Abstract
The brake block has incorporated means such as strain gauges for measuring dynamic brake forces in two normal coordinate directions.
Claims2
Dynamic brake force measuring means comprising in combination, a brake mechanism including a braking block and a braking friction material for contacting a rotating member preferably a railway wheel, a measuring part immovably affixed to said braking block at selected positions with said measuring part having at least two elastically deformable sections extending from the affixed positions responsive to deform respectively to brake forces transmitted thereto by said braking friction material through said braking block in different coordinate directions signifying radial and tangential brake forces, separate strain gauge means affixed respectively to said two deformable sections for reading out separately the forces appearing in said different coordinate directions dynamically during the braking operation thereby to derive separate radial and tangential brake forces at different speeds and loads and braking forces, and directional force transmitting members respectively bearing on both said two deformable sections and braking block in said coordinate directions to transmit dynamic braking forces between said braking block
