Description

安装于摩托车水冷发动机虹体上的水泵 技术领域 本发明属于发动机技术领域， 具体地说， 涉及安装于摩托车水冷发动机 上的水泵。 背景技术 图 1、 图 2分别是现有技术摩托车水冷发动机上水泵的结构示意图和安 装方式图， 从图中可看出水泵主要由水泵体 1、 水泵盖 2、 水泵轴 3、 叶轮 4 及水泵齿轮 5组成， 水泵安装在曲轴箱右盖 13上， 由曲轴驱动 （也有用机 油泵或离合器齿轮驱动的）， 水泵体 1与右箱盖 13之间的安装面垂直于水泵 轴 3的轴心线， 装配时连接螺栓 14将水泵盖 2、 水泵体 1与右箱盖 13—起 拉接固定， 由于水泵齿轮 5比水泵体 1外径大， 装配时要先将水泵安装到发 动机右箱盖上后， 再与右箱盖一起安装到发动机上， 安装不方便。 同样， 若 水泵出现故障需要维修时， 要先将水泵连同右箱盖一起拆下后， 再将水泵与 右箱盖分离开， 以进行相应的维修， 同样存在着不方便的问题。 另夕卜， 由于泵室 6的出水口与出水道 8彼此错位， 从泵室 6出来的水需 要两次改变方向才能流出水泵， 水流的流动阻力大， 进入发动机缸体的水流 速度低， 这样一方面使发动机的冷却效果差， 另一方面水泵因此不得不在高 转速情况下长期工作， 容易使水泵的寿命缩短， 可靠性降低。 发明内容 本发明的目的是为了克服上述不足，提供一种安装于发动机汽缸体上的 水泵， 使水泵的安装及维爹更方便。 为达到上述目的， 本发明提供的安装于摩托车水冷发动机缸体上的水 泵， 具有水泵体、 水泵盖、 水泵轴、 叶轮及水泵齿轮， 水泵盖安装在水泵体 端面上以形成泵室， 水泵的进、 出水道与泵室相连通， 所述水泵体上与发动 机缸体相配合的安装面平行于水泵轴的轴心线， 水泵体上用来与发动机缸体 相连的螺栓孔垂直于所述安装面。 本发明中的水泵安装在发动机虹体上， 水泵齿轮由正时链条驱动。 将容
