Embodiment Construction

[0046] attached figure 1 The flexible pipe 1 shown has a (partially cut-away) corrugated corrugated pipe 2 and a braided hose 3 encircling it, which acts on the bellows with a force of, for example, approximately 2N. friction. A buckle hose 4 is installed in the bellows 2. In the embodiment described, the buckle hose 4 is a spiral winding part 41 with a substantially S-shaped section. By means of this S-shaped section, the winding part 41 The adjacent elements of each are nested with each other (see attached image 3 to attach Figure 5 ). Alternatively, the buckle hose can consist of a plurality of arcuate sections corresponding to the cross-sectional form of the helical winding 41, by means of which the axially adjacent arcuate sections of the snap-in hose engage with each other (accompanying drawing not shown).

[0047] In order to reduce vibration, a spacer 5 (attached) is installed in the annular cavity between the bellows 2 and the buckle hose 4. Figure 8-15 ), th...

Abstract

The invention relates to a flexible pipe element (1), especially for exhaust pipes (9) pertaining to internal combustion engines for motor vehicles. Said pipe element comprises helical or annular convoluted bellows (2); at least one strip wound hose (4) which is coaxially adjacent to the bellows, and is coiled in a spiral-shaped manner or comprises a plurality of ring segments; at least one spacer (5) which is locally arranged between the bellows and the strip wound hose (4); and an externally arranged knitted hose (3). The inventive pipe element has an overall rigidity of 5 N / mm at the most.

Description

technical field [0001] The invention relates to a flexible pipe especially suitable for exhaust pipes of internal combustion engines of automobiles. Background technique [0002] Flexible pipes of this type generally have a helical or ring-shaped corrugated bellows and a helically wound or buckle hose with several segment segments adjoining the bellows coaxially, wherein the buckle The cross-section of the helical winding (Wicklung) or segment (Ringsegment) of the hose is substantially S-shaped, by means of which axially adjacent elements or axially adjacent elements of the helical winding of the snap-on hose Adjacent arcuate segments overlap each other. These elements are installed as plug-ins on the exhaust pipe of the car. The exhaust pipe is generally fixed on the chassis of the car, sometimes connected to a flexible support, which is used to withstand movement and vibration and exclude its onward transmission to adjacent objects, such as Vibrations of elastically supp...
