Displacement management system for delimbing head
收藏资源简介:
The present invention relates to a system for driving a mobile element, comprising at least one drive device (A, B) comprising: - a main motor (M11, M12), configured to be connected to the first supply line (10), - a multi-displacement secondary motor (M21, M22), configured to be connected to the second supply line (12) and comprising two half-motors (V1, V2) corresponding to two displacement levels (V1 , V1 + V2), in which the first half-motor (V1) is coupled in series with the main motor (M11, M12) via a serial line (L10A, L10B), - a vacuum valve (20A, 20B) controlled by the using a control line (25A, 25B) and configured to activate or deactivate the second half-motor (V2), - an additional supply line (L11A, L11B) configured to be connected to the first supply line (10) and connected to the second half-motor (V2), in which the vacuum valve (20A, 20B, 20) is also controlled using a feedback controlling the steering line (25A, 25B, 25), said feedback being performed by a feedback line (27A, 27B, 27) sampling from the additional supply line (L11A, L11B, L11).
