Description

The invention relates to a motor vehicle hinge with a first hinge part and a second hinge part, which are hinged together.

Motor vehicle hinges of the type mentioned are known in various embodiments of the prior art. They are used in motor vehicles for the articulated arrangement of a door, hood, flap or the like with respect to a vehicle body, the different requirements according to a variety of specialized motor vehicle hinges exist in which arranged a hinge part on the vehicle body and the other hinge part with the articulated to connect to the body Component, d. H. the door, flap, hood or the like is connected.

An important area of such motor vehicle hinges are motor vehicle door hinges, which are subject to a particularly high level of stress and, moreover, are subject to particularly high demands on ease of use and reliability. In addition to the simple articulated arrangement of a vehicle door with respect to the vehicle body and, for example, a reliable locking of the vehicle door via the motor vehicle door hinge, particularly high demands are placed on the crash properties of the door hinges. Thus, the motor vehicle door hinges must be designed such that even with an injured vehicle an opening possibility remains, so that rapid access to the interior and the persons possibly injured therein is given.

Known motor vehicle door hinges have the disadvantage that the pivotability of the door hinge is no longer given a too high degree of deformation. Further, an opening of the vehicle door on the predetermined by the motor vehicle door hinge pivot axis is not possible if the position of the vehicle crashed a pivoting of the vehicle door is blocked by the predetermined by the motor vehicle door hinge pivot axis. This danger concerns, for example, sports cars with special type of door such as gullwing doors, which, for example, in the case of a crashed vehicle located on a roof offer no opening possibility.

The invention has for its object to provide a motor vehicle hinge, which offers a reliable opening possibility even with accident vehicles.

The invention achieves the object by a motor vehicle hinge with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

aufweist, wobei die Verriegelungseinheit einen sich durch den Grundkörper und das Kopplungselement erstreckenden Sperrstift aufweist, der in der Normallage den Grundkörper und das Kopplungselement in Sperrstiftlängsachsenrichtung zwischen einem an einer Außenfläche von Kopplungselement oder Grundkörper anliegenden Anschlagelement des Sperrstifts und einer auf das dem Anschlagelement gegenüberliegende Ende aufschraubbaren Stellmutter gegeneinander verspannt.Characteristic of the motor vehicle hinge according to the invention is that the first or second hinge part

• a base body that can be arranged on the vehicle,
• one with the other hinge part hingedly connectable coupling element,
• a locking unit, which is adjustable between a coupling element and the base body in a normal position defining locking position and a coupling element separable from the main body release position, and
• an actuating unit for adjusting the locking unit from the blocking position to the release position

wherein the locking unit has a locking pin extending through the base body and the coupling element, which in the normal position the base body and the coupling element in Sperrstiftlängsachserichtung between a voltage applied to an outer surface of the coupling element or body abutment element of the locking pin and a screwed onto the stop element opposite end Adjusting nut braced against each other.

Essential for the motor vehicle hinge according to the invention, which has a first and a second articulated hinged hinge part, is that one of the two hinge parts has a special configuration, namely a base body and a coupling element connected to the main body has, with a separation between the main body and the Coupling element consists. As a result, if necessary, a separation of the hinge and thus a distance of the hinge with the Vehicle body connected component possible.

Basically, the motor vehicle hinge according to the invention via the first and second hinge part allows a simple and reliable articulated arrangement of a door, flap, hood or the like on a vehicle body. A first hinge part is on the body side, d. H. connected to the vehicle body and the second hinge part is connected to the articulated to be connected to the vehicle body component. About the articulated connection of the first and second hinge part then there is the possibility to adjust the connected component relative to the vehicle body, for example. To pivot.

According to the invention, one of the two hinge parts has an at least two-part construction. A hinge part thus consists of at least one base body, which on the vehicle side, d. H. A door, a flap or a hood can be arranged on the vehicle body or on the vehicle part to be connected to the vehicle body, and a coupling element connected to the base body can be produced, wherein an articulated connection with the second hinge part can be produced via the coupling element.

