Abstract
A driving device for a convertible top includes a main bearing having a first fixed bearing point, a first link pivotally connected to the main bearing at the first fixed bearing point, a driving cylinder, a push and pull rod, a first bent link, and a second bent link. The first link includes a double lever having two hinge points each positioned on different sides with respect to the first fixed bearing point. The push and pull rod is coupled to one of the two hinge points via the first bent link and coupled to the other of the two hinge points via the second bent link. The driving cylinder provides a force acting upon the push and pull rod.
Claims10
A driving device for a convertible top, comprising
- a main bearing having a first fixed bearing point;
- a first link, said first link being pivotally connected to said main bearing at the first fixed bearing point;
- a driving cylinder;
- a push and pull rod;
- a first bent link;
- and
- a second bent link;
- wherein the first link includes a double lever having two hinge points, said two hinge points each being positioned on different sides with respect to said first fixed bearing point;
- wherein said push and pull rod is coupled to one of said two hinge points via said first bent link;
- wherein said push and pull rod is coupled to the other of said two hinge points via said second bent link;
- and
- wherein the driving cylinder provides a force acting upon said push and pull rod.
A driving device for a convertible top, comprising
- a main bearing;
- a cross joint including a first link, a push and pull rod, and at least two further links, said first link being pivotally connected to said main bearing in a first fixed bearing point;
- and
- a driving cylinder for producing a driving force, the driving force producing a torque about said first fixed bearing point, the driving force acting on said cross joint so as to define an effective lever arm distance of the cross joint;
- and
- wherein the torque at a beginning and at an end of an opening movement of the convertible top is larger than the torque at an intermediate position between the beginning and the end of the opening movement as a result of a larger size in the effective lever arm distance.
A driving device for a convertible top, comprising
- a main bearing;
- a first link being pivotally connected to said main bearing in a bearing point of said main bearing:
- a driving cylinder;
- a push and pull rod, the driving cylinder providing a force acting upon said push and pull rod;
- a first cross-joint link;
- and
- a second cross-joint link;
- the first link including a double lever having two hinge points, said two hinge points each being positioned on different sides with respect to said fixed bearing point;
- wherein said push and pull rod is coupled to one of said two hinge points via said first cross-joint link;
- wherein said push and pull rod is coupled to another of said two hinge points via said second cross-joint link, such that at a beginning of an opening movement of the convertible top torque is exerted about said first fixed bearing point onto said first link by one of said first cross-joint link and said second cross-joint link and at a beginning of a closing movement of the convertible top torque is exerted about said first fixed bearing point onto said first link by the other of said first cross-joint link and said second cross-joint link.
