A system and method for operating a motor vehicle having an active roll control system and an air suspension system including operating the air suspension system in a normal mode, according to a normal air spring setting. Upon determining a fault or malfunction of the active roll control system operating the air suspension in a fallback mode, according to a fallback air spring setting, wherein the fallback mode is different from the normal mode.

A motor vehicle series includes two different motor vehicle variants. The two motor vehicle variants include an identically designed chassis component fastening device, to which a stabilizer is fastened in the first motor vehicle variant and a motor-pump unit assembly with a motor-pump unit of a hydraulic damping system is fastened in the second motor vehicle variant. The motor-pump unit assembly includes a motor-pump unit for a hydraulic damping system. A holding tube is fastened to the motor-pump unit. A holding element, which is configured to be mounted on a chassis component fastening device of a motor vehicle, is fastened to the end of the holding tube facing away from the motor-pump unit.

An active suspension system comprises at least one biasing device configured to support a body from a structure, and at least one motor. A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.

A passenger vehicle provided with a steering handle (15) and configured such that an attitude angle of the driver seat surface (14a) relative to a horizontal reference plane is changeable, so that a first attitude changing operation switch (25) and a second attitude changing operation switch (26) for changing the attitude angle are disposed in such positions as to be operable with a thumb of the driver of the vehicle from a steering handle grip (18) of the steering handle (15).

Left and right stabilizer bars are provided between left and right wheels of a vehicle. A control unit controls an actuator to control a rotation angle of the right stabilizer bar with respect to the left stabilizer bar. The control unit determines whether the vehicle is moving, whether a vehicle speed is less than a first threshold value, and whether a vehicle state is in transition from a moving state to a stopped state. A detection unit detects a control amount of the actuator. When the vehicle is moving, the vehicle speed is less than the first threshold value, the vehicle state is in transition from the moving state to the stopped state, and the control amount of the actuator is greater than zero, the control unit decreases the control amount of the actuator such that the control amount of the actuator becomes zero before the vehicle speed becomes zero.

Disclosed herein is an active roll stabilizer. The active roll stabilizer includes a pair of stabilizer bars installed between left and right wheels of a vehicle and an actuator which connects the pair of stabilizer bars and transmits a rotational force to the pair of stabilizer bars, wherein the actuator includes a motor configured to generate the rotational force, a housing coupled to a portion between the pair of stabilizer bars and having the motor disposed inside the housing, a damping part disposed on an extension line of a rotational shaft of the motor inside the housing and configured to absorb vibrations generated at the motor and the pair of stabilizer bars, and a torque measurement sensing part configured to measure a torque transmitted by the rotational force inside the damping part.

An elastomer coupling for an electromechanical actuator, having a drive part and a driven part, wherein either the drive part or the driven part has multiple radially outwardly extending webs arranged so as to be distributed about an axis of rotation, and the respective other part has radially inwardly extending webs arranged on the inner side of a tubular body, wherein a radially inwardly and a radially outwardly extending web engage into one another and form a pocket in which there is received an elastic molded body produced from an elastomer, wherein, in at least one pocket, there is received a spring element which generates a pretensioning force, which spring element is attached either to an inwardly extending or to an outwardly extending web and is spring-loaded against an adjacent web.

A vehicle lower section structure includes: a suspension member including a side rail extending in a vehicle front-rear direction, the side rail including a front joint portion and a rear joint portion, the front joint portion being disposed on a front side of the rear joint portion in the vehicle front-rear direction; a securing member joined to the side rail at the front joint portion and the rear joint portion; and a stabilizer secured to the side rail by the securing member. The side rail includes a low-strength portion provided between the front joint portion and the rear joint portion and the low-strength portion has a strength lower than a strength of the front joint portion and the rear joint portion.

A traveling vehicle includes: a vehicle body frame, a pair of right and left front crawler traveling devices, a pair of right and left rear crawler traveling devices, a front suspension device that suspends the pair of right and left front crawler traveling devices on the vehicle body frame, and a rear suspension device that suspends the pair of right and left rear crawler traveling devices on the vehicle body frame. The front suspension device integrally suspends the pair of right and left front crawler traveling devices on the vehicle body frame and allows the pair of right and left front crawler traveling devices to be swingable in the vertical direction with respect to the vehicle body frame.

The present invention relates to a stabilizer for a vehicle which is installed between a pair of wheels of the vehicle and includes a first bar disposed to extend in a width direction of the vehicle; an actuator supported by a vehicle body of the vehicle and coupled to the first bar and a first connecting member to move the first bar in the width direction of the vehicle; and a second bar having one side connected to the first bar and the other side connected to one side of a wheel supporter which supports one wheel of the pair of wheels of the vehicle, wherein, when the first bar is moved in the width direction of the vehicle, the other side of the second bar is moved so that the one side of the wheel supporter is moved in an upper direction or a lower direction of the vehicle.
