torque flow connector may be selectively connected to a journal shaft of a drive unit. A direct torque flow connection with optimized ratios in attachment methods is also provided.

摘要： A constant-velocity fixed joint (1) comprises a joint outer part (2) which has ball raceways (4) on its inner circumference, a joint inner part (3) which has ball raceways (5) which are separated by webs (18) on its outer circumference, the ball raceways (4, 5) of the joint outer part (2) and of the joint inner part (3) being arranged opposite one another in pairs, balls (6) which are held in the raceway pairs, and a cage (10) which is arranged between the joint outer part (2) and the joint inner part (3), and windows (11) for holding the balls (6). The joint inner part (3) can be inserted into the cage (10) only when at least one of its webs (18) engages in a window (11) in the cage (10). As a result of certain ratios of the raceway angle ϵ to the web angle Ϝ being maintained, a constant-velocity fixed joint (1) is obtained which has high resistance to fracturing with large bending angles and in which weakening at the functional faces of the joint inner part (3) is avoided. In addition, a large wrap around of the balls (6) at the ends of the raceways is obtained and is advantageous for the load bearing capacity of the raceways (4, 5). Furthermore, it is possible for the joint inner part (3) to pivot easily into the cage (10). Owing to its simple form, said cage (10) can be manufactured conveniently and with a small thickness. The constant-velocity fixed joint (1) is furthermore characterized by a particularly compact design.

摘要： The distance L 15 in the axial direction between the surface on the axially outside end of the spline shaft 28a and the opening edge on the axially inside end of the center hole 15 of the hub 5 when the unit is installed, and more preferable the distance L 16 in the axial direction between this surface on the axially outside end of the spline shaft 28a and the edge on the axially inside end of the spline hole 16, is greater than the distance L 18 that the tripod 21 of the constant-velocity joint 18 on the differential side can move inward in the axial direction when installed in the automobile. Therefore, it is possible to prevent the spline shaft 28 from falling out of the center hole 15 even when the connection member 3 is damaged, and to maintain the spline connection between the spline shaft 28 and the spline hole 16.
