An electric vehicle, having a floor assembly including lateral longitudinal carriers, front and rear crossmembers, a vehicle undertray which extends between the lateral longitudinal carriers and the crossmembers and a passenger compartment floor which extends above the vehicle undertray, a technical space between the passenger compartment floor and the vehicle undertray in a rear section of the floor assembly, in which rear section rear seats are mounted above the passenger compartment floor. Furthermore, the electric vehicle includes at least one electric machine and a traction battery arranged below the floor assembly and on the floor assembly. Starting from the passenger compartment floor, the rear crossmember extends as far as into the region of the vehicle undertray and closes the technical space at a rear end. The traction battery is mounted on the lateral longitudinal carriers and on the front and rear crossmembers, and is sealed circumferentially.

Electric vehicle

A system includes a compressor and a mounting apparatus for mounting the compressor. The compressor is held exclusively by way of the mounting apparatus. The mounting apparatus includes two pendulum-type bearings and a hinged support.

A drive arrangement for auxiliary units in a motor vehicle has a control unit and an electric drive unit that is connected via a transmission arrangement to at least one auxiliary unit. An electric drive unit () is connected in terms of drive to at least two auxiliary units () by drive trains () of a transmission arrangement (). Clutch members () for coupling or decoupling the auxiliary units () in terms of drive are provided in the respective drive trains ().

Drive arrangement for auxiliary units in the motor vehicle sector

An assembly securing arrangement, in particular for securing a transmission in a motor vehicle body, includes an assembly support and at least one assembly bearing for the vibration-damped mounting of an assembly, wherein the at least one assembly bearing is a load-bearing component of the assembly support.

Assembly securing arrangement

A drive unit in a motor vehicle is mounted with two elastic motor mounts, of which each in each case couples an engine support, connected rigidly to the drive unit, elastically to a body structure of the motor vehicle, and with a torque support which is arranged above the two motor mounts transversely with respect to the vehicle longitudinal axis and which is coupled at one end to the drive unit and is coupled at another end to the body structure and is configured such that the two ends are connected, damped elastically, to one another. There is also provided a damping support arranged at a lower level than the torque support transversely with respect to the vehicle longitudinal axis and which is coupled at one end to the drive unit and is coupled at another end to the body structure. The damping support is configured such that transverse vibrations of the drive unit are damped.

A vibration adjustment of a drive assembly is achieved by way of a pivoted mount about a longitudinal vehicle axis of an articulated column. An exhaust system with exhaust mufflers and catalytic converters is used to shift a total powertrain vibration to a lower engine speed, and a significantly improved vibrational behavior can be achieved at idle speed.

A disk brake includes a brake disk which is surrounded by a caliper carrying lining devices. On the side of the lining device facing a brake lining surface, the brake disk has a concave brake disk surface. In order to at least partially reduce the noise emitted occurring during slow-down braking, the concavity of the brake disk surface and the convexity of the brake lining surface are constructed such that a noise-reducing form closure occurs.
