A cardan joint for steering columns

摘要

A Cardan joint is designed to eliminate the bolt normally used between male and female interfitted tubular elements for preventing axial motion and for coupling the parts so as to facilitate assembly of the shaft under any conditions, i.e. both in the factory and when the shaft is repaired. For preventing axial motion and holding the elements together, the outer surface of the male part and the inner surface of the female part have distorted cross-sectional portions. The male part has projections at one end which have a peripherally indented configuration similar to the female part.
