Abstract

PROBLEM TO BE SOLVED: To prevent stress concentration while ensuring the flexibility of the whole flexible tube for an exhaust pipe. SOLUTION: The flexible tube 10 has an inner tube 15 and an outer tube 16, cylindrical parts 11 for inserting the exhaust pipe 1 are formed in both end parts, and a section between both cylindrical parts is a bellows part 12 formed like bellows. A cover 3 surrounding them and made of a wire netting is connected with the exhaust pipe to form an exhaust pipe joint. The whole length of the flexible tube is divided into a central part A and end side parts B on both sides, and a reinforcing tube 17 is nipped between the inner tube and the outer tube in the end side parts B. Consequently, the end side part has a three layer structure, the rigidity is increased, stress is flattened, and fatigue strength is improved. Since the central part has two layers, high flexibility is kept, and the thermal insulation effect is obtained by an air layer.

ー３の網目を通して曝され、腐食し易い環境にある。The flexible tube 50 is intended to cut off vibration from the engine side by flexing flexibly while preventing exhaust leakage, and is formed in a bellows shape so as to be expandable and contractible. The cover 3 prevents the flexible tube from being damaged by foreign matter. However, since the exhaust gas flows through the inside of the flexible tube 50, the flexible tube 50 is exposed to a high temperature, and is exposed to salt as a snow removing agent sprayed on the road through the mesh of the cover 3, so that the flexible tube 50 is in an environment that is easily corroded.

Therefore, in order to reduce the cost and further increase the flexibility, the flexible tube 50 is connected to the inner tube 52 and the outer tube. Tube 53
Has been performed. In the drawing, the inner tube 52 and the outer tube 53 are shown separated from each other for easy understanding of the structure.

部位の疲労強度が低下するという問題がある。When such a flexible tube 50 is attached to an exhaust pipe and receives a shearing load while the vehicle is running, it deforms as shown in FIG. 6 (a). That is, the flexible tube 5
Although the amount of deformation in the central portion A of 0 is small, the amount of deformation in the vicinity B at both ends is large. For this reason, as shown in (b), there is a problem that stress concentration occurs at both end portions of the flexible tube 50, and the fatigue strength of the portion is reduced.

有する。As described above, according to the present invention, in a stretchable flexible tube formed by stacking at least two layers of tubes in a bellows shape, a reinforcing member for increasing rigidity at both ends with respect to a center portion is provided. Since it is provided between the two layers of pipes, the rigidity at the end where stress tends to concentrate is increased, and the stress is flattened. This has the effect that the fatigue strength is improved by the minimum necessary reinforcing members while securing the flexibility of the flexible tube as a whole while leaving the central portion in two layers.

In this case, the rigidity of the end where the stress tends to concentrate is increased, and the stress is flattened. Further, the central portion secures flexibility by dense small holes, and a heat insulating effect is obtained by the air layer of the small holes.
