  • Patent number: 10369859
    Abstract: In a motor vehicle chassis, at least one wheel suspension, which comprises a spring in the form of a coil spring, has associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the coil spring. The cylinder-piston arrangement can be supplied by a decentral hydraulic aggregate which is associated with the relevant wheel and comprises a storage container for hydraulic fluid and a hydraulic pump driven by an electric motor. At least the electric motor of the hydraulic aggregate is situated within the coil spring.

  • Patent number: 10350958
    Abstract: A hydraulic level-adjustment device has a reservoir, a reversible hydraulic unit with a hydraulic pump, and a single-acting hydraulic linear actuator. To lift a vehicle chassis, the working space of the linear actuator can be pressurized by the hydraulic pump operated in its first pumping direction via its first pump connection and a fill line with a fill-check valve arranged therein. To lower the chassis, via its second pump connection, the hydraulic pump, operated in the reverse pumping direction, pumps hydraulic fluid into the reservoir via an outflow line with a throttle unit arranged therein. The pressure present upstream of the throttle unit acts on the control connection of a lockable, drainage-check valve via a control line and opens same, so that, under the weight of the motor vehicle, hydraulic fluid is forced out of the working space of the hydraulic linear actuator into the reservoir via the drainage line.

  • Patent number: 10308090
    Abstract: In a motor vehicle chassis, all four wheel suspensions each have associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the relevant spring and is supplied by a decentral hydraulic aggregate. The hydraulic height adjustment devices each comprise a complex, integrated electrohydraulic adjustment assembly comprising the allocated hydraulic aggregate and the associated cylinder-piston arrangement and having a specific adapter into which the allocated cylinder-piston arrangement is integrated in such a way that there are no exposed hydraulic lines between the allocated hydraulic pump and the associated cylinder-piston arrangement. The front wheel height adjustment devices and the rear wheel height adjustment devices differ in terms of the adapter.

  • Publication number: 20030015889
    Abstract: A method and apparatus for the actuation of a convertible top system on vehicles whereby the convertible top may be received in its resting position in a compartment that is securable by a cover and whereby the convertible top may be unfolded and secured after opening of the cover, for which purpose there are controllable drive elements provided for the cover and the convertible top. The cover (1) and the convertible top (3) are essentially moved in a parallel manner under certain operational conditions to realize a loading-assistance function in a simple and functionally flexible manner, whereby the convertible top (3) remains in its resting, folded position. The control arrangement for the drive elements of the convertible top system is provided thereby with a switch position in which only one drive element (5) or a group of drive elements is triggered, which lifts the cover (3) from its resting position.

  • Patent number: 6267432
    Abstract: A hydraulic actuating system for movable parts, particularly for hinged covers on vehicles, includes at least one or more working cylinders with a piston equipped with sealing means pressing against the cylinder wall. A control unit is connected with one or all cylinders, and a pressure sensor connected to a control unit. Devices on the cylinder and piston are designed to cause pressure modulation in the cylinder and a common hydraulic circuit. The outgoing signals from the pressure sensor, are changed corresponding to the pressure modulations and are transmitted to the control unit to be used for position control and/or identification of one or all cylinders by the control unit.

  • Patent number: 6256987
    Abstract: A hydraulic operating apparatus, especially for a vehicle covering, includes a reversible pump (2) which, via hydraulic lines (3, 4), one of which is in all cases provided with an unblockable check valve (7), is connected with the working chambers of at least one double-acting piston-cylinder arrangement (1). In order to make possible a very flexible supply and control of mutually independently operated piston-cylinder arrangements with a minimum of constructive and control-technical effort, additional hydraulic lines (10, 11) branch off from both hydraulic lines (3, 4) of the reversible pump, into which the check valves are placed, which additional hydraulic lines lead into a common hydraulic line (12) to at least one additional piston cylinder arrangement (13, 14).
