Definitions

  • the present invention relates to a wheel hub and brake disc arrangement for a vehicle wheel, comprising a hub rotatably carried on a shaft portion and presenting an outwardly facing region of non-circular cross-section, and a brake disc which is carried by said region of the hub, said brake disc having a central hole, the shape of which is adapted to the shape of said non-circular cross-section to thereby provide a mutually non-rotatable attachment of the brake disc to the hub.
  • Brake discs for disc brakes have previously predominantly been attached to their hubs in either of two ways, namely either by being manufactured as an integral part of the hub or by being securely screwed to a circular flange on the hub.
  • the former method is essentially restricted to brakes for lighter vehicles, whilst the latter is also suitable for medium-sized trucks, for example trucks up to 16 tonnes in weight.
  • drum brakes have until now been almost exclusively used due i.a. to the extremely high braking torgue (around 2000 kpm) in combination with the brake shoes which apply the braking effect creating problems.
  • these problems are due to, on the one hand, the intense heating up of the brake disc as a result of the high braking force causing the disc to warp or upset ecause of its rigid attachment to the hub to thereby affec its alignment with the brake caliper and, on the other hand, the unavoidable heating of the braking surfaces of the disc * co a temperature higher than that of its hub region inflicting thermal stresses on the hub which may cause the hub to fracture.
  • An arrangement of this type is shown and described in DE-OS 1800 161 in which a three or four cornered transmission ring is attached to the hub, with the corners engaging in corresponding recesses in the central hole of the brake disc.
  • the arrangement also allows the disc to heat up more uniformally.
  • the object of the present invention can generally be said to develop a hub and brake disc arrangement which can replace previously employed drum brakes for the heaviest class of vehicles.
  • the object is to provide an interlocking connection between a hub and brake disc with which the risk of fracture of the hub of the disc due to thermal stresses is eliminated.
  • a wheel hub and brake disc arrangement of the earlier mentioned type which is characterized in that said non-circular region of the hub comprises a seguence of crests and hollows, and in that the central hole of the brake disc is provided with crests and hollows adapted to the shape of those of the hub, and in that between said hollows there are arranged hollows having a different shape to that of the crests on the hub.
  • the present invention ensures that the radial inner hub region of the disc can expand without the risk of fracture formation when the braking surface of the disc is subjected to an extreme temperature increase during braking and thus reaches a temperature which initially is substantially higher than the temperature of the hub region.
  • Fig. 1 shows a partial sectional elevational view of a wheel axle with a hub and brake disc arrangement according to the invention
  • Fig. 2 is an end view of the brake disc of Fig. 1;
  • Fig. 3 is a schematic end view of a section of the inner region of the hub and the disc
  • Fig. 4 is an end view corresponding to Fig. 2 of a second embodiment.
  • reference numeral 1 denotes an outer end of a rigid front axle of a truck.
  • the end of the axle presents a conical recess 2 in which a king pin 3 is affixed.
  • a stub axle assembly 4 is pivotally carried on the king pin 3.
  • the stub axle assembly 4 comprises a stub axle 5 on which a wheel hub 6 is carried by means of a bearing assembly 7.
  • the hub 6 carries a brake disc 8 and the stub axle assembly 4 a not-shown brake caliper or actuation mechanism.
  • the disc is affixed to the hub by means of an interlocking connection.
  • the hub 6 is provided with a central region which has a cross section which deviates from a true circle. More exactly, the region is provided with closely spaced V-shaped ridges 10 and troughs 11.
  • the radial inner hub region 12 of the brake disc 8 is provided with corresponding troughs 13 and ridges 14 which are adapted to cooperate with the ridges 10 and troughs 11 of the hub.
  • the depth of the troughs 11, 13 is somewhat greater than the height of the ridges 10, 14.
  • the troughs have a rounded base 15 whilst the ridges have a flat upper face 16 merging with flat flanks 17.
  • Such a construction ensures surface contact over the entire • flank surface of the ridges.
  • the disc 8 and the hub 6 are so dimensioned that, in an unloaded condition, a gap of 0.2 - 0.3 mm is present between cooperating flanks 17 on the disc and hub.
  • the hub and disc both have eighteen troughs and ridges.
  • the depth of the troughs corresponds to approximately 15% of the radius of the hole 16 in the disc. With a large number of troughs and ridges, for example thirty, the depth of the troughs can be around 5% of the radius.
  • the brake disc 8 is provided with slots 19 which extend radially inwards from alternate troughs 13 and merge into bores 18.
  • the shown disc is a so-called ventilated disc and the bores 18 with the slots 19 communicate with adjacent ventilation passages 20 in the disc.
  • Axial bores 21 are located between the bores 18, though these bores 21 lack the corresponding slots 19. Naturally, the bores
  • the bores 18 and the slots 19 can have a different shape.
  • the bores 18 may be more pronouncedly circular.
  • the slots can be narrower or wider with parallel opposed sides so that, in the latter case, the bores 18 are in the form of a semi-circle at the base of the slots.
  • the described arrangement with bores and slots allows the hub region of the disc to expand without the risk of it fracturing during heating of the disc friction surface 22 to a temperature higher than its radially inner hub region during braking.
  • a circular channel 23, open on one side of the hub is provided in the hub 6 radially inside of the ridges 10. In this manner, the heat transfer path through the hub material from the disc 8 to the hub region 24 which is pressed onto the bearing 7 is extended.
  • hollows 30 which are arranged between pairs of crests 14.
  • the depth of the hollows 30 corresponds to the height of the crests 14, and their width and slope of opposing side faces 31 are so adapted to a pair of crests that the pair fit in the hollow.
  • the disc 8 is totally symmetric. It is affixed to the hub 6 by means of a lock ring 25 located in a groove 24 in the ridges 10, a spring-washer 26 and a lock ring 28 located in a groove 27 formed towards the inner end of the hub.
  • the symmetric shape and the symmetric attachment, together with the axial movement on the hub which the spring-washer permits, results in symmetric thermal deformation, even wear of the disc's friction surfaces, minimal risk of brake torque variations, and simple assembly.

Abstract

Moyeu de roue et dispositif de disque de frein pour une roue de véhicule. Le moyeu de roue (6) comporte une partie avec des crêtes et des creux alternés en forme de V. Le disque de frein (8) comporte un trou central avec des creux (13) et des crêtes (14) correspondants de manière à bloquer de manière non rotative le disque sur le moyeu. Une rainure (19) s'étend depuis les creux alternés dans le disque de frein de manière à améliorer la dissipation thermique pour la partie moyeu du disque de frein.
