Title:
REAR AXLE STEERING DEVICE FOR AUTOMOBILE HAVING TWO REAR AXLES
Document Type and Number:
Japanese Patent JPS6280162
Kind Code:
A
Abstract:
PURPOSE:To obtain an always constant stability in steering operation irrespective of variations in vehicle speed and variations in the position of a loaded burden, by carrying out steering operation in such a way that front rear and rear rear axles are turned by means of a control means and hydraulic cylinders in order to steer the vehicle. CONSTITUTION:A spool in a change-over valve 38 is displaced by means of an actuator 46 in accordance with a control signal from a microcomputer 47, and therefore, oil pressurized by an oil pump 39 is fed into the front or rear chamber 36 defined by a piston 36 in a hydraulic cylinder 37 so that torque rods 27 are extended and retracted. Of a pair of right and left side torque rods 27, for example, the left side torque rod 27 is made to be longer while the right side torque rod 27 is made to be short to turn rear axles 13 coupled with the torque rods 27 rightward to carry out steering operation of the rear axles. With this arrangement it is possible to obtain an always constant stability in steering operation irrespective of variations in vehicle speed and variations in loaded burden.
