  • Truck comprising a retaining system for the cab in case of a collision
    Patent number: 8007033
    Abstract: A truck has a driver's cab tiltably mounted above a drive train and coupled in an articulated fashion to a bottom chassis by a bearing. The drive train is attached to the chassis, and has a restraint system for the driver's cab. In the case of a head-on collision of the truck with an obstacle at the level of the driver's cab, the restraint system serves to absorb and deflect collision forces at the driver's cab. The restraint system includes a flexible coupling element that establishes a connection, which is resistant to tensile stress counter to the direction of travel, between the driver's cab and a front fixed part of the drive train located underneath it.

  • Press-hardened part and method for the production thereof
    Patent number: 7998289
    Abstract: To produce a metallic shaped part (1), in particular a vehicle body part, from a semifinished product (2) made of an unhardened hot-workable steel sheet, first of all the semifinished product (2) is formed by a cold-forming method, in particular a drawing method, into a part blank (10) (process step II). The part blank (10) is then trimmed at the margins to a marginal contour (12?) approximately corresponding to the part (1) to be produced (process step III). Finally, the trimmed part blank (17) is heated and press-hardened in a hot-forming tool (23) (process step IV). The part (1) produced in the process already has the desired marginal contour (24) after the hot forming, so that the final trimming of the part margin is dispensed with. In this way, the cycle times during the production of hardened parts of steel sheet can be considerably reduced.

  • Engine control system for torque management in a hybrid powertrain system
    Patent number: 8000866
    Abstract: An engine is coupled to an input member of a hybrid transmission, the hybrid transmission operative to transfer power between the engine and a second torque machine and an output member. A method for controlling the engine includes monitoring an operator torque request, commanding operation of the hybrid transmission in a continuously variable operating range state, determining engine commands comprising a first engine torque request and a second engine torque request based upon the operator torque request and the operation of the hybrid transmission, determining an engine torque constraint comprising a maximum engine torque based upon a capacity of the hybrid transmission to react the engine torque, and controlling engine operation based upon the first engine torque request only when the second engine torque request exceeds the engine torque constraint.

  • Steering column arrangement
    Patent number: 7992464
    Abstract: A steering column arrangement having a steering spindle (2) which is mounted in a casing tube (3, 5) so as to be rotationally movable, and having a switch module (7) which is held immovably with respect to the steering spindle (2). The switch module (7) is fixed radially and axially on the casing tube (3), the switch module (7) being supported on a bearing (12) which is arranged on the steering spindle. The Switch module comprises a centering device (8) which, under action of a force (F) which is oriented coaxially with respect to the longitudinal axis (L) of the steering spindle (2), fixes the switch module (7) on the casing tube (3).

  • Radiator Grill Arrangement
    Publication number: 20110187153
    Abstract: The invention relates to a radiator grill arrangement (10, 10?) for a motor vehicle front end of a motor vehicle, which comprises a plurality of air passage openings (16), which can be closed at least substantially by at least one flap element (20). In the embodiment according to the invention, the at least one flap element (20) is thereby supported so as to be able to swivel about an associated flap axis (24). In driving states of the motor vehicle in which little cooling air is needed for the engine or engine compartment, the entire flap arrangement or a part of the flaps (20) can thus be closed in order to improve the drag coefficient cw of the motor vehicle and to save fuel. Also in the parked state of the motor vehicle with the engine switched off, it is possible to close the flap arrangement in order to ensure a more aesthetically pleasing appearance of the motor vehicle.
