| Summary: | The paper deals with linkages used to actuate the retractable top of convertible
passenger car, which are either a simple articulated 4-bar mechanism or a stacking multi-contour
n-bar mechanism. The car top that can fold or unfold is consisting of two or three hard
components. The folding linkage of the hard top is a planar kinematic chain with articulated bars
which allows the two or three top parts to be stacked into the trunk room. To be observed that the
first hard component of the kinematic chain is the car rear screen and the second hard part is
actually the retractable top. In order to fold the car top and the rear screen, the door trunk is
actuated by means of a simple hinge pair or a 4-bar mechanism. In the case of a larger passenger
car, the top consists of two parts and together with the rear screen form the open kinematic chain
which can be closed by means of some stacked kinematic chains. Using CAD modeling and
kinematic simulation of the retractable textile car top linkage used on convertibles, the mechanism
efficiency regarding its operation can be improved. Through Inventor®
software the user can
modify any part or subassembly of the mechanism at any moment. This can be done by means of
the parametric design which allows that any changing on a component to be instantaneous
reflected on the assembly which that part belongs to. |
