PURPOSE:To steer rear wheel immediately after vehicle's commencement of turning motion by organizing improvement on delaying reaction of the said rear wheel against the front wheel with soonest reaction of the former in making turning motion thus obtaining prescribed turning action done easily and in short time. CONSTITUTION:With a vehicle of a pair of wheels on both front and rear, the left side rear wheel 4 (similary with right side rear wheel) is fixed to a quakeable material quakeably set by beng connected to the chassis 1 via shaft 2. The shaft 2 correspnds to the king-pin of the connonly known front wheel steering construction and the quakeable material 3 functions similarly to the knuckle arm. The shaft 2 is set with a formward inclined posture and the extention line 5 of the shaft 2 is designed to cross with the rear wheel direction line D-D on the road surface 6 at the point P. The earth contacting central point A of the rear wheel tire 4 is to come directly under the rear wheel turning centre 4, and the dynamical centre B of the stress which arises on rear wheel 4 at time of turning is made ot come on the point behind the above A, and the ground intersection point P of the shaft extention line 5 is to come further behind the point B. |
