Title
(ZH) 可伸缩式履带底盘及具有该底盘的工程机械
Abstract
(ZH)

一种可伸缩式履带底盘及具有该底盘的工程机械,包括左履带架、右履带架、底座、至少一左伸缩油缸和右伸缩油缸,所述左伸缩油缸安装在底座与左履带架之间,所述右伸缩油缸安装在底座与右履带架之间,其特征在于:还包括至少一中空的左滑动横梁、至少一右滑动横梁,所述中空的左滑动横梁的一端与左履带架固定联结、右滑动横梁的一端与右履带架固定联结,所述底座上设有至少一中空滑座,所述中空的左滑动横梁的另一端从中空滑座的左端可移动地插入中空滑座之中,所述右滑动横梁的另一端从中空滑座的右端可移动地插入中空滑座和中空的左滑动横梁的中空部。可使工程机械的状态改变或转换更方便,整机行走和作业稳定性更高、更安全可靠。
