  • Patent number: 6905004
    Abstract: An engagement wheel is mounted so that it can rotate relative to the drive shaft of a drive train in a motor vehicle. To allow rotational driving, the engagement wheel is operatively connected with an element that cannot be rotated relative to the drive shaft by at least one elastically deformable element mounted in the torque path between the engagement wheel and the rotationally fixed element. The elastically deformable element can absorb residual rotational energy of the drive train, when the engagement wheel is locked by a locking element, which may be in the form of a pawl.

  • Patent number: 6707186
    Abstract: A plurality of stator coils having coil ends are arranged on an annular stator yoke. Concentrically arranged connection conductors which are electrically insulated relative to one another have laterally projecting terminals for connecting to the ends of the stator coils. Receiving chambers arranged about the front side of the stator yoke receive the terminals of the connection conductors and fix the connection conductors in position. The receiving chambers are allocated to the coil ends which form an electric clamping connection by pairs with the terminals of the connection conductors at the receiving chambers.

  • Patent number: 6369473
    Abstract: A stator for an electrical machine includes a stator yoke and a plurality of stator coils arranged on the stator yoke. An interconnection arrangement is arranged on one end face of the stator yoke. The interconnection arrangement has connecting conductors which are electrically insulated from one another. The connecting conductors are arranged concentrically with respect to one another and each have a different diameter. The connecting conductors have connections for the ends of the stator coils and for connection to the electrical machine. To minimize the space requirement of the stator and simultaneously allow the stator coils to be automatically interconnected in an automated manner, the interconnection arrangement is arranged inside an area bounded by the stator coils. Furthermore, the connections for the ends of the stator coils include connection projections designed such that they project outward at an angle to the respective connecting conductor to attach the stator coil ends.

  • Patent number: 6361469
    Abstract: A parking lock for a vehicle having an electrical drive train including an electric machine with a rotor, a stator having a plurality of stator windings, and power electronics for controlling the electric machine, and a transmission prevents the vehicle from rolling away inadvertently. The parking lock has a mechanical component which is mechanically operatively connected to the rotor when the parking lock is operated to stop rotation of this rotor. The mechanical component has a ratchet wheel and a toothed catch. Furthermore, the parking lock has an electrical component designed such that it produces a short-circuit in the stator windings, at least temporarily, when it is intended to operate the parking lock. When the parking lock is operated, the electrical component is thus activated in a specific time interval before operation of the mechanical component. The short-circuit in the stator windings produces a severe braking torque, which brakes the rotor.

  • Patent number: 5826687
    Abstract: System for the control of the roll of a motor vehicle, the system including a number of valves and lines for the feed and control of an actuator. The actuator is coupled to a stabilizer by means of connections, whereby the lines and connections have a one-to-one correspondence, in that the coupling points which are relevant for operation are all realized so that they can only be connected in the correct pairings.

  • Patent number: 5632502
    Abstract: A rotary actuator having a cylinder and a motor shaft as well as end caps which define a working area, a number of ribs on the inside surface of the cylinder and an equal number of vanes on the motor shaft which divide the working area into work chambers, and seals inside grooves in the ribs and the vanes. The work chambers are alternately supplied with hydraulic medium, and the seals hydraulically separate the working chambers from one another. The seals are in the form of one-piece gasket members and there is a space between the seals and the side walls of the groove in the static rest position. The gasket member, via its end surfaces, its surfaces which define the height of the gasket member, and one side wall, perform a sealing function during operation of the rotary actuator.

  • Patent number: 5601165
    Abstract: A rotary actuator has a cylinder and a motor shaft as well as end caps which define a working area. A number of ribs extend from the inside wall surface of the cylinder and an equal number of vanes extend from the outside shell surface of the motor shaft. The ribs and vanes divide the working area into working chambers which are alternately supplied with hydraulic medium. Seals are disposed in grooves in the ribs and the vanes, which seals are braced between the inside wall surface of the cylinder or the outside shell surface of the motor shaft and the respective groove base, so that the seals hydraulically separate the working chambers from one another. The outside shell surface of the motor shaft and the inside wall surface of the cylinder are designed with recesses, so that the prestress on the seals is neutralized in at least one installation position of the motor shaft. The rotary actuator can be used in a stabilizer bar of a motor vehicle suspension system.

  • Patent number: 5575502
    Abstract: A rotary actuator for a divided stabilizer on a vehicle axle is taught. The rotary actuator has a cylinder, the ends of which are closed to form a working space. Ribs run axially on the inside diameter of the cylinder. In addition, vanes from a motor shaft have the same axial extension within the cylinder as the ribs of the cylinder. The vanes of the motor shaft and the ribs of the cylinder divide the working space into individual work chambers. The rotary actuator can also have a first and a second hydraulic connection for two separate work chambers, with an additional hydraulic connection system between at least pairs of work chambers. The orientation of the connected work chambers is such that the work chambers corresponding to the first hydraulic connection alternate with those which are connected to the second hydraulic connection.

  • Patent number: 4852419
    Abstract: The control device for a motor-vehicle friction clutch incorporates an electric motor which drives an output member in a substantially translational motion through a motion conversion crank gear unit designed as a worm gearing. This axis of a worm of the crank gear unit and the resultant drive force exerted on the output member by the assigned worm gearwheel lie in a common plane normal to the axis of rotation of the worm gearwheel. A spring-type energy accumulator supports the drive motion of the electric motor in the release direction of the clutch and is tensioned in the engagement direction by the electric motor. In this way a comparatively small-sized electric motor can also be used for rapid release movements.

  • Patent number: 4734693
    Abstract: For controlling a central locking installation and/or theft alarm of a motor vehicle a switch lock installation is provided which comprises at least one lock with mechanical tumblers for the mechanical locking and unlocking of a door or a bonnet of the motor vehicle. The tumblers form a first key secret. The key which blocks the tumblers carries an electrically, magnetically or optically readable information carrier for a second, operationally variable key secret. A reading device detects the information of the second key secret in a position in which the mechanical tumblers of the lock are released. If the key is moved in the opening direction of the lock, a control circuit compares the information read by the reading device with an ideal information stored in a memory circuit and controls the central locking installation and/or theft alarm accordingly.
