TWIN OUTBOARD MOTOR HYDRAULIC STEERING SYSTEM

摘要

A hydraulic steering assembly applies a force to a tiller arms of twin marine, o utboard propulsion units and rotates the propulsion units about a steering axis between a center position and hard over positions to each side of the center position. Each propu lsion unit is supported for arcuate movement about a tilt axis which is generally perpendicula r to the steering axis. There is a hydraulic steering apparatus mounted on a first of the propulsion units which includes a hydraulic cylinder pivotally connected to a member which is pivotally mounted on the tiller arm of the first propulsion unit. A tie-bar is pivotally c onnected to the steering apparatus and pivotally connected to the tiller arm of a second said pr opulsion unit. For example, the tie-bar may be pivotally connected to the steering apparatus by a ball joint connected to the steering apparatus by a bracket which moves with the member.
