Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an actuating mechanism having at least two links which are displaced in time and at different speeds and which are driven by an actuating mechanism connected to a single thorn drive. The present invention relates to a vehicle roof with a covering device which closes the roof opening in the closed position.

(Prior art and problems to be solved by the present invention) In the case of this type of known vehicle roof (West German Publication No. 3.21)
1.519), a so-called spoiler roof is provided with a cover above the fixed roof surface whose trailing edge can pivot and which can be moved rearward in the pivoting state.
The front pivot axis of the cover is supported on a slide that is slidably guided in the longitudinal direction of the vehicle, and for pivoting the cover can be pivoted about a fixed axis in the area of the side edges of the roof opening. An elevating lever is provided with one end pivotally supported and the other end pivotally connected to a sliding member that is slidable in the vertical direction of the cover.

The primary drive is drivingly coupled to a threaded cable that displaces the drive block in the longitudinal direction of the vehicle.

The drive block can be coupled via a clutch that automatically engages and disengages to a push rod that pivots the lifting lever via a slider or groove guide that supports the front pivot axis of the cover, or the above-mentioned member can be separated from The clutch and the parts of the actuating mechanism cooperating with this clutch are located in the side region of the roof frame, which is exposed and becomes visible when the cover is opened, i.e. in the exposed region of the roof and is therefore free from contamination. , subject to corrosion and severe wear and tear. Known solutions are characterized by a relatively expensive construction, in particular for slow lifting operations of the cover and for faster sliding operations than lifting operations, in which the various movement courses are optimally matched to each other with respect to their speed. It is actually impossible to do so.

The screw cable and the cover sliding/lifting device can be connected and disconnected via a clutch, and when the first drive cable is disconnected from the cover lifting device when the cover is slid, the first drive cable is connected to the cover lifting device. Also in the case of another known spoiler roof, in which the two-screw cable is driven by the cover (
(West German Patent No. 2°942,006), a similar problem exists.

The invention provides a vehicle roof of the type mentioned at the outset, with a relatively simple, reliable and robust drive, which allows the movements of the cover device in each operating phase to be speed-coordinated as required. It is about creation.

Means for Solving the Problem This object, according to the invention, is driven by an actuating mechanism connected to a single primary drive, having at least two links displaced in time-staggered and different speeds. In the vehicle roof with a cover device that closes the roof opening in the closed position, an input shaft and, depending on the connection position of the distribution transmission, a transmission element between the primary drive and the displaced link. This is achieved by providing a distribution transmission having at least two output shafts which can be driven separately or together with different transmission ratios via the transmission elements and which can be switched at a predetermined relative position of the transmission elements.

(Function) Hereinafter, the function of the embodiment shown in FIGS. 1 to 9 will be explained.

To explain the function of the distribution transmission 20, the switching knob 95
Assume that the slider 99 is in the position of FIG. 8, ie, the locking mechanism 88 is loaded downwardly by the spring 93, but the slits 83, 84, 85 are not aligned with each other. When the cover 3 is pivoted from the closed position (FIG. 1) to a position just before reaching the raised position (FIG. 2), the noses 89, 90 respectively touch the flanges 82, 8 from above.
1, and therefore, the sliding movement of the fixing mechanism 88 by the spring 93 is prevented. The nose 90 engages in the slit 83 of the external gear 62.During the rotation of the manual crank 22, the planetary gears 60, 64 shift within the external gear 62, which is prevented from rotating by the locking mechanism 88. The planetary carrier 67 and the output shaft 18 are rotationally driven by the upper planetary gear 64 with respect to the rotation of the input shaft 21 at a gear ratio of approximately 3=1, for example. Since the external gear 62 is locked, the other output shaft 19 does not rotate. The cover 3 is pivoted by the screw cable 13.13', while sliding of the cover is prevented by the screw cable 14.14'. Reached the raised position (Fig. 2) and reached the sulin) 83.8
When 4°85 is aligned, the spring 93 pushes down the locking mechanism 88 so that the nose 89 reaches below the flange 82 and the nose 90 reaches below the flange 80. Nose 9
0 releases the external gear 62 and instead engages the slit 84 of the planet carrier 57. Further rotation of the input shaft 21 drives the pinion 16 with a gear ratio of about 8:1, and the pinion 17 with a gear ratio of about 1:1, for example. Thus, the slider 12 is slid at a relatively high speed as described above, and at the same time, the elevating lever 4 is rotated at a slow speed. The cover 3 can be moved to the position shown in FIG.

