  • Publication number: 20200393021
    Abstract: An electric drive for a motor vehicle includes a housing, an output shaft, an electric engine, which has a stator and a rotor rotatable relative to the stator, a planetary gear set arranged in the housing, which has a sun gear, a ring gear and a planetary carrier, which is non-rotatably connected to the output shaft, having a first switching element, by means of which the ring gear can be non-rotatably coupled to the rotor, and a second switching element, by means of which the ring gear can be non-rotatably coupled to the housing. The first switching element and the second switching element are coupled to each other via a first coupling element and thereby can be operated together by a single first actuator common to the first switching element and the second switching element.

  • Patent number: 7481128
    Abstract: In a gearshift unit for a transmission of a motor vehicle, wherein a driver of the motor vehicle shift the gears of the transmission by means of a gearshift lever and the gearshift unit has a gearshift power-assist unit to enhance the shift force exerted by the driver of the vehicle, a control device is provided which detects a significant increase in a moment of inertia, in excess of a normal amount, of masses to be accelerated in the event of a gearshift in the transmission and actuates the gearshift power assist unit to assist the shift forces only when no significant increase in the moment of inertia has been detected in order to prevent high shifting forces from being generated when they might lead to damage to the transmission.

  • Publication number: 20060255518
    Abstract: The invention relates to a bearing structure for the damped transmission of impact and/or vibratory forces, in particular for buildings which are subjected to a seismic load, comprising a volume-elastic damping material which is arranged between two parts of a bearing body. According to the invention the first bearing part has essentially the shape of a pot, with a guide sleeve being arranged in the centre of the pot and one or several reinforcing sleeves being arranged between the guide sleeve and the pot inner wall and the damping material filling the spaces between the pot inner wall, reinforcing and guide sleeves at least partially. A second bearing part comprises a bolt which can be displaced inside the guide sleeve, with the bolt being connected with a first fastening plate. A second fastening plate is provided on the outside of the pot in order to anchor the bearing parts at the building.

  • Patent number: 6366679
    Abstract: A method wherein an auralization is performed, in that a plurality of spatial pulse responses are incited from various locations in the same room, and are received via a multi-channel receiving apparatus, for example, a directional microphone or a plurality of directional microphones at one location, and are recorded. For the reproduction, a multi-channel loudspeaker arrangement of vertically configured loudspeakers and of horizontally configured loudspeakers is used, at least two loudspeakers being required to reproduce sources in one line from point to point that are able to be localized, at least three loudspeakers for reproduction in one plane, and at least four loudspeakers in one room.

  • Patent number: 4618987
    Abstract: The invention relates to acoustically radiating randomly large rooms and surfaces according to propagation time principles, whereby action or representation and reception or listening areas border directly on one another or are identical. Its object is to avoid error locations and skipping effects caused by movements, which are especially interfering for important solo sound sources. The resulting object of realizing a propagation time staggering without limiting source areas, and responding to the acoustic capacity of the sources, is solved by means of a control device connected to the delay or amplification devices, and which differentiatedly controls them analogous to the sound paths between the source and the acoustic radiator locations.
