PLAIN THRUST BEARING MADE OF SYNTHETIC RESIN Russian patent published in 2013 - IPC F16C17/04 F16C33/20 B60G15/06 

FIELD: transport.

SUBSTANCE: plain thrust bearing (1) made of synthetic resin contains upper body (100) of synthetic resin, lower body (200) of synthetic resin and plain thrust bearing made of synthetic resin assembly (300), fitted between bodies (100) and (200). If to take radial length of body (100) from axis (o) to outer edge surface (303) of the assembly (300), located in lower ring cavity (205) as (r), and thickness of inner edge surface of upper ring plate section (102) as (t), on the upper surface (108) of body (100) there is ring flat surface (109) with circular outer edge, the radius (R) of which, if to take axis (o) of body (100) as centre of circumference, is equal to R=r±t. The thrust bearing (1) is located between lower surface of mounting element at the side of vehicle body and upper surface of spring upper socket, subtending to this lower surface. Due to this, the surface (109) only contacts with lower surface of mounting element at the side of vehicle body.

EFFECT: creation of plain thrust bearing which even under action of variable load such as tilt on mounting element at the side of vehicle body provides smooth operation of steering without interference of upper and lower bodies; higher operation efficiency due to possibility to maintain friction characteristics for a long time.
