Background technology
Hydraulic booster is an a kind of mechanical hydraulic servo mechanism, is mainly used on the products such as automobile, aircraft, and chaufeur is as long as handle servo-unit with very little power, and the mechanism that servo-unit just can drive big load works, to reach the light purpose of use.
Also can utilize some assisted control devices that flight is better controlled to reduce workload the aviation field aviator.Along with the increase of aerocraft size and the raising of performance, the complexity and the weight of mechanical type flight control system also increase considerably, big limitations the development of aerocraft.In order to overcome these restrictions, the fluid pressure type flight control system has occurred.After the hydraulic flight control system occurred, the size of aerocraft and performance no longer received the restriction of chaufeur strength, and just received economic restriction.The modal structure of hydraulic booster is side valve type hydraulic booster and steering valve hydraulic booster.
At present, what the steering valve hydraulic booster adopted all is hydraulic boosters of single rotary valve, therefore when the rotary valve et out of order, can directly influence the use of hydraulic booster, thereby influence the flight quality of aircraft, brings personal safety hidden danger to the aviator.
Summary of the invention
The purpose of the utility model is to want to provide a kind of new hydraulic booster, and this hydraulic booster is safe, can effectively improve the flight quality of aircraft, ensures aviator's personal life security.
For the technical scheme that above-mentioned purpose adopted that realizes the utility model is: a kind of hydraulic booster, comprise left cavity, input rocking arm, support, extremity piece, be provided with left pressurized strut, piston rod in the left cavity; Being provided with left compound rotary distributor in the pressurized strut of a left side, is bearing fit between piston rod and the left pressurized strut, supports to be installed on left pressurized strut front end; And contact with piston rod, its constructional feature is: between extremity piece and left cavity, increase a right cavity, piston rod extends in the right cavity; The shared piston rod of left and right two cavitys; Be provided with right pressurized strut in the right cavity, be provided with sleeve between right pressurized strut and the piston rod, be provided with right compound rotary distributor in the right pressurized strut; In left and right pressurized strut, all be provided with micro-switch; Micro-switch is connected with left and right compound rotary distributor respectively, between left and right pressurized strut, is provided with to connect to support, and the input rocking arm is hinged on to connect and supports; The input rocking arm links to each other with the compound rotary distributor in the right side through connecting rod mechanism, and extremity piece is installed on the end of right pressurized strut.
Described left and right compound rotary distributor all contains main valve, secondary valve, lining, and secondary valve is positioned at lining, and main valve is positioned at secondary valve.
The most preferred embodiment of the utility model for about the oil filter all is installed in two pressurized struts, to filter servomechanism in-to-in fluid.
Another most preferred embodiment of the utility model is provided with the dust blowing device for the external part at piston rod, can constantly clean piston rod.
The utility model is on the basis of former hydraulic pressure servo-unit, and epitrochoidal chamber changes to two chambeies by a chamber, can work simultaneously and also can work independently in two chambeies, simultaneously, has increased micro-switch as blocking warning, and its principle of work is following:
The operator operates the input rocking arm of hydraulic booster, handles compound rotary distributor through connecting rod mechanism.The kinematic velocity of the mouth of the angle direct control hydraulic booster that compound rotary distributor is opened.Compound rotary distributor contains main valve, secondary valve and lining, and under the normal operation, only main valve is driven, and it rotates secondary valve end and distribution lining relative fixed in secondary valve.The secondary valve end of compound rotary distributor links to each other with micro-switch through the lever that is installed in its end.When main valve blocks, drive secondary valve and rotate, former fixed part (secondary valve end and distributing valve lining) is thrown off, last pushing lever left end, this moment, the lever right-hand member pressed down the shake-up micro-switch, blocked warning and started working.
The utility model becomes the two-chamber hydraulic booster owing to be on hydraulic booster basis, single chamber, to have increased by a chamber, also is about to the hydraulic booster of original single rotary valve; Upgrade to two rotary valve hydraulic boosters, and increase micro-switch as blocking warning, therefore; When the rotary valve et out of order in any cavity wherein, the rotary valve in another cavity still can continue to use, and blocks warning simultaneously and begins to report to the police; Remind the aviator to note; Thereby further improved the flight quality of aircraft, increased safety factor, ensured aviator's personal life security.Especially be installed on the hydraulic booster on the helicopter, in case the loss of losing efficacy will be very serious.The utility model also can be reduced to minimum with economic loss when improving safety factor; When any cavity et out of order wherein; Blocking warning just begins to report to the police; Remind the operator that hydraulic booster breaks down, the timely repaired item of operating personal this moment, thus avoided unnecessary economic loss.