In a normal operation of the motor vehicle hinge, the locking unit of the motor vehicle hinge serves to fix the coupling element to the base body, so that the motor vehicle hinge according to the invention does not differ in operation from conventional motor vehicle hinges with one-piece hinge parts. The hinge part composed of at least one base body and one coupling element thus behaves like the connected hinge part, which is known from the prior art and is generally designed in one piece.

The position assurance of the main body on the coupling element is effected by a locking pin which extends through the base body and the coupling element. A separation of these components is blocked by a stop element as well as an adjusting nut which can be screwed onto the end opposite the stop element, since the stop element and the adjusting nut bear against the main body or the coupling element on the outside. Accordingly, the coupling element and the main body between the stopper element and the set screw "pinched".

However, the locking unit according to the invention offers the possibility of an adjustment of the coupling element and the body in the normal position each other defining locking position in a release position in which the coupling element is separable from the body. The separability thus makes it possible to cancel the connection between the vehicle body and the connected component produced via the motor vehicle hinge according to the invention, so that, for example, an alternative opening possibility exists in a vehicle door. To actuate the locking unit, an actuating unit is used which moves the locking unit out of the locking position into the release position if necessary, for example in the case of a sensed crash, or after setting a specific vehicle position.

The motor vehicle door hinge according to the invention is thus distinguished by the fact that in the event that a pivoting of the connected via the motor vehicle hinge component with respect to the body is not possible, the connection made via the motor vehicle hinge of the component with the vehicle body in an alternative manner by removing the connection of body and coupling element is separable. It is essential that at least one of the two hinge parts, one of which on the vehicle side, d. H. is connected to the vehicle body or the articulated to be connected to the vehicle body component, at least two parts of a base body and a coupling element is formed, which are rigidly arranged in normal operation, however, open in case of need a separability, resulting in a further possibility of displacement of the swivel arranged component relative to the vehicle body results.

The mutually fixed arrangement of the coupling element on the base body in its normal position, can in principle be done in any way. According to a particularly advantageous embodiment of the invention, however, it is provided that projections are arranged on the one coupling element and / or base body, which engage in the normal position in corresponding recesses on the other coupling element and / or base body. Particularly advantageously, these projections can be formed by positioning pins and the wells through correspondingly formed holes.

The use of projections and correspondingly formed recesses, for example. Positioning pins and holes, makes it possible to fix the coupling element particularly reliable in the normal position on the base body, so that in normal operation leading to a failure relative movements of the coupling element against the main body is effectively prevented. The protrusions and depressions allow in the normal position by the positive connection caused by them a particularly reliable fixing of the coupling element to the body.

The motor vehicle hinge according to the invention makes it possible to separate the coupling element from the main body in the release position of the locking unit. The separating movement, wherein the coupling element can be moved relative to the base body, can be generated in any way, with only a simple release is possible, as a result of manual operation of the base body and coupling element are removed from each other. According to a particularly advantageous embodiment of the invention, however, it is provided that the coupling element and the base body are fixed against each other against a bias in the normal position. According to this embodiment of the invention acts in the normal position, a bias, which pushes the base body and coupling element from each other. The locking unit thereby causes the coupling element and the base body against the bias in the normal position are fixed to each other. In the case of a displacement of the locking unit in the release position, the bias then causes an automated separation movement of the coupling element of the body, which is dependent on the amount of bias.

The configuration of the bias can be done in any way. According to a particularly advantageous embodiment of the invention, however, it is provided that the bias voltage is provided by a arranged in the region between the coupling element and the main body spring element, in particular a helical compression spring. According to this embodiment of the invention, the base body and the coupling element in the normal position are preferably set against each other against the bias generated by the helical compression spring. In the case of a displacement of the locking unit in the release position then causes the spring element, For example, the helical compression spring, a relative movement of the base body relative to the coupling element, whereby a separation of the motor vehicle hinge is effected. The use of a spring element, in particular a helical compression spring is characterized in that it provides a particularly reliable bias at very low cost.

