Abstract

A three-wheel bicycle includes a beam, a middle shaft sleeve, a chain wheel and a fly wheel. The utility model is characterized in that the rear part of the beam is provided with two rear wheels; the fly wheel is arranged between the two rear wheels and is fixedly connected with the two rear wheels. The special design of double rear wheels enhances the stability of the utility model and leads the utility model to be capable of standing on site which is suitable for the crowed area of a city in particular; the stability is extremely good when the three-wheel bicycle is rided slowly, thus being free of going off and supporting the ground with a foot when the bicycle is stopped for a while. A learner can ride the three-wheel bicycle only by a short period of time, thus saving the procedure of 'falling off' when learning the bicycle. The double-wheel structure also enhances the loading capacity of the utility model, can ride even if one rear wheel is flat, thus being convenient for the use of the learner.

Description

Tricycle

Technical field:

The utility model relates to a kind of foot-operated or Electrical Bicycle.

Background technology:

At present, generally the bicycle of Shi Yonging is the two-wheel structure, this car comprises a front-wheel and a trailing wheel, front and rear wheel links to each other with front fork by the car beam, the car beam is arranged with bottom bracket axle, in the bottom bracket axle is axis, and axis is provided with sprocket wheel and pedal, between the flywheel on sprocket wheel and the rear wheel hub chain is arranged.Poor stability when this cycling speed is slow especially for the beginner, without repeatedly " wrestling ", is to be difficult to association by bike; Simultaneously, this bicycle is the back puncture in a single day, and car just can't be ridden, and make troubles to the cyclist, and cycle tyre is punctured, and often all is the back tire.

Summary of the invention:

The purpose of this utility model is a kind of good stability of design, still rideable tricycle behind the puncture after.

The realization the technical solution of the utility model is, a kind of tricycle comprises car beam, bottom bracket axle, sprocket wheel and flywheel, it is characterized in that, described Che Liang rear portion is provided with two trailing wheels, flywheel be arranged between two trailing wheels and and two trailing wheels affixed.

The unique design of double rear wheel strengthens the utility model stability, can stand in the original place, adapts to the urban human location that blocks up especially more, and when riding at a slow speed, stability is special good, during of short duration parking, need not get off, without heel brace ground, just can realize; The beginner only needs the short time exercise just can learn to ride, and learns car and again need not pass through " wrestling " this program.The double rear wheel structure also makes load-carrying capacity of the present utility model strengthen, and a trailing wheel does not have gas, can ride in the same old way, has made things convenient for user's use.

Description of drawings:

Fig. 1 is a perspective view of the present utility model.

Fig. 2 is the structural representation of the utility model double rear wheel.

Fig. 3 is the structural representation that the utility model car beam bottom connects bottom bracket axle, sprocket part.

Number in the figure: 1 car beam, 2 trailing wheels, 3 flywheels, 4 fall " Y " 5 left bottom bracket axles, 6 sprocket wheels, 7 right bottom bracket axles, 8 axis.

The specific embodiment:

Referring to Fig. 1, Fig. 3, described car beam 1 bottom connects the position of bottom bracket axle for being " Y " 4 types that fall, described bottom bracket axle is set to left bottom bracket axle 5 and right bottom bracket axle 7, car beam 1 is " Y " 4 fork positions affixed left bottom bracket axle 5 of difference and right bottom bracket axles 7, and described sprocket wheel 6 is arranged between left bottom bracket axle 5 and the right bottom bracket axle 7 by axis 8.Referring to Fig. 2, described flywheel 3 is affixed respectively by thread connecting mode and two trailing wheels 2.

The utility model can be stepped on by manpower and step on the pedal that is arranged on the axis 8, drives sprocket wheel 6, drives trailing wheels 2 by flywheel 3, makes vehicle operating, storage battery and motor also can be set onboard drive sprocket wheel and drive.
