Description

The invention relates to a vehicle according to the preamble of claim 1 with a convertible vehicle roof having a front roof part and a rear roof part, which between a vehicle interior overlapping the closed position and the vehicle interior releasing storage position in which it is lowered in a rear storage compartment of the vehicle are, are adjustable. Such a vehicle is, for example, a convertible with an adjustable hardtop roof. The invention further relates to a drive device for at least two movable roof parts of a vehicle roof.

From the DE 10 2004 050 514 A1 is such a vehicle with a convertible roof has become known, the front roof part and rear roof part are pivotable about two body-mounted pivot axes in a storage space extending behind the seats and in which the two roof parts lying one above the other in an approximately 180 ° relative to the closed Position rotated position are stored. The cabriolet vehicle shown is two-seater. The two roof parts are designed to be correspondingly short, so that the front roof part can be mounted directly behind the seats laterally on the body pivotally. The movement of the two roof parts is preferably carried out by a common electric or hydraulic drive via gears or toothed segments.

From the DE 299 13 486 U1 is a convertible vehicle with a convertible vehicle roof has become known, for example, the three roof parts are each pivotally mounted on different body-mounted main bearings. The vehicle roof comprises moving units associated with each main bearing, which are forcibly synchronized with each other for a common opening and closing movement by means of a positive coupling. A drive acts on the movement unit of the central roof part. The drive movement is transmitted via the positive coupling to the other roof parts.

The invention has for its object to provide an aforementioned vehicle, the movable roof parts can cover a larger vehicle interior with two rows of seats arranged one behind the other and can be adjusted with simple storage and easy executable movement between the closed position and the open position of the vehicle roof. Another object is to provide an improved drive device for at least two movable roof parts of a vehicle roof.

The object is achieved by a vehicle with the features of claim 1. Characterized in that the rear roof part is pivotally mounted by means of a coaxially arranged to a body-side main bearing bearing means, the front roof part is pivotally mounted by means of a multi-joint arrangement on the rear roof part, and a drive lever for the multi-joint arrangement of the front roof part by means of a coaxial with the body-side main bearing arranged bearing means pivotally is stored, results in a particularly simple movement of the roof parts. As a result of the invention, the advantage of a common drive for both roof parts can also be used in a vehicle with two rows of seats arranged one behind the other in the direction of travel. The further object is achieved by a drive device having the features of claim 14.

Advantageous embodiments of the invention are specified in the subclaims.

It when the common drive at two different output members provides two different speeds of movement for the pivotal movements of the two roof parts between the closed position and the storage position is particularly advantageous. The pivoting movements can then take place simultaneously as far as possible, wherein the rear roof part is driven at a slightly lower speed of movement and moves relative to the front roof part so that collisions of both roof parts are avoided. The beginning as well as the end of the pivoting movements of the two roof parts can take place simultaneously, but it is also possible according to an alternative embodiment, a slightly offset movement of the output members in time. In this design can be dispensed with a complex control device. A malfunction with a possible risk of collision of the two roof parts is forcibly avoided in a simple manner by the design of the kinematics.

In addition to a coaxial arrangement of the two pivot axes of the rear and front roof part and a spaced-apart arrangement of the parallel pivot axes of the roof parts is possible. The output members of the common drive are not arranged coaxially in this case, but can be connected by appropriate transmission elements, such as chains, belts, Bowden cables or racks, with the common drive. Preferably, because the simplest in the design, however, is an embodiment with a coaxial arrangement of the two pivot axes of the rear and front roof part and the two associated output members of the common drive.

Preferably, the kinematics is designed such that in the storage compartment, the front roof part is arranged above the rear roof part, so that first pivot the rear roof part and then the front roof part in the storage space.

The pivot angle of the front roof part and the rear roof part is in the range of about 180 °, when the two roof parts are aligned in the closed position in approximately horizontal and are also arranged in the storage compartment in the pivoted position about horizontal. In case of deviating design of course, the swivel angle can vary accordingly.

