  • Publication number: 20230060296
    Abstract: A drive unit for an electric vehicle has at least one electric machine, a multi-speed transmission, and a distributor device. The rotor of each electric machine is connected to an associated input shaft of the multi-speed transmission. The multi-speed transmission is connected on the output side to the distributor device with different transmission ratios being selectable in the multi-speed transmission. In addition, a drive power introduced into the distributor device can be distributed to at least two outputs of the distributor device. In order to provide a compact drive unit for an electric vehicle with permanent all-wheel drive or selectable all-wheel drive, the distributor device can be used to provide a longitudinal distribution of the introduced drive power in that the outputs of the distributor device are each provided for coupling to a respective drive axle of the electric vehicle.

  • Patent number: 10848861
    Abstract: A loudspeaker assembly for a vehicle includes an enclosure arranged to be positioned outside of a passenger compartment of the vehicle adjacent a first vehicle body panel. The enclosure has a front side, a rear side, a top portion and a substantially enclosed bottom portion, where the top portion includes an outer wall structure. A loudspeaker is mounted in the enclosure and configured to generate an acoustic signal to be radiated into the passenger compartment through an opening in a second vehicle body panel. The enclosure may include a plurality of ribs extending between the loudspeaker and the outer wall structure. A barrier may be disposed within the top portion inward of the outer wall structure and substantially surrounding the loudspeaker. The ribs and the barrier damp high frequencies to reduce propagation of high-frequency noise toward the passenger compartment.
