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。

DESIGN OF GREEN SPRINKLER

(3 TONS OF WEIGHT)

TAKE POWER SECTOR OF GEARBOX AND PUMP DRIVE

ABSTRACT

Sprinkler as a Special Purpose Vehicle, plays an important role in spraying water and urban greening. 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. Power-take is covered through the transmission side will be the engine for part of the driving force came out to the pump and transfer its work to the device.

Key words : sprinkler，pressure systems，chassis，take power sector
