Abstract
A transmission mechanism used for a portable folding bicycle comprises a wheel disk, an exceeding type flywheel and a transmission belt, wherein the exceeding type flywheel is composed of an inner wheel, an outer wheel, a pawl and a torsion spring. The transmission mechanism is characterized in that the transmission belt is composed of a plurality of horizontal rings and vertical rings and connected in series by a way of a horizontal ring to a vertical ring to a horizontal ring, outer radial surfaces of the wheel disk and the outer wheel are provided with ring-shaped grooves, inner walls of two ring-shaped groove walls are symmetrically provided with slots which form an embedding slot, the horizontal ring is matched with the embedding slot, and the vertical ring is matched with the ring-shaped groove. With the structure, the transmission belt is connected in series by the horizontal rings and the vertical rings in the way of a horizontal ring to a vertical ring to a horizontal ring so as to use the transmission belt to be freely bent. The utility model overcomes the shortage that a chain can only warp around a shaft but not bend in the prior art, thereby effectively overcoming the shortage in the prior art so as to cause a rear fork mounting to conveniently rotate on a horizontal surface around a frame.
Description
Technical field
The utility model relates to a kind of portable folding bicycle, especially a kind of transmission device of portable folding bicycle.
Background technology
Present prior art, the transmission device that a kind of portable folding bicycle is used is by the flywheel and the chain of wheel disc, override type, and the flywheel of described override type is made of interior wheel disc, foreign steamer, ratchet and torsion spring.Existing problems are: use the folding bicycle of this transmission device, its rear crotch can not be around vehicle frame, rotate in horizontal surface.
Summary of the invention
The purpose of this utility model is: the transmission device that provides a kind of portable folding bicycle to use, it overcomes deficiency of the prior art effectively, can rear crotch be rotated in level around vehicle frame.
The utility model is achieved in that the transmission device that a kind of portable folding bicycle is used, it comprises the flywheel and the driving band of wheel disc, override type, the flywheel of described override type is made of interior wheel disc, foreign steamer, ratchet and torsion spring, its special character is: described driving band is made of some gimbal, vertical ring, according to " form of gimbal, vertical ring, gimbal is serially connected; On the radially-outer surface of described wheel disc, foreign steamer annular groove is arranged, on two inwalls of annular groove symmetrically arranged groove is arranged, two grooves constitute the embedded groove of gimbal, are uniform-distribution with several embedded grooves on the annular groove, gimbal cooperates with embedded groove, and vertical ring cooperates with annular groove.
The transmission device that a kind of portable folding bicycle is used, its special character is: described gimbal, vertical ring are " runway shape "; Groove is " half runway shape ", and embedded groove is " runway shape ".
The transmission device that a kind of portable folding bicycle is used, its special character is: described gimbal, vertical ring are " annular arrangement "; Groove is " arc ", and embedded groove is " circle ".
The transmission device that a kind of portable folding bicycle is used, it comprises the flywheel and the driving band of wheel disc, override type, the flywheel of described override type is made of interior wheel disc, foreign steamer, ratchet and torsion spring, its special character is: described wheel disc is that wheel disc, the foreign steamer of belt wheel tooth is the foreign steamer of belt wheel tooth, and described driving band is a synchronous cog belt.
The transmission device that a kind of portable folding bicycle of the utility model is used, described driving band is made of some gimbal, vertical ring, according to " form of gimbal, vertical ring, gimbal is serially connected; On the radially-outer surface of described wheel disc, foreign steamer annular groove is arranged, on two inwalls of annular groove symmetrically arranged groove is arranged, two grooves constitute the embedded groove of gimbal, are uniform-distribution with several embedded grooves on the annular groove, gimbal cooperates with embedded groove, and vertical ring cooperates with annular groove.Owing to adopt such structure, because driving band is by gimbal, vertical ring, according to " form of gimbal, vertical ring, gimbal is serially connected, and can make the driving band free bending.Overcome in the prior art chain and have only around axle and curl, defective that can not bending.So it overcomes deficiency of the prior art effectively, can rear crotch be rotated in level around vehicle frame.
