The present invention relates to a disk brake self-propelled vehicles (cars). The present invention is to improve the braking performance disc brakes while reducing the cost of their production. The present invention is mainly intended for the automotive industry, but can also be used in other industry sectors.

Disk brake of a motor vehicle is usually located on the hub of at least one road wheel, which includes the axis of the wheel of a vehicle, and which serves as a support for the disc brakes. Disc brake associated with a wheel of the vehicle so that the wheel transmits rotational movement to the brake disk.

Disc brake includes a caliper, which form the first and second terminals, the first and second caliper clamps are placed against each other on both sides of the plane of the brake disc and are connected to each other outside. The first and second terminals of the support is supplied respectively to the first and second brake linings (pads). The brake pads are against each other on both sides of the brake disc so that their plane of symmetry is coplanar. This caliper is designed for compression of the first and second brake pads, through sootvetstvenno the first and second terminals, the first and second opposite surfaces of the brake disc. This disc brake also includes a holder (brake suspension)attached to the hub of the at least one wheel of a vehicle. The holder serves as a support for the caliper and at least partially adjacent to each brake pad side in the longitudinal direction relative to the direction of rotational movement of the brake disk.

During braking under the influence of the first and second terminals of the first and second brake pads are brought together in a perpendicular direction with respect to the plane of the brake disc. To ensure mixing of brake pads perpendicular to the plane of the brake disc, at least one of the brake pads being pushed to the brake disc by a piston placed in at least one of the terminals of the caliper. The piston has a pressure of, for example, on the first brake pad, trying to bring her to the brake disk perpendicular to its surface. This piston is moving under the influence of at least one brake circuit, which generates the hydraulic pressure exerted on the piston. Brake circuit, for example, may include brake master cylinder car. After that, the second brake lining pressed against the brake disk perpendicular is on its surface under the influence of the second clamp, moving in response towards the brake disk.

The holder allows the brake caliper to cover the brake disc on both sides. The term "cover" means that the caliper is placed on both sides of the surface of the brake disk, passing over it on top of its outer edge. The holder also allows you to set the direction of movement of the carriage during its forward return movement relative to the brake disk. Translational motion of the caliper occur during braking of the vehicle, causing the brake pads to snuggle up to each other through the brake disc. Return movement of the carriage arise upon termination of braking of the vehicle, causing the pads to spring up, moving away from the brake disk.

To maintain caliper covers brake disc position and to set the direction of its movement known application of the holes in the holder serving to house attached to the caliper guide pins, interacting with each other, the pins and holes allow for forward-backward movement of the caliper relative to the brake disk. These pins provide support for the caliper on the part of the holder, at the same time facilitating the direction of movement of the two pads to the brake disc. The holder with the holes is the top end of the stand is rnost brake disc, so going into these holes guide pins also pass over the top edge of the disk. The holder supports two brake pads in the desired position and disposes of a large part of the braking torque.

In the publication FR 2747751 describes the brake disc, have a bracket and caliper. This document describes that the two guide pins mounted on the carrier, and the holes made in the caliper. Each of these guide pins mounted so that its axis is parallel to the Central axis of the brake disc. More specifically, these guide pins are mounted so that the axis of one of them passes the outer edge of the circumference of the brake disc and extends on either side of him, and the axis of the other pin goes inside the same circle, and the second pin moves only from one side of the brake disc. This specific placing the axes of the pins allows to considerably reduce the distance between these two axes, resulting in minimizing the friction torque. As a result of this also minimizes the possibility of jamming of the pins and the slide can be carried out under optimum conditions.

However, this type of disk brake has the disadvantage of significant weight. The result also deteriorate the performance of its braking characteristic is cteristic.

To solve this problem, the present invention provides for reduction of the weight of the disk brake, while improving braking performance. In particular, the present invention provides that one of the brake linings is held rotatably by the holder, and the other brake pad is held rotatably by the caliper. Thus, it becomes possible to create a half bearing element extending from the plane of the brake disc only on one side. This form of holder brake pads makes it possible mainly to reduce the weight of the disk brake, and improve braking performance.

Thus, during braking of the vehicle the piston causes the first brake pad to move towards the brake disc, in this case, the first brake pad is held rotatably by the holder, while the second brake pad can stick to another surface of the brake disc under the influence of counter caliper, being held them with the possibility of rotation.

