Four-wheel steering system for automotive vehicles.

摘要

A four-wheel steering system for an automotive vehicle in which a cable linkage (34, 35) is adapted to operatively interconnect front and rear wheel steering mechanisms (A, B). The cable linkage is provided with a displacement transmitting mechanism (50, 60, 70) which includes an input element (61) operatively connected to a front lateral bar (11) in the front wheel steering mechanism through the cable linkage, an output element (72) operatively connected to the rear wheel steering mechanism, and a spring element (63, 73) disposed between the input and output elements to transmit displacement of the input element (61) to the output element (72) without any deflection in a condition where the output element is freely movable and to absorb displacement of the input element in a condition where the output element is restrained by an excessive load applied thereto from the rear wheel steeing mechanism.
