A GEOMETRIC METHOD FOR OPTIMIZE THE ACKERMANN-TYPE STEERING MECHANISM

Nicolae URSU-FISCHER, Diana Ioana POPESCU

Abstract


The Ackermann’s four-bars linkage, having the shape of an isosceles trapezoid, is used in the steering mechanism of the cars, making rotations with unequal angles of the front wheels, in order to eliminate the slip frictions during changing the vehicle direction of travel.

Both Ackermann's mechanism and other mechanism which perform similar tasks have come to the attention of many researchers over time and there it is a lot of scientific work in this field.

One of the important tasks is the dimensional optimization of the mechanism, to ensure compliance with a certain relationship between the angles of rotation of the two front wheels, around some axes perpendicular on the ground.

 The authors propose a new method of optimization, based on geometric aspects. Theoretical problems are presented as well as a numerical example that fully justifies this new optimization methodology and its correctness.
