The technical FIELD

The present invention relates, generally, to blocks of brake pads used in brake systems of vehicles, including disc brake system and drum brake cars. These systems can be used in cars, trucks, buses, road equipment, aircraft, self-propelled machines etc. More precisely, the invention relates to an improved site, the friction brake lining, which design significantly reduces brake noise generated during operation of the brake system, and ways to create an improved unit of the friction brake lining.

The LEVEL of TECHNOLOGY

Fluctuations in the block of the friction brake lining, generated during the operation of the brake system, often end with a loud grating noise, which can be unpleasant for hearing and/or to seem an alarm to the driver, even if the noise does not occur because of any functional fault of the car. In some situations, fluctuations in the block of the friction brake lining can even contribute to premature or uneven wear of the abrasive surfaces of the brake system. In any case, excessive brake vibration and noise are undesirable, and it was suggested many different sposabella reduction or damping of mechanical vibrations in the block of the friction brake lining.

Well-known examples in this field of technology, aimed at reducing the noise of the brake system when it is working, include cutting sinusoidal grooves in the base plate, as described in U.S. patent 6,283,258 and milling of the friction lining, as described in U.S. patent 5,456,339. However, these known methods create unwanted side effects such as increasing the duration of manufacture and/or increase the value of the node of the brake disc or drum.

In particular, one effective way to reduce the noise of the brakes without these unwanted side effects consists of applying strips on the rear surface of the base plate. The strip may be extruded through the holes in the base plate, as described in U.S. patent 5,413,194. This pad can be introduced in the manufacturing process of the brake unit or fixed in subsequent operations.

In U.S. patent 5,413,194 friction material mixed or placed on the bottom layer in the extrusion process through the holes in the base plate, and flows of material in alternative embodiments of the invention have been introduced, the rear support plate to form a composite noise attenuation pad. Extrusion holes in the base plate, through which is fed a mixture of friction of the materials or the flow of the mixture of the lower layer were made round. Round holes IP is resultsa because of the simplicity of their manufacture, using the process of perforation, and low cost form of a round hole tools punch. In some cases, braking, fluctuations along the base plate, are a source of unwanted noise brakes, and the gasket on the rear surface of the base plate is insufficient for satisfactory reduction of unwanted vibrations.

Thus, when using a friction block brake lining having extrusion openings in the base plate, through which is injected under pressure a mixture of frictional materials or a mixture of lower layer formation process, as described in the mentioned patent, there is a need to provide additional sound absorption properties without increasing the cost base plate or increasing the duration of the manufacturing process of the brake Assembly.

BRIEF description of the INVENTION

The unit of the friction brake lining in accordance with the present invention comprises a solid support plate, the length and thickness corresponding to the distance between opposite first and second surfaces. The base plate can transmit vibrations along the entire length and width. The base plate includes a primary extrusion hole passing through the thickness between its opposite surfaces. Creating the friction pad from presova the second material is pressed against the first surface of the base plate so that that the molding material fills the primary extrusion opening. The primary extrusion opening is non-circular shape, so that the waves propagating along the length of the base plate, it was extinguished on the entry in the specified non-circular primary extrusion opening.

The invention also relates to a method for damping oscillations passing through the block of the friction brake lining systems for disk brakes tick type. This method includes the following stages: formation of a solid base plate with the primary extrusion opening, passing at least two separate Assembly units, which are located mainly on opposite sides of the primary extrusion opening; pressing the molding material on the first surface of the base plate to form a friction element pads with simultaneous filling of the primary extrusion holes of the molding material; creating vibrations in the support plate divided between the mounting device and the excitation of vibrations, which are distributed not on the arc, as they are on the periphery of the primary extrusion opening, to thereby suppress fluctuations in the block of the friction brake lining.

It was found that in the friction lining with the extrusion of the werste in the base plate, through which the forming process is fed under pressure a mixture of frictional materials or a mixture of lower layer, the waves propagating across the support plate, mostly extinguished in the primary extrusion opening round. It is likely that this beneficial effect is created due to the presence of reflective surfaces, created a non-circular peripheral edges of the primary extrusion opening. This present invention differs from the round holes of the known technology, which, as we assume, allow mechanical vibrations freely pass on their periphery, as they spread across the length and/or width of the base plate.

In alternative embodiments of the present invention, the number, configuration and placement of extrusion holes on the thickness of the base plate is changed to change the frequency of natural vibrations and reduce noise during operation of the friction lining of the brake system.

A DETAILED DESCRIPTION of the PREFERRED OPTION

In all figures the same digital positions denoted by similar or corresponding parts in the various views of the friction lining disk brake according to the present invention, generally indicated by the position 10 in the figure 1.

