Abstract
A friction brake of a type which comprises at least one friction element and a counter-friction element frictionally engageable with the friction element. One of the friction and counter-friction elements is made of carbon and the other of the friction and counter-friction elements is comprised of at least two first and second portions both engageable simultaneously with such one of the friction and counter-friction elements during a braking operation. The first portion of such other of the friction and counter-friction elements is made of the same carbon material and the second portion thereof is made of ferrous material.
Claims7
A friction brake comprising:
- a friction element;
- and
- a counter-friction element frictionally engageable with the friction element, one of the friction and counter-friction elements being made of carbon material and comprising one of a friction pad or brake disk while the other of the friction and counter-friction elements comprises the other of the friction pad or the brake disk and comprises at least first and second portions both engageable simultaneously with said one of the friction and counter-friction elements during a braking operation, said first portion of such other of the friction and counter-friction elements being made of the same carbon material and the second portion thereof being made of ferrous material, whereby the ferrous material contacts the carbon material of said one of the friction and counter-friction elements during the braking operation.
