Description

The The invention relates to a vehicle roof with a movable roof part according to the preamble of claim 1.

From the DE 10 2006 032 700 B3 is a vehicle roof with a connection of a movable roof part to a release lever of a mechanism known. The roof part is fastened there to a bolt, which in turn is rotatably mounted in a bearing eye of the deployment lever. The connection shown only works flawlessly in the case of a network-parallel, straight-line cover guide. In the case of deviations from the parallelism, a torque acts at the attachment point, which leads either to blocking the movement by tilting or to fatigue and, in the worst case, to the breakage of the connection.

• – Auf Grund der auftretenden Kräfte bei seitlicher Beschleunigung und bei vertikaler Beschleunigung (Rütteln) sind die mechanischen Komponenten entsprechend groß zu dimensionieren. Die vielen Gelenke brauchen entsprechend viel Bauraum.
• – Die Führung in Fahrzeugquerrichtung erfolgt über Stangen, die zueinander verschiebbar sind. Dies bedeutet, dass sie horizontal geführt sein müssen und demzufolge einer Dachquerwölbung nicht folgen können. Auf Grund dessen wird in Fahrzeugmitte vergleichsweise viel Bauhöhe benötigt.
• – Die Lagerverhältnisse bedingen, dass das hintere Gelenk in Fahrzeugquerrichtung über die äußere Führungsschiene hinaus nach außen ausgezogen wird. Je weiter das Gelenk seitlich über die äußere Führungsschiene hinaus steht, desto größer ist die angeströmte Fläche und desto größer sind die zu erwartenden Windgeräusche.
• – Die Schubstangen belegen Bauräume, die im Normalfall von den Deckel versteifenden Elementen gebraucht werden. Wenn diese neben den Schubstangen angeordnet werden, verschlechtern sich bei einem Glasdeckel die Durchsichtsverhältnisse. Werden keine zusätzlichen Deckelversteifungen im Bereich der Schubstangen vorgesehen, wird die Deckelsteifigkeit reduziert.

From the DE 101 43 823 A1 is a vehicle roof with a guide of the mechanism in at least partially non-parallel guide rails known. In this an openable roof part is articulated on both sides in each case by means of a multi-joints comprehensive lever mechanism on a sliding sliding element comprehensive in the guide rails Ausstellmechanik. This mechanism has the following disadvantages:

• - Due to the forces occurring in lateral acceleration and vertical acceleration (shaking), the mechanical components are sized accordingly large. The many joints need a lot of space.
• - The leadership in vehicle transverse direction via rods that are mutually displaceable. This means that they must be guided horizontally and therefore can not follow a Dachquerwölbung. Due to this, comparatively much height is required in the middle of the vehicle.
• - The bearing conditions require that the rear joint is pulled out in the vehicle transverse direction beyond the outer guide rail to the outside. The farther the joint is laterally beyond the outer guide rail, the larger is the surface area and the greater the wind noise to be expected.
• - The push rods occupy installation space, which are normally used by the lid stiffening elements. If these are arranged next to the push rods, the transparency of a glass lid deteriorates. If no additional lid stiffeners are provided in the area of the push rods, the lid rigidity is reduced.

Of the Invention is based on the object, a vehicle roof with a simplified, less space requiring, parallelism deviations of Guides balancing articulation of the roof part at the To create mechanics.

These The object is achieved by the features of claim 1. Advantageous embodiments The invention are specified in the subclaims.

The The invention provides, in essence, that the joint of the attachment device at least one ball head and at least one complementary Shaped receptacle (ball socket) for rotatably supporting the Includes ball head with at least two degrees of freedom. By a Such connection will require several previously required joints and Rods replaced by a single joint, creating valuable space won and the costs can be reduced considerably.

According to one advantageous embodiment of the invention, the ball head is at one while the component connected to the roof part, while the recording is provided on a lever of the mechanism.

The Recording may be preferred as a ball socket directly on the lever of the mechanism molded or formed as a separate molded part and the lever be attached.

at a separate embodiment of the ball socket containing bearing part it is advantageous if this bearing part against the Lever in its position - especially in the direction of Vehicle height - is adjustable. This adjustability can through a slot with a clamping screw or according to an alternative by an eccentric Arrangement of the ball socket on the bearing part and a rotatable arrangement of the bearing part can be achieved on the lever.

