Abstract
The utility model relates to a bicycle with a triangular frame. The main frame of the utility model is subtriangular. The utility model has the advantages of reasonable mechanical structure, high intensity, simple structure, less welding spots and low manufacturing cost; besides, the utility model can be ridden by men and women, production efficiency can be improved, and the consumption of materials required by the production of the utility model is small; steel saved by the utility model is considerable to China which has large consumption of bicycles.
Description
The utility model relates to a kind of three cantilevered corner beam bicycles.
In existing bicycle, vehicle frame generally all is by two quad type vehicle frames that triangle constituted, and exists solder joint many, the problem of poor stability.
The purpose of this utility model provides a kind of Stability Analysis of Structures, and solder joint is few, intensity is high,, bicycle that cost low few with material.
The purpose of this utility model realizes by following measure, by front-axle beam (4), front fork sleeve pipe (14), bottom girder (5), back vent (6), constitute approximate triangle frame, handlebar (1) is installed on front fork (2) top, front-wheel (3) is installed in the bottom, vehicle seat (12) is installed on front-axle beam (4) top, trailing wheel (7) and minor sprocket (8) are installed in back vent (6) bottom, axis (13) and hinge wheel (10) are installed in bottom girder (5) middle part, between hinge wheel (10) and minor sprocket (8), chain (9) is installed, axis (13) two ends are equipped with pedal crank (11), and front-wheel (3) is 1.5 to 2 to 3 with the diameter ratio of trailing wheel (7).
Narrate below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1 is an embodiment of the present utility model, and its structure as mentioned above.
Trailing wheel in this example (7) is adorned with 26 inches wheels, front-wheel (3) is adorned with 16 inches wheels, pedal crank (11) is liftoff unlikely too high like this, personnel can drive as present common car, preceding suitably dwindling of wheel diameter alleviated greatly to the front fork root shearing stress of rapid wear, and not influence aspect speed and brisk property.
These three cantilevered corner beam bicycle mechanical structures are reasonable, the intensity height, and simple in structure, solder joint is few, can enhance productivity, and few with material, cost is low, and concerning our bicycle big country, the steel of being saved are considerable.
