Patent ES-8204958-A1 (ES)
Title: Steering gear for motor vehicles
IPC: B62D5/24
Filed: 1981-07-07
Abstract: A booster steering servomotor having a piston is pressurized and exhausted by a valve having a rotary valve plug within a valve sleeve and coacting flow control grooves wherein means for centering the rotary valve plug and steering mechanism of the vehicle wheels is effected by hydraulic power after a steering operation. Accordingly, little or no resort to axle geometry is required for such purpose thereby saving the energy normally utilized in the steering operation. Such energy expenditure has been necessary to put wheel restoring force in the axle geometry, e.g., due to inclination of king pins. In essence, the components effect rotation of the rotary valve plug during steering return in a direction to pressurize the servomotor pressure chamber which has been previously non-pressurized to bring the steering linkages back to straight ahead steering. The effect is achieved by increasing return bias energy stored in a fluid pressure chamber causing a return of the valve members, when steering force is released, beyond the neutral position for briefly reversely pressurizing the servomotor. The arrangement uses sleeve means having a cam action, which sleeve means are slotted for radial flexibility to take up play in the mechanism assembly.
