An electric drive for an electric or hybrid vehicle has an electric motor, with which a vehicle wheel is drivable, for instance via an articulated shaft. The the electric drive is embodied additionally with a mechanically actuatable wheel brake, which is actuatable by the electric motor selectively for driving the vehicle wheel via a shiftable distributor gear. The invention has the advantage that the electric motor provided for driving the vehicle wheel is simultaneously used for actuating the wheel brake (24) as well.

An accumulator for passenger cars or commercial vehicles, including a device for storing electric energy, two electric connecting devices, in particular connecting contacts, for electrically connecting the device for storing electric energy to an electric drive motor, provides a financial incentive for the user for moderate handling of the accumulator. Such a task is achieved in that at least one sensor is configured for detecting measurement data in regard to the electric current and/or the electric voltage of the accumulator taken from and/or fed to the accumulator and/or the temperature of the accumulator and/or the installation time and/or the electric current time of the accumulator.

The invention relates to a method for controlling the withdrawal of gas from a sorption reservoir. The temperature in the sorption reservoir having a decreasing amount of gas therein is increased until a maximum acceptable temperature is reached such that a predetermined minimum pressure in the sorption reservoir does not fall below that threshold. The invention also relates to a device for storing at least one gas, having a sorption reservoir that has at least one attachment via which the sorption reservoir can be filled with gas or via which gas can be withdrawn from the sorption reservoir. The invention also relates to a device having at least one heating element which can warm the sorption reservoir, also a control system that can increase the temperature in the sorption reservoir when withdrawing the gas in such a manner that a predetermined minimum temperature in the sorption reservoir is not fallen below in order to attain a maximum acceptable pressure.
摘要:
The fuel reformer, especially for a fuel cell, produces a hydrogen-containing reformate from a fuel or hydrocarbon mixture supplied to it by partial oxidation (POX) and/or an autothermal reforming process. The reformer provides improved local reaction temperatures with increased conversion of hydrocarbons to hydrogen, decreased residual carbon monoxide formation and at the same time an increased yield of hydrogen. A gas supply member for distribution of reactants, such as air and/or oxygen, is arranged within the flow path of the fuel or hydrocarbon mixture in the reformer. The gas supply member has a plurality of gas supply outlets distributed in a flow direction along the fuel flow path for supplying the reactants to a catalyst material, which are distributed and formed so that reaction regions are more uniformly distributed along the flow path.
摘要:
A device and method for determining a roadway gradient quantity, which describes the gradient of a roadway on which a vehicle is situated, is described. The device includes a liquid container, which is mounted to the vehicle and contains a liquid, at least one pressure sensor, which is mounted in the bottom of the liquid container and is used to ascertain a pressure quantity which describes the hydrostatic pressure in the liquid container, and an evaluation unit to which the pressure sensor is connected. In the evaluation unit, the roadway gradient quantity is determined as a function of the pressure quantity.
摘要:
An apparatus for stabilizing a vehicle combination made up of a tractor vehicle and a trailer or semitrailer. For this purpose, the apparatus contains a first determination arrangement used to determine an inflection angle variable that describes the angle between the longitudinal axis of the tractor vehicle and the longitudinal axis of the trailer or semitrailer. The apparatus also contains a processing arrangement with which a comparison is performed as a function of the inflection angle variable and a comparison variable. The apparatus contains a first actuator arrangement associated with the trailer or semitrailer and with which a brake pressure can be established at at least one wheel of the trailer or semitrailer. The first actuator arrangement is actuated at least as a function of the comparison performed with the processing arrangement. The apparatus furthermore contains a second determination arrangement with which the comparison variable is determined as a function of the velocity of the tractor vehicle and/or as a function of whether stability interventions are being performed for the tractor vehicle.
