摘要:
A method and apparatus for dynamically balancing a tire/wheel assembly of a motor vehicle is provided. The wheel of the tire/wheel assembly has raceways along the circumference of the wheel containing balancing media that provide dynamic rotational harmonic center of moment compensation for manufacturing imperfections. Balancing media may be solid bearings, fluid, or a combination thereof, and the balancing media moves along the raceways to certain areas of the wheel to compensate for the mass imbalances on the correspondingly opposing side of the wheel. The raceways have any combination of mathematically-described geometric cross-sectional area shapes, and the balancing media may be shaped accordingly. In another embodiment, the raceways may be noncontiguous and may have different orientations throughout the wheel. The present invention also provides sensors for real-time management of the balancing media to inform the driver of sudden changes in the state of the tire/wheel assembly.

A rim for a mountain bike is provided, including a rim body having a rim well, a rim base and two lateral rim flanks and a hollow space device with a hollow space. A width of the rim body is larger than 30 mm. The hollow space device of the rim body is radially outwardly limited by the rim well and laterally and radially inwardly, by an inner enclosing wall including the rim base and the rim flanks. The radially inwardly enclosing wall forms an internal wall that is substantially closed, apart from the nipple accommodations. The rim well includes a plurality of recesses having a surface proportion of at least 10% of a surface of the rim well.

The invention includes a rim for a cycle wheel, having a U-shaped radial cross section, with two lateral sidewalls and a bridge connecting the sidewalls and located so as to be opposite an axis rotation of the wheel. The sidewalls each define a planar braking surface, adapted to cooperate with a brake pad. The height of at least one braking surface, measured radially, is not constant over the circumference of the rim and has at least one variation in height.

A rim for a vehicle comprising a tire contact to which a clincher or a tubed tire may be fastened is disclosed. The tire contact includes a core wrapped by reinforcing thread so that the core is covered by a supporting layer formed by the reinforcing thread. The tire contact is covered at least on the radial inside by the cover layer formed of reinforcing thread so that a reinforcing ring is provided between the cover layer and the tire contact. Methods of manufacturing fiber composite rims are also disclosed. A core is wrapped with a reinforcing thread to deposit a supporting layer on the core and to form a tire contact. The tire contact is arranged adjacent an aerodynamics enhancing component and a reinforcing ring. The tire contact, the aerodynamics enhancing component and the reinforcing ring are wrapped with one or more reinforcing thread(s) to form a cover layer.
