折叠式叉车行走液压系统分析

Analysis of Driving Hydraulic System in Folding Forklift

折叠式叉车是一种能够用带蓬杆、蓬布的运输车和普通厢式运输车运输的装卸搬运装备。为适应该型叉车结构紧凑的要求,其行走系统采用了静压传动系统。设计了两挡车速控制回路、行驶防滑控制回路、比例压力控制回路等,以满足该型叉车不同路面行驶要求。

Folding forklift is a handling equipment which can be transported by transport vehicle with tarpaulin and tarpaulin rodand by ordinary van. The hydrostatic transmission system adopted in driving system was determined by the compact structure of the fork-lift truck. The two speed control loop, the driving slip control loop and the proportional pressure control loop were designed to meet thedriving requirements of different road surfaces.
