Connecting rod engine throttle control system clutch device

Abstract

The invention relates to a clutch device for a link type engine throttle control system. The device comprises a support, a horizontal spindle is arranged on the support, and rear compartment throttle table link rockers and front compartment throttle table link rockers are sleeved on the spindle. The front compartment throttle table link rockers are arranged on the outsides of the rear compartment throttle table link rockers, two clutch bolt discs are arranged on the two sides of the front compartment throttle table link rockers on the spindle, and bolts are arranged on the clutch bolt discs to thread the rear compartment throttle table link rockers and front compartment throttle table link rockers on the two sides together. The bolts are inserted in or pulled out by the clutch bolt discs through external force, so that linkage or separation is achieved between the rear compartment throttle table link rockers and front compartment throttle table link rockers, and the rear compartment throttle table link rockers are connected with an engine fuel regulator link. By means of the clutch device, mechanical linkage and separation of front and rear compartment throttle tables can be achieved smoothly, the alone priority of the engine throttle operation can be obtained in particular cases, and the flying safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of aero-engine mechanical control, in particular to a clutch device of a connecting-rod engine throttle control system. Background technique [0002] At present, the engine throttle control system of domestic tandem two-seater aircraft generally adopts two types: hard connecting rod and soft cable, but these two types of engine throttle control systems have not been used to realize the mechanical linkage and disconnection between the front and rear cabins. open clutch. The mechanical linkage between the front and rear compartments will be described below only with the hard connecting rod engine control system. [0003] figure 1 It shows a typical hard connecting rod engine throttle control system in the prior art, which mainly consists of a front cabin throttle console 11, a rear cabin throttle console 12, transition supports 13, 14, 15, pull rods 16, 17, 18, 19, 20, etc. Composition, wherein the tie rod ...

AI Technical Summary

Problems solved by technology

[0005] Since the throttle consoles of the front and rear cabins are always in a state of mechanical linkage, in case of special circumstances, the rear cabin cannot obtain the sole priority of engine throttle control, which reduces flight safety to a certain extent
