Abstract

The invention relates to a constant steering control mechanism and method for a radius rod connected trapezoidal swing arm and a multi-wheel vehicle. The radius rod connected trapezoidal swing arm is in a right-angled triangle shape and forms an ellipsograph together with a two-dimensional synthetic control transmission arm of a cross-shaped chute formed by a transverse groove and a vertical groove; the length of the trapezoidal swing arm is R*M / H; along with a steering wheel rotation angle alpha, a radius rod connected trapezoidal swing arm end bearing generates an identical cosine compensation effect, R*cos beta i=R*cos alpha+ / -R*M / H* sin alpha, and the longitudinal cosine displacement is controlled by a sliding block sliding in the transverse groove; a right-angle end bearing is hinged with a connecting rod and then connected with the sliding block sliding in the vertical groove to control transverse sinusoidal displacement, the end bearing on the two-dimensional synthetic control transmission arm, namely a key control point bearing, draws a deflection elliptical track, and the hinged sliding block is connected with a vector control swing arm sliding groove to generate a steering angle beta i; and the electric potential of the electronic control differential speed mark of each wheel driving half shaft is obtained by a sliding resistor or a Hall induction brushless potentiometer arranged at a proper position.

Description

technical field [0001] The invention relates to the technical field of steering of non-rail vehicles, and more specifically relates to a radius rod conjoined trapezoidal swing arm identity steering control mechanism, a method and a multi-wheel vehicle. Background technique [0002] At present, in the steering technology of multi-wheel vehicles at home and abroad, the front wheel steering is mainly based on trapezoidal transmission compensation, but trapezoidal steering is an approximate steering technology. In the mathematical analysis of trapezoidal steering, the steering effect curve is only in the vicinity of 3 degrees and 35 degrees. When the straight line crosses and overlaps, when the angle is greater than 43 degrees, the dispersion increases, causing the tires of the turning vehicle (especially prone to parking) to slip, and even accompanied by steering wheel shaking and abnormal noise. [0003] In order to overcome the above-mentioned defects, the applicant of this c...
