Description

Bearing circle middle double cab four-wheel miniature car

Technical field

A kind of manned vehicle, the especially mid-get car of taking for 1-3 people.

Background technology

At present, a lot of economy cars, double car etc. are arranged, the two-wheeled motorcycle that but present most common people's running vehicle still is traveling comfort, safety can not show a candle to car (comprising that two take turns battery-driven car), why is this? it seems that existing economy car is economical not enough, be suitable for inadequately, compare very big weak point in addition with two-wheeled motorcycle.At first be that price, operating costs, energy consumption are all much higher than two-wheeled motorcycle, the car Heavy Weight, generally at least all more than good hundreds of kilogram, its energy consumption must be high, and most expenditure of energy is in the car body deadweight.And two take turns motor and generally have only about 100 kilograms, and the windage of travelling is little, and its energy consumption is little, the capacity usage ratio height.In addition, the economy car that has is not that outward appearance is bad, is exactly that applicability is not strong, for example: the outward appearance of three-wheel car, traveling comfort, safety are poor, and common people are beyond affordability, and single car of four-wheel and double car price are not low yet, can only take 1-2 people, its applicability is strong inadequately.In the ordinary people daily life, the condition of service of car is: about 70% is separately out using of individual, and about 20% is that two people use, and about 8% is that three people use, and has only 2% Occupation coefficient to belong to four to five people and uses.The shortcoming of existing double economy sedan is: bearing circle is positioned at the left side (or the right) of car, passenger-seat is in the right (or left side) of operator's saddle, this mode makes the width over sides of car body can not be very little on the one hand, make that its length over ends of body also can not be very short, otherwise the length of car is disproportionate, has a strong impact on outward appearance.Wide long again weight and the manufacturing cost that is unfavorable for reducing car of car body, and car body is wide can to increase the driving windage, increase energy consumption, also can increase and cause traffic to hinder the taking width of highway, the little highway in particularly inapplicable vast rural area (the little highway in rural area is generally all very narrow), its traffic potential is not strong, and it is big to take parking space; On the other hand, if car body is not enough wide, the passenger can have certain influence to the driver comfort and the safety of chaufeur, this mode is not emphasized the driver comfort and the safety of chaufeur, yet the condition of service about 70% in the life is the individual to be used, therefore passenger seat is placed the operator's saddle right side then (or left side) be inappropriate, applicability is strong inadequately.Moreover, be unfavorable for adopting the single rear wheel type of drive.

Summary of the invention

The purpose of this utility model provides a kind of bearing circle middle double cab four-wheel miniature car, accomplishes that width over sides of car body is little, in light weight, occupies little space, and traffic potential is strong, reduces resource and energy resource consumption, and productive costs is low, drives comfortablely, and safety performance is good.

The utility model comprises steering front wheel, drives trailing wheel, vehicle frame, hood, driving special seat, passenger seat, improvements are that the bearing circle of driving special seat the place ahead is located on or near the vehicle frame front, center, only at driving special seat rear passenger seat is set, the steering hardware of control wheel flutter is equipped with in bearing circle main shaft below.In order further to reduce car weight, two steering front wheels of the utility model are installed on the vehicle frame by the simple pendulum arm suspension gear respectively, and steering hardware adopts chain dynamic formula or geared.The working space of simple pendulum arm suspension gear is little, is specially adapted to small-sized economy sedan.As required, car door of the present utility model can be arranged on the and arranged on left and right sides of hood arbitrarily.

Compared with the prior art, the utility model has following characteristics:

1, use is with strong points, can take 1-3 people, is fit to the work and the living needs of ordinary people.

The driving special seat is only established in the vehicle frame front portion, do not establish passenger seat, operator's saddle and bearing circle are located on or near the midway location of the car body left and right sides, the driver comfort and the safety of chaufeur have been emphasized, the daily condition of service that is just meeting the common people, being that the individual is independent to the condition of service of car about 70% in the ordinary people life uses, therefore must emphasize traveling comfort and safety when the individual uses, passenger seat is located at the vehicle frame rear portion, the passenger is little to the influence of chaufeur, and can take 1 to 2 people, satisfy the daily use needs of ordinary people to a great extent.

2, width over sides of car body little (about about 1.25 meters of beam overall), it is little to take the highway passage space, and little to the traffic resistance, traffic potential is strong, is specially adapted to the little highway in vast rural area (the little highway in rural area is generally all very narrow) and takies parking space little.

3, simple in structure, in light weight, center of gravity is low, and windage is little, and energy consumption is low, and price is low, and operating costs is low, and driving safety is comfortable.

Because the driving special seat is only established in the vehicle frame front portion, passenger seat is established at the rear portion, and power (or battery) is installed in the vehicle frame rear portion, and adopts the simple pendulum arm front-end equipment, and chain is moving or the geared steering hardware, simplified body frame structure for automotive, reduced car body weight (about about 200 kilograms of car load net weight), width over sides of car body is little, and be streamline contour, center of gravity is low, and windage is little, and energy consumption reduces.
