摘要： A master cylinder for use in the power train of a motor vehicle to actuate the brakes or the friction clutch is designed to avoid the generation of screeching noise and/or the transmission of stray movements to the piston rod in response to shifting of the piston relative to the housing and relative to the sealing element(s) between the piston and the housing. This can be accomplished by causing the piston to turn relative to the housing and the sealing element(s) during axial movement in the housing and/or by installing one or more dampers between the piston and the housing and/or between the piston and the piston rod. The dampers can constitute separately produced parts and/or specially configured and/or finished surfaces provided on the piston and contacting the housing and/or the sealing element(s). The invention also relates to improvements in the configuration and/or the material(s) of the piston.

摘要： A steel component is provided on its surface with an electroplated anti-corrosive coating of a metallic material and has a hardness of at least 650 HV, the anti-corrosive coating being thinner than the surface roughness which the hardened component had before the application of the protective coating. Advantageously, the component is a rolling bearing component with a surface roughness R.sub.z of 0.3 to 9.0 .mu.m and a coating thickness of 0.1 to 3.0 .mu.m. Preferably, the anti-corrosive coating comprises a zinc-cobalt alloy, a zinc-iron alloy or a zinc-nickel alloy coating. It is possible to add iron, tin, copper or chromium to the coating composition.

摘要： In a tightening device for a drive belt in an internal combustion engine, particularly for a toothed belt in the camshaft gear with a tension roller supported on a pivoting lever comprising a tension spring acting upon the pivoting lever in the direction of tension and a blocking device opposing the motion of the pivoting lever, whose blocking element changes its position as a function of the temperature, the blocking element formed as an end stop by the free end (17) of a preferably plate shaped stop body (18) whose other end (19) is held in a fixed housing (1) wherein the end stop in the operating state of the internal combustion engine is disposed at a distance from the adjacent support face of the pivoting lever. The tightening device with the thermally adjustable end stop avoids a tooth jump, particularly in the case of long belts.

摘要： The invention relates to thin-walled rolling bearings, such as needle bearings, which are produced without the removal of material and the outer rings of which form a structural unit and are produced from a cold-rolled strip. According to the invention, the outer rings are produced from a cold-formable, fully hardenable steel, a ratio of from 1:20 to 1:5 being set between their wall thickness and the diameter of the bearing needles, and the fully hardened wall having a core hardness of ≧600 HV and a surface hardness of ≧680 HV. The invention makes it possible for bearings to withstand higher static bearings than bearings made from conventional steels while taking up the same installation space.
