Abstract
A reinforcement for a plastic tank for a motor vehicle may include an attachment apparatus or element for attaching an internal reinforcing element of the tank. The attachment apparatus or element for attaching the internal reinforcing element may include at least a first structure configured to at least partially clamp around a first external part of the internal reinforcing element, and at least a second structure configured to surround at least partially a second external part of the internal reinforcing element. An assembly may be obtained after attaching an internal reinforcing element to such a reinforcement and a tank may include this assembly.
Claims21
A reinforcement suitable for a plastic tank configured for a motor vehicle, the reinforcement comprising:
- an attachment apparatus configured for attaching to an internal reinforcing element of the plastic tank, the internal reinforcing element comprising a first end and a second end, both ends arranged to be welded directly on the plastic tank, the attachment apparatus comprising:
- a first structure configured to at least partially clamp, in an inward direction orthogonal to a weld surface of the internal reinforcing element on the plastic tank, around a first external part of the internal reinforcing element, and
- a second structure configured to at least partially surround a second external part of the internal reinforcing element,
- wherein the first structure is closer to the first end of the internal reinforcing element than the second structure and the second structure is closer to the second end of the internal reinforcing element than the first structure, and
- wherein the first structure has a first internal circumference that is larger than a second internal circumference of the second structure.
A reinforcement suitable for a plastic tank configured for a motor vehicle, the reinforcement comprising:
- an attachment apparatus configured for attaching to an internal reinforcing element of the plastic tank, the internal reinforcing element being configured to be welded directly at both ends to the plastic tank and having a longitudinal axis and radial axes perpendicular to the longitudinal axis, the attachment apparatus having a height that is parallel to the longitudinal axis and a width that is in a plane parallel to the radial axes, the attachment apparatus comprising:
- a first structure configured to at least partially clamp around a first external part of the internal reinforcing element, and
- a second structure configured to at least partially surround a second external part of the internal reinforcing element, wherein the first structure has a first internal circumference that is larger than a second internal circumference of the second structure,
- wherein the first structure is spaced from the second structure along the longitudinal axis, and
- wherein
- (i) the first structure at least partially encircles part of the first external part of the internal reinforcing element so as to be configured to exert a pressure radially inwardly, in a plane parallel to the radial axes, on the part of the first external part, and/or
- (ii) the second structure at least partially encircles part of the second external part of the internal reinforcing element so as to be configured to exert a pressure radially inwardly, in a plane parallel to the radial axes, on the part of the second external part.
