Abstract

A hydraulic servo steering engine system belongs to the steering engine device of an aircraft. A direct current motor is fixed on a machine core, the direct current motor is connected with a hydraulic pump, a flow channel and an oil cavity are cast inside the machine core, and the oil cavity is interconnected. Four servo valves are mounted on the machine core axially and symmetrically, each servo valve is respectively connected with an oil cylinder, the piston rod of the oil cylinder is hinged with a connecting rod which is hinged with a rudderpost, the rudderpost is connected with an angular displacement sensor which is connected with a controller, and the controller is connected with the servo valves to form a one-to-four hydraulic servo control system. The invention has new principle, highly integrated structure, small volume, light weight, quick response and high reliability, and is applicable to different severe environments.

Description

Technical field: [0001] The utility model relates to a hydraulic servo steering gear system, which belongs to a steering gear device of an aircraft. Background technique: [0002] The steering gear system is an indispensable key component in the aircraft control system. The steering gear is the actuator that controls the flight state of the aircraft, and it plays a decisive role in the maneuverability of the aircraft. It executes the instructions issued by the control system, manipulates the deflection of the rudder to generate torque, stabilizes and controls the aircraft, and makes it fly according to the set route. [0003] With the development of some new aircraft products, higher requirements are put forward for some aircraft steering gear: small size, light weight, fast response, precise control, adaptable to harsh operating environments, good dynamic and static performance, high reliability Wait. In particular, very stringent requirements are put forward for volume ...