Of the Ball head is preferably on a piston rod of a hydraulic Arranged cylinder, which is part of a balancing device, the below the movable roof part transverse to the vehicle longitudinal direction is arranged.

The Compensating device preferably comprises at least two means a hydraulic fluid acted upon cylinders on opposite Pages are arranged on the movable roof part and by means of two transverse to the guide rails movable piston rods with the mechanics are connected for moving the roof part. Such Hydraulic balancing device requires little space and is also an adaptation to a transverse curvature of the Roof part not contrary. She worked independently and Maintenance-free and automatically dampens any vibrations that occur.

Advantageous The hydraulically actuated cylinders each have over an outer chamber and an inner chamber, the by a piston connected to the piston rod from each other are separated.

According to one particularly preferred embodiment is one each Inner chamber of a first cylinder on one side of the roof part via a Equalization line or via a balancing reservoir with an outer chamber of a second cylinder connected to the opposite side of the roof part.

According to one first alternative, the cylinders are each individually on opposite Pages of the roof part arranged, and an inner chamber of the one Cylinder is by means of a compensation line with the outer Chamber of the other cylinder connected.

According to one second alternative are the cylinders on opposite Sides of the roof part in a common tubular Housing arranged, and an inner chamber of the one cylinder is arranged by means of a between the cylinders in the housing Balancing reservoir with the outer chamber of the connected to another cylinder. By the arrangement in a common Pipe can be the equalizer before mounting on the roof part completely pre-assembled and tested. Advantageously used the tubular housing at the same time the stiffener the movable roof part at the relevant edge. The tubular Housing can also be used as part of a system of im Edge region below the roof part arranged cover inner plates be integrated into this system. The attachment can - like for cover inner plates usual - through Screwing, gluing or by joint foaming done with a glass of the roof part.

For a good plant and an adaptation to the shape of the underside of the movable roof part, it is advantageous if the tubular Housing on its top side facing the roof part a flattening and / or when the tubular housing in its contour to a transverse curvature of the movable roof part is adjusted.

Prefers the cylinders are on the not acted upon by the hydraulic fluid Side of the piston provided with a spring. This will cause the hydraulic fluid opposite to a slight counterforce when overflowing, the additional damping and elimination causes a hysteresis.

The Spring is according to a first variant of a formed mechanical pressure spring. Alternatively or in addition For this purpose, the spring may also be opposed to one in the hydraulic fluid Chamber of the respective cylinder by trapped air there be formed formed air spring.

This in 1 shown vehicle roof 10 has from front to back one behind the other lying next to a cowl above the windscreen 12 arranged, with its trailing edge exhibitable Windabweiserlamelle 14 , a movable roof part 16 and a rear fixed roof part 18 on. The preferably formed in the form of a lid made of glass movable roof part 16 is by means of a mechanism with its trailing edge 1620 in a fan position and optionally starting from this on the fixed roof part 18 slidable to the rear, with a roof opening 20 is largely uncovered and wherein the movable roof part 16 in contrast to conventional, also referred to as spoiler roofs lifting-sliding roofs also in its displacement to the rear (in the dashed lines with 16A designated position) always near its trailing edge 1620A is supported.

Such as from the DE 10 2005 007 031 A1 known openable vehicle roofs are referred to as outer sliding sunroof (ASD), as a the trailing edge of the lid 16A supporting part of the mechanism, namely a release lever or an additional support lever (as in the EP 0 863 817 B1 ) in a to the top of the vehicle roof 10 open roof-fixed leadership 24 slidably supported. A detailed description of the general structure of the rear part of the mechanism of the movable roof part 16 is the DE 10 2005 007 031 A1 can be removed, the disclosure of which is hereby incorporated into the content of the present application.

In the 1 arranged above the cowl, not shown Windabweiserlamelle 14 is only optional. It can also be replaced by a narrower wind deflector, which swivels at the front edge of the roof opening 20 is stored and after partial opening of the movable roof part 16 upwards over the vehicle roof 1 is issued and thus the wind is largely free of noise on the shared roof opening 20 passes.

