Description
Technical Field
The invention relates to the technical field of automobile parts, in particular to a carriage front wall assembly.
Background
Along with the propaganda and promotion of energy conservation and emission reduction, the application of aluminum profiles in the industrial field is wider and wider, and particularly in the automobile field, the large and medium buses with all-aluminum vehicle bodies are promoted at present.
Conventional large and medium buses, whether full-load or semi-load chassis, generally employ steel body structures, which are very heavy in overall weight. The self weight of the vehicle body consumes about 70% of energy. Research data show that the fuel efficiency can be improved by 7-8% when the self weight of the automobile is reduced by 10%; the oil consumption can be reduced by 0.3-0.6 liter per hundred kilometers when the mass of the vehicle is reduced by 100 kilograms; therefore, the primary problem of reducing the energy consumption of automobiles is how to reduce the weight of the automobiles, and the handling performance such as acceleration performance and braking distance of the automobiles can be greatly improved after the automobiles are lightened. The automobile can achieve the purposes of energy conservation and emission reduction only through the light weight of the automobile, and the comprehensive performance of the automobile can be improved. With the increasingly prominent energy and environmental problems and the increasingly strict national one hundred kilometers of energy consumption and exhaust emission standards of automobiles, how to lighten the weight of the automobiles is one of the primary technical problems currently faced by the automobile industry.
Particularly, if the body material and structure of a pure electric new energy automobile are not changed, the weight of the pure electric new energy automobile is increased by 20-40% after a power battery and other energy storage equipment are installed, and the self-service quality of the pure electric new energy automobile seriously affects the load capacity and the endurance mileage of the pure electric new energy automobile. Therefore, the weight reduction of the vehicle body is more urgently required for the battery-driven new energy vehicle than for the conventional vehicle. Due to the restriction of the weight of the power battery and the battery endurance mileage, the light weight of the vehicle body becomes the first problem to be considered in vehicle enterprises in terms of vehicle design and material application. Because the self weight of the vehicle body is reduced, the loading quality can be increased, the power load can be reduced, and meanwhile, the resultant force borne by chassis parts can be greatly reduced, so that the controllability and the economy of the whole vehicle are more excellent. Particularly for new energy automobiles, the influence is not only weight, but also more important influence on unit load energy consumption and endurance mileage. Therefore, the reduction of the self-service quality of the new energy automobile is an important way for reducing the unit load energy consumption and improving the comprehensive performance such as endurance mileage.
