A stabilizer link includes a support bar, and ball joints. The ball joint includes a ball stud including a ball portion and a stud portion, and a housing that turnably supports the ball portion of the ball stud. The stabilizer is formed of a rod-shaped member made of metal. Mounting portions to which the stabilizer links are to be joined are respectively provided at both ends of the stabilizer. Through-holes through which the stud portions of the ball studs are to be inserted are respectively provided in the mounting portions. The stabilizer link is joined to the stabilizer by press-fitting the stud portion of the ball stud into the through-hole of the mounting portion.

An actuator device (1) for an adjustable roll stabilizer (2) of a motor vehicle, with a housing (4) that extends in the direction of a rotational axis (3) and an actuator (5) arranged in the housing. The actuator device (1) can be operated to twist two stabilizer sections (7a, 7b) relative to one another about the rotational axis (3) and the two stabilizer sections (7a, 7b) are attached to opposite ends (6a, 6b) of the actuator device (1). An engagement contour (8) is formed on the housing (4), which is suitable for immobilizing the housing during the application of torque (M1) to the housing (4) in a direction around the rotational axis (3).

An electromechanical roll stabilizer for a motor vehicle includes a housing, a rotor position sensor board, and an actuator torque sensor board. The housing has a motor unit that has a stator and a rotor integrated therein. The rotor position sensor board and the actuator torque sensor board are arranged between two stabilizer halves. The actuator torque sensor board has a digitization and transmission unit for digitizing the sensed torque and transmitting the digitized torque to a data forwarding module arranged on the rotor position sensor board. The rotor position sensor board has a rotor position detection unit for sensing and digitizing the rotor position and a data processing unit. The sensing of the rotor position can be triggered by at least one command signal of a controller to the rotor position detection unit. The data processing unit is provided to process the sensed measured values.

An electric resistance welded steel pipe for manufacturing a hollow stabilizer has a Rankford value in a pipe longitudinal direction of from 0.7 to less than 1.0. The electric resistance welded steel pipe is subjected to cold bending and then to a heat treatment including quenching and tempering to manufacture a stabilizer. The cold bending is cold rotary draw bending. When bent with a bend radius of from 1.0 times to 3.0 times an outer diameter of the pipe before cold bending, a flattening ratio is from 0% to 10%, a thickness reduction rate on a bending outside and a thickness increase rate on a bending inside are from 0% to 10%, and additionally, a circumferential length change of a bending center portion is from 0% to 10%. A Vickers hardness of the stabilizer after the heat treatment is adjusted to from 400 HV to less than 580 HV.

A stabilizer includes a stabilizer bar and a rubber bush. The stabilizer bar includes a bar body made of a steel and a coating film covering the bar body. The coating film is formed on the surface of the bar body by using a resin having a water contact angle of more than 65°. By performing surface treatment for reducing the contact angle of the coating film present on an attachment part, the contact angle of the attachment part is changed to 65° or less. A pre-cured liquid adhesive agent is applied to an inner surface (adhesion surface) of the rubber bush. After a region including the attachment part of the stabilizer bar is heated, the rubber bush is overlaid on the attachment part. The adhesive agent is cured in a state where the rubber bush is pressed.

An axial ball joint includes a ball stud including a stud portion and a ball portion; a metal housing configured to rotatably support the ball portion of the ball stud; a resin ball sheet provided in an interposed manner between the ball portion and the housing. The housing is formed in a bottomed cylindrical shape by press work. The housing has a bottom wall and a peripheral side wall which are set respectively to thicknesses substantially equal to each other. The bottom wall and the peripheral side wall of the housing have therebetween a boundary portion formed with multiple rib portions which project in a brace shape from outside to inside of the housing.

A torsion spring arrangement for a wheel suspension of a motor vehicle, including two torsion bars arranged coaxially one inside another and also a spring element, which is arranged axially-parallel to the two coaxial torsion bars and can be mounted on the motor vehicle body via a bearing position, wherein the radial outer hollow-cylindrical torsion bar can be mounted on the motor vehicle body side and is connected in a rotationally-fixed manner to an output lever fastenable on a wheel guiding element and the radial inner torsion bar is connected in a rotationally-fixed manner to the outer torsion bar and is connected in a rotationally-fixed manner via a coupling to the spring element.

Methods and systems are provided for controlling operation of a stabilizer bar of a vehicle. In one example, a stabilizer bar includes two shafts joined together by a gas-actuated decoupler. The decoupler may be actuated in order to enable each of the shafts to twist relative to each other.

A vehicle has left and right suspension arms operatively connecting left and right ground-engaging members to the vehicle's frame. An anti-roll bar assembly operatively connects the left and right suspension arms. The anti-roll bar assembly includes: an anti-roll bar having left and right end portions operatively connected to the left and right suspension arms, and at least one anti-roll bar connection assembly connecting a middle portion of the anti-roll bar to the frame. Each of the at least one anti-roll bar connection assembly includes: an elastomeric insert mounted to the anti-roll bar, the elastomeric insert engaging the anti-roll bar such that an inner surface of the elastomeric insert rotates together with the anti-roll bar; and a mounting bracket connected to the frame and at least partly enclosing the elastomeric insert, an outer surface of the elastomeric insert being rotatably fixed relative to the mounting bracket.

A torsion bar for a stabiliser of a motor vehicle, on the axial ends of which a respective stabiliser limb can be rotationally fixed. In the region of the axial ends thereof, the torsion bar is coated with an adhesive coating and a protective layer covering the adhesive coating, wherein the adhesive coating is designed as a solid adhesive coating that can be activated after at least partial removal of the protective layer.
