摘要： PURPOSE:To make stable car height controlling come to fruition as a whole, by setting a pseudo-desired position according to a target difference between an actual position and a desired regulating position of each of plural car height control mechanisms and according to the position, making a control unit generate a control signal. CONSTITUTION:In case of a device which constitutes each of plural car height control mechanisms in a way of combining each of normally-closed type three- position solenoid valves 17 and 18 on shock absorbers 11 and 12 for front wheel use with a common, normally-closed three-position solenoid valve 19 on shock absorbers 13 and 14 for rear wheel use, each of car height control sensors 25- 28 generating an actual position signal after car height controlled is additionally installed in each of these shock absorbers 11-14. Each position signal is inputted into a control unit together with an output signal out of a setter (unillustrated herein) altering a desired regulated position. And, a pseudo-desired position commensurate to a target difference between an actual position and a desired position is set at every car height control mechanism, thereby making the control unit generate a control signal to each car height control mechanism according to the pseudo-desired position and the actual position.

摘要： PURPOSE:To improve the response in lane change mode etc. at high speed by feeding the fluid into one of hollow vessels and draining the other when both the vehicle speed and steering angle become larger than a predetermined value. CONSTITUTION:The vehicle speed and steering angle are inputted to a control circuit 16 respectively by sensors 17, 18, and when the vehicle speed 17 and steering angle 18 exceed the respective predetermined value, the control circuit 16 outputs an activating signal to solenoid valves 13A, 13B, 14A, 14B. The solenoid valves 13A, 13B, 14A, 14B are so activated that an inner hollow vessel 8A may be fed with the fluid and an outer hollow vessel 8B may be drained of the fluid. Because of this, the shock absorber joint is displaced outward of the vehicle relative to the upper support to cause a larger wheel camber angle. When decelerating, a reverse movement takes place, and the normal camber angle will result. In this manner, the handling at high speeds can be improved.

摘要： PURPOSE:To enhance the drive comfortability of a vehicle, by providing a suspension bushing which is disposed between the top end part of a shock-absorber and a coupling part on a vehicle body and which may be filled therein with pressure fluid, so that the spring constant of the suspension bushing is decreased in the case of that the vehicle runs with the driver alone. CONSTITUTION:A resilient member 23 incorporated therein with a plurality of hollow bags 36 which are connected with a pressure fluid source through a hose 26 and a pressure control valve A, is disposed in a suspension bushing between outer and inner support members 14, 22. The pressure control valve A comprises a first solenoid valve 53 which communicates a pump 51 with an outlet upon energization but a reservoir 52 with the outlet upon denergization, and a second solenoid valve 54 which is opened upon energization but is closed upon deenergization. When a control circuit B judges that the driver alone climbs the vehicle upon stopping of the vehicle, both solenoid valves 53, 54 are energized to raise the vehicle height, and thereafter, upon starting the second solenoid valve 54 is alone energized for a predetermined time period to decrease the internal pressure so that the spring constant is decreased.

摘要： PURPOSE:To make drive comfortableness and controllability satisfactory, by increasing the damping force of a shock-absorber device when the operational period of an antiskid mechanism exceeds a predetermined value, so that the self- exciting vibration of a vehicle upon anti-skid operation is prevented. CONSTITUTION:A plug 38 is air-tightly fitted into an open cylinder 14a which is formed in the lateral surface of the outer cylinder 14 of a cylinder assembly 10 in a hydraulic shock absorber mechanism. The plug 38 is formed with a variable orifice 40 having one end communicated with a first hydraulic chamber 202 through a conduit 42 and a communication passage 22a in a top holder 22 and the other end communicated with a second hydraulic chamber 204 through a hydraulic reservoir 200. Further, a grooved hole 38 orthogonal to the varaible orifice 40 is formed, and a valve part 52a of a plunger 52 which is actuated by a solenoid 44 is inserted in the grooved hole 38a. The solenoid 44 is energized when the self-exciting vibration upon anti-skid operation is required to be prevented, for blocking the variable orifice 40 with the valve part 52a.

摘要： PURPOSE:To improve feeling upon riding on a vehicle or the steering stability of the vehicle by a method wherein a running condition such as the sudden starting or the high-speed running of the vehicle is detected from the opening degree signal of a throttle and a shift position signal to increase the damping force of a shock absorber temporarily. CONSTITUTION:When an exciting current is supplied to solenoid coil 50 and a plunger 52 is attracted and moved to the left against a spring 54, a variable orifice 40 is closed by a valve 52a and, under this condition, the communicating sectional area of a shock absorber becomes a small area determined by orifices 30, 32, or the same 33, 34, thereby enabling to vary and adjust the damping force temporarily. Accordingly, the comforatable feeling upon riding on a vehicle and the good steering stability of the vehicle may be obtained by a method wherein the running condition of the vehicle such as the sudden starting or the high-speed running, for example, is detected by the opening degree signal of the throttle for an engine and the shift position signal of a speed change mechanism by exciting the solneoid coil 50.