In the next step, when rotating the crank 22 in the opposite direction to move the cover 3 from the open position (Fig. 3) to the closed position (Fig. 1), displace the slider 99 and move the switching knob 95
6 along the running slope 100.

Spring 93 thus drives locking mechanism 88 axially upward. This upward movement is stopped when the nose 89.90 abuts the underside of the flange 80.82. As soon as the slits 83, 84, 85 coincide in the cover position of FIG. 2, the locking mechanism 88 is flipped up. Thus, once again the external gear 62 is blocked, while the planet carrier 57 is released. The cover 3 can thus be lowered from the raised position to the closed position.

Switching of the distribution transmission device 20 is performed by using, instead of the slider 99,
This can be done by one or more switching electromagnets that respond manually or automatically. Transmission switching point (
The locking member (for example,
It can be marked by a locking spring) or by a fixed stop. If the mark is made with a fixed stopper, the stopper must be removed when the cover is further driven.

The distribution transmission device 20' provided on the roof in FIGS. 4 to 6 is the same as the distribution transmission device 20 described with reference to FIGS. 7 to 9, except for the manner in which the gear ratio is changed. That is, in the case of a distribution transmission, the planet carrier 67 and the pinion 16 do not or hardly rotate while the cover 27 slides between the positions of FIG. 5.6.

(Example) In the case of the vehicle roof according to the present invention, there is no need to provide a clutch that is prone to failure. The distribution transmission is connected to the roof device by means of a zero distribution transmission which can be installed in a protected location, for example below the fixed roof surface in front of the leading edge of the roof opening, i.e. outside the exposed area of the roof. The optimum speed step can be easily selected for each required adjustment movement. In this case, any primary drive device (e.g. manual crank device, electric motor) can be provided.

According to an embodiment of the invention, the distribution transmission is a planetary gearing, preferably comprising two sun gears arranged coaxially and two groups of planetary gears each rotatably supported on a planetary carrier. A particularly compact and robust construction is obtained if it is constructed as a double-rotary gearing. In this case, it is advantageous to connect both sun gears to the input shaft in a rotation-proof manner, while one output shaft is arranged coaxially to the input shaft and is connected in a rotation-proof manner to the planetary carrier of one planetary gear group. . The planet gears of both planetary gear groups are meshed with the internal tooth row of an external gear, which has an internal tooth row and an external tooth row and is arranged coaxially with the sun gear, and through the external tooth row of the external gear,
Preferably, it is expedient to drive the further output shaft by meshing a toothed wheel, which is connected to the further output shaft in a non-rotating manner, with the external toothing of the external gear. By appropriately selecting the ratio of the number of teeth on each gear, all desired rotational speed ratios can be obtained for both output shafts.

By stopping the external gear or the planetary carrier of the further planetary gear group by means of the switching device, the distribution transmission can be switched in a simple manner.

It is expedient to provide the switching device with a locking device which can selectively engage a locking member of the external gear or of the planet carrier in a predetermined relative rotational position of the external gear and of the planet carrier of the further planet gear group.

Switching of the distribution transmission can be done manually. However, it can also be designed so that the distribution gear changes automatically when a predetermined relative position is reached.

Furthermore, the vehicle roof according to the invention provides that the distribution transmission is automatically switched starting from a predetermined relative position, depending on the selectable drive direction of the input shaft, into the connection position associated with the drive direction in question. It can also be configured as follows.

However, it is also possible to provide a switching device which automatically switches the distribution transmission when a predetermined relative position is reached.

A preferred embodiment of the automatic switching device is defined in claim 1.
It is shown in items 1 to 18.

The cover device may be unitary or multi-segmented; for example, the vehicle roof has a spoiler roof or a unitary cover, the pivoting device of the cover being drive-coupled with one output shaft; The system may be a sliding/tilting roof with a cover sliding device drive-coupled to a separate output shaft.

