Abstract
The present invention relates to a vehicle steering mechanism having a variable transmission ratio, and a steering gear designed for such a steering mechanism.
Claims22
Vehicle steering mechanism with a variable transmission ratio, having a steering gear (10;
- 110;
- 210;
- 310) comprised of a drive component (20;
- 120;
- 220;
- 320) which rotates around a first rotational axis (50;
- 150;
- 250;
- 350) and which is coupled via a connecting component (30;
- 130;
- 230;
- 330) to an output component (40;
- 140;
- 240;
- 340) which rotates around a second rotational axis (52;
- 152;
- 252;
- 352), wherein the drive component (20;
- 120;
- 220;
- 320) is connected to the connecting component (30;
- 130;
- 230;
- 330) such that the drive component can pivot around a third rotational axis (54;
- 154;
- 254;
- 354), and the connecting component is connected to the output component (40;
- 140;
- 240;
- 340) such that the connecting component can pivot around a fourth rotational axis (56;
- 156;
- 256;
- 356), characterized by a positioning of the four rotational axes such that the four rotational axes intersect at a single point, and the minimum angle (ν) formed between the first rotational axis (50;
- 150;
- 250;
- 350) and the fourth rotational axis (56;
- 156;
- 256;
- 356) ranges from 0.1 degree to 40 degrees.
36 more elements
A steering gear having a variable transmission ratio, comprising:
- a driving component rotatable about a first axis;
- a connecting component rotatable about a fourth axis, said driving component being pivotably connected to said connecting component about a third axis generally orthogonal to said first axis;
- and
- an output component rotatable about a second axis, said connecting component being rotatably mounted on said output component about said fourth axis,
- wherein said first axis and said fourth axis are skewed relative to each other.
