Abstract
A shim includes a shim pad 4 of heat resistant composite material and a metal clip 3 which overlies the shim pad, locates it in position, and clips into a brake piston 9 in a calliper. The metal clips 3 preferably protects the shim pad 4 from direct contact with the piston and the metal clip preferably does not bridge over the shim pad and all the pressure from the piston is transmitted through the shim pad. The heat-resistant composite material can be used as an insulating material to form a barrier to reduce conduction of heat from the brake pad into the piston in a disc brake assembly; the material may comprise glass fibres; mineral fibres; aromatic polyamide fibres; asbestos fibre material with binder etc. As shown, clip 3 has three clip members 6,7 (8) fitting inside piston 9, a retaining clip 5 around edge of clip 3 locating pad 4. In the embodiment of Figures 4-6, a recess (14) acts as locating means for shim pad and the metal clip is extended to the side edges of the brake pad back-plate. An annular shim pad to match the piston shape could be used. <IMAGE>
Description
SPECIFICATION
Improvements relating to disc brake pads
This invention relates to disc brake pads, and more particularly to disc brake pads using shims behind their back-plate.
In a disc brake for a vehicle such as a car braking effort is applied to the vehicle by forcing disc brake pads consisting of friction material attached to a steel backing plate, against a brake disc. The force is applied to the disc brake pads by means of a hydraulic piston in a brake caliper, and it is usual in a brake caliper for a piston to bear against the back-plate of at least one disc brake pad. In some cases a caliper contains more than one piston, in others the caliper uses only one piston and one pad is forced directly against the disc, an opposed pad being dragged onto the disc by reaction forces.
Shims of various kinds are in common use on the back of disc brake pads mainly to reduce noise by damping effects, or in some cases to vary the centre of pressure of the piston.
Several methods are in use for applying the shims to the pads. In the case of a metal shim this may be made to clip onto the back-plate of the pad, gripping the back-plate at its edges. Alternatively the shim may be adhered to the back-plate either by means of pressure-sensitive adhesive or by means of a heat curable adhesive. In a further alternative a form of shim may be moulded onto the back-plate by heat and pressure during moulding of the disc-brake pad.
Various disadvantages and problems have arisen in the use of shims mentioned above. For example, where the shim has been applied by means of pressure sensitive adhesive problems have been encountered with the shims moving out of position under the influence of radial forces on certain brake caliper designs.
The use of a heat-curable adhesive is expensive and inconvenient in disc brake pad production and it is difficult to achieve a bond which will withstand the cyclic high temperatures to which the bond is subject during service.
Metal shims have the disadvantage that in general, they are not as efficient in damping out noise as non-metallic or metal/rubber sandwich varieties.
We have now found a means of applying and using shims which obviates many of the above disadvantages.
The present invention provides a shim for a disc brake pad which comprises a shim pad of heat resistant composite material and, to locate said shim pad in postion on the back of said disc brake pad a metal clip which overlies the shim pad, locates it in position and when in use clips into the end of a brake piston in a disc brake caliper.
The metal clip is preferably so arranged that it prevents direct contact between the piston and the shim pad, thus preventing the piston which is annular, from cutting into the shim pad. Preferably also the metal clip does not bridge over the shim pad so that all the pressure from the piston is transmitted through the shim pad and the maximum damping effect is thus obtained.
The metal clip is preferably in the form of a plate which will overly the shim pad, and will bear some form of location means for the shim pad, e.g. a recessed area into which the shim pad fits, or a plurality of projections to locate the edge of the shim pad. If desired the shim pad can be adhered to the metal clip.
The piston in a disc brake pad caliper is usually annular where it bears onto the disc pad back-plate.
Thus in the present invention the metal clip can be provided with upstanding clip members, preferably three or more, which will engage the interior wall of the annular piston.
The shim pad is a composite material which, when protected by the metal clip, will stand up to the pressures applied by a brake piston over a wide range of temperatures ie from below 0 C to over 400 C.
Suitable composite materials are those which contain fibre reinforcements not melted or severely degraded under the conditions of use, bonded with polymers which are preferably thermosetting, such as rubber eg nitrile rubber or resin eg phenolic; mixtures of rubber and resin may be used.
