摘要： A suspension device for automobile performs changing-over of the damping force of a shock absorber and the spring constant of a suspension spring by an output from an acceleration sensor or an output from a road clearance sensor mounted on the vehicle body. The changing operation is not performed by magnitude of an output but is performed only when an output greater that a predetermined level continues for a predetermined time period to avoid unnecessary change-over operations of the suspension characteristic during cruising a rough road.

摘要： When an automobile or other vehicle travels over a bump with a suspension in its switchable suspension system kept in a "soft" state, the car body pitches violently. This pitching is reduced by turning the suspension into a "hard" state by increasing the damping capacity of its shock absorber and the spring constant of its air-spring chambers in accordance with a signal supplied from a car-height sensor detecting the compressed or stretched condition of the suspension. The change of the spring constant is executed with the following construction: an auxiliary air-spring chamber resting above a main air-spring chamber surrounding a piston rod, and an air passage within the piston rod for intercommunicating the main and auxiliary air-spring chambers are provided in the system, and the connection and disconnection between the two chambers through the air passage are controlled by the piston rod and a control rod extending in the piston rod.

摘要： The characteristic of the suspension is held to be a soft one when the vehicle is running along a flat surface, while it is automatically switched by the switch unit to a hard one when the cycle period T of vertical vibration of the vehicle height becomes near the cycle of the natural vibration of sprung mass of the suspension at the time of running along a road having an irregular surface or jumping a projection, thereby suppressing the resonance of the vehicle body due to external force applied from the road to improve the comfortability.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed. When steering wheel is quickly returned toward the center position at the time of a slalom running, it is detected from the steering angular velocity and vehicle velocity that the vehicle body has begun to be returned to a neutral state, and communication control valves are opened before the reaching of the center position, i.e., before the steering angle reaches an insensitive range. Rolling control thus can be improved without delay in the restoration of the position of the vehicle body even at the time of a high speed slalom running, at which time the steering wheel is repeatedly operated quickly.

摘要： In a vehicle suspension apparatus having air spring chambers between the vehicle body and the respective wheels to perform height and position control modes by controlling supply control valve means for supplying air to the air spring chambers and exhaust control valve means for exhausting air from the air spring chambers, the vehicle suspension apparatus has a high-pressure reserve tank connected to the respective chambers through the supply control valves, a first compressor for supplying compressed air to the high-pressure reserve tank, a low-pressure reserve tank connected to the respective chambers through the corresponding exhaust control valves and the suction port of the first compressor, and a second compressor for supplying atmospheric air to the high-pressure reserve tank through a check valve and a drier arranged between the check valve and the second compressor. In the position control mode, the compressed air is exhausted from the chambers to the low-pressure reserve tank through the exhaust control valves. In the height control mode, the compressed air is slowly exhausted from the corresponding chambers through the exhaust control valve means via the drier, thereby regenerating the drier during height down control.

摘要： In a vehicle suspension apparatus, front and rear wheel suspension units respectively have air spring chambers. Air is supplied to predetermined air spring chambers from an air source through a supply control valve, and at the same time air is exhausted from remaining air spring chambers through an exhaust control valve. Three-directional valves are inserted between the respective air spring chambers and the exhaust control valve. One end of a front wheel communication path is connected to the front left wheel three-directional valve and the other end of the path is connected to the front right wheel three-directional valve. Similarly, one end of a rear wheel communication path is connected to the rear left wheel three-directional valve and the other end of the path is connected to the rear right wheel three-directional valve. The air passing through the supply control valve is supplied to the front wheel air spring chambers through the front wheel communication path or to the rear wheel air spring chambers through the rear wheel communication path. Each of the three-directional valves can take the first position where the air spring chambers communicate with the supply control valve or the second position where the air spring chambers communicate with the exhaust control valve, thereby decreasing the numbers of valves and paths so as to perform position control.

摘要： A vehicle suspension apparatus has air spring chamber provided at a suspension unit for supporting a rear wheel, air supply means for supplying air to the air spring chamber of the suspension unit for supporting the rear wheel through supply opening and closing valve, air exhaust means for exhausting air from the air spring means of the suspension unit for supporting the rear wheel, a parking brake sensor for detecting the operated state of a parking brake, and a shift position detecting sensor for detecting the shift position of an automatic transmission having a fluid drive unit for transmitting drive power to wheels. The parking brake sensor detects whether or not the parking brake is engaged. The shift position detecting sensor detects whether or not the shift position of the automatic transmission is operated from any of parking position (P) and neutral position (N) to running position (D, L, 2) to raise the vehicle height of the rear wheel side to supply air to the air spring chamber of the rear wheel side. The fact that the shifting position of the automatic transmission is operated from either the parking position (P) or the neutral position (N) to the running position (R) is detected to exhaust air from the air spring chamber of the rear wheel side to lower the vehicle height of the rear wheel.

摘要： If a deceleration exeeds first set value G1 within set time T1 after the brake is depressed, a set amount of fluid is supplied to the fluid spring chamber of each front-wheel suspension unit. If a deceleration exceeds the second set value G2 when set time T1 or more has elapsed upon this operation, a set amount of fluid is exhausted from the fluid spring chamber of each rearwheel suspension unit. With this operation, since braking action for gradually increasing a deceleration is controlled by two stages, uncomfortableness which passangers feel in anti-nose-dive control can be greatly reduced. In addition, control is not performed only by depressing the brake pedal if an acutal deceleration is smaller than first set value G1. Even when a deceleration exceeds first set value G1 upon depression of the brake pedal, if the time when the deceleration exceeds first set value G1 exceeds set time T1, it is determined that a gradual braking operation is performed, so that only control for increasing a damping force is performed.

摘要： When vibrations having a period at which pitching tends to occur in a vehicle body is detected, if its amplitude falls out of the range between "H" and "L", a control unit increases the damping force of each suspension unit by using an actuator. In addition, if the amplitude falls out of the range between "HH" and "LL", the control unit supplies a predetermined amount of air to each air spring chamber in response to an upward displacement of vehicle height, and exhausts a predetermined amount of air from each air spring chamber in response to a downward displacement of vehicle height.
