Problems solved by technology

Otherwise, the introduction of smaller forces in specific areas of the clamp, for example on the side of the clamping band relative to the clamping device, may result in reduced sealing or leakage
Furthermore, an uneven clamping force can lead to overloading of the object to be clamped, which can lead to the formation of cracks or cracks and can significantly reduce the service life of the connection

Embodiment Construction

[0034] figure 1 The shown hose clamp 1 is a worm drive clamp comprising a clamping band 2 and a clamping device 3, a concave receiving area 5 extending in a circumferential direction, said concave receiving area 5 is arranged in said On an inner surface 4 of the clamping band 2 , said accommodation area is mirrored in a corresponding raised expansion 7 on an outer surface 6 of said clamping band 2 . Below the clamping device 3 the receiving area 5 is interrupted and the inner surface 4 of the clamping band 2 is configured to be smooth at this point.

[0035] Two axial edge areas 8 , 9 are arranged on the edge of the clamping band 2 , which axially delimit the receiving area 5 and serve essentially to transmit forces to a Hose ends or similar.

[0036] The receiving area has a first end area 10 and a second end area 11, between which the clamping device 3 is arranged. The first end region 10 tapers towards a first end 12 and the second end region 11 tapers towards a second e...

Abstract

A hose clip includes a clip band and a clamping device. A receiving region is configured between axial edge regions of the clip band. The receiving region extends radially outwardly and in the circumferential direction. The receiving region is interrupted in the region of the clamping device.

Description

technical field [0001] The present invention relates to a hose clamp as described in the Summary of the Invention below. Background technique [0002] Multiple hose clamps have a wide range of possible uses that can be utilized commercially. A particularly common field of use in this context is the fastening of fluid lines to pipe connectors, for example in motor vehicles. [0003] Due to a number of factors, namely higher system pressures, higher temperatures, and longer periods of use, the need for multiple connections in fluid lines continues to increase. In this case, in particular, high clamping forces and effective sealing properties are required. [0004] Prior art hose clamps typically have a smooth clamp band with ends of the clamp band connected together by a clamping device. By means of the clamping device, a diameter of the hose clamp can be reduced. Thus, radial clamping forces and / or compressive forces are applied, for example, onto a hose end, which is pus...
