Claims35
A wet brake assembly for braking a wheel, comprising:
- a brake anchor, including:
- a brake anchor annular portion,
- a brake anchor second annular portion, and
- a plurality of brake anchor splines on the brake anchor first annular portion, said splines being oriented in an axial direction.
A wheel spindle assembly for mounting a wheel and brake assembly, comprising a large diameter portion having a plurality of wheel spindle splines, said splines being oriented in an axial direction, on an outside circumferential surface of the large diameter portion for coupling with the brake assembly.
A combination brake and wheel spindle, comprising:
- a wheel spindle, including a large diameter portion having a plurality of wheel spindle splines on an outside circumferential surface of the large diameter portion;
- and
- a wet brake assembly, including:
- a brake anchor, including:
- a brake anchor inboard annular portion on an inboard side of the brake anchor,
- a brake anchor outboard annular portion on an outboard side of the brake anchor, and
- a plurality of brake anchor splines on the brake anchor inboard annular portion;
- wherein the wet brake assembly is axially mounted on the wheel spindle;
- and
- wherein the plurality of wheel spindle splines are meshed with the plurality of brake anchor splines to form a mechanical spline joint so that the brake anchor is non-rotatably coupled to the wheel spindle.
A combination brake and wheel spindle, comprising:
- a wheel spindle, including a large diameter portion;
- a wet brake assembly, including:
- a brake anchor, including:
- a brake anchor inboard annular portion on an inboard side of the brake anchor,
- a brake anchor outboard annular portion on an outboard side of the brake anchor;
- and
- means for mounting the brake anchor to the wheel spindle by using a plurality of splines to form a mechanical spline joint so that the brake anchor is non-rotatably coupled to the wheel spindle.
An off-highway vehicle, comprising:
- wheels that support the off-highway vehicle for rolling engagement with a ground,
- a wheel spindle rotatably supporting at least one of the wheels, the wheel spindle including wheel spindle splines on outside circumferential surface of the wheel spindle;
- a wet brake assembly, including a brake anchor having brake anchor splines on an inside circumferential surface of the brake anchor;
- and
- a spline joint formed by a mesh between the wheel spindle splines and the brake anchor splines so that the wet brake assembly is non-rotatably coupled to the wheel spindle.
