Description
Technical Field
The invention belongs to the field of flight control systems of aircrafts, and relates to a side lever device with a load carrying mechanism for linkage of a primary driver and a secondary driver.
Background
The manual operating mechanism in the airplane cockpit has the modes of a central disk type, a central rod type, a side rod and the like. In the cabin of the dual-piloted aircraft, the primary and secondary pilots change the pilot or operate the steering mechanism together in an emergency, and at the moment, the pilots need to quickly sense the magnitude of the force and displacement that the opposite side has applied. The use of a master-slave linkage steering mechanism is therefore the most straightforward and reliable way.
At present, the linkage of the master-slave driving hand operating mechanism is realized by a hard pull rod, a soft steel cable and electric coupling linkage. In addition, patent CN105329438 proposes a displacement type airplane passive side lever linkage mechanism, which adopts two sets of communication devices to realize synchronous linkage of main and auxiliary driving side levers, each set of communication device is composed of 4 connecting pipes, 2 pull rods with cavities and a change-over switch. The main and auxiliary driving side rods are driven by working liquid in the connecting pipes and the pull rod accommodating cavities.
The hard pull rod type linkage mechanism has poor trafficability and is easily influenced by cabin layout; the maintainability of the common steel cable type linkage mechanism is poor; the electric coupling linkage mechanism has high cost and complex control, and a redundancy design is required to obtain higher safety and reliability.
The driver has to feel forcefully when maneuvering the side bar, and the sensory mechanism that applies force to the driver is often referred to as a load mechanism. The common load mechanisms include spring load mechanisms, electro-hydraulic load mechanisms, gas-liquid load mechanisms, electric load mechanisms and the like. No matter the electro-hydraulic load mechanism, the gas-liquid load mechanism or the pure electric load mechanism, the size is large, the control is complex and the cost is high. Conventional spring-loaded mechanisms, however, have a fixed force displacement curve and cannot be adjusted to the speed or personal feel of the driver.