The basic definition of the base body on the coupling element in the normal position by the locking unit can be configured in any way, provided that it is ensured that the locking unit is adjustable in a release position in which the coupling element is separable from the main body. According to the invention, it is provided that the locking unit has a locking pin extending through the base body and the coupling element, which abuts in the normal position at one end with a stop element and at the other end with the adjusting screw on an outer surface of the coupling element and base body. The locking unit is adjustable between the blocking position and the release position. In the blocking position, the securing pin fixes the coupling element and the basic body to one another. In the release position of the locking pin relative to the base body and / or coupling element is displaced.

The securing pin has at one end the stop element, which rests against an outer surface of the coupling element or the base body. By the locking unit of the locking pin is fixed in the blocking position such that the coupling element and the base body are fixed to each other. The locking pin rests at one end with the stop element on the outer surface of the coupling element or body and is the other end determined by the screw in the blocking position such that the coupling element and the base body are blocked with respect to a separating movement.

By using a securing pin which can be formed as a tie rod in the form of a bolt extending through the body and coupling element, directed in the longitudinal axis direction of the locking pin separating movement can be blocked in a simple manner, on the one hand the stopper and on the other hand, the screw blocked a separating movement.

The design of the locking unit is basically arbitrary. According to a particularly advantageous embodiment of the invention, however, the locking unit has a in the blocking position on the outer surface of the hinge part and the stop element fitting locking element which is adjustable between the locking pin in the normal position locking position and a locking pin releasing unlocking position. According to this embodiment of the invention, the stop element abuts against a blocking element, which in turn rests against one of the outer surfaces of the hinge part, consisting of base body and coupling element. The position assurance of the stop element on an outer surface of, for example, applied to the coupling element locking element is achieved by the adjusting nut, which rests in this case on the outer surface of the body. The blocking element is adjustable independently of the securing pin between a locking pin defining the locking position and the locking pin releasing unlocking position. In the normal position according to this embodiment of the invention, the coupling element and the base body between the locking element and the stop element on the one hand and the adjusting nut on the other hand fixed.

According to an advantageous embodiment of the invention it is provided that the basically arbitrarily ausgestaltbare blocking element is formed by a locking disc which is adjustable between the locking pin defining the locking position and the locking pin releasing unlocking position. According to this embodiment of the invention, a locking disc is used to lock the locking pin extending through the base body and the coupling element in the normal position. For this purpose, the blocking disk may, for example, have an opening adapted to the stop element, wherein in the unlocking position of the locking disk the stop element is movable through the opening of the locking disk and in the locking position of the locking disk the stop element is fixed by the locking disk relative to the base body and the coupling element.

In principle, the displacement of the blocking element from the locking position into the unlocking position can be effected in any desired manner, with the actuating unit being used for this purpose. According to a particularly advantageous embodiment of the invention However, the actuator unit has an actuator unit for displacing the locking element from the locking position in the unlocking position. The actuator allows by their simple activation, the displacement of an actuating element, which in turn causes by its displacement, a movement of the locking element, through which this arrives from the locking position in the unlocking position. In principle, any actuators, for example magnetically acting, can be used. However, the actuator unit particularly advantageously has a pyrotechnic actuator which is arranged such that an activation of the actuator causes a displacement of the blocking element into the unlocking position. A pyrotechnic actuator is characterized by its high reliability and fast triggering capability. A displaceable by the pyrotechnic actuator bolt, which serves as an actuating element, thereby comes into engagement with the locking element during activation and causes its displacement in the unlocking position.

According to a further advantageous embodiment of the invention, a spring element, in particular a cup spring assembly is arranged between the stop element and the outer surface of the locking element, for example. Such an embodiment of the invention causes a bias of the locking pin in the direction of a separating movement, whereby in the case of a displacement of the locking element in the unlocking rapid separability of body and coupling element is ensured.

