<p>A torque absorbing coupling for a hydrostatic steering system which a hydrostatic steering controller responds to operation of a steering wheel to direct flow from a source to a steering motor. The coupling minimizes the possibility of a high reaction torque being felt by the operator who turns the steering wheel more rapidly than the system can deliver flow and pressure to the controller to levels which are sufficient to effect steering as demanded by the operator. The coupling is provided between the steering wheel and the controller's metering unit, and operates to absorb reaction torques over a time intervals and thereby delays transmission of those reaction torques to the operator over that time interval, to provide the system with an additional time interval to increase flow and pressure to the levels demanded.</p> |
