摘要:
An apparatus for separating an oil aerosol from air, including a separating element which is configured as an annular coalescer which coalesces the oil or oil mist in a known manner into larger oil drops which settle by gravity in the separating element and downstream therefrom. The separating element is disposed in a housing and fastened to a flanged piece, the flange piece including an adapter element to which additional flanged pieces and/or connecting lines for supplying and carrying away the air are attached.
摘要:
An oil separator for separating oil from oil-laden air has a housing, an inlet for oil-charged air to enter the housing, one or more coalescer elements arranged on a support body inside the housing, and outlets for the separated air and for the separated oil to exit the housing. Each end of the support body and a corresponding end of the coalescer element are fastened to a molded component. At least one molded component is in sealing contact with a sealing surface of the housing.

A method for determining a maximum coefficient of friction μmax between a tire and an underlying surface entails empirically determining a reference curve μref(S) of a coefficient of friction μref as a function of a slip S between the tire and an underlying reference surface, determining a first momentary slip S1 for the tire and a first momentary coefficient of friction μ1 between the tire and the underlying surface at a first instant t1, determining a second momentary slip S2 for the tire and a second momentary coefficient of friction μ2 between the tire and the underlying surface at a second instant t2, computing a slope of the curve μ(S) of the coefficient of friction μ as a function of slip S, and computing the maximum coefficient of friction μmax between the tire and the underlying surface by transforming the reference curve μref(S) on the basis of the slope of the curve μ(S). With the aid of the vehicle devices present in any event in modern motor vehicles it is possible to use the information provided by the vehicle devices to be able to compute the momentary slip S and the momentary coefficient of friction μ. By comparing the momentary curve μ(S) that can be determined from the measuring points (μ1; S1) and (μ2; S2) with the empirically determined reference curve μref(S) it is possible using a suitable mathematical method to very accurately estimate, in particular interpolate, the maximum coefficient of friction μmax for the momentary material pairing of the tire with the underlying surface.

For controlling a traction slip control system with brake and motor management, motor regulating signals (m) are derived from electrical signals indicative of the brake pressure or which influence the brake pressure. Preferably, a brake pressure pattern (p[t]) is formed taking into account the pressure build-up and pressure decrease characterics of the wheel brakes or of the entire system as a basis for computing the motor regulating signals (m).
