The invention discloses a special sealing device for a driving shaft of a high-speed wheel type amphibious vehicle, which achieves the purpose of the invention by combining four sealing rings with different lip forms, an oil lubrication mode and a grease lubrication mode as well as a special muddy water prevention and dust prevention structure and a lubricating oil forced circulation heat dissipation and cooling mode. The key technology of driving shaft sealing of the high-speed wheel type amphibious vehicle is broken through. The device can adapt to complex working conditions of vehicle running, meets the sealing requirement and the safety requirement of land and water high-speed running, has long enough service life and is convenient to repair and maintain.
本发明公开了一种专用的高速轮式两栖车辆驱动轴密封装置,本发明通过组合四种不同唇口形式的密封圈和油、脂两种润滑模式,加上特殊的防泥水、防尘结构和润滑油强制循环散热冷却方式,达成了发明目的,突破了高速轮式两栖车辆驱动轴密封的关键技术。该装置能够适应车辆运行的复杂工况,满足水陆高速行驶的密封要求和安全性要求,具有足够长的使用寿命且便于维修保养。
