It is connected between two yaw drive links 22 and castellated plates 1703 by oscillating bearing 12.
The operating principle of the present apparatus is:
1st, yaw is corrected:When aircraft occurs to during left drift, preceding right-hand tread plate 14 of pedaling drives the first pedal connector 6, passes through
Yaw drive link 22 drive castellated plates 1703 rotate counterclockwise, due to castellated plates 1703 with yaw drive gear 19 engage, thus
Yaw drive gear 19 is driven to rotate clockwise, since yaw drive gear 19 and yaw potentiometer 18 are coaxially disposed, so driving
Dynamic yaw 18 mandrel of potentiometer is rotated clockwise.At this time yaw potentiometer 18 to computer export an electric signal, then by
Left drift state is corrected in analog machine display after computer disposal.Since left and right pedal is symmetrically associated with together by yawing drive link 22
On one yaw boat drive gear 19, left-hand tread plate 13 is to driver side to recession at this time;When aircraft yaws to the right, then otherwise grasp
Make;
2nd, brake:When making ground taxi after aircraft landing, aircraft to be made to come to a complete stop as early as possible it is necessary to implementing brake to it.With
Tiptoe crawl left-hand tread plate 13, right-hand tread plate 14, pedal do revolution action around pedal revolution axostylus axostyle 23, then drive connected to it
Foot pedal lever 24 does rotary motion simultaneously, in the same direction, while by the second pedal connector 3 strut gear 2 is driven to do revolution and transported
Dynamic, so as to which 4 mandrel of driving brake potentiometer rotates, the potentiometer 4 that brakes at this time exports an electric signal, computer disposal to computer
Analog machine shows braking state afterwards.When the external force of two feet cancels, under strut 9 acts in braking back, braking state is released;
In addition, the angle of left and right foot rudder revolution is controlled, can also be played a role when aircraft floor is turned.
Major-minor drives two sets of foot rudders and is connected by brake connecting rod mechanism 16 with yaw linkage 17 by connecting rod (not shown),
Ensure that two sets of corresponding mechanisms are synchronous.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention god.
