Description

A kind of bicycle generating set

A kind of bicycle generating set is a manually driven miniwatt power generation assembly, uses for illumination and other electricity consumption facilities.

Evening, that was just convenient much capable if illuminating lamp is arranged by bike particularly in the rural area by bike, and this is very helpful for accelerating road speed and minimizing accident, in addition enriching along with the Social Culture life.People are riding instead of walk by bike or also can watch that theatrical items or the radio step talks during body-building, and these all need power supply, and the available battery that provides of power supply solves certainly, can use flash light as illumination, but so use inconvenience, also will often change.Though sell on the current market bicycle dynamo arranged, but this bicycle dynamo is wiped the rotation generating by cycle wheel and electrical generator, the resistance considerable influence by bike on the one hand, bicycle is easier to because of the frictionally damage tire on the other hand, whole tire can damage very soon, and change of wheels had often both bothered and spent bigger.

The purpose of this utility model is to manufacture and design a kind of bicycle generating set, to overcome current bicycle generating damage wheel and to pedal the shortcoming of effort.

The purpose of this utility model is achieved in that a kind of bicycle generating set, comprise the axletree (1) that overlapped king wire dish (3) and secondary coil of wire (3 '), be fixed in the electrical generator (2) in the clamping bar (12), connect solid king wire dish (3) and secondary coil of wire (3 ') by many steel wires (10) and car volume, place the bearing bore (13) of king wire dish (3) and secondary coil of wire (3 ') and a plurality of balls (6) of (13 '), with ball base (7) and (7 ') of axletree (1) screw thread integrated positioning ball (6), of the present utility model being characterised in that: described electrical generator (2) is fixed in axletree (1) by clamping bar (12), coil of wire (3) has main pulley (11), has the dynamo pulley (4) that is placed in electrical generator (2) and the belt (5) on the main pulley (11).

Take the utility model of above measure, simple and reliable for structure, the whole generating device is in bicycle and axletree medium position, owing to taked the belt rotation, it is comparatively laborsaving therefore to pedal bicycle, has avoided the wheel damage of current bicycle generating simultaneously.

In conjunction with the accompanying drawings the utility model is made into a little detailed description more below:

Accompanying drawing 1 is a constructional drawing of the present utility model.

With reference to above accompanying drawing.King wire dish (3) and secondary coil of wire (3 ') generally are that punching press of steel village or casting form with metallic material, their centers have axis hole can pass axletree (1), there have circumference equal portions hole can be inserted in many steel wires (10) near the edge to be even solid with the car pulling force of bicycle volume, being equipped with ball chamber (13) and (13 ') near the axis hole can hold a plurality of balls (6), the quantity of the volume size of ball chamber (13) and (13 ') and shape and built-in ball (6) can with existing bicycle conformance to standard.The size of king wire dish (3) and secondary coil of wire (3 ') diameter can be consistent, can also do secondary coil of wire (3 ') slightly little, and king wire dish (3) is equipped with main pulley (11), and diameter is about 12 centimetres.Certain secondary coil of wire (3 ') also can be made the same with king wire dish (3) diameter and be equipped with same belt pulley, drives the electrical generator that double end has transmission shaft with belt simultaneously.Main pulley (11) on the king wire dish (3) has V-slot so that be inserted in triangle drive belt (5).Axletree (1) is made with round steel, can be 10 millimeter settings with current bicycle diameter, two ends are equipped with screw thread, screw in that ball base (7) and (7 ') is positioned ball (6) for ball chamber (13) and in (13 '), and by jam nut (9) with the front vehicle fork (8) of bicycle and main shaft (1) even admittedly.Outside the ball chamber (13) of main shaft (1) and king wire dish (3) and secondary coil of wire (3 ') and the rear wall of (13 '), be equipped with ball bowl (14) and (14 '), in adorn a plurality of balls (15) and avoid direct friction to reduce resistance.Clamping bar (12) is made with steel, and is at the medium position of axletree (1) that electrical generator (2) and axletree (1) is even solid.The armature axle head of electrical generator (2) has electrical motor belt (4), and electrical generator (2) can adopt multipole mag-dynamo.Belt (5) adopts triangle dropper drive belt for well.Belt (5) is placed on dynamo pulley (4) and the main pulley (11), can constitutes a bicycle generating set.To be transmitting ratio get final product when above when being made as 5: 1 for main pulley of the present utility model (11) and dynamo pulley diameter ratio, and main pulley (11) is set is 15 cm diameters, 1.5 centimetres of pulley motor (4) diameters, i.e. transmission is through being 10: 1 easy realizations of right and wrong party.Electro-motive force of the present utility model is put the method that metallic channel or drilled in middle aperture draw and is realized with can adopting being connected of outer current consumer on axletree (1).

Claims (1)

1, a kind of bicycle generating set, comprise the axletree (1) that overlapped king wire dish (3) and secondary coil of wire (3 '), be fixed in the electrical generator (2) in the clamping bar (12), connect solid king wire dish (3) and secondary coil of wire (3 ') by many steel wires (10) and car volume, place the bearing bore (13) of king wire dish (3) and secondary coil of wire (3 ') and a plurality of balls (6) of (13 '), with ball base (7) and (7 ') of axletree (1) screw thread integrated positioning ball (6), of the present utility model being characterised in that: described electrical generator (2) is fixed on the axletree (1) by clamping bar (12), king wire dish (3) has main pulley (11), has the dynamo pulley (4) that is placed in electrical generator (2) and the belt (5) on the main pulley (11).