The roof opening 20 is at the front of the cowl or the optionally overlying wind deflector plate 14 , to the rear of the fixed roof section 18 and on both sides of one side rail each 22 limited to the vehicle. At the side rails 22 or at one the roof opening 20 on the inside surrounding roof frames are guide rails 26 arranged. Due to the in 1 well-visible waisted contour of the vehicle roof 10 and thus also the movable roof part 16 , which is wider at the front than at the back, have the guide rails 26 front (in 1 left adjacent to the trailing edge of the cowl) at a greater distance than near the trailing edge 1620 the roof opening 20 ,

The back part 24 the guide rails, in which the rear linkages 1640 of the movable roof part 16 are guided in the displacement to the rear, is arranged parallel to each other in the illustrated embodiment, but also according to an alternative also with non-parallel guide rails 24 be provided. In this case, the roof part is not only near its leading edge 1610 , but also in the area of rear linkages 1640 with a compensating device described below 30 (according to 2 to 4 ) respectively. 130 (according to 5 ) Mistake.

The balancing device 30 exists in the first embodiment according to 2 of two by means of a hydraulic fluid 66 acted upon cylinders 32 respectively. 52 according to 1 near the front two corners of the movable roof part 16 are arranged below it. The first cylinder 32 has an outer chamber 34 and an inner chamber 36 on top of a sliding piston 38 be separated. To the outside of the roof part 16 out is on the piston 38 a piston rod 40 arranged sealingly through the outer end wall of the outer chamber 34 is slidably guided through. Outside the outer chamber 34 is on the piston rod 40 a ball head 42 arranged, like, out 2 and 3 visible, with a storage 74 on a lever 72 the mechanics of the movable roof part 16 is articulated. The lever 72 is pivotable with its lower end with a sliding element 70 connected in the guide rail 26 slidably guided in the longitudinal direction of the vehicle. Warehousing 74 with the ball head 42 forms the actual subject of this patent application. It is also referred to below as a connection device 200 and will be described in detail below.

The outer chamber 34 is optional with a spring 35 provided in the embodiment shown, the fluid pressure of the hydraulic fluid 66 in the inner chamber 36 counteracted. On the side of the inner chamber 36 is on the piston 38 a piston rod 44 attached to the inner end wall of the second cylinder 32 sealingly penetrates. The inner chamber 36 is over an entrance opening 46 with a hydraulic equalizing line 48 connected. The other end of the hydraulic equalization line 48 is over an entrance opening 68 with an outer chamber 54 of the second cylinder 52 connected according to 1 near the opposite front corner of the movable roof part 16 is arranged. The system of inner chamber 36 , Compensation line 48 and outer chamber 54 is a closed hydraulic system that is completely and bubble free with the hydraulic fluid 66 is filled.

The second cylinder 52 also has one re chamber 56 on, from the outer chamber 54 by a displaceably mounted piston 58 is disconnected. On the piston 58 is on the lateral outer edge of the movable roof part 16 lying side an outer end wall of the outer chamber 54 sealingly penetrating piston rod 60 with a ball end disposed at the extreme end 62 appropriate. The ball head 62 serves as the ball head 42 for movable articulation of the roof part 16 at a not shown, the mechanics in the 3 and 4 mirror-symmetrical arrangement of a sliding element 70 and a lever pivotally hinged thereto 72 ,

On the side of the inner chamber 56 is on the piston 58 a piston rod 64 attached to the inner end wall of the second cylinder 52 sealingly penetrates. In the inner chamber 56 can be analogous to the outer chamber 34 of the first cylinder 32 a compression spring 35 be arranged, or that in the inner chamber 56 trapped air can, as shown in the embodiment, directly as a compressible air spring 55 serve. Such an air spring can of course also the compression spring 35 in the outer chamber 34 of the first cylinder 32 replace.

In the areas where the guide rails 26 have a greater distance from each other, ie in the illustrated embodiment according to 1 in the front area of the roof opening 20 , are the piston rods 40 and 60 further from the first cylinder 32 or the second cylinder 52 extended. In this case there is more hydraulic fluid 66 in the inner chamber 36 while the outer chamber 34 against the pressure of the spring 35 is compressed and has only a small volume. On the other side, the inner chamber points 56 on the second cylinder 52 a relatively large volume while the outer chamber 54 has a relatively small volume. Because of that, the first cylinder 32 and the second cylinder 52 have the same diameter, flows during a movement of the piston rods 40 respectively 60 exactly the same amount of pressurized fluid 66 from the outer chamber 54 on the side of the second cylinder 52 into the inner chamber 36 on the side of the first cylinder 32 and vice versa.

