[0035] It should be noted that a receiving space for receiving other components is formed in the housing 100, so that other structures are suitable for being constructed in the receiving space, so that the housing 100 is suitable for protecting other structures to improve the performance of the gas-air compound steering gear 10. A mounting seat 200 is provided in the housing 100, and the rudder wing 300 is suitable for being arranged on the mounting seat 200 in a rotating manner to transmit the rotation effect, and a rudder shaft 400 is provided at one end of the rudder wing 300, so that the rudder wing 300 is suitable for driving the rudder shaft 400 to rotate. At the same time, the transmission assembly 500 is connected to the rudder shaft 400, so that the rudder shaft 400 is suitable for driving the transmission assembly 500 to transmit and drive the rudder plate to rotate to form or adjust the performance of the gas-air compound steering gear 10.

[0036] During the use of the transmission assembly 500, the first transmission member 510 is suitable for being connected to the rudder shaft 400 so that the rotation effect of the rudder shaft 400 is suitable for being transmitted to the first transmission member 510, and the second transmission member 520 is transmission-connected to the first transmission member 510, and the third transmission member 530 is transmission-connected to the second transmission member 520 so that the rotation effect is suitable for being transmitted to the rudder plate through the third transmission member 530 to drive the rudder plate to rotate, thereby driving the rotation of the rudder plate to constitute the adjustment of the use performance of the gas-air compound servo 10.

[0037] According to the gas-air compound servo 10 of the embodiment of the present invention, a transmission assembly 500 as shown above is provided in the gas-air compound servo 10, and the transmission assembly 500 has a first transmission member 510, a second transmission member 520 and a third transmission member 530 which are sequentially arranged for transmission.

[0038] In some embodiments, a first limiting portion 401 is provided at the end of the rudder shaft 400, and a second limiting portion 511 is provided at one end of the first transmission member 510, and the first limiting portion 401 is limitedly matched with the second limiting portion 511. In this way, by providing the first limiting portion 401 at the end of the rudder shaft 400, the first limiting portion 401 is suitable for being limitedly matched with the second limiting portion 511 on the first transmission member 510, so that the rotation effect on the rudder shaft 400 can be more reliably transmitted to the transmission assembly 500 to realize the rotation drive of the rudder plate, thereby making the control and use of the gas-air compound steering gear 10 more reliable.

[0039] In some specific embodiments, one of the first limiting portion 401 and the second limiting portion 511 is a limiting protrusion, and the other of the first limiting portion 401 and the second limiting portion 511 is a limiting groove, and the limiting protrusion is limitedly arranged in the limiting groove. It can be understood that by setting the first limiting portion 401 and the second limiting portion 511 as the limiting protrusion and the limiting groove respectively, the limiting connection between the first limiting portion 401 and the second limiting portion 511 is made more reliable, so that the transmission effect between the rudder shaft 400 and the first transmission member 510 is more stable, so that the rudder shaft 400 is suitable for rotation under the control of the transmission assembly 500 to improve the performance of the gas-air compound steering gear 10.

[0040] In some embodiments, a third limiting portion 512 is provided at the other end of the first transmission member 510, a fourth limiting portion 521 is provided at one end of the second transmission member 520, a fifth limiting portion 522 is provided at the other end of the second transmission member 520, and a sixth limiting portion 531 is provided on the third transmission member 530. The third limiting portion 512 and the fourth limiting portion 521 are arranged through the transmission of the first limiting member, and the fifth limiting portion 522 and the sixth limiting portion 531 are arranged through the transmission of the second limiting member.

It should be noted that, since the third transmission member 530 is on the side away from the rudder plate, so that the third transmission member 530 is suitable for connecting with the fourth transmission member 540 to drive the fourth transmission member 540 to move, and the fourth transmission member 540 is also suitable for slidably connecting with the sliding member 550, the sliding member 550 is suitable for limiting the moving direction of the fourth transmission member 540, so that the third transmission member 530 can transmit the force to the rudder plate for rotation according to the design.

[0044] In some embodiments, the gas-air hybrid steering gear 10 further includes: a slide rail 700, a slide groove is provided on the slide member 550, and the slide groove is slidably arranged on the slide rail 700. In this way, by sliding the slide rail 700 and the slide groove on the slide member 550, the slide member 550 can move under the guidance of the slide rail 700, so that the force is suitable for being transmitted to the steering plate through the third transmission member 530 to drive the steering plate to move.
