Abstract
Description
Die Erfindung betrifft einen Hilfsrahmen, insbesondere einen Integralträger, für eine Karosserie eines Kraftwagens, gemäß Oberbegriff des Anspruchs 1.The invention relates to a subframe, in particular an integral carrier, for a body of a motor vehicle, according to the preamble of claim 1.
Die
Es ist daher Aufgabe der vorliegenden Erfindung, einen Hilfsrahmen, insbesondere einen Integralträger, für eine Karosserie eines Kraftwagens bereitzustellen, welche ein reduziertes Gewicht aufweist.It is therefore an object of the present invention to provide an auxiliary frame, in particular an integral support, for a body of a motor vehicle, which has a reduced weight.
Diese Aufgabe wird durch einen Hilfsrahmen, insbesondere einen Integralträger, für eine Karosserie eines Kraftwagens mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a subframe, in particular an integral support, for a body of a motor vehicle with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Ein solcher Hilfsrahmen, insbesondere ein Integralträger, für eine Karosserie eines Kraftwagens umfasst zwei, bezogen auf eine Einbaulage, welche der Hilfsrahmen einnimmt, wenn er an der Karosserie befestigt ist, zumindest im Wesentlichen in Fahrzeuglängsrichtung verlaufende Längsträgerelemente. Die Längsträgerelemente sind in Fahrzeugquerrichtung voneinander beabstandet. Der Hilfsrahmen umfasst ferner wenigstens ein zumindest im Wesentlichen in Fahrzeugquerrichtung verlaufendes Querträgerelement, über welches die Längsträgerelemente miteinander verbunden sind. Erfindungsgemäß ist vorgesehen, dass wenigstens eine Lagerstelle zum Lager eines Drehstabs, insbesondere eines Stabilisator-Drehstabs, eines Fahrwerks des Kraftwagens an dem Hilfsrahmen in diesen integriert ist. Durch diese Integration der Lagerstellen in den Hilfsrahmen kann der Drehstab ohne zusätzliche Bauteile sowie Befestigungsmittel an dem Hilfsrahmen über die zumindest eine Lagerstelle insbesondere um eine Drehachse relativ zum Hilfsrahmen drehbar gelagert werden.Such a subframe, in particular an integral support, for a body of a motor vehicle comprises two, based on an installation position, which occupies the subframe, when it is attached to the body, at least substantially extending in the vehicle longitudinal direction longitudinal beam elements. The longitudinal beam elements are spaced apart in the vehicle transverse direction. The subframe furthermore comprises at least one transverse carrier element running at least essentially in the vehicle transverse direction, via which the longitudinal carrier elements are connected to one another. According to the invention it is provided that at least one bearing point for the storage of a torsion bar, in particular a stabilizer torsion bar, a chassis of the motor vehicle on the subframe is integrated in this. As a result of this integration of the bearing points in the subframe, the torsion bar can be rotatably supported relative to the subframe without additional components and fastening means on the subframe via the at least one bearing point, in particular about an axis of rotation.
Ebenso ist es möglich, zumindest ein der in den Hilfsrahmen integrierten Lagerstelle zugeordnetes Lagerteil zum Lagern des Drehstabs an dem Hilfsrahmen ohne zusätzliche Bauteile und/oder ohne zusätzliche Befestigungsmittel an dem Hilfsrahmen zu halten bzw. zu befestigen. Über dieses zumindest eine Lagerteil kann dann der Drehstab besonders steif und mit einer nur sehr geringen Teilezahl an dem Hilfsrahmen insbesondere um eine Drehachse relativ zu dem Hilfsrahmen drehbar gelagert werden.It is also possible, at least one of the integrated in the subframe bearing part associated bearing part for supporting the torsion bar on the subframe without additional components and / or without additional fastening means to hold the subframe or fasten. About this at least one bearing part of the torsion bar can then be mounted particularly rigid and with only a very small number of parts on the subframe, in particular about a rotational axis relative to the subframe rotatably.
Dies hält die Teilezahl und das Gewicht sowie die Kosten des erfindungsgemäßen Hilfsrahmens gering. Ferner können dadurch das Gewicht, die Teilezahl und die Kosten einer Lageranordnung des Drehstabs an dem erfindungsgemäßen Hilfsrahmen, bei welcher der Drehstab über die Lagerstelle an dem Hilfsrahmen insbesondere um eine Drehachse relativ zum Hilfsrahmen drehbar gelagert ist, gering gehalten wird. Dies führt zu einem reduzierten Gewicht des gesamten Kraftwagens. So kann der Kraftwagen, welcher beispielsweise als Personenkraftwagen ausgebildet ist, mit einem reduzierten Energieaufwand betrieben, insbesondere angetrieben, werden. Wird der Kraftwagen beispielsweise mittels einer Verbrennungskraftmaschine angetrieben, so führt dies zu einem reduzierten Kraftstoffverbrauch und damit zu reduzierten CO2-Emission.This keeps the number of parts and the weight and the cost of the subframe according to the invention low. Furthermore, the weight, the number of parts and the cost of a bearing arrangement of the torsion bar on the subframe according to the invention, in which the torsion bar is rotatably supported by the subframe on the subframe, in particular about an axis of rotation relative to the subframe, can be kept small. This leads to a reduced weight of the entire motor vehicle. Thus, the motor vehicle, which is designed for example as a passenger car, operated with a reduced energy consumption, in particular driven. If the motor vehicle is driven for example by means of an internal combustion engine, this leads to a reduced fuel consumption and thus to reduced CO 2 emissions.
Die Integration der Lagerstelle in den Hilfsrahmen birgt weiter den Vorteil, dass dadurch die Lagerung des Drehstabs an dem Hilfsrahmen über die zumindest eine Lagerstelle besonders steif erfolgen kann. Dies kommt insbesondere dem Fahrverhalten des Kraftwagens mit dem erfindungsgemäßen Hilfsrahmen zugute.The integration of the bearing in the subframe has the further advantage that thereby the storage of the torsion bar on the subframe via the at least one bearing point can be made very stiff. This is particularly beneficial to the driving behavior of the motor vehicle with the subframe according to the invention.
Bevorzugt ist eine weitere, in den Hilfsrahmen integrierte Lagerstelle zum Lager des Drehstabs, insbesondere um eine Drehachse relativ zum Hilfsrahmen drehbar, vorgesehen. Vorteilhafterweise ist die erste Lagerstelle auf Seiten eines der Längsträgerelemente angeordnet, während die weitere Lagerstelle von der ersten Lagerstelle in Fahrzeugquerrichtung beabstandet und insbesondere fluchtend zur ersten Lagerstelle angeordnet ist. Somit kann der Drehstab besonders vorteilhaft, steif und mit einem nur geringen Aufwand an dem Hilfsrahmen gelagert werden. Dies hält die Teilezahl, die Kosten und das Gewicht des Hilfsrahmens und damit des gesamten Kraftwagens gering.Preferably, a further, integrated in the subframe bearing to the bearing of the torsion bar, in particular about an axis of rotation relative to the subframe rotatably provided. Advantageously, the first bearing point is arranged on the side of one of the longitudinal support elements, while the further bearing point is spaced from the first bearing point in the vehicle transverse direction and in particular is arranged in alignment with the first bearing point. Thus, the torsion bar can be stored particularly advantageous, rigid and with little effort on the subframe. This keeps the number of parts, the cost and weight of the subframe and thus the entire motor vehicle low.
