Abstract

The utility model discloses a bicycle expansion brake with a generator, comprising a claw pole permanent magnet generator which is arranged in an expansion case, and the expansion case is axially lengthened along the braking wheel. The utility model is suitable for lighting and power supplying when the bicycle is running at night, and meanwhile, the utility model has the braking function of common expansion brakes.

Description

Bicycle brake with generator

The utility model relates to a kind of bicycle expansion brake with electrical generator, is applicable to illuminalive power-supply when riding bicycle night, has the drag function of the common lock that rises simultaneously.

Ride night bicycle and when not having illumination such as street lamp again need carry light equipment.Existing bicycle lighting equipment has: flash light, battery powered headlight, the headlight that " rubs " and power, and by the headlight that is contained in the generator powered on the wheel shaft, also has my application in addition, and in " the bicycle band-type brake of band electrical generator " of bulletin on October 7th, 87, notification number is GG86210394." the bicycle band-type brake of band electrical generator " compares the advantage with not power consumption pond with " bicycle expansion brake of band electrical generator " with the light equipment power supply with battery, compare with " rubbing " have ride laborsaving, and be applicable to any weather and road conditions condition, can and not make transmission failure as the easy quilt muddy obstruction friction wheel of " rubbing " machine, and electrical generator combines with the band-type brake or the lock that rises, reduced cost in the time of convenient the use again, has visibly different use zone at rise lock and band-type brake of China, south is many with the lock that rises, and band-type brake is used in the north more.

The purpose of this utility model is to provide a kind of bicycle expansion brake with electrical generator, it is integrated the electrical generator and the lock that rises, thereby has all advantages of the electrical generator that is installed on the wheel shaft, has remedied its shortcoming simultaneously again, and reduced total cost, made things convenient for use.

The utility model partly is made up of the master section and the lock that rises, and the utility model is elaborated below in conjunction with accompanying drawing: figure one is the master section front elevation after the utility model folding removes the lock part that rises.Figure two is cutaway views of the present utility model.Wherein 1 is the claw pole electric generator stator, 2 is the dynamo armature winding, 3 is the electrical generator p-m rotor, 4 are the lock brake wheel that rises, and 5 are the lock brake shoe that rises, and 6 is the electrical generator output wiring terminal, 7 are the lock protecting cover that rises, 8 are the lock force transmission mechanism part that rises, 9 for generator claw pole stator 1 with rise by pad or other upholder between the lock brake shoe 5, prevent that brake shoe is attracted to the supporting role of p-m rotor.Remainder comes into plain view, and need not to give unnecessary details.Wherein 1,3,2,6 is master section of the present utility model, and 9 is the middle transition part, and remaining is the lock part that rises, and except that rising by the lock brake axle to lengthening, other is identical with the common lock that rises.For simplicity's sake, the force transmission mechanism of the lock that rises, fasteners etc. all do not draw.

In sum, the characteristics of the utility model maximum are that electrical generator is contained in common having risen in the lock that process has been changed, thereby to using the bicycle headlight that a fit closely power supply is provided, and additional conditions are not proposed to using, be adapted to the environment that Regular Bicycle can be suitable for.Install also identical with the common lock that rises.When using product of the present utility model, only need through a switch to close a switch when this wheel from the wire to terminal to the headlight, electrical generator promptly begins generating, and lamp is just bright.Cut-off switch, electrical generator then are in light condition.

Claims

A kind of bicycle expansion brake that is applicable to the band electrical generator of illuminalive power-supply when making bicycle rides night, it is made up of the lock that rises that a pawl pole magneto generator and brake wheel have extended, the pawl pole magneto generator and the interior parallel installation of brake shoe of lock of rising, the centre is lined with a pad, it is characterized in that the pawl pole magneto generator is contained in the lock brake wheel that rises.
