1 body
Introduction:
The main role of the vehicle body is configured to protect the driver and good aerodynamic environment. Good body can not only lead to better performance, but also reflects the owner’s personality. Form from said vehicle body structure, it is divided into non-bearing and load two.
Requirements:
auto body cope with drivers to facilitate working conditions, providing a comfortable ride for the crew conditions, to protect them from vibrations when cars, noise, bad weather outside invasion and impact of exhaust gas, and to ensure that the carriage of cargo intact and easy loading and unloading. Vehicle body structure of some of the measures and equipment also contribute to road safety and mitigate the consequences of accidents.
car body shall have a reasonable assurance outer shape, when the cars can effectively guide the air flow around, in order to reduce air drag and fuel consumption. Further, the body should also help to improve vehicle stability and improved running condition of the engine cooling, and to ensure good ventilation inside the vehicle body.
Auto Body is a comprehensive fine art, sculpture should be clear in their body, elegant trim and interior decorative materials and pleasing colors people get the feeling of beauty, embellishment people’s living environment.
The basic structure:
The main vehicle body structure comprising: a housing body, doors, windows, plantain sheet metal parts, both inside and outside the body trim and body accessories, seats and ventilation, heating, cooling, air conditioning units and the like. On the truck and special vehicle also includes carriages and other equipment.
All vehicle body mounting base housing is a body member, generally refers to a rigid structure of vertical space, beams and pillars, and the like load-bearing element and the sheet metal parts are connected together thereof. Most bus body has significant boneFrame, while the car body and truck cab is no clear skeleton. Further comprising a housing body generally laid thereon noise, heat, vibration, corrosion, sealing materials and coatings.
by a door hingedly mounted on the body housing, which structure is more complex, is to ensure that performance is an important component of the vehicle body. Sheet and so on. The formed article made of a sheet space for receiving an engine, wheels and other components.
Category:
First, the non-bearing body
non-bearing body of the car has a rigid frame, chassis, also known as large beams. In the non-bearing body of the engine, part of the transmission system, the body assembly, and other parts are suspension means fixed to the frame, the frame by the suspension means is coupled with the front and rear wheels. Non-Unibody relatively bulky, massive, high altitude, usually used in trucks, buses and off-road vehicles, as well as some advanced cars used because it has better stability and security.
Second, the monocoque
monocoque vehicle chassis is not rigid, but the strengthened front, side panels, the rear portion of the bottom plate and the like, the engine, front and rear suspension, transmission the other part of the vehicle body assembly member fitted position of the design requirements, the load of the vehicle body to the wheels by the suspension means. Unibody addition to its inherent function of the ride, but also directly receives various loads acting forces. Unibody whether in safety or stability has greatly improved, it has a small mass, low height, easy assembly, etc., most cars use such a body structure.
Common decoration:
The main body of the external garnish refers trim, wheel cap, logo, text, etc. embossed. Radiator cover, bumper, lamps and mirrors, and other decorative accessories are also obvious.
vehicle interior trim member comprising an instrument panel, roof, side walls, seats and other accessories surface coating, as well as curtains and carpets. Widely used in the automobile textiles of natural or synthetic fibers, leather or multilayer composite, integral skin foams and other decorative material surface; the extensive use of fiberboard, cardboard, plastic sheet, aluminum sheet, a rubber sheet on the pattern and bus composite decorative material such as decorative panels.
CartAccessories Body:

In some truck cab and the passenger compartment is also set to adapt sleeper night long-distance traffic needs. To prevent the occupant when
In order to ensure traffic safety, widely used in modern automobiles is applied to the occupant restraint webbing, headrests, and automotive airbag collision:
Other facilities various buffer device and a packet pad injury. According to different types of carrier goods wagons may be an ordinary truck field plate structure, the platform structure, dump structure, closed wagons, gas, liquid cargo tank and transport granular (grain, powder, etc.) used in pneumatic blowoff special containment tank or standard for all roads, railways, waterways, air transport and international transport of containers.
