Title: Innovations by Jeffrey J McFarland
Introduction
Jeffrey J McFarland is an accomplished inventor based in Commerce, MI (US). He has made significant contributions to the field of automotive technology, particularly in the development of innovative clutch systems and hydraulic fillers for transmissions. With a total of two patents to his name, McFarland's work exemplifies the intersection of engineering and practical application.
Latest Patents
One of McFarland's latest patents is for a formed friction plate for wet friction clutches. This invention features a friction clutch pack that exhibits improved high-speed stability. It includes a first plurality of friction plates or discs, which have friction material on both faces, interleaved with a second plurality of thicker reaction plates or discs. The friction plates are designed with a formed core plate that has multiple obliquely oriented or angularly offset sinusoidal waves. Male splines around the periphery of each friction plate engage complementary splines on a cylindrical housing. The reaction plates are flat and thicker than the friction plates, featuring female splines around an inner opening that engage complementary splines on a shaft or quill.
Another notable patent by McFarland is a hydraulic filler for a motor vehicle transmission. This hydraulic fluid filler includes a set of holes through which respective springs of a spring pack extend. The filler is generally positioned adjacent to a single retainer ring or between two retainer rings associated with the spring pack. In some implementations, the filler floats between the two retainer rings, while in others, it is securely attached to one or both of the retainer rings. This invention effectively reduces the volume of one of two cavities, chambers, or cylinders positioned on opposite sides of a piston that selectively interacts with a clutch assembly to engage or disengage the clutch assembly.
