Abstract
The utility model discloses a novel electric bicycle anti-skidding flywheel comprising a shaft sleeve, a shaft bumper and a flywheel outer ring. The novel electric bicycle anti-skidding flywheel is characterized in that the flywheel further comprises set screws, the shaft sleeve extends downwards to form a fixing part and screw holes are formed in the fixing part. According to the novel electric bicycle anti-skidding flywheel, potential safety hazards of the electric bicycle, caused by the abrasion of fixed threads in an prior art are avoided, safety index is improved and potential traffic dangers are removed.
Description
Technical field
The utility model relates to a kind of for Electrical Bicycle auxiliary mechanism, relates in particular to the anti-skidding flywheel of a kind of new type electric bicycle.
Background technology
In recent years, the traffic jam phenomenon is day by day serious, and ordinarily resident's purchasing power level is limited, also fuel oil, environment and place etc. in many ways factor all restricting automobile and can not become in a short time popular walking-replacing tool, restriction has all been taked to self-propelled vehicle in many big cities.The fuel oil motor was once once becoming the vehicle that many cities are relatively popularized, but because the impact of the factors such as safety traffic and environmental protection is popularized the formation hindering factor to it.And Electrical Bicycle combines the advantage of motor bike and bicycle, low with its expense, stop convenient, not affected with by traffic jam and price is comparatively cheap etc. that comprehensive advantage is accepted by increasing working clan, student family, become a kind of desirable " green " walking-replacing tool, solve beyond doubt the important development direction of the daily traffic of town dweller.Simultaneously, environment and quality of life that present people's pay attention to day by day is depended on for existence, each big city proposes to improve air standards, reduces quantity discharged and reduces the measures such as aerial contamination, and free of contamination Electrical Bicycle becomes the main solution of environmentalist's promotion.
Along with the urgent pursuit of human society to energy savings and environmental protection, traditional fuel vehicle is just experiencing the process that changes to the new forms of energy car.Develop first in China light-weight electric bicycle short decades from Tsing-Hua University, China has developed into the maximum Electrical Bicycle industry in the whole world.Thus, follow extensively popularizing of Electrical Bicycle, the safety performance of Electrical Bicycle also more and more receives user's concern.Electric bicycle flywheel is the critical component of Electrical Bicycle transmission, because it utilizes the M35*1 screw thread to be connected with the axle skin, and long-term the use, flywheel and the easy landing of axle skin bring greatly potential safety hazard to the customer.
The use electric bicycle flywheel of prior art, its concrete structure as shown in Figure 4, this electric bicycle flywheel structure has axle sleeve 402 on the surface of axle skin 401, these axle sleeve 402 sizes and axle skin 401 external diameters size corresponding matching, be provided with ball (not indicating among the figure) in detouchable axle bumper 403 and the flywheel outer ring 304, for guaranteeing that flywheel is connected with the safety of axle skin 401, prior art all adopts the M35*1 screw thread to link to each other with axle skin 401.
Yet, flywheel structure shown in Figure 4, after long-time the use, along with the wearing and tearing of screw thread, flywheel very easily comes off mutually with axle skin 401, so that there is greatly potential safety hazard in Electrical Bicycle.
The utility model content
Problem in view of above-mentioned prior art exists has proposed the utility model.
Therefore, the technical problems to be solved in the utility model is, electric bicycle flywheel is not come off at long-time rear flywheel and the axle skin of using, thereby avoids causing because of the wearing and tearing of retaining thread the potential safety hazard of Electrical Bicycle generation, eliminates potential traffic hazard.
In order to solve the problems of the technologies described above, the utility model has just proposed following technical scheme: the anti-skidding flywheel of a kind of new type electric bicycle, comprise axle sleeve, axle bumper and flywheel outer ring, and it also comprises holding screw, described axle sleeve extends to fixed part downwards, forms screw hole on the described fixed part.
As the anti-skidding flywheel of new type electric bicycle described in the utility model, a screw till the wherein said holding screw, its quantity is 1-4.
As the anti-skidding flywheel of new type electric bicycle described in the utility model, wherein said axle sleeve madial wall forms screw thread.
As the anti-skidding flywheel of new type electric bicycle described in the utility model, wherein said screw hole aperture is greater than holding screw nail footpath.
Adopted the anti-skidding flywheel of new type electric bicycle of structure described in the utility model, the utility model extends to form fixed part with former flywheel part axle sleeve, and offer screw hole at fixed part, by a screw that ends that matches with screw hole flywheel is fixed on the axle skin, thereby avoided causing because of the wearing and tearing of retaining thread in the prior art potential safety hazard of Electrical Bicycle generation, improve safety index, eliminated potential traffic hazard.
