  履帶的發(fā)明人是誰？

  這段話并沒有談及鏈和鏈輪是哪里來的，不能證明履帶是Holt發(fā)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". 
  
  這個是史料，請cat779兄過目，呵呵。

  履帶并不是霍爾特等人發(fā)明的，只是買的專利并加以應(yīng)用

  這里需要補(bǔ)充一下cat779，本杰明*霍爾特是卡特彼勒創(chuàng)始人之一，也是履帶式拖拉機(jī)的發(fā)明者。坦克之父與卡特彼勒創(chuàng)始人、履帶裝置的發(fā)明者聚首，確實有著很深遠(yuǎn)的意義。
