　　首先，因为两厢车一般都属于掀背式，后玻璃和后门是一体的，雨刷转轴装在后门玻璃下方金属门体上，当后门掀起时，不会影响雨刷器。

　　First, because the hatchback in general are hatchback, glass and the back door is one of the, the wiper shaft installed in the rear door glass below the metal door body, when the back door is lifted, will not affect the wiper.

　　而三厢车相对两厢车后面多了一个后备箱遮挡，没有地方装雨刷。可以想象，将雨刷转轴装在后背箱盖上，当箱盖打开时，琉璃却是不动的，那么雨刷器与琉璃的相对位置就会错位，所以不适合装。

　　But behind the three car relative hatchback car more than a trunk occlusion, no place to install the wiper. As you can imagine, wiper rotating shaft is installed in the trunk cover, when the box cover is opened, coloured glaze is not moving, then wiper and glazed relative position can become misaligned, so does not fit.

　　其次，这个是一个关于流体力学的问题，汽车在行驶时由于汽车的空间排挤了相应大小的空气，汽车在移动，在排开空气后空气由于流体的粘滞性质，无法快速的填充汽车所排开的空间。

　　Secondly, this is a question on fluid mechanics, car while driving due to space for cars crowding out the size of the corresponding air, car in mobile, in lined up in the air after the air due to the viscous properties and can't quickly filled cars lined up in space.

　　所以在车尾处形成真空，从而形成了涡流。由于涡流的影响，两厢车后风挡处比三厢车后风挡处容易形成更大的负压，也更容易卷起尘土污染后风挡玻璃，影响后视功能。而三厢车后轮转动所产生的污水几乎都被整个后备箱给遮挡了，不会造成污水卷上后玻璃窗的情况。

　　So at the end of the car to form a vacuum, so as to form a vortex. Due to the effect of eddy current, hatchback car windshield department than the car windscreen at easy to form negative pressure greater and more easily rolled up the dust pollution of the windshield, the impact of visual function. And three car rear wheel rotation generated by sewage are almost the entire trunk to block, will not cause the glass window of the sewage volume.

　　所以两厢车后风挡玻璃处一般都装有雨刷器，在雨天或后窗被污染时，开启雨刷器即可获得清晰的后方视野。但也不是绝对的，后掀背式三厢车也有装备后雨刷器的，只是不常见罢了。
