Definitions

  • the invention relates to a transmission device for Transmission of electrical signals between a rotor and a stator, with one of the rotor and the stator formed annular space, the Gap several between the rotor and the stator running, can be wound up and unwound in the space Includes ribbon cable.
  • Such a transmission device can, for example are used in the steering column area of a vehicle, then the rotor is arranged on the steering wheel side and the Stator on the body side. In modern vehicles a number of functions via switches on the steering wheel actuated. About a related to the invention Transmission device can through the switch triggered, electrical signals body side, the Rotational movement of the steering wheel not following consumers or Control units are fed.
  • the ribbon cable in Space to be redirected. Because of the redirection it is possible to shorten the length of the flat cable, and nevertheless a sufficiently high number of revolutions of the rotor enable.
  • the ribbon cable consists of regularly a plurality of arranged parallel to each other Ladders using basic insulation are summarized.
  • the present invention is therefore based on the object to provide a transmission device that has a simple structure and is still durable reliable winding and unwinding of several Ribbon cables between the rotor and the stator enable.
  • This object is achieved in that Gap several, independently movable arranged support body are provided, each Support body for supporting a ribbon cable.
  • Support bodies for the various ribbon cables can with not exactly identical winding behavior of the Ribbon cable and if the length of the cable is not exactly identical single ribbon cable for clamping the support body come in the space.
  • each support body advantageously has a groove-like receptacle for the respective ribbon cable on, with the ribbon cable in the respective receptacle are carried out in such a way that winding and unwinding is possible is.
  • the groove-like receptacles are preferably in between Top view curved such that the Ribbon cable largely during winding and unwinding be carried out continuously and without kinks.
  • the guide means can in particular guide grooves, Include guide bars, guide rails or the like.
  • the supports advantageously in the respective direction of movement extending supernatants. This avoids that the supporting bodies hinder each other by closing get close to the neighboring support body.
  • the number of support bodies advantageously corresponds the number of ribbon cables.
  • the adjacent support body one have the same possible distance from each other.
  • four ribbon cables should be provided the distance between the respective center of the support body approx 90 ° in relation to the axis of rotation of the rotor.
  • spring elements are provided between the individual support bodies, each of which applies a small spring tension to two adjacent support bodies. This advantageously ensures that play between the support bodies is eliminated, thereby avoiding annoying rattling noises. It is also conceivable according to the invention that spring elements are provided on the support bodies, which support the respective support body against the rotor and / or the stator. This also prevents annoying rattling noises.
  • the spring elements come in particular at the respective Support body arranged spring tongues into consideration.
  • Spring tongues can be provided, which are located on the respective support the adjacent support body.
  • you can Spring tongues are provided, which the support element against the Support the rotor and / or the stator.
  • a particularly preferred device is characterized by this from that the ribbon cable and the axis of rotation on the radially inside and on the radially outside partially wound up inside of the space are arranged and above the respectively associated Support body from one inside to the other inside be redirected. This ensures that a correct and kink-free winding or unwinding the respective ribbon cable on the inside of the space.
  • Guide the support body advantageously the ribbon cable over the almost entire area from one inside to the other.
  • Figures 1 and 2 show an inventive Transmission device 10, the one rotor 12 and one Stator 14 includes. Between the rotor 12 and the stator 14 are a total of four ribbon cables 16, 18, 20, 22 provided the electrical signals between the rotor 12 and transmitted to the stator 14.
  • the rotor 12 serves in particular for connection to a steering wheel of a vehicle.
  • the stator 14 is used in particular to connect to a Steering column module of the vehicle.
  • About the Transmission device 10 can consequently be electrical Signals from the steering wheel, not shown, to not Steering column switch shown, not shown Actuators or to a not shown Control unit are performed.
  • the ribbon cables are in one of the rotor 12 and the stator 14 formed space 24 housed. She are arranged so that they are about the axis of rotation 26 on the radially inner side 28 of the Intermediate space 24 and on the radially outer Inside 30 are arranged partially wound. Of one inside 28 to the other inside 30 the four ribbon cables each via a support body 32, 34, 36, 38 deflected.
  • the support body are here Gap 24 is freely movable independently of one another the circular path 40 is arranged around the axis 26.
  • each support body has a groove-like receptacle 42, in of the respective ribbon cable.
  • the Recordings 42 are shown in FIG Top view curved such that an opening and Unwinding the respective ribbon cable is possible.
  • each Recording 42 is largely parallel to one another by two running guide walls 44 and 46 limited.
  • the individual support bodies also see themselves in one Overhangs 56 extending in the direction of movement (arrow 50) in front, by keeping a safe distance from neighboring ones Support bodies is given. So that the support body not be moved as close to each other as desired.
  • spring elements shown may be provided, each two adjacent supporting bodies with a small one Apply spring tension. This allows a game in Direction of movement of the support body are eliminated, whereby Rattling noises of the transmission device 10 prevented become.
  • spring elements, not shown, can be provided, the respective support body against the Support rotor 12 and / or stator 14. This can any existing game is also excluded become; this also prevents rattling noises.
  • the individual spring elements can in particular directly be molded onto the individual support body.
