Abstract
Description
Die Erfindung betrifft eine Servolenkung, insbesondere eine Hilfskraftlenkung für ein Fahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a power steering, in particular a power steering system for a vehicle, according to the preamble of claim 1.
Die
Sind einer oder beide der Faltenbälge beschädigt, so ist die gesamte Servolenkung nicht mehr dicht und es kann Flüssigkeit, wie Betriebstoffe, insbesondere aber Feuchtigkeit in Form von Spritzwasser in das Lenkgetriebegehäuse eintreten. Das Wasser sammelt sich innerhalb des Lenkgetriebegehäuses. Besonders problematisch ist die Situation, wenn das Fahrzeug mit dem eingedrungenen Wasser in dem Lenkgetriebegehäuse in einer Garage abgestellt wird und nach Fahrtantritt das Wasser aufgrund Minustemperaturen gefriert. Ein Fahrer des Fahrzeugs bemerkt dann zunächst keine Beeinträchtigung des Lenkverhaltens, wenn jedoch das Wasser gefriert und insbesondere einen Eiskeil zwischen dem Zugmittel und dem Rad oder den Rädern des Zugmittegetriebes bildet, kann dies unter Umständen zu einer Beeinträchtigung der Lenkfähigkeit des Fahrzeugs führen.are one or both of the bellows damaged, so the entire power steering is no longer tight and it can be liquid, as operating materials, but especially moisture in the form of water spray enter the steering gear housing. The water collects within the steering gear housing. Especially problematic is the situation when the vehicle with the penetrated water is parked in the steering gear housing in a garage and after driving the water freezes due to cold temperatures. A driver of the vehicle then noticed initially no impairment the steering behavior, however, when the water freezes and in particular an ice wedge between the traction means and the wheel or wheels of the Zugmittegetriebes, this may under certain circumstances to a deterioration of the steering ability of the Lead vehicle.

Vermeidung solcher Situationen schlägt die

Die
Der Erfindung liegt die Aufgabe zugrunde, eine Servolenkung anzugeben, deren Betrieb sicher ist.Of the Invention has for its object to provide a power steering their operation is safe.
Die Aufgabe wird mit einer Servolenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a power steering with the features of the claim 1 solved.
Dadurch dass zumindest eine Scheibe oder ein Rad und das Zugmittel des Zugmittelgetriebes mit Hilfe eines diese Teile zumindest teilweise umschließenden Bauelements vor Zutritt von in das Lenkgetriebegehäuse eingedrungener Flüssigkeit, insbesondere Wasser geschützt ist, kann keine Funktionsbeeinträchtigung der Servolenkung durch Eisbildung in dem Lenkgetriebegehäuse oder in dem Zugmittelgetriebe erfolgen.Thereby that at least one disc or a wheel and the traction means of the traction mechanism with the help of one of these parts at least partially enclosing Component before access of the steering gear housing penetrated liquid, especially water protected is, no functional impairment of the power steering by ice formation in the steering gear housing or in the Traction mechanism made.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel der Servolenkung ist das gegen Wasser das Zugmittelgetriebe schützende Bauelement aus einem Kunststoff, etwa als Spritzgussbauteil gebildet und bevorzugt einteilig gebildet. Es kann auch zweckmäßig sein, das Bauelement mehrteilig zu bilden. Bevorzugt ist das Bauelement als Wanne oder wannenartig gebildet in dem das Zugmittel und ein oder mehrere Scheiben oder Räder des Zugmittelgetriebes sich bewegen. Die Wanne wird bevorzugt bei der Montage der Servolenkung im Bereich des Gehäuses des Zugmittelgetriebes eingelegt und vormontiert, wobei es zweckmäßig ist, an dem Bauelement, insbesondere an der Wannenaußenseite Befestigungselemente, wie etwa Nasen oder Rippen vorzusehen, mit denen sich das Bauelement an umliegenden Teilen des Lenkgetriebegehäuses abstützt oder formschlüssig lösbar festgelegt werden kann.In a particularly preferred exemplary embodiment of the power steering system, the component which protects the traction mechanism against water is made of a plastic, for example formed as an injection-molded component and preferably formed in one piece. It may also be expedient to form the component in several parts. Preferably, the device is formed as a trough or tub-like in which the traction means and one or more discs or wheels of the traction mechanism to move. The tub is preferably inserted and preassembled during installation of the power steering in the region of the housing of the traction mechanism, wherein it is expedient, on the component, in particular on the outside of the tub fasteners, such as lugs or ribs provide, with which the component is supported on surrounding parts of the steering gear housing or can be fixed releasably releasably.
Rippen oder Nasen an dem Bauelement oder der Wanne ermöglichen ein Umfließen der Wanne oder des Bauelements von dem eingedrungen Wasser. Sind an geeigneter Stelle in dem Lenkgetriebegehäuse Bohrungen oder Kanäle angeordnet, so kann Wasser an eine elektrische Sensoreinrichtung, die bevorzugt Teil einer Steuer- und/oder Regelungseinrichtung der Servolenkung ist, gelangen. Dadurch ist die Ausgabe eines Signals an einen Fahrer des Fahrzeugs ermöglicht.ribs or lugs on the device or the tub allow a flow around the tub or the component of the penetrated water. Are at a suitable location in the steering gear housing holes or channels arranged so water can be connected to an electrical Sensor device, which preferably part of a control and / or regulating device the power steering is, get. This is the output of a signal to a driver of the vehicle.
