工程机械变速器发展历程
工程机械传动系的发展历程与主机的发展是同步的。以装载机为例，其传动系皆从拖拉机、汽车传动系演变而来。20世纪60年代初，装载机的特征结构形式已基本定型．其传动系的型式格局也随之框定，小型机多采用机械式传动，中型和大型装载机采用动力换挡（液力机械或全液压传动），超大型装载机（矿山开挖）采用电拖动及电动轮方式（如美国马拉松公司的产品）。
The developing course of construction machinery contains transmis- sion system's research.For example,wheel-loader's transmission sys- tem was evolved from tractors and cars.At the beginning of 1960s, wheel-loaders had built up their owner's framework,at the same time transmission system finalized its design.Compact wheel-loaders adopt mechanical transmissions,while medium and large wheel-loaders in- troduce hydraulic transmissions,and huge wheel-loaders always match electric transmissions.
