Abstract: A coupling arrangement is provided with a vibration reduction device and with a clutch device. The vibration reduction device has at least one torsional vibration damper, an input connected to a drive, and an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state. The vibration reduction device has a mass damper system that cooperates with the torsional vibration damper and is connected to the output of the vibration reduction device.

Abstract: A pneumatic vehicle tire having a radial carcass, an at least single-layer belt and a tread that is composed of two layers, a tread cap and a tread base, which are made from different rubber mixtures, in a radial direction, the tread base having a central portion and two lateral portions that extend at least in a radially outward direction from an axial perspective. The two lateral portions are made from a rubber mixture that has a lower dynamic modulus of elasticity E? at 55° C. in accordance with DIN 53513 (measured at an extension of 8%) and a lower hysteresis than the central portion of the tread base for a lower rolling resistance without worsening the handling behavior of the vehicle tire.

Abstract: A method and computer program for electronically regulating the brake force distribution in a pressure medium-operated brake system of a vehicle having at least one front axle brake circuit, associated with a front axle, and at least one rear axle brake circuit, associated with at least one rear axle, in which when the brake system is operated, a rear axle brake pressure, acting in the at least one rear axle brake circuit, is regulated to prevent locking of the rear wheels before locking of the front wheels, and in which the brake pressure at the rear axle is limited only while a pressure value which acts in the rear axle brake circuit is below a prespecified pressure threshold value, but the brake pressure at the rear axle is not limited if the pressure value acting in the rear axle brake circuit is not less than the prespecified pressure threshold value.
