Description

Steering engine for aircraft

Technical Field

The utility model relates to an aircraft field, concretely relates to steering wheel for aircraft.

background

An aircraft is an instrumental flying object that is manufactured by humans, can fly off the ground, flies in space, and is controlled by humans to fly in the atmosphere or in an extraatmospheric space. Steering engines are one of the most important components on aircraft. In the aspect of aerospace, the steering engine is widely applied, and pitching, yawing and rolling motions of attitude transformation of the aircraft are completed by mutual cooperation of the steering engine.

The steering engine of the aircraft is a device for controlling the flight direction of the aircraft. The adjustment of the aircraft in the pitching, left and right directions is adjusted by the steering engine. In the steering engine, each rudder sheet is controlled by an adjusting component. The adjusting component controls the rotation angle of the rudder sheet, so that the flight direction of the aircraft can be adjusted. When the adjusting component directly adopts motor and gear to carry out the rudder axle rotation of rudder piece, can be unfavorable for the state that each operating mode sound that monitored control system gathered the aircraft comes the analysis aircraft because gear drive produces the noise. On the premise of certain manufacturing cost, gear noise is a defect which cannot be avoided by a gear type rudder shaft driving device.

the prior art CN108286918A discloses a multi-axis driven annular steering control device. Although the prior art cancels gear transmission, an adjusting assembly consisting of a motor, a screw rod, a shifting fork and a nut is adopted, the motor drives the screw rod to rotate, the screw rod drives the screw rod to move along the axial direction, the shifting fork is clamped into a notch on one side of the nut far away from the motor, and the shifting fork is fixedly connected with a rudder shaft. In the driving mode, the gap is open, so that the nut can only drive the shifting fork to one side far away from the motor, and the shifting fork cannot be pulled back, so that the rudder shaft can only rotate towards one direction and cannot be reversed, and the basic function requirements of the forward and reverse rudder shaft cannot be met; meanwhile, the rotation of the rudder shaft in two directions can be realized in time through the shifting fork, but in the matching mode of the shifting fork and the nut, when the matching gap is too small, the action locking is generated, and the shifting fork cannot be smoothly pushed; when the clearance is too large, the shape error is extremely large, the rotating position of the rudder shaft cannot be adjusted in time, and the rotating angle of the rudder shaft cannot be controlled accurately.

furthermore, prior art CN106976550A discloses an aircraft rudder and air rudder linkage. The prior art also cancels gear transmission, the adjusting component of the rudder piece comprises a lead screw nut, an action rod and a cam which are sequentially hinged, the lead screw nut is matched with a lead screw, the rudder piece is in threaded connection with the cam, the cam is in threaded connection with a gas rudder support, and the gas rudder support is fixed on the outer cover. Although the connecting rod type adjusting assembly has extremely low transmission noise compared with gear driving and shifting fork driving, the transmission stability can be ensured, and adverse factors such as errors can not be generated. However, the transmission chain of the link mechanism type adjusting assembly is too long, which not only increases the transmission error, but also increases the volume and gravity of the rudder piece driving device, and thus the link mechanism type adjusting assembly cannot be developed on the fly smoothly.

Disclosure of Invention

The utility model aims at: the utility model provides a steering wheel for aircraft has solved the transmission chain overlength of current steering wheel, leads to the transmission error increase, the problem that its self gravity also increases.

In a link mechanism adopted by the existing steering engine, if an action rod for connecting a lead screw nut and a cam is directly cancelled, the lead screw nut is directly hinged with the cam, at the moment, the driving motor is fixed relative to the rotation center of the cam, and the lead screw nut has only one position, so that the lead screw nut is positioned on a lead screw and is hinged with the cam; at the moment, the feed screw nut cannot move, and meanwhile, the cam cannot rotate around the rotation center of the cam. The purpose of reducing the volume and the gravity can be achieved by removing one connecting rod, but the screw nut and the rudder shaft cannot be moved, so that the position of the motor needs to be synchronously adjusted along with the movement of the screw nut, and the screw nut serving as a driving piece can be hinged with the cam and can also move along the screw rod. In order to meet the above requirements, an additional motor is required to adjust the position of the driving motor, which in turn increases the complexity, volume and gravity of the overall structure of the link mechanism type driving mechanism, contrary to the technical problems to be solved at first.

And the utility model discloses a steering wheel for aircraft has broken through traditional inertia thinking of fixing orthoscopic actuating mechanism on the part on the basis of having cancelled a connecting rod among the current connecting rod formula adjusting part, fixes the part that supports the rudder axle with actuating mechanism articulated formula innovatively, on the fixed plate promptly, and the fixed plate is fixed on the shell of aircraft, and actuating mechanism can rotate around its and the articulated axis between the fixed plate. Specifically, when the screw rod drives the slider to move, because the rudder blade rocker can only rotate around the axis of the rudder shaft, and the slider needs to move axially along the screw rod, the slider rotates around the rudder shaft together with the rocker under the drive of the screw rod, and the slider enables the linear driving mechanism to rotate around the axis of the hinge part between the driving mechanism and the fixed plate under the guidance of the rudder blade rocker, so that the output end of the driving mechanism is continuously adjusted to match the rotation of the slider, and the movement mode of the slider is planar motion: the slide moves linearly relative to the drive mechanism and rotates about the axis of rotation of the rudder blade pivot, i.e. the axis of the rudder shaft, relative to the rudder blade pivot.
