Title: Innovations by David R DePiazza
Introduction
David R DePiazza is an accomplished inventor based in Aberdeen, NC (US). He has made significant contributions to the field of automotive engineering, particularly in clutch assembly technology. With a total of 2 patents to his name, DePiazza continues to push the boundaries of innovation in his industry.
Latest Patents
One of DePiazza's latest patents is the "Collapsing Clutch Retainer." This invention features a clutch assembly for motor vehicles that includes a retainer assembly with an upper and lower portion, which can be separated by a separating member. This design allows the retainer assembly to contract when moving toward a released position, providing additional clearance between the friction discs and flywheel without increasing the length of travel of the retainer assembly. The stationary guide member works in conjunction with the separating member to facilitate the expansion and contraction of the retainer assembly during clutch engagement and disengagement, ultimately minimizing clutch drag.
Another notable patent is the "Multi-Ratio Clutch." This improved clutch design features a distinct force ratio for holding compared to releasing. The innovation lies in positioning an abutment surface between a retainer and a diaphragm spring radially outward from the contact location between a release sleeve and the diaphragm spring. This configuration allows for a higher holding force while maintaining a lower release force, enhancing the overall performance of the clutch.
