An axle drive device for a motor vehicle, having at least one drive assembly that is in operative connection with an input shaft of a shift transmission connecting the drive assembly to a wheel axle. The shift transmission a multiple-speed draw key transmission, having a draw key that, in different positions, establishes different transmission ratios between the input shaft and an output shaft of the shift transmission, wherein the draw key is connected to a centrifugal force regulator that shifts the draw key in dependence on a rotational speed of the input shaft or a rotational speed of the output shaft.

A drive device for a motor vehicle, with a first drive assembly, a second drive assembly, and an auxiliary drive having at least one auxiliary assembly. The auxiliary drive being coupled to or can be coupled to, respectively, the first drive assembly and the second drive assembly via an epicyclic gear transmission. The auxiliary drive is coupled to a first transmission element of the epicyclic gear transmission. In this case, a second transmission element of the epicyclic gear transmission is coupled by a gearshift transmission, which is shifted in a speed-dependent manner, to a secondary drive shaft, which is coupled to or can be coupled to the first drive assembly.

A drive device for a motor vehicle. A first drive assembly, a second drive assembly, and an epicyclic gear train, via which the first drive assembly and the second drive assembly can be coupled to each other and to a driven shaft of the drive device. The first drive assembly is coupled to a first transmission element, the second drive assembly is coupled to a second transmission element, and the driven shaft is coupled to a third transmission element of the epicyclic gear train. The epicyclic gear train has a locking clutch for coupling of the second transmission element and the third transmission element to each other and the first transmission element can be braked by means of a braking device.

A drive device for a motor vehicle, comprising a first drive assembly, a second drive assembly, and an epicyclic gear train coupled to the second drive assembly, wherein the second drive assembly can be coupled to a driven shaft of the drive device via the epicyclic gear train and to the first drive assembly by means of a shift clutch. It is hereby provided that a secondary drive shaft of an at least one secondary drive of the drive device having a secondary assembly is coupled to the epicyclic gear train. The invention further relates to a method for operating a drive device for a motor vehicle.

An exhaust system for a motor vehicle, with an exhaust pipe for discharging exhaust of a device that produces an exhaust. A heat accumulator, which surrounds the exhaust pipe in the peripheral direction with respect to a longitudinal central axis of the exhaust pipe, is present, at least in regions thereof, and, in the radial direction between the exhaust pipe and the heat accumulator over at least a portion of the longitudinal extension the heat accumulator, a cross-section adjusting element for adjusting a passage cross section is arranged between the exhaust pipe and the heat accumulator. The cross-section adjusting element has a first holed pipe, which surrounds the exhaust pipe, and a second holed pipe, which surrounds the first holed pipe. The first holed pipe and the second holed pipe can be shifted in position relative to each other for adjusting the passage cross section.