It is preferred if a drive device for adjusting the two roof parts with both the front roof part as well as with the rear roof part in drive connection, but also each roof part - especially in a non-coaxial arrangement of the pivot lever for the rear roof part and the drive lever for the front roof part - be coupled with its own drive, these drives coordinated by a common control device cause the simultaneous pivoting movement of the two roof parts.

A simple preferred embodiment provides that the bearing device of the rear roof part and the bearing device for the drive lever of the front roof part each have a gear or a toothed segment of different diameters or different numbers of teeth, which is arranged on the pivot bearing and with the bearing device for the drive lever of the front roof part or the pivot lever of the rear roof part is rotatably connected, and that the drive means for adjusting the two roof parts by means of at least one drive gear with both gears or the tooth segments is simultaneously in driving engagement, wherein the drive gears of the drive means in the diameter or in the number of teeth are designed vice versa , That is, to produce a slower moving speed for the pivot lever of the rear roof panel, the drive gear has a smaller diameter on the drive than the drive gear of the drive lever for the front roof part and the gear or toothed segment associated with the pivot lever of the rear Coupled roof part is a larger diameter or a larger number of teeth than the gear or toothed segment for the drive lever of the front roof part. This mechanical coupling can transmit the required driving forces in a very small space.

The drive device for adjusting the two roof parts may comprise a hydraulic cylinder, an electric motor or other suitable drives. The drive device can also be connected via a transmission element such. As an idler gear, a chain, a toothed belt, a flexible rack or a tension and pressure-tight guided Bowden cable with the gears or toothed segments for the actuation of the two roof parts to be coupled.

The two roof parts preferably contain fixed roof shells (in this case referred to the vehicle roof as "Retractable Hardtop" or abbreviated as "RHT2" (fixed element convertible with two movable roof parts)), in principle, frame structures with a string (in this case, one speaks of a "Soft top convertible" or mixed forms of both types.

Conveniently, a lid of the storage compartment or top compartment lid is pivotally mounted in the region of its rear edge on the vehicle and swung up before the pivoting of the roof parts with its front edge in an open position.

A convertible vehicle 1000 (please refer 1 ) contains a movable and can be lowered for opening vehicle roof 1 between a vehicle interior 4 overlapping closed position ( 1 . 2 and 7 ) and an open position ( 6 and 9 ) is adjustable, in which it in a rear-side storage compartment or convertible top compartment 8th is stored. The vehicle roof 1 is according to the illustrated embodiment, a movable hardtop with a front roof part 10 and a rear roof section 20 , The roof parts 10 . 20 are arranged in the closed position one behind the other and are designed as rigid roof shells.

Basically, the vehicle roof 1 however, it may also be a soft top roof, with the front and rear roof sections 10 respectively. 20 wear a top cloth, or the vehicle roof 1 is a hybrid of hardtop roof and softtop roof, ie the z. B. the front roof part 10 is designed as a rigid roof shell, while the rear roof part 20 is formed as a soft part from covered with a top cloth straps or frame.

All the levers, bearings or actuators described below are always symmetrical to a central longitudinal axis of the vehicle 1000 present on both sides of the vehicle, even if in the following only in the singular arrangement on a vehicle side is described.

At the in the closed position of the vehicle roof 1 rear roof section 20 closes a soft top compartment lid 6 of the top compartment 8th on, by means of a pivot lever 9 around a rear warehouse 90 is pivotally mounted and with its front edge for releasing a passage opening for the vehicle roof 1 around this camp 90 is swung up so that the vehicle roof 1 in the top compartment 8th can be pivoted or swung out of it. The warehouse 90 can be fixed to the body and z. B. be formed by a hinge in the form of a hinge or it is z. B. formed by a four- or multi-joint and shifts during pivoting of the top compartment lid 7 relative to the body.

The top compartment 8th can, as shown, be a separate storage space in the rear of the vehicle, but it can also serve as a storage room for the roof parts 10 . 20 as part of a not shown rear trunk of the vehicle 1000 preferably be separable by means of a movable partition of this.

