A resilient Cardan joint for steering columns

摘要

A universal joint yoke in a vehicle steering column is connected to a tubular shaft 12 with the interposition of shock-absorbing material 14 and the shaft and yoke are retained together axially by means of a curved zone 21 of the yoke cooperating with projections 22 of the shaft 12. This eliminates the need for a separate retaining bolt. The cross sections of the end of shaft 12 and the part of the yoke receiving it are non-circular to ensure torque transmission (Fig. 4).