The movement of the caliper relative to the holder is caused by the interaction of the guide pins and corresponding holes. The present invention provides that the pins are mounted on the carrier, and from which Erste formed in the caliper.

The support plate may have at least one cut a hole improving, thus, the heat dissipation from the caliper. It also allows you to increase the width of the bending of the caliper, and also increase the stability of its design without changing the weight of caliper and even allowing it to reduce its weight.

Brake pads can be fastened to a support or holder by means of fasteners, including fasteners with screws, fastening at least one block or at least one spring.

The invention also allows to increase the diameter of the brake disk for the same wheel.

More specifically, an object of the invention is a disk brake for a self-propelled vehicle containing

caliper disc brakes, equipped with a hydraulic cylinder with a piston mounted slidable within the cylinder, and having a protruding portion and designed to cover the brake disc on both sides,

a holder attached to the vehicle, and the caliper is mounted for movement on the carrier, and a brake disc rotatably between the protruding part and the piston of the caliper,

two friction means mounted on both sides of the brake disc with the possibility of pressure to opposite sides of the piston and projecting part of the caliper, accordingly,

characterized in that the holder is made in the form of a half, passing only on one side of the plane of the brake disc, and guide pins pass over the brake disc perpendicular to its planes.

The present invention will be better understood from the following description and accompanying drawings, in which examples of the invention, the:

1 shows a disk brake 1 for a motor vehicle, is proposed in this invention. Disc brake 1 includes a support 2 and the holder 3. The caliper 2 is equipped with a hydraulic cylinder 4, a piston 5, which is fixed in the movable state in Utri that cylinder. The support 2 also has a front protruding portion 7. The holder 3 is fixed on the car and the caliper is mounted so that it can move on the holder 3. Between the projecting part 7 of the caliper 2 and the piston 5 of the same caliper 2 is mounted for rotation of the brake disc 6. The caliper is designed to cover the brake disk 6 from both sides. As noted above, the term "cover" refers to the fact that the support plate 2 is placed on both sides of the plane of the brake disc, connecting over him outside his circle. The brake disk 6 of its plane divides the caliper on the external (E) and internal (I) the side where the outer side is remote from the wheel hub (not shown) of the vehicle, and the inside is nearby in relation to this hub. Disc brake also includes two friction means 8 and 9 located on both sides of the plane of the brake disc 6. These friction means 8 and 9 can snuggle up to the opposite sides 10 and 11 of the brake disc under the relevant impact of the piston 5 and the protruding part 7 of the caliper 2.

According to the present invention, the first friction means 8 is held rotatably by the holder 3, and the second friction means 9 is held rotatably projecting part 7 of the support plate 2(figure 2 and 3). The holder 3 forms a plug containing intermediate part 12, the first shoulder 13 and the second arm 14, which are connected to the intermediate part 12 (figure 3). In a preferred example of the present invention (figure 2 and 3) the holder forms a half-bearing element. This bearing element is in a plane parallel to the plane formed by the brake disc. And he is not placed on both sides of the plane of the brake disk.

Two shoulder 14 and 13 and the intermediate part 12 of the holder 3 form a space

16, inside which is placed the first friction means 8 (Fig 3). Friction means 8, 9 consist of brake pads 8.1, 9.1 and supports 8.2, 9.2 brake pads (figure 3). Bearing brake pads connects the corresponding brake pad with a projecting part of the support or holder.

Each brake plate 8.1 and 9.1 has an inner side 21, 22, and accordingly the outer side 23 and 24, each of the outer sides facing away from the brake disk, and each of the inner sides located opposite the brake disk.

Caliper 2 covers the brake disk 6 with two sides having a generally U-shaped form (figure 2). The support plate forms a first branch 15 U-shaped and the second branch of the U-shaped, forming a protruding portion 7 of the caliper. Second friction means 9 OPI is moved in the protruding portion 7 of the caliper 2. The other branch contains 15 of the hydraulic cylinder 4, the piston 5 is fixed in the movable state inside the cylinder. The piston 5 can move the first friction means 8 in the direction of the brake disc 6.

In the first example embodiment of the invention, the caliper 2 is a one piece item. In another embodiment, the support may consist of two parts (not shown), the first part is a support for the piston, and the second part is a support for one of the friction means. The first part is connected with the second by means of fasteners, such as bolts.

