    摘要: A wheel bearing arrangement with first rolling elements, which are capable of rolling on a first inner ring, wherein the rolling elements are guided by a first roller bearing cage, and an axial spacer element is provided for spacing apart the first inner ring from a bearing element, wherein the bearing element can in particular be a second inner ring. The intention is to facilitate the complex installation of the individual parts in wheel bearings for utility vehicles. The first rolling element cage forms, together with the axial spacer element, an axial form-fitting connection. The spacer element can be fixed to at least one of the inner rings via the form-fitting connection to the cage prior to tightening the wheel hub, together with the wheel bearing preinstalled thereon.

    摘要: A wheel bearing unit having a wheel hub which is mounted rotatably on a bearing journal by means of two tapered roller bearings which are spaced apart axially. The wheel bearing includes one outer ring, one inner ring and one roller crown ring which is formed from tapered rollers and a bearing cage. The tapered roller bearings are received by their outer rings on one axial stop of the wheel hub such that they are directed counter to one another, and the inner rings of the tapered roller bearings are spaced apart axially from one another by means of a sleeve wherein the wheel hub, tapered roller bearing and sleeve form a self-retaining assembly in the non-installed state of the wheel bearing unit. Both tapered roller bearings are secured axially by one securing means which is received directly on the wheel hub and covers the roller crown ring radially.

    摘要: The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
