Abstract
A bicycle booster belongs to a bicycle booster. The booster is provided with a box body, an input flywheel and an output flywheel are respectively arranged at two ends of the box body, the input flywheel is connected with a long shaft, a power spring, a boosting sheet and a pinion are sequentially connected onto the long shaft, the output flywheel is connected with a short shaft, and a large gear is connected onto the short shaft. When the bicycle is used, when the pedal is pedaled in the forward direction, the bicycle runs normally, when the pedal is pedaled in the reverse direction, the power spring in the booster is energized under the action of the input flywheel, when the pedal is pedaled in the reverse direction, the power spring starts to release energy, the power spring and the power spring are positioned on the same shaft, the boosting sheet and the small gear rotate, the rotating small gear is meshed with the large gear, kinetic energy is output through the output flywheel, the output flywheel drives the large chain wheel, namely the bicycle wheel to rotate, and when the bicycle is ridden for a long time, a rider can be helped to move the bicycle and rest at intervals of the rider.
Description
Technical field the utility model relates to a kind of servo-unit, particularly a kind of Accelarators for bicycles.
Background technology
At present, the bicycle power driven that people use has a gear wheel, and gear wheel is connected with stretcher, is connected with flywheel on the trailing wheel of bicycle, is connected with chain between flywheel and gear wheel.During use, the rider pedals stretcher, gear wheel drives flywheel by chain, thereby bicycle rear is rotated, and the power that bicycle advances relies on cyclist's applied force fully, when riding for a long time, the cyclist can not get having a rest, and physical demands is big, and the people is felt tired.
Summary of the invention
The purpose of this utility model is will provide a kind of to ride during bicycle the Accelarators for bicycles that can help cyclist's aiding bicycle and can make the cyclist gap obtain having a rest for a long time.
The purpose of this utility model is achieved in that this servo-unit has a casing, two ends at casing have input flywheel and output flywheel respectively, the input flywheel is connected with major axis, be connected with power clockwork spring, power-assisted sheet and miniature gears on the major axis in turn, the output flywheel is connected with minor axis, is connected with big gear wheel on the minor axis.
Major axis and minor axis are connected on the casing by bearing, and miniature gears and big gear wheel are meshing with each other.
Beneficial effect: owing to adopt such scheme, during use, the input flywheel of this servo-unit is installed between gear wheel and the flywheel, the midway location of the chain that is positioned at, during chain movement, this input flywheel is followed running, a large toothed disk is installed on the trailing wheel of bicycle, the output flywheel of this servo-unit is connected with large toothed disk by chain, when forward stepped stretcher, the bicycle cruising was when oppositely stepping stretcher, under the effect of input flywheel, give in the servo-unit the power clockwork spring energetically, when stopping oppositely stepping stretcher, the power clockwork spring begins to release energy, and is in a power-assisted sheet and a pinion rotation on the major axis together with the power clockwork spring, the miniature gears and the big gear wheel of rotating are meshing with each other, by the output of output flywheel, it is that bicycle quick rotates that the output flywheel drives large toothed disk, when riding bicycle for a long time with kinetic energy, can help cyclist's aiding bicycle and can make the cyclist gap obtain having a rest, reach the purpose of this utility model.This servo-unit is simple in structure, and is easy for installation, when riding bicycle for a long time, can help cyclist's aiding bicycle and can make the cyclist gap obtain having a rest.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
Embodiment 1: this servo-unit has a casing 8, two ends at casing 8 have input flywheel 3 and output flywheel 13 respectively, input flywheel 3 is connected with major axis 9, be connected with power clockwork spring 6, power-assisted sheet 7 and miniature gears 10 on the major axis 9 in turn, output flywheel 13 is connected with minor axis 12, is connected with big gear wheel 11 on the minor axis 12.The input flywheel 3 of this servo-unit is installed between gear wheel 1 and the flywheel 4, and the midway location of the chain 2 that is positioned at is connected with stretcher 5 on the gear wheel 1, and a large toothed disk 14 is installed on the trailing wheel of bicycle, and output flywheel 13 is connected with large toothed disk 14 by chain.
Major axis 9 and minor axis 12 are connected on the casing 8 by bearing, and miniature gears 10 is meshing with each other with big gear wheel 11.
