这段话并没有谈及链和链轮是哪里来的,不能证明履带是Holt发明的

Holt was an inventor and manufacturer. His family's firm specialized in manufacturing combined harvesters. Their first was sold in 1886 and their first steam traction engine was sold in 1890. His combined harvesters used chains and sprockets to transfer power from the steam engine to the moving parts of the harvester. Chains and sprockets were the fundamentals of a working "crawler". 这个是史料,请cat779兄过目,呵呵。

履带并不是霍尔特等人发明的,只是买的专利并加以应用

这里需要补充一下cat779,本杰明*霍尔特是卡特彼勒创始人之一,也是履带式拖拉机的发明者。坦克之父与卡特彼勒创始人、履带装置的发明者聚首,确实有着很深远的意义。
