Abstract: A pressure compensating assembly for a drive mechanism of a vehicle, wherein the drive mechanism includes as drive components an electrical machine a power electronics unit, and a transmission, wherein each drive component is disposed in a respective housing which encloses an air space, wherein at least two air spaces of adjacent housings are interconnected in an air-permeable manner, wherein the pressure compensating assembly includes a pressure compensating member common to all drive components, which member connects the air spaces of all drive components of the drive mechanism to an environment and is disposed above a wading line of the vehicle when the pressure compensating assembly is installed in the vehicle.

Abstract: A seal element for connecting a first component and a second component in a fluid-tight and electrically conductive manner. In this case, the seal element has an electrically conductive support element with a holding region and a main seal region which is angled relative to the holding region. The holding region has a first contact surface on one side for contacting the first component and a second contact surface on the other side for contacting the second component. At least one respective spring tongue which is formed integrally with the support element extends from the first contact surface and the second contact surface in the direction facing away from the respective other contact surface.

Abstract: The invention relates to a vulcanizable rubber composition which comprises a) one or more rubbers cross-linkable by means of amine, b) one or more white fillers and c) one or more polyorganosiloxanes with at least two NH2 groups per molecule. In the rubber compositions the total quantity of organosilane is limited. The rubber compositions after vulcanization result in a good compression set.

Abstract: The invention relates to encapsulated rubber additives in the form of microcapsules having a polymer capsule wall and a core which comprises at least one rubber additive. The invention likewise relates to a method for the production of microcapsules of this type. The microcapsules according to the invention are used during vulcanization of natural and synthetic rubbers.

Abstract: The invention relates to an additive compositions for rubbers and rubber mixtures which contain at least one solid, powdery substance and at least one dispersant, the at least one additive substance being coated with the at least one dispersant. The compositions are present as granulate and are prepared by means of a multi-stage fluidized-bed process. The invention also relates to the use of the additive compositions in the preparation of rubber and products obtained using them.
