Definitions

  • the invention relates to a chassis component having a first section made of fiber-reinforced plastic and a second section, wherein the first section and the second section have a common contact area, in which the first section and the second section are materially connected.
  • suspension components modularly, that is to say that they consist of different materials. Different materials or different fibers in fiber-reinforced plastics are also considered as different materials. There is the problem of permanently connecting the elements made of different materials, that is, they maintain their connection even during prolonged use, especially in large temperature differences.
  • one of the sections has at least one pin element which extends into the other section and forms a further connection between the first section and the second section.
  • the contact region can be realized by two planar surfaces, but it can also be cylindrically shaped contact surfaces. Other contact areas forming the contact area are also conceivable. From one of these contact surfaces in the contact area now protrudes a pin element, penetrates the other contact surface and thus forms a further connection between the two sections.
  • the mutually facing surfaces of the first and second sections are the contact surfaces.
  • the first section and the second section may also have further surfaces that have no contact with the other section.
  • the pin element may be any pin-like element. This means first of all only that it has a basically elongated shape. None should be said about their exact arrangement or the aspect ratio of longitudinal axis to transverse axis or the like.
  • the pin member has a greater rigidity than the first portion, more specifically as the matrix material of the first portion.
  • the pin element is therefore preferably harder or stiffer than the plastic in the first section.
  • the at least one pin element can be arranged in the first section.
  • the at least one pin element is arranged in the first section before the connection with the second section.
  • the pin element is connected to the second section, it is of course also arranged in this. More precisely, the at least one pin element is thus arranged in front of the connection with the two sections in the first section.
  • the at least one pin element can connect the first section and the second section in a form-fitting manner.
  • a material connection can also be realized without any material connection. With a positive connection, the durability of the connection is ensured, in particular in the event of temperature fluctuations.
  • a plurality of pin elements may be provided which interconnect the first portion and the second portion. It is basically conceivable that a part of the pin elements is arranged in the first section and another part of the pin elements in the second section prior to assembly. Preferably, however, all pin elements are arranged in one of the two sections prior to assembly.
  • the plurality of pin elements is arranged on a carrier.
  • all pin elements can be arranged on a carrier.
  • the assembly is simplified in that the pin elements as a prefabricated pin structure can be inserted in a single assembly step with the section to which it is to be connected first. First, the pin structure is thus connected, for example, to the first section, and as soon as this section is prefabricated, the connection to the second section is established.
  • the second portion may be metal.
  • the second section may be made of fiber reinforced plastic.
  • either the matrix material of the first section and the second section may differ.
  • the matrix material of the first section and the second section are the same.
  • the difference of the material may consist in that short fibers and / or long fibers are contained in the second section, while the first section contains at least one continuous fiber unit.
  • the first section may additionally also contain short fibers and / or long fibers, but it is preferred that the first section contains as fiber material only continuous fibers or an endless fiber.
  • the continuous-fiber unit can be designed as a single continuous fiber or as a ringing.
  • the endless fiber unit may be formed as a winding structure. But it can also be a braided structure.
  • the at least one pin element can be cylindrical.
  • the at least one pin element may be wave-shaped. A waveform automatically results in a positive connection as soon as the second section encloses the pin element.
  • one part may be cylindrical and one part may be in the form of a wave.
  • all pin elements have the same shape.
  • the at least one pin element can be arranged obliquely on a support. This means that the pin element is inclined to the contact surface stands. In the case of several inclined pin elements, such positive locking can be achieved.
  • the pin element may consist of a section of an endless fiber.
  • the at least one pin element can be arranged on a carrier made of fiber-reinforced plastic.
  • the first section and / or the second section can store a force introduction element, in particular a joint.
  • a permanent connection of the sections is particularly advantageous since, in addition to temperature fluctuations, stress also occurs due to introduced forces.
