Abstract
An anti-roll system in a vehicle equipped with a power steering system for producing a steering reactive force modulatable by a speed at which the vehicle is running. The system introduces hydraulic pressure for the steering reactive force into suspension units on one side of the vehicle depending on steering directions, thereby preventing the roll of the vehicle body due to centrifugal forces exerted while the vehicle is being turned. An excessively inclined attitude of the vehicle during the turning thereof is thus corrected for an increased degree of maneuverability and safety of the vehicle.
Claims8
An anti-roll system for a vehicle equipped with a power steering system including a hydraulic pressure reaction chamber for producing a steering reactive force, and means for modulating said steering reactive force by the speed at which the vehicle is moving, said system comprising:
- damper means having at least a cylinder and a piston, said damper means being disposed between the vehicle body and each of the vehicle wheels;
- said damper means being in fluid communication with said hydraulic pressure reaction chamber in said power steering system;
- means for selectively connecting said hydraulic pressure reaction chamber with those of said damper means disposed on either side of said vehicle in response to rotation of a steering wheel of said vehicle in a selected steering direction, said means being connected between said hydraulic pressure reaction chamber and said damper means;
- and
- the hydraulic pressure in said reaction chamber being introduced, while said vehicle is being turned, into said damper means disposed on the radial outermost side of a circle along which said vehicle is being turned, depending on said selected steering direction, so as to control the roll of the vehicle body.
