Description

Folding top for a motor vehicle The present invention relates to a folding top for a motor vehicle, having two main bearings which are fixed to a vehicle body and in which a roof linkage, which bears individual roof sections of the top, is mounted so as to be pivotable between a closed roof position and a stowed roof position, wherein the roof linkage has a tensioning hoop for tensioning the folding in top in its closed position, wherein the tensioning hoop can, on each of the two sides of the motor vehicle, be transferred into its tensioning position by way of a knee lever, and the knee lever can be actuated by way of a hydraulic cylinder.
is A folding top of said type is known from DE 10 2006 042 296 Al. In said document, for the actuation of the tensioning hoop on a top link arranged in each case on the top on each side of the vehicle, a tensioning bar is provided which serves as a so-called storm bar and which is formed from two link levers connected articulatedly to one another. Said link levers are formed as knee levers and are situated, so as to run in extended fashion relative to one another, in a beyond-deadcenter position, out of which they can be moved only by way of corresponding external forces exerted on the joint or on one 2s of the link levers. For this purpose, there is provided between the two link levers a hydraulic cylinder by means of which the link levers can be moved out of or into the beyonddead-center position.
The present invention seeks to further develop a folding top of the type mentioned in the introduction such that, in particular with an optimum transmission ratio of the knee lever, in particular during the transfer thereof into a closed position of the tensioning hoop, a large amount of freedom with regard to the positioning of the knee lever and of the hydraulic cylinder is ensured.
An aspect of the invention provides a folding top in accordance with the features of patent claim 1.
In the case of the folding top according to the invention, it is thus provided that the knee lever and the hydraulic lc cylinder are mounted, on the respective side of the vehicle, in a main bearing of the folding top.
Said main bearing performs the function of connecting the Z-shaped kinematic arrangement of the folding top to the vehicle is body. In general, said main bearing may also be referred to as top bearing.
The mounting of knee lever and hydraulic cylinder in the main bearing makes it possible, owing to the mounting in the same bearing part, to realize considerably greater freedom with regard to the positioning of the knee lever and of the hydraulic cylinder. This is associated with considerable packaging advantages. Said arrangement of the knee lever makes it possible to realize an expedient transmission ratio of the 2s forces exerted by the knee lever when the tensioning hoop is closed and furthermore also when the tensioning hoop is deployed. This is particularly advantageous from the aspect of the force level and sensitivity to tolerances.
33 A further advantage of the arrangement according to the invention of knee lever and hydraulic cylinder in the main bearing can be seen in increased anti-theft protection, and thus improved security.
It is considered to be particularly advantageous if the knee lever has two lever sections which are pivotably connected to one another, wherein a first lever section is mounted pivotably in the main bearing and a second lever section is mounted pivotably in a tensioning bar which serves for the acLuaLion of Lhe Lensioning hoop, wherein Lhe hydraulic cylinder is pivotably mounted, in the region of its end averted from the main bearing, in the first lever section.
13 This configuration gives rise to an optimum point of engagement of the hydraulic cylinder on the knee lever, specifically in the region of the first lever section, which is positioned closer to the main bearing.
is Said tensioning bar is also referred to as storm bar. Said tensioning bar is intended to ensure, at maximum speeds of the motor vehicle, that the associated tensioning hoop remains in its position, in which it tensions the folding top, when the folding top is closed. Tensioning bars or storm bars are often not in the form of rectilinear bars but are slightly curved. Taking this situation into consideration, the arrangement of the knee lever and of the hydraulic cylinder in the main bearing gives rise to additional support of the tensioning bar or storm bar in the Y direction, whereby the stiffness of the 2s folding top is increased in said region.
The hydraulic cylinder is preferably connected, adjacent to the pivotable connection of the two lever sections of the knee lever, to the first lever section of the knee lever. This 33 gives rise, with regard to the point of engagement of the hydraulic cylinder on the knee lever, specifically on the first lever section, to a very large lever arm with respect to the axis of rotation, which is fixed with respect to the vehicle body, of the first lever section, whereby only relatively low forces are required in order to be able to introduce the same torque into said lever section. In this respect, the knee lever can be dimensioned to be smaller, such that structural space and weight can be saved.
The hydraulic cylinder has a cylinder secLiori and a pisLori rod, wherein preferably, the cylinder section is mounted in the main bearing, and the piston rod is mounted in the knee is lever. Accordingly, the relatively large mass of the hydraulic cylinder is mounted in the main bearing, and the relatively small mass of the hydraulic cylinder is mounted in the knee lever.
is It is preferable for the tensioning bar for the actuation of the tensioning hoop to also be in the form of a knee lever. It is preferably provided that a lever section of the knee lever of the tensioning bar, in particular a front lever section of the tensioning bar, pivotably has the knee lever which serves for the mounting of the hydraulic cylinder. With optimum force transmission of the forces introduced by way of the hydraulic cylinder, it is thus possible for the arrangement of the roof linkage in the region of the knee lever, which serves for the mounting of the hydraulic cylinder, and of the tensioning bar 2s to be configured in a structurally advantageous manner, in particular from the aspect of the required structural space.
It is preferably the case that, in the closed position of the folding top, the tensioning bar and the knee lever which holds 30 the hydraulic cylinder are situated in their beyond-deadcenter position.
