摘要： A hub-integrated-type constant-velocity joint device in which one hub housing (40) functions as both an outer race of a constant velocity joint and a wheel hub combining a disc (2) of a wheel and a knuckle (3). In this configuration, a boot sealing portion (110) integrally formed at a boot (50) is inserted in a gap (35) between an inner race (32) and an outer race (33) of a bearing (30), thereby functioning as an inner seal closing up the gap between the inner race (32) and the outer race (33).

摘要： A driving wheel bearing apparatus has an inner ring 5 secured to a wheel hub 1 by a caulked portion 13. An outer joint member 14 of a constant velocity universal joint 3 has a shoulder portion 19 and a cylindrical shaft portion. Face splines 19a and 13a are formed at the end faces of the shoulder portion 19 and the caulked portion 13. Face splines 19a and 13a are supported with pressure by a fastening bolt 21 that abuts the outer side end face of the wheel hub 1 and is threadedly connected to an internal thread 20a of the shaft portion 20. Compressive remaining stress is placed on the surfaces of the face splines 19a and 13a as a result of surface modification, by shot peening. The surface hardness is set at 300 Hv or more.

摘要： A device for elastic interconnection of two rotatable shafts consisting of a first sleeve intended to be connected to a first shaft end. The sleeve has a radial flange and a cylindrical, annular portion connected to the periphery of the flange. A second sleeve is intended to be connected to a second shaft end and to be surrounded by said cylindrical portion. A number of elastically deformable spherical elements are arranged in opposing recesses in said second sleeve and cylindrical portion and distributed around a shaft end. The recesses in the cylindrical portion are arranged in the end surfaces of plugs and provided with external threads. The plugs by being turned are displaceable in threaded bores provided radially in the wall of the cylindrical part. The outer end surfaces of the plugs are provided with diametrical grooves and the cylindrical portion is provided with a diametrical groove. The diametrical grooves and the peripheral grooves define an annular groove. A locking ring is disposed in the annular groove to lock all the plugs in a desired position.
