摘要： A suspension control system is designed to adjust suspension characteristics between hard and soft for bounding and rebounding stroke independently of each other. The system has a sensor means for monitoring speed of a vehicular body as a sprung mass for producing a vehicle body speed indicative signal, which vehicle body speed indicative signal has a variable signal polarity depending upon the direction of vibration, and a sensor means for monitoring relative speed between the vehicular body and a vehicular wheel as an unsprung mass for producing a relative speed indicative signal which also has a variable signal polarity depending upon the direction of relative movement of the vehicular body and the vehicular wheel. A control unit detects a combination of signal polarities of the vehicle body speed indicative signal and the relative speed indicative signal for adjusting damping characteristics for bounding and rebounding vibration independently of each other and depending on the detected combination.

摘要： A suspension control system for an automotive vehicle is provided. This suspension control system comprises variable damping force shock absorbers and a control unit which controls the shock absorbers to assume damping force characteristics in a range between preselected higher and lower damping coefficients. The control unit is operable to provide a control parameter indicative of bouncing motion of a vehicle body based on sprung vertical speed to determine a damping coefficient against the bouncing motion. When the control parameter is greater than a threshold value, the damping coefficient is modified to a lower value, while when the control parameter is less than the threshold value, the damping coefficient is modified to a higher value. With this damping coefficient modification, the bouncing motion is suppressed effectively while assuring passenger comfort.

摘要： In order to enable a reduction in the weight of a bracket which forms part of a suspension strut, the bracket is press formed from sheet metal in a manner which forms first and second main sections, a bridge-like connecting section and a U-shaped connection flange which extends along all three of the just mentioned sections. The bracket components are configured so as to have two or more hem-cylindrical shaped reduced diameter portions which fit against the outer periphery of a strut tube and which have edges along which welds can be formed. Box-like projected sections defined in the two main sections between the hemi-cylindrical portions define spaces which have rectangular cross-sections about the periphery of the strut tube.

摘要： A rotary damper includes: a pressure generating mechanism portion A for relatively pivoting swingable vanes 4a and 4b with respect to stationary vanes 2a and 2b located on a casing 1 so as to vary reverse proportionally a pressure of a fluid filled within two pressure chambers 5a, 5b, 6a, and 6b; and a damping force generating mechanism portion B which limits a movement of the fluid based on a pressure variation generation at the pressure generating mechanism portion A to generate the damping force. A first transmission mechanism portion C and a second transmission mechanism portion D are interposed between both mechanism portions A and B, each of the first and second transmission mechanism portions C and D being capable of moving the fluid and transmitting the fluid pressure via movable first bellows 12 and second bellows 13. The fluid having a viscosity at least higher than the fluid filled in the flow passage located in the damping force generating mechanism portion B is used as the fluid filled in both of the pressure chambers 5a, 5b, 6a, and 6b in the pressure generating mechanism portion A.

摘要： A shock absorber has a cylinder tube coaxially arranged with a strut tube for defining therebetween an annular reservoir chamber and an upper reservoir chamber which is separated from the annular reservoir chamber. A first fluid path is defined for permitting fluid flow from a lower fluid chamber in the cylinder tube to an upper fluid chamber and the annular reservoir chamber in response to bounding stroke of vibration. A second fluid path is also defined for permitting fluid flow from the lower fluid chamber and the annular reservoir chamber to the upper fluid chamber and the upper reservoir chamber, in response to rebounding stroke of vibration. A first flow restriction means is disposed in the first path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics. A second flow restriction means is also disposed in the second path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics.
