Hydraulic steering rack system

摘要

In a steering rack system whose servomotor (2) has non-balanced cylinder chambers (13, 16), that is to say the ratio of the piston faces to one another is approximately 1:2, the flow occurs from the servopump (4) to the control valve (3) via a pressure line (17) directly into the small cylinder chamber (13) and from there via a channel (18) into the rotatable valve housing (19) of the control valve (3). As a result, the compression medium passes by a portion of the toothed rack (8) and the pinion (7). As a result, the entire steering system, and in particular the rack seal (56), heats up uniformly and quickly. <IMAGE>
