With a total of 3 patents to his name, Hartford's work showcases his innovative approach to improving vehicle safety and performance.
Latest Patents
One of Hartford's notable patents is for an improved vehicle disc brake rotor featuring a unique vented design. This rotor includes a pair of brake friction plates that are maintained in a spaced relationship by a plurality of radially extending fins. The friction plates are tapered radially, increasing their cross-sectional thickness at the outer end, which enhances heat capacity and stiffness. Additionally, the design incorporates a separate radially extending cooling air passageway between each pair of fins, improving cooling efficiency by increasing the velocity of cooling air as it flows through the passageway.
Another significant patent by Hartford involves a disc brake rotor produced through a machining method. This rotor features generally parallel inner and outer machined friction faces that are designed to be frictionally engaged by brake pads. Each friction face includes a spiral machining groove that operates to produce forces on the brake pads, minimizing the net radial force when engaged. This innovative design contributes to more effective braking performance.
