ELECTROMECHANICAL DEVICE FOR VEHICLE WHEELS

摘要

FIELD: electrical engineering; conversion of kinetic energy of rotating wheel into electric energy for consumers installed on wheels for instance, light sources installed on vehicle wheels. SUBSTANCE: electromechanical device has ac generator 5 and lighting unit 6 with light-emitting diodes 16 arranged in housing of decorative cap 4. Housing of decorative cap 4 is secured on vehicle wheel 2 so that it can be removed, generator 5 has stator 7 secured in housing of decorative cap 4 coaxially with wheel 2 and cylindrical rotor 8 with weight 10 eccentrically secured on end part of shaft 9. Weight 10 prevents rotation of rotor 8. Light-emitting diodes 16 are grouped and connected to leads 12 of winding of stator 7. Light-emitting diodes of each group are connected in parallel with loads of winding of stator 7. Light-emitting diodes of one subgroup are connected opposite to light-emitting diodes of other subgroup. Number of light-emitting diodes in one subgroup is equal to that in other subgroup. Housing of decorative cap 4 serves as protective cap of wheel 2. Light-omitting diodes are arranged on face surface of housing of decorative cap 4 and are protected by transparent shield 21. EFFECT: provision of stable (non-rotating) image of information or decorative character on vehicle rotating wheel at running owing to stroboscopic effect, simplifiede mounting and dismounting of device from wheel, combination of functions of protective cap and information or decorative panel. 3 dwg