The determination of the base body on the coupling element can be fixed in a simple manner via the adjustable by the adjusting nut tightening torque, preferably for this purpose the locking pin in the region of the stop element has a tool holder, for example. In the form of a slot. The tool holder makes it possible to adjust the tightening torque comfortably by means of a screwing tool, for example a screwdriver. Although this already a reliable arrangement can be ensured, it is provided according to an advantageous development of the invention that the adjusting nut is biased in Aufschraubrichtung on the locking pin. The bias ensures a special degree a secure arrangement of the adjusting nut. In addition, the bias causes an automatic adjustment of the adjusting nut in the direction of the blocking position, so that a faulty separation particularly effectively prevented becomes.

The design of the bias of the adjusting nut is basically freely selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the adjusting nut is biased by a leg torsion spring whose first leg with the adjusting nut and second leg with the abutment element opposite end of the locking pin is engaged in such a way that the adjusting nut is biased in the screwing , This embodiment of the invention ensures in a special way a positioning of the screw so that it secures the position of the coupling element and body together, the locking pin acts as a tie rod.

The arrangement of the legs of the leg torsion spring on the adjusting nut and the locking pin is freely selectable. Particularly preferably, however, the first leg is arranged in a bore on the circumference of the adjusting nut and the second leg in a transverse slot at the end of the locking pin. In a particularly simple manner, the tightening torque exerted by the spring on the adjusting nut can be determined via a preferred multiplicity of bores arranged distributed over the circumference, the arrangement itself offering a high level of functional reliability.

A first, in the FIGS. 1 to 3 illustrated embodiment of a hinge part 1a, a motor vehicle hinge, not shown here, which has a hinged to the hinge part 1a, not shown here second hinge part, has a base 2a and a coupling element 3a.

The hinge part 1a is composed of the main body 2a and the coupling element 3a, which in the in Fig. 2 and 3 shown normal position are fixed together. The normal position corresponds to the position of the hinge part 1a, which has this in normal operation of the motor vehicle hinge. For fixing the base body 2a to the coupling element 3a, a locking unit 4a is used, which is adjustable between a locking position in which the base 2a is fixed to the coupling element 3a and a release position in which the base 2a is movable relative to the coupling element 3a.

In the in the FIGS. 1 to 3 illustrated embodiment of the hinge part 1a, the locking unit 4a has a locking pin 10a, which extends in the normal position both through the base 2a and through the coupling element 3a. At one end, the securing pin 10a has a stop element 20a in the form of a web extending perpendicularly to the longitudinal axis of the securing pin 10a. At the other end, an adjusting nut 16a can be screwed onto the securing pin 10a.

In the normal position, the locking pin 10a extends on the one hand through a web opening 13 in the coupling element 3a, wherein the web opening 13 is formed slightly larger than the web, and on the other by a bore in the base 2a. Coaxially with the end of the securing pin 10a opposite the web, a plate spring packet 9 is arranged which is arranged in the normal position of the securing pin 10a between the adjusting nut 16a and a stop surface 14 of the base body 2.

In the normal position, the stop element 20a is further rotated relative to the web opening 13 in the coupling element 3a that the web on the outer surface 14 of the body 2a facing away from the surface of the hinge part 1a, in the present embodiment of the coupling element 3a, is present. About the web-shaped stop element 20a and the adjusting nut 16a, the base body 2a is locked to the coupling element 3a in the normal position. Additional securing pins 6a, which are fastened to the coupling element 3a and extend through holes 7a in the basic body 2a, increase the position security. The plate spring assembly 9 causes a bias of the body 2a in the direction of the coupling element 3a and also causes in the event of a displacement of the locking pin 10a from its locked position into a release position, in which the web is arranged corresponding to the web opening 13 in the coupling element 3, a displacement of the securing pin 10a in the direction of the base 2a.

The pyrotechnic actuator 12 is arranged on the coupling element 3a in such a way that when the pyrotechnic actuator is activated, a bolt 15 engages the web-shaped stop element 20a in such a way that it engages the pin-shaped stop element 20a is rotated in a position in which the web is arranged congruent to the web opening 13.

In the FIGS. 4 to 7 is a second embodiment of a hinge part 1b according to the invention in one FIG. 4 illustrated motor vehicle hinge 37 shown. The hinge part ib shown is, as well as in the FIGS. 1 to 3 formed hinge part 1a, for articulated connection with a further hinge part 30 of the motor vehicle hinge 37 and the arrangement of a vehicle body or a door, hood, flap or the like, not shown here.

