摘要： The invention relates to a flat-track unit for motor vehicle test beds comprising a roadway-simulating belt guided over two rollers. So that skew angles between belt running direction and wheel plane can be realized as close to reality as possible on the test bed, the frame supporting the guide rollers of the belt is pivotably mounted about a vertical axis and is provided with a pivot drive variable in a high-frequency manner. The drive and braking unit for the rollers is arranged so as to be spaced from the flat-track unit and mounted in a fixed position in the vertical direction, while it is displaceable on a circular arc-shaped horizontal guide running concentrically to the vertical axis. A corresponding displacement drive is provided for the drive and brake unit. The latter causes the drive and braking unit to follow, at a comparatively slow speed, the belt running directions of the flat-track unit and on which belt torsional oscillations are superimposed. A universal-joint shaft is arranged between flat-track unit and the drive and braking unit and is held in an approximately straightened position.

摘要： The invention relates to a flat-track unit for motor-vehicle test beds in which a roadway-simulating belt is guided over two rollers lying in parallel. The upper test side of the belt lies roughly at ground level and accommodates a vehicle wheel and can be excited by a supporting shoe below the belt via an excitation cylinder to develop vertical oscillations which are to simulate roadway vibrations. The two belt-guiding rollers are in turn mounted in a frame which in turn is guided so as to be vertically movable and can be excited by a further excitation cylinder to develop vertical oscillations. In the process, the supporting shoe oscillations are limited to short-stroke and high-frequency oscillation portions of simulated driving conditions whereas the frame is excited merely by the long-stroke and low-frequency oscillation portions. This offers the advantage that long-stroke vertical oscillations can also be reproduced in a manner close to reality, but nonetheless, the vertical oscillations of the test side, relative to the belt guide rollers, are only relatively small. By the use of hollow pistons, the required excitation energy is kept within acceptable limits and over all weight is reduced.

摘要： A compact device is provided for sampling particles from the exhaust gases of an internal combustion engine for an automotive vehicle. The device includes a dilution tunnel, to which is supplied all the exhaust gases of the internal combustion engine. From the dilution tunnel, by way of an exhaust gas distributor, a sample stream of exhaust gas is distributed to filter cylinders arranged in exhaust gas conduits in dependence on the operation of the internal combustion engine. Filter units, traversed by the sample stream of exhaust gas, are removably disposed in the filter cylinders which are vertically arranged and exhibit a filter mounting element accommodating the filter units. This filter mounting element is adapted to be swung out laterally from the filter cylinders after opening of a locking device. A plurality of filter cylinders are provided, each being associated with a specific operating phase of the internal combustion engine, and being utilized for determination of the quantity of emitted particles. A filter cylinder designed as a static cylinder is also provided. Upstream and downstream of each filter cylinder, valves are arranged which are adapted to control the flow of exhaust gas through the individual cylinders.

摘要： An exhaust adapter for exhaust gas measurements which can be attached to the tail pipe of an exhaust unit and to which can be connected a hose leading to the analyzing measuring system. Two pipes, one telescoped into the other, are provided for attachment to a tail pipe. An elastic sealing ring is arranged between the end edge of the inner pipe and a drawn-in collar of the outer pipe. The outer pipe may be restrained with respect to the inner pipe for a gastight seal on the tail pipe by the measure of a compression of the sealing ring.