The unit 10 includes a rigid support plate 12, which in the preferred embodiment, is made of steel. Base plate 12 has a length and a thickness between the opposing first surface 14 and second surface 16. The first surface 14 is a surface of the base plate 12, which is directed toward the rotor when the base plate is installed in the automotive brake system tick type. The first surface 14, a generally flat and a second surface 16 is also generally flat and is parallel to first surface 14. The base plate 12 also includes a top edge 18 and bottom edge 20 that is separated from the top edge 18. The top edge 18 and bottom edge 20 along the support plate 12 and form the top and bottom is Yu peripheral border. These nodes are installed in a vehicle braking system tick type. On the base plate 12 is installed, at least two separate mounting device 22, which serve as a support node 10 in the disk brake system. Figure 1-mounting device is shown as a simple profile design of base plate 12, whereas in figures 4-8 mounting device 22 is shown as tides, protruding in opposite directions from the base plate 12. Other configurations are possible with these devices, which are determined by the design of the brake system.

The base plate 12 also includes a primary extrusion opening, generally indicated by the position 24 passing between its opposite first 14 and second 16 surfaces. The primary extrusion opening 24 has a non-circular shape and may be slanted relative to the top 18 and bottom 20 edges. The primary extrusion opening 24 is described in more detail below.

The molding material, generally indicated by the position 26, tightly pressed on the first surface 14 of base plate 12 and the material 26 forms a friction pad 28 on the first surface 14 while filling the primary extrusion holes 24. As shown in figures 1 and 4-8, the friction element pads 28 may consist of two or more segments on a support or the e 12 or may be in the form of one section, as shown in figures 2 and 3. In the case of two or more segments, depending on the requirements of the designed brake system noise at the work of each lining segment may have a different flat configuration, different surface area or different thickness. Thus, the friction element pads 28 may have a contour surface 30 of the clutch, which allows to further decrease the noise level of the node 10. Although this is not necessary, it is preferable that each segment 28 such friction linings would be associated with his hole 24 in the base plate 12.

Preferably, although not necessarily to the sound-absorbing element plates 32 would be in contact with the main part of the second surface 16 of the specified base plate, as shown in figure 1. Sound-absorbing element plates 32 connected to the noise of the friction element pads 28 of the molding material 26 contained in the primary molding hole 24.

As shown in figure 1, the friction element pads 28 may be formed from a first mixture of the molding material 34, while the molding material 26 contained in the primary molding hole 24 and the sound-absorbing element plates 32 are molded out of the ordinary, mostly homogeneous second mixture of materials 36, with higher ones is acestu when formed, than the first mixture of material 34. Examples of suitable first 34 and second 36 mixtures molding material 26 can be found in the aforementioned U.S. patent 5.413.194. Regardless of the material selected for the second molding a mixture of 36, he should have thermal insulation and noise absorbing properties to reduce vibration.

Although this is not shown in the accompanying drawings, you can apply one or more optional intermediate layers of molding material 26, each of which is connected to another layer and with base plate 12 when the molding material under pressure. The intermediate layer typically will have insulating properties and/or samopodavlyayuschie properties.

As shown in figure 2, the molding material 26 may consist of ordinary, mostly homogeneous sand used to create the friction lining plates 28, and a noise-absorbing element 32.

Figure 3 shows another variant of the invention, in which the sound-absorbing element pads are not formed at the same time with a friction element pads 28. In this case, the sound-absorbing element pads may be formed separately and attached a subsequent operation, or completely omitted depending on the application and circumstances. New advantages of the present invention, the real is in turn supported in the version of figure 3 with the primary extrusion holes 24 in the base plate 12, through which the waves propagating from one end of base plate 12 to another, mainly, will be significantly reduced in amplitude, as described in more detail below.

Referring now to figure 4, it can be seen that the base plate 12 has a secondary extrusion opening 38 near the primary extrusion opening 24. Secondary extrusion opening 38 is filled with the molding material 26 simultaneously with the filling of the primary extrusion holes 24. Preferably, the secondary extrusion opening 38 also has a non-circular shape in the case of figure 4 is formed in the form of an elongated slot having a mirrored orientation on the base plate 12, or in this case, basically, the perpendicular orientation of the primary extrusion holes 24. Although in this figure the friction element pads 28 are shown as segmented with the primary 24 and secondary 38 forming holes associated with the respective segments, it should be understood that this configuration of the extrusion orifice may be equally effective and not segmented friction element pads 28.

