Hydraulic rack steering system |
摘要 |
A hydraulic rack steering system is provided with a unitary seal assembly around a piston rod which is a composite of compressible toroidal gaskets having an intermediate pre-stressing ring constructed and arranged to radially stress a plastic sealing ring against a piston rod. Thus, there is a sliding sealed relationship established between the piston rod and a composite sealing assembly secured within the servocylinder. The composite sealing ring assembly is carried in an assembly housing with the components locked in place therein by a closure ring press fitted into the housing. The cover ring is spaced from the composite sealing members in order to permit clearance for the piston rod to follow bending of a rack with which the piston rod is integral and wherein the rack is subjected to bending effected by steering stress.
