Abstract
A novel gearing for bicycles adds a transitional sprocket wheel (3) among a central axis tooth disc (1), a chain (2), and a flywheel (8) so that the chain (2) firstly drives the transitional sprocket wheel (3) and then drives a fly tooth (5) on the flywheel (8) through a chain (4) embedded in the inside groove of the transitional sprocket wheel (3). To guarantee the stable operation of the transitional sprocket wheel (3), steady bearings (6) and (7) are arranged on the interior circle of the sprocket wheel (3). The gearing device increases the bicycle speed, and is more stable for riding, more labor-saving, and easier for accelerating, and is a novel gearing for bicycles.
Description
Affiliated field
The utility model belongs to mechanical field, is specifically related to a kind of structure of bicycle new drive device.
Background technology
Bicycle in the market all adopts the axis chain wheel to rotate by the flywheel that chain drives on the rear wheel, realizes advancing of vehicle, and this transmission structures is simple, and is easy to maintenance, but that this driving device also exists riding speed is low, not enough labour-saving defective.
Technology contents
The purpose of this utility model is: design a kind of bicycle new drive device, it adopts multistage drive method, make ride more laborsaving, faster, low to overcome the speed that existing bicycle drive exists, the defective of the long-distance effort of riding.
The technical solution of the utility model is: be equipped with one and add large toothed disk on axis, chain drives a transition sprocket wheel that is positioned on the trailing wheel by chain wheel, this sprocket periphery outside is the tooth that matches with chain, the inner round side groove is embedded with one and encloses the chain that matches with flywheel teeth, for the stability that guarantees the transition sprocket wheel is equipped with backup bearing at its inner round side.
The axis chain wheel rotates and drives chain gear when riding, and chain makes the transition sprocket rotation that is positioned at trailing wheel, and the chain of transition sprocket wheel inboard drives flywheel again and rotates, and bicycle is travelled forward.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: chain, 5 flywheel teeth, 6,7 backup bearings, 8 flywheels in 1 axis chain wheel, 2 chains, 3 transition sprocket wheels, the 4 transition sprocket wheels
Implementation method
Axis is for strengthening shape chain wheel 1, tooth on chain 2 and the axis chain wheel 1 matches, chain 2 is inserted on the band tooth transition sprocket wheel 3 that coincide with it simultaneously, be embedded with a circle and flywheel teeth 5 chain 4 that matches at the inner round side groove of transition sprocket wheel 3, chain 4 is enclosed within on the flywheel teeth 5, flywheel 8 is positioned on the bicycle rear shaft, operates steadily for guaranteeing transition sprocket wheel 3, at sprocket wheel 3 inner round side backup bearing 6,7 is installed.
When rotating, axis chain wheel 1 drives chain 2, chain 2 drives the transition sprocket wheel 3 that is positioned at trailing wheel, when transition sprocket wheel 3 rotates, the flywheel teeth that chain 4 in its inside circumference groove drives on the flywheel 8 is rotated, thereby trailing wheel is rotated, for guaranteeing that transition sprocket wheel 3 operates steadily, and is equipped with backup bearing 6,7 within it on the side circumference.
The utility model is ridden steadily, and is laborsaving quick, quicken easily, and be the another new construction of present bicycle drive.
Claims (3)
1, a kind of bicycle new drive device is made up of axis chain wheel (1) and chain (2), flywheel (8), it is characterized in that: on the flywheel teeth (5) of flywheel (8) transition sprocket wheel (3) is housed.
2, a kind of bicycle new drive device according to claim 1 is characterized in that: the circle outside of transition sprocket wheel (3) is the tooth that matches with chain (2), and its inner round side groove is embedded with one and encloses the interior chain (4) that matches with flywheel teeth (5).
