Rack thruster comprising slide lining made of multi-layered material

摘要

A slide lining (9) for rack thruster (10) is dimensioned and shaped to come into contact with a steering rack (3) opposite to an operating pinion (4). The slide lining (9) is made of multi-layered material comprising a substrate layer intended to be bonded to a thruster body (8), an intermediate layer bonded to the substrate layer and an upper slide layer made of polymer composition with a low coefficient of friction. The intermediate layer forms raised structures which are distributed over the interface with the upper slide layer and are embedded in the said upper slide layer.
