Abstract (en)
[origin: WO2005090694A1] The invention relates to a method and a device for damping the displacement of construction machines (1), in particular wheel loaders, comprising working equipment (1.2) that is driven by means of a hydraulic cylinder (1.4), a hydraulic source, a controlled valve (1.5) for supplying the hydraulic cylinder (1.4) with hydraulic fluid, a regulator unit (6) comprising control software, in addition to an acceleration sensor (2.1). The process for controlling the speed of the hydraulic cylinder (1.4) based on acceleration feedback comprises the following steps: a) detection of the acceleration signal; b) processing of the acceleration signal and determination of a control current (9) for the valve (1.5); c) supply of the hydraulic cylinder (1.4) with hydraulic fluid by means of the valve (1.5), in accordance with the control current (9).
