Conventional brake discs of bicycle disc brakes have in the middle a ring in which six attachment holes are arranged. Furthermore, it is known to attach brake discs of bicycle disc brakes by means of an adapter (a centerlock adapter or central adapter) to the wheel hub of the bicycle. The known adapter has an internal toothing, which cooperates with an external toothing of a wheel hub. The adapter also has on its outer side projections which engage in recesses of a specially adapted brake disc. To mount the brake disc with a Centerlockadapter the adapter and the loosely connected brake disc are arranged on the wheel hub and fastened by means of a central screw to the wheel hub, so that a firm connection between the wheel hub and brake disc is formed. The central screw has an external thread, which engages in a corresponding internal thread of the wheel hub.

This known mounting of brake discs with a centerlock adapter has the disadvantage that both the centerlock adapter and the brake disc must be kept in the correct position when the central screw is fastened to the wheel hub. There is also the disadvantage that specially adapted to the centerlock adapter discs are used, which are not suitable for attachment to a conventional hub, which is not designed for the use of a Centerlock adapter.

The invention is therefore also an object of the invention to provide a brake disc assembly which is easily mounted on a hub with a central screw and / or in which a brake disc can be used, which is also reversible on a hub without Centerlockadapter.

This object of the invention is achieved with a brake disk assembly according to claim 1. Advantageous embodiments of the invention are specified in the dependent of claim 1 claims.

According to one embodiment of the invention, a brake disc assembly for a hydraulic disc brake of a handlebar-guided vehicle, in particular a bicycle and / or motorcycle, with an adapter (or centerlock adapter or central adapter) and a brake disc is specified, wherein the adapter has an internal toothing for twist-proof connection with a Wheel hub of the handlebar-guided vehicle and driver for rotationally secure connection with the brake disc, wherein the brake disc assembly comprises a connecting member for captive connection of the brake disc with the adapter.

This design of the brake disc assembly has the advantage that the brake disc with the adapter forms a unit in which the brake disc is captive connected to the adapter. In other words, the brake disk can be connected to the adapter by the connecting member in an axial direction, at least substantially relative to the wheel hub. Preferably, the adapter is thereby only loosely connected to the brake disc, d. H. the connection should be sufficient to ensure that the drivers of the adapter engage in the brake disc. A firm connection, i. H. a compound that allows no axial clearance between the adapter and brake disc is not necessary, because this is usually achieved in the assembly of the brake disc assembly on the hub, which can be done for example with a central screw having an external thread, which in a corresponding Internal thread of the wheel engages. By tightening the central screw, the brake disc assembly is firmly connected to the wheel hub. In this case, there is also a fixed axial connection between the adapter and the brake disc.

According to the invention, the brake disk can be arranged between the adapter and the connecting member and / or the connecting member can have at least one connecting element which can be arranged extending through an opening of the brake disk and with the adapter.

The at least one connecting element may preferably be a hook or a projection or arm provided with a hook and / or an undercut, which extends in the axial direction in particular with respect to the wheel hub. Preferably, the connecting element has such a dimension that it is characterized by the Mounting holes of a conventional brake disc can be inserted.

According to the invention, the connecting member may comprise at least one securing element for preventing rotation of a central screw, with which the brake disk assembly can be fastened to a wheel hub.

The connecting member may comprise a ring which is arranged parallel to the brake disc. Advantageously, the at least one securing element is arranged on the outside of the ring, d. H. that side of the ring which is adjacent to the central screw when the brake disc assembly is mounted. Preferably, the connecting member has a plurality of securing elements, which are advantageously distributed substantially uniformly on the ring. According to the invention, the ring may have areas in which the securing elements are arranged. In this case, the ring may be wider in these areas or have extensions. Between these areas, the connecting elements can be arranged. In one embodiment of the invention, six connecting elements are provided which each engage in an opening of a brake disc, which can be used for conventional attachment of the brake disc without central adapter. It is clear that fewer or more fasteners can be provided. For example, only one connecting element could be provided, with which the brake disc can be secured captively to the adapter. More preferred are embodiments with at least two connecting elements, which are preferably arranged opposite, d. H. in the circumferential direction by 180 degrees. Conceivable are also embodiments with, for example, three connecting elements, which are preferably arranged uniformly distributed over the circumference, d. H. offset by 120 degrees in the circumferential direction.

Hydraulic bicycle disc brakes with a brake caliper, a brake line, a connected to the brake line connecting member having an annular head, and a connecting member for connecting the connecting member to the brake caliper are known. The connecting member for connecting the connecting member to the brake caliper is in the known bicycle hydraulic disc brakes a hollow screw which projects through the annular head of the connecting member and connects the brake line via the hollow interior of the hollow screw with hydraulic channels leading to the pressure chambers of the brake caliper. The banjo bolts have the dual function of attaching the connecting link laterally to the brake calliper and establishing a hydraulic connection.

