Abstract
The utility model discloses a tandem bicycle suitable for two people to ride, which primarily comprises a front and a rear wheel (16, 10), a W-shaped frame (4), a front fork (1), a brake (2), a front and a rear handle bar (3, 6), a front and a rear seat (5,7), a front and rear pedal (11,22), a bracket (8), a front intermediate axle (14), a middle axle (12), a rear axle (9), a chain (13) and a saw disc (15). The utility model is characterized in that the W-shaped frame (4) is movably connected with the rear handle bar (6), the super-clutch saw disc (15) is connected to the axle roller of the front intermediate axle (14) and the middle axle (12), the super-clutch saw disc is formed by a flywheel (17) that is fixedly connected to a transmission chain wheel (21) through a bolt (18), an outer jacket of the chain wheel (19) is movably connected with an eccentric jacket (20). The utility model has simple structure and is flexible to ride, which can be independently operated by the front rider or by the rear rider with the other one keep stationery; therefore, the bicycle is more convenient, free and relax for the rider to ride.
Description
Technical field
The utility model belongs to the vehicle, is specifically related to be fit to double tandem bicycle of riding.
Background technology
At present, bicycle mostly is single rider, on the tandem bicycle market as amusement and recreation sale is arranged also, but demand is little, and this mainly is because some shortcoming of tandem bicycle is restricting: 1, the tandem bicycle structure is not compact, and is dumb in the process of riding; 2, first people is the active bicyclist, and second people locates driven status, and bicycle can not advance when the former does not ride, and the former rides, and when the latter did not ride, though vehicle travels in the same old way, the latter's both feet will be followed foot-operated the rotation passively; Light when 3, the latter locates subordinate status and do not have by bike freely felt.
Technology contents
The purpose of this utility model is: design a kind of tandem bicycle, adopt the overdrive clutch member, both can the driven vehicle before and after making, and the opposing party can keep quiet relatively moving state during side driving, allows the person of riding that freedom is more arranged.
Technical solution of the present utility model is: this tandem bicycle mainly includes parts such as front and back wheel, W type vehicle frame, front fork, brake, front and back handlebar, seat, front and back, front and back are foot-operated, support, preceding axis, axis, rear axle, chain wheel, be characterized in, flexibly connect rear bar on the W type vehicle frame, connect overdrive clutch chain wheel parts on the beaming roller of preceding axis, axis, described overdrive clutch chain wheel parts are connected on the speed-changing chain through bolt by flywheel and constitute, and eccentric bushing puts outside screw flexibly connects sprocket wheel.
