Definitions

  • the invention relates to a brake disc for arrangement in a vehicle to allow reduction of a speed of the vehicle by pressing first and second brake pads against the brake disc resulting in frictional interaction between first and second brake pad surfaces and corresponding first and second annular braking surfaces.
  • the invention further relates to a brake pad for use with the brake disc according to the invention, a braking system and a vehicle.
  • the invention can be applied in heavy-duty vehicles, such as trucks, buses and construction equipment. Although the invention will be described with respect to a truck, the invention is not restricted to this particular vehicle, but may also be used in other vehicles such as buses and construction equipment.
  • the brake pad may comprise a friction member and a structured coating on the friction member.
  • the structured coating may be applied to the friction member to achieve a surface profile cross-section of the brake pad surface that may be a scaled inverse of the surface profile cross-section of the brake disc surface of the brake disc according to embodiments of the present invention.
  • the surface profile cross-section of the brake pad surface may be scaled to exhibit smaller amplitudes than the surface profile cross-section of the brake disc. After an initial wear-in period, the surface profile cross-sections of the brake pad and the brake disc may fit perfectly with each other.
  • Figs 1 a-b schematically illustrate an example temperature distribution during braking and a possible resulting failure mode for a conventional brake disc
  • Fig. 2a is a partly cut-out perspective view of a braking system according to a first embodiment of the present invention
  • Fig. 2d is a partly cut-out perspective view of the braking system according to a second embodiment of the present invention.
  • Fig 2a is a partly cut-out perspective view of a braking system 1 according to a first embodiment of the present invention, comprising a brake disc 10, first 20a and second 20b brake pads, and a braking actuator arrangement 21 .
  • the brake disc 10 is attachable to a rotatable member of a vehicle by means of mounting holes 12 (only one of the mounting holes is indicated by a reference numeral for ease of drawing) so that the brake disc 10 rotates around a rotational axis 1 1 of the brake disc 10 when the vehicle is moving.

Abstract

L'invention concerne un disque de frein (10) pour l'agencement dans un véhicule pour tourner autour d'un axe de rotation (11). Des première et seconde surfaces de freinage annulaires (15a-b) s'étendent radialement entre un rayon de surface de freinage interne (Ri) et un rayon de surface de freinage externe (Ro). Chacune des première et seconde surfaces de freinage comporte une partie proximale annulaire (17), une partie distale annulaire (18) et une partie centrale annulaire (19). Au moins l'une des première et seconde surfaces de freinage est structurée pour faire saillie à partir d'un plan de base (16a, 16b) perpendiculaire à l'axe de rotation (11) pour présenter une section transversale de profil de surface (14a, 14b) avec un plan (24) comprenant l'axe de rotation (11). Une distance de saillie (ha(r), hb(r)) à partir du plan de base (24) jusqu'à la section transversale de profil de surface (14a, 14b) varie avec la distance radiale (r) à partir de l'axe de rotation (11) de telle sorte qu'une distance de partie centrale (dcentrale) est plus longue que chacune d'une distance de partie proximale (dproximale) et d'une distance de partie distale (ddistale).
