Abstract
A hinge assembly with improved durability is provided with a first hinge arm with a first end portion, a second hinge arm with a second end portion, and a wear insert integrated with the second end portion. A gear segment of the first end portion is integrally formed from the first hinge arm and composed of a first material. The wear insert of the second end portion is distinctly formed from the second hinge arm. The wear insert is formed of a second material, while the second hinge arm is formed of the first material.
Claims19
A hinge assembly comprising:
- a first hinge arm having a first end portion;
- a second hinge arm having a second end portion;
- a wear insert arranged within a thickness of the second end portion;
- wherein the first end portion defines a gear segment formed from the first hinge arm and composed of a first material, and the wear insert of the second end portion is distinctly formed from the second hinge arm, the second hinge arm being composed of the first material and the wear insert being formed of a second material;
- wherein the gear segment defines a first set of teeth, and the wear insert defines a second set of teeth, the first and second sets of teeth arranged to cooperate with one another and form an interface.
A hinge assembly comprising:
- a first hinge arm having a first end portion;
- a second hinge arm having a second end portion;
- a wear insert integrated within a thickness of the second end portion;
- wherein the first end portion defines a gear segment integrally formed from the first hinge arm and composed of a first material, and the wear insert of the second end portion is distinctly formed from the second hinge arm, the second hinge arm being composed of the first material and the wear insert being formed of a second material;
- wherein the gear segment defines a first set of teeth, and the wear insert defines a second set of teeth, the first and second sets of teeth arranged to cooperate with one another and form an interface;
- wherein the second set of teeth form rounded caps at gear tips of the wear insert configured to cooperate with the first set of teeth.
A hinge assembly comprising:
- a first hinge arm having a first end portion;
- a second hinge arm having a second end portion;
- a wear insert integrated within a thickness of the second end portion;
- wherein the first end portion defines a gear segment integrally formed from the first hinge arm and composed of a first material, and the wear insert of the second end portion is distinctly formed from the second hinge arm, the second hinge arm being composed of the first material and the wear insert being formed of a second material;
- wherein the gear segment defines a first set of teeth and the wear insert defines a second set of teeth, the sets of teeth being arranged to cooperate with one another and form an interface;
- wherein the first end portion comprises a bushing coinciding with a first radius of the gear segment and defining a first wear surface, the bushing consisting of a thermoplastic material and forming an inner flange and an outer flange projecting beyond opposing sides of the first end portion.
