A connecting structure which reduces a vibration effect of a power system on a vehicle body comprises a power system bracket, one end of the power system bracket being connected to a power system, another end being connected to a suspension, one end of the suspension being connected to a frame or a load-bearing vehicle body, another end being connected to an axle or wheels, the suspension being capable of attenuating and isolating high frequency vibrations produced by the power system. The power system is not directly connected to the vehicle body which is above shock absorbers, but rather connected to a suspension frame which is below the shock absorbers, extending the path whereby power system high frequency vibration energy is transferred to the vehicle body, so that the high frequency vibrations of the power system are effectively attenuated and isolated, and the vibrations of the vehicle body are reduced.

A linear actuator includes: a pinion shaft coaxially coupled to a motor shaft; a driven gear that is engaged with a pinion gear on the pinion shaft; a nut that rotates with the driven gear; a feed screw mechanism that converts rotation movement of the nut into linear movement of a rod; a coupling part allowing an outer peripheral surface of the motor shaft to be serration coupled to an inner peripheral surface of a vertical hole in the pinion shaft; and a pressurizing unit that generates a pressure that axially acts between e motor shaft and the pinion shaft in the coupling part.

A roll stabilizer, e.g., for a multitrack motor vehicle, with a divided torsion bar, between the mutually facing ends of which an actuator is arranged for transmission of a torsion moment. The actuator may have a housing which is connected to the one torsion bar part and houses a motor and a planetary gear mechanism connected to the motor, the gear output of which is connected to the other torsion bar part. and the planet wheels of which intermesh with a mating gear. A multistage planetary gear mechanism is provided, whose final planetary gear stage on the gear output side is equipped with planet wheels, wherein at least one of said planet wheels is divided into two axially adjacent spur gears which are rotatable relative to each other and between which a torsion spring is actively arranged. The divided planet wheel may be in play-free engagement with the mating gear.

A vehicle includes a suspension system, a sensor for measuring a vibration signal produced from the suspension system, and a microphone for measuring a noise signal in an interior of the vehicle caused by the vibration signal, wherein the sensor is installed at an interior sensor position determined based on an analysis of a level of contribution of the vibration signal to the noise signal, from among candidate sensor positions in the interior of the vehicle.

An acoustical absorber, which may take the form of a shock tower insulator, includes a body made from a sound insulating material and one or more serrated washers fixed to the body. The washers function to retain the body to mounting studs without the need for using a separate fastener.

Aspects of the present invention relate to a active roll bar damper assembly (1) suitable for an active roll bar (5). The active roll bar damper assembly (1) includes a first subassembly (15-1) and a second subassembly (15-2) for mounting to the active roll bar (5). The first subassembly (15-1) includes a rigid first mass (17) having a first aperture (27). At least one first spring (21-n) is disposed in the first aperture (27) for positioning between the active roll bar (5) and the first mass (17). The second subassembly (15-2) includes a rigid second mass (37) having a second aperture (47). At least one second spring (41-n) is disposed in the second aperture (47) for positioning between the active roll bar (5) and the first mass (17). The first and second masses (17, 37) are configured to engage each other to limit compression of the first and second springs (21-n, 41-n). Aspects of the present invention also relate to an active roll control system (3) including an active roll bar damper assembly (1); and a vehicle (V).

A method for operating an actuator of a torsion bar system of a wheel suspension of a motor vehicle is disclosed. The actuator is mounted on a carrier structure of the vehicle and actuation of the actuator changes a pre-tension acting on a wheel guide element of the wheel suspension. The method includes controlling an active aggregate support so as to reduce a vibration of a drive aggregate supported on the carrier structure via the active aggregate support adjacent to the actuator; and controlling the active aggregate support for reducing an operational vibration of the actuator.

A damping member (100) for a pneumatic valve (205) of a pneumatic system (201) of a vehicle (200a), in particular a utility vehicle (200b), is adapted to be mounted to an air outlet section (210) of the valve (205) which is used for exhausting pressurized air (220). The damping member (100) is adapted for damping sound emission of the pressurized air (220) and includes a scaffold structure (105). The scaffold structure (105) is adapted to damp the sound emission of the pressurized air (220) by conducting the air (220) through the scaffold structure (105).

The present disclosure relates to a noise reduction system for an automobile suspension for reducing structurally transmitted noise caused by vibrations generated when a damper of the suspension operates and entering the interior of the automobile. The noise reduction system comprises: a vibration detection unit that is mounted on the suspension damper; an anti-phase vibration generator that is mounted on a top mount portion of a vehicle body on which the suspension damper is mounted and generates vibration in an opposite phase to vibration generated when the damper operates to be applied to the top mount portion; and a control unit that receives a measurement value detected by the vibration detection unit, calculates a target anti-phase vibration, and controls the anti-phase vibration generator.
