Description
- This application is a continuation of and claims priority to U.S. patent application Ser. No. 14/817,833 filed on Aug. 4, 2015, the entirety of which is incorporated herein by reference.
- The invention generally relates to vehicle brakes, and more specifically to an improved vehicle brake rotor, and a process for making same.
- Vehicle brake rotors are known and typically include a friction ring or disc to which is fastened a hub used to connect the ring to a vehicle wheel. As is well known, friction rings have opposing friction surfaces for engagement by brake pads mounted in vehicle calipers such that each of two pads engage a corresponding surface of the friction ring under driver control to stop the vehicle. The friction ring of the vehicle brake rotor rotates about a central axis, coincident with the rotational axis of the wheel to which it is attached.
- To reduce vehicle brake rotor weight, and improve the vehicle brake rotor's heat dissipation efficiency, brake rotors made of two materials have become both more popular and common, particularly among high-end vehicles. Friction rings are typically cast from a ferrous material, such as cast or grey iron. The friction rings are then machined in multiple operations to shape the rotor and form an inner mounting section and the friction surfaces. The friction surfaces of the rotor are also machined to a predetermined tolerance range.
- The hub of a vehicle brake rotor is typically cast from metallic materials such as aluminum. A conventional hub further includes a centrally located bore, and a plurality of equally spaced fastener mounting holes formed circumferentially in a mounting surface around the bore. Hubs are connected to the disc body, usually with a plurality of fasteners such as rivets, or threaded fasteners, such as screws. By connecting the hub to the friction ring, fasteners keep the hub and friction ring together. As a result, fasteners aid in movement of the vehicle brake rotor.
- To accurately assemble the brake rotors made of two materials, complicated equipment is needed. Due to the high level of skill needed to operate such complicated equipment, the costs of manufacturing the two material vehicle brake rotor with fasteners are high.
- Another drawback of conventional bi-metallic brake rotors is that a hub made of lighter materials has a higher expansion rate than the friction ring made of cast iron. When the vehicle brake rotor undergoes high temperature conditions, expansion of the hub and the friction ring will occur. Such expansion will further occur when the vehicle brake rotor and friction rings engage. There is a concern that multi-component brake rotors will be subject to shorter operational life due to the different expansion and contraction properties of the materials used in production. Thus, there is a need for an improved technique for manufacturing vehicle brake rotors.
- The above-listed needs and drawbacks are addressed by an improved vehicle brake rotor designed to be constructed so that the friction ring and the hub are connected to each other without fasteners. Vehicle brake rotors made according to the present process are simpler and less expensive to manufacture. Further, vehicle brake rotors without fasteners are more reliable, and have a longer lifespan, because the possibilities of the fasteners touching the friction ring are reduced. A method for making the brake rotor without fasteners, and a brake rotor made by such a process are thus disclosed as a solution to the problems described above.
- The process works by first manufacturing a friction ring conventionally made of gray iron, or other heavy metal. In a preferred embodiment, there are two of the manufactured friction rings, each having an edge and a face, and being connected by conventional materials used to join two friction rings. One of the faces of the friction rings has an annular flange projecting axially relative to the face of the friction ring. On an exterior surface of the annular flange, a preferably equally distributed plurality of spaced lugs project radially from the annular flange. An interior surface of the annular flange has an interior groove or flat surface.
- The present brake rotor features the hub being integrally joined to the friction ring. The friction ring is placed into a cavity corresponding of an embed casting mold. Once this is accomplished, a molten material conventional in embed casting, such as aluminum, is poured into the cavity, and covers the lugs and the flange of the friction ring. As the molten aluminum cools, the hub is formed and is integrally joined to the friction ring. Once this is accomplished, the positive and negative chambers of the embed casting mold are removed, and the combined friction ring and hub are withdrawn from the mold. Next, an exterior peripheral edge of the hub is manufactured or machined, such that outermost ends of lugs on the annular flange are visible.
