Abstract

an electric generator for bicycle or tricycle has left and right hangers on its front end cover for fixing it to back fork and rear axle. A clutch at the front end of rotor axle acts on small flygear engaged with big gear of rear wheel hub. Said big gear plays the role of both storing and releasing mechanical energy and drives rotor to form rotary magnetic field. Under the drive of big gear, the smal flygear has high speed, making the rotational inertia of rotor higher than rotation speed of small flygear. As a result, small flygear slides and shows no resistance to rear wheel.

Description

A kind of bicycle transmission rotor machine and generator

The present invention relates to a kind of magnet steel rotator type alternating current generator of bicycle and pedicab, especially for the device of trailing wheel rotating generator rotor.

The preceding axle head of its rotor of generator that present prior-art devices is used for bicycle lighting contacts with the wheel cover, utilize wheel rolling frictional force to make rotor form rotating magnetic field, when vehicle wheel rotational speed reduces, generator voltage descends thereupon, this class generator is because power output is little, so do not have enough electric power to throwing light on the car, also have such problem in addition: before the rotor between axle head and the cover during pressure tension frictional force also big, make wheel continue to roll and be subjected to resistance, thereby formed the force of rolling friction in the wheel forward travel; Otherwise pressure is crossed Song Shihui and is caused the rotor axle head to skid between the two, generator voltage is descended or does not generate electricity, owing to there are these shortcomings, this class generator is not widely used in actual product.

Task of the present invention is to provide a kind of resistance wheel that reduces can prevent that again the rotor axle head from skidding for bicycle and pedicab, helps reequiping bigger generator of power and corresponding illumination, charging, the signalling that increases dress and motorcycle said function simultaneously.

Task of the present invention is achieved in that to increase at the corresponding elongation circle of the rear-wheel hub of bicycle and pedicab left side steel ball bearing seat excircle adorns a gear wheel, axle head repacking one has had clutch effect small flygear before generator amature, gear wheel transmission small flygear runs up and makes the rotor rotatory inertia be more than the rotating speed of small flygear, so skidding, small flygear reduced back wheel drag, simultaneously because of being that two gears engaged can not cause and skid; Because it is big that the feature of this device of small flygear more can help the rotor rotatory inertia, so reequiped bigger generator and corresponding illumination, charging, the signalling that increases dress and motorcycle said function of power

The present invention only needs increase at rear-wheel hub and adorns a gear wheel, to other structure of bicycle or pedicab without any special requirement, so structure is simple especially; While is bigger owing to rear-wheel hub increases the quality that behind the dress gear wheel trailing wheel is rolled forward, so both played the trailing wheel storage and discharged mechanical energy, plays transmission rotor formation rotating magnetic field again; Because be that gear wheel transmission small flygear can not cause and skids, frictional force is also little between the two simultaneously, the resistance that is subjected to is also little so that wheel rolls forward; Because gear wheel transmission small flygear runs up and makes the rotor rotatory inertia be more than the rotating speed of small flygear, so small flygear skids and has reduced back wheel drag, owing to reequip bigger generator of power output and signalling in addition, institute thinks that traffic safety has played guarantee effect.

Below the present invention is further detailed explanation:

This generator belongs to magnet steel rotator type alternating current generator together, and six windings are arranged in the stator, and rotor has six permanent-magnet ferrites, and along garden Zhou Junbu, during the rotation of magnet steel rotor, the stator winding of magnet steel periphery produces alternating current.After connecting separately, six stator winding become A, B, three power supplies of C winding respectively, the end of a thread parallel connection of A, B, three windings of C, and three line tail output leads as single-phase alternator also in parallel; Its internal circuit principle is identical with Honda C90 motorcycle magnet steel rotator type generator, and the rotor rear axle is equipped with rolling bearing is contained in the rear cap bearing support of aluminum bearing; Front axle is equipped with equally and makes axle head stretch out the outer usefulness as the dress small flygear of protecgulum in the front end housing bearing holder (housing, cover) of the rolling bearing and the aluminum of packing into; Respectively there is a hanging feet in second garden of front end housing about week.

Be processed into screw thread garden week outside the axle head before the rotor and connect into integral body, the appropriate gap distance is arranged between small flygear and the front end housing as double-screw bolt and small flygear inner hole thread.

Rear-wheel hub left side steel ball bearing seat elongation circle is processed into screw thread in outer garden week equally and the gear wheel inner hole thread connects into integral body.

The installation of generator: screw off rear axle left side nut and take off left socles such as back mud plate, clothes hanger, car support from rear axle, the right hanging feet inner hole sleeve of generator on rear axle, again car support, supports such as clothes hanger, mud plate load onto and screw in rear axle nut; The center, both sides up and down of left side hanging feet endoporus aligning rear fork is bored 0.9 centimetre of hole and is penetrated connection and screw in nut with 0.8 centimetre of bolt, adjusts at last and tightens left and right sides hanging feet nut again after small flygear and gear wheel mesh, and makes generator become whole with the back vehicle frame.

Have equally in garden week outside a front hub left side or the right bearing seat ring and can adorn a gear wheel and the engagement of generator amature front axle small flygear.

As previously discussed, can also be before generator axle head adorn a small flywheel and front or rear wheel cover tire and roll and coincide, utilize the transmission rotor that coincide also to make its rotatory inertia be more than the small flywheel rotating speed, small flywheel is skidded reduce resistance wheel.

For convenient adjustment small flygear and the engagement of canine tooth flywheel, so should make the diameter of generator left and right sides hanging feet endoporus slightly larger.

Sitting down at car, the gap increases and adorns a storage battery roll-over protective structure between face and the back clothes hanger.

Silicon rectifier should separate with generator makes its car of packing into sit the inside, and the benefit of doing like this can shorten generator.
