Latest Patents
Grell's latest patents include a friction clutch arrangement designed to control a clutch friction disk that is rotationally mounted on a transmission shaft. This arrangement allows the clutch to be locked between two components and features a clutch actuating device. The device includes a slave device adjacent to the clutch, a master device located remotely, and a force transmission system connecting the two. The slave device is equipped with an annular housing that contains a movable piston, which engages with the clutch friction disk. A piston sensor within the housing extension enables the determination of the piston’s position, independent of external influences such as vibrations or dirt.
Another patent by Grell also focuses on a friction clutch arrangement for motor vehicles. This design includes a fixed cylinder made of nonferromagnetic conductive material, a movable piston, and a variable inductance travel sensor. This sensor extends parallel to the piston’s path, allowing for accurate position determination in the slave cylinder, again independent of external factors.
