Abstract
The utility model discloses a chain tensioning device of a damping simple electric bicycle. The chain tensioning device comprises a cantilever arm seat, a cantilever arm, a torsion spring and a riding wheel, wherein the cantilever arm seat is hinged with one end of the cantilever arm while the other end of the cantilever arm is hinged with the riding wheel, the torsion spring is mounted at a hinged joint of the cantilever arm seat and the cantilever arm, and one end of the torsion spring is fixedly connected with the cantilever arm seat while the other end of the torsion spring is fixedly connected with a middle section of the cantilever arm. Pressure of the torsion spring onto the cantilever arm is transmitted to the chain through the riding wheel at the front end of the cantilever arm, thereby keeping proper tensioning degree of the chain and preventing the chain from being falling off due to shock. Simultaneously, the chain tensioning device can be used for adjusting chain tightness degree which changes due to length of the chain, and is simple in structure and obvious in effect.
Description
[technical field]
The utility model relates to the sulky vehicle of chain gear, relates in particular to a kind of chain swelling device of shock-absorbing type simple electric car.
[background technology]
Known shock-absorbing type simple electric car is running into when jolting, and is either large or small because of the flexible width between centers of sprocket wheel and flywheel that causes of bumper also changes thereupon, can cause the driving chain disconnection when this width between centers is excessive, can fall the chain phenomenon when too small.For solving this deficiency, some vehicle is purchased and has been used the chain device of dialling on the variable speed bicycle to be contained on the rear axle, make chain keep appropriate tensioner degree, but it takes up room greatly price more expensive (because of the brand difference, its cost is about 20-80 unit).
China Patent No. ZL200620068617.8 has announced a kind of chain automatic regulator, it is to increase a montant and lever and extension spring and runner on under-carriage, under the pulling force of extension spring, make runner all the time with the chain tension, thereby reach the purpose of automatically regulating chain length.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of chain swelling device that can keep the chain appropriateness tensioner degree of shock-absorbing type battery-driven car.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of chain swelling device of shock-absorbing type Electrical Bicycle, comprise choose arm seat, choose arm, torque spring and support roller, it is hinged with the rear end of choosing arm to choose arm seat, and front end and the support roller of choosing arm are hinged; Torque spring is contained in the hinged part of choosing arm seat and choosing the arm rear end, and an end of torque spring is with to choose arm seat affixed, and the other end is with to choose the arm stage casing affixed.
More perfect is, comprise shoulder bolt and stable cover, choosing arm seat is U-shaped, have bolt hole in the vertical plates on both sides corresponding section of choosing arm seat, torque spring is enclosed within the outside of stable cover, shoulder bolt penetrates the centre hole of the bolt hole of choosing arm seat one cant board, stable cover successively and chooses the through hole of arm rear end, and the threaded portion of shoulder bolt is spirally connected with the opposite side riser of choosing arm seat, and choosing arm is that rotate at the center with the shoulder bolt.
More perfect is to stablize the end face of cover and choose the side of arm rear end by being welded to connect.
More perfect is, comprises shoulder bolt, and the support roller center shaft is perpendicular to crossing the vertical plane surface of choosing the arm axle line, and shoulder bolt passes the support roller centre hole and is connected with the screw of choosing the arm front end.
More perfect is that support roller is the flute profile support roller, indent in the middle of the outer surface, edge projection.
More perfect is that support roller is a nylon material.
The beneficial effects of the utility model are, utilize torque spring to choosing the pressure of arm, pass to chain by the support roller of choosing the arm front end, make chain total energy keep suitable tensioner degree and be difficult for rolling and shake off chain, also can suitably regulate simultaneously the chain tightness that the length variations because of chain causes, it is simple in structure, and effect is obvious.
