Description
Technical field
The utility model relates to a kind of crank of bicycle, particularly relates to a kind of wheeled bicycle crank.
Background technology
At present, the crank of bicycle all is to adopt traditional crank type crank, and its work done point is concentrated relatively, work done face is little, and when the crank of a side forwarded the operation point to, the cyclist approximately had only 1/3rd to be used in the work done for its reinforcing, 2/3rds power is in the passive idle running, thereby relatively requires great effort.In addition, the crank type crank is also hung cyclist's trouser legs, very inconvenience through regular meeting.Moreover its form is also more single, and outward appearance does not have characteristics.
Summary of the invention
In order to overcome the weak point of existing bicycle crank, the utility model provides a kind of wheeled bicycle crank.
The technical solution of the utility model is achieved in that a kind of wheeled bicycle crank, and it is provided with chain wheel and stretcher.This wheeled crank has an outer ring, and the outer ring is provided with a stretcher connecting bushing and connects a stretcher; Described outer ring is provided with disc (connection gusset), and disc is connected on the bottom bracket axle; Described bottom bracket axle is provided with chain wheel.Also be provided with a trim board on this wheeled crank, trim board is fixed by the lock spiral shell that connects bicycle middle shaft.
This wheeled crank is installed on the axis of bicycle and uses, and on the wheeled crank of opposite side chain wheel is not set.
The design of this wheeled crank meets mechanics principle, the actual proof of using, and under the effect of equal power, its work done face is big, and speed-raising is fast, and is laborsaving.
Usefulness of the present utility model is: (1) is rational in infrastructure, outward appearance novelty, attractive in appearance.(2) work done face is big, and speed-raising is fast, and is laborsaving.(3) overcome the defective that the crank axis is hung trouser legs.
