Rotation rod for automobile servo steering device has input shaft with non-circular cross-section for press-fit coupling with primary shaft of servo steering device

摘要

The rotation rod (6) has an input shaft (5), directly or indirectly coupled to the steering column for receiving the operating torque, a spring section and an output shaft, the input shaft having a non-circular cross-section, for allowing a press-fit coupling with a primary shaft (1) having a corresponding blind bore (4) at its end. An Independent claim for a method for coupling a primary shaft of a servo steering device to a rotation rod is also included.
