At present, no special chassis of the motor home is available in China, so that only the chassis of the light truck can be selected when the motor home is manufactured and modified by motor home manufacturers, and the cab, the container and the engine are directly and rigidly connected and fixed on a crossbeam of the chassis of the vehicle due to different design ideas and use purposes of the light truck. The crossbeam is fixed with the wheel axle (bridge) through the shock-absorbing steel plate, the inherent defects of large vibration, large jolt and large noise exist, and the caravan box body and the auxiliary beam are directly fixed on the crossbeam of the caravan when the caravan is modified, so that the vibration, jolt and noise generated by the road surface and an engine are directly transmitted into a car of the caravan, and the noise in the car can reach more than nearly 85 decibels even on a good high-speed road. When the road surface is slightly poor, the noise is removed, strong jolt and vibration occur in the vehicle, and equipment and tools in the vehicle are driven to vibrate and even be damaged.
In order to reduce vibration and noise, air bags are arranged at the positions of a wheel shaft (bridge) and a vibration-absorbing steel plate of a crossbeam of a vehicle chassis in parallel in the conventional part of manufacturers, but the wheel shaft and the crossbeam are still tightly fixed by the original vibration-absorbing steel plate, so that the vibration and noise generated by tires and the ground in the process of moving a vehicle can still be transmitted to the crossbeam, an upper box body and a cab fastened on the crossbeam through the fastening vibration-absorbing steel plate; because the engine is fixed on the crossbeam, the noise and vibration generated by the engine are not reduced at all, and the mounted air bag only shares the bearing capacity of the shock-absorbing steel plate, so the effect of shock absorption and noise reduction of the motor home realized by the method is very little. At present, the problems of noise and vibration become fatal pain points which cannot be overcome by refitting the caravan by adopting a light truck or a mini-truck chassis, and even seriously restrict the improvement of the level development of the caravan.
