A New Linear Electric Loading System

Abstract

The invention discloses a novel linear electric loading system. The novel linear electric loading system comprises a base plate, base plate bosses, bumper block installing tables, bumper blocks, rubber blocks, guide rails, a slide platform, a connecting block, a magnetic railing ruler, drag chain installing angle iron, a force sensor, drag chains, a linear motor, a threaded connecting rod, a linear steering engine, a supporting plate and fixing screws. According to the novel linear electric loading system, aluminum alloy platforms are adopted in the linear motor, the guide rails and the like, and therefore dynamic performance of the system can be improved beneficially. Compared with a traditional loading structure that a servo motor is installed with a ball screw, the novel linear electric loading system has the advantages that the slide platform is adopted, a loading motor and the steering engine are connected through threaded rods, and the shortcomings that the traditional loading structure is long in reversed time and poor in dynamic performance are effectively overcome. Compared with a traditional connecting method using lug rings, the method of connecting the loading motor and the electric steering engine through the threaded rods avoids connecting gaps and improves loading accuracy. When the loading system breaks down, the phenomenon of rotation blocking of the steering engine can be prevented, the steering engine can not be damaged, and the effect of safety protection is achieved.

Description

technical field [0001] The invention relates to a novel linear electric loading system, which belongs to the technical field of control devices, in particular to a loading table of the electric loading system of a linear steering gear. Background technique [0002] The electric steering gear is a classic actuator in the aerospace field, which is of great significance to the normal flight and maneuver control of the aircraft, and is an important flight control servo component. In order to verify the design of the electric steering gear and ensure the quality of the product before leaving the factory, it is necessary to carry out the load test of the electric steering gear. As a new type of power-by-wire actuator, the linear steering gear has broad application prospects. It can be used not only in the flight control system, but also in other occasions that require actuation on the aircraft. [0003] In order to ensure the quality of the research and development of the linear ...
