Definitions

  • the invention relates to a transmission for converting a rotary movement into a positively guided linear back and forth movement perpendicular to the axis of rotation, in particular for locking and unlocking a steering lock of a motor vehicle, with a displaceably mounted guide link with an elongated opening, in which a rotor with side wings is arranged, the wings rest on guide surfaces of the backdrop.
  • both parts In order to avoid breakage of the link or rotor, both parts must have certain minimum dimensions, which means a high weight and a considerable amount of material. This contradicts the goal of lightweight construction in automotive technology.
  • the invention is therefore based on the object of designing the transmission of the type mentioned in such a way that parts of smaller dimensions and more compact construction are used for the transmission and the guide link is positively guided in both directions.
  • the rotor has, in addition to the vanes, a cam arranged in the center thereof, to which at least one guide surface of the link is also assigned, at least one of the vanes and the cam always abutting or being close to their guide surfaces.
  • Such a transmission enables the guide link to be guided in both directions.
  • the cam and the wing are arranged near the axis of rotation on the rotor, so that large forces can be transmitted and transmitted to the guide link in both directions by the wing and the cam.
  • the gearbox according to the invention has a high level of safety and high in a simple and compact design Lifetime and avoids the disadvantages described in the transmissions used today.
  • the guide surface of the link provided for the cam is tooth-shaped.
  • the guide surfaces provided for the cams can also be curved and abut at an obtuse angle. It is also advantageous if the guide surfaces provided for the cams are curved concavely.
  • the cam is tooth-shaped.
  • the tooth-shaped embodiment of the cam and the corresponding guide surfaces enables good power transmission from the cam to the guide surfaces at different angles of rotation.
  • Another preferred embodiment of the transmission according to the invention is that the wings and the cam are integrally connected to the rotor.
  • the two guide surfaces provided for the wings are arranged on the guide link at approximately the same height from one another, approximately at the width of the wings below the axis of rotation.
  • the transmission has a receiving body 1, which receives a socket 2.
  • a guide link 3 is slidably mounted transversely to the axis of rotation C of a rotor 5.
  • the rotor 5 lies with its axis of rotation coaxial to the cylinder core of the steering lock of a motor vehicle and is fastened, in particular coupled, to the inner end of the cylinder core.
  • the guide link 3 has an elongated opening 4 in which the rotor 5 can be rotated back and forth about the axis of rotation C.
  • the rotor 5 has two laterally molded wings 6 and a tooth-shaped cam 8 molded in the center of these wings. In the center of the rotor 5 there is an opening 7 into which the lock can be inserted. Blade 6, cam 8 and rotor 5 are solid and integrally connected.
  • the elongated opening 4 of the link 3 is delimited in sections by projections 9 and 10 with guide surfaces 11 and 12, which are each assigned to the cam 8 or one of the wings 6.
  • the two guide surfaces 11 for the cam 8 are slightly concavely curved, abut each other at an obtuse angle and form a tooth 13 directed against the cam 8.
  • one of the guide surfaces 12 provided for the two wings 6 is located on one side of the backdrop 3 to each other in approximately the same height, approximately at the blade width spacing B below the axis of rotation C of the rotor 5.
  • the cam 8 moves along the guide surface 11 and presses on the guide surface 12 of the link 3, so that the link 3 executes a linear movement in the direction of rotation . If, on the other hand, the rotor 5 is moved back into the freewheeling position, the cam 8 slides again on the guide surface 11 and moves the link 3 again linearly in the direction of rotation of the rotor 5. Depending on the direction of rotation of the rotor 5, the rotary movement becomes a linear reciprocating movement Backdrop 3 implemented so that the steering lock can be locked or unlocked.
