Title: Innovations by Robert Marion in Automotive Transmission Systems
Introduction
Robert Marion is a notable inventor based in Lindau, Germany. He has made significant contributions to the field of automotive transmission systems, holding 2 patents that showcase his innovative approach to hydraulic control mechanisms.
Latest Patents
One of his latest patents is a hydraulic gear-shift control for automotive transmission systems. This invention aims to control the changeover between different speed ratios in an automotive transmission using hydraulically actuated clutches and brakes. The system employs a 1-2 shift valve and a 2-3 shift valve that respond to speed-dependent fluid pressure, which is counterbalanced by a load-dependent fluid pressure generated by a throttle valve. This mechanism is designed to enhance the efficiency and responsiveness of vehicle acceleration.
Another significant patent by Marion is a hydraulic actuating system for a pair of concurrently operating clutches. This system is designed for automotive transmissions and operates in an intermediate-speed position. It utilizes a slide valve to control the fluid flow to two hydraulic brakes, ensuring that one brake remains actuated during upshifts, while the other is released. This innovative design improves the overall performance of the transmission system.
