Abstract
An exhaust system with a multipiece heat shield for a work vehicle includes a first shield part and a second shield part. The first shield part surrounds an aftertreatment unit for aftertreating exhaust gases. The first shield part extends in an axial direction. The second shield part surrounds an exhaust tailpipe with radial spacing between the second shield part and the exhaust tailpipe. The second shield extends in the axial direction from the first shield part, wherein a radial gap between the first and second shield parts is sealed by a seal.
Claims16
An exhaust system with a multipiece heat shield for a work vehicle, comprising:
- a first shield part which surrounds an aftertreatment unit for aftertreating exhaust gases, the first shield part extending in an axial direction;
- and
- a second shield part which surrounds an exhaust tailpipe with radial spacing between the second shield part and the exhaust tailpipe, the second shield part extending in the axial direction from the first shield part, wherein a radial gap between the first and second shield parts is sealed by a seal;
- wherein the seal has a movable sealing lip which delimits an axial seal opening for receiving the second shield part, wherein in a starting position of the seal, the seal opening is smaller than a cross-section of an outer wall of the second shield part, and in a sealing position of the seal, the sealing lip lies against the outer wall of the second shield part.
