1. The non-bearing body noun
refers to a non-bearing body carrying the entire vehicle body frame, the engine, suspension and body are mounted on the frame, the frame One form of a chassis base for fixing the vehicle body and a fixing screw spring.
non-bearing body of the car has a rigid frame, chassis, also known as large beams. Frame and connected to the vehicle body by a spring or rubber for flexible connection. Engine, part of a drive train, automobile body assembly member fixed to the frame, the frame coupling the front and rear suspension means by a suspension means and the wheel. This non-Unibody relatively bulky, high quality, high altitude, generally used in trucks, buses and off-road jeep, there are a small number of limousine use, because it has better stability and security.
2. The characteristics of the non-bearing body
advantages
● high body strength, can provide strong steel body rigidity. This is very important for trucks and SUVs for. Suspension of the bumpy road feedback feeling in the car is much minor, because the connection with the method of reducing vibration between some car body and chassis, so when bumpy road to go more smoothly comfortable.
● a separate beam, high strength chassis. Generally used in trucks, buses and off-road jeep.
● four wheels again uneven force, is borne by the frame, and not transmitted to the vehicle body up. So SUV and off-road vehicle use more. Non-full-load-type body in our country bus companies which use very much.
● elastic body and the frame member are coupled, has a certain shock absorption effect. When traveling on the road, you will feel more stable.
shortcomings
● When danger (such as roll-over), the heavy chassis, will be relatively weak lethal threat to the body.
● large weight, the frame itself is very heavy, the body and frame is two separate components, the overall weight is even greater, with a plurality of steel, the cost is relatively high.
● High car centroid. The center of gravity higher than carrying vehicle. At the bottom of the frame, while the body is mounted on the frame, then the body of the frame above the floor anyway.
