A connector arrangement for interconnecting a first component 12 and a second component 14, the connector arrangement having a connector member 16 including a first abutment face 20a shaped to cooperate with a face of the first component 12, the first abutment face 20a being provided with a series of spline teeth formations 18a, the dimensions of the first abutment face 20a being selected relative to the first component 12 such that the spline teeth formations 18a thereof dig into the material thereof, the connector member 16 further having a second abutment face 20b shaped to cooperate with a face of the second component 14, the second abutment face 20b also being provided with a series of spline teeth formations 18b, the dimensions of the second abutment face 20b being selected relative to the second component 14 such that the spline teeth formations 18b thereof dig into the material of the second component 14.

An interference fit connection for a shaft comprises a hub having a conical through opening and a reduction sleeve having a cylindrical through opening for arrangement on the shaft and a conical outer circumference, where the cone angle of the conical outer circumference corresponds to the cone angle of the corresponding conical through opening of the hub. The hub is a two-component part having a first component made of steel and a second component made of fiber-reinforced plastics material. The second component made of fiber-reinforced plastics material is designed as a ring which is arranged on the outer circumference of a sleeve portion of the first component, which sleeve portion surrounds the reduction sleeve, so as to surround this sleeve portion. The fiber-reinforced plastics material has a higher modulus of elasticity than the steel of the first component.

A method for connecting a constant velocity joint having a bell and a shaft to a wheel bearing having an opening, the shaft being oversized relative to the opening, includes applying an adhesive to the shaft and/or the opening, the adhesive in an uncured state being configured to reduce a coefficient of friction between the shaft and the opening, pressing the shaft into the opening to form a press connection between the shaft and the wheel bearing, and curing the adhesive or allowing the adhesive to cure. Also a subassembly formed by the method.

A torque transmission shaft includes a shaft and a clamp. The shaft includes: a male serration in one axial end portion; a slit in the other axial end portion, the slit axially extending and having a closed end on one side and an open end on the other side; a fitting cylinder portion in the other axial end portion; and a female serration provided in of the other axial end portion. The clamp includes: a discontinuous portion arranged at one place in the circumferential direction; a pair of flange portions arranged on both sides of the discontinuous portion; a connecting portion connecting the flange portions; and an insertion hole for fitting cylinder portion. The clamp is fitted onto the fitting cylinder portion to reduce the diameter of the fitting cylinder portion by narrowing the width dimension of the discontinuous portion.

A power transmission shaft includes a metal shaft member, and a resin shaft member connected to the metal shaft member in an axial direction of the power transmission shaft. The resin shaft member is made of fiber reinforced plastic. The metal shaft member and the resin shaft member are joined to each other through a close-contact fitting portion between a male spline, which is formed in an outer surface of the metal shaft member, and a female spline formed by press-fitting the male spline into the resin shaft member. An edge is formed at a radially outer edge portion of a press-fitting-start end surface of the male spline of the metal shaft member.

In one example in accordance with the present disclosure an apparatus for attaching to a shaft using a wedge is described. The apparatus includes a disc having a longitudinal axis. At least a portion of the disc is insertable into a shaft and is expandable against an inside diameter of the shaft. The disc has a recess at the longitudinal axis. A wedge to be inserted into the recess pushes the portion of the disc that is insertable into the shaft against an inside diameter of the shaft.