Figure 5 shows a slightly modified configuration of the extrusion holes, in which three secondary molding holes 38 are made in the base plate 12 together with the primary extrusion of the opening 24. In this example, one of the secondary extrusion openings 38 are made as two elements with the primary extrusion opening 24 which have the form of parallel elongated slots associated with the corresponding segment of the friction element pads 28. The other two secondary molding holes 38 is designed as a parallel pair and associated with another segment of the friction element pads 28.

In figures 7 and 8 shows an additional configuration of the shape and orientation of the primary 24 and secondary 38 of extrusion holes. For example, in figure 7 the primary extrusion opening 24 has a conventional T-shaped, and the secondary extrusion opening 38 has a similar form, but the mirror is oriented with respect to the primary extrusion opening 24. In figure 8 the primary extrusion opening 24 made in the form of letters "H"and the secondary extrusion hole 38 made in the form of the letter "H", but in mirror orientation with respect to the primary extrusion opening 24. These above examples simply offer different possible configurations of extrusion openings 24, 38. And, although in each example, the secondary extrusion opening 38 is shown in a mirrored orientation relative to the primary extrusion holes 24, it is not necessary for this design.

what, however, in all these examples, the extrusion openings 24, 38 include at least one linear edge 40, which is basically oriented at an angle to any of the top 18 and bottom 20 edges of base plate 12. It is assumed that this feature increases the efficiency of the noise absorption device according to the present invention. Specifically, the waves propagating along the length of the base plate, mostly extinguished when entering a non-circular extrusion hole 24, 38 and then further reduced by reflection from the linear edge 40.

Another advantageous characteristic, inherent in the above examples, is the preferred absence of any sharp corners, both concave and convex, in the molding holes 24, 38. Again referring to figures 4-8, we see that each shows them extrusion hole 24, 38 includes at least two concave angle 42. Concave corners 42 have a certain radius of curvature; in the preferred embodiment, the radius of curvature equal to at least the thickness of the base plate 12, however, can be used and smaller radii of curvature, providing the same advantageous effect. Similarly, in figures 7 and 8 show examples in which each extrusion orifice 24, 38 includes at least one convex corner 44. Convex angle 44 also has a certain radius of curvature. This radius of curvature for the corners 42, 44 in forming the openings 24, 38 serves to reduce the possible stress concentration in the base plate and the easy techniques of forming holes, using cheap punch instead of using electrical discharge machine (EDM) or laser cutting.

The brake block friction lining 10, having extrusion openings 24, 38 in the base plate 12, in which zapressovyvajutsja molding material 24 during the operation of forming effective and useful modifies the waves propagating from one end of base plate 12 to the other end. It is assumed that these beneficial effects are achieved by performing extrusion openings 24, 38 non-circular shape. A non-circular shape can be optimally configured to reduce the risk of blocking of the block brake lining 10 and disturbance of the structural integrity of the base plate 12 when the brake system. Different a number of different configurations and placements of extrusion openings 24, 38 in the base plate 12 have different noise-canceling effect when using the brakes. Preferably, the number, configuration and placement of extrusion openings 24, 38 are selected and adjusted in such a way as to change the natural frequency of oscillation of the support plate 12, in order to reduce the risk of blocking components of the brake, which is the likely source of noise brakes when using it in the vehicle. An additional benefit of a large surface area occupied by forming the holes is 24, 38 in the base plate 12 is in the presence of increased amount of sound-absorbing material 26 in the brake unit 10.

Professionals it is clear that there may be various modifications and changes of the present invention based on the above description. For example, new features of the invention can be implemented in combination with one or more round holes prior art in the support plate 12. For example, as shown in figure 4, a non-circular extrusion hole 24 can be used in tandem with a round hole 46 in order to achieve incremental benefits, and, thus, to create another form of the second extrusion holes. It, therefore, can be made without leaving the spirit and scope of the invention covered by the claims.

SUBSTANCE: one or more brake shoes of disk brake are arranged on fastening plates or on other supports for shoes and/or caliper or like device. Caliper or like device and support for shoes are made for taking up resultant counteracting forces at braking in plane perpendicular to surface of contact between caliper or like device and each support for shoes. Calculated point of action of resultant counteracting forces is within the limits of said surface of contact to provide balancing of brake shoes, thus excluding tendency of turning of shoe supports from caliper or to center of brake. Said calculated point of action of counter acting forces is found from following equation where Heq is perpendicular distance from plane through center of brake disk in which point of action of counteracting forces is found; Ry and Ri are radii from center of brake disk to outer and inner sides of brake shoe; α is angle between line passing through center of brake shoe and center of brake disk and corresponding end of brake shoe.

EFFECT: optimization of position of point of action of counteracting force and taking up of counteracting force in one plane.