The front roof part 10 is by means of a in the closed position of the vehicle roof 1 according to 1 . 2 or 7 rearwardly projecting multi-joint arrangement, in the embodiment shown in the form of a four-bar arrangement with two levers 50 respectively. 60 swiveling on the rear roof part 20 hinged. The front roof part 10 has a console 100 on, in the closed position of the roof 1 a rearward fixed extension of the front roof section 10 forms. At this console 100 is the lever 50 with a warehouse 150 and slightly spaced back to the other lever 60 with a warehouse 160 hinged pivotally.

The articulation of the lever 50 at the rear roof part 20 takes place at a warehouse 250 and the articulation of the other lever 60 takes place at a warehouse 260 , both bearings 250 . 260 on one fixed to the rear roof part 20 connected bearing lever 255 the rear roof part 20 are arranged.

The multi-joint arrangement with the levers 50 and 60 is by means of a lever 70 and a lever 80 existing toggle lever assembly or toggle assembly actuated. The lever 70 is by means of a linkage 760 on the lever 60 pivotally mounted, with the linkage 760 the lever 60 in about 2/3 to 1/3 proportion and the shorter of these two distances from the linkage 760 to the camp 260 at the rear roof part 20 extends.

The lever 70 is at a joint 780 with the lever acting as a drive lever 80 connected. The lower end of the drive lever 80 is at a main warehouse 30 rotatable on the body of the vehicle 1000 at the height of the C-pillars just above the waistline 3 of the vehicle 1000 stored. With the lower end of the drive lever 80 is coaxial with the main bearing 30 a gear or toothed segment 380 firmly connected.

The rear roof part 20 is at its rear end with a tilted down crank lever 210 firmly connected. The as well as all other mentioned levers and actuators symmetrical to the central longitudinal axis provided on both sides of the vehicle pivot lever 210 can directly form the C-pillars of the vehicle and accommodate between them a rear window, not shown. The swivel lever 210 is with its lower end at the main camp 30 rotatably mounted in a coaxial arrangement to this. With the lower end of the pivot lever 210 is a gear or toothed segment 321 rotatably connected, which also coaxial with the main camp 30 is arranged.

With the gear or toothed segment 380 at the lower end of the drive lever 80 is a gear or toothed segment 480 engaged, the below the camp 30 rotatably mounted on the body of the vehicle and by a only in 5 illustrated drive 41 is movable. The example designed as a pinion output member of the drive 41 generated in the area of the drive axle 40 coaxial with the gear or sector gear 480 at the main camp 30 is arranged, a rotational movement of the gear or toothed segment 480 ,

With the gear or toothed segment 321 at the lower end of the pivot lever 210 is a gear or toothed segment 421 engaged, that underneath the main bearing 30 in the area of the drive axle 40 is rotatably mounted. The gears or tooth segments 421 and 480 can be firmly coupled to the drive.

Optionally, a coupling of these gears or tooth segments by means of a movable perpendicular to the plane coupling element, for example in the form of a locking block only in a certain phase of movement possible, so that, for example, at the beginning of the opening movement in a first movement phase by means of the drive 41 only the gear or toothed segment 421 for the operation of the rear roof part 20 is moved to the rear roof part 20 initially at a certain distance from the front roof part 10 bring to. During this first movement phase, the second gear or toothed segment 480 for the operation of the front roof part 10 not yet from the drive 41 taken. In a second phase of motion, a bolt locks the gear or toothed segment 421 with the gear or toothed segment 480 , whereby in the second movement phase, a simultaneous movement of the second roof part 20 and the first roof part 10 takes place. In a third movement phase, in which the rear roof section 20 its final position in the top compartment 8th has already reached, then in turn a decoupling of the toothed segment 421 from the toothed segment 480 done so that in this third movement phase only the front roof part 10 is pivoted to its final position.

The variant described above represents only one option for a phased sequential actuation of the roof parts 10 respectively 20 In the preferred embodiment according to the embodiment shown are both connected to the drive gears or tooth segments 421 and 480 permanently connected to each other and to the drive. However, the gears or tooth segments differ in diameter or in their number of teeth, so that the gear or toothed segment 421 has a smaller diameter or a smaller number of teeth and in conjunction with the meshing gear or toothed segment 321 on the pivot lever 210 for a smaller translation and thus a lower operating speed of the rear roof part 20 provides.

