Definitions

  • This invention relates to a kinematic chain for window winders, particularly studied for window winders which are composed of a single drive, usually a drum.
  • two guides which are usually parallel and two supports to which the vehicle window pane is connected.
  • the drive transmits the driving torque to the assembly or unit by means of two cables, which close a kinematic system common to both window pane supports.
  • the cable withstands the tension resulting from the stresses exerted by both window pane supports and, moreover, the dissipative friction forces due to the contact of the cables with the elements arranged at the ends of the guides, such as clips, pulleys or similar items, which allow the angle of the cable to change.
  • each item especially the ends of one of the guides when being raised and those of the other guide when being lowered, are submitted to high levels of friction, which contribute towards increasing the tension that the cables have to withstand and, in fact, increase the drive torque needed to guarantee good operation.
  • the invention claims a kinematic chain whose purpose is to reduce the stress that the cables are subjected to.
  • a second object of the invention lies in achieving a reduction in the levels of friction of the cables on the angle change elements.
  • a third and final objective is the reduction of the drive torque needed in order to achieve efficient operating of the system.
  • the invention claims a kinematic chain for window winders whose drive is composed of two drums on which two cables are wound, respectively. Some of these cables are directed towards the upper and lower ends of one of the guides, while the others do the same in relation to the other guide of the window winder.
  • the two kinematic systems A. and B. are connected to each other by means of two coaxial drums of the same diameter, or, in the case of using two independent drums, through some other torque transmission system, gearing or similar.
  • the two drums required by the invention can be connected by means of a coaxial axis or by means of some other transmission element.
  • drums are not coaxial, they are connected kinematically by a torque transmission element, gearing or similar system.
  • a construction variant of the invention uses different diameters in each of the drive half-drums or drums, in order to achieve different speeds in the two window pane supports of each of the two guides.
  • This variant is particularly applicable in window panes that need complex displacement movements, such as, for instance, the rear windows of convertible cars or in doors which have items inside the door cavity that do not allow the use of traditional systems.
  • a kinematic chain is also claimed for window winders whose drive is composed of two independent drums, on which are wound, respectively, one cable that connects the upper end of one of the guides with the lower end of the other parallel guide.
  • the drive torque is transmitted to the system by means of two coaxial drums of the same diameter, for instance, or by means of a coaxial axis or shaft in the case of two independent drums.
  • drums which are not coaxial in which case the torque transmission system used can be a gear train or similar.
  • each cable is directed towards the upper end of one of the guides and towards the lower end of the other guide, with the particularity that the cables which are under more tension during the raising operation are those that run from the drive unit to the upper ends of the two guides, and during the lowering operation, the two that run from the drive unit to the lower ends of the two guides, which withstand only the load transmitted by one of the window pane supports on board each guide, thus reducing the tension or stress to half in relation to the conventional technique mentioned previously.
  • the two drums of the invention can be joined to each other by means of a coaxial axis or shaft or by means of some other transmission element.
  • the drive can consist of two drums which are not coaxial, kinematically connected by a torque transmission element, gearing or similar.
  • these drums can be directly connected to each other by means of a toothed transmission system incorporated into the drums themselves.
  • the drive unit transmits the drive torque to the unit by means of two cables (4, 5), that close the kinematic system, which, as can be observed, is common to both window pane supports (7,8).
  • the cable (4) In the raising process, the cable (4) withstands the tension resulting from the stresses exerted by the supports (7, 8), plus the dissipative friction forces due to the items (9, 10, 11, 12). As the friction on these latter items, in terms of the tension of the cable on them, each item, particularly those indicated with the positions (23, 26) (9, 12) have high friction levels, which contribute towards increasing the tension that the cable (4) has to withstand and, in short, the drive torque (2) needed in order to guarantee the correct operation of the system.
  • the drive unit is composed of two drums (16, 16'): the cables (18, 20) are connected to one drum or half-drum, while the cable (17, 19) are connected to the other.
  • the drive unit is composed of two drums (31G, 31H) which are not coaxial and are connected by a torque transmission element (44), gearing or similar.
