Exhaust gas cleaning device, exhaust system, removal method

摘要

The present invention relates to an exhaust gas cleaning device (2) of an exhaust system (1) of a combustion engine, more preferably of a motor vehicle, with a catalytic converter unit (3) having a catalytic converter support pipe (7) and at least one oxidation catalytic converter element (8) mounted in the catalytic converter support pipe (7), and with a particle filter unit (4) having a particle filter support pipe (11) and at least one particle filter element (12) mounted in the particle filter support pipe (11).;A simple handling with simple construction can be achieved with a receiving pipe (5) in which one of the support pipes (7, 11) is axially inserted, and with a clamp connection (6) which sets the receiving pipe (5), the catalytic converter support pipe (7) and the particle filter support pipe (11) against one another.

1. An exhaust gas cleaning device of an exhaust system of a combustion engine, comprising:
a catalytic converter unit having a catalytic converter support pipe defining an interior peripheral surface and at least one oxidation catalytic converter element mounted in the catalytic converter support pipe, a particle filter unit having a particle filter support pipe defining an interior peripheral surface, and at least one particle filter element mounted in the particle filter support pipe, a receiving pipe in which the catalytic converter support pipe is axially inserted, a clamp connection which sets the receiving pipe, the catalytic converter support pipe and the particle filter support pipe against one another; wherein the interior peripheral surface of each of the catalytic converter support pipe and the particle filter support pipe are at least partially in axial contact with one another; wherein the receiving pipe at a face end in the clamp connection comprises a circumferential receiving pipe collar standing away to the outside, the catalytic converter support pipe at a face end in the clamp connection comprises a circumferential catalytic converter support pipe collar standing away to the outside, and the particle filter support pipe at a face end in the clamp connection comprises a circumferential particle filter support pipe collar standing away to the outside; wherein the clamp connection comprises two clamping rings and a clamp axially clamping the two clamping rings towards each other; wherein one clamping ring is designed as a receiving pipe clamping ring, which axially abuts the receiving pipe collar on a side facing away from the catalytic converter support pipe collar, while the other clamping ring is designed as a support pipe clamping ring which axially abuts the particle filter support pipe collar on a side facing away from the catalytic converter support pipe collar.
