(EN) DEVICE FOR FRICTION MEASUREMENT
(FR) DISPOSITIF POUR LA MESURE DE FROTTEMENT
Abstract
(DE)
Die Erfindung betrifft eine Einrichtung (1) zur Reibungsmessung an einer Zylinder-Kolben-Anordnung, wobei ein zumindest einen Kolbenring aufweisender, hin- und hergehender Kolben (3) in einer Zylinderlaufbuchse (2) angeordnet ist, mit zumindest einem Dichtelement (17) zwischen Zylinderlaufbuchse (2) und einem Zylinderkopf (9). Um die Messgenauigkeit zu verbessern ist vorgesehen, dass eine innere Mantelfläche (2a) der Zylinderlaufbuchse (2) gegenüber dem Zylinderkopf (9) abgedichtet ist
(EN)
The invention relates to a device (1) for friction measurement on a cylinder-piston arrangement, wherein a to- and fro-moving piston (3) having at least one piston ring is arranged in a cylinder liner (2), having at least one sealing element (17) between cylinder liner (2) and a cylinder head (9). In order to improve measurement accuracy, provision is made for an inner lateral surface (2a) of the cylinder liner (2) to be sealed with respect to the cylinder head (9).
(FR)
L'invention porte sur un dispositif (1) pour la mesure de frottement dans un ensemble cylindre-piston, un piston alternatif (3) qui présente au moins un segment de piston étant disposé dans une chemise de cylindre (2), au moins un élément d'étanchéité (17) étant interposé entre la chemise de cylindre (2) et une culasse (9). Pour améliorer la précision de la mesure, une surface périphérique intérieure (2a) de la chemise de cylindre (2) est rendue étanche par rapport à la culasse (9).
