Abstract
The utility model relates to a front pedal seating-typed three-wheel cycle in the field of traffic tools, which is combined with the front wheel frame and the back wheel frame. The front wheel is small and the back wheel is great. The front wheel frame is welded with a front vertical pipe and 4 steel pipes for an integrity. The inside is divided into two triangles with the front vertical pipe of the supporting front wheel as the center, with the front triangle positioned with the chain rotating shaft and the back triangle frame connected with the back wheel frame. The back wheel frame is composed of a plane frame by two fork-typed elbow pipe and reinforcement pipe and two rotating shafts of the back wheel. The high backrest seat is integral with the storage box, which is installed on the back wheel frame and positioned with the vibration-absorption device. The front of the cycle is positioned with the anti-collision fender-guard. The utility model is novel in design, reasonable in force, cozy for seating, great in speed, stable in driving and safe for driving, in particular applicable to the middle-aged and the elders and the people who do not learn to drive bicycle. The three-wheel cycle is the traffic tool highly safe on the road for purchasing and going to work, which can also be used as the novel sport tool.
Description
Technical field
The utility model relates to a kind of front drive tricycle, belong to field of vehicles.
Background technology
Traditional bicycle adopts the striding type design, and its principal feature is the position of pedal crank assembly, between the what front and rear wheel of position.The cyclist is by its health of triangular shape Saddel receiver, and there is following weak point in this class design:
One, cyclist's body weight is supported by the pelvis lower recess.Bipod is to have an effect downwards basically, so the saddle level generally should be greater than rider's lower limb length apart from floor level.It is low that thereby vehicle seat can not design.Cyclist's center of gravity is higher, has increased cyclist's insecurity, has also increased to act on cyclist's frontal resistance on one's body.The pelvis bottom is stressed in the time of by bike concentrates, can feels pain and fatigue when ride period is long.
Two, be designated as A as if hip joint with cyclist's human body, cross human body upper body center line that A orders on one side, the chain drum axle center of pedal crank assembly and A order on line be another side, the angle on both sides is designated as force angle α, traditional α angle by striding type design-calculated bicycle is very big, be about 160 °, make the shank mode of work-doing very unreasonable so by bike.The cyclist in fact be by thigh drive shank down presser feet pedal crank.The quadriceps muscle of thigh that is positioned at the thigh front side when having an effect is nervous simultaneously with the biceps muscle of thigh that is positioned at the thigh rear side, mutual obstacle, and energy internal friction is easy to generate fatigue.Posture by bike like this can not be brought into play the effects to having an effect such as human lumbar, muscle of back and gluteus maximus.
The commodity bicycle of employing front-treadle type structure yet there are no and emerges, and only accidental relevant design-calculated is sporadicly reported.But generally speaking structure is very complicated, and seat often is half lying posture, and the visual field is bad.F-w-d is mostly adopted in these designs, divides two classes on the structure again.One class is to adopt f-w-d, and front-wheel steering, and is firmly not too reasonable, and operation is very not smooth.Another kind of is f-w-d, and trailing wheel is driven to be turned to.Obviously when turning to, must need reverse operating, with custom antithesis, very inconvenience.Also the someone proposes f-w-d, and trailing wheel is driven when turning to, and adopts the rotating mechanism of annular arrangement or other circumferential direction disc types, and structure is quite complicated.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, a kind of front drive tricycle is provided, front-wheel is little, that trailing wheel is big front-treadle type bicycle structure and high back chair, sitting posture mode and tricycle to pedal combine, and form a kind of have brand-new pattern, rational in infrastructure, easily manufactured tricycle.
The utility model is achieved through the following technical solutions, the utility model is formed by front wheel frame and the connection of trailing wheel vehicle frame two parts, front-wheel is little, trailing wheel is big, front wheel frame is welded into as a whole by preceding standpipe and 4 steel pipes, and is the center with the preceding standpipe that supports front-wheel, and inside is divided into two triangles again, be provided with turning cylinder, chain drum, pedal crank assembly in preceding triangle, the Vee formation frame then is connected with the trailing wheel vehicle frame; The trailing wheel vehicle frame is by two fork-shaped bend pipes, and the turning cylinder of reinforced pipe and two trailing wheels is formed the planar shaped support; High back chair and wanigan are combined into integral body, are installed on the trailing wheel vehicle frame, and are provided with shock absorption device; The level attitude of high back chair, height and degree of dip are all adjustable; Car the place ahead is provided with anti-impact bumper.
Chain drum, turning cylinder are in the place ahead of preceding wheel shaft and preceding standpipe, and back-wheel drive, front-wheel steering.
In order to improve the comfort level of rider to pedal the time, adopt high back chair to add adjustable head rest as the car chair, high back chair and high capacity wanigan are linked to be integral body, but the front and back position of car chair, height and degree of dip free adjustment, and this does shopping for the rider and transportation is provided convenience.Case lid is arranged on the wanigan, and lockable.
Shock absorption device is formed by stacking by spring steel band and tubular spring two covering devices, article two, narrower spring steel band is as the first road glissando, be drilled with several apertures on the spring steel band, the distance that can suitably adjust between high back chair and chain drum is pedaled distance to satisfy rider's the best; Spring steel band is fixed on by screw rod and nut on the tubular spring on the supporting node of trailing wheel bearing support, as the second road glissando, by adjusting the nut on the screw rod, can adjust the height and the degree of dip of high back chair, so that the rider has the sitting posture of the most comfortable.The α angle of front drive three-wheel vehicle is 110 °-120 °.
Pedal crank assembly has the both feet that the plastics of reinforcing bar bumper/spoiler protection rider is arranged in the purpose made in the place ahead of front vehicle wheel, can carry additionally little container before the bumper/spoiler, and the little container of plastics plays buffer action, more increases safety.By chain flywheel on the hind axle is passed in the rotation of chain drum, establish left and right sides light deflector and small bell or dynamic loud-speaker on the handlebar, make the rider can see the situation at left and right sides rear clearly.
The utility model modern design, have an effect rationally, the visual field is good, comfort for sitting posture, speed are very fast, it is steady, as safe as a house to travel; Back-wheel drive, the mode of front-wheel regulation and control direction is not only convenient but also natural; The all desirable parts of a large amount of parts from traditional riding type bicycle, or based on the same principle transformation of the way; Seat, wanigan, little container etc. all can be made of plastic, and the exploitation ratio that car load is produced as merchandizing is easier to.This car is suitable for person in middle and old age person especially and can ride the people from all walks of life of bicycle, is the very high vehicle of safety of shopping and usefulness on and off duty, also can be used as the novel gymnastic apparatus that leisure and enure health are used.