The balancing device 30 is a passive hydraulic balancer, as the forces for displacement of the piston 38 respectively 58 from the outside on the mechanics with the sliding elements 70 and the levers 72 and over the ball heads 42 respectively 62 be introduced into the system. The balancing device 30 provides by the overflow of hydraulic fluid 66 only a synchronous movement of both pistons 38 respectively 58 safe and thereby ensures a centered movement of the roof part 16 in all phases of movement.

If the roof part 16 from the in 1 shown in solid lines closed position in the direction of the opening position shown in dashed lines 16A is moved by the mechanics on the lever 72 lateral forces inside on the ball heads 42 respectively 62 exercised. The piston rod 40 presses the piston 38 inward and thereby displaces from the inner chamber 36 of the first cylinder 32 hydraulic fluid 66 over the equalization line 48 into the outer chamber 54 of the second cylinder 52 where this ensures that the piston 58 synchronous to the piston 38 pressed inwards.

In the second embodiment according to 5 are all the same or similar parts to the first embodiment with a order 100 provided with a higher reference number. In contrast to the first embodiment, the first cylinder 132 and the second cylinder 152 not separately at the bottom of the roof part 16 arranged, but together in a tubular housing 150 , The tubular housing 150 extends almost over the entire width of the roof part 16 and can - though in 5 just shown - also on a transverse curvature of the roof part 16 be adjusted. The cylinders 132 and 152 , according to their construction basically the cylinders 32 and 52 of the first embodiment.

In contrast to the first embodiment, the inlet opening 146 to the inner chamber 136 of the first cylinder 132 and the entrance opening 168 to the outer chamber 154 of the second cylinder 152 not connected to each other via a separate equalization line, but stand with the entire interior of the tubular housing 150 in conjunction, between the cylinders 132 and 152 a hydraulic fluid balance reservoir 148 forms. The balancing reservoir 148 becomes outward through an end wall 133 and on the other side by an end wall 153 completed. The front wall 133 stores the first cylinder 132 and the front wall 153 the second cylinder 152 so that between the outer surface of the cylinder 132 respectively. 152 and the inner circumferential surface of the tubular housing 150 a distance remains, which is the inflow and outflow of the hydraulic fluid 166 over the entrance opening 146 to the inner chamber 136 of the first cylinder 132 and over the entrance opening 168 to the outer chamber 154 of the second cylinder 152 allows. The inner chamber 136 , the equalization reservoir 148 and the outer chamber 154 form a closed hydraulic system that is completely and bubble-free with the hydraulic fluid 166 is filled.

The inwardly pointing piston rods 144 respectively 164 are opposite the equalization reservoir 148 through a housing 145 respectively. 165 on the first impression cylinder 132 or on the second impression cylinder 152 shielded so that the piston rods 144 . 164 can move without hydraulic resistance.

The function of the first cylinder 132 and the second cylinder 152 during a movement of the sliding elements 70 along the non-parallel guide rails 26 corresponds to the first embodiment. Will at a narrowing distance of the guide rails 26 on the ball head 142 exerted an inward force, so pushes the piston rod 140 the piston 138 to the right and displaces hydraulic fluid 166 from the inner chamber 136 of the first cylinder 132 in the compensation reservoir 148 , At the same time, over the inlet opening 168 hydraulic fluid 166 from the balancing reservoir 148 into the outer chamber 154 of the second cylinder 152 pressed, causing the piston 158 synchronous to the piston 138 is moved inwards. In the outer chamber 134 of the first cylinder 132 and in the inner chamber 156 of the second cylinder 152 can be arranged in each case analogous to the first embodiment, a spring which counteracts the fluid pressure. This spring can be used as a mechanical compression spring or as an air spring in the form of in the chambers 134 respectively. 156 be formed trapped air.

As in 6 shown is the housing 150 at least in the middle area at its top with a flattening 151 provided that a flat attachment and attachment to the underside of the roof part 16 allows.
