Abstract
A friction disk includes a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface. The friction disk further includes a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon of each wear liner segment being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner.
Claims18
A disk brake system comprising:
- an inner spline and an outer spline;
- a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface;
- and
- a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon of each wear liner segment being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner,
- wherein the two wear liner segments are configured to interface with the inner spline and the outer spline, the interface between the inner spline, the outer spline, and the two wear liner segments resisting radial movement of the two wear liner segments.
A disk brake system comprising:
- an inner spline and an outer spline;
- a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface;
- and
- a first wear liner having a first wear liner segment and a second wear liner segment each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon of each wear liner segment being configured to be received by a corresponding mortise of the multiple mortises to couple the first wear liner segment and the second wear liner segment to the friction disk core without use of fasteners to form an annular liner,
- wherein the two wear liner segments are configured to interface with the inner spline and the outer spline, the interface between the inner spline, the outer spline, and the two wear liner segments resisting radial movement of the two wear liner segments.
A multi-disk brake system comprising:
- an inner spline and an outer spline;
- a plurality of rotors configured to rotate about an axis;
- and
- a plurality of stators configured to remain stationary relative to the axis,
- wherein at least one of the plurality of rotors or the plurality of stators includes:
- a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, and
- a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon of each wear liner segment being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner,
- wherein the two wear liner segments are configured to interface with the inner spline and the outer spline, the interface between the inner spline, the outer spline, and the two wear liner segments resisting radial movement of the two wear liner segments.
