Aufgabe der Erfindung ist es, eine Feststellbremse für eine Fahrzeugtür anzugeben, welche reproduzierbare und genaue Bremsvorgänge innerhalb des Bewegungsbereichs der Fahrzeugtür ermöglicht.task the invention is to provide a parking brake for a vehicle door, which reproducible and accurate braking within the range of motion the vehicle door allows.
Die Erfindung löst diese Aufgabe durch Bereitstellung einer Feststellbremse für eine Fahrzeugtür mit den Merkmalen des Patentanspruchs 1.The Invention solves This object by providing a parking brake for a vehicle door with the Features of claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß umfasst eine Feststellbremse für eine Fahrzeugtür eine Bremseinheit, welche gesteuert von einem elektrischen Steuerelement über ein Kraftelement eine vorgebbare Bremskraft erzeugt, welche den Reibschluss zwischen einem ersten Reibelement und einem zweiten Reibelement herstellt, wobei die Bremseinheit als Lamellenbremse mit mindestens einer Lamelle als erstes Reibelement und mindestens einer Lamelle als zweites Reibelement oder als Kegelbremse mit einem Außenkegel als erstes Reibelement und einem Innenkegel als zweites Reibelement ausgeführt ist. Dadurch ist es in vorteilhafter Weise möglich, die Bewegung der Fahrzeugtür innerhalb des zugehörigen Bewegungsbereichs über eine Beeinflussung von entsprechenden Halteelementen abzubremsen und/oder in beliebigen Positionen zu blockieren. Durch das elektrische Steuerelement, welches beispielsweise Informationen von einer Sensorik zur Hinderniserkennung auswertet, ist es in vorteilhafter Weise möglich, die Fahrzeugtür reproduzierbar und genau und damit zuverlässig abzubremsen, wenn beispielsweise ein Hindernis im Bewegungsbereich der Fahrzeugtür erkannt wird, oder die Fahrzeugtür unabhängig von der Fahrzeuglage in beliebigen Öffnungsstellungen innerhalb des Bewegungsbereichs zu blockieren. Ein erstes Halteelement ist beispielsweise an der Fahrzeugkarosserie befestigt und ein zweites Halteelement, welches über einen Scharnierbolzen mit dem ersten Halteelement relativbeweglich verbunden ist, ist an der Fahrzeugtür befestigt, wobei der Scharnierbolzen drehfest mit dem ersten Halteelement oder dem zweiten Halteelement verbunden ist. Die Ausführung der Bremseinheit als Lamellenbremse kann hohe Momente abbremsen und weist den Vorteil einer kompakten Bauform auf.According to the invention a parking brake for a vehicle door a brake unit which is controlled by an electric control via a Force element generates a predetermined braking force, which the frictional engagement between a first friction element and a second friction element manufactures, wherein the brake unit as a multi-disc brake with at least a lamella as the first friction element and at least one lamella as a second friction element or as a cone brake with an outer cone as a first friction element and an inner cone as a second friction element accomplished is. This makes it possible in an advantageous manner, the movement of the vehicle door within of the associated Range of motion over to slow down an influence of corresponding retaining elements and / or block in any position. By the electric Control, which, for example, information from a sensor evaluates for obstacle detection, it is in an advantageous manner possible, the vehicle door reproducible and accurate and thus reliably decelerate, for example an obstacle is detected in the range of movement of the vehicle door, or the vehicle door independent of the vehicle position in any open positions within the movement area. A first holding element For example, it is attached to the vehicle body and a second one Holding element, which over a hinge pin with the first holding element relatively movable is attached to the vehicle door, wherein the hinge pin rotatably with the first holding element or the second holding element connected is. Execution The brake unit as a multi-disc brake can slow down high moments and has the advantage of a compact design.
In Ausgestaltung der erfindungsgemäßen Feststellbremse steht das erste Reibelement beispielsweise mit dem ersten Halteelement in Wirkverbindung und das zweite Reibelement steht mit dem zweiten Halteelement in Wirkverbindung.In Embodiment of the parking brake according to the invention is the first friction element, for example, with the first holding element in operative connection and the second friction element is connected to the second Retaining element in operative connection.
In weiterer Ausgestaltung der erfindungsgemäßen Feststellbremse umfasst das elektrische Steuerelement mindestens ein Piezoelement, welches in beliebigen Türöffungsstellungen über das Kraftelement die erforderliche Bremskraft und/oder Haltekraft als axiale Anpresskraft erzeugt, welche die Reibelemente aufeinander presst.In further embodiment of the parking brake according to the invention comprises the electrical control at least one piezoelectric element, which in any door opening positions over the Force element the required braking force and / or holding force as generates axial contact force, which the friction elements to each other pressed.
Das elektrische Steuerelement ist beispielsweise zwischen den Reibelementen und dem Kraftelement angeordnet. Alternativ kann das Kraftelement zwischen den Reibelementen und dem Steuerelement angeordnet sein.The electrical control is, for example, between the friction elements and the force element. Alternatively, the force element be arranged between the friction elements and the control.
In weiterer Ausgestaltung der erfindungsgemäßen Feststellbremse ist die maximale erzeugbare axiale Anpresskraft über ein Radienverhältnis der Reibfläche der Lamellen oder der Kegel einstellbar, d.h. über das Verhältnis eines Außenradius zu einem Innenradius. Alternativ oder zusätzlich kann die maximal erzeugbare Anpresskraft über die Anzahl der Reibflächen, d.h. über die Anzahl der als Reibelemente verwendeten Lamellen eingestellt werden.In Another embodiment of the parking brake according to the invention is the maximum producible axial contact force over a radius ratio of friction surface the lamella or cone adjustable, i. about the relationship of a outer radius to an inner radius. Alternatively or additionally, the maximum producible contact pressure on the Number of friction surfaces, i.e. above set the number of slats used as friction elements become.
In weiterer Ausgestaltung der erfindungsgemäßen Feststellbremse wird die maximale Anpresskraft in Abhängigkeit von Masse und Hebelarm der Fahrzeugtür und der gewünschten Haltekraft vorgegeben, d.h. in Abhängigkeit von den Abmessungen und dem Gewicht der Fahrzeugtür.In Another embodiment of the parking brake according to the invention is the maximum contact force in dependence of mass and lever arm of the vehicle door and the desired Holding force given, i. depending on the dimensions and the weight of the vehicle door.

