Cross member, useful in universal joint of propeller shaft of e.g. passenger car, comprises base body, from which four pins extend, where each pin has cylindrical section having diameter and length in axial direction of pin

摘要

The cross member (1) comprises a base body (2), from which four pins (3,4,5,6) extend, where each pin has a cylindrical section (7) having a diameter and a length in an axial direction of the pin. The pins are designed as tubular structure so as to reduce the weight of the cross member, where an inner diameter of the tubular structure is 67% of the outer diameter of the structure. The cross member is designed as a one-piece component that is formed from the pins and the transitions between the pins. The cross member (1) comprises a base body (2), from which four pins (3,4,5,6) extend, where each pin has a cylindrical section (7) having a diameter and a length in an axial direction of the pin. The pins are designed as tubular structure so as to reduce the weight of the cross member, where an inner diameter of the tubular structure is 67% of the outer diameter of the structure. The cross member is designed as a one-piece component that is formed from the pins and the transitions between the pins. The pins merge in a common cavity (9), which is formed inside the cross member. The interior part of the tubular structure and the cavity are filled with metal foam. The member is produced by internal high-pressure forming process.
