Abstract
Description
Die vorliegende Erfindung betrifft eine kombinierte Fahrzeugbremse, die eine hydraulisch betätigbare Betriebsbremse und eine elektromechanisch betätigbare Feststellbremsvorrichtung aufweist, wobei in einem Bremsgehäuse ein hydraulischer Betriebsdruckraum von einem Bremskolben begrenzt ist, der zur Durchführung von Betriebsbremsungen mit hydraulischem Druckmittel beaufschlagbar ist, so dass der Bremskolben zur Erzielung einer Bremswirkung entlang einer Kolbenlängsachse betätigbar ist, und wobei die Feststellbremsvorrichtung auf den Bremskolben mittels eines Getriebes wirkt, indem das Getriebe die Rotationsbewegung eines elektromechanischen Aktuators in eine Translationsbewegung umsetzt und eine Betätigung des Bremskolbens zur Durchführung von Feststellbremsvorgängen bewirkt und in der betätigten Stellung hält, wobei das Getriebe eine Gewindespindel und eine Gewindemutter aufweist, die über mehrere Wälzkörper miteinander in Kontakt stehen.The The present invention relates to a combined vehicle brake, a hydraulically actuated service brake and a Electromechanically actuated parking brake device having, wherein in a brake housing, a hydraulic Operating pressure chamber is limited by a brake piston, which is to carry out Served by service braking with hydraulic pressure medium is, so that the brake piston to achieve a braking effect along a piston longitudinal axis is actuated, and wherein the parking brake device on the brake piston by means of a Transmission works by the gearbox rotation of a electromechanical actuator translates into a translational movement and an operation of the brake piston for performing effected by parking brake operations and actuated in the Holds position, the gear is a threaded spindle and a threaded nut, which has several rolling elements in contact with each other.
Eine
derartige hydraulische Fahrzeugbremse mit elektrisch betätigbarer
Feststellbremsvorrichtung ist beispielsweise aus der
Aus
dem deutschen Gebrauchsmuster
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die Wälzkörper von einem Wälzkörperkäfig geführt werden, um die Reibkraft zwischen den Wälzkörpern untereinander beim Betätigen des Getriebes zu reduzieren. Dabei bildet der Wälzkörperkäfig eine Führung für die Wälzkörper, sodass ein gegenläufiges aneinander Reiben der Wälzkörper vermieden wird und eine gleichmäßige Reduzierung der Reibkraft zwischen den Wälzkörpern untereinander realisiert wird.These The object is achieved by a device solved with the features of claim 1. It is intended that the rolling elements of a Wälzkörperkäfig be guided to the frictional force between the rolling elements to reduce each other when operating the gearbox. The Wälzkörperkäfig forms a Guide for the rolling elements, so that an opposite rubbing of the rolling elements is avoided and a uniform reduction the frictional force between the rolling elements with each other is realized.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen entnehmbar. Eine vorteilhafte Weiterbildung sieht vor, dass der Wälzkörperkäfig und somit die Wälzkörper zwischen zwei Anschlägen im Gewindegang begrenzt beweglich angeordnet sind, wobei ein Federelement zwischen dem Wälzkörperkäfig und einem Anschlag angeordnet ist und bei einem lastfreien Betätigen des Getriebes ein Rutschen der Wälzkörper ermöglicht und bei einem Betätigen des Getriebes unter Last ein Abrollen der Wälzkörper bewirkt. Beim Rutschen der Wälzkörper im Gewindegang findet keine Relativbewegung zwischen dem Wälzkörperkäfig und der Gewindemutter statt, während sich der Wälzkörperkäfig beim Abrollen der Wälzkörper relativ zur Gewindemutter bewegt. Dieser Abrollweg wird durch das Federelement vorgehalten.Further advantageous embodiments and refinements of the subject invention are the dependent claims. An advantageous development provides that the rolling element cage and thus the rolling elements between two stops in the Thread are limitedly movable, with a spring element between the Wälzkörperkäfig and a Stop is arranged and at a load-free operation the gear allows slipping of the rolling elements and upon actuation of the transmission, under load, unrolling causes the rolling elements. When sliding the rolling elements in Thread finds no relative movement between the Wälzkörperkäfig and the nut takes place while the Wälzkörperkäfig when rolling the rolling elements relative to the threaded nut emotional. This Abrollweg is held by the spring element.
Es ist ein zweites Federelement vorgesehen, das zwischen dem Wälzkörperkäfig und dem anderen Anschlag angeordnet ist. Der Wälzkörperkäfig weist wenigstens eine Anschlagfläche auf, an der sich das erste Federelement und/oder das zweite Federelement am Wälzkörperkäfig abstützen.It a second spring element is provided between the Wälzkörperkäfig and the other stop is arranged. The Wälzkörperkäfig points at least one stop surface on which the first Spring element and / or the second spring element on Wälzkörperkäfig support.
Bei einer weiteren bevorzugten Ausführungsform werden die Wälzkörper vom Wälzkörperkäfig aufgenommen. Die Aufnahme im Wälzkörperkäfig wird durch nach außen oder nach innen erstreckte Zungen realisiert. Diese Zungen sind so gestaltet, dass die die Wälzkörper zumindest teilweise umgreifen.at In another preferred embodiment, the rolling elements taken up by Wälzkörperkäfig. The Intake in the rolling element cage is through realized outwardly or inwardly extended tongues. These tongues are designed so that the rolling elements at least partially encompass.
Der Wälzkörperkäfig besteht aus metallischem Werkstoff oder Kunststoff.Of the Wälzkörperkäfig consists of metallic Material or plastic.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert.
