摘要： A corrugated portion is formed in one end edge portion of the metallic shaft main body (2), and a triangular corrugated portion (11) is formed in an end edge portion of the shaft auxiliary body (3) on the metallic shaft main body side. The metallic shaft main body (2) and the shaft auxiliary body (3) are integrated by being linearly arranged by way of meshing that brings a side of the triangular corrugated portion (9) on the main body side and a side of the triangular corrugated portion (11) on the auxiliary body side into contact with each other. A fiber orientation angle (¸) of the fiber reinforced plastic of the shaft auxiliary body (3) is set so as to be in the same direction as a direction of stress generated in a hypotenuse of each triangular portion under a torque load state.

摘要： An object of the present invention is to enhance assemblability of a wheel bearing device, and stably maintain predetermined torque transmissibility over a long period of time. A shaft portion (12) of a joint outer ring (5) where projections (35) extending in an axial direction are provided is press-fitted into a hole portion (22) of a hub wheel (1) to thereby form recesses (36) by the projections 35 in an inner diameter surface (37) of a shaft fitting hole 22a of the hub wheel (1), by which a recess-projection fitting structure M is constructed, where an entire area of fitting sites of the projections (35) and the recesses (36) are brought into close contact. Moreover, a bolt member (50) is fastened in a bolt hole (13) provided in the shaft portion (12) of the joint outer ring (5) after the construction of the recess-projection fitting structure (M), which restricts separation between the hub wheel (1) and the joint outer ring (5). As the bolt member (50), if an outer diameter of a seating surface thereof (50a1) is d1 and a shaft diameter is d2, a bolt member satisfying a relational expression of 2.3 ‰¤ (d1 /d2) 2 ‰¤ 4.9 is used.

摘要： Provided is a small-sized, lightweight, low-cost, and highly reliable bearing device for a driving wheel which needs no tapered spline, and eliminates a circumferential backlash in spline fitting portions to thereby prevent unusual noise. The bearing device for a driving wheel comprises an outer race (5) having an inner periphery in which double-row outer raceway surfaces (13, 14) are formed; a hub wheel (1) and an inner race (2) having outer peripheries in which double-row inner raceway surfaces (7, 8) opposed to the outer raceway surfaces (13, 14) are formed; and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2). A shaft hole (28) of the hub wheel (1) is formed into a cylindrical shape, and a male spline (26) is formed on an outer periphery of a stem section (27) of the outer joint member (15) so that the stem section (27) of the outer joint member (15) is press-fit into the shaft hole (28) of the hub wheel (1). With this, recesses caused to closely fit on the male spline (26) with interference are formed in the shaft hole (28) of the hub wheel (1), whereby the hub wheel (1) and the outer joint member (15) are separably coupled to each other.

摘要： A bearing device for a wheel, in which circumferential play is minimized and in which a hub ring and an outer joint member of a constant velocity universal joint can be connected with excellent workability. Axially extending projections (35) are formed on either one of the outer diameter surface of a shaft (12) of the outer joint member and the inner diameter surface (37) of a hole (11) of the hub ring (1), and the projections (35) are axially press fitted into the other. Recesses (36) fitted in an intimate contact manner onto the projections (35) are formed in the other. Thus, a recess/projection fitting structure (M) is formed. In the structure (M), the entire fitting/contact portions (38) of the projections (35) and the recesses (36) are in intimate contact with each other. Further, a shaft come-out prevention structure (M1) is provided between the shaft (12) of the outer joint member and the inner diameter surface of the hub ring (1).

摘要： Provided is a power transmission shaft (12), including: a male spline (19) formed in an outer periphery thereof; and a diameter increasing portion (23) formed on a part of a tooth bottom (19b) of the male spline (19), which is located on an opposite side to an axial end of the power transmission shaft (12), by gradually increasing an outer diameter dimension of the tooth bottom (19b). The tooth bottom (19b) of the male spline (19) has a substantially constant circumferential width (c) extending up to an axial region of the diameter increasing portion (23). The diameter increasing portion (23) includes a chamfered portion (25) formed in the axial region of the diameter increasing portion (23), the chamfered portion (25) connecting the tooth bottom (19b) and a tooth flank (19a) of the male spline (19) to each other to reduce a tooth groove width (d). The tooth bottom (19b), the tooth flank (19a), and the chamfered portion (25) each have a press-formed surface. The power transmission shaft (12) satisfies a relationship of C>D, where C represents an axial dimension between a diameter increase start position (P1)and a tooth groove width reduction start position (P2) of the male spline (19), and D represents an axial dimension between the tooth groove width reduction start position (P2) and a diameter increase finish position (P3) of the male spline (19).
