绿化洒水车设计(三吨载重量)管路设计和喷洒部件设计(有cad图文献翻译)
绿化洒水车设计(三吨载重量)管路设计和喷洒部件设计摘要绿化洒水车具有除尘、清洁路面、植被和降温等作用,是城市绿化建设和卫生建设的专用汽车,随着人们对环境要求的不停提高,具有良好的市场前景。
这次设计的绿化洒水车(三吨载重),是在选择通用二类底盘的基础上,对它作了一些改动。
在设计中,主要完成了变速箱总成的改动,取力器总成的设计、水管总成的设计、水箱总成的设计和各总成的位置布置,而且保证了变动后的洒水车具有良好的动力性、操纵稳定性和行驶安稳性。
洒水车最典型的部分也就是洒水管路,此次设计的洒水车管路在设计方面与过去不一样的是各个管路在开关阀的作用下工作,不会影响各自管路的功能,使水泵在有效的工作环境中发挥有效的功能,洒水车工作方式是,水罐的水从出水管经过水管阀门与水泵进口相连,水泵出水口通过各水管阀门与各自的分水管相连,最后通过各喷洒系统,实现不同的的洒水功能。
洒水面在原来的基础上更能表现不一样,水泡总成减少了重量,而喷射距离在同工况下更优胜。

AbstractThis paper mainly designs a new type of entertainment equipment - amphibious bicycle. At present, open-wheel, water jet, propeller and other driving are widely used, among which the propeller driving mode is determined to be the best by comparing and calculating. According to the relationship between drag and velocity in hydrodynamics, it is concluded that the minimum drag can be achieved only when driving normally. Choose the most convenient transmission mechanism to design a water recreation vehicle which is concerned by many people in the world and easy to drive with high utilization rate.The amphibious bicycle is similar to the old-fashioned bicycle in terms of power, which is driven by manpower and transmitted power to the rear axle through chain drive. The two open wheels connected by the rear axle can control the longitudinal force independently and have no influence on each other, thus achieving the movement and steering of the amphibious bicycle on water.Realize the navigation and steering of bicycles on the water. The floating board is designed to be triangular and fixed with bicycles on both sides of the land. It can give customers some protection of their sense of safety when driving on water, making driving safe, portable and reassuring.Key words: amphibious bicycle, open wheel, water spray, drive, propeller.目录摘要 (I)Abstract (IV)目录 (V)第1章绪论 (1)1.1水上踏板自行车的来源 (1)1.2研究内容及背景 (2)1.3水陆两用自行车的研究目的与意义 (2)第2章水陆两用自行车的介绍 (4)2.1水陆两用自行车的构成 (4)2.2水陆两用自行车方案设计: (5)第3章传动系统 (7)3.1自行车传动效率计算 (7)3.2 传动比 (7)3.3链传动设计 (8)第4章明轮的设计 (10)4.1明轮简介 (10)4.2明轮的设计 (10)第5章轴的设计 (12)5.1链轮上的力计算 (12)5.2选取材料 (12)5.3轴的计算 (12)5.4轴的结构设计 (12)5.5 设计总结 (13)5.6专利介绍 (14)第6章浮力的计算 (17)第7章功率的计算 (19)总结 (20)致谢 (21)参考文献 (22)三维作品展示 (23)附录本次设计采购清单 (33)第1章绪论1.1水上踏板自行车的来源水上踏板自行车开始于加拿大。

毕业设计(论文)-绿化洒水车设计(3吨重量)变速箱取力器及水泵传动(含全套CAD图纸)
绿化洒水车设计(3吨重量)变速箱取力器及水泵传动摘要洒水车作为专用车的一种,在城市洒水和绿化中具有重要的地位。
随着城市化进程的不断加快,一方面城市绿化带不断增多,需要大量的洒水车对苗圃进行灌溉。
而由于城市环境的需要,绿化带的分布也越来越复杂,这就要求洒水车灵活且亦控制,也就是说,需要进一步提高洒水车的技术含量。
另一方面,随着城市居民对环保意识的不断加强,对街道、公路的清洁也越来越注重。
作为路面清洗设备的洒水车,其重要性不可低估。
再者,洒水车作业频率的提高和连续作业时间的延长,也对其使用的可靠性提出了更高的要求。
国内洒水车技术的开发和研制相对较晚,虽然数量比较多,但质量与国外洒水车相比还有较大差距,很多方面还存在问题。
设计一辆安全、可靠、耐用的洒水车非常必要,而且市场前景很广阔,市场潜力也很大。
改装洒水车主要是在原有汽车底盘的基础上增加一套能使洒水车完成吸水和喷洒等作业能力的压力系统。
压力系统由动气传动总成、水泵管路总成、水箱总成和操纵机构等组成。
传动总成的作用是将汽车发动机的动力传输给水泵,并满足水泵的转速要求。
本设计动力传递的路线是:发动机→变速器→取力器→水泵。
由此可知,动力传动的设计主要是对取力器进行设计。

With the urbanization process accelerating, on the one hand, the city green belt is growing and need a lot of the nursery right for sprinkler irrigation. And because the needs of the urban environment, green belts, the distribution is getting more complicated, which calls for sprinkler flexibility in terms of control, In other words, the need for sprinkler further enhance the scientific and technological content. The other hand, with urban residents the environmental awareness of the constant strengthening of the streets and highways clean is also increasingly focusing on. As the pavement cleaning equipment for sprinkler, and its importance should not be underestimated. Therefore, it’s necessary to design a safe, reliable, durable sprinkler, and the market prospects are bright, market potential is also very large.The design of the main tasks to add a set of pressure system that can draw and spray water on the original automobile chassis. One of the most important segments of the powertrain assembly score of the design.
