【摘要】 介绍了EBZ-132SH型掘进机行走机构的组成及工作原理,并对行走机构的5个部分液压系统进行设计和说明,在此基础上提出用电液比例控制阀做先导阀来控制行走马达从而达到对掘进机行走方向的控制。更多还原

【Abstract】 Briefly introduces the composition and working principle of the walking mechanism of EBZ-132SH roadheader.Futhermore,the part of its hydraulic system has been designed and explanated.Base on these we suggest that use electro-hydraulic proportional control valve as aguide valve to control walking motor.So that can use this system to control the roadheader walking direction.更多还原
