摘要： A power steering device for a vehicle comprises a steering wheel, a steering linkage operatively connecting the steering wheel to dirigible wheels of the vehicle and a power assisting device inserted into the steering linkage to assist the steering force of the steering wheel. A steering shaft of the steering linkage rotated with the steering wheel to transmit the steering force from the steering wheel to the power assisting device is divided into first and second parts. A pair of coil springs are inserted between the first and second parts of the steering shaft to connect them with each other and is adapted to be elastically deformed to produce a rotational displacement between them when the steering wheel is rotated. A set load is placed on the coil spring so that the coil spring can be elastically deformed only when the steering force from the steering wheel exceeds a predetermined value.

摘要： A four-wheel steering system includes a front wheel turning mechanism which turns the front wheels in response to the turning of the steering wheel, a rear wheel turning mechanism which turns the rear wheels in response to the turning of the steering wheel, and a power steering mechanism. The rear wheel turning mechanism changes the rear wheel turning angle ratio, which is the ratio of the rear wheel turning angle to the front wheel turning angle on the basis of predetermined rear wheel turning angle ratio characteristic curve. A selecting switch selects one of a plurality of rear wheel turning angle ratio characteristic curves according to the running condition of the vehicle and causes the rear wheel turning mechanism to change the rear wheel turning angle ratio on the basis of the rear wheel turning angle ratio characteristic curve selected. The assisting force of the power steering mechanism is changed according to the rear wheel turning angle ratio characteristic curve selected by the selecting switch.
