Abstract
The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.