The actuator can also be used to drive two or more cover parts, for example in the case of a slider roof with a windshield that forms part of the roof surface in the inactive position.

The invention will now be described in detail with reference to embodiments illustrated in the accompanying drawings, in which: FIG.

In the case of the spoiler roof shown in FIGS. 1 to 3, a roof opening 2 is constructed in a fixed roof surface 1. In the spoiler roof shown in FIGS.

In the closed position (FIG. 1) the cover 3 covers the roof opening 2.
Close. In this case, the gasket sealing the gap between the edge of the roof opening 2 and the cover 3 and the known structural details of the vehicle roof are not shown for reasons of clarity.

On both sides of the cover 3, near the rear end of the roof opening 2,
Each is provided with a lifting lever 4.

Only one lifting lever is shown in Figures 1-3.

The lifting lever 4 is pivotable around a receiver 5 that is immovable with respect to the roof surface 1. One end of the lever on the opposite side from the receiver 4 is pivotally connected to the cover 3 by a rotating neck shaft 6. The rotating neck shaft 6 can be displaced within a guide slit 7 of a guide rail 8 provided on the underside of the cover 3 and extending in the longitudinal direction of the cover. On both sides of the cover 3, a cover support member 1 is provided near the front edge of the cover.
Only one cover support member is shown in the 0 drawing where 0 is the attachment. The cover support member 10 is pivotally connected by a joint 11 to a slider 12 which is movable in the longitudinal direction of the vehicle in a stationary guide rail (not shown).

The pivoting movement of the lifting lever 4 around the receiver 5 is carried out by means of a screw cable 13, while for the sliding movement of the slider 12 a screw cable 14 is provided.

On the other side of the cover 3 there is a corresponding screw cable 13',
14' reaches the lift lever and slide. The screw cables 13.13', 14.14' engage a pinion 16.17 (FIG. 7) which is mounted against slippage on the output shaft 18.19 of the distribution transmission 20. The distribution transmission 20 has an input shaft 21 that is drivingly coupled to a primary drive 22 (eg, a hand crank, an electric motor).

When the cover 3 is raised from the closed position shown in FIG. 1 to the position shown in FIG. 2, only the screw cable 13 is displaced and the screw cable 14 is not operated.
The lifting lever 4 is turned clockwise in FIG. 1.2. In order to accurately and reliably control the intermediate position of the cover 3 between the closed position (FIG. 1) and the fully raised position (FIG. 2), the pivoting movement is preferably carried out relatively slowly. Purposeful.

After reaching the position shown in FIG. 2, when the cover 3 is slid backwards (FIG. 3), the distribution gear 20 causes both screw cables 13, 14 (correspondingly screw cables 13', 1
4') is also displaced. The screw cable 14 causes the slider I2 and the cover 3 to slide rearward in the longitudinal direction of the vehicle. At the same time, the lifting lever 4 is
is rotated slowly clockwise. In this case, the angle of rise of the cover 3 is made relatively small, or the cover 3 is pivoted to a position approximately parallel to the fixed roof surface.

4 to 6 show a vehicle roof with a cover consisting of two parts 26, 27. The front cover 26, which can be used as a windshield, is pivoted at its end opposite the cover member 26 to a lifting lever 28 which is drivingly connected to the screw cable 13. Attached to the rear roof part 27 is a groove guide 29 with three holes 30.

A sliding pin 31 of a slider 32, which is displaced in the longitudinal direction of the vehicle by the screw cable 14, runs within the slit 30. Of course, also on the other side of the roof are structural members 28 to 3.
Corresponding structural elements 2 are provided and are drivingly connected to corresponding screw cables 13', 14'.

For ventilation of the passenger compartment, the distribution gear 20' and the screw cable 13 make it possible to raise the front cover part 26 with the rear roof part 27 held in the closed position, as shown in FIG. Starting from the FIG. 5 position of the cover part 26,27, the rear roof part 27 is then lowered in the manner of a conventional sliding roof by means of the distribution gear 20° and the screw cable 14 below the fixed roof surface 1. can be moved to In this case, the cover part 26 is held in the raised position as a windbreak (FIG. 6).

