摘要: A method, by a control device, to activate an active discharge circuit to discharge a capacitive energy storage of at least one electrical consumer of an on-board power supply for a motor vehicle. An energy source for the on-board power supply can be coupled to the on-board power supply and be disconnected from the on-board power supply by a switching device. The control device receives a signal (S) for activating the active discharge circuit, examines, after receiving the signal (S), if the energy source is disconnected from the on-board power supply according to at least one first criterion, and activates the active discharge circuit only upon satisfaction of a condition that the energy source has been disconnected from the on-board power supply according to the at least one first criterion.

摘要: A wheel suspension for a vehicle axle of a two-track vehicle, having a wheel carrier carrying a vehicle wheel, which is able to be articulated to a vehicle body via a multi-link assembly, which multi-link assembly has a trapezoidal link in the form of a four-point link with two connection points on the body side and two connection points on the wheel carrier side. The trapezoidal link connection points on the wheel carrier side are designed with a higher elastic longitudinal compliance, that is, softer, than the trapezoidal link connection points on the body side.

摘要: A system for a vehicle, which has a battery, a DC-DC converter, a DC-AC converter, an electric motor, and a switch. The battery is connected to the DC-DC converter and the DC-AC converter is connected to the electric motor. The switch is arranged between the DC-DC converter and the DC-AC converter, and the switch is designed, in a first switching state, to electrically connect the DC-DC converter and the DC-AC converter and to permit an exchange of electrical energy between the battery and the electric motor in order to carry out a traction process. The switch is designed, in a second switching state, to electrically isolate the DC-DC converter and the DC-AC converter, to connect the battery to an electrical charging station, and to permit an exchange of electrical energy between the battery and the electric charging station in order to carry out a charging process.

摘要: An electric machine comprising a rotor having a rotor body. The rotor body has multiple poles each carrying at least one rotor winding formed from multiple conductor loops. The poles extend in a radial direction of the rotor and the conductor loops pass through slots each formed between two adjacent poles. A support element extending in the radial direction is arranged in each of the slots between the rotor windings of the adjacent poles. The support element applies pressure to the conductor loops when the rotor rotates and/or heats up. A pressure distribution element extending at least in portions in the radial direction along the support element and the adjacent rotor winding is arranged between the support element and the rotor windings, which pressure distribution element distributes the pressure applied by the support element onto the adjacent rotor winding.

摘要: A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim well delimited on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt hole circle as well as a rim center connecting the rim well and the hub with one another. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material. The automobile rim is formed during the die casting with at least one air conveying element for conveying air in the axial direction with respect to a longitudinal center axis of the automobile rim relative to an imaginary plane perpendicular to the longitudinal center axis and/or at least one surface enlargement element extending in the circumferential direction along a circular line.

摘要: A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).
