Abstract

The invention belongs to an automatic flight control technology, particularly relating to an embedded friction clutch which is used in an actuating mechanism of an airborne automatic flight control system and can also be used in other control systems. In recent years, various friction clutches are required to be used in actuating mechanisms (such as a fuel control rod mechanism and an electric steering engine) in airborne automatic flight control systems of new developed airplanes in China. Along with increasing of requirements on reliability, safety and service life of the airplanes, conventional friction clutches cannot meet requirements. In order to solve the problem, the high-stability embedded friction clutch which is wear-resistant, resists high-temperature and low-temperature environments and is long in service life is required. The invention provides the friction clutch which is compact in structure and has high stability and high wear resistance in a transmission process.

Description

technical field [0001] The invention belongs to the flight automatic control technology, and in particular relates to an embedded friction clutch, which is used in the executive mechanism of the airborne flight automatic control system and can also be used in other control systems. Background technique [0002] In recent years, various friction clutches have been used in the actuators (such as throttle actuators, electric steering gear, etc.) of the airborne automatic flight control system of my country's newly developed aircraft. With the improvement of aircraft's requirements for reliability, safety, and service life, conventional friction clutches can no longer meet the requirements. In order to solve this problem, a highly stable embedded friction clutch that is resistant to wear, high and low temperature environments, and long life is required. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention pro...
