| 发明名称 | Journal cross of a universal joint | ||
| 摘要 | A journal cross of a universal joint includes a base body from which four journals extend outwardly, each journal of the four journals having a cylindrical section and an outer diameter and a length in an axial direction of the journal. The four journals are formed as tubular structures, an inner diameter of each of the tubular structures is at least 67% of the outer diameter of each of the tubular structures, the journal cross is formed as a one-piece component from which the four journals as well as the transitions between the four journals are also formed, and the four journals merge in a common cavity which is formed in an interior of the journal cross. | ||

| 主权项 | 1. A journal cross of a universal joint comprising: a base body from which four journals extend outwardly, each journal of the four journals having a cylindrical section and an outer diameter and a length in an axial direction of the journal, wherein the four journals are formed as tubular structures, wherein an inner diameter of each of the tubular structures is at least 67% of the outer diameter of each of the tubular structures, wherein the outer diameter and the inner diameter for each journal are centered about a common axis, wherein the journal cross is formed as a one-piece component from which the four journals as well as the transitions between the four journals are also formed, wherein the four journals merge in a common cavity which is formed in an interior of the journal cross, and wherein the interior of at least one of the tubular structures is filled with a metal foam. | ||
