Abstract

The servo steering linkage has a rotating input (18) shaft controlled by the operator with a coaxial output (16). There is a flexible rotation connection between the input and output. There is also hydraulic assistance and control. The connection has a transmission with two arms and a body fixed to the input and output parts. Inside this is an opening (14) in which slide two pistons with a compression spring between them, to press the pistons against two plugs which have their position altered. The pistons have a rod moving with one arm.
