  • Patent number: 11427245
    Abstract: An actuator of a steering system having a housing (2), a spindle drive arranged in the housing (2) which includes an axially movable spindle (5) that engages with a spindle nut (6) mounted in a fixed position. The spindle has at least one fastening end (8, 9), and at least one bearing journal (10, 11) arranged and able to move in the housing (2). The journal is connected to the at least one fastening end (8, 9) of the spindle (5), with at least one joint connection component (3, 4) which is arranged outside the housing (2) and is connected to the at least one bearing journal (10, 11). The at least one bearing journal (10, 11, 110) has a constriction (10v, 11v) that forms a flexible zone (122).

  • Patent number: 11420492
    Abstract: 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).

  • Patent number: 10150342
    Abstract: A component connection for a wheel suspension of a motor vehicle, with a control arm having a mounting, in particular a rubber mounting, at least at one of its ends. An inner sleeve and a connection component, in particular a wheel carrier, are fixed to one another by a fixing element. The fixing element presses a first contact surface of the inner sleeve, in the axial direction, toward the connection component against an abutment surface of the connection component. The connection component has a supporting surface against which a second contact surface of the inner sleeve rests. Furthermore, the supporting surface is inclined relative to the abutment surface in such a manner that transverse forces occurring, in the radial direction in the area of the mounting, can be supported.
