An object of the present invention is to provide a wheel bearing apparatus which can prevent generation of cracks during the face spline forming process. The present invention provides a wheel bearing apparatus in which a double row rolling bearing and a constant velocity universal joint are detachably united, the double row rolling bearing comprising an outer member formed on its outer circumference with a body mounting flange to be mounted on a body of a vehicle and its inner circumference with double row outer raceway surfaces; an inner member including a hub wheel and at least one inner ring, the hub wheel being integrally formed with a wheel mounting flange on its one end and an axially extending cylindrical portion and the inner ring being press-fitted onto the cylindrical portion of the hub wheel, the inner member being formed with double row inner raceway surfaces to be oppositely arranged to the double row outer raceway surfaces; and double row rolling elements rollably disposed between the double row outer raceway surfaces of the outer member and the double row inner raceway surfaces of the inner member; the inner ring being axially immovably secured by a caulked portion formed by plastically deforming the end of the cylindrical portion radially outward; the constant velocity universal joint having an outer joint member including a cup-shaped mouth portion, a shoulder portion forming a bottom of the mouth portion, and a shaft portion axially extending from the shoulder portion and formed on its inner circumference with female thread all of which are integrally formed; and end faces of the shoulder portion of the outer joint member and the caulked portion being formed with face splines respectively to join the double row rolling bearing and the constant velocity universal joint in a torque transmittable manner characterized in that the face spline of the caulked portion has a portion in which a tooth height of the tooth space of a portion radially outer than the pitch circle diameter is set lower than that of other portions.

An outer joint member includes a cutout portion that is formed at least at each corner portion on an opening side of a cup section, which is defined between a radially inner opening end portion of each of track grooves and a radially inner spherical surface portion formed between the track grooves. The cutout portion is configured to prevent a cage from interfering with the outer joint member when the cage is incorporated into the outer joint member. The cutout portion and the track grooves of the outer joint member are finished by cold-forging ironing using a single ironing punch.

To provide a shaft drive type vehicle in which a location of spline coupling can be lubricated favorably while ensuring a configuration advantageous for reducing the weight of a transmission structure between a drive shaft (29) and a gear meshing with a bevel gear (35) located on a most downstream side. A final gear box (31) is provided which accommodates a pinion gear (33) and a bevel gear (35) in a rotatable manner and contains an oil. A recess (29H) in which to dispose an upstream end of a pinion gear shaft portion (33A) is provided at a downstream end of a drive shaft (29). The recess (29H) and the upstream end of the pinion gear shaft portion (33A) are splined coupled with each other so that the drive shaft (29) and the pinion gear (33) can be rotated as one body and relatively moved in an axial direction. A space (S1) permitting relative movement between the drive shaft (29) and the pinion gear (33) in the axial direction is provided between the pinion gear (33) and the recess (29H). In addition, the pinion gear (33) is provided with a hollow portion (33X) which pierces the pinion gear (33) in the axial direction and conducts the oil to the space portion (S1).

A constant velocity joint boot assembly has a boot can connected to an outer race of the joint. The boot can receives a portion of a boot. The thickness of the boot may be changed in different areas to result in different boot performances. A sleeve is connected to the inner race. A portion of the sleeve may have a complementary shape to a portion of the boot, also to result in different boot performance. A clamp may be located over a portion of the boot to secure it to the sleeve.

The invention relates to a method for producing a connecting element for transmitting rotational movements, wherein the connecting element has an outer articulation part or flange and an attachment pin. The problem of providing a method for producing a connecting element with an outer articulation part or flange and an attachment pin with which weight-optimised connecting elements can easily be produced is solved by deforming a round or tubular blank to form the connecting element by flow turning.

A constant velocity joint (20) includes an outer member (26) defining a plurality of outer member ball tracks (32, 34) and an inner member (38) defining a plurality of inner member ball tracks (42, 44). The outer member ball tracks (32, 34) and the inner member ball tracks (42, 44) cooperate to define a plurality of uniform funnels (50) having a uniform width (W) along a longitudinal axis (L), and a plurality of diverging funnels (52) having a diverging width (W) along the longitudinal axis (L). A drive ball (48) is disposed within each of the uniform funnels (50) and the diverging funnels (52). A cage (56) is disposed between the outer member (26) and the inner member (38), and defines a plurality of windows (58) with one of the drive balls (48) disposed within each of the windows (58). The diverging funnels (52) urge the drive balls (48) along the longitudinal axis (L) to pre-load the cage (56), while the uniform funnels (50) do not urge the drive balls (48) along the longitudinal axis (L), thereby reducing the amount of heat generated between the cage (56) and the drive balls (48).

The present invention provides an articulated shaft (10) for an amphibian driveline, the articulated shaft (10) comprising at least three shaft portions (20, 50, 80) and at least three points of articulation (30, 60, 70), wherein the articulated shaft (10) is movable between a protracted position for use of the amphibian on land and a retracted position for use of the amphibian on water. The present invention also provides an amphibian comprising the articulated shaft, and a powertrain comprising the articulated shaft.
