WANG WEI / JIN LIANG / MIAO YUANMIN / REN FULI

The invention discloses a special chassis with a gate-type transmission system for a snow sweeper. The special chassis comprises an engine, a transmission, a plurality of transmission shafts, a snow removing mechanism, a transfer case, a front axle and a rear axle. The engine is installed below a cab of a whole vehicle body. The transmission is mounted at an output end of the engine; the transmission shafts comprise a transmission shaft A, a transmission shaft B, a transmission shaft C, a transmission shaft D and a transmission shaft E; the snow removing mechanism is mounted in the middle of the vehicle body; included angles between the transmission shafts B and E and a horizontal plane are reduced compared with that of an existing transmission shaft; abrasion of the transfer case and an axle internal gear is decreased so that a failure rate is greatly reduced, transmission stability is improved, and meanwhile, a noise is reduced; and due to a fact that the included angle between the transmission shaft B and the transmission shaft E is reduced to be smaller than 7 degrees, a height of the main frame and the height of the cab of the vehicle body are decreased, the mass center of thewhole vehicle is reduced, running stability of the vehicle is improved, and meanwhile workers can get on and off the vehicle more conveniently.

本发明公开了一种具有门式传动系统的除雪车专用底盘，包括发动机、变速器、若干传动轴、除雪机构、分动箱以及前桥和后桥，所述发动机安装于整个车身的驾驶室下方位置，且变速器安装于发动机的输出端，所述传动轴包括传动轴A、传动轴B、传动轴C、传动轴D以及传动轴E，所述除雪机构安装于车身中部的位置，本发明设置的传动轴B和E与水平面的夹角较现有的传动轴降低，分动箱和车桥内齿轮磨损降低，从而使其故障率大大降低，提高了传动的稳定性，同时噪音降低，由于传动轴B和E的夹角降到7度以下，车身的主车架和驾驶室的高度得以降低，使整车质心降低，车辆行驶稳定性提高，同时也更加方便工作人员上下车工作。
