Definitions

  • the present invention relates generally to dis brakes, and in particular to a pin supported calipe which displaces friction members supported by the torqu support member.
  • Numerous disc brakes have been provide previously. Certain disc brakes may suffer generall from one or more of the following problems. If th caliper is suspended on pins at one side of the rotor, braking forces can cause the caliper to twist and distort which effects uneven loading on the brake shoes. Shoe guided caliper designs are generally not well suited for heavy duty usage. The spring clips utilized to keep the caliper in position tend to be troublesome. Calipers which have large contact surfaces and/or close tolerance fits with the anchor or torque support member develop sliding problems as corrosion builds up on the surfaces. It is highly desirable to provide a disc brake which eliminates the above problems.
  • a disc brake comprising a torque support member having an opening receiving a caliper, the support member having at least one pin extending axially thereacross and received in complementary-shaped opening means of the caliper in order to support slideably the caliper upon the support member, at least one friction member disposed within said opening, the torque support member having at one side of said opening an axially extending member, the friction member including a backing plate having at one side a first opening and on the other side an oppositely disposed second opening, the axially extending member of the torque support member received within the first opening of the backing plate and the second opening receiving therein said pin in order to support the friction member relative to the torque support member and caliper.

  • the disc brake of the present invention is indicated generally by reference numeral 10 in Figure 1.
  • Disc brake 10 includes a torque support member 12 having therein a central opening 14.
  • the central opening 14 receives therein a caliper 16.
  • Caliper 16 includes circuraferentially extending extensions 18, 20, 22, and 24 (see Figures 3 and 4).
  • Each circumferentially extending extension includes a recess 26 for slideably supporting the caliper relative to the torque support member 12.
  • the torque support member 12 includes axially spaced apart portions 30 each of which includes an opening 32. Received fixedly within openings 32 are pins 40 and 50.
  • Torque support member 12 includes axial extensions 60 and 70 which extend axiall toward one another within central opening 14.
  • Disc brake 10 includes an inner friction membe 11 and an outer friction member 13.
  • Inner frictio member 11 includes a backing plate 15 and outer frictio member 13 includes a backing plate 17. Friction memb

  • pin 4 may include thereabout a plastic sleeve member 42.

  • the piston member extends axially t engage inner friction member 11 and cause friction membe 11 to engage the rotating rotor 46 (see Figure 2).
  • the caliper moves toward an inboard direction whic causes the outer arm 16a ( Figures 2 and 4) to engage th outer friction member 13 and displace it into engagemen with the other side of the spinning rotor 46.
  • the rotor is engaged on both sides by frictio members 11, 13 and braking of the associated vehicle i effected.
  • the disc brake of the present invention provide substantial advantages in that no twisting forces ar imposed on the caliper by the pins 40 and 50.
  • Caliper 1 is free to slide axially with the friction members 11 an 13. Braking forces imposed on the friction members 1 and 13 are imposed uniformly and these forces ar transmitted directly to support member 12 via the axial extensions 60 and 70.
  • Caliper 16 is restrained positively against displacement from torque support member 12 by means of pins 40 and 50, so that brake 10 can be utilized in heavy duty applications. Spring clips can keep the caliper from effecting klunking noises during braking.
  • the disc brake of the present inventio provides sufficient clearance between caliper 16 and pins 40, 50 so that corrosion does not inhibit calipe movement. Because the loads imposed upon the pins 40, 50 would be relatively low, plastic sleeves such as sleev 42 (see Figure 2) can be utilized about either one o both pins to further reduce the effects of corrosion. Trailing friction members or brake shoes are utilized, thus the brake may provide a quieter operating brake.
  • the friction members 11, 13 are mounted by means of th annular openings 21, 29 to the axial extension 60, 70 o torque support member 12. Deflections of the suppor member 12 would not cause any loading or twisting of th friction members.
  • the caliper and support membe configurations are symmetrical castings.
  • caliper with three point mounting can also be utilized.
  • the caliper an torque support member configurations lend themselves t easy redesigning so that on one side of central openin 14 a pin 40 or 50 could be eliminated and an interlockin feature between the support member and calipe implemented, all without affecting the function of th brake.

Abstract

Le frein à disque (10) comprend un étrier (16) soutenu par des goupilles (40, 50) sur un élément de support de couple (12). Cet élément de support de couple (12) comprend, sur un côté d'une ouverture centrale (14), une paire d'éléments en saillie (60, 70) qui étendent axialement l'un vers l'autre. Les éléments de friction (11, 13) comportent chacun un plateau de frein (15, 17) qui a d'un côté une ouverture en forme d'anneau (21, 29) et, du côté opposé, une ouverture à encoches (25, 33). L'ouverture en forme d'anneau (21, 29) de chaque plateau de frein (15, 17) reçoit l'un des éléments en saillie dans le sens de l'axe respectif (60, 70) alors que l'ouverture à encoches placée du côté opposé (25, 33) sur le plateau de frein (15, 17) reçoit l'une (40) des goupilles (40, 50). Les éléments de friction (11, 13) sont accrochés relativement à l'élément de support de couple (12) et peuvent glisser axialement pour le freinage et pour compenser l'usure de la garniture de frein.
