Abstract
A wheel includes a rim having a rim well and rim flanges, a hub, and at least three spoke elements. Each spoke element forms at least one spoke between the hub and the rim. The spoke elements are fastened to an inside of the rim in a form-closed manner or a form-closed and bonded manner. In the hub region, the spoke elements are supported on each other in a circumferential direction at abutting surfaces designed therefor. A method for producing the wheel is provided.
Claims20
A process for manufacturing a wheel made of fiber composite material, the process comprising the steps of:
- inserting spoke elements, which comprise one or more textile strands or layers of textile strands, which run parallel to the longitudinal axis of the spoke elements, into a mold;
- closing the mold, wherein spoke element ends remain exposed in a vicinity of a rim and are split into two portions, which are fitted into the mold of a rim well and wherein the closed mold forms the shape of the rim;
- braiding over of the closed mold for manufacturing the rim well;
- consolidating the spoke elements and rim;
- and
- releasing the wheel from the mold, wherein:
- in the step of closing the mold, wherein the spoke element ends remain exposed in a vicinity of the rim and are split into two portions, the ends of the spoke elements are placed directly abutting one another in the hub area in the mold in the circumferential direction;
- and
- in the step of braiding over of the closed mold for manufacturing the rim well the ends of the spoke elements are limited by two hub parts in the axial direction.
A process for manufacturing a wheel made of fiber composite material, the process comprising the steps of:
- providing a mold;
- inserting spoke elements, which comprise one or more textile strands or layers of textile strands, which run parallel to a longitudinal axis of the spoke elements, into the mold;
- closing the mold, wherein an end of each of the spoke elements remains exposed in an area of a rim and another end of each of the spoke elements abuts an adjacent another end of the spoke elements in a hub area of the mold in a circumferential direction of the mold, the end comprising a first end portion and a second end portion, the first end portion and the second end portion being fitted into the mold of a rim well, the mold forming a shape of the rim when the mold is in a closed state;
- braiding over of the mold when the mold is closed for manufacturing the rim well, the another end of each of the spoke elements being arranged between two hub parts in the axial direction;
- consolidating the spoke elements and the rim;
- and
- releasing the wheel from the mold.
A process for manufacturing a wheel made of fiber composite material, the process comprising the steps of:
- providing a mold;
- inserting spoke elements into the mold, each of the spoke elements comprising one or more textile strands or layers of textile strands extending parallel to a longitudinal axis of the spoke elements, each of the spoke elements comprising a first spoke element end and a second spoke element end;
- closing the mold after inserting the spoke elements into the mold, wherein the first spoke element end of each of the spoke elements is exposed in an area of a rim and the second spoke element end of each of the spoke elements is in contact with an adjacent second spoke element end in a hub area of the mold in a circumferential direction of the mold, the first spoke element end comprising a first end portion and a second end portion, the first end portion and the second end portion being fitted into the mold of a rim well, the mold forming a shape of the rim when the mold is in a closed state;
- forming the rim well after the mold is closed, the second spoke element end of each of the spoke elements being arranged between two hub parts in an axial direction of the mold;
- consolidating the spoke elements and the rim to form a wheel;
- and
- releasing the wheel from the mold.
