Title: Innovations by Robert Schaffernak
Introduction
Robert Schaffernak is an accomplished inventor based in Weiz, Austria. He holds two patents that showcase his expertise in hydraulic and mechanical systems. His innovative designs contribute significantly to advancements in automotive technology.
Latest Patents
One of Schaffernak's latest patents is a speed differential-dependent hydraulic clutch with a control valve. This invention features a drive housing that rotates within another housing, a first shaft connected to the drive housing, and a second shaft also connected in a rotationally fixed manner. The design includes a hydrostatic displacement machine and a friction clutch that connects the first shaft to the drive housing. The hydraulic clutch operates by producing pressure in a pressure space when a speed difference occurs, which then acts upon the friction clutch. Additionally, a passage leads from the pressure space to a control valve that regulates the pressure in a controlled manner.
Another notable patent is an adjustable viscous shear coupling for all-wheel drive vehicles. This coupling distributes torque between the front and rear axles and consists of a housing with inner and outer blades. The blades are axially spaced and mounted within the housing, filled with a viscous liquid. An adjusting piston within the housing allows for the adjustment of the axial distance between the blades. The system includes a control pressure circuit and a control device that calculates the desired adjusting piston speed based on driving conditions.
