Abstract

Modern electro-mechanic-hydraulic systems are well suited to mobile equipment used in agriculture and road maintenance fields. This paper presents a system realized in the Hydraulic and Pneumatic Research Institute that contains a hydraulic energy generator group actuated by a thermal motor, and two rotary hydraulic motors. In order to control the hydraulic parameters, a system consisting of two proportional electro-hydraulic devices led by a dedicated electronic block is used. The electronics allow a programmed dependency between hydraulic parameters of the electro-hydraulic devices and the equipment speed. Also, with this system, the user can bill the substance quantity diffused (sand or salt) in comparison with the road surface
