20110248555 | WHEEL CARRIER OF A MOTOR VEHICLE - A wheel carrier for a motor vehicle in which the wheel carrier is typically manufactured from aluminum. The wheel carrier comprises a recess ( | 10-13-2011 |
20090312928 | METHOD FOR MONITORING A STARTING PROCESS OF A MOTOR VEHICLE - The invention relates to a method for monitoring a starting process of a motor vehicle, having a drive train, with a driving motor, a torque transfer system, and a transmission, a controller, and an actuator controlled by the controller for actuating the torque transfer system. If a starting observer detects that, despite a clear starting request, no starting occurs, appropriate measures supporting the starting of the motor vehicle are thereupon initiated. | 12-17-2009 |
20090291802 | PRESSURE MEDIUM-ACTUATED CONTROL DEVICE OF AN AUTOMATED STEP-BY-STEP VARIABLE SPEED TRANSMISSION - A pressure medium-actuated control device of an automated step-by-step variable speed transmission. The device having a control valve for controlling an actively engaged disconnectable type clutch which is disposed along a power flow path between a motor and a transmission input shaft, and a self-retaining valve located in the pressure supply of the clutch control valve for a rotational speed-dependent emergency actuation of the disconnectable type clutch. An electrical switch-off actuator is connected to the self-retaining valve such that the valve piston, of the self-retaining valve, can be moved into an idle position to lock the pressure supply of the clutch control valve in a powered state of the switch-off actuator, and into an operating position determined by the applied control pressures in the power-off state of the switch-off actuator. | 11-26-2009 |
20090057968 | Controllable Hydraulic Bearing - A controllable hydraulic bearing for damping vibrations in a defined frequency band is proposed, which includes an elastomeric body ( | 03-05-2009 |
