Problems solved by technology

These factors all affect the manipulation
A large fit gap will lead to unstable work, and a too small gap will generate a lot of friction, and it is easy to cause the mechanism to get stuck, causing flight safety issues

Abstract

The present invention relates to the technical field of mechanical manipulation, in particular to an aircraft hydraulic-mechanical load mechanism, and aims to solve the technical problem of overcoming the defect in the prior art that the mechanism is stuck due to speed changes and causes flight safety, mainly through the following technical solutions What is achieved: an aircraft hydraulic-mechanical load mechanism, comprising: a casing, a transmission structure and a spring structure are arranged in the casing, and hydraulic oil is also arranged in the casing; a transmission structure, the transmission structure includes a main transmission device and a driven device, the driven device is provided with an oil inlet and an oil outlet; a spring structure, the spring structure is fixedly connected with the transmission structure, and the load mechanism through the cooperation between the transmission structures, the rocker arm- The transmission of the cam-roller-throttle slide valve can form a pressure feedback, thereby changing the control force with the change of the flight speed. The structure is simple, which solves the problem of mechanism sticking and causing flight safety, and effectively improves the flight quality.

Description

Technical field [0001] The present invention relates to the field of mechanical manipulation, and more particularly to a aircraft hydraulic mechanical load mechanism. Background technique [0002] Aircraft technology is a highly comprehensive modern science and technology that has played a huge role in my country's national defense, agriculture, transportation and scientific research. Hydraulic machinery is an apparatus and tool that works through fluid energy. In such devices, hydraulic oil is transmitted to an actuator in the device by hydraulic pump. The hydraulic pump is driven by an engine or an electric motor. Hydraulic oil is controlled by manipulating various hydraulic control valves to achieve the desired pressure or flow. Each hydraulic element is connected by a hydraulic conduit. [0003] The traditional hydraulic mechanism is a spring tip mechanism, and the sensational force provided does not change with flight parameters (H, V, M, QC). To meet the rod requirements at...
