行走机构是矿山机器一个重要的部件,它和一般工程机械有许多共同点。一般看来,矿山机械中,目前行走机构的驱动型式,无疑液力机械传动占有主导的地位,其驱动系统是由液力变矩器加上动力换挡变速箱及机械传动所组成。十几年前,液压驱动的行走机构首先出现在挖掘机上,以后逐渐推广到堆土机和装载 Walking mechanism is an important part of the mining machine, which has much in common with the general construction machinery. In general, mining machinery, the current driving body driving type, no doubt hydraulic machinery drive occupies a leading position, the drive system is composed of torque converter with power shift transmission and mechanical transmission. A dozen years ago, the hydraulic-driven running gear first appeared on the excavator, and later gradually extended to the grader and loading
