Abstract
A friction disk is provided. The friction disk includes a friction disk core, a first wear liner located over a first surface of the friction disk core, a second wear liner located over a second first surface of the friction disk core, a washer, and a rivet. The first wear liner and the second wear liner are coupled to the friction disk core via the rivet. The washer is configured to be positioned at a distal end of the rivet, such that, in response to the distal end of the rivet being upset forming an upset head, the upset head pushes against the washer thereby spreading a load of the upset head to at least one of the first wear liner or the second wear liner.
Claims20
A friction disk comprising:
- a friction disk core;
- a first wear liner located over a first surface of the friction disk core;
- a second wear liner located over a second surface of the friction disk core;
- a washer;
- and
- a rivet, wherein the first wear liner and the second wear liner are coupled to the friction disk core via the rivet and wherein the washer is configured to be positioned at a distal end of the rivet, such that, in response to the distal end of the rivet being upset forming an upset head, the upset head pushes against the washer thereby spreading a load of the upset head to at least one of the first wear liner or the second wear liner.
A multi-disk brake system comprising:
- a plurality of friction disks, each friction disk of the plurality of friction disks comprising:
- a friction disk core;
- a first wear liner located over a first surface of the friction disk core;
- a second wear liner located over a second surface of the friction disk core;
- a washer;
- and
- a rivet, wherein the first wear liner and the second wear liner are coupled to the friction disk core via the rivet and wherein the washer is configured to be positioned at a distal end of the rivet, such that, in response to the distal end of the rivet being upset forming an upset head, the upset head pushes against the washer thereby spreading a load of the upset head to at least one of the first wear liner or the second wear liner.
A friction disk comprising:
- a friction disk core;
- a first wear liner located over a first surface of the friction disk core;
- a second wear liner located over a second surface of the friction disk core opposite the first surface;
- a washer;
- and
- a rivet, wherein the first wear liner and the second wear liner are coupled to the friction disk core via the rivet and wherein the washer is positioned between an upset head of the rivet and one of the first wear liner or the second wear liner.
