Abstract
The utility model relates to a technical field of bicycle manufacture, in particular to a long-distance ranch wagon. The long-distance ranch wagon comprises a wagon body part, a traveling part and a driving part, wherein the driving part comprises two chains, two flywheels and two gears all symmetrically arranged on the wagon body respectively; a chain adjuster used for adjusting chains is mounted on a middle pipe; the traveling part comprises front and rear wheels provided with tyres; the tyres comprises tyre bodies; the tyre bodies includes tyre noumena, anti-explosion layers and tyre surface layers; the anti-explosion layers are arranged between the tyre noumena and the tyre surface layers; surface layers provided with a plurality of glass particle layers are arranged on the external surfaces of the tyre surface layers. As the driving parts is divided into two groups, so that the consistency of the stresses on a rear axle and the flywheels is ensured, the cheapness of the rear axle is avoided, and the service life of the driving part is prolonged; as the bicycle tyres adopt a three layers structure, so that the phenomenon of a flat tyre caused by long time riding is avoided.
Description
Technical field
The utility model relates to bicycle manufacturing technology field, relates in particular to a kind of long-term travel car.
Background technology
Bicycle has been dissolved into as the vehicle in people's life, along with the change of people life style, the various bicycles with certain special purpose that obtain that improve taking bicycle as basis enter in our life gradually, for example for the mountain bike of body-building, for improving derailleur of speed etc.Mainly be divided into following several part: body part comprises vehicle frame, front fork, handlebar, saddle and front forked assembly etc.; Running part comprises pedal, crank, sprocket wheel, chain, axis and flywheel etc., steps on pedal by manpower, drives rotation of wheel by above Transmission, drives to move ahead; The part of advancing is front and back wheel, comprises antero posterior axis parts, spoke, wheel rim, tire etc.; Safety device comprises brake, car light, bicycle bell, reflective devices etc.
Prior art middle-long distance este wagon has following shortcoming: running part is contained in a side of bicycle, flywheel mostly only has one, standard bicycle is often subject to the application force of a side like this, cause the stressed of two tires can not be point-blank, thereby cause the skew of the rear axle of bicycle, in the situation of riding for a long time, can bring danger to tricycle, finally cause rear axle to scrap, affect long distance travelers and continue to use; Often can cause wheel to be blown out owing to riding for a long time in addition.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of long-term travel car is provided, and improves the service life of bicycle running part and tire.
The utility model for achieving the above object, by the following technical solutions:
A kind of long-term travel car, comprise: comprise body part, advance partly and running part, described body part comprises pipe, lower pipe, middle pipe, rear stays, rear chain stay, described lower tube-in-tube and rear chain stay connect by five-way, and described upper pipe is connected with the top of described middle pipe respectively with rear stays; It is characterized in that: described running part comprises chain, flywheel and gear, described chain, flywheel and gear are respectively two, and symmetry is arranged on car body, on described middle pipe, the chain adjuster for adjusting chain are installed; Described travel section is divided and is comprised forward and backward wheel, on described forward and backward wheel, tire is installed, described tire comprises carcass, described carcass comprises tire body, explosion-proof layer and tread ply, wherein explosion-proof layer is arranged between tire body and tread ply, the outside face of tread ply is provided with a top layer, and multiple glass granules layers are contained on this top layer.
The beneficial effects of the utility model are: the utility model is simple in structure, because running part is two groups, have ensured the conformability that rear axle and flywheel are stressed, have avoided rear axle cheap, have improved the service life of running part; Bike tyre is divided into three-decker, has avoided bicycle because ride for a long time and produced the phenomenon of blowing out.
Brief description of the drawings

Fig. 2 is the cutaway view of tire in the utility model;
In figure: 1, chain; 2, flywheel; 3, gear 4, chain adjuster; 5, tire; 6, carcass; 7, tire body; 8, explosion-proof layer; 9, tread ply; 10, glass granules layer.
Detailed description of the invention
Describe detailed description of the invention of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As depicted in figs. 1 and 2, a kind of long-term travel car, comprise: comprise body part, advance partly and running part, described body part comprises pipe, lower pipe, middle pipe, rear stays, rear chain stay, described lower tube-in-tube and rear chain stay connect by five-way, and described upper pipe is connected with the top of described middle pipe respectively with rear stays; Described running part comprises chain 1, flywheel 2 and gear 3, and described chain, flywheel and gear are respectively two, and symmetry is arranged on car body, and the chain adjuster 4 for adjusting chain is installed on described middle pipe; Described travel section is divided and is comprised forward and backward wheel, on described forward and backward wheel, tire 5 is installed, described tire comprises carcass 6, described carcass comprises a tire body 7, an explosion-proof layer 8 and a tread ply 9, wherein explosion-proof layer is arranged between tire body and tread ply, the outside face of tread ply is provided with a top layer, and multiple glass granules layers 10 are contained on this top layer.
The utility model is simple in structure, because running part is two groups, has ensured the conformability that rear axle and flywheel are stressed, has avoided rear axle cheap, has improved the service life of running part; Bike tyre is divided into three-decker, has avoided bicycle because ride for a long time and produced the phenomenon of blowing out.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
