  • Publication number: 20190250066
    Abstract: A monitoring method and monitoring apparatus for the remaining life of a bearing are provided. The monitoring method comprises: during the operation of a bearing, determining a position where a defect of the bearing is located, and determining a size of the defect (S10); according to the position where the defect is located and a set condition, determining a failure mode of the bearing as well as an expansion rate and a failure value of the defect in the failure mode (S20), the failure value being a maximum value that the defect can reach when the bearing fails; and based on the size, expansion rate and failure value of the defect, obtaining the remaining life of the bearing (S30). The monitoring method and monitoring apparatus determine the remaining service life of a bearing, so that maintenance personnel can arrange a maintenance plan and counter measures in advance.

  • Publication number: 20190248203
    Abstract: An electromechanical chassis actuator includes a single electric motor and two screw drives. The two screw drives use a common threaded spindle. A spindle nut of the first screw drive is rotationally fixed to the electric motor's rotor and engages the threaded spindle in a back-driveable manner. A spindle nut of the second screw drive is selectively coupled to the electric motor's rotor by a coupler and engages the threaded spindle in a self-locking (not back-driveable) manner. When the coupler is in an engaged position, the actuator operates in a level-adjustment mode. When the coupler is in a released position, the actuator operates in a damping mode.
