Abstract
The invention provides a self-locking electric steering engine which comprises a motor, a speed reducer, a control surface and a brake, wherein the brake comprises a brake shell, at least three guide posts, a permeability magnetic material brake pressure plate, a nonmetallic brake plate, a spring and an electromagnet, wherein the guide posts are vertically fixed on an end face of a non-drive end of the motor and circumferentially distributed;, the permeability magnetic material brake pressure plate can freely slide along the direction of the motor shaft under the guidance of the guide posts; the nonmetallic brake plate is coaxially and fixedly connected with the non-drive end of the motor shaft and is parallel to the brake pressure plate; the spring is arranged between the brake shell and the brake pressure plate and through which the brake pressure plate can tightly press the brake plate; the electromagnet can keep the brake pressure plate away from the brake plate; and the brake shell is arranged at the non-drive end of the motor; and the electromagnet, the spring, the brake pressure plate, the brake plate and the guide posts are arranged in the brake shell. In the invention, the brake is arranged at the tail end of the most primary level of drive (motor), and the aircraft control surface can obtain the maximum self-locking torque in the case of the same size due to the torque amplification action of the speed reducer, thus the size of the brake can be very small, but the structural reliability is very high.
Description
Technical field
The present invention relates to a kind of electric steering engine.
Background technology
Electric steering engine is the aerodynamics execution unit of aircraft flight.Under "on" position, the electric steering engine output torque drives the vehicle rudder diversion air, the flight of assisting in flying device.The type of belt drive of conventional electric steering wheel is: motor---decelerator---rudder face is referring to Fig. 1.In use the conventional electric steering wheel does not have self-lock ability, and the electric steering engine of aircraft flies the stage no power at extension, and rudder face will be subjected to the impact of air, produces swing, the safety that very likely threatens aircraft.For guaranteeing that aircraft flies over safety in the journey at the obstructed cable address of electric steering engine, is necessary to suppress the passive swing of vehicle rudder during obstructed cable address flies.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technology, the invention provides a kind of self-locking electric steering engine.
Technical solution of the present invention is: a kind of self-locking electric steering engine, comprise motor 1, decelerator 2 and rudder face 3, it is characterized in that: also comprise brake, described brake comprises brake casing 9, be vertically fixed on the motor anti-drive end end face and at least three leads 7 of circle distribution, the permeability magnetic material brake press plate 6 that can be free to slide in the guiding lower edge of lead motor shaft direction, be connected and the nonmetal keep plate 8 parallel with motor shaft anti-drive end 10 is coaxial with brake press plate 6, be arranged on and be used for the spring 4 that brake press plate 6 compresses keep plate 8 between brake casing 9 and the brake press plate 6, can make the electromagnet 5 of brake press plate 6 away from keep plate 8; Described brake casing 9 is arranged on the anti-drive end of motor 1, and described electromagnet 5, spring 4, brake press plate 6, keep plate 8 and lead 7 are arranged in the brake casing.
Above-mentioned keep plate 8 is the bakelite plectane.
Advantage of the present invention:
1, the present invention uses brake in electric steering engine, and aircraft is increased substantially in the stability that obstructed cable address flies under the impact of stage rudder face at air.
2, self-locking electric steering engine of the present invention is arranged on brake the tail end of transmission initial stage (motor), because decelerator is to the amplification of moment, vehicle rudder can obtain maximum self-locking moment under identical size, so brake dimensions can be very little, but structural reliability is very high.
Description of drawings
Fig. 1 is the structural representation of conventional electric steering wheel schematic diagram;
Fig. 2 is the structural representation of self-locking electric steering engine of the present invention;
Position view when Fig. 3 is self-locking electric steering engine brake release of the present invention;
Position view when Fig. 4 is self-locking electric steering engine brake self-locking of the present invention;
Wherein: 1-motor, 2-decelerator, 3-rudder face, 4-spring, 5-electromagnet, 6-brake press plate, 7-lead, 8-keep plate, 9-brake casing, 10-motor shaft anti-drive end.
The specific embodiment
Referring to Fig. 2, the self-locking electric steering engine, comprise motor 1, decelerator 2, rudder face 3, brake, brake comprise brake casing 9, be vertically fixed on the motor anti-drive end end face and four leads 7 of circle distribution, the permeability magnetic material brake press plate 6 that can be free to slide in the guiding lower edge of lead motor shaft direction, be connected and the nonmetal keep plate 8 parallel with motor shaft anti-drive end 10 is coaxial with brake press plate 6, be arranged on and be used for the spring 4 that brake press plate 6 compresses keep plate 8 between brake casing 9 and the brake press plate 6, can make the electromagnet 5 of brake press plate 6 away from keep plate 8; Keep plate 8 is the bakelite plectane, and brake casing 9 is arranged on the anti-drive end of motor 1, and electromagnet 5, spring 4, brake press plate 6, keep plate 8 and lead 7 are arranged in the brake casing.
Brake is under cold state, and brake press plate compresses the bakelite plectane under the effect of spring force, thereby forms the self-locking moment of motor, and this self-locking moment impacts with the air that the opposing rudder face is subjected at the moment of torsion amplification metapedes through decelerator.After the energising, electromagnet produces magnetic force, and brake press plate overcomes spring force and moves along lead under the effect of the magnetic force of electromagnet, unclamp the bakelite plectane, and motor returns to normal operating conditions.
The type of belt drive of self-locking electric steering engine of the present invention is: brake---motor---decelerator---rudder face.
