PURPOSE:To provide active controllability for front and rear wheels while the front/rear controlled balance is maintained good by furnishing a same-phase steering means to steer the rear wheels in the same direction as the front, an opposite-phase steering means to be actuated when the steering is started, and a phase advance steering means for cut-increasing the steering angle of the front wheels. CONSTITUTION:A power steering 6 is formed in combination of a steering gear assembly 9 with a power cylinder device 10 and an oil pump 13, which supplies oil pressure to a rotary valve 7. Therein a steering wheel 17 is coupled with the input shaft 7a of the rotary valve 7 and a torsion bar 8 through a phase advance steering means 14 and a column shaft 16. A two-gang rear power cylinder 90 is installed in such an arrangement as to couple a left and a right pivoting shaft 89, 89 of the rear-wheel suspension, and the left and right chambers 97a, 97b of this rear power cylinder are connected to a control valve 98 for the same phase, and the two cylinder chambers 92a, 92b are connected with another control valve 100 for opposite phase, which shall be controlled interlocked with the phase advance steering means 14. |
