Description

Super miniature bullet vehicle

The utility model relates to the automotive engineering field, is to be applicable to take in the general individual and the vehicle of family.

Automobile is indispensable a kind of vehicle in national economy and the social life, and it is closely bound up with society and people's lives.After the reform and opening-up, along with the raising of living standards of the people, many people want to have a self-propelled vehicle to ride instead of walk.But common people take in limited, are difficult to purchase a C-class as the vehicle of going out, and can only put bicycle or motor bike and use.Current popular two-wheeled motor vehicle has two disadvantages, and the one, poor stability, driving technique requires high, and women or older people are inapplicable.The 2nd, no cover panel, it is hot and feel very discomfort winter among cold to make the people be in summer, and in addition road environment is poor, and the dirty all over the body dirt of going out one time is painful.In addition according to new patent searching, detect relevant patent documentation as " miniature top alive tricar " (CN2113929U), " closed motor automobile " (CN2120745U), " elliptical Motordriven vehicle " (CN1040176A), " superminiature three-wheel car " (CN2143573Y) or the like, they are all different with the utility model with aspect of performance in structure.Find no the patent documentation report identical with the utility model.

For fear of limited etc. the deficiency of poor stability, Applicable scope and the applicability of general motor bike, it is a kind of based between motor bike and the baby car that the utility model provides, collection novelty, applicability, economy, safety, recreational be individual or the family's ideal vehicle--superminiature bullet car of one.

The utility model is by head light (1), preceding Cornering Lamp (2), windshield, (3), car door (4), front chair (5), vehicle body (6), rear wheel cover (7), back seat (8), back mirror (9), back Cornering Lamp (10), brake signal lamp (11), wheel flutter (12), front fork-front shock absorber (13), universal-joint (14), brake pedal (15), lengthening bar (16), vehicle frame (17), throttle (18), tween drive spindle (19), utmost point wheel (20), rear chain (21), rear suspension (22), drg (23), rear power wheel (24), rear shock absorber (25), pedal of clutch (26), operator is (27), meter system (28), driving engine (29), engine sprocket (30), preceding chain (31), intermediate chain wheel (32) is formed.Its architectural feature is:

1, the chassis is the regular three-wheeled motor bassinet structure, be that front-wheel is wheel flutter (12), front shock absorber (13) adopts the Motorcycle Front Fork structure, it connects lengthening bar (16) by universal-joint (14), prolong operator (27), be convenient to the operation of operator's reclining posture, direct connection does not have lengthening bar between the front fork bumper of general motor bike and the operator handle, can only be the striding type operation; Two trailing wheels are power wheel (24), be provided with tween drive spindle (19) between driving engine (29) and the power wheel (24), the two ends of tween drive spindle (19) are provided with utmost point wheel (20), the centre is provided with intermediate chain wheel (32), engine sprocket (30) drives intermediate chain wheel (32) by preceding chain (31), and the utmost point that passes through tween drive spindle (19) two ends is taken turns (20) and two rear chains (21) difference transmission two rear power wheels (24).It is simple in structure that system is adopted in this transmission, can play the effect of diff again.

2, rear suspension (22) is the swing arm type independent suspension, directly is assemblied on the tween drive spindle (19), simplifies the structure like this, has played the independent suspension effect, has improved riding comfort, makes rear shock absorber (25) good damping effect.The back power suspension of chain gear both at home and abroad all is a dependent suspension at present.

3, vehicle body (6) is an integrated carrying-type, and promptly vehicle frame (17) is welded as a whole with vehicle body (6).Body contour such as bullet-headed, streamline contour is good, windage is little, can improve moving velocity.

When 4, head light (1) need not throw light on, can regain in the vehicle body (6),, keep the car load outward appearance to reduce windage by hand lever, the drawing back function of this head light, not domestic the employing, external high-grade sport car adopts and rises automatically and retraction mechanism.

5, car door (4) adopts flip-shell, and promptly middle the upper half car bonnet changes novel structure, simple, easy for going up and down to a rollover.

6, drive seat front chair (5) and be the front and rear series type with back seat (8), can set up a little seat between front chair (5) and the back seat (8), take for child, occupant's both legs fork of back seat lies in the driver's of front chair both sides, as by motorcycle, this driving armchair structure compactness, vehicle body center of gravity reduce, and the center symmetry has improved the stability that car load travels.

The utility model is compared with the improved C-class of other similar motor tricycles following advantage:

1, as some above-mentioned constructional features, this car integral structure is simple, compact and reasonable, integrated carrying-type vehicle body, independent suspension, take advantage of the seat comfortable, in light weight, center of gravity is low, safe and reliable, easy and simple to handle, whole body contour is as sub warhead, and streamline contour is good, and is handsome in appearance, novel.

2, because this car is a kind of vehicle of development design-calculated on the motor bike basis, most of assembly and parts are all selected the same displacement motorcycle part for use except that vehicle body, so parts have reached universalization.Body outer skin is compared with the same displacement motor bike, the small-sized cover panel of motor bike, ornamental trimming are many, and this car is whole cover panel, reduced annex, overall cost is approximately higher than the 30-40% of similar discharge capacity motor bike, and to compare price much lower with general miniature small passenger car, this car fare lattice about about 1.5 ten thousand, easy like this entering in the general resident family of China also is that the desirable cheap and good-quality traffic worker of the general resident of developing country is individual.Therefore, in China and South East Asia and developing country's broad market prospect, the utility model will demonstrate better economic and social benefit.
