Abstract

The utility model discloses a three-point horizontal bicycle, which changes the structure and the appearance of an existing bicycle. A rider can sit on a seat (10) in a semi-sitting and semi-lying posture, the body of the rider can lean backwards while the both legs of the rider can stretch forwards, the rider pedals pedal plates (16) by feet, a main chain wheel (15) drives a bridge wheel (7) and then drives a small flywheel (9) at the center of a rear wheel (8), a handlebar (13) is disposed at the center of a bicycle frame (5), the bicycle is provided with two front wheels and a rear wheel, the wheels are in three-point arrangement, the bicycle frame is fixed when the rider riding the bicycle turns a corner, the two front wheels control the bicycle to turn the corner, and accordingly the three-point horizontal bicycle is safer and more stable.

Description

3 horizontal bicycles

Affiliated technical field

The utility model relates to a kind of bicycle, particularly can seat adjustable three points of contact horizontal bicycle for sleeping in.

Background technology.

Existing more than 200 year of bicycle is historical, as long as the various places, countries in the world have the people that bicycle is just arranged, has been too much, and it is one of the most suitable vehicle of a kind of huge numbers of families of entering.Bicycle does not have too big variation over more than 200 year, be historical as usual mostly, though various mountain bikes were arranged modern age, variable speed bicycle, folding bicycle, external form be still one as usual, do not have big variation at all.

Summary of the invention

The purpose of this utility model just provides a kind of 3 horizontal bicycles of big improvement, makes cyclist's seat adjustable, more comfortable horizontal bicycles that crouch that can half and half crouch, and use 3 firm technology make travel and stop more safe and reliable.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: at the vehicle frame upper forepart of a bifurcation font two front vehicle wheels are installed separately, three points of contact is constant when turning to, the rear wheel in rear portion, seat is equipped with steering handle at vehicle frame bifurcation word infall before rear wheel.Transmission device is the steel pipes that stretch out a rising 30 degree at bifurcation word fork, be equipped with cover on the steel pipe top, in cover, imput shaft is arranged, two ends are stretchers, in the imput shaft left side is sprocket wheel, sprocket wheel connects the transmission idler through chain, leads to idler, goes up the small flywheel on another sprocket wheel drive rear wheel of two sprocket wheels arranged side by side, constitutes the secondary transmission.Rear wheel is that driving wheel promotes two front vehicle wheels in front.Two front vehicle wheels are cantilever-type structures, and front truck wheel shaft and axis of orientation are an angle of 90 degrees axles, and little vertical shaft upwards penetrates in the axle sleeve of vehicle frame.Little vertical shaft lower end is fixed with direction lever, and two front vehicle wheels have direction lever, interlock plate, and shift fork is stirred gangbar and swung when the operation handlebar, reaches the effect that front vehicle wheel turned to about two whiles.The brake of car is by the disc brakes dish that is positioned on the rear wheel center, and the brake stone dead wire is upwards introduced hand brake and connected, and reaches the purpose of brake.Vehicle seat is a chair type, is rim brake on the seat right side, and the hydraulic shock-absorption energy disperser is arranged under seat, can reduce vibrations.

The beneficial effects of the utility model are:

The cyclist can partly crouch and stretch out both feet step drive sprocket on vehicle seats, drives rear wheel and advances, because three are taken turns into the triangle point type and support, its vehicle frame does not rotate yet even car is turned, and is very firm, ride comfort, driving, parking need not be played support, supported at three point safety and reliable.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Description of drawings

Fig. 1 is the front schematic view of 3 horizontal bicycles of the utility model.

Fig. 2 is the schematic top plan view of 3 horizontal bicycles of the utility model.

Fig. 3 is 3 horizontal bicycle front-wheels of the utility model and steering box generalized section.

1 front vehicle wheel among the figure, 2 direction levers, 3 traces, 4 shift forks, 5 vehicle frames, 6 base pipes, 7 idlers, 8 rear wheels, 9 small flywheels, 10 seats, 11 rim brakes, 12 water bumpers, 13 handlebars, 14 chains, 15 imput shaft, 16 stretchers, 17 little vertical shafts, 18 fronts wheel spindle.

The specific embodiment

3 horizontal bicycles shown in Figure 1, on the bifurcation font vehicle frame made from steel pipe, anterior separately two pipe ends are respectively pacified a front vehicle wheel.

Keystone configuration is by vehicle frame 5, front vehicle wheel 1, rear wheel 8 and base pipe 6 steering handles and vehicle seat 10 are formed, and the vehicle frame plane is the bifurcation font, it is steel pipe manufacturing, it is vertically to intersect the center at vehicle frame center bifurcation word that base pipe 6 is arranged at the center, is semi-circular handlebars 13 on base pipe 6 tops, and base pipe 6 bottoms are shift forks 4, fuse through base pipe 6 and handlebar, rotate handlebar 13 and stir trace 3 through shift fork 4, direction lever 2 can make front vehicle wheel 1 direction that swings.Little vertical shaft 17 on direction lever 2 and the front-wheel connects together, and two fronts wheel spindle 18 become 90 degree direction free to rotate with little vertical shaft 17 lower ends.

The transmission device of 3 horizontal bicycles shown in Figure 2 is: stretch out forward at vehicle frame bifurcation font center and 30 ° the steel pipe top of rising is welded with driving axle housing, imput shaft 15 connecting pin pedals 16 by being positioned at.Step the idler 7 of stretcher 16 drive sprockets rotation through chain 14 connection rear portions, idler 7 left ends are two sprocket wheels side by side, and the small flywheel of another sprocket wheel in chain connection trailing wheel drives bicycle and advance.Opposite side at trailing wheel is a brake disc, by the brake operation bar of stone dead wire to the seat right side, reaches the purpose of timely parking.Water bumper 12 is arranged below seat 10.