In the case of this embodiment of the vehicle roof, in the first stage (transition from the position of FIG. 4 to the position of FIG. 5) the screw cable 13
(and the corresponding screw cable 13') are only driven displaced. On the other hand, in the subsequent movement phase (transition from FIG. 5 to FIG. 6), essentially only the threaded cable 14.14° is displaced after switching the distribution gear 20′.

The distribution transmission 20, shown in detail in FIGS. 7-9, has a lower housing half 51 and an upper housing half 52. The input shaft 21 is rotatably supported in the lower half portion 51 of the housing. A portion 54 projecting upward from the flange 53 of the inlet kashaff 1-21 is provided with a flat portion (FIG. 9). A cylindrical flange 53 of the input shaft 21 is supported on the bottom surface of the lower housing half 51. A portion 54 of input shaft 21 projecting upwardly from flange 53 has an essentially square cross-section and is positively connected to lower sun gear 55 and upper sun gear 56 . Flange 5

In the planetary carrier 57, the bores 58 for the holding bolts 59 that rotatably support the lower planetary gears 60 are arranged so as to be offset in the radial direction with respect to the axis of the input shaft 21 and uniformly in the circumferential direction. It is distributed and provided. The planetary gear 60 meshes with the sun gear 55 and an internal tooth row 61 of an external gear 62 coaxial with the input shaft 21 and the sun gear 55. The retaining disk 63 secures the sun gear 55 and the planet gear 60 in the axial direction. do.

Correspondingly, the upper sun gear 56 has three upper planetary gears 6
It meshes with 4. These planetary gears are rotatably supported by a holding bolt 65, and at the same time, the internal tooth row 6 of the external gear 62
It meshes with 1. The retaining bolt 65 is attached to the housing upper half 52.
The upper planetary carrier 67 is engaged with a bore 66 of an upper planetary carrier 67 supporting an output shaft 18 rotatably supported on the upper planetary carrier 67 . A retaining disk 68 secures the sun gear 56 and the planet gears 64 in the axial direction. The external gear 62 is inserted into the recess 69.67 of the planetary carrier 56.67. It is rotatably attached to the To. The protrusion 71 of the input shaft 21 is rotatably supported in the central bore 72 of the upper planetary carrier 67 .

The external gear 62 has an external tooth row 74 . This external tooth row has

8.19 is connected to prevent pinions 16.17 from idling. The screw cables 13.13', 14.14' are held in engagement with the pinion 16.17 by cable guides 76, 77, respectively.

The radially projecting peripheral flange 80 of the external gear 62 and the essentially identical peripheral flange 81.82 of the planetary carrier 57.67 are each provided with an axially penetrating slit 83,84,85. . Slit 83.

It is mounted so that it can move in the axial direction. The locking mechanism 88 has two radially projecting noses 89,90. The nose 90 is inserted into the slit 83 of the external gear 62 or the lower planet carrier 5 depending on the axial position of the fixing mechanism 88 in order to stop the rotation of the external gear or the lower planet carrier.

is the provision. The other end of the leaf spring 93 is fixed to a switching knob 95 with a screw 94. This switching knob is loaded downwardly into the position shown in FIG. 8 by a preload spring 96 configured as a coil spring. The switching knob 95 is guided so as to be movable in the axial direction within a bushing 97, which is inserted into a corresponding bore in the lower housing half 51. A slider 99 having a running slope 100 that engages with the lower end of the switching knob 95 is guided by a dovetail guide 98 on the lower surface of the lower housing half 51 .

The function of the above-mentioned distribution transmission device 20 was previously explained in the "Operation" section, and will therefore be omitted here.

The distribution transmission 20'' of FIG. 10 is designed to cooperate with an electric primary drive and includes an automatic switching device generally designated 104 (shown in greater detail in FIGS. 11-14). The distribution transmission device 20 is different from the distribution transmission device 20 described in detail with reference to FIGS. 7 to 9 in that the distribution transmission device 20"
corresponds to the distribution transmission 20 and includes a lower sun gear 55 and an upper sun gear 56 which are connected to the shaft 21 in a non-slip manner.

