Abstract
The utility model discloses a power -saving high -speed bicycle, this bicycle include frame (1), front wheel (2) and rear wheel (3), and install respectively in the front and back end of frame (1) front wheel (2) and rear wheel (3), still installs improved generation transmission on the frame, improved generation transmission include internal gear (4), small faceplate (5), pinion (6), flywheel (7) and chain (8), internal gear (4) and step (9) coaxial arrangement are on frame (1), small faceplate (5), pinion (6) coaxial arrangement is in later half round below of internal gear (4), pinion (6) meshing internal gear (4), coaxial arrangement flywheel (7) are gone up in rear wheel (3), twine on flywheel (7) and small faceplate (5) chain (8). The utility model discloses a let internal gear radius grow, pinion radius diminish among the transmission to let the small faceplate rotational speed become fast, according to shaft lever principle, make the laborsaving high speed of bicycle.
Description
Technical field
The utility model relates to bicycle, is specifically related to a kind of Labor-saving high-speed bicycle.
Background technology
Ordinary bicycle is with foot-operated floral disc, by chain gear to flywheel, belongs to wheel shaft lever motion, but less owing to taking turns with axle radii ratio, and labor-saving effect is still not ideal enough; In addition faceplate diameter is comparatively large, and flywheel diameter is less, and driving chain and horizon angle are comparatively large, have decomposed the power of transmission, still can feel effort when riding.
Summary of the invention
The purpose of this utility model is: provide a kind of Labor-saving high-speed bicycle, improved transmission device installed by vehicle frame, makes to ride laborsaving, improves the speed of a motor vehicle, promotes the use of and reach energy-conserving and environment-protective.
Technical solution of the present utility model is: this bicycle comprises vehicle frame, front-wheel and trailing wheel, front-wheel and trailing wheel are arranged on the front and back end of vehicle frame respectively, it is characterized in that: vehicle frame also installs improved transmission device, described improved transmission device comprises inner gear, small faceplate, miniature gears, flywheel and chain, inner gear and step are coaxially arranged on vehicle frame, small faceplate, miniature gears are coaxially arranged on the later half below of taking turns of inner gear, miniature gears engagement inner gear, on trailing wheel, coaxial Flywheel, flywheel and small faceplate are wound around chain.
Wherein, the diameter of inner gear is 210mm, and the diameter of miniature gears is 70mm, and their diameter is than being 3:1, and revolution ratio is 1:3; Small faceplate diameter is 1.5 times of flywheel diameter, and the revolution ratio of inner gear and flywheel is 1:4.5.
When riding, drive inner gear by step, drive miniature gears by inner gear, then drive small faceplate by miniature gears, finally rotated by small faceplate flywheel driven.
The utility model has the following advantages:
1, by adding the radius of the reduced radius miniature gears of inner gear, the revolution ratio of inner gear and miniature gears is increased, because miniature gears installation site is in the later half below of taking turns of inner gear, have an effect when riding position be first half wheel, the arm of at this moment step is in state farthest from miniature gears, according to the lever principle of wheel shaft, bicycle labor saving at a high speed.
2, inner gear diameter is 210mm, and miniature gears diameter is 70mm, and their diameter is than being 3:1, and revolution ratio is 1:3, according to the lever principle of wheel shaft, and by bike laborsaving 2/3rds.
3, small faceplate is mounted on miniature gears, and the diameter of small faceplate is 1.5 times of flywheel diameter, thus the revolution ratio of inner gear and flywheel is 1:4.5, improves riding speed.
4, this improved transmission device also can be used for transformation or the manufacture of pedal three-wheel or four-wheeled.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
In figure: 1 vehicle frame, 2 front-wheels, 3 trailing wheels, 4 inner geares, 5 small faceplates, 6 miniature gearss, 7 flywheels, 8 chains, 9 steps.
Detailed description of the invention
As shown in Figure 1, this bicycle comprises vehicle frame 1, front-wheel 2 and trailing wheel 3, front-wheel 2 and trailing wheel 3 are arranged on the front and back end of vehicle frame 1 respectively, it is characterized in that: vehicle frame also installs improved transmission device, described improved transmission device comprises inner gear 4, small faceplate 5, miniature gears 6, flywheel 7 and chain 8, inner gear 4 and step 9 are coaxially arranged on vehicle frame 1, small faceplate 5, miniature gears 6 are coaxially arranged on the later half below of taking turns of inner gear 4, miniature gears 6 engages inner gear 4, on trailing wheel 3, coaxial Flywheel 7, flywheel 7 and small faceplate 5 are wound around chain 8.
Wherein, the diameter of inner gear 4 is 210mm, and the diameter of miniature gears 6 is 70mm, and their diameter is than being 3:1, and revolution ratio is 1:3; Small faceplate 5 diameter is 1.5 times of flywheel 7 diameter, and the revolution ratio of inner gear and flywheel is 1:4.5.
When riding, drive inner gear 4 by step 9, drive miniature gears 6 by inner gear 4, then drive small faceplate 5 by miniature gears 6, finally rotated by small faceplate 5 flywheel driven 7.
