Abstract

See full text

In a vehicle steering device, extendable portions whose elastic properties corresponding to a force acting in a compressing direction and whose elastic properties corresponding to a force acting in a stretching direction are asymmetrical are disposed in a symmetric fashion at intermediate sections of tie rods. Thus, an effective steering gear ratio with respect to leftward and rightward steering can be properly changed in accordance with a vehicle speed by using a simple configuration that does not use a complex mechanism having a motor. In this case, a steering gear ratio can be mainly changed for one of the wheels, while a linear lateral force corresponding to steering can be generated at the other wheel. Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's operational feel.
