Title: The Innovations of Erich Erhart
Introduction
Erich Erhart is a notable inventor based in Graz/St. Peter, Austria. He has made significant contributions to the field of automotive technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Erhart's latest patents is a differential gear and control system for motor vehicles with a single driven axle and at least one undriven axle. This system includes a differential gear and a differential lock, which is controlled based on the vehicle's speed. The design aims to enhance traction during vehicle start-up while ensuring that the handling remains unaffected by the locking of the differential gear. The differential lock exerts a restraining torque that decreases as the vehicle's speed increases from zero to a predetermined level.
Another significant patent involves a process for providing an air-filled space with a predetermined volume in a liquid-containing liquid friction coupling. This process requires minimal manipulation and can be executed quickly. It involves forcing equal quantities of air into both the liquid friction coupling and a pressure-tight reference vessel. The pressure difference is then measured, and adjustments are made by adding or removing liquid from the friction coupling to balance the pressures.
