Abstract
The utility model relates to the technical field of steering engine pressing blocks, in particular to an improved pressing block gasket structure which comprises a pressing block and a gasket, a cylindrical pin column, a fan-shaped axial reinforcing rib and a fan-shaped circumferential reinforcing rib are arranged on the back face of the gasket, and a circumferential oil storage groove and an axial oil storage groove are formed in the surface of the gasket. Compared with the prior art, the fan-shaped reinforcing ribs in the circumferential direction and the axial direction are adopted, the axial bearing capacity and the circumferential bearing capacity are considered, meanwhile, the bearing capacity is increased, and the lining is prevented from being twisted; the axial oil storage grooves and the oil storage holes are added, so that the contact area between the lining and the rack is reduced, the oil storage space is increased, the friction is reduced, and the noise risk is reduced; the oil storage hole is formed in the intersection of the axial oil storage groove and the circumferential oil storage groove, the number of contact points of the lining and the rack is changed into two, the positive pressure borne by the lining is reduced, the gap between the pressing blocks is reduced accordingly, the bearing capacity of the lining is improved, meshing of the gear and the rack is smoother, the clamping stagnation phenomenon is not prone to occurring, and the driving feeling of a client side is improved.