- More specifically, a method of making a vehicle brake rotor is provided, including, manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange. A hub is manufactured with a plurality of recesses integrally upon the friction ring. Next, the hub is manufactured or machined so that outermost ends of the lugs are visible from an exterior of the hub.
- In another embodiment, a vehicle brake rotor is provided, including a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring that defines the opening and a plurality of spaced lugs projecting radially from the flange. A hub is provided with a plurality of recesses matingly engaging the lugs, an endcap covering the opening of the hub, and the hub is integrally joined to the friction ring. After machining or manufacturing the hub, outermost ends of the lugs of the brake rotor are visible from an exterior of the hub.
- In yet another embodiment, a vehicle brake rotor manufactured by a process is provided, including the steps of manufacturing a friction ring with an opening, an annular flange projecting axially relative to a face of the friction ring, and a plurality of spaced lugs projecting radially from the flange. Manufacturing a hub with a plurality of recesses upon the friction ring, each recess engaging a corresponding lug, and joining the hub integrally to the friction ring. The hub is then machined or manufactured so that outermost ends of the lugs are visible.

On theface 16 of thefriction ring 12 a are an axially projectingannular flange 20, and anopening 22 of the friction ring defined by theannular flange 20. Projecting radially from the axially projectingannular flange 20 is a plurality oflugs 24. Theannular flange 20 also includes aninterior wall 26. Ahub 28 is integrally joined to theflange 20, preferably by embed casting. In the preferred embodiment, the hub is composed of aluminum or other metals. On top of thehub 28 is anendcap 30. - Casting the
hub 28 upon thefriction ring 12 produces a plurality ofrecesses 32, which matingly engage thelugs 24 projecting radially from theannular flange 20. Thehub 28 also engages theannular flange 20 via aninterior groove 34. Thelugs 24 are concentric with therecesses 32 onhub 28, and are preferably spaced equidistantly. While in the preferred embodiment thelugs 24 are generally cylindrical in shape, other shapes are contemplated, including various polygonal shapes (when viewed in transverse cross-section). As seen inFIG. 3 , after thehub 28 is cast, thelugs 24 are completely covered by the hub. - The
rotor 10 is mounted to the vehicle wheel using mountingholes 36 in theendcap 30, and acentral opening 38 engages an axle shaft (not shown). Thevehicle brake rotor 10 is mounted to a wheel of, for example, an automotive vehicle on the inboard side of the wheel, with respect to the assembled vehicle, for stopping the rotation of the wheel in operation of the vehicle.

As thehub 28 is joined integrally to thefriction ring 12 theendcap 30 on the hub partially covers theopening 22. As seen inFIG. 3 , thelugs 24 are completely covered by thehub 28. - Referring now to
FIG. 6 , in the preferred embodiment of the presentvehicle brake rotor 10, thefriction ring 12 and thehub 28 are integrally joined by embed casting, using a mold generally designated 40, including twomating portions friction ring 12 is cast and suitably machined, it is placed into a correspondingcavity 42 of themold 40. Amolten material 44, typically aluminum, or another suitable alloy, is then poured into achamber 46 of theembed casting mold 40. As themolten material 44 flows down thechamber 46, it forms thehub 28, The high temperatures of themolten material 44 cause thefriction ring 12 to expand, andinterior groove 34 of the hub matingly engages theflange 20. Also, thelugs 24 matingly engage therecesses 32, located in askirt 48 of thehub 28. - After the
molten material 44 cools, thefriction ring 12 and thehub 28 are integrally joined to each other, and thelugs 24 are matingly received in therecesses 32. After cooling, the joinedhub 28 and friction ring is then machined so that outermost ends 50 of thelugs 24 are visible from an exterior of the rotor 10 (FIGS. 1 and 2 ). While in the preferred embodiment, the ends 50 are circular, other shapes are contemplated, depending on the cross-sectional geometry of thelugs 24 as discussed above. - Referring now to
FIG. 7 , an alternate embodiment of the presentvehicle brake rotor 10 is generally designated 60. Components shared with therotor 10 are designated with identical reference numbers.