The holder 3 includes two guide pins 17 and 18 which lie perpendicular to the plane of the brake disc 6 (figure 1). These pins 17 and 18 mounted respectively on the first 13 and second 14 the shoulders of the holder. The first and second guide pins can, at least partially, be tapped to enter the corresponding internal blind threaded hole, which is formed in the corresponding shoulder of the holder. Such pins can be manufactured by stamping or clotting in the roll of the source material.

Each guide pin 17, 18 is respectively along the axes 44 and 45, each of which is parallel to the axis 46 of rotation of the brake disc and perpendicular to the plane of the brake disc (1, 2). The units is eveda, the first and second pins should slide through corresponding holes 19 and 20. The first and second holes 19 and 20 formed in the support plate 2 and can take one pin each.

As shown by broken lines in figure 1, the holes are through-holes formed so that each of these two holes in its opposite edges goes to the internal (I) and external (E) sides of the caliper. The first hole 19 extends on the first edge 19.1 towards the inner side (I) of the caliper and on the second the first edge 19.2 towards the outer side (E) of the caliper. The second hole 20 extends on the first second edge 20.1 towards the inner side (I) of the caliper and on the second edge 20.2 towards the outer side (E) of the caliper.

Such through holes passing through the two edges, mainly facilitate machining of the caliper. In this case, more is not necessary to set the depth for holes. It is also assumed that the second edge 19.2, 20.2 holes are sealed by a plug (not shown), which is attached by screws inside the corresponding holes.

On the other hand, such through holes may allow the caliper to make the slide with accounting guide pins using one of the two edges of the hole, which is located near notransaction (I) caliper with one hand, and allow fixing screws second friction means 9 at the other edge of the hole remote from the inner side of the caliper (not shown). So one of the edges of the hole remote from the inner side (I) caliper, can be attached bearing 9.2 brake pads this second friction means 9. Securing this support 9.2 brake linings to this edge of the hole mostly avoids the need sealing plug holes.

In the end, these outlet openings can facilitate the notch of the disk brake on the outside of the car. In particular, at least one of the guide pins on one of its free end is equipped with a tool that allows you to use the device for unscrewing, such as the socket wrench.

The caliper has the possibility of sliding along the guide pins during braking and stopping braking on effective distance. The term "effective distance" means the distance of sliding of the carriage along the guide pins during braking of the vehicle. The magnitude of the effective distance can be measured along an axis parallel to the axis of the guide pin. The length of the holes in the caliper exceeds the effective distance slippage on the amount of allowable values of the wear of the brake loser is to and the brake disc. In one example, the thickness of the brake linings is 2 centimeters, allowing the guide pins into their respective holes in a length of from 3 to 5 centimeters. The permissible amount of wear thickness of brake pads and brake disc are measured along an axis parallel to the axis 46 of rotation of the brake disc or the axis of the guide pin 44.

Each brake pad can be connected with a suitable support with a small mounting tabs formed by each brake plate and intended to enter into the corresponding cavity formed in the support of the brake linings. In the example shown in figure 4, the second brake pad 9.1 can be connected with the second support 9.2 brake pads with the help of input projections, such as shown at number 28, which is formed by the second brake plate 9.1, corresponding cavity 29 formed in the second holder 9.2. The second brake pad 9.1 can be connected with the second support 9.2 using the premises of the projections 28 into the corresponding cavity 29. A protrusion and a cavity in figure 4 is shown in broken lines.

At least one friction means may be connected to a projecting part of the caliper and/or holder by means of projections and grooves, where the tabs 30, 31 are able to enter into the grooves 32, 33 formed in the hold who Le or in the protruding part of the caliper, such corresponding slots and tabs form elements for fastening the friction means to the holder or to the protruding part of the caliper. The grooves and projections are made in such a way that the corresponding brake pad almost cannot move relative to the caliper. The grooves and projections are also made in such a way that there is virtually no axial clearance between the prop brake pads, and a projecting part of the caliper.

The example shown in figure 4 schematically represents the second friction means 9 connected with a projecting part 7 of the caliper 2. This is the second friction means 9 includes brake pad 9.1 and support 9.2 brake pads. Second friction means is connected to a projecting part of the caliper through the support 9.2 brake pads. Bearing 9.2 brake pads has a first protrusion 30 and the second protrusion 31. Accordingly serving part 7 of the caliper has a first groove 32 and the second groove 33, which includes these tabs 31 and 30. The grooves and protrusions formed in such a way that bearing with the brake pad is connected with a projecting part of the caliper.

