Title:
FRICTION MEMBER , ESPECIALLY BRAKE PLATE
Document Type and Number:
Japanese Patent JPS56127833
Kind Code:
A
Abstract:
The element is adapted to frictionally engage a movable tack e.g. a baking surface on a disc, ring, drum or band and comprises a support (13) to which is secured a friction lining (14), the support being formed with a gradually varying thickness (e.g. at e and E) so that the distribution R of the pressures P over the application face (18) of the lining conforms to a pre-selected distribution, for example and as shown a uniform distribution. The ability to vary the distribution of pressures over the application face enables the wear pattern of the lining to be controlled. A number of embodiments are disclosed, e.g. in Figs. 1-4 thickness of support (13) is lower at e where support is acted on by a piston (15). Variation in thickness of support may be formed by provision of ribs produced by corrugations. The ribs may have reinforcements. Patterns of ribs are disclosed. Details of composition of the support and lining are given- and production of the element by moulding.
