Abstract
A kind of effective light-duty civilian unmanned plane wheel electro-magnetic braking device, the utility model structure is simple, reliable operation, easy to maintenance, with low cost, effectively can brake in the process of light-duty civilian UAV Landing.This braking device forms primarily of friction disk, limit spring, electromagnet, electromagnet stent and adjusting screw, electromagnet is fixed on the front end of support, the axial clearance of itself and friction disk is adjusted by adjusting screw, limit spring is for preventing braking device when being subject to external disturbance and too much collision occurs electromagnet, certain cushioning effect is played to moving axially of carrying out in permission range of friction disk, to keeping the stable of friction disk in the process of light-duty UAV Landing simultaneously.During braking, electromagnet energising is by friction disk adhesive, and then produces frictional force and friction torque and brake wheel, shortens the coasting distance of unmanned plane during landing and sliding, alleviates impact and restriction that landing place uses unmanned plane.
Description
Art
The utility model relates to a kind of light-duty unmanned plane wheel electro-magnetic braking device, particularly to land and the braking of mild region is more reliable at low speed, effectively can shorten the coasting distance of unmanned plane.
Background technique
At present, the calutron for braking forms primarily of coupling, spring sheet, armature, friction disk, coil, yoke, flange plate, axle, pedestal.During braking, electromagnet is energized, and produces electromagnetic force, the armature of its opposite side is held, electromagnet and yoke mutually extrude and produce pressure and be applied on friction plate therebetween, thus produce frictional force and friction torque, rotor are served to the effect of retarding braking.But, the existing electro-magnetic braking device being applicable to light-duty civilian unmanned plane wheel is less, be generally used for some packeres, cutting machine, wrapping machine, the automation equipment fields such as shock machine, the electro-magnetic braking device cost being applicable to aforementioned device is high, weight is large, installation and maintenance are loaded down with trivial details, and it is larger to requirements of installation space, if using the electro-magnetic braking device of this type of electro-magnetic braking device as the wheel of light-duty unmanned plane, the quality of Landing Gear System can be caused overweight, when landing, undercarriage can bear larger load, also larger moment of flexure can be born in the process of braking, although therefore common electro-magnetic braking device is better at the practical application effect in automation equipment field, but and it is simple and reliable not meet light-duty civilian unmanned plane brake device structure, lightweight, requirement easy to maintenance.
Summary of the invention
Comparatively large and the deficiency of light-duty civil aviation unmanned plane can not be applicable in order to overcome existing electro-magnetic braking device weight, volume, the utility model provides a kind of electro-magnetic braking device, this braking device effectively can not only be braked when Small Civil UAV Landing, shorten the coasting distance of unmanned plane, and have structure simple, lightweight, take that installing space is little, the advantage of reliable operation.
The technological scheme adopted that the utility model solves its technical problem is: for the ease of the installation of braking device annex, has redesigned wheel hub, and be the electromagnet of 12V by voltage rating, electromagnet bearing, friction disk carry out axial installation.Wheel hub is coordinated with multidiameter shaft by bearing, the inner ring of bearing and multidiameter shaft adopt interference fit, the Main Function of multidiameter shaft is support accessory, only bears moment of flexure and does not bear torque, and therefore multidiameter shaft adopts the material lightweight, intensity is high and carries out Surface heat-treatent and improves its intensity further.The process of annular knurl line is carried out on the surface of friction disk, object increases surface roughness, in the process that light-duty unmanned slide is braked, increase frictional force and friction torque thus obtain better braking effect, in addition, friction disk can in the enterprising line slip of axial guidance, but need the limit spring by rigidity is less to carry out axial limiting, simultaneously object prevents from the surface of friction disk and electromagnet from producing too much impact to play certain damping effect, gap control between electromagnet and friction disk is within 1mm, this gap can be regulated by adjusting screw, to guarantee reliability and the validity of braking device in different situations.When light-duty civilian UAV Landing, in order to shorten its coasting distance, controlling electromagnet by remote terminal and connect and produce electromagnetic force, holding friction disk, braked by frictional force therebetween and friction torque.
The beneficial effects of the utility model are, compare braking device compared with before-improvement, and under the prerequisite ensureing new pattern braking efficiency, the installation weight after improvement is lighter, and the space that installation takies is less, and structure is simpler, safeguards more convenient.Known through consulting existing electro-magnetic braking device parameter, the weight of the traditional electrical magnetic detents close with braking moment of the present utility model is 910g, and weight of the present utility model is only 146g, through actual measurement, the electromagnetic force of this model electromagnet can reach 180N, meets the requirement of electro-magnetic braking device to electromagnetic force, in addition, small volume of the present utility model, is only 152cm
3, and installing space shared by traditional electro-magnetic braking device minimum be 173cm
3.Because mounting type of the present utility model adopts external installation, one of main object is namely easy to maintenance, major maintenance work of the present utility model comprises the friction disk changing serious wear, change electromagnet, for loss and not serious friction disk can by the adjusting screw gap adjusted between electromagnet and friction disk ensure brake reliability.
