  • Patent number: 10532625
    Abstract: Adjustable spring support includes a first spring plate and a second spring plate, wherein at least one of the spring plates is axially adjustable relative to the other spring plate by an actuator, wherein the actuator is supplied with pressure medium via a pump which is driven by a motor and which is connected to a supply receptacle, wherein the motor, the pump and the supply receptacle form a constructional unit, and the constructional unit provides a cylindrical surface of the actuator.

  • Patent number: 10434834
    Abstract: A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.

  • Patent number: 10427485
    Abstract: A method of operating a motor vehicle with a chassis system comprising at least two, preferably four vibration damper includes carrying out a body control and a wheel control with the chassis system, and controlling the energy supply for the chassis system via an energy control arrangement. A motor vehicle performing the method is also disclosed.

  • Publication number: 20170008558
    Abstract: An arrangement for connecting chassis parts, in particular a screw connection, between a structure made of a fiber-plastic composite and a metallic load-introducing element, designed as a traction member. The structure is double-walled having a first wall and at least a second wall spaced from the first wall. The first and second walls have each coaxially positioned recesses and a spacer, having a through hole, is positioned between the first and second walls. The load-introducing element extends through at least one recess and the hole of the spacer. The load-introducing element has a holding part assigned to it, and the load-introducing element and the holding part are connected to one another by a connecting segment. The connecting segment and/or the holding part essentially pass through the first and/or the second wall.

  • Patent number: 8910759
    Abstract: A vibration damper including a cylinder with a cylinder-side connection member. The at least one mounted component is fastened to the cylinder by a material bond. The cylinder and the mounted component are made of plastic. The mounted component and/or the cylinder are based on at least one ready-prepared semi-finished product that forms the surface of the vibration damper on at least one body side in the final state. Plastic supplemental volume fractions determine the finished body contour.

  • Patent number: 8297600
    Abstract: A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.

  • Publication number: 20110215209
    Abstract: A supporting tube for a vibration damper including an axial supporting surface on which rests an outer cylinder of the vibration damper. A fixing cap which holds a second axial supporting surface for securing the cylinder against loading in the opposing direction. The fixing cap is connected to the supporting tube by positive engagement, and separate locking elements for both parts are arranged between the fixing cap and the supporting tube, which locking elements position the outer cylinder relative to the supporting tube.
