YD5141后装压缩式垃圾车的总体设计 Abstract In order to solve the problems of town garbage transportation, two contamination in the transportation, thus improve the transportation efficiency, and reduce the worker labor intensity, this paper has designed the entire seal compression type garbage truckThis topic first introduce the 5 principles in the overall design of back ward loading compression garbage truck, and then gave detailed proof analysis to the 5 principles. The author compares the new design with the traditional one. In design and the calculation part, the structure parameter of the garbage truck, and the engine of the dumpcart are chosen according with the requirements. According to the loading request, the design of the back ward loading compression type garbage truck are calculated, including the hopper volume and the dirt water tank volume computation. The motor car chassis is mainly on the chassis selections and the reformation, and the axes load distribution. In the same time, the entire vehicle performance parameter based on the standard has been selected, according to the imum speed, the fuel economy parameter, the mobile parameter and passed the parameter and so on; and to confirm the parameters of axes distance, the distance of the front and back wheels, and the size of outside profile. In order to guarantee the completed car performance, have done the stress and strength checking, the stress analysis and strength checking of liquid pressure system.
