摘要:
The invention relates to a method for producing a wheel rim, having a rim base, from a fibre composite. The problem to be solved by the invention is that of improving the production of the wheel rim, and especially to ensure a reliably functioning wheel structure which can be achieved with little financial and technical outlay. The problem is solved in that during the production of the rim base (2) a connection element (3, 13, 21, 31, 42, 51) is joined to the rim base (2), said connection element (3, 13, 21, 31, 42, 51) being designed and arranged in such a way that a wheel disk (4, 14, 22, 36, 45) can be connected to said connection element (3, 13, 21, 31, 42, 51).
摘要:
A rim and a method for manufacturing a rim (1) for a motor vehicle which provide the steps of manufacturing a central assembly (3) at least partially by means of a press moulding process, known as SMC (Sheet Moulding Compounds), using a carbon fiber material with short fibers, preferably carbon fibers having a length up to 25-50 mm, and a resin, preferably of the thermosetting type; manufacturing the outer channel (2) and assembling the outer channel (2) and the central assembly (3) so as to obtain the rim (1).
摘要:
The invention relates to a monolithic wheel which is made of fiber composites having uninterrupted fibers, has excellent mechanical properties, and is lightweight, as well as to a method for the production thereof. Said wheel particularly comprises a rim base and a wheel disk that extends to a rim flange of the rim base. The wheel disk is formed at least in part by layers of fibers which extend from the rim base over a rim flange and the wheel disk. The wheel is produced using a multipart mold comprising parts that can be moved at least in the axial direction. Once the fibers have been put in place, the mold is entirely removed or remains in the wheel as a lost core.

A method for making a carbon fiber wheel rim includes: preparing an outer supporting piece (20); winding a carbon-fiber yarn (30) around the outer supporting piece (20) to form carbon fiber layers and to constitute an engaging seat preform (31); connecting an inner supporting piece (40) to the engaging seat preform (31); connecting a reinforcement piece (50) to the inner supporting piece (40); winding a carbon-fiber yarn (32) around an assembly of the engaging seat preform (31), the inner supporting piece (40) and the reinforcement piece (50) to form carbon fiber layers; fixing the assembly with the carbon fiber layers to form an outer frame preform (33); and cutting the outer frame preform (33) and the engaging seat preform (31) to form a trench (23) and removing the outer supporting piece (20) therefrom.
