Definitions

  • the invention relates to a spline, in particular for a drive train of a motor vehicle with two arranged around a rotational axis components with a circumferentially biased rotational closure with each other forming first and second toothing regions, wherein the first toothed region is formed of two toothed elements with circumferentially phase-shifted first and second teeth, the Gear elements by means of an elastomeric body are connected to each other limited rotatably and the first and second teeth are added to form a circumferentially effective biasing force of the elastomeric body on a third toothing of the second toothing region.

  • the first and second teeth are in phase rotated against the action of the modulus of elasticity and pushed onto the third teeth of the shaft, so that the two teeth of the first toothed area braced against the teeth of the second toothed area and thus avoid gearing rattling.
  • the object of the invention is the development of a generic spline.

For example, 15 to 25, preferably between 20 and 24 teeth may be provided on the first toothing, which engage distributed over the circumference in corresponding tooth gaps of the third toothing rotationally.