Like the hinge part 1a shown above, the hinge part 1b also has a base body 2b and a coupling element 3b. With its further hinge part 3o end facing the coupling element 3b is hingedly connected via a hinge pin 31. By contrast, with the end opposite the further hinge part 30, the coupling element 3b, like the hinge part 1a, is locked to the base 2b via a locking unit 4b in the normal position.

In the normal position, therefore, the base body 2b and the coupling element 3b are included their mutually facing abutment surfaces against each other, wherein in the region between the coupling element 3b and the base body 2b arranged positioning pins 6b for securing the position of the coupling element 3b and body 2b serve each other. The positioning pins 6b are arranged in recesses 7b, 7c provided for this purpose of the base body 2b and the coupling element 3b.

In addition, in the area between the base body 2b and the coupling element 3b, a helical compression spring 8 is arranged coaxially with the securing pin 10b, so that the helical compression spring 8 biases the coupling element 3b and the base body 2b against the normal position. A arranged in the area between the base body 2b and the coupling element 3b aramid foil 21 also serves to seal and prevents noise in the event of unwanted relative movement of the components 2b, 3b to each other.

In order to secure the normal position, the locking unit 4b has the securing pin 10b extending through bores 38a, 38b in the base body 2b and coupling element 3b, which has a stop element 20b at one end and a thread for receiving an adjusting nut 16b at the other end. In the normal position, the stop element 20b bears against a locking disk 11 arranged between the stop element 20b and an outer surface of the coupling element 3b, wherein the securing pin 10b is engaged in a locking position via a radial groove 32 with a round region of an opening 29 of the locking disk 11, such that an axial displacement of the securing pin 10b is blocked. To secure the position of the locking pin 10b, whereby the base 2b is fixed to the coupling element 3b, is further screwed onto the stop member 20b opposite end an adjusting nut 16b, which rests with its the base body 2b facing abutment surface on the base body 2b. To secure the position of the adjusting nut 16b this is biased by a leg torsion spring 24 in the screwing on the locking pin 10b. The leg torsion spring 24 is arranged coaxially with the adjusting nut 16b. A first leg 25 is disposed in a bore 27 on a peripheral collar 34 of the adjusting nut 16b. The second leg 26 of the leg torsion spring 24 is arranged to generate the bias within a transverse slot 28 in the end of the locking pin 10 b opposite the stop element 20 b. About the freely selectable arrangement of the first Leg 25 can be fixed in one of the distributed on the collar 34 of the adjusting nut 16b bore 27, the bias of the adjusting nut 16b.

To arrange a cap 35 above the adjusting nut 16b, the encircling collar 34 of the adjusting nut 16b further comprises a circumferential groove 33 into which the cap engages. In the region of the stop element 22b this and the locking disc 11 is also covered by a cap 36 which engages a shoulder of the locking disc 11.

In order to separate the base body 2b from the coupling element 3b, the locking unit 4b has a pyrotechnic actuator 12b which, in the case of activation, ejects a bolt 15 which engages with the locking disk 11. In this case, it is displaced such that the stop element 20b in the region of the opening 29 with the locking disc 11 is disengaged. The opening 29 of the locking disc 11, through which the locking pin 10b extends, has the edge region over which the stop element 20b and the locking pin 10b are blocked in cooperation with the radial groove 32 in the axial direction. A displacement of the locking disk 11 by the actuator 12 causes a displacement of the opening 29 such that the locking disk 11 is disengaged from the radial groove 32, so that the locking pin 10b moves in the direction of the adjusting nut 16b through the base body 2b and the coupling element 3b, respectively The coupling element 3b can be lifted off the main body 2b.

To guide the locking disk 11, this guide elements 22, which are guided in guide element receivers 23 on the coupling element 3b. Separate guide elements can thus be dispensed with. An adjusting movement of the locking disc 11 from the locking into the unlocking position is predetermined by the guide elements 22 and the guide element receptacle 23.