The coupled with the drive other gear or toothed segment 480 points opposite the gear or toothed segment 421 a larger diameter or a larger number of teeth and generated in conjunction with the meshing gear or toothed segment 321 a larger translation and thus a higher operating speed of the drive lever 80 and thus the front roof part 10 , Thus, the transmission ratio d ₄₈₀ / d _{380 of} the front roof part 10 greater than the transmission ratio d ₄₂₁ / d _{321 of} the rear roof part. Instead of the diameter ratios d ₄₈₀ / d ₃₃₀ and d ₄₂₁ / d ₃₂₁ , the corresponding ratios of the number of teeth can be used analogously.

In the embodiment shown, a simultaneous movement of both roof parts takes place 10 respectively 20 with different speeds of movement without causing collisions. The rear roof part 20 is in closed position (see 2 ) from behind at the trailing edge of the front roof part 10 at. It moves at the transition from the in 2 shown closing position in the in 3 Partial opening position shown sufficiently quickly from the front roof part 10 away, so that it does not oppose its pivoting movement.

At the end of the opening movement both roof parts reach 10 . 20 preferably together the opposite to the closed position (see 1 ) by about 180 ° rotated storage position in the top compartment 8th (please refer 6 and 9 ), the front roof part 10 in the opposite to the closed position (see 1 ) rotated by 180 ° storage position above the rear roof part 20 in the top compartment 10 is filed.

By the leverage of the lever 50 and 60 , the position of the linkage 760 as well as the leverage of the levers 70 and 80 is the kinematics for operating the front roof part 10 designed in the way that the rear roof part 20 at the beginning of the opening movement of the front roof part 10 moved away so as not to block its movement, and the front roof part 10 towards the end of the opening movement relatively close to the rear roof part 20 unlocks and thus synchronous to this in the top compartment 8th is filed.

Alternatively, an arrangement is possible in which the tooth segments 421 and 321 after reaching the end position of the rear roof part 20 in the top compartment 8th disengaged and located in the subsequent final phase of the opening movement still engaged gear segment pair 480 . 380 the front roof part 10 moved alone to its final storage position.

However, an embodiment in which all gears or tooth segments is advantageous 321 . 380 respectively. 421 . 480 remain permanently coupled to the drive. Such an embodiment provides a robust and simple mechanism that is free of any coupling elements or superordinate control devices.

As a drive 41 for the drive gear or tooth segment 421 . 480 For example, an electric motor or a hydraulic cylinder is provided, which is connected directly or via a gear and / or a transmission element with these. The drive 41 can with its output member an integral unit with the drive gears or tooth segments 421 . 480 form.

In the storage compartment or convertible top compartment 8th lies the front roof part 10 in tilted position with its top facing down over the rear roof section 20 , which is also swung around and below the front roof part 10 to come to rest. The soft top compartment lid 7 Finally, it is lowered again and covers the folded vehicle roof 1 with the roof parts 10 respectively 20 containing storage compartment or convertible top compartment 8th from (analogous to in 1 shown closed position of the top compartment lid 7 ).

Basically, on the front roof part 10 as well as on the rear roof part 20 nor an additional roof part fixedly mounted or movably mounted and adjusted in particular synchronous storage movement with the associated roof part, wherein also here the drive movement is advantageously derived from the one drive device.

In a vehicle roof 1 With three movable roof parts of the common drive can be by three preferred provided by Zahnräder- or toothed pair pairs different ratios all three roof parts simultaneously with different speeds in a convertible top compartment 8th move.

In the opened state of the vehicle roof 1 is at the same time shut down side windows of the entire vehicle interior 4 above the belt line 3 of the vehicle exposed. From the front screen 2 laterally delimiting A-pillars 5 stay behind only the arranged behind the front row of B-pillars 6 stand as a roll bar, which also optionally in the opening position of the vehicle roof 1 in the body of the vehicle 1000 can be designed to be retractable and extend in the event of a crash in milliseconds as a roll bar.
