Abstract

The utility model relates to a galloping bicycle. The upper parts of a front fork and a rear fork of a bicycle body are hinged; a front wheel and a rear wheel are respectively arranged at the lower end of the front fork and the lower end of the rear fork; a front barrel wing and a rear barrel wing are respectively arranged at the middle part of the front fork and the middle part of the rear fork; a seat is arranged on the upper part of the front fork; the lower end of the front fork consists of a front shaft, an outer bearing, a middle shaft, a planetary gear frame, a central needle wheel, a fixed needle wheel, a planetary gear, a unidirectional clutch and a crank pedal which are connected and matched with one another; a transmission device protection cover is fixed outside the planetary gear frame; and handles are fixed at the upper end of the rear fork.

Description

Driving voluntarily

One, technical field

The utility model belongs to the technological improvement of traffic appliance, is specifically related to a kind of driving voluntarily.

Two, background technology

Bicycle is a kind of simple, vehicle of being prone to capable, common, convenient, economy, environmental protection.Though it is regenerated through nearly innovation of going up a century, sees totally to differ from one another that its in-use performance is unsatisfactory.

Three, summary of the invention

The purpose of the utility model is in order to overcome the deficiency of existing bicycle structure, provide a kind of laborsaving, at a high speed, efficiently with the driving voluntarily of designs simplification, the main technical schemes of its solution is by front and back wheel, the front and back tube wing, front and rear fork, handlebar, vehicle seat, ride, driving device connects to form mutually; Concrete structure is that the forward and backward portion of sticking with car body is that hinge connects, and front and back wheel respectively is equipped with in the front and rear fork lower end, the tube wing before and after respectively be equipped with at the middle part; Vehicle seat is equipped with on the top of front fork, and the driving device that be equipped with the front fork lower end is through front axle; Outer bearing, neck bearing, axis; Planetary gear carrier, center pinwheel, fixedly pinwheel; Planetary wheel, free-wheel clutch, crank is foot-operated to be connected mutually and the cooperation composition; The planetary gear carrier fixed outside the driving device protective cover, and handlebar is being fixed in the upper end of back vent, and the planetary gear carrier fixed outside the driving device protective cover.

The utility model is rational in infrastructure, and is simple to operate, compare with the chain-driving bicycle of conventional confguration have more laborsaving, more fast, more efficiently, advantage more easily.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model embodiment is elaborated.

Fig. 1 is the integral structure scheme drawing of the utility model.

Fig. 2 is the generalized section of the utility model driving device.

Fig. 3 is the structural representation of the utility model train.

1. front-wheels, the 2. placket wings, 3. front forks, 4. handlebars, 5. vehicle seats, 6. a back wing, 7. back vents, 8. trailing wheels 9. are ridden fixedly pinwheel 19. planetary wheels 20. free-wheel clutchs of 10. cranks, 11. drivings device, 12. front axles, 13. outer bearings, 14. neck bearings, 15. axis, 16. planetary gear carriers, 17. center pinwheels 18. among the figure

Five, the specific embodiment

By a kind of driving voluntarily shown in Fig. 1-3, its keystone configuration is that the forward and backward portion of sticking with car body is that hinge connects, and front and back wheel (1), (8) respectively are equipped with in the front and rear fork lower end, the tube wing (2), (6) before and after respectively be equipped with at the middle part; Vehicle seat (5) is equipped with on the top of front fork (3), the driving device that be equipped with the front fork lower end, and through front axle (12), outer bearing (13); Neck bearing (14), axis (15), planetary gear carrier (16), center pinwheel (17); Fixing pinwheel (18), planetary wheel (19), free-wheel clutch (20), crank (10); Foot-operated (9) connect and cooperate composition mutually, and the planetary gear carrier fixed outside driving device (11) protective cover, and handlebar (4) is being fixed in the upper end of back vent (7).

During use, step on the car body that moving and just can move ahead as long as put on foot-operated.When carrying on the pin, foot-operated (9) that are enclosed within on the pin are also and then up, and crank this moment (10) rotates around axis (15), and free-wheel clutch (20) is reverse to break away from, and axis is motionless.When pedaling under the foot-operated quilt, free-wheel clutch (20) self-locking, power is passed to axis (15); It is clockwise rotated, when axis clockwise rotates, drive planetary gear carrier (16) and star gear (19) and rotate together; When planetary wheel is prolonging fixedly pinwheel (18) rotation; Drive center pinwheel (17) clickwise drives front axle (12) rotation again after the rotation of center pinwheel, front axle rotation back drive front-wheel (1) rolls and moves ahead; As long as rider's bipod ceaselessly up-and-down movement, driving just can continue to move ahead voluntarily.Because the effect of the front and back tube wing, when the speed of a motor vehicle was accelerated, the trailing wheel of car body (8) just can be lifted from ground, had increased the propulsive effort and the power-assist power of driving voluntarily, and it is flexible, laborsaving efficient that it is turned to.

Claims
