The steering oil cylinder includes a left steering oil cylinder connected to the left front wheel and a right steering oil cylinder connected to the right front wheel. The left steering oil cylinder and the right steering oil cylinder are in oil connection with a left hydraulic lock and a right hydraulic lock respectively. The left hydraulic lock and the right hydraulic lock are both bidirectional hydraulic locks. The aircraft missile hooking vehicle steering system further comprises a synchronous valve. The left hydraulic lock and the right hydraulic lock are both connected to the synchronous valve which is in oil connection with the steering gear. The steering gear is in oil connection with a pressing oil filter-flow dividing valve mounting assembly which is in oil connection with a plunger pump; and the steering shafts of the left front wheel and the right front wheel are all connected with the steering potentiometer. The aircraft missile hooking vehicle steering system has the advantage of good synchronism of the two front wheels during steering.
Description
Technical field
The present invention relates to airplane ground support equipment technical field, especially relate to a kind of aircraft bomb truck steering swivel system.
Background technology
As everyone knows, aircraft bomb truck need operation below aircraft, so the front-wheel of this bomb truck just needs to extend into below aircraft, the operating control of guided missile also needs to work above front-wheel simultaneously.But the nose wheel steering of current bomb truck is all use same horizontal hydraulic actuating cylinder and connecting rod mechanism to provide steering effort, it turns to drawback very large in airplane ground support equipment, causes synchronism when turning between two front-wheels not good.
Summary of the invention
The object of this invention is to provide a kind of aircraft bomb truck steering swivel system, it has the good feature of synchronism of two front-wheels when turning to.
The technical solution adopted in the present invention is: aircraft bomb truck steering swivel system, comprise deflector and be connected to the steering cylinder of bomb truck front-wheel, and this front-wheel comprises the near front wheel and off front wheel, described steering cylinder comprises the left steering oil cylinder and right steering oil cylinder that are connected to the near front wheel and off front wheel respectively, this left steering oil cylinder and right steering oil cylinder respectively fluid are connected with left hydraulic lock and right hydraulic lock, this left side, right hydraulic lock is bidirectional hydraulic lock, simultaneously, this aircraft bomb truck steering swivel system also includes synchronous valve, this left side, the equal fluid of right hydraulic lock is connected to this synchronous valve, and this synchronous valve fluid is connected to this deflector, this deflector fluid is connected with force feed filter-flow divider valve installation assembly, this force feed filter-flow divider valve installation assembly fluid is connected with plunger pump,
The steering shaft of described left and right front-wheel is all connected with and turns to potential device, this turns to potential device to be connected with control panel;
The described potential device that turns to is connected with instrumentation.
The present invention is compared to the prior art advantageously: when turning to, the synchronism of two front-wheels is better.Aircraft bomb truck steering swivel system of the present invention guarantees the fluid distributed uniform of steering procedure middle left and right steering cylinder by synchronous valve, thus two front-wheel steerings are synchronous.Meanwhile, this bidirectional hydraulic lock avoid the fluid that may occur in steering procedure cause because of unbalance loading synchronous valve out of proportion, turn to nonsynchronous situation.After optimization, this front-wheel steering axle there is corner potential device to detect the angle turned to, thus turning error can directly feed back to above control panel and instrumentation, the angle turned to can be seen more intuitively on the one hand, the angle that another aspect electrical control equipment can regulate and control to turn to, more ensure that the synchronism turned to, synchronization accuracy can be made to reach 1.5%.

In figure: 11, left steering oil cylinder, 12, right steering oil cylinder; 21, left hydraulic lock, 22, right hydraulic lock; 30, synchronous valve; 40, deflector; 50, force feed filter-flow divider valve installation assembly; 60, plunger pump; 70, potential device is turned to; 101, the near front wheel, 102, off front wheel.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 4: aircraft bomb truck steering swivel system, comprise deflector 40 and be connected to the steering cylinder of bomb truck front-wheel, and this front-wheel comprises the near front wheel 101 and off front wheel 102.Concretely, this steering cylinder comprises the left steering oil cylinder 11 and right steering oil cylinder 12 that are connected to this near front wheel 101 and off front wheel 102 respectively, this left steering oil cylinder 11 and right steering oil cylinder 12 respectively fluid are connected with left hydraulic lock 21 and right hydraulic lock 22, and this left hydraulic lock 21 and right hydraulic lock 22 are bidirectional hydraulic lock.Wherein, so-called fluid connects, and refers between parts and is communicated with by pipelines such as high pressure fuel pipes, be connected with hydraulic oil in this high pressure fuel pipe, thus realizes the power transmission (lower same) between link by hydraulic oil.Simultaneously, this aircraft bomb truck steering swivel system also includes synchronous valve 30, this left hydraulic lock 21 and right hydraulic lock 22 all fluid are connected to this synchronous valve 30, and this synchronous valve 30 fluid is connected to this deflector 40, and this deflector 40 fluid is connected with force feed filter-flow divider valve installation assembly 50.This force feed filter-flow divider valve installation assembly comprises pressure pipeline filter, monostable flow divider valve.And this force feed filter-flow divider valve installation assembly 50 fluid is connected with plunger pump 60.
Like this, the course of action of this aircraft bomb truck steering swivel system is: plunger pump 60 fuel feeding is to force feed filter-flow divider valve installation assembly 50, then fluid through deflector 40 rotation and be assigned to synchronous valve 30, be more finally applied to left steering oil cylinder 11 and right steering oil cylinder 12 respectively respectively through left hydraulic lock 21 and right hydraulic lock 22.
Further say, the steering shaft of this near front wheel 101 and off front wheel 102 is all connected with and turns to potential device 70, this turns to potential device 70 to be connected with control panel.Further, this turns to potential device 70 to be connected with instrumentation.Like this, after this corner potential device 70 detects the angle turned to, turning error between two front-wheels directly feeds back on control panel and instrumentation, the angle turned to can be seen more intuitively on the one hand, the on the other hand control panel angle that can regulate and control to turn to, makes to turn to synchronism better between this near front wheel 101 and off front wheel 102.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
