The invention relates to a wheel, especially for motor vehicles, comprising a wheel rim and a wheel disc, the wheel rim having a rim base made of fiber composite material. The invention is characterized in that the wheel disc () can be indirectly connected to the wheel rim (), in particular the rim base (), by means of a connecting element () which is designed and associated with the rim base () in such a way that the connected wheel disc () is not in contact with the rim base ().

Wheel comprising a wheel rim and a wheel disc

A vehicle wheel comprising a wheel rim with a rim base made from fiber composite material and a wheel disc. The wheel disc is connected to the wheel rim by a connecting element which is guided through a passage of the rim base and is received in the wheel disc. The wheel rim comprises a connecting arrangement with at least one connecting element and a seal element which covers in a complete and hollow manner a part of one or more adjacent connecting arrangements that extends across the rim outer side of the rim base. A circumferential edge of the seal element is glued in air-tight manner to the rim well. Alternatively, the wheel rim comprises a connecting arrangement with a connecting element and a flexible sealing layer made from plastic and completely covers, by coating, a part of the connecting arrangement which extends over the rim outer side of the rim base. An edge region of the flexible seal layer is connected in an air-tight manner to the rim base.

Vehicle wheel having a connection of a wheel rim with rim base made from fiber composite material and a wheel disc

Disclosed is a vehicle wheel having a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc is connected to the wheel rim by a connecting element which is guided through a through-hole of the rim base and inserted in the wheel disc. The through-hole is arranged in the tire seat of the rim base and the connecting element is joined substantially in the direction of the radial extension of the wheel disc which is associated to the tire seat on the inner side of the rim. In the method for producing the wheel the connection between wheel rim and wheel disc is produced in the region of the tire seat of the rim base, and, after the insertion of the connecting element into the wheel disc, a portion of the connecting element protruding the contour of the outer side of the rim of the tire seat is shaped so that the connecting element conforms to the contour of the outer side of the rim of the tire seat.

Vehicle wheel having a connection between a wheel rim and a wheel disc and method for the production thereof

The invention relates to a spring () comprising at least one tensile body () that can be subjected to tensile stress and/or at least one compressive body () that can be subjected to compressive stress, the spring also comprising a force-displacement conversion unit () for converting the force-displacement of the spring force F, said force-displacement conversion unit () having a moveable input control element (), to which the spring force can be applied and a moveable output control element () which is operatively connected to the tensile body () or to the compressive body () in such a way that the spring force F produces a tensile stress in the tensile body () or a compressive stress in the compressive body () in a specific force-displacement conversion ratio.

The invention relates to a device for producing a component made from a fiber composite material from a semi-finished fibrous product by means of a multi-part molding and infiltration tool with tool parts, the molding functional surfaces thereof forming, when the tool is closed, a cavity that defines the component. The device is characterized in that the tool () has a sealing frame () which is designed as a hollow body and in which the semi-finished fibrous product () can be arranged, and the tool parts () are configured and can be associated with the sealing frame () such that, when the tool () is closed, the tool parts () are connected tightly to the sealing frame ().

Device for producing a component from fiber composite material

The invention relates to a vehicle wheel comprising a wheel rim, a wheel disc and at least one connecting element that connects the wheel disc and the wheel rim, wherein the connecting element is guided through a through-hole of the wheel rim and is joined in a joining channel of the wheel disc. According to the invention, an elongated sleeve () is provided that surrounds the connecting element () coaxially, which sleeve is designed and arranged in such a way that at least part of said sleeve interlockingly extends into a corresponding recess () of the wheel rim () and into a corresponding recess () of the wheel disc ().

The invention relates to a method and a device for infiltrating a fiber preform of a component of fiber composite material with a matrix material. On the method side, it is proposed that an elastic coating () is applied onto the fiber preform (), wherein the elastic coating () is widened to form a gap space () between the fiber preform () and the coating (). The matrix material () is then fed into the gap space () and the elastic coating () is subsequently pressed against the fiber preform (). On the device side, it is claimed that an elastic coating () is arranged on the fiber preform () and means are provided, which are in operative connection with the elastic coating (), by which the coating () can be widened while forming a gap space () between the fiber preform () and the coating (). A matrix material () can be fed into the gap space () and the coating () can be pressed against the fiber preform ().

Device and method for infiltrating a fiber preform

The invention relates to a method for producing a wheel rim having a rim base of a fiber composite material. 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 () a connection element () is joined to the rim base (), said connection element () being designed and arranged in such a way that a wheel disc () can be connected to said connection element ().

Method for producing a wheel rim with a rim base of fiber composite material

The invention relates to a wheel rim having a rim base () of fiber composite material and a wheel disk () connected to the rim base () in a radial marginal section. The radial marginal section of the wheel disk () comprises at least two partial layers () on each of which a contoured joining zone () which extends substantially axially is formed, the joining zone being flat connected to the rim base ().

Wheel rim with a rim base made of fiber composite material and method of manufacture

Disclosed is a method for producing a vehicle wheel with a connection between a wheel rim and a wheel disc in which the wheel disc is connected to the wheel rim by means of at least one connecting element that is guided through a through-hole of the rim base and is joined in the wheel disc. After the joining of the connecting element in the wheel disc a portion of the head of the connecting element projects beyond the rim base on the outer side of the rim. Subsequently the head of the connecting element is at least partially removed.
