Abstract
A wheel with a rim as well as a wheel spider, where the wheel spider has a hub and spokes. The wheel includes spokes including one or more linearly stretched textile strands as reinforcement material of a fiber composite and each linearly stretched textile strand runs at least once from the rim to the hub and back without interruption and thus forms at least one spoke. The textile strands are connected in a positive-locking manner and/or in substance with the hub and the rim. A process is provided for the manufacture of the wheel.
Claims9
A process for manufacture of a wheel with a wheel spider, whose spokes comprise one or more linearly stretched textile strands as reinforcement material of a fiber composite, the process comprising:
- preparing a mold corresponding to a rim contour having a first mold part and a second mold part, which has recesses for forming the wheel spider;
- preparing unconsolidated linearly stretched textile strands;
- inserting a first wheel hub part into the first mold part, such that a continuous course of a shape of spoke segments is imaged;
- inserting the unconsolidated linearly stretched textile strands into the first mold part, such that at least ends of the linearly stretched textile strands are integrated into the first mold part in an undercut area and the linearly stretched textile strands extend through the hub;
- inserting the second hub part;
- closing the mold by joining the first mold part and the second mold part together;
- forming a reinforcement fiber structure of the rim by means of further deposition of fibers onto the mold;
- joint consolidating the rim and the wheel spider;
- removing the wheel from the mold.

- inserting a first wheel hub part into the first mold part, such that a continuous course of a shape of spoke segments is imaged;
- inserting already consolidated or pre-consolidated linearly stretched textile strands into the first mold part, such that at least ends of the linearly stretched textile strands are integrated into the first mold part in an undercut area and the linearly stretched textile strands extend through the hub;
- inserting the second hub part;

A process for manufacture of a wheel with a wheel spider, the process comprising:
- providing a rim;
- forming a wheel spider having a hub and spokes, said spokes comprising one or more textile strands as reinforcement material of a fiber composite and each of said one or more textile strands extending at least once from said rim to said hub and back without interruption to form at least one of said spokes, said one or more textile strands having ends, which diverge from each other and are spread apart from each other;
- fastening said one or more textile strands to one of said rim and a well of the wheel via a positive-lock connection, said positive-lock connection comprising one of at least a portion of said rim and at least a portion of said well.