Feststellbremse wird günstiger

Kegelbremse weist eine geringere Pressung p und kleinere Anpresskraft
F als die Lamellenbremse auf. Da die Reibfläche der Kegelbremse über den
Konus ausgeführt
wird, weist die Lamellenbremse bei einem Vergleich der Bauhöhe h des
Kegels mit der Bauhöhe der
Lamellen in der Regel eine kompaktere Bauform als die Kegelbremse

Wie aus der Tabelle 1 ersichtlich ist, wird der Grenzwinkel αn, bei welchem die Kegelbremse bei gleicher Bremswirkung günstiger als die Lamellenbremse ist, mit der Erhöhung der Anzahl von Reibflächen der Lamellenbremse immer kleiner. Dies ergibt sich aus der notwendigen Vergrößerung der Kontaktreibfläche. Je mehr Lamellen d.h. Reibflächen zu ersetzen sind, desto ungünstiger ist die konstruktive alternative Ausführungsform mit der Kegelbremse.As can be seen from Table 1, the critical angle α n , at which the cone brake at the same braking effect is cheaper than the multi-disc brake, with the increase in the number of friction surfaces of the multi-disc brake is always smaller. This results from the necessary enlargement of the contact friction surface. The more fins, ie friction surfaces, are to be replaced, the less favorable is the constructive alternative embodiment with the cone brake.
