Description

The present invention relates to a door hinge for a motor vehicle door according to the preamble of the first claim, as well as a motor vehicle door with such a door hinge according to claim 9 and a motor vehicle with such a motor vehicle door according to claim 10.

From the DE 10 2010 035 985 B3 a door hinge for a motor vehicle door is known, which comprises a counter-holding means, a connecting means, a contact surface enlarging means and a hinge means which are fastened to the vehicle door by means of the connecting means and connectable to each other.

Furthermore, the shows CH 63 066 A in that two holding means similar to the counter-holding means and the contact surface enlarging means are connected via connecting means and are displaceable relative to one another.

Furthermore, door hinges are known from the prior art, which comprise a door-side hinge means and a body-side hinge means. The door-side hinge means is firmly connected to the motor vehicle door. The body-side hinge means is firmly connected to the body. The two hinge means are connected by a bolt and rotatably mounted to each other. In this way, the vehicle door can be opened and closed.

The door-side hinge means is fixed in the prior art using a counter-holder and a contact surface enlarging means on the motor vehicle door. A section of the motor vehicle door is arranged between the hinge means and the contact surface enlarging means. The contact surface enlarging means is in turn disposed between the anvil and the portion of the vehicle door. It serves to increase the contact surface with the motor vehicle door in order to be able to transmit forces well without any deformation of the section of the motor vehicle door. A recess of the hinge means, a recess of the contact surface enlarging means, a recess of the counter-holder and a recess in the motor vehicle door are aligned with each other so that a screw can be passed through the four recesses. The screw thus connects the hinge means, the motor vehicle door, the contact surface enlarging means and the anvil with each other. A nut fixes the screw.

In contrast, the invention has for its object to provide a door hinge that simplifies the compensation of manufacturing tolerances. In addition, a motor vehicle door and a motor vehicle to be created with such a door hinge.

This object is achieved by a door hinge according to claim 1, a motor vehicle door according to claim 9 and a motor vehicle according to claim 10. Embodiments of the invention are indicated in the dependent claims.

According to claim 1, the door hinge comprises a counter-holding means, a connecting means, a contact surface enlarging means and a hinge means. In this case, a hinge means is understood to mean, in particular, a component of a hinge which can be connected rotatably to one another with a further hinge means, for example by means of a bolt. The hinge means may for example be a door-side hinge means. The further hinge means may be a body-side hinge means.

The hinge means, the contact surface enlarging means and the counter-holding means are adapted to be fixed to the motor vehicle door. A portion of the vehicle door is disposed between the hinge means and the contact surface enlarging means. The contact surface enlarging means is disposed between the portion of the vehicle door and the counter-holding means. The hinge means, the contact surface enlarging means and the counter-holding means are interconnected by the connecting means. The connecting means may for example comprise a screw.

It is now provided that the counter-holding means is displaceable relative to the contact surface enlarging means when it is connected to the contact surface enlarging means via the connecting means.

For example, a loose connection and a fixed connection of the contact surface enlarging means with the counter-holding means can be produced via the connecting means. While the loose connection exists, the counter-holding means can be displaced relative to the contact-surface enlarging means. With the fixed connection a shift is not possible. The connecting means may for example be a screw that can be tightened to different degrees.

When mounting the motor vehicle door on the motor vehicle, the hinge means can be rotatably connected via a bolt with a further hinge means, which is arranged on the motor vehicle. Usually, thereafter, a positioning of the motor vehicle door relative to the motor vehicle, so that production-related tolerances be compensated. This positioning is now particularly easy to carry out, since the counter-holding means is displaceable relative to the contact surface enlarging means. The vehicle door can thus be moved relative to the vehicle, without the connection of the individual components of the door hinge must be solved. Once the vehicle door is positioned as desired, a firm connection of the components can be made with each other, so that a shift relative to each other is no longer possible.

The invention thus simplifies the compensation of production-related tolerances. The motor vehicle door can be connected to the motor vehicle. While this connection is made, the vehicle door can be positioned to compensate for tolerances.

The contact surface enlarging means may for example be permanently connected to the motor vehicle door. A permanent connection means in particular that the connection can not be released without damaging the motor vehicle door and / or the contact surface enlarging means. For example, a permanent connection may be a riveted joint or a welded joint.

According to one embodiment of the invention, the counter-holding means, the hinge means and the contact surface enlarging means may each have a recess. The connecting means may be adapted to connect the counter-holding means, the hinge means and the contact surface enlarging means by projecting through the recesses.

According to one embodiment of the invention, the recess of the contact surface enlarging means may be larger than the recesses of the hinge means and the counter-holding means. It is thus achieved that both the hinge means and the counter-holding means are displaceable relative to the contact surface enlarging means. This facilitates the positioning of the motor vehicle door relative to the motor vehicle in particular when the contact surface enlarging means is permanently connected to the motor vehicle door, since both the counter-holding means and the hinge means are displaceable relative to the contact surface enlarging means - and thus also relative to the motor vehicle door.

