Abstract: A trailing arm suspension includes a holder pivotally supported on a vehicle body by a first pivot shaft extending substantially longitudinally of the vehicle body and supporting a second pivot shaft extending substantially transversely of the vehicle body, a trailing arm pivotally supported by the second pivot shaft on the holder and having a spindle mounted on a rear portion thereof for rotatably supporting a wheel, and a plurality of links have first ends thereof coupled to the trailing arm and extending substantially transversely of the vehicle body. The point at which the trailing arm is pivotally supported by the second pivot shaft can easily be displaced transversely through swinging movement of the holder about the axis of the first pivot shaft. A rubber bushing interposed between the trailing arm and the second pivot shaft can be harder or higher in rubber rigidity in the longitudinal and vertical directions of the vehicle body for limiting changes in wheel alignment when wheels are driven or braked.

Abstract: A steering system for a vehicle having a steering wheel and front and rear wheels, including a front steering sub-system for steering the front wheels in accordance with the steering angle of the steering wheel and a rear steering sub-system for steering the rear wheels in the same and opposite directions with respect to the front wheels in accordance with the steering angle of the steering wheel. The steering system is provided with a rack and pinion type variable-ratio mechanism for varying the ratio of the steered angle of at least either of the front or rear wheels to the steering angle of the steering wheel in accordance with the magnitude of the steering angle of the steering wheel. The design freedom in setting a functional relation between the steering angle of the steering wheel and the turning curvature of the vehicle is thus maximized. Moreover, selective setting is permitted for change of ratio of the steered angle of the rear wheels to the steering angle in the vicinity of the initial position of the steering wheel. Further, there is permitted a favorable use of available vehicle dimensions to achieve an optimum feeling characteristic of steering operation.

Abstract: A steering system for a motor vehicle having power steering means including an actuator for turning steerable road wheels of the motor vehicle includes a control mechanism for eliminating a deviation between a desired direction of travel of the motor vehicle and an actual direction of travel of the motor vehicle, based on an output signal from a direction indicating mechanism which indicates the desired direction and an output signal from a direction detecting mechanism which detects the actual direction. The control mechanism determines a target turning angle for the steerable road wheels dependent on the deviation between the desired direction and the actual direction, and controls the power steering mechanism to turn the steerable road wheels up to the target turning angle.
