Abstract
The utility model relates to a foldable bicycle with a secondary transmission mechanism; a transmission mechanism is composed of two small chain wheels, two chains, a large chain plate, a fly wheel, etc. the two small chain wheels are engaged with each other and are positioned by a fork type shaft pin; a transmission mechanism which is formed by the large chain plate, one of the small chain wheels and the chains can be fixed on a hinging device on a bicycle frame to rotate 180 DEG; the utility model solves the problem that bicycles are difficult to fold because the position of the transmission mechanism is fixed and the chains are too long.
Description
The utility model relates to the bicycle of collapsible secondary transmission device.
People are big for solving the bicycle volume, not portable and problem such as park, various Foldable bicycles have been designed, but because the portion of chain of transmission mechanism of bicycle, there are many unsurmountable problems folding up, various folding modes is all as easy as rolling off a log to cause coming off of transmission mechanism of bicycle chain, has brought inconvenience for people's use.
The purpose of this utility model is to provide a kind of bicycle of collapsible secondary transmission device, and two transmission devices are foldable integral easily.
To achieve these goals, the utility model is achieved through the following technical solutions, the bicycle of collapsible secondary transmission device, it is made up of vehicle frame, wheel, handlebar, foot-operated, big chain plate, chain, flywheel etc., transmission minor sprocket and the interlock each other of secondary transmission minor sprocket, two minor sprockets are by V shape pivot pin location.One time the transmission minor sprocket is fixed on the vehicle frame by support, and it constitutes transmission device with big chain plate and chain, and secondary transmission minor sprocket is fixed on the pole by support.It constitutes transmission device with flywheel and chain.
Owing to adopted above technical scheme, the transmission mechanism of bicycle of can making over is difficult for folding problem, can make bicycle more convenient folding under the situation that shortens transmission mechanism of bicycle.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of two minor sprockets of the utility model.
See Fig. 1, Fig. 2.
The bicycle of collapsible secondary transmission device, it is by vehicle frame 1, wheel 8, big chain plate 9, flywheel 7 and minor sprocket 3,11 formations such as grade, minor sprocket 3 is fixed on the pole 5 by support 4, one end of pole 5 is fixed on the axle of flywheel 7, the other end is provided with articulated mounting 2 and is fixed on the vehicle frame 1, minor sprocket 11 is fixed on the vehicle frame 1 by support 8, big chain plate 9 is located on the vehicle frame 1, two minor sprockets 3,11 interlocks are each other also passed through a V shape pivot pin 6 location, big chain plate 9 and minor sprocket 11 connect and compose transmission device by chain, minor sprocket 3 and flywheel 7 connect and compose transmission device by chain, when normally riding, two minor sprockets 3,11 interlocks each other, synchronization action, when big chain plate 9 drove minor sprocket 11 by chain, minor sprocket 3 drove flywheel 7 runnings by chain.When folding, unclamp V shape pivot pin 10 between two minor sprockets 3,11, can be with big chain plate 9 and minor sprocket 11 integral body by being fixed on 180 ° of rotations in articulated mounting 2 places on the support 1, folding fully.
