我国工程机械“双变”供应渠道具有多样性,即“双变”的生产厂家既有专业厂又有主机厂;除了为国内整机配套以外,也逐步开始为国外产品配套(主要是变矩器)作为工程机械的核心部件之一,传动部件是整机的中流砥柱,而由液力变矩器和变速器构成的“双变”组合更是其中的核心。与液压元件不同,我国工程机械“双变”供应渠道具有多样性,即“双变”的生产厂家既有专业厂
China’s construction machinery “double change ” has a variety of supply channels, that is, “double change ” manufacturers have both professional factories and OEMs; in addition to supporting the domestic machine, but also gradually began to support foreign products ( Mainly torque converter) as one of the core components of construction machinery, transmission components are the mainstay of the whole machine, and the “double change” combination of torque converter and transmission is the core. Different from hydraulic components, China’s construction machinery “double change ” has a variety of supply channels, that is, “double change ” manufacturers have both professional factory
