Drive wheel arrangement for two pivot components of a top of a convertible vehicle
A top of a convertible motor vehicle includes a linkage movable between a closed position spanning a vehicle interior and a storage position uncovering the vehicle interior to the top A linkage arrangement having first and second pivot components is on opposing sides of the linkage and pivotably mounted at a rear main bearing. A rotatable drive wheel is coupled to the two pivot components. When the drive wheel is rotated, the first pivot component is always subjected to a drive torque, whereas the second pivot component, as a function of the position of a control element in a control slot that is fixed relative to the main bearing, is either held in place or is subjected to a drive torque.
1. A top of a convertible vehicle, said top comprising:
a linkage movable between a closed position spanning a vehicle interior and a storage position uncovering the vehicle interior to the top and which, in relation to a vertical longitudinal center plane of the top has opposing sides;
a linkage arrangement on said sides of the linkage and pivotably mounted at a rear main bearing, said linkage arrangement including a first pivot component and a second pivot component;
a rotatable drive wheel coupled to the pivot components, wherein, when the drive wheel is rotated, the first pivot component is always subjected to a drive torque, and the second pivot component, as a function of the position of a control element in a control slot that is fixed relative to the main bearing, is either held in place or is subjected to a drive torque, wherein the control element is a control link pivotably connected to a coupling link having a pivot axis coaxial with an axis of rotation of the drive wheel.
2. The top of a convertible vehicle according to claim 1 , wherein the control link is connected to the drive wheel via a drive link.
3. The top of a convertible vehicle according to claim 2 , wherein the control link includes a first leg and a second leg, the control element being disposed at a free end of the first leg, and the drive link is linked to the second leg.
4. The top of a convertible vehicle according to claim 3 , wherein the first and second legs of the control link span an acute angle.
5. The top of a convertible vehicle according to claim 2 , wherein the control slot includes a first slot portion that runs concentrically to a periphery of the drive wheel and a second slot portion that has an opposite-direction curved profile with respect to the first slot portion, such that when the control element is arranged in the first slot portion, the drive torque is introduced into the second pivot component from the drive wheel via the drive link, the control link and the coupling link, and, when the control element is arranged in the second slot portion, the second pivot component is stopped when the drive wheel is driven.
6. The top of a convertible vehicle according to claim 1 , wherein the drive wheel is a gear wheel, the first pivot component being linked to a side of the gear wheel that faces the vertical longitudinal center plane of the top and the second pivot component being coupled to a side of the gear wheel that faces away from the vertical longitudinal center plane of the top.
7. The top of a convertible vehicle according to claim 6 , wherein the first pivot component is linked via a reduction gearing formed from a link arrangement.
8. The top of a convertible vehicle according to claim 1 , wherein the first pivot component is a rear tensioning bracket of a foldable top, which bracket is connected to a tensioning rod arrangement to which the drive wheel is linked.
9. The top of a convertible vehicle according to claim 1 , wherein the second pivot component is a main link of the respective linkage arrangement, the main link being pivotably mounted at the main bearing.
10. The top of a convertible vehicle according to claim 1 , including a drive motor driving the driving wheel.
11. A top of a convertible vehicle, said top comprising:
a linkage movable between a closed position spanning a vehicle interior and a storage position uncovering the vehicle interior to the top and which, in relation to a vertical longitudinal center plane of the top has opposing sides;
a linkage arrangement on said sides of the linkage and pivotably mounted at a rear main bearing, said linkage arrangement including a first pivot component and a second pivot component;
rotatable drive wheel coupled to the pivot components, wherein, when the drive wheel is rotated, the first pivot component is always subjected to a drive torque, and the second pivot component, as a function of the position of a control element in a control slot that is fixed relative to the main bearing, is either held in place or is subjected to a drive torque, wherein, when displacing the linkage from the closed position into the storage position and when displacing the linkage from the storage position into the closed position, in each case, the drive wheel is driven only in one direction of rotation.
