Abstract
Description
Die vorliegende Erfindung betrifft eine kombinierte Fahrzeugbremse 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 present invention relates to a combined vehicle brake vehicle brake, a hydraulically actuated service brake and an electromechanical actuatable parking brake device, wherein in a brake housing, a hydraulic operating pressure chamber is limited by a brake piston, the implementation 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
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine kombinierte Fahrzeugbremse der eingangs genannten Gattung dahingehend zu verbessern, dass ein Verklemmen des Getriebes verhindert wird.Of the The present invention is therefore based on the object, a combined Vehicle brake of the type mentioned to improve to that jamming of the transmission is prevented.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass mechanische Mittel vorgesehen sind, die ein Verklemmen zwischen einem Kragen der Gewindespindel und der Gewindemutter verhindern.These The object is achieved by a device solved with the features of claim 1. It is intended that mechanical means are provided, the jamming between prevent a collar of the threaded spindle and the threaded nut.
In einer ersten Ausführungsform sind die mechanischen Mittel durch eine Erhebung an der dem Antrieb abgewandten Ende der Gewindespindel gebildet, die mit einer Anschlagfläche in der Gewindemutter zusammenwirkt.In In a first embodiment, the mechanical means by a survey on the end facing away from the drive of the threaded spindle formed with a stop surface in the threaded nut interacts.
In einer zweiten Ausführung sind die mechanischen Mittel durch eine Erhebung in der Gewindemutter gebildet, die mit einer Anschlagfläche an der dem Antrieb abgewandten Ende der Gewindespindel zusammenwirkt.In In a second embodiment, the mechanical means are through a survey formed in the nut, with a stop surface cooperates at the end facing away from the drive of the threaded spindle.
Bei beiden Ausführungsformen ist erfindungsgemäß vorgesehen, dass der Abstand zwischen der Erhebung und der Anschlagfläche geringer ist, als der Abstand zwischen einem Kragen der Gewindespindel und einer dem Kragen zugewandten Aufstandsfläche der Gewindemutter.at Both embodiments are provided according to the invention, that the distance between the survey and the stop surface is less than the distance between a collar of the threaded spindle and a collar facing the footprint of the threaded nut.
Bei einer vorteilhaften Weiterbildung ist der Kragen der Gewindespindel von einer Stufenbohrung im Bremsgehäuse aufgenommen wird und über ein Axiallager am Bremsgehäuse abgestützt wird.at An advantageous development is the collar of the threaded spindle is absorbed by a stepped bore in the brake housing and supported by a thrust bearing on the brake housing becomes.
Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. In der Zeichnung zeigen:The Invention will be described below with reference to two embodiments explained in more detail in connection with the accompanying drawings. In the drawing show:
