Abstract
The utility model relates to a bicycle with an automatic accelerator; the automatic accelerator is connected with a back wheel of the bicycle through a back flat fork hinged with a center shaft; a flywheel and an energy storage spring are arranged on a wheel shaft of wheels; the energy storage spring can store energy because of the vibration of the bicycle when rid; the energy can help the bicycle advance; the utility model has automatic acceleration, power assisting buoyancy and comfort.
Description
The utility model belongs to a kind of bicycle.
Thereby existing bicycle advances by stepping road pin drive chain rotation driving car, not only effort is big in use, and the speed of a motor vehicle is slow, although people have done many-sided improvement on the transmission device of car, all fails to solve and not only can improve the speed of a motor vehicle but also can the labour-saving problem.In addition because the poor flexibility of car uses comfortable inadequately.
The purpose of this utility model is a kind of speed of a motor vehicle but also can be laborsaving and use comfortable bicycle of not only can having improved of design.
The utility model comprises vehicle frame, is connected with handlebar on it, and vehicle seat, wheel and axis also are installed, and car leg and chain wheel are installed on the axis, it is characterized in that being hinged with on the axis back chain stay, and the back wheels of vehicle of ining succession on the back chain stay is equipped with the flywheel with chain engages on the hind axle; Be connected with damper spring between wheel and the vehicle frame, also be connected with the driving device that the vibration by car can turn a wheel.
Damper spring and back damper spring before said damper spring comprises.Driving device and back driving device before driving device comprises, it is that the transfer of energy that produces owing to jolting in will car exercising is given energy stroage spring and is transferred on the wheel, thus the driving car advances.The utility model in use can make its normal enforcement by the step that steps car, helps car to advance thereby energy stroage spring is stored and release energy owing to jolting of car simultaneously, both can improve the speed of a motor vehicle, again can be laborsaving.Because back wheels of vehicle is not to be fixedly mounted on the vehicle frame, supports and go up, and be connected with damper spring between wheel and the vehicle frame, thereby make when using more flexible, more comfortable by the back chain stay that is hinged on axis.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Embodiment comprises vehicle frame (1) as shown in the figure, and vehicle seat (2) and handlebar are installed on it, also is connected with car front fork (6) and bicycle back fork (18).Damper spring (4) and back damper spring (29) also are connected with preceding portal frame (5) and back gantry (28) respectively, with a reinforcement effect before being connected respectively on car front fork (6) and the bicycle back fork (18).Car front-wheel (13) is installed on the car front fork (6), be connected with preceding driving device between car front-wheel (13) and the vehicle frame (1), should comprise the preceding flywheel (9) that is installed on the front wheel spindle (12) by preceding driving device, be connected with free-wheel clutch (11) between preceding flywheel (9) and the car front fork (6), be connected with energy stroage spring (10) between the inner ring of preceding flywheel (9) and the front wheel spindle (12); Be connected with a preceding line of pull (8) that preceding flywheel (9) is rotated on the preceding flywheel (9), should before an end of line of pull (a 8) branch being connected with retracing spring (7) and being fixed on car front fork (6) stick, the other end passes another branch that the pulley (3) that is installed in car front fork (6) top is fixed on car front fork (6) and sticks.Axis (14) is installed on the vehicle frame (1), car leg (16) and chain wheel (17) are installed on the axis (14), on the five-way (15) on the axis (14), be hinged with back chain stay (19), on back chain stay (19) and bicycle back fork (18), back wheels of vehicle (27) is installed, end at hind axle (23) is installed with and chain (20) ingear flywheel, be connected with the back driving device on the other end, this back driving device comprises the rear flywheel (26) that is positioned on the hind axle (23), be connected with free-wheel clutch (24) between rear flywheel (26) and the back chain stay (19), be connected with energy stroage spring (25) between the inner ring of rear flywheel (26) and the hind axle (23), be connected with the post-tensioning line of force (22) that rear flywheel (26) is rotated on the rear flywheel (26), one end of the post-tensioning line of force (22) is connected with retracing spring (21) and is fixed on the back chain stay (19), and the other end passes the pulley (30) that is installed in bicycle back fork (18) top and is fixed on the bicycle back fork (18).
Car is in driving process, because jolting of car handled preceding flywheel (9) and rear flywheel (26) acting respectively by the preceding line of pull (8) and the post-tensioning line of force (22), energy stroage spring (10) (25) is screwed with stored energy, and under the effect of free-wheel clutch (11) (24), loosen to release energy with axletree bonded assembly one end certainly respectively, thereby helping to drive car advances, use not only comfortable but also briskly, for more sturdy and durable, the tire of this bicycle uses solid tyre.
