Abstract
The utility model relates to a bicycle with an auxiliary boosting gearing. An inertia wheel is arranged on the lateral face of a wheel disc on the bicycle, and a free wheel mechanism arranged between the wheel disc and a centre shaft is formed by the matching of a ratchet wheel and a ratchet pawl. Depending on the inertia effect of the inertia wheel, the inertia wheel still acts on the drive set to cause the bicycle to move ahead when the treading force and the riding force are relieved, and the purposes of acceleration and labour saving are realized. The retrofit part of the utility model provides a simple structure and an obvious action effect, and the utility model is suitable for civil use and sports competition.
Description
The utility model relates to a kind of bicycle and man, and is specifically a kind of with the auxiliary bicycle that adds force actuators.
Existing bicycle and man includes handlebar, vehicle frame, front and back wheel and actuating device, includes axis, pedal, wheel disc, chain and flywheel etc. in the actuating device.The wheel disc of ordinary bicycle and the diameter of flywheel are selected, and are to guarantee that to pedal the power of riding moderate realizing making under certain vehicle speed condition, to satisfy popular physiological situation.And as the racing car of competing for the sportsman and using, then be a kind of structure design that adds big trochal disc and flywheel diameter difference, increase transmitting ratio with this, thereby improve the speed of a motor vehicle, but the power of pedaling simultaneously also increases exponentially.Be the raising of the bicycle speed of a motor vehicle, pedaling the power of riding with increasing is cost.
The purpose of this utility model just provides a kind of bicycle new construction, with when improving the speed of a motor vehicle, reduces to pedal and rides strength, thereby reach quick labour-saving purpose.
The utility model is achieved in that the wheel disc side in actuating device adds an inertia wheel on existing bicycle basis, constitutes flywheel mechanism by ratchet, click-fit between wheel disc and the axis.Promptly in bicycle, include two flywheels that freely rotate on wheel disc place and the rear axle.Inertia wheel and wheel disc are fixed into one, because the diameter of inertia wheel less than wheel diameter, is positioned on and is vacant state on the axis, thereby himself rotary resistance is little, the antagonistic force that acts on to pedal is also less, promptly pedals the strength of riding and does not strengthen because of increasing inertia wheel substantially.People's the power of pedaling acts on inertia wheel and rear flywheel by the wheel disc flywheel mechanism, and bicycle is advanced.Because inertia wheel and wheel disc are with constituting flywheel mechanism between the axis that connects pedal, make inertia wheel not because of stopping to pedal, but equally be rotated further with front and back wheel, and because of producing certain rotor inertia after the inertia wheel rotation, under effect of inertia, the driven wheel disc spins, actuating device still moves, the driving bicycle advances, and can save thus to pedal the strength of riding.The speed of a motor vehicle is fast more, and the inertia wheel rotating speed is high more, and velocity inertial is big more, and its strength that acts on bicycle is big more, can significantly alleviate the power of riding of pedaling.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a local structure scheme drawing of the present utility model.
Fig. 2 is the local structure scheme drawing of actuating device.
As shown in drawings, 1 is vehicle frame, and 2 is trailing wheel, comprises axis 3, pedal 4, wheel disc 5, chain 6 and flywheel 7 in the actuating device.Be added with inertia wheel 8 in wheel disc 5 sides, constitute flywheel mechanism by ratchet, click-fit between wheel disc and the axis 3.Relatively ordinary vehicle type and five fast derailleurs, the wheel disc in this device still is single leaf form, and for ten speed derailleurs, the wheel disc in this device then is the double leaf form, and as shown in Figure 2, the flywheel form on the rear axle is consistent with existing bicycle still.
Inertia wheel 8 adopts metallic material to make, and the 20-40% of weight control car weight when not adding inertia wheel, diameter are the 1/2-2/3 of front and back wheel diameter.For improving its rotor inertia, should strengthen the weight of the wheel limit part of inertia wheel.Inertia wheel and wheel disc can be integrally manufactured moulding, also can pass through the attaching parts captive joint.
For further improving the safety braking performance of this bicycle, on the basis of existing front and back wheel braking, also can one stop mechanism be set in inertia wheel edge, inertia wheel is to the application force of actuating device when reducing brake.
The utility model is by adding a cover inertia wheel and a rotary flyweights mechanism in actuating device, make and the time added a propulsive effort, and with the increase of the speed of a motor vehicle, this additional drives power increases synchronously in driving, thereby ride power simultaneously pedaling of the corresponding person of riding of alleviating, can improve the speed of a motor vehicle.When doing automobile race, adopt and identical pedal the power of riding and then can improve results, when doing civilian vehicle and use, keep the identical speed of a motor vehicle then can save muscle power.This bicycle modified segment is simple in structure, and action effect is obvious, is suitable for civilian and the sports tournament use.
