Technical field
The present invention relates to aero-engine machine control techniques field, specifically, relate to a kind of Clutch device for link type engine throttle control system.
Background technology
The engine oil-valve operation system of current domestic tandem two-seater aircraft generally adopts rigid connecting rod and soft cable wire two kinds, but the engine oil-valve operation system of these two kinds of forms does not also have the arrangement of clutch for realizing mechanical linkage and disconnection between forward and backward cabin.Only with rigid connecting rod engine maneuvering system, the mechanical linkage between forward and backward cabin is described below.
Fig. 1 shows typical rigid connecting rod engine accelerator operating system in prior art, primarily of front deck throttle platform 11, rear deck throttle platform 12, transition bearing 13,14,15, the composition such as pull bar 16,17,18,19,20, wherein engine fuel regulator-end linked by pull bar 20.This accelerator operating system is for controlling engine behavior, pilot guidance front deck throttle platform 11 or rear deck throttle platform 12, engine fuel regulating control is controlled with certain proportion transmission campaign by pull bar 16,17,18,19,20, thus change engine speed, to realize the various mode of operation of driving engine, meet aircraft thrust requirements under various flight conditions.Therefore, in the engine oil-valve operation system of current domestic tandem two-seater aircraft, forward and backward cabin throttle platform 11,12 is in mechanical linkage state all the time.
Soft cable type maneuvering system is also the interlock of cabin, front and back, is not repeated herein.
Because forward and backward cabin throttle platform is in mechanical linkage state all the time, when meeting special feelings, rear deck can not obtain the independent preceence of engine oil-valve operation, reduces flight safety to a certain extent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality need, a kind of Clutch device for link type engine throttle control system is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of Clutch device for link type engine throttle control system, comprise support, support is provided with the rotating shaft of a horizontal direction, rotating shaft is set with rear deck throttle platform pull bar rocking arm, front deck throttle platform pull bar rocking arm, described front deck throttle platform pull bar rocking arm is arranged at the outside of rear deck throttle platform pull bar rocking arm, rotating shaft is also provided with two on-of bolt dishes in front deck throttle platform pull bar rocking arm both sides, on-of bolt dish is provided with together with the rear deck throttle platform pull bar rocking arm of both sides is applied in front deck throttle platform pull bar rocking arm by latch respectively, described on-of bolt dish by external force by latch insert or extract, rear deck throttle platform pull bar rocking arm is made to link with front deck throttle platform pull bar rocking arm or be separated, described rear deck throttle platform pull bar rocking arm is connected with engine fuel regulating control pull bar.
The outside of described on-of bolt dish is provided with Compress Spring and is held out against by on-of bolt dish, and described on-of bolt dish is connected with manipulation cable wire, and described manipulation cable wire is pulled by clutch bar handle.
Beneficial effect of the present invention is:
1. can realize mechanical linkage and the disconnection of forward and backward cabin throttle platform smoothly, in particular cases can obtain engine throttle behaviour
Vertical independent preceence, improves flight safety greatly;
2. the present invention is applied to the engine oil-valve operation system of aircraft, and this type aircraft is in China Aviation Testing & Research Inst.
Verified by O&M between the assay period of carrying out, product can realize predetermined function, and maintainability is good.
