Abstract
The utility model relates to a power-assisted apparatus for a bicycle, which is composed of a bicycle frame, a front wheel, a speed changing wheel disk and a back wheel. The utility model is characterized in that a moving rod of an automatic accelerator is penetrated in a check ring of a lock ring, and a compression spring is arranged in an outer pipe; a circular ring of the top end of the moving rod is fixed behind a clothes hanger; the lower end of the outer pipe is fixed on a back shaft; a gear and a chain wheel are integrated into a whole; the gear is meshed with a toothed rack; the chain wheel is connected with an accelerating fly wheel by an accelerating chain; the upper end of the toothed rack is connected with the moving rod, the lower end is penetrated and fixed in a square sheath of the bottom part of the outer pipe, and the lower end slides in the square sheath. The utility model converts the shaking force of the drive of the bicycle into the additional force for the advancing movement of the bicycle by the weight of a human body, so that riders feel laborsaving and comfortable at high speed.
Description
The utility model relates to a kind of Accelarators for bicycles, be daily necessities.
China is bikedom, and bicycle of a great variety is as light roadster mountain bike, derailleur or the like, it is very heavy in the control strip control flywheel that the gear shift mode of derailleur has internal speed-changing, make its inner ring separate and close up,, realize that the high, low speed retaining is adjustable by the speed change transmission of gear with overcoat; Outer speed change is to realize by the number of teeth of adjusting big trochal disc and flywheel, no matter be the sort of speed change, the size that must lean on the people to exert oneself by bike realizes the speed of moving velocity.In such cases, human weight and downward application force not only do not make full use of, but also can influence bicycle running speed.
Task of the present utility model is at above-mentioned deficiency, provides a kind of human weight that relies on that the shaking force of bicycle running is transformed into the additional power that bicycle advances, make the cyclist laborsaving, at a high speed, comfortable Accelarators for bicycles.
The utility model is finished in the following way:
The auto acceleration device is made up of tooth bar, gear, sprocket wheel, acceleration chain and compression spring, and is installed between bicycle rear rack and the rear axle.When bicycle running, utilize human weight to add 50% car weight, bicycle is pitched, the power that the speed of a motor vehicle is jolted more soon is just big more, and when compression spring downwards, the gear on the rack drives left side, sprocket wheel by quickening chain, make and quicken flywheel to front haulage; When compression spring rebounded, gear, the sprocket wheel on rack drives the right by quickening chain, made and quicken flywheel to front haulage, and whenever jolting once produces tractive force forward twice.
The utility model is to rely on human weight that the shaking force of bicycle running is transformed into the additional power that bicycle advances, make the cyclist laborsaving, at a high speed, comfortable, it is simple in structure, and is easy to use, reliable.
Fig. 1 is the utility model integral structure figure.
Fig. 2 is the utility model auto acceleration device constructional drawing.
Fig. 3 is the utility model auto acceleration device back view.
Fig. 4 quickens flywheel structure figure for the utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail:
By vehicle frame [1], front fork [2], front-wheel [3], handlebar [4], speed change wheel disc [5], trailing wheel [8], saddle is sat the Accelarators for bicycles that [9] are formed, the moving bar [11] of the string of its auto acceleration device [6] penetrates lock ring [12], back-up ring [15], compression spring [16] is installed in the outer tube [17], moving bar [11] the top annulus [18] of string is fixed in the back clothes hanger, the lower end of outer tube [17] is fixed on the rear axle, the upper end is fixed with a watt seat [13], gear [20], a my body and function axle of sprocket wheel [21] is bearing on watt seat [13], gear [20] and tooth bar [19] engagement, sprocket wheel [21] links with acceleration flywheel [7] by quickening chain [10], realize chain-driving, the upper end of tooth bar [19] links with the moving bar [11] of string, the lower end penetrates the side's cover [22] that is fixed on outer tube [17] bottom, and in square cover [22], slide, the both sides of bicycle rear rack all are equipped with auto acceleration device [6], quickening flywheel [7] is by flywheel 1, flywheel 2 and flywheel 3 constitute, when downward compression spring [16], tooth bar [19] drives the gear [20] on the left side, sprocket wheel [21], by quickening chain [10], make the flywheel 1 that quickens flywheel [7] to front haulage; When compression spring [16] rebounded, tooth bar [19] drove gear [20], the sprocket wheel [21] on the right, by quickening chain [10], made the flywheel 2 that quickens flywheel [7] to front haulage.
