Description

Double front wheel U type vertical steering handle chair form three-wheel car

The utility model relates to a kind of double front wheel U type vertical steering handle chair form three-wheel car that is used for the vehicle, belongs to the product of field of vehicles.

Existing motor bike comprises that fuel oil or battery-operated motor cycle have two-wheeled and two kinds of structures of three-wheel, and it turns to all is to rotate by promoting T type V shape handlebar, and a front-wheel realizes thereby drive, and the chaufeur sitting posture is generally straddle-type.Though such structure is simple and direct, its inherent defect is arranged also.At first, existing motor bike is the wheel flutter in front; Particularly concerning the two-wheel motorcycle of quantity maximum, its stability, safety are relatively poor, and steering shaft is far away from the operating seat front distance, the chaufeur two arms handle that protracts must cause centre of body weight reach, head surpasses centre of body weight, when high speed is travelled, if the front bumps, the cephalothorax often that comes to harm at first.In fact, the casualty accident that is caused by motorcycle is that cephalothorax is by wound more than 80%; Secondly, the reach of the center of gravity of chaufeur also causes two arm numbnesses; The 3rd, 70% of existing motorcycle driver body wt drops on perineal position, drives for a long time to make this position can produce certain sense of aching, and is very uncomfortable; The 4th, owing to limit on the existing motorcycle structure, various motor bikes all should not install front bumper and safety strap additional; Two-wheel and side (limit) motor-tricycle can't install closed hood additional, can not keep out wind and rain to chaufeur, and single front-wheel steering is also easily turned on one's side.

Though existing small passenger car is not only safe but also comfortable, because its complex structure, cost is higher, lacks economy, alerting ability than motor bike.Simultaneously, existing car mostly utilize the bearing circle controlling party to, and bearing circle also is to be positioned at chaufeur chest dead ahead, in case clash into, easier extruding chaufeur chest damages to chaufeur.Though utilize safety strap can reduce and avoid this injury,, be unfavorable for the chaufeur escape in some cases because of safety strap links to each other with seat; And its wheel steering complex structure not only takes material, and requirement on machining accuracy is also high, and maintenance is complicated, and cost is also higher.

The purpose of this utility model will provide a kind of novelty, safe, comfortable exactly, economic, the vehicle flexibly.

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is by two front-wheels arranged side by side (1), driver's seat (2), the vertical handle-bar of U font (3), main beam (4), vehicle frame (5), driving engine and transmission device (6), trailing wheel (7), closed bicycle shed (8), vertical shaft (9), vertical shaft sleeve pipe (10), seat (11), forward and backward bumper/spoiler (12), safety strap (13), turn to driving lever (14), turn to driving lever cover (15), tierod (16) and kingpin (17), kingpin cover (18), spindle arm (19), part such as wheel shaft (20) is formed.Its concrete steering mode is: driver's seat (2) is supported, has been replaced traditional bearing circle or T type V shape handlebar with the vertical handle of U type by the vertical shaft (9) that is fixed on the crossbeam (4).Two vertical handlebar apportion driver's seat both sides, the cross sill of U type handle is positioned under the driver's seat and connects with vertical shaft sleeve (10), in vertical shaft sleeve (10) bottom a L type direction driving lever (14) is arranged, by driving lever cover (15) drive intermediate rod (16) thus driving front-wheel steering arm (19) rotates and drives transverse axis (20) along vertical shaft (17) and realize turning to together with wheel (1).

The utility model has increased safety strap again between two vertical handlebars.Safety strap one end is fixed on a sidecar last, and the other end can be enclosed within on the opposite side handlebar easily, can adopt hasp to connect, and not only increases safety factor but also be convenient to flee from.

Get on and off for ease of chaufeur, the utility model car door (21) is preposition, lifting type, and car door is connected with hood by the hinge (22) on hood top.When travelling, chaufeur rides on the seat (2), and the both legs natural torsion is simultaneously with foot control system throttle and brake; Health is layback slightly, leans against seat back, centre of body weight is scattered on the whole seat and after the posture more by motorcycle moves, and when bump takes place, can at first not injure head and upper body, has so just reduced extent of injury to greatest extent.Also increased simultaneously the comfort level of chaufeur greatly, front-wheel changes two into by original one, and this can increase the stability and the safety of car load greatly, and seat (11) is positioned at rear axle and car bonnet top, owing to do not adopt saddle, thereby improved occupant's traveling comfort and safety greatly; Front and back wheel can be configured to the first two back same form, can take occupant one people, also can dispose the four-wheel-type of the first two back two, can take occupant 2 people.Driving engine can be a combustion engine, also can be that electrical motor provides the power driven trailing wheel.Because two front-wheels are arranged, front frame is widened, and is convenient to and back vehicle frame together support, installs closed hood additional, also is beneficial to before the car and installs bumper/spoiler (12) additional.So just formed economic, small and exquisite miniature three-wheel car.

Other is as driving engine, transmission device, brake system, the structure of oil circuit, circuit, lighting system etc. is known technology, needn't give unnecessary details at this, form the comfortable safety of the existing car of collection and the economic flexible double front wheel U type vertical steering handle chair form three-wheel car of one that is of motor bike thus.

Description of drawings: figure one is the car load scheme drawing, and figure two is the steering swivel system structural representation.

Among the figure: (1) front-wheel, (2) driver's seat, (3) U font handle-bar, (4) main beam, (5) vehicle frame, (6) driving engine and transmission device, (7) trailing wheel, (8) closed hood, (9) vertical shaft, (10) vertical shaft sleeve pipe, (11) seat, (12) forward and backward bumper/spoiler, (13) safety belt, (14) L type turns to driving lever, (15) driving lever cover, (16) steering track rod, (17) kingpin, (18) vertical shaft sleeve, (19) spindle arm, (20) front wheel spindle, (21) driver door, (22) hinge.
