  • the web is, as already mentioned, spatially detached from the rim and also from the hub portion, that is, the web only connects the spokes to one another and is not formed as an extension or as a projection of the rim or of the hub portion.
  • An inventive web (also referred to as bridge) between at least two spokes, preferably between each arranged in the wheel and adjacent spoke, allows acoustic damping or decoupling.
  • the spokes act at certain brake excitations, especially when releasing the brake from a standstill, similar to a tuning fork, the spokes such a swing that creates an audible and unpleasant noise for the driver.

From an aerodynamic point of view, it is particularly expedient to cover an area of the spoke gap which is further spaced from the center of the wheel, since the highest losses in terms of air resistance occur in particular in the outer regions of the wheel. By such a cover, it is possible to reduce the air resistance and thus the energy consumption of the vehicle.

  • the spring ring is preferably connected to the spokes so that it supports the respective adjacent spokes against each other and thus stiffening and / or particularly preferably acts vibration damping.
