A friction system moistened by a lubricating oil comprising a pair of friction bodies movable relative to each other along a friction surface. At least one of the friction bodies contains a friction lining having a heat capacity ratio and a heat conductivity ratio which diminish perpendicularly away from the friction surface such that boundary friction and thermal elimination of the lubricating oil ensue at individual friction points of the friction surface, thereby disposing the seizing tendency of the friction bodies and obtaining constant coefficients of friction and low rates of wear.

Friction system

The friction surfaces (4) of two essentially annular friction elements (1) which, through relative motion, can be arranged to transmit torque, are each approximately formed like the surface of a spherical layer whose center (M) is situated on the axis (5) of the annular frictional elements (1) outside the bottom plane of the spherical layer. This is a simple way to ensure a whole-surface, interlocking contact and a good friction performance over a large number of cycles even during a minor tilt of the two cooperating friction surfaces (4).
