Abstract[German]
Bei einem Pedalgefühlsimulator (14) für eine hydraulische Fahrzeugbremsanlage, mit einem Zylinder (18), in dem ein Kolben (26) axial verschiebbar aufgenommen ist, einem Deckel (24), mit dem ein offenes Stirnende (22) des Zylinders (18) verschlossen ist, einem zu dem Deckel (24) gehörigen ersten Federelement (42), einem zu dem Kolben (26) gehörigen zweiten Federelement (66) und einer zu dem Kolben (26) gehöriger Federkopplung (82), mittels derer das zweite Federelement (66) mit dem Kolben (26) gekoppelt und axial an dem ersten Federelement (42) abgestützt ist, weist die Federkopplung (82) stirnseitig ein zum ersten Federelement (42) gewandtes Abstandselement (84) auf, das in einer Ruheposition von dem zweiten Federelement (66) axial überragend und in einer Belastungsposition axial bündig mit dem zweiten Federelement (66) gestaltet ist.[English]
The invention relates to a pedal feel simulator (14) for a hydraulic vehicle brake system, comprising a cylinder (18) in which a piston (26) is axially displaceably accommodated, a cover (24) with which an open end (22) of the cylinder (18) is closed, a first spring element (42) associated with the cover (24), a second spring element (66) associated with the piston (26), and a spring coupling (82) associated with the piston (26) and by means of which the second spring element (66) is coupled to the piston (26) and supported axially against the first spring element (42). The spring coupling (82) has at its end a spacer element (84) which faces the first spring element (42) and is configured to protrude axially from the second spring element (66) in a rest position and to be axially flush with the second spring element (66) in a load position.[French]
L'invention se rapporte à un simulateur de sensation de pédale (14) destiné à un système de freinage hydraulique de véhicule, comprenant un cylindre (18) dans lequel un piston (26) est logé déplaçable axialement, un couvercle (24) grâce auquel une extrémité ouverte (22) du cylindre (18) est fermée, un premier élément ressort (42) associé au couvercle (24), un second élément ressort (66) associé au piston (26), et un accouplement à ressort (82) associé au piston (26) et au moyen duquel le second élément ressort (66) est accouplé au piston (26) et supporté axialement contre le premier élément ressort (42). L'accouplement à ressort (82) comporte à son extrémité un élément d'espacement (84) qui fait face au premier élément ressort (42) et est conçu pour faire saillie axialement depuis le second élément ressort (66) dans une position de repos et pour être aligné axialement avec le second élément ressort (66) dans une position de charge.
