The invention provides an electro-hydraulic integrated electric cylinder, belongs to the technical field of electric cylinder application, and mainly adopts an integrated design of a hydraulic motor, a pump, a pipe valve and an oil tank. Comprising a servo motor (or an automobile power take-off device), a coupler, a hydraulic pump, a miniature closed pressure oil tank, a hydraulic motor, a functional valve block, a one-way valve, a hydraulic control one-way valve, an overflow valve, a miniature closed pressure oil tank and an electric cylinder body. The overall size of the electric cylinder is reduced by reducing the size of a power source of the electric cylinder, the problems that a traditional electric cylinder is driven by a high-power motor, so that the overall appearance size is large, and the production cost is high are solved, the overall structure is more compact, and the electric cylinder is suitable for field heavy-load working conditions of engineering trucks, good in stability and suitable for popularization.
本发明提供了一种电液一体化电动缸,属于电动缸应用技术领域,主要采用液压马达+泵+管阀+油箱一体化设计,包括伺服电机(或汽车取力装置)、联轴器、液压泵、微型闭式压力油箱、液压马达、功能阀块、单向阀、液控单向阀、溢流阀、微型闭式压力油箱、电动缸缸体,采用工程车取力装置为电动缸提供动力,实现电动缸推杆的伸出与缩回,通过缩减电动缸动力来源体积的方式,缩小电动缸整体体积,解决了传统电动缸采用大功率电机驱动导致整体外形尺寸大、生产成本高的问题,整体结构更加紧凑,适用于工程车野外重载工况,稳定性好,适合推广。
