Abstract
The utility model relates to the speed increasing actuating mechanism of a bicycle, comprising a wheel disc, chains and two flywheels. The two flywheels are installed on the two ends of the rear wheel shaft of the bicycle respectively; one flywheel is connected with a sprocket wheel via a chain, the other flywheel which is coaxial with the sprocket wheel is installed in the middle position of the sprocket shaft and connected with the wheel disc via another chain. According to the principle that the small part is driven by the big part in the mechanical transmission and the principle of reacceleration, the utility model improves the running speed of the bicycle, saves the physical strength if the rider, and provides convenience to the travel of people.
Description
Technical field the utility model relates to a kind of Poewr transmission mechanism of rickshaw, particularly the bicycle mechanism of driving up.
The background technology bicycle is one of people's main walking-replacing tool of going on a journey, it have easy to use, need not oil, advantage such as not power consumption, thereby very popular.Travelling of bicycle realizes by its transmission device.At present, the general-duty transmission mechanism of bicycle is made of wheel disc, chain and flywheel.Wheel disc and flywheel are contained in respectively on the axle of stretcher and trailing wheel, connect with chain between them.Handle stretcher, wheel disc is rotated, flywheel also and then rotates under the drive of chain, rotates thereby drive trailing wheel, and bicycle just can travel.Though this structure is simple, the power that transmits is limited, adopts the speed of bicycle running of this structure unhappy, and drives relatively effort.
Summary of the invention is at the defective and the deficiency of prior art, and the purpose of this utility model is to provide a kind of reasonable in design, quick, labour-saving bicycle mechanism of driving up.
The technical solution of the utility model is as follows: a kind of bicycle mechanism of driving up, comprise wheel disc, chain and flywheel, and described flywheel is two, is contained in the two ends of hind axle respectively; Flywheel links to each other with sprocket wheel by chain, is contained in the middle part of sprocket shaft with another flywheel of sprocket coaxiality, and it links to each other with wheel disc by another chain.
Beneficial effect: the utility model is with little and acceleration principle again according to mechanical drive is big, has improved the moving velocity of bicycle greatly, can save driver's muscle power better, for people's trip provides convenience.
Description of drawings is further described the utility model below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment as shown in drawings, a kind of bicycle mechanism of driving up comprises wheel disc, chain and flywheel, described flywheel 1 is two, is contained in the two ends of hind axle 2 respectively, the both sides that are distributed in trailing wheel 9 of symmetry; Flywheel 1 links to each other with sprocket wheel 4 by chain 3, is contained in the middle part of sprocket shaft 6 with coaxial another flywheel 5 of sprocket wheel 4, and it passes through chain 7 and links to each other with wheel disc 8; And wheel disc 8 is coaxial with stretcher 10; On the axle of described flywheel 5 and wheel disc 8 both sides detouchable bearing seat 11 is housed all.Be with little and acceleration principle again according to mechanical drive is big, the circumference of described wheel disc 8 is greater than the circumference of flywheel 5, and the circumference of sprocket wheel 4 is all bigger than the circumference of flywheel 5 and flywheel 1.
