Description

The dry skating three-wheel vehicle in band compartment

Technical field

The utility model belongs to the bicycle field, especially a kind of dry skating three-wheel vehicle with the compartment.

Background technology

The transmission device of existing three-wheel vehicle generally is to be made of the drive sprocket on the axis, flywheel and driving chain on the rear axle, wherein power transmission is to drive drive sprocket by the pedal on the axis, drive sprocket is by the flywheel on the driving chain drive rear axle, and flywheel drives trailing wheel and rotates the promotion three-wheel vehicle to overtake.Though can improve riding speed by the transmission velocity ratio that increases drive sprocket and flywheel, when improving riding speed, can cause the effort of riding; Though and it is laborsaving when riding to reduce transmission velocity ratio, but can reduce the speed of riding.There are the following problems for two wheel constructions of the employing of existing three-wheel vehicle: (1) riding speed is difficult to improve and require great effort; (2) bicyclist of three-wheel vehicle is without any the windproof device that keeps off the rain, blowing and raining the time be the very painful thing of part by bike; (3) though existing three-wheel vehicle have take exercises, the function of goods consigned, amusement function is less.Therefore how can be not only laborsaving but also can improve moving velocity effectively by tricycle the time, simultaneously can for the bicyclist solve windproof problem of keeping off the rain and have certain recreational be that people needing to thirst for the problem that solves for many years

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of to make three-wheel vehicle can improve riding speed in riding laborsaving again, has amusement three-wheel vehicle function and also has the dry skating three-wheel vehicle in the band compartment of windproof rain-baffling device.

The utility model solves its technical matters and takes following technical scheme to realize:

The dry skating three-wheel vehicle in this band compartment, by tricycle frame, two front-wheels, trailing wheel constitutes, it is characterized in that: tricycle frame is packed in one in it by a plurality of bracing frames are firm, but on the inner ring of the ring-type slideway of outer ring slide relative, the outer ring of this ring-type slideway is packed on the inner edge of rim, on the outer rim of rim, tire is installed, two front-wheels that tricycle frame is installed are symmetrically placed in the both sides, front side of this ring-type slideway, the trailing wheel of tricycle frame in the ring-type slideway and this trailing wheel constitute by the interior fluted disc that is meshed with foot-operated chain and an outer tooth disk of integral production, this outer tooth disk is packed on the ring-type slideway inner ring and the active fluted disc coaxial integral production of a rotating disk by driving chain engagement, the uniform teeth that are shaped on of the outer rim of this rotating disk, these teeth are engaged on the chain wheel rim that lateral margin installed of ring-type slideway outer ring one side, on the inner ring of ring-type slideway the compartment are installed.

And described compartment is by the circular roof of transparent material, the osed top vehicle body constitutes all around, and the inner ring of circular roof and ring-type slideway is solidly installed, and the bottom of vehicle body is solidly installed by the inner ring of link span and ring-type slideway.

And the front end in described compartment installs the headstock of a conic tube, and the rear end in described compartment is fixed with a tailstock.

And, described rotating disk and initiatively fluted disc be installed on the support in the place ahead, inner ring bottom of ring-type slideway.

And described ring-type slideway is a rolling bearing structure, or oily pad bearing structure.

Advantage of the present utility model and good effect are:

1. the dry skating three-wheel vehicle in this band compartment is packed in vehicle frame on the inner ring of ring-type slideway, driving outer tooth disk when fluted disc rotates in the foot-operated chain drive when riding rotates, fluted disc drives dial rotation thereby this outer tooth disk drives initiatively by the driving chain engagement, the chain wheel rim that this rotating disk engagement ring-type slideway outer ring is installed, realize the rotation of ring-type slideway, but the advancing of three-wheel vehicle two front-wheel balances ring-type slideway.Whole transmission design design science is reasonable, and the ring-type slideway roll mode that adopts has reduced the friction force in the transmission, and moving velocity is very fast, and it is steadily reliable to advance.

The dry skating three-wheel vehicle in this band compartment on the inner ring of ring-type slideway, install a top and around the osed top compartment, this can be used for windproof keeping off the rain, and has stronger utility function.Changed traditional type of drive, its reasonable in design, cheap for manufacturing cost.

3. the dry skating three-wheel vehicle structure design novelty in this band compartment, science and reasonably on three-wheel vehicle, used dry skating skidding principle of work, the intention novelty designs originally, has amusement function, can be used as urban transportation tool or tour in the field's the leisure vehicle.
