摘要:
An arrangement for transmitting data and/or signals between a transmission control device (1) and a plurality of actuator control devices (2A, 2B, 2C) for the local control of actuation movement of actuating shifting units. The transmission control device (1) and the actuator control devices (2A, 2B, 2C) are disposed such that they are movable relative to one another. At least one wireless communication transmission unit is provided, at least in sections, between the transmission control device (1) and the actuator control devices (2A, 2B, 2C).

A motor vehicle, with a drive train comprising a drive assembly, a transmission and wheels (2). The drive train further including actuators (3, 4) for adjusting at least one of the tracking and/or the camber. Sensors (5), for determining the tracking and/or camber, are integrated in the motor vehicle, and a control unit (6) only operates the actuators (3, 4), to adjust the tracking and/or the camber, when the drive train is in a defined actual static condition.

A method for power optimization in a vehicle/train, using time reserves which are included when planning a schedule, is proposed. In order to achieve a power-saving travel mode with the aid of an optimization algorithm, the presence of a number of completely or partially autonomous drive systems is taken into account, the separate functions of efficiency or power loss of each drive system being taken into consideration.

A stator for an electric motor consisting at least of a stator core (1) with grooves (2) and splines (3) and with a winding which, in turn, consists of a plurality of part-windings. The part-windings are fitted in the grooves (2) and each part-winding consists of a plurality of first and second coil groups (6, 7) having different shapes. For a part-winding, the first coil group (6) is connected in alternation to a second coil group (7) by way of their electric connection ends (16).
摘要:
A method for power optimization in a vehicle/train is proposed, using time reserves which are included when planning a schedule, an overall route to be traveled between a starting stop and a destination stop being subdivided into a number of steps. In order to achieve a power-saving travel mode, with the aid of an optimization algorithm, the kinetic energy of the vehicle and the time are used as state variables in a vehicle model. The changes in the state variables are considered with respect to the distance in each step.
摘要:
A device having an adjusting drive and a transfer element. The adjusting drive includes a stator and a rotor. The transfer element converts rotational motion to translational motion. The stator is axially longer than the rotor which axially slides within the stator. The difference in length approximately corresponds to the extent of desired axial movement of the rotor. Thus the rotor is provided with a constant electromagnetic torque over the length of axial movement of the rotor. The transfer element, located within the rotor, has a nut/screw connection, which converts torque into an axial adjusting force. A gap, between the stator and rotor, has a size relating to the desired electromagnetic properties of the motor and acts as a bearing during axial movement of the rotor, thus reducing the number of parts needed for the device parts, the amount of wear and favorable production costs when compared with conventional solutions.
摘要:
A switching system, preferably for use in the power supply of motor vehicles, and having one chargeable energy memory of a specific voltage level and consumers situated in the circuit of the energy memory is further developed so that a significant power load is thoroughly prevented even in the case of a high momentary power requirement of the electric consumers. The energy memory is designed for this purpose as power-limiting primary memory (1) to ensure the operation of a first group of consumers (2). The switching system further has a secondary energy memory (4) chargeable proceeding from the primary energy memory (1) which makes energy available to a second group of consumers (5) so that during energy delivery from the secondary energy memory (4) to the consumers (5) of the second group a feedback to the primary energy memory (1) is thoroughly prevented even during loading of the same by consumers (2) of the first group.
摘要:
A drive unit (1) with a steering motor and a propulsion motor, a first (2) of the two motors having a hollow drive shaft (5) through which a drive shaft (14) of a second motor (10) passes. Winding heads (7) of the first motor are positioned radially inside winding heads (15) of the second motor and overlap with them in axial direction, to save structural space in the axial direction. A stator (11) of the second motor is not solid but hollow with a port or bell shape. A rotor (12) of the second motor is in contact with the associated drive shaft not over its entire axial length, but only at a first end (13) which forms the bottom of the pot. This design forms a hollow space in which elements of the first motor can be accommodated at least partially. Parts of the two electric motors (2, 10) overlap in axial direction, where further axial structural space is advantageously saved.
摘要:
A method is proposed for power optimization in a vehicle/train, using time reserves which are included when a schedule is planned, an overall route to be covered between a starting stop and a destination stop being subdivided into a number of sections and each section being assigned a specific time reserve. In order to achieve a power-saving travel mode with the aid of an optimization algorithm, in each case only a limited route area, comprising a predefined number of sections, is taken into consideration for the optimization. The results of the optimization are implemented only for the first section of the route area. The optimization calculation is repeated cyclically during the journey of the vehicle/train, the route area being considered being moved together with the vehicle.
