摘要
本次設(shè)計(jì)課題來源于江蘇悅達(dá)專用車有限公司,主要根據(jù)總體結(jié)構(gòu)設(shè)計(jì)的要求對垃圾車車廂和排出機(jī)構(gòu)液壓系統(tǒng)進(jìn)行了設(shè)計(jì)。車廂是垃圾車的重要部件之一,主要起裝載、運(yùn)輸垃圾之用。運(yùn)輸過程中,不良機(jī)構(gòu)容易造成二次污染。根據(jù)設(shè)計(jì)要求,確定了廂體形狀和主要尺寸參數(shù),重點(diǎn)考慮它的密封性;排出機(jī)構(gòu)主要是用來排卸垃圾以及在垃圾裝載時(shí)提供一定的背壓力,使壓縮后的垃圾密度均勻;在設(shè)計(jì)過程中,首先計(jì)算液壓缸的外部載荷,然后根據(jù)結(jié)果計(jì)算出液壓缸的主要參數(shù),進(jìn)而一步步確定液壓系統(tǒng)中其他元件的參數(shù)。

Abstract
This design topic is from Jiangsu Yueda Special Vehicles Co.,Ltd. According to the total design requirements, it is mainly aims at the garbage truck compartment and vehicle discharge mechanism design. The compartment is one of the important parts mainly for the loading, transportation trash. In the transport process, bad structure is easy to result in secondary pollution. According to the design requirements, the compartment’s shape and the main size are designed. However main focus into its undergo. The discharge mechanism is mainly used to provide the certain backpressure which compresses the garbage density evenly. In the design process, the hydraulic tank external load is first calculated. Then the main hydraulic tank parameters are calculated. Thus the following parameters are defined.
Key words: garbage truck; modified cars; upload; compression type;
