Description

TECHNICAL AREA

The invention relates to an arrangement for mounting a hollow round tube to a fender according to the preamble of claim 1. The invention also relates to a vehicle with such an arrangement.

STATE OF THE ART

Vehicles such as trucks are equipped with fenders. A common way of mounting the mudguard to the vehicle is with a tube secured transversely along the mudguard and chassis / vehicle to an end portion protruding from the mudguard.

When attaching a round pipe to the mudguard with screw connections, a plate must be screwed to a round pipe. Here, the contact between the plate and the tube is a line rather than a desired surface, which leads to unpredictable behavior in the screw connection and can also deform the tube. It is possible to add a circular insert to the tube to avoid deformation; but the large margin in the manufacturing tolerances of the pipe makes it difficult to construct the insert.

US 4,377,294 discloses an assembly for mounting a support bar to a fender. The assembly includes pairs of clamping plates disposed on opposite sides of an inner wall of the carrier bar. A plurality of clamping screws are disposed along the elongated clamping plates and the heads of the screws are fixed to this clamping plate inserted with the interior of the tube. The plates have substantially the same curvature to effectively mate with each other in contact engagement with the surfaces of the respective components.

However, there is a need to improve arrangements for mounting a hollow round tube to a fender.

OBJECTS OF THE INVENTION

An object of the present invention is to provide an arrangement for mounting a hollow round tube to a mudguard which effectively avoids deformation of the tube without requiring high tolerances.

The elongated member has a cross-sectional shape to provide at least two inner contact contact surface portions, and the outer member has a cross-sectional shape for providing at least two outer contact contact surface portions corresponding to at least two inner contact contact surface portions.

The elongated member has a cross-sectional shape for providing at least two contact surface portions for internal contact with corresponding inner surface portions of the tube.

Thereby, a simple and effective assembly is ensured without affecting the pipe to a greater extent, by effectively achieving the opposing forces by arranging at least one nut section in the elongated element.

According to one embodiment of the arrangement, the outer element is designed to provide a curved section with a curvature adapted to the pipe diameter to provide two contact surface sections for external contact on different sides of the screw connection. By providing a curved portion having a pipe diameter-adapted curvature for providing two outer surface contact surface portions on different sides of the screw joint, two contact surface portions can be effectively and easily provided without requiring high tolerances. According to one embodiment, the curved portion has an arcuate shape with a diameter smaller than the outer diameter of the tube.

According to one embodiment of the arrangement, the arrangement comprises at least two screw connections along the tube for the outer element and the elongate element. As a result, an efficient assembly is achieved, which facilitates a stable support of the fender.
