On the other hand, along with the rapid urbanization process, various accidents are increased rapidly, and the serious loss of lives and properties of people is caused. Taking 2013 as an example, the number of deaths caused by accident disasters in China reaches 6.9 thousands of people, and the direct economic loss is 5808.4 hundred million yuan, which accounts for about 1 percent of GDP. The disasters and accidents have the characteristics of diversity, complexity and the like, and great difficulty is brought to rescue and reconstruction after the disasters. However, the disaster emergency rescue equipment in China has the defects of serious technical level lag, single function and low specialization degree, so that the rescue is not timely and the efficiency is low. Especially, the mobility of emergency rescue equipment is seriously restricted by complicated topographic and geological conditions after disasters, and precious rescue time is lost. The high-speed track assembly can remarkably improve the capacity of the emergency rescue vehicle for dealing with complex geological and terrain conditions after disasters such as muddy and soft ground, and improve the efficiency of emergency rescue.

The high-speed triangular rubber track assembly can be installed in a matched manner with a wheeled vehicle, so that the maneuvering performance of the vehicle is greatly improved, and the high-speed triangular rubber track assembly is widely applied to emergency rescue, geological exploration, snow transportation, military equipment and the like. The meshing error between the driving teeth of the high-speed triangular rubber crawler assembly and the rubber crawler teeth can cause the abrasion of the rubber crawler teeth, thereby reducing the service life of the rubber crawler.

The driving teeth of the existing rubber track are mostly cylindrical driving teeth and are mainly used for medium and low speed rubber tracks. Compared with the prior art of high-speed rubber tracks, the method has the following defects:

(2) The processing is comparatively complicated, and drive tooth both ends need ensure coaxial, and the machining precision is higher. Meanwhile, the arcs of the two side plates of the driving wheel are inconvenient to drill (in the machining process, a drill bit is under eccentric load and easy to deflect), linear cutting machining is needed, and the machining speed is low. The small bolts at the two ends are easy to loosen and need to be matched with a lubricating shaft sleeve.
