Abstract:
Method to manufacture a panel comprising a substrate with at least one surface of plastic material and further comprising at least one component adhered to the surface of plastic material of the substrate, whereby at least the plastic surface of the substrate to which such component is to be adhered, is manufactured by way of a primary forming process, whereas the at least one component (12, 12.1, 12.2) is adhered to the substrate using the bonding properties of the plastic compound effective during the primary forming process forming the plastic surface when manufacturing the substrate, which method is conducted using the following steps: - providing a mould (3) having a mould surface with at least one holding fixture (6, 6.1) being a recessed area with respect to the adjacent mould surface (5), - providing a pre-manufactured component (12, 12.1, 12.2) to be adhered to the plastic surface of the substrate, - providing a plurality of inserts (9, 9.1, 9.2, 9.3, 9.4,) wherein at least two different inserts (9, 9.2, 9.4) are adapted for being alternatively inserted into one and the same holding fixture (6, 6.1,) of which inserts at least one of which is a component support (9, 9.1, 9.2, 9.3,) and choosing one of said different inserts (9, 9.2, 9.4) for insertion into a holding fixture (6, 6.1,) - inserting into one or more of the holding fixtures (6, 6.1) a component support (9, 9.1, 9.2, 9.3) in a sealing arrangement with the inner surface of a holding fixture (6, 6.1, 6.2) and provided with at least one receptacle (11,11.1, 11.2) adapted to at least partially accommodate the pre-manufactured component (12, 12.1, 12.2) to be adhered, the receptacle (11, 11.1, 11.2) being designed so that the surface of the component (12, 12.1, 12.2) not being accommodated within the receptacle (11,11.1,11.2) and facing in the direction of the mould surface forms part of the effective mould surface, in which receptacle (11,11.1,11.2) a component (12,12.1,12.2) has been or is introduced prior to the following steps, - applying the substrate forming plastic compound C onto said mould surface, - allowing the plastic compound C to harden, and - demoulding the substrate with the at least one component (12,12.1,12.2) adhered to one of its surfaces from the mould 1 and thus having manufactured the panel. Further disclosed is a panel 17 for use as part of a trim panel and a mould system for manufacturing such a panel.
Abstract:
Ein elastischer Fahrzeugreifen (1) umfasst einen Reifenhohlraum. Dieser ist eingefasst durch einen die Lauffläche (3) tragenden Laufstreifen (2) und einer an jeder Seite des Laufstreifens (2) angeformten Seitenwand (4, 4.1). In dem Reifenhohlraum ist ein schalldämpfender Einsatz (9) oder eine darin angeordnete schalldämpfende Einsatzanordnung vorgesehen. Zwischen dem Schalldämpfungseinsatz (9) oder der Schalldämpfungseinsatzanordnung befindet sich, angeschlossen an die Innenseite (10) des die Lauffläche (3) tragenden Laufstreifens (2), eine sich in Umfangsrichtung des Laufstreifens (2) erstreckende Ventilationslage (13) mit einer zumindest in Quer- und oder Längsrichtung des Laufstreifens (3) luftdurchströmbaren Struktur. Diese ist geeignet zum Durchlassen eines zumindest teilweise in Kontakt mit der Innenwand (10) des Laufstreifens (2) stehenden Luftstroms.
Abstract:
A human powered land vehicle has two steered front wheels (3, 3.1) and at least one rear wheel (2) driven by a drive train. The drive train incorporates a human powered actuator (13) to be actuated for propulsion of the vehicle (1) by a person driving the vehicle (1). This actuator (13) is cinematically coupled to the rear wheel (2) for propulsing the vehicle in at least one driving direction. A first suggestion is defined - in that the axis A 3 of the human powered actuator (13) is arranged in the longitudinal extension of the vehicle (1) in front of the axis A 1, A 1.1 of rotation of the front wheels (3, 3.1), - in that three dimensions are defined in the x-y plane of the vehicle, which are (a) a distance d1 between the centre B of rotation of the axis A 2 of the rear wheel (2) and the centre D of rotation of the axis A3 of the human powered actuator (13), (b) a distance d2 between the centre A of rotation of the axis (A1, A 1.1 ) of the front wheel (3, 3.1) and the intersection point C of a line connecting the centre A with the x-axis of the vehicle (1) the connecting line being perpendicular to the x-axis of the vehicle (1), and - (c) a distance d 3 between the centre B and the intersection point C, whereas distance d1 has a value of 1235 mm ± 15 %, distance d2 has a value of 1 132 mm ± 15 %, and distance d3 has a value of 379 mm ± 15 % and - in that the ratio between the squared distance AB2 between the centre B and the centre A and the squared distance AD2 between the centre A and the centre D is within the range between 2.8 to 15.3. According to another suggestion the ratio of the distance of the front wheels (3, 3.1) from each other measured in the height of their axis A1, A1.1 of rotation and the diameter of the front wheels (3, 3.1) is in the range from about 1.3 to about 1.7. The axis A 3 of the human powered actuator (13) is arranged between the two front wheels (3, 3.1) within their projection to each other in the traverse direction of the vehicle (1) and in the vertical direction above the axis A1, A1.1 of rotation of the front wheels (3, 3.1) and in the longitudinal extension of the vehicle (1) in front of the axis of rotation of the front wheels (3, 3.1).
Abstract:
An elastic vehicle tyre with a cavity (11) enclosed by a tread strip (2) supporting the tread (3) and sidewalls (4, 4.1) adjacent to this on both sides shows a foam insert (9) connected to the inside (10) of the tread strip (2). The side walls each carry a bead (5, 5.1) disposed at the free end to fit around the flange (8, 8.1) of the rim (6) of wheel (7). The foam insert (9) partly fills the cavity (11) and serves a dampening function, in particular in a frequency range below 400 Hz.
