The vehicle body structure according to the forces into non-load bearing, and the carrier semi-integral three.
1. Introduction of the body structure
The vehicle body structure according to the forces into non-load bearing, and the carrier semi-integral three. Basic description
2. The non-bearing body
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.
3. Monocoque basic introduction of
monocoque vehicle chassis is not rigid, but the strengthened front, side panels, rear, other parts of the bottom plate, the engine, front and rear suspension, a portion of a drive train assembly, and other components are assembled in the desired position on the vehicle body design, the load of the vehicle body to the wheels by the suspension means. This unibody addition to its inherent function of the ride, but also directly receives the force of the various loads. After decades of development and improvement, Unibody, whether in security or in terms of stability has greatly improved, with a low mass, high and low, no suspensions, easy assembly, etc., so most cars such body structure adopted.
4. Introduction of semi-monocoque
connected to the vehicle body frame with screws, caulking, or the like welding method is rigidly connected. In this case, in addition to an automobile body subjected to the above loads, the reinforcing frame also contributes to some extent, share part of the load frame.
