  • Patent number: 8862344
    Abstract: A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.

  • Publication number: 20140105768
    Abstract: A hydrostatic actuator and an arrangement for attaching it to a receiving component are provided. The hydrostatic actuator has a master cylinder containing a housing and a piston movable axially within the housing which acts on a pressure chamber filled with a pressurizing agent. The piston is driven by a rotary-driven electric motor having a stator and a rotor, by a rolling planetary transmission that converts the rotary drive to an axial motion. In order to be able to produce such a hydrostatic actuator with little need for construction space, cost-effectively and with better quality, a supporting of the rolling planetary transmission is simplified, and the cooling and shielding of an electronic controller and the pressure behavior of the hydrostatic actuator is improved.

  • Publication number: 20130328420
    Abstract: A reluctance motor having a rotor and a stator that has a wound core, around which a stator coil is wound and which is open on one side and has legs, said legs being arranged around the periphery and forming spaced-apart pairs of legs. Multiple rotor teeth which are distributed around the periphery and periodically establish a magnetic flux between the legs radially engage between the legs. In order to positively change the characteristic curve of the magnetic flux of the legs and teeth, the teeth continuously form an area overlap with the legs in the direction of rotation of the rotor in accordance with the angle of rotation.

  • Patent number: 8396631
    Abstract: A controller for a motor vehicle with a carrier plate for receiving a component carrier with a component carrier foot. The carrier plate has a recess through which the component carrier can be passed and which is suitable for receiving the foot, wherein the dimensions of the recess in the region of the component carrier and in the region of the foot in the X/Y-direction correspond to maximum admissible dimensions of the component carrier and of the foot (5) in the X/Y-direction. In the Z-direction, a pressing geometry is arranged on the recess or on the foot such that after establishing a positive-fit or non-positive connection between the carrier plate and a system interface, the pressing geometry or a part that is arranged opposite the pressing geometry is in such a deformed state that the foot is in the recess in a fixed state and without play.

  • Patent number: 8173912
    Abstract: A housing for retaining an electronic component, including a lid and a lower part made of synthetic material, wherein the lid is joined in a force-fit manner to the lower part by clamping geometry, and in order to affix the electronic component in position, the lid applies a specified force (F) to the electronic component after being joined to the lower part due to its design. Here, the lid is designed in such a manner that the force (F) applied lies within a specified force range (B), and that the clamping geometry comprises a groove on the lower part and a ridge on the lid which grips into the groove, wherein a clamp web on the lower part or on the lid is arranged in such a manner that the lid is removably clamped to the lower part after being joined to the lower part with a force (F) which acts parallel to the clamping force (KF).

  • Patent number: 8059407
    Abstract: For a motor vehicle control device, a housing lid and a base plate form a hollow area that contains an interconnect device arranged on the inner side of the housing lid. The housing lid has at least one opening surrounding the interconnect device, adjacent to an electronic component and/or an electrical contact area on the interconnect device. On or in the opening, a flexible foil conductor strip is arranged with an end section thereof covering the opening. A lid plate covers the opening completely, and the interposed foil conductor strip is thus connected in an oil-tight manner with the housing lid. Electrical connection lines between the components and/or the contact areas on the interconnect device and an electrical contact area on the end section of the foil conductor strip create the electrical connection between the control electronics on the interconnect device and the surrounding area outside of the control device.
