Abstract

The utility model relates to a high speed bicycle pedaled by the manpower. The utility model is mainly composed of existing bicycle parts such as a front and a back wheels, a handle bar, a cross beam, a saddle, a flywheel, and a pedal wheel, wherein, the cross beam body is fixedly provided with a combined wheel frame; the combined wheel frame is fixed with a combined wheel shaft, both ends of the combined wheel shaft are respectively provided with a combined big wheel and a combined small wheel, and the combined big wheel and the combined small wheel are respectively connected with the flywheel and the pedal wheel through the combined wheel chain. The utility model has the advantages of simple structure, low cost, convenient operation, high speed, accordance with the physical strength of the rider, body-building function, and no other energy sources consumption.

Description

High speed bicycle

The utility model relates to the high-speed bicycle that the bicycle that a kind of manpower scrunches, particularly manpower scrunch.

It is existing that to scrunch the bicycle speed that travels by manpower slower, generally per hour about about 20 kilometers, existing variable speed bicycle can reach about 30 kilometers when high speed, and adopts the bicycle of the forms that are used as power such as electricity or diesel oil, speed also only is the 30-40 kilometer, and its complex structure, cost is higher, and manoevreability is relatively poor, expend the energy again, contaminated environment, therefore, the latter seldom adopts in practice.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, designs a kind ofly to scrunch by manpower, does not expend other propulsions source, the speed height, and simple in structure, manoevreability is good, the high-speed bicycle of non-environmental-pollution.

The purpose of this utility model realizes by following technical proposals: it comprises the front-wheel 1 of existing bicycle structure, handlebar 2, car beam 3, vehicle seat 9, brake 10, trailing wheel 12, flywheel 13, pedal wheel 14, pedal 15, it is characterized in that also comprising combination wheel carrier 4, combination bull wheel 5, combination wheel shaft 6, combination steamboat 7, combination endless chain 8, spring delays lock 11, combination endless chain 16, wherein on car beam 3 beam bodies, be provided with and be fixed with combination wheel carrier 4, on combination wheel carrier 4, be fixedly connected with the combination wheel shaft 6 of horizontally set, end at combination wheel shaft 6 is fixedly connected with square with the axis combination bull wheel 5, the other end at combination wheel shaft 6 is fixedly connected with square with the axis combination steamboat 7, combination bull wheel 5 and combination steamboat 7 rotate synchronously with combination wheel shaft 6, place, wheel outer at combination bull wheel 5 is provided with the gear teeth, one end movable sleeve of the combination endless chain 8 of closed circular is nibbled the gear teeth place at combination bull wheel 5, the gear teeth of the flywheel 13 that its other end and trailing wheel 12 wheel shaft places are fixing movable sleeve are mutually nibbled, interconnect transmission and will make up bull wheel 5 with flywheel 13, one end movable sleeve of the combination endless chain 16 of closed circular is nibbled the gear teeth place at pedal wheel 14, its other end movable sleeve is nibbled the gear teeth place that is provided with on combination steamboat 7 outers, interconnect transmission and will make up steamboat 7 with pedal wheel 14.

This bicycle has been set up the slow lock 11 of spring, leans against the steel ring place of front-wheel 1 and trailing wheel 12 respectively, uses the slow lock 11 of spring to make a buffering during brake earlier, then pinches brake 10, to avoid the generation of inertia accident.

The utility model mainly contains with the advantage that above-mentioned prior art is compared:

1, simple in structure, easy to use, cost is lower, and maintaining is more convenient;

2, the speed of a motor vehicle is very fast, per hour can reach about 60 kilometers, and adapt with bicyclist's muscle power, has body-building function;

Though 3, Ben Che has fair speed, do not expend oil or electricity and wait other energy, noiselessness, environmentally safe.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the structural representation of high-speed bicycle.

The embodiment that provides as the utility model accompanying drawing, structure is as indicated above, according to mechanics principle, wheel comes down to a rotary lever, pedal wheel 14 is connected with combination steamboat 7 and combination bull wheel 5 by combination endless chain 16, pedal wheel 14 is directly foot-operated and directly stressed by the bicyclist, the acting point that is equivalent to lever, combination steamboat 7 reaches the stress point that is equivalent to lever by concentric shafts combination wheel shaft 6 coupled combination bull wheels 5, the weight of acting point is greater than the weight of stress point, be the power of the power of acting point greater than stress point, can reach the labour-saving effect, can be designed to pedal wheel 14 2-5 times for combination bull wheel 5 and combination steamboat 7 gross weights, this car is designed to 3.5 times.

The diameter of the pedal wheel 14 of present embodiment is 20 centimetres, the diameter of flywheel 13 is 8 centimetres, and combination bull wheel 5 diameters are 25 centimetres, and combination steamboat 7 diameters are 6 centimetres, the conventional rotating speed of pedal wheel 14 is 0.88 revolutions per second, learns about 65 kilometers/hour of this car speed per hour as calculated.

Be the loss of reducing friction, the bearing of each wheel of this car all adopts antifriction-bearing box.

Combination wheel carrier group and the welding of car beam are fixing about vertically being provided with about the combination wheel carrier 4 of this car adopts.
