目前国内轮式联合收割机主要还是采用机械式无极变速胶带传动,在2011年左右开始有主机厂家进行静液压驱动收割机的开发与市场验证,2013年后逐步实现小批量的销售。静液压行走驱动系统从开始主要应用于玉米收割机,到现在已经扩展到小麦机、青储机、多功能谷物联合收割机等轮式收割机。 At present, the domestic wheeled combine harvester mainly adopts the mechanical stepless speed change belt drive. In the beginning of 2011, there are host manufacturers for hydrostatic drive harvester development and market verification, and gradually realize the sales in small batch after 2013. The hydrostatic travel drive system has been mainly used in corn harvesters since its inception and has now been extended to wheeled harvesters such as wheat machines, green storage machines and multi-functional grain harvesters.
