  • Fluid-friction clutch with a compensating chamber for viscous fluid
    Patent number: 4938330
    Abstract: In a fluid-friction clutch with a disc stack actuable by an adjusting piston and having resilient spacer parts, the viscous fluid escapes from the shearing gaps between adjacent discs of the stack into a compensating chamber located radially on the outside in relation to the disc stack, in order to ensure a completely torque-free lifting position of the clutch when the adjusting piston is not actuated.

  • Propulsion control using steering angle and vehicle speed to determine tolerance range
    Patent number: 4794539
    Abstract: A propulsion control system for motor vehicles for maintaining stable driving conditions, having a computer unit for determining a desired value or a tolerance range for the rotational speed difference of the front wheels or of the lateral acceleration or of the yaw velocity, and having a comparator unit in which this desired value or tolerance range is compared with the measured actual value, in which case the difference between the actual value of the desired value or tolerance range is used as a control signal for the brakes of the wheels and/or for a power control element of the vehicle engine.
