Definitions

  • This invention relates to disc brake assemblies for road vehicles. More particularly the invention relates to a brake and suspension assembly for a road vehicle.
  • One conventional construction of disc brake for the front wheels of motor vehicles includes a bracket which is secured to the steering knuckle of the vehicle, the bracket carrying pins on which is mounted a caliper which straddles the brake disc and which contains one or more piston and cylinder assemblies. As hydraulic fluid is supplied to the cylinders, the brake pads on either side of the brake disc are forced into engagement with the brake disc by the pistons and the caliper slides on the pins on the bracket.
  • GB-A-1 427 245 discloses a disc brake in which a double-acting piston and cylinder device is mounted in an aperture in a housing and arranged so that, upon actuation, the piston applies one pad directly to the disc and the other pad is applied by the cylinder acting through a yoke which straddles the brake disc.
  • this brake the rotational drag on the one pad is taken directly by the housing and the rotational drag on the other pad is transmitted to the housing through the cylinder.
  • the housing is connected to the suspension of the vehicle. The transmission of the rotational drag of one of the pads to the housing through the cylinder will tend, in practice, to jam the cylinder. Moreover the weight of the assembly will be considerable since the housing is separate from the vehicle suspension.
  • a brake assembly for a road vehicle comprising: a support structure, a first aperture in the support structure, a wheel bearing having relatively rotatable inner and outer parts with one of the parts secured to the support structure so that the other part passes through the first aperture, a brake disc mounted on said other part of the wheel bearing in an axially fixed position adjacent to and at one side of the support structure, a double-acting, hydraulic piston and cylinder device having its cylinder mounted for axial movement on the support structure, bridge means spanning the periphery of the brake disc and integral with or secured to said cylinder, two brake pads mounted on the support structure, one on each side of the brake disc, complementary abutments on one of the brake pads and on the support structure which engage to react the forces tending to rotate said brake pad during braking; the arrangement being such that the piston of the piston and cylinder device operates directly on one of the brake pads and the cylinder operates on the other brake pad via the bridge means and so that upon admission of hydraulic fluid to the piston and cylinder device to increase the effective length

  • the bearing 20 will preferably be a sealed- for-life bearing and may, for example, be made in two parts with a grease reservoir between the parts
  • Each brake pad consists of a friction lining and a backing plate shown at 28 and 29 respectively
  • Each backing plate is provided with ears, shown at 50 in Figure 4, which engage with tracks 30 on the knuckle to resist rotational forces when the brake is applied
  • a first yoke 31 Secured to the left hand of the cylinder 22 in Figures 1, 2 and 4 is a first yoke 31 which is connected by rods 33 to a second yoke 34 which engages the backing plate 29 of the brake disc 27 and is centred by a dowel 29a on the backing plate 29 in Figure 2 and on the yoke 34 in Figure

  • the cylinder 22 can slide in the bearing 20 which as mentioned above is preferably a sealed-for-life bearing and this arrangement ensures that there is no unwanted stress on the seal 25.

  • the means which provide the clamping forces on the pads are thus separate from the means which take the reaction of the rotational drag forces on the pads.
  • the invention has been described with reference to two yokes 31 and 34 which are connected by rods 33.
  • this assembly may be replaced by a flanged assembly made of sheet metal of appropriate thickness or the rods may be replaced with profiled elements if they have to take any substantial force on braking. The closer the rods are the less the force will be.
  • the abutment members could be connected together at their ends remote from the knuckle if desired.

Abstract

L'invention concerne un ensemble frein pour un véhicule à moteur. Cet ensemble comprend: un élément support (10) présentant deux ouvertures (11, 12); un disque de frein (17), monté de manière à pouvoir pivoter à proximité et sur l'un des cotés dudit élément support sur un roulement de roue (13), monté à l'intérieur de l'une desdites ouvertures; un piston hydraulique à double effet; un cylindre (23), conçu pour adopter un déplacement axial dans le roulement (20) de l'autre ouverture; et deux plaquettes de frein (26, 27), montées de chaque coté du disque de frein. Selon cet assemblage, le piston (24) sollicite directement l'une des deux plaquettes de frein, le cylindre étant pourvu d'éléments en pont (30, 36) recouvrant le contour du disque de frein. Le piston sollicite également l'autre disque de frein, les forces ainsi exercées tendant à faire pivoter lesdites plaquettes lorsque le frein est activé par l'intermédiaire de l'élément support. Cet élément support peut par ailleurs se présenter sous la forme d'un joint orientable, faisant partie de la suspension d'un véhicule à moteur.
