工程自卸车液压举升系统按照液压缸在车厢上布置位置的不同可分为前置式(图1(a))、腹置式(图1(b))和侧置式(图1(c)),也相应称为前顶式、中顶式和侧顶式。侧置式液压举升系统是从2002年起由制造商根据用户的使用要求开发生产并推向市场的。该系统由液压齿轮泵、液压缸、液压控制阀(限位阀)、液压油箱等液压基本元件组成。其中,液压缸采用的是单作用、多节伸缩式油缸,并布置在车厢的两侧(宽度方向)。本文就近几年广泛兴起的侧置式液压举升系统进行简要分析。
The hydraulic lifting system of the engineering dump truck can be divided into the front type (FIG. 1 (a)), the belly type (FIG. 1 (b)) and the side type (FIG. 1 (c)) according to the arrangement position of the hydraulic cylinder in the car. , Also known as the top of the top, top-style and side-top type. Lateral hydraulic lifting system from 2002 onwards by the manufacturer according to the user’s requirements to develop and produce the market. The system consists of hydraulic gear pump, hydraulic cylinder, hydraulic control valve (limit valve), hydraulic tank and other hydraulic basic components. Among them, the hydraulic cylinder is a single-acting, multi-section telescopic cylinder, and arranged on both sides of the car (width direction). In this paper, the recent rise of a wide range of side-mounted hydraulic lifting system for a brief analysis.