The lower sun gear 55 is a lower planetary gear 60 rotatably supported by the lower planetary carrier 57 via a support bolt 59.
Upper sun gear 56 , which meshes with upper planet gear 64 , correspondingly engages upper planet gear 64 , which is rotatably journalled on support bolt 65 of upper planet carrier 67 . In the illustrated embodiment, the planetary gears 60 and 64 mesh with the inner tooth row 61 of the external gear 62.
This external gear consists of a toothed ring 105 and a flange ring 106 fixed to this ring. The outer tooth row 74 of the external gear 62 is connected to the output shaft 19 to which the pinion 17 is attached.
It meshes with a spur gear 75 which is coupled to prevent it from idling. The upper planet carrier 67 is connected to the output shaft 8 on which the pinion 16 is mounted.

In the space defined by the housing parts 51, 52, there is further installed a worm gear 107 which is connected to the shaft 21 in a non-slip manner and meshes with a worm shaft 108 which is rotatably supported on the housing part 51. be. Worm shaft 10B is driven by a drive prime mover, preferably an electric motor (not shown).

The switching device 104 includes an external gear 62 and a planetary carrier 5.
7 (Fig. 11.13.14).

External gear 62 and planetary carrier 5 of distribution transmission 20''
The peripheral flanges 80, 81 of 7 are each configured with a locking recess 113, 114. Locking recess 113.11
4, viewed in the circumferential direction, are each formed by an essentially radially extending surface 115 and an inclined surface 116. Correspondingly, the essentially radially slidably mounted locking part i11.112 has an external gear 6.
2 and the end facing towards the lower planet carrier 57, respectively, are configured with an inclined surface 118 complementary to the radially directed outer surface l and the inclined surface 116. (In a predetermined relative position of the performing element, i.e. in a relative position corresponding to the cover position of FIG. , are radially aligned with the locking recesses 113, 114, and are configured to be locked in the locking recesses 113, 114 by preload springs 119, 120.

When moving the cover 3 from the position shown in FIG. 2 to the closed position shown in FIG. 1, the shaft 21 is rotated clockwise (arrow 121) in FIG. 11. The above rotation of the shaft 21 causes the planetary carrier 57 to move clockwise (in FIG. 11).
The external gear 62 is rotated counterclockwise (arrow 123) and the external gear 62 is rotated counterclockwise (
arrow 124). In this case, the inclined surface 118 of the locking par 111 and the locking recess 1 of the planetary carrier 57
14, the locking par 111 resists the force of the preload spring 119 and moves to the locking position (
Figure 11). The planet carrier 57 is released for rotational movement. On the other hand, the radial surface 115 of the locking recess 113 of the external gear 62
abutting the radially facing outer surface 117 of 12; The locking par 112 is fixed at the locking position shown in solid lines in FIG.

The rotational movement of the external gear 62 is prevented.

When the cover 3 reaches the closed position (FIG. 1), the planetary carrier 57, the external gear 62 and the locking pars 111, 11
2 assumes the relative position shown in FIG. Now, when the cover 3 is raised again, that is, in the direction of the position shown in FIG.
When moving, the worm gear 107 and shaft 21 are driven in the opposite direction (arrow 125 in FIG. 13) via the worm shaft 108. Correspondingly, planetary carrier 5
7 and the direction of rotation of the external gear 62 is reversed (arrows 126 and 127 in FIG. 13). In this case, locking par 1
11 releases the planet carrier 57. At the same time, the external gear 62 acts to disengage the locking par against the force of the preload spring 120, since the inclined surface 116 of its locking recess 113 cooperates with the inclined surface 118 of the locking par 112. To prevent this effect, the switching lock device 130
(Fig. 11.12) is provided. The locking device 130 has two locking levers 132, 133 which are pivotable about a common axis 131 and each have a fork-shaped end 134, 135. Each locking par 111
．． 112 D is an arm 136.1 that projects laterally.
37 is fixed, and the nose of the arm 138.13
9 engages in the slit formed by the hawk-like ends 134 and 135. Pin-shaped long members 142, 143, 144, 145 are inserted and fixed in the housing part 140, 141. The ends of the lock members 142 to 145 facing the lock levers 132, 133 are configured in a hemispherical shape. In the locking position of both locking pars 111, 112 (Fig. 11.12), the locking members 142-14
The ends of the locking levers 132, 133 engage in recesses 146, 147° 148, 150 provided on opposite sides of the shaft 131, in which case the locking levers 132, 133 are moved by leaf springs 151, 152. Lock members 142-14
The shaft 131 is centered in the axial direction with respect to the hemispherical end of the shaft 131 .

