Abstract
The utility model discloses a hard rudder transmission device, which comprises a lower rocking arm and an upper rocking arm. The transmission device is characterized in that the lower rocking arm is positioned on the inclined lower portion of the upper rocking arm, the middle portion of the lower rocking arm is movably sleeved at the upper end of a lower supporting post while the middle portion of the upper rocking arm is movably sleeved at the lower end of an upper supporting post, a rotary shaft is arranged between the lower rocking arm and the upper rocking arm, the lower end of the rotary shaft is connected with the middle portion of the lower rocking arm through a lower universal joint, and the upper end of the rotary shaft is connected with the middle portion of the upper rocking arm via an upper universal joint. By adopting the transmission of the rotary shaft and the universal joints to control motion, the transmission device has the advantages of accurate movement, large load-bearing, convenient examination and repair and strong reliability.
Description
Technical field
The utility model relates to a kind of aircraft, specifically, is a kind of rigid rudder driver of aircraft.
Background technology
Tradition ultralight machine rudder control system is made of the rear arm on pedal, pull bar, lower shake-changing arm and the yaw rudder, the middle part kink of this lower shake-changing arm is in the upper end of lower supporting rod, the two ends of this lower shake-changing arm link to each other with the movable end of pedal through pull bar, like this, step tread drives lower shake-changing arm and rotates, drive the rear arm rotation by the manipulation steel cable that is connected on the lower shake-changing arm again, drive yaw rudder at last and rotate.Because the manipulation steel cable between lower shake-changing arm and the rear arm is soft steel cable, and handles steel cable and also need turn, it is big to cause action to postpone, and understeer is lived, and the load-bearing of steel cable is less, breaks easily.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of manoeuvrable, rigid rudder driver that load-bearing is big.
In order to address the above problem, the technical solution of the utility model is: a kind of rigid rudder driver, comprise lower shake-changing arm and upper rocker arm, lower shake-changing arm is positioned at the oblique below of upper rocker arm, the middle part kink of this lower shake-changing arm is in the upper end of lower supporting rod, the middle part kink of described upper rocker arm is in the lower end of upper supporting column, between described lower shake-changing arm and upper rocker arm, be provided with turning cylinder, the lower end warp of this turning cylinder Hooke's coupling down links to each other with the middle part of described lower shake-changing arm, and the upper end of turning cylinder links to each other with the middle part of described upper rocker arm through last universal joint.
As of the present utility model preferred, be provided with mounting hole at the two ends of described lower shake-changing arm and upper rocker arm, on the arm body, be provided with auxiliary hole.
Now for prior art, the beneficial effects of the utility model are: the utility model adopts turning cylinder, the action of Hooke's coupling transmitting control, and action is accurate, and load-bearing is big, and easy access, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, rigid rudder driver of the present utility model is made of lower shake-changing arm 3, upper rocker arm 10, following Hooke's coupling 4 and turning cylinder 7, lower shake-changing arm 3 is positioned at the inferoanterior of upper rocker arm 10, the middle part kink of this lower shake-changing arm 3 is in the upper end of lower supporting rod 12, be provided with mounting hole at these lower shake-changing arm 3 two ends, the front end of pull bar 2 links to each other with lower shake-changing arm 3 through this mounting hole, and the rear end of pull bar 2 is installed in the movable end of pedal 1.
The middle part kink of upper rocker arm 10 is in the lower end of upper supporting column 9, and the two ends of this upper rocker arm 10 are provided with mounting hole, and the termination of straight line steel cable 11 links to each other with upper rocker arm 10 through this mounting hole.
Turning cylinder 7 is contained between lower shake-changing arm 3 and the upper rocker arm 10, and the lower end of this turning cylinder 7 warp Hooke's coupling 4 down links to each other with the middle part of lower shake-changing arm 3, and the upper end of turning cylinder 7 links to each other with the middle part of upper rocker arm 10 through last universal joint 8.
Like this, step tread 1 drives lower shake-changing arm 3 and rotates, and Hooke's coupling 4, turning cylinder 7, upward universal joint 8 drive upper rocker arm 10 and rotate under passing through again, and then passes through the 11 drive rear arms rotations of straight line steel cable, drives yaw rudder at last and rotates.
On the arm body of described lower shake-changing arm 3 and upper rocker arm 10, be provided with auxiliary hole 3a, 10a.
Claims (2)
1. rigid rudder driver, comprise lower shake-changing arm (3) and upper rocker arm (10), lower shake-changing arm (3) is positioned at the oblique below of upper rocker arm (10), the middle part kink of this lower shake-changing arm (3) is in the upper end of lower supporting rod (12), the middle part kink of described upper rocker arm (10) is in the lower end of upper supporting column (9), it is characterized in that: between described lower shake-changing arm (3) and upper rocker arm (10), be provided with turning cylinder (7), the lower end warp of this turning cylinder (7) Hooke's coupling (4) down links to each other with the middle part of described lower shake-changing arm (3), and the upper end of turning cylinder (7) links to each other through the middle part of last universal joint (8) with described upper rocker arm (10).
