Disclosed is a vehicle strut insulator that includes first and second bushes (100 and 200) having different hardness characteristics. The first bush (100) having a relatively high hardness is disposed in a left-right direction of a vehicle that affects the handling performance, and the second bush (200) having a relatively low hardness is disposed in a forward-backward direction of the vehicle that affects the ride comfort. Accordingly, the vehicle strut insulator can satisfy both requirements for handling performance, ride comfort and road noise performance.

An apparatus for controlling a stabilizer bar including: a steering angular velocity detection unit configured to detect a steering angular velocity of a vehicle in operation; a steering angle detection unit configured to detect a steering angle of the vehicle; and a control unit configured to determine whether the vehicle is turning, based on the steering angular velocity information and the steering angle information of the vehicle, and perform clutch coupling by driving a clutch of a stabilizer bar having the clutch applied thereto, when it is determined that the vehicle is turning. The control unit decides a clutch coupling time period in response to an instantaneous turning velocity of the vehicle, and performs the clutch coupling in response to the decided clutch coupling time period.

A shock absorber includes a suction passage permitting flow only from a reservoir toward a compression-side chamber, a rectification passage permitting flow only from the compression-side chamber toward an extension-side chamber, and a variable valve permitting flow only from the extension-side chamber toward the reservoir. A large chamber as a compression-side pressure chamber communicating with the compression-side chamber and an outer periphery chamber as an extension-side pressure chamber communicating with the extension-side chamber are partitioned in the shock absorber by a free piston that moves slidably within a bottom member serving as a housing. A compression-side pressure-receiving area of the free piston is larger than an extension-side pressure-receiving area. Therefore, even in the uniflow shock absorber with the extension-side chamber and the compression-side chamber at equal pressures during the contraction operation, the damping force is reduced under conditions in which high frequency is input since the free piston moves downward.

A vehicle strut assembly includes at least a strut member, a bearing assembly, a mounting bracket and a noise isolating member. The bearing assembly encircles an upper end portion of the strut member. The mounting bracket is configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle. The noise isolating member is installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly.

The anti-noise element (EAR) is applied to separate the end portions of each two spring blades (LM), superimposed and adjacent, of a spring bundle (FM) and comprises a metal plate (10) covered by a coating (20) in polyamide-11 thermoplastic resin and incorporating a median protrusion (12) to be fitted and retained into a corresponding hole (F) provided at the end portion of the spring blade (LM) against which the anti-noise element (EAR) is seated and retained.

A vibration damper comprising a working cylinder, which is subdivided by an axially movable piston on a piston rod into a first and a second working chamber filled with a damping medium is disclosed. The vibration damper has at least one compensating reservoir for receiving the damping medium displaced by the piston rod. There is a flow connection between the two working chambers, in which connection there is incorporated a pump assembly. The pump assembly has a fluctuation in the delivery volume with a constant power supply. At least one pulsation accumulator is arranged within the flow connection, wherein the volume and spring rate of the pulsation accumulator are matched to a frequency of a fluctuation of the delivery volume of the pump assembly.

An inertial regulation active suspension system based on posture deviation of a vehicle and a control method thereof are provided. The system comprises a vehicle body, an inertial measurement unit, an electronic control unit, a servo controller group, a plurality of wheels, suspension servo actuating cylinders respectively corresponding to the wheels, and displacement sensors for measuring a stroke of the suspension servo actuating cylinders. The electronic control unit reads posture parameters of the vehicle body measured by the inertial measurement unit, and calculates a deviation between the postures of the vehicle body at a current moment and at a previous moment, and then outputs posture control parameters to the servo controller group. The servo controller group controls extension and retraction of each of the suspension servo actuating cylinders according to the posture control parameters and displacement feedback values of the displacement sensors.

A method for reshaping an electric drive signal of a real-time damper in a sprung mass system includes detecting a periodic frequency and magnitude of a target periodic vibration of a sprung mass. The periodic vibration has velocity and elasticity components that are 90 degrees out-of-phase. An electric drive signal to the real-time damper is reshaped by a controller depending on polarity of the velocity component to thereby generate a composite drive signal. The damper is energized using the composite drive signal to modify a damper force. Reshaping the electric drive signal includes injecting a force and/or an intermittent drive suppression component onto the electric drive signal based on the frequency and magnitude. The sprung mass system may have a frame and body, motion and wheel speed sensors, the real-time dampers, road wheels, and a controller programmed to perform the method.

A device for fastening an air spring to a body portion of a motor vehicle, at least comprising an air spring cover, wherein the air spring cover comprises at least one fastening means, by means of which the air spring can be connected to the body portion of the motor vehicle, wherein, for attachment of the air spring, the fastening means is plugged through an opening of the body portion and is fixed to said body portion in a force-fitting manner by a securing element, wherein a first and a second plastics part are provided for acoustic decoupling of the air spring, wherein the first plastics part, is clamped between the body portion and the securing element, and the second plastics part is provided so as to be positioned below the body portion.

A coil spring includes a wire rod and an elastic coat provided on the wire rod. The coil spring includes a coil section including a plurality of coil portions. The wire rod includes a round cross-sectional portion, a cross-section varying portion, and a rectangular cross-sectional portion along the longitudinal direction of the wire rod. The cross section of the rectangular cross-sectional portion is substantially square and has a first plane and a second plane. The first plane and the second plane oppose each other in the coil section. The elastic coat is provided on at least one of the first plane and the second plane. The elastic coat is continuous from the round cross-sectional portion to the cross-sectional variation portion and the rectangular cross-sectional portion.
