0引言机动三轮车是农村和城市中广泛用于运送各种物料的重要工具。为了实现其所装运物料的快速卸载,降低劳动强度,人们对其提出了增设自卸功能的要求。很多机动三轮车的动力源、变速器及倒挡器等都不具有动力输出接口,无法为自卸装置提供所需动力;并且由于其动力传动系统结构紧凑,再增设一套用于为自卸装置提供动力的动力源也不现实。另外,如果采用手动液压动力源的方式来卸载物料,也会存在卸载效率低、劳动强度大等问题。为此,笔者设计开发了一种具有自主知识产权、可
0 Introduction Motor tricycles are an important tool widely used to transport various materials in rural and urban areas. In order to achieve the rapid unloading of its shipment of materials and reduce labor intensity, people put forward its requirements for additional self-dumping function. Many motorized tricycle power sources, transmission and reverse gear, etc. do not have a power output interface, can not provide the necessary power for the dump device; and because of its compact power transmission system, and then add a set of power for the dump device The power source is not realistic. In addition, if the manual hydraulic power source way to unload the material, there will be unloading inefficient, labor-intensive and other issues. To this end, I designed and developed a proprietary intellectual property rights, may