When the locking par 111 moves from the position shown in FIG. 11 to the position shown in FIG. 13, it is removed from the locking recess 114.

In this case, the locking lever 132 is pivoted counterclockwise around the shaft 131 by the nose 13B of the arm 136. During the above-mentioned pivoting movement of the lock lever 132, the lock lever 132 is lowered by the lock lever 133 in the direction of the shaft 131 against the force of the leaf spring 152 (FIG. 12), so that the lock member 142.14
3 ends are pushed out of the respective recesses 146,147.

In this case, the ends of the locking elements 144, 145 penetrate deeper into the recesses 148, 149 of the locking lever 133. Therefore, when the lock lever 132 is turned from the position shown in FIG. 11, the lock lever 133 is prevented from turning. Therefore, when the external gear 62 attempts to rotate from the position shown in FIG. 13 in the direction of the arrow 127 in the above-described manner described with reference to FIG.
7 to hold the locking par 112 in the locked position.

When shaft 21 is rotated from the cover position of FIG. 2 in the direction of arrow 125 (FIG. 13), planetary carrier 57 and external gear 62 tend to rotate in the directions of arrows 126 and 127, respectively. In this case, the locking par 111 remains locked, while the locking par 112
Slanted surface 118 of locking par 112 and locking recess 114
By cooperating with the inclined surface 116 of the preload spring 120
is pushed out of the locking recess 114 against the force of. In the cover position of FIG. 3, the locking pars 111, 112, planetary gear 60 and external gear 62 reach the relative positions of FIG. 14. When moving the cover 3 from the position shown in FIG. 3 to the position shown in FIG.
Rotate to Figure 4). As a result, planet carrier 57 and external gear 62 tend to rotate in the directions of arrows 123 and 124, respectively. Since the locking par 112 is disengaged, the external gear 62 can rotate freely. As the locking par 112 is disengaged, the arm 137 and the lock lever 133 are moved to the position shown by the broken line in FIG. In this case, lock lever 133 and lock lever 1
32 f) <As seen in FIG. 12, it is raised against the action of the plate spring 151, so that the lock lever 132 cannot be pivoted.

Therefore, the locking lever 133
is held in the locking position shown in FIG. The planet carrier 57 is fixed.

The switching device generally designated 154 in FIGS. 15-17 corresponds in structure and function to the switching device of FIGS. 11-14.
° corresponds to the above-mentioned locking par 111.112,
They cooperate with the planet carrier 57 and the external gear 62, respectively. The locking parts 111', 112', in contrast to the previous embodiment, are guided in guide tracks 155, 156, respectively, extending parallel to each other, and in a relative position corresponding to the cover position in FIG. As shown in FIG.

In this embodiment, the switching locking device 130', which functionally corresponds to the switching locking device 130, essentially consists of a spherical locking member 158, which is dependent on the movement of the locking pars lit' or 112''. The locking member 158 is attached to an opening 159 in an intermediate wall 160 separating guide tracks 155 and 156 to allow movement perpendicular to the direction of movement.
, the locking member 158 projects from the intermediate wall 160 to one side or both sides. In this case, the protruding portion of the locking member 158 is
, 112". The smaller sides of the recesses 161, 162 (both facing the planetary carrier 57 and the external gear 62, respectively)
It is formed by inclined surfaces 163,164. Thus, for example, when the locking part 112' is pulled out of the locking recess 113 starting from the position of FIG. In this case, the locking member 158 penetrates deeper into the recess 161 of the other locking part 111'' (FIG. 16).

Thus, if the locking par 112 is released,
Dissociation of the locking par 111' is prevented. Conversely, if the locking pawl 111' first leaves the locking position, the disengagement of the locking pawl 112° is correspondingly prevented. In this case, the locking member 158 is inserted into the recess 162 and fixes the locking part 112'.