According to one embodiment of the invention, the counter-holding means in the mounted on the motor vehicle door state in the vertical direction relative to the contact surface enlarging means to be displaced. It is also possible that the hinge means is displaceable in the vertical direction relative to the contact surface enlarging means. The counter-holding means and / or the hinge means may additionally be displaceable in the horizontal direction relative to the contact surface enlarging means.

According to one embodiment of the invention, the connecting means may comprise a screw, so that the assembly is particularly simple.

According to one embodiment of the invention, the counter-holding means can be inserted into the contact surface enlarging means. This also facilitates the assembly effort. For example, the contact surface enlarging means may be formed like a profile. At least a portion of the contact surface enlarging means may be formed as a hollow profile section. The cross section of the hollow profile section may correspond to an outer shape of the counter-holding means. Thus, the counter-holding means can be easily inserted into the contact surface enlarging means. In at least one direction, which is perpendicular to the insertion direction, the counter-holding means is then positively connected to the contact surface enlarging means. In particular, the contact surface enlarging means may be formed as an aluminum extruded profile. It is also possible for the contact surface enlarging means to have hollow chambers which increase the stability of the contact surface enlarging means.

According to one embodiment of the invention, the counter-holding means can be connectable via a latching connection with the contact surface enlarging means. There is thus provided a further possibility for connecting the contact area enlarging means with the counterpart means. The snap-in connection facilitates assembly in particular in that the counter-holding means is already connected to the contact surface enlarging means before the connecting means is used. Thus, the connection of the components of the door hinge is simplified with each other. Once the counter-holding means is connected to the contact surface enlarging means via the connecting means, the latching connection can be released.

According to one embodiment of the invention, the door hinge may comprise a further door hinge means, which is fastened to a body component of the motor vehicle. This door hinge means may also be referred to as a body-side door hinge means. The two door hinge means can be rotatably mounted to each other. For example, the two door hinge means may be connected to each other via a bolt.

The door hinge 100 comprises a door-side hinge means 101 with a recess 102 and a connection section 103 , The connecting section 103 is used to connect to a in 1 not shown body-side hinge means 200 , It also includes the door hinge 100 a counter-agent 104 with a recess 105 and a contact area increasing means 106 with an in 7 illustrated recess 700 , Furthermore, the hinge includes 100 a connecting means 108 , The hinge means 101 , the antidote 104 and the contact area increasing agent 106 can be by means of the connecting means 108 connect by the connecting means 108 through the recesses 102 . 700 and 105 is guided and fixed. The contact area increasing agent 106 also has a hollow profile section 107 whose cross-sectional area is larger than the outer shape of the counter-holding means 104 ,

The composite door hinge is in the 2 to 4 shown. The body-side hinge means 200 is rotatable about a bolt with the door-side hinge means 101 connected. For this purpose, the bolt through the connecting portion 103 of the door-side hinge means 101 guided.

Between the door-side hinge means 101 and the contact area increasing means 106 a section of the motor vehicle door is arranged. In 2 a part of a front side of the motor vehicle door is shown. In 3 the same part is shown from the back. It will be apparent that a portion of the vehicle door between the door-side hinge means 101 and the contact area increasing means 106 is arranged.

The motor vehicle door may, for example, be an aluminum door which has a relatively low bending stiffness in comparison with a steel door. The contact area increasing agent 106 provides a sufficiently large contact surface with the vehicle door. Without using the contact surface enlarging agent 106 would be the contact surface between the motor vehicle door and the counter-holding means 104 smaller, so that the stability might not be sufficient.

By using the contact surface enlarging agent 106 is thus made possible for an aluminum door, the counter-holding means 104 , the lanyard 108 and the door-side hinge means 101 to choose as it would be used in a steel door. The lower bending stiffness of the aluminum door is compensated by the enlargement of the contact surface, so that occurring forces are transmitted reliably to the motor vehicle door without or with a relatively small deformation of the motor vehicle door.

In 5 is particularly well the hollow profile section 107 of the contact surface enlarging agent 106 to recognize. As the cross-sectional area of the hollow profile section 107 larger than the outer shape of the counter-holding means 104 , the counter-agent can be 104 simply in the contact surface enlarging agent 106 Push. The insertion direction extends perpendicular to the direction in which the connecting means 108 the contact area increasing agent 106 with the counter-agent 104 combines. After inserting the counter-agent 104 it can be in the vertical direction relative to the contact surface enlargement means 106 and move to the vehicle door. This also allows the door-side hinge means 101 relative to the contact surface enlarging agent 106 and move to the vehicle door. The motor vehicle door can thus be particularly easily positioned relative to the motor vehicle when the two hinge means 101 and 200 already connected with each other and if the antithesis means 104 already with the contact surface enlarging agent 106 and the door-side hinge means 101 connected is. As soon as the desired position has been reached, the connection of the components can be fixed so that it is no longer possible to displace the components relative to one another. This can be achieved, for example, by using as connecting means 108 a screw is used and at the recess 105 of the counter-agent 106 an internal thread is provided.

The displacement is achieved in particular by the fact that the recess 700 of the contact surface enlarging agent 106 greater than the outer diameter of the bonding agent 108 and as the recesses 105 and 102 of the counter-agent 105 and the hinge means 101 ,
