AI Technical Summary

Problems solved by technology

The combination of a sufficiently fast wheel rotation and a relatively strong and high-frequency wheel movement thus leads to accelerations or vibrations superimposed on the centripetal force, which lead to unnecessary cover movements
This is not only undesirable from a mechanical point of view, since this results in high mechanical loads for the swivel bearing and coupling bearing, but also creates acoustic disadvantages, since the continuous opening and closing causes noise
And it doesn't meet expectations visually.

Embodiment Construction

[0023] figure 1Shows a view of a part of a wheel 1 according to the invention including a rim 2 on which (not shown in detail here) a brake disc hub / brake hub is usually fastened or assigned in the assembled state. The rotor cover and the brake disc fixed on the brake disc hub. The rim 2 has a plurality of openings 3 for ventilation and appearance, for which in the example shown a sheet-like cover 4 is assigned in each case, wherein figure 1 Only one such cover 4 is shown in FIG. The cover 4 serves to close the corresponding opening 3 over a large area and to open it for ventilation if required.

[0024] To this end, the cover part 4 can be swiveled through a certain angle, for example 5° to 10°, about the pivot axis 5 . according to figure 1 and 2 The view in is related to the inside view of the rim 2. The swing mobility of each cover around the swing axis 5 is such that each cover 4 is figure 1 The right-centre outer corner 6 is angled towards the inside of the rim, t...

Abstract

A vehicle wheel includes a wheel rim on which is provided a plurality of plate-like covering elements, which are mounted so as to be pivotable about a pivot axis, for temporarily closing off associated apertures in the wheel rim, wherein each covering element can be displaced along the pivot axis under centrifugal force counter to the force of a restoring element and is connected to the wheel rim by means of a coupling element, which imparts positive guidance during a displacement movement, in such a way that the covering element can be pivoted between a radially inner open position and a radially outer closed position, wherein a pivot axis rod arranged on the outer side of the wheel rim is connected to the covering element via a hydraulic or pneumatic vibration damper.

Description

technical field [0001] The invention relates to a wheel comprising a rim on which a plurality of sheet-shaped cover elements pivotably supported about a pivot axis are provided for temporarily closing the relevant rim openings, wherein , each cover is movable under centrifugal force along the pivot axis against the force of the reset element, each cover is connected to the rim via a coupling element that is forcibly guided during the displacement movement in such a way that the cover can be moved in the It swings between a radially inner open position and a radially outer closed position. Background technique [0002] There are different requirements that are partially contradictory to each other in the design concept of modern rims. A central requirement, in addition to achieving a simple rim profile that is as simple as possible to produce, is to provide the rim with the highest possible air flow in order to be able to cool the brake disk optimally by the air flow if nece...