The composite is preferably a material with a relatively low thermal conductivity which will act as a thermal barrier between the back plate of the brake pad and the brake piston. This is to reduce heat flow from the disc brake pad to the hydraulic piston and hence the brake fluid which can be a problem, particularly when using non-asbestos brake pads which often have a much higher thermal conductivitythan asbestos ones.
Composite materials which may be used include compressed asbestos fibre material, which can have a binder consisting of rubber and/or resin, resin bonded glass fibre reinforced material, and the non-asbestos equivalent of compressed asbestos fibre jointing materials, which may be for example, a sheet of rubber bonded heat resistant fibres, such as glass fibres, mineral fibres or aromatic polyamide fibres. One such material is described in published
European Patent Application No 82 301151.5 (Publication No 0060664).
It is preferred that the composite material is one in which the fibres are substantially orientated in the plane of the sheet, in order to obtain good resistance to the compressive fibres exerted by the brake piston in use of the shim pad.
If desired the shim pad may be confined to the area of the back-plate on which the piston bears, especially if it is thermally insulating. This is to minimise the effect on heat dissipation from the disc-brake pad through interior overheating. It will be appreciated that in use the face of a disc brake pad is being rapidly heated by friction against the brake disc. If the back suface of the pad were covered with thermally insulating material the only surfaces left for heat dissipation would be the edges of the pad, which may be inadequate.
Thus the invention also provides in another aspect a disc brake assembly which comprises a brake caliper including at least one brake piston, a pair of disc brake pads and, interposed between the brake piston and that disc brake pad on which it is to bear when in use, a thermal conduction barrier which comprises a shim pad of a composite material which has a relatively low thermal conductivity and means to retain said shim pad in position between the disc brake pad and the brake piston.
The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings in which
Figure 7 is a rear view of a disc brake pad with a shim in accordance with the invention,
Figure 2 is a side elevation of the assembly shown in Figure 1, in which the brake piston is shown in section,
Figure 3 is a detail cross-section on A-A of Figure 1 showing a portion of the shim in position,
Figure 4 is a rear view of a disc brake pad with a shim which is a further embodiment of the invention,
Figure 5 is a cross-sectional view of the assembly shown in Figure 4on line B-B,
Figure 6 is a detail cross-section on A-A showing a portion of the shim of Figure 4 in position.
As shown in Figures 1 and 2 a disc-brake pad consists of a back-plate 1 on which is moulded a pad of friction material 2. A shim on the back-plate 1 consists of a zinc-plated steel clip 3 overlying a shim pad 4 of compressed asbestos fibre composite material. As shown in Figure 3 the steel clip 3 overlies the shim pad 4, there being a retaining clip 5 around the edge of the clip 3 which acts as a locating means for the shim pad beneath it. The clip 3 includes three upstanding clip members 6,7 and 8 which fit inside an annular brake piston 9 and engage its interior wall to hold the metal clip on the end of the piston.
In the alternative embodiment shown in Figures 4 and 5 a disc brake pad having a back-plate 10 and a pad of friction material 11 is provided with a shim comprising a steel clip 12 and a shim pad 13. In this case the clip 12 again overlies the shim pad 13 there
being a recess 14 to act as a locating means for the shim pad. In this case three clip members 15, 16 and
17 serve to attach the clip 12 to a brake piston 18, and the metal clip is extended inside portions 19, 20 out
beyond the shim pad to the side edges of the disc
brake pad back-plate to provide location in the brake caliper assembly and prevent the possibility of
rotation of the metal clip and shim pad.
In both the embodiments illustrated it will be
noted that the steel clips 13 and 12 do not touch the
back-plates 1 and 10 but the steel clips each form
plates, overlying the shim pad, onto which the
hydraulic piston can bear.
In each case the provision of location means for the shim pad means that the shim pad and clip could
be reduced in size so that the shim pad was located
only in the contact area of the piston. Indeed, an
annular shim pad to match the shape of the piston
could be used if desired.
