Abstract |
AB |
[EN] To provide a crawler chain for tracked vehicles, especially chain-driven construction vehicles, consisting of steel chain bushes, bolts and links, in which the inside ends of the links are pressed on the bush, the outside ends are pressed on the ends of the bolt projecting beyond the bush and the bolt passes through the bush, which is less prone to wear or is subject to less wear than prior art crawler chains, it is proposed that the bush (1) consists of hard metal, fibre composites, engineering ceramics and/or preferably ceramic-ceramic composites based on Si3N4 (silicon nitrite) with less than 15 wt. % sintering additive. |
