Description

Quadricycle

Technical field

The utility model relates to a kind of vehicle, particularly a kind of bicycle.

Background technology

Bicycle is the vehicle that people use always, is subjected to the restriction of its structure, can only carry a spot of goods, and the stability of bicycle is also bad, and particularly under low-tach situation, center of gravity is very difficult to be controlled.Same three-wheel vehicle is subjected to the restriction of its structure, when turning, because center of gravity in the outside, also is difficult to control, and then overturns easily.When three-wheel vehicle was loaded with goods, because the front portion has only a wheel, the load capacity of anterior wheel substantially exceeded the load capacity of the single wheel in rear portion, thereby front-wheel is bad easily in using, and above-mentioned defective is because the structure limitation of three-wheel vehicle self causes.

The utility model content

The utility model has overcome that low speed driving crank in the prior art, load carrying ability are low, poor stability, the deficiency that is difficult to operate, and a kind of quadricycle device is provided.

In order to solve the problems of the technologies described above, the purpose of this utility model can realize by following technical scheme:

A kind of quadricycle, comprise vehicle frame, steering hardware, described steering hardware is made of with the handlebar that is arranged on the vertical pivot upper end the sleeve that is enclosed within on the universal front fork vertical pivot, vehicle frame and sleeve link, on two front forks at universal front fork transverse axis two ends, be respectively arranged with wheel, be respectively arranged with two wheels at the rear axle two ends of vehicle frame.Be provided with bearing in the described sleeve, vehicle frame is provided with hood and baffle plate, the rear axle of vehicle frame is provided with flywheel, storage battery, flywheel and links to each other with motor by chain, handlebar is provided with back mirror, and the diameter that is installed in the wheel on the universal front fork transverse axis front fork is less than the wheel that is installed on the vehicle frame rear axle.Described vehicle frame is provided with air baffle and bumper.

Compared with prior art, the utility model quadricycle is because structure is more reasonable, thereby in use freely convenient, center of gravity can not be offset when turning, and, thereby has reliable and secure property and stability because its overall weight mean allocation is to four wheels.When trip,, overcome inclement weather and brought owing to be provided with hood and baffle plate InconvenienceIn needs, can also replace people's pedal by self-starting motor.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.

In conjunction with Fig. 1, Fig. 2 a, Fig. 2 b and Fig. 3, the utility model quadricycle steering hardware 1 by everything front fork 2, be enclosed within the sleeve 3 on the universal front fork 2, the front fork 4 that is arranged on the transverse axis two ends and front fork 5 and constitute.Vehicle frame 7 links to each other with sleeve 3.Chaufeur is by scrunching pedal 6, and application force acts on ground by chain 8, flywheel 9, wheel 13 and wheel 14, the handlebar 17 by universal front fork 2 vertical pivots upper end come controlling party to.Brake gear 18 is arranged on the lower right of vehicle seat 21.Chaufeur can reach the purpose of freely driving by being used of said apparatus.Be provided with bearing in the sleeve 3 on the universal front fork 2,, can also prolong the service life of universal front fork 2 simultaneously to reduce the friction between perpendicular horizontal stroke of universal front fork and the sleeve.Front fork 4 on the universal front fork 2 and front fork 5 are separately installed with wheel 15 and wheel 16, also can adopt shown in Fig. 2 b, and two wheels are installed in the transverse axis two ends of universal front fork 2 respectively.Steering hardware of the present utility model is simple, reasonable in design, and during use, fault rate significantly reduces, and safeguards also very convenient.The rear axle of vehicle frame 7 is equipped with two wheels 13 and 14.In the present embodiment, be arranged on two wheels on the universal front fork 2 at diameter less than two wheels that are arranged on vehicle frame 7 rear axles.The utility model is provided with four wheels, has overcome in low speed and the defective that turns to the crank under the situation, in the process of moving, has increased stability and reliability.Also cart or the three-wheel vehicle than routine is many greatly on load carrying ability.On vehicle frame, also be provided with hood 18, baffle plate 20, bumper 22, air baffle 23, during trip, can be in burning sun The sun is shining fiercely down sunshade, if run into rainy, can also be used to keeping off the rain, and steadily comfortable in the way of advancing, increased the convenience and the enjoyment of many trips.Air baffle 23 can be set level, and makes things convenient for chaufeur to trample, and can also erect, and works the effect of keeping out the wind, and reduces wind to kneed influence, and effect is very obvious especially in the winter time.

The rear axle of the utility model vehicle frame 7 is provided with flywheel 11, links to each other with motor 10 by chain, provides power supply by storage battery 12.Normal conditions servant by pedal 6, chain 8, flywheel 9 to the utility model provide power by the handlebar on the steering hardware 17 come controlling party to, reach the purpose of use.But under the situation of load carrying ability than big or upward slope, shortage of manpower can provide electric power for motor 10 by storage battery 12 so that enough power to be provided, and motor 10 drives flywheels 11 for trailing wheel provides power, thereby reaches the purpose of use.Also can only provide power by motor 10, flywheel 11, storage battery 12, the people need only be by handlebar 17 controlling parties to, 12 control brake of braking, thereby reach the purpose of use.