Further features of the invention will emerge from the subclaims, from the appended drawing and from the description of the exemplary embodiment depicted in the drawing, without the invention being restricted thereto. In the drawings: figure 1 shows a schematic side view of a section of a folding Lop according Lc Lhe invenLicn in Lhe rear-end region of the motor vehicle, in the closed state of the top, 13 figure 2 shows a three-dimensional view of a sub-region of the section illustrated in figure 1, thus illustrated for the closed position of the top, figure 3 shows the arrangement as per figure 2, illustrated for a partially opened position of the top, is figure 4 shows an arrangement as per figures 2 and 3, illustrated for the folding top arranged in a stowage compartment, and thus open.
Figure 1 shows, in a schematic side view, the folding top 1 according to the invention for a motor vehicle, which is a passenger motor vehicle. The folding top 1 has two main bearings 2 which are fixed with respect to the vehicle body and which are arranged at both sides of the motor vehicle and in which a roof linkage 4, which bears individual roof 2s sections 3 of the folding top 1, is mounted so as to be pivotable between a closed roof position (as illustrated in figures 1 and 2) and a stowed roof position (as illustrated in figure 4). In the embodiment according to the invention, the folding top 1 is designed such that a flexible top material is stretched over the roof linkage 4 in a known manner, which top material is not illustrated for reasons of clarity.
The roof linkage 4 provided on each of the two sides of the motor vehicle has a tensioning hoop 5 for tensioning the folding top 1 in its closed position. The tensioning hoop, wherein only the tensioning hoop 5 situated on the left-hand side of the vehicle is shown in figures 1 and 2, can be transferred into its tensioning position by way of a knee lever. 6. Here, Lhe knee lever 6 can be acLuaLed by way of a hydraulic cylinder 7. Both the knee lever 6 and the hydraulic cylinder 7 are mounted in the main bearing 2 assigned thereto, is and thus, in the illustration of figures 1 and 2, in the left-hand main bearing 2. A corresponding situation applies for the mounting of the other knee lever and of the other hydraulic cylinder in the right-hand main bearing.
ls The knee lever 6 has two lever sections 8, 9 which are pivotably connected to one another. A first lever section 8 is mounted pivotably in the main bearing 2 in the region of a pivotable connection 20, and a second lever section 9 is mounted pivotably in a tensioning bar 10 which serves for the actuation of the tensioning hoop 5 and which is also referred to as a storm bar.
The hydraulic cylinder 7 has a cylinder section 11 and a piston rod 12. The cylinder section 11 is mounted pivotably in 2s the main bearing 2. The piston rod 12 is mounted pivotably in the lever section 8, specifically adjacent to the pivotable connection 13 of the two lever sections 8, 9.
The tensioning bar 10 is also in the form of a knee lever. One lever section 14 of the knee lever of the tensioning bar 10, specifically a front lever section 14, holds the lever section 9 of the knee lever 6, in the region of its end averted from the pivotable connection 13, in the region of a pivotable connection 15. The lever section 14 is connected to a lever section 16 of the tensioning bar 10 in the region of a pivotable connection 17. That end of the lever section 16 which is averted from the pivotable connection 17 is connected, in the region of a pivotable connection 18, to the tensioning hoop 5, approximately in the middle of the length of Lhe Lens lolling hoop 5. AL Lhe frau L Lhe Lens _Luning hoop 5 is pivotably mounted in the region of a further pivotable connection 19. The two lever sections 14 and 16 thus form the 13 knee lever, wherein the knee lever 6 engages, in the region of the pivotable connection 15 at the end which projects are rearward beyond the pivotable connection 17, on the lever section 14 of the tensioning bar 10.
is A part of the forces or of the moments for moving the tensioning hoop 5 are introduced into the latter, via the tensioning bars 10 arranged at both sides of the vehicle, by way of positioning means which are independent of the hydraulic cylinders 7. Said forces or moments are superposed by the hydraulic cylinders 7 arranged at both sides of the vehicle, which hydraulic cylinders introduce forces and moments into the associated knee levers 6, wherein the knee levers 6 interact with the tensioning bars 10.
2s From the illustration of figures 1 and 2, which relate to the closed top position, it can be seen that both the knee lever 6 arranged on the respective side and also the knee lever of the tensioning bar 10 are situated in a beyond-dead-center position. This is reached when the piston rod 12 is fully 33 deployed. During the retraction of the piston rod 12, the knee lever 6 is moved out of the beyond-dead-center position and, in the process, via the lever section 14, also pulls the knee lever pertaining to the tensioning bar 10 out of the beyonddead-center position.
Figure 3 shows the roof linkage 4 in a position which 5 corresponds to the partially open position of the top.
Figure 4 shows Lhe roof linkage 4 in a position which corresponds to the open position of the top, and thus the position in which the top is situated in a stowage is compartment, in particular in a stowed position in a top compartment. Both when the top is closed and when the top is stowed, said top compartment is situated in a position which closes the top compartment. When the top is closec, the tensioning hoop 5 is, by way of the two knee levers 6, braced ls against the top compartment cover and fixed in the beyonddead-center position of the knee levers 6.
