Abstract
(DE) Die Erfindung betrifft ein Kraftmesssystem (1 ) umfassend einen Kraftmessbolzen (2), wobei das Kraftmesssystem (1 ) einen ersten Hebelarm (3) und einen mittels einer Lagerstelle (10) schwenkbar an dem ersten Hebelarm (3) gelagerten zweiten Hebelarm (4) aufweist, wobei ein erstes freies Ende (5) des ersten Hebelarms (3) und ein zweites freies Ende (6) des zweiten Hebelarms (4) jeweils mit einem Messkörper (16) derart gekoppelt sind, dass bei einer Kraftbeaufschlagung auf den Messkörper (16) der erste Hebelarm (3) gegenüber dem zweiten Hebelarm (4) verschwenkt wird, wobei an dem ersten Hebelarm (3) oder dem zweiten Hebelarm (4) ein Aufnahmeabschnitt (8) zur kraftschlüssigen Aufnahme des Kraftmessbolzens (2) ausgebildet ist, und der Aufnahmeabschnitt (8) im kraftbeaufschlagten Zustand des Messkörpers (16) an dem ihm gegenüberliegenden Hebelarm (3,4) anliegt.
(EN) The invention relates to a force-measuring system (1) comprising a force-measuring pin (2), wherein: - the force-measuring system (1) comprises a first lever arm (3) and a second lever arm (4) which is pivotably mounted on the first lever arm (3) by means of a bearing point (10); - a first free end (5) of the first lever arm (3) and a second free end (6) of the second lever arm (4) are each coupled to a measurement body (16) such that, when force is applied to the measurement body (16), the first lever arm (3) is pivoted relative to the second lever arm (4); - a holding portion (8) for frictionally holding the force-measuring pin (2) is formed on the first lever arm (3) or on the second lever arm (4), and the holding portion (8) is in contact with the opposite lever arm (3, 4) when force is applied to the measurement body (16).
(FR) L'invention concerne un système de mesure de force (1) comprenant une broche de mesure de force (2) : - le système de mesure de force (1) comprenant un premier bras de levier (3) et un second bras de levier (4) qui est monté pivotant sur le premier bras de levier (3) au moyen d'un point d'appui (10) ; - une première extrémité libre (5) du premier bras de levier (3) et une seconde extrémité libre (6) du second bras de levier (4) étant chacune couplée à un corps de mesure (16) de telle sorte que, lorsqu'une force est appliquée au corps de mesure (16), le premier bras de levier (3) pivote par rapport au second bras de levier (4) ; - une partie de maintien (8) pour maintenir par friction la broche de mesure de force (2) étant formée sur le premier bras de levier (3) ou sur le second bras de levier (4), et la partie de maintien (8) étant en contact avec le bras de levier opposé (3, 4) lorsqu'une force est appliquée au corps de mesure (16).
