Abstract
The utility model discloses a bicycle transmission mechanism, which consists of a face chuck and a flywheel. The utility model is characterized in that a transmission shaft rotates and matches in the seat hole of the shaft on the back fork of the bicycle. The cylindrical teeth on the two ends mesh with the end surface teeth of the face chuck and the flywheel respectively. The transmission mechanism adopts the gear transmission, thus having the advantage of small transmission contact area, less power consumption and laborsaving by comparing with the existing chain transmission mechanism.
Description
Technical field:
The utility model relates to the transmission device of a kind of vehicle, particularly a kind of bicycle.
Background technology:
Existing transmission mechanism of bicycle is a chain-driving, this chain drive, because chain is meshed with the nearly half of change dish and flywheel, the gearing friction area is big, and consumed energy is many, and the process of riding is prone to the shortcoming of chain.
Summary of the invention:
The utility model technical issues that need to address are little, the labour-saving transmission devices of a kind of gearing friction area of design.The technical solution of the utility model is, a kind of transmission device of bicycle, and it comprises floral disc and flywheel, it is characterized in that: in the axle bed hole of transmission shaft normal-running fit on back fork of bicycle, the cylinder tooth at its two ends is meshed with the end face tooth of floral disc and flywheel respectively.The utility model is owing to change the tooth on existing flywheel and the floral disc circumference into the end face tooth, on bicycle back fork, be provided with a transmission shaft, its two ends respectively have a cylinder tooth to be meshed with the end face tooth of floral disc and flywheel respectively, its ingear number of teeth is few, thereby the utility model to have frictional area compared with the prior art little, save the advantage of muscle power.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1. floral disc 2. axle beds 3. transmission shafts 4. gears 5. end face teeth 6. flywheels.
The specific embodiment:
The transmission device of bicycle of the present utility model comprises that two ends are provided with the transmission shaft 3 of gear 4, in two axle bed 2 holes of this transmission shaft normal-running fit on back fork of bicycle, also bearing can be set between transmission shaft and the axle bed hole, reduces gearing friction.The gear at transmission shaft two ends is meshed with the end face tooth 5 of floral disc 1 and flywheel 6 respectively, and 6 on floral disc 1 and flywheel are provided with end face tooth 5, and no longer establish all teeth.The number of teeth of the gear at floral disc, flywheel and transmission shaft two ends can be determined according to desired transmission speed ratio.This meshed transmission gear is littler than the area of contact that chain passes transmission, thereby consumption of power is few, has the labour-saving advantage.