In the center of the protruding part 7 of the caliper, which serves as a carrier for the second friction means 9 may be cut hole 34, which will define the boundaries on both sides of this hole, the first wing 35 and the second is the snout 36 (Fig 3 and 4). This form of support can reduce the weight of the disk brake according to the present invention.

To keep the friction means on the protruding part or on the holder can be used spring, such as shown at number 41, attached to the corresponding support the brake pads and closely adjacent to the support or holder. In particular, in the example in figure 4, such a spring 41, which is intended to hold the second friction means on the protruding part 7 of the caliper, made of a metal strip 41, which may be placed between the first and second wings tightly to him and assigned support the brake pads. This spring 41 runs parallel to the plane of the brake disc and allows the second friction means to hold on to the protruding part of the support plate supporting the second friction means in a floating configuration with respect to the protruding part of the caliper.

The spring 41 connects the first and second wings, prisoedenysi second friction means with the help of fasteners. In particular, the spring 41 is made of a metal strip, which is locally deformed in the middle to create a receiving cavity 42 (figure 2). In this receiving cavity 42 is placed bulge 43, respectively, formed the backbone 9.2 brake nakedc is. Being on the convexity 43, the spring 41, on the one hand, firmly attached to the first wing 35, and on the other hand, the second wing 36. Metal plate formed by the spring 41 tends to rounding between the receiving portion 42 and each of the sections, where the spring 41 is pushed to the corresponding protruding wings.

In one embodiment, the at least one friction bearing means has at least first notch 38 and the protruding portion of the caliper and/or holder provided with a second notch 39. At least one removable block 37 is partially placed in the first and second recesses. Examples figa and 5b, the second friction means may be connected to a projecting part of the caliper with the help of block 37, partially placed in the first recess 38, formed the backbone 9.2 brake pads of the second friction means 9, and partially placed in the second recess 39 formed in the protruding part. The block 37 may be initially placed in one of the two grooves 38 or 39, and then either the second friction means or the caliper is applied to this block 37 to be installed to overlap the block 37 between the projecting part of the support plate and the second friction means. In the latter case, these notches 38 and 39 are predominantly not protrude outwards.

According to another variant of the invention the second Riccio is the main means may be connected to a projecting part of the caliper and/or holder by means of at least one of the bolt 47 and one nut 48 (6).

Each of the friction means has first and second protrusions 25 and 26 and the Central portion 27. In the example in figure 4 the second friction means 9 has first and second protrusions 25 and 26 and the Central portion 27. According to another variant of the invention, depicted in Fig.7, the tabs 25 and 26 of the respective friction means is increased in length and form a hook 50. The hook 50 figure 7 is represented by broken lines. This hook 50 together with the Central part 27 of the friction means restrict the installation cavity 51 within which a floating image is placed in the holder 3 or the protruding portion 7 of the caliper 2. With this purpose, the holder or the protruding part is formed thickening 52 complementary to the shape of the installation cavity. The installation cavity 51 and thickening 52 is performed so that the friction means floating image is placed in the holder or support."Floating friction means is "push-pull" manner and thus is absorbed by the portion of the braking torque, contributing to the stability of the holder. In the example depicted in Fig.7, the first friction means is placed in zone 16. In the intermediate part 12 is formed of at least one thickening 52, complementary in shape to the installation cavity.

To facilitate the dissipation of heat from the one suggested in the present invention the disk tor the oz caliper may have at least one hole, such as shown at number 49 (figure 1). This hole allows you to reduce the weight of such disc brakes and also allows you to accelerate the heat produced during braking of the vehicle by reason of the friction of the brake linings on the brake disk.

The brake disc has a center and an outer edge, the center is the seat of the brake disk, where it is perpendicular to the plane of the disk passes the axis of rotation 46. The edge of the brake disc sets its boundaries. Forming the support material can be distributed in larger quantities in the vicinity of the first location and the second location are located along the edge of the brake disc and are against each other, than near the centre. More specifically, the caliper may have a greater amount of material in the first place, where forming the first hole, and in the second place, where he formed the second hole, than in the place corresponding to the center of the caliper. This distribution forms the caliper of a material mainly augments up to 20% of the absorption capacity under braking.