These known hydraulic disc brakes have the disadvantage that the hollow bolt must be sized relatively large in order to ensure a secure and sufficiently stable connection between the connecting member and the brake caliper. This results in a relatively large weight.

The invention is therefore also an object of the invention to provide a hydraulic disc brake, which ensures a safe and reliable function with a low weight.

This object of the invention is achieved with a hydraulic disc brake according to the feature of claim 4. Advantageous embodiments of the invention are specified in the dependent claims.

According to one embodiment of the invention, a hydraulic disc brake for a handlebar-guided vehicle is specified, in particular for a bicycle and / or a motorcycle, a brake caliper with a pressure chamber, a hydraulic connection bore and at least one hydraulic channel, from a connecting portion of the hydraulic connection bore to the at least one pressure chamber a brake pipe, a brake pipe connected to the connecting member having an annular head, and having a arranged in the hydraulic connection bore connecting member, wherein the connecting member has a connecting portion which is arranged in the head for hydraulic connection of the brake pipe to the connecting member, wherein the connecting member has an outer toothing and / or at its outer region at least one groove and / or flattening, which connects the connecting portion with the connecting portion hydraulically.

This embodiment of the invention has the advantage that the connection between the connecting member and brake caliper with the same dimensions of the connecting member is more stable or a link can be used with smaller dimensions, resulting in the same stability, a lower weight of the hydraulic disc brake.

According to the invention sealing elements may be provided between the annular head of the connecting member and the connecting portion of the connecting member, which seal in the axial direction of the connecting member and optionally in the radial direction of the connecting member.

In known brake calipers of brake discs for bicycles, the hydraulic connection bore is formed in a direction parallel to the axis of the brake caliper cylinders, in which the brake pistons are arranged and on Brake pads act to bring them with a brake band of a brake disc into engagement. The brake line is in the known hydraulic disc brakes for protection against damage in falls on the inside of the fixed frame part to which the brake caliper is attached, arranged. There is a risk that the brake pipe will engage the spokes of the impeller. To avoid this, in the known hydraulic disk brakes, the brake pipe is secured to the brake caliper with an angled connecting member to guide the brake pipe laterally outwardly away from the rotor. This results in the disadvantage that the brake pipe can only be led away from the brake caliper at a certain angle, which is defined by the angle in the connecting member.

The invention is therefore based on the object to provide a hydraulic bicycle disc brake, wherein the angle at which the brake line is led away from the brake caliper, within a certain range is easily adjustable. Furthermore, the invention is also based on the object of specifying a hydraulic bicycle disc brake in which the connection of the brake line to the brake caliper has a light and safe construction. The first and / or second object of the present invention is achieved with a hydraulic disc brake according to the features of claim 6. Advantageous embodiments are specified in the dependent claims.

This embodiment of the invention has the advantage that a change in the angle can be made by rotating the connecting member about the axis of the hydraulic connection bore, so that the brake pipe can be guided away from the brake caliper at a desired angle.

According to the invention, the angle between the direction of the hydraulic connection bore and the direction of the at least one brake caliper cylinder may be approximately 5 to 20 degrees, and preferably approximately 10 degrees, and / or the angle between the direction in which the connecting member extends and the direction perpendicular to the direction of the axis of the at least one brake caliper cylinder is about 5 to 20 degrees and preferably about 10 degrees.

According to the invention, the hydraulic brake may comprise a connecting member, which is preferably formed according to the above-mentioned features. According to the invention, the connecting member may be received in the hydraulic connection bore. According to the invention, the annular head of the connecting member may enclose the connecting member such that the connecting member is rotatably mounted about the axis of the connecting member or the hydraulic connection bore.

According to the invention, the connection member may be straight. Due to the angular arrangement of the hydraulic connection bore there is the advantage that the angle at which the hydraulic line extends away from the brake caliper can be changed by turning the hydraulic line around the connecting member.

In disc brakes, it is known to use open brake systems, that is, a compensation space is provided. Usually, therefore, an external surge tank is provided in the encoder fitting for a hydraulic brake system for a two-wheel, which is connected to the cylinder chamber of the encoder fitting for compensation holes. This has the disadvantage that the hydraulic brake system has a relatively large weight and a large space requirement. In addition, there are parts protruding from the sender armature. However, especially in the mountain bike area and in motorcycling, it is desirable to use systems that are as lightweight as possible and that have as few protruding parts as possible.

The invention is therefore an object of the invention to provide a sensor faucet, which is lightweight and has as few protruding parts.

wherein the compensation space at least partially surrounds the cylindrical wall of the cylinder space, and / or
wherein the compensation space is divided into at least two sectors, which are arranged laterally of the cylindrical cylinder space defining wall.

These embodiments of the invention have the advantage that the transmitter fitting with the compensation chamber can be made extremely compact, while at the same time a sufficient volume for the compensation chamber is provided. In addition, a sufficient stability is given.

For example, the compensation chamber can enclose at least 90 ° of the cylinder space, more preferably at least 120 °, more preferably at least 150 °, more preferably at least 180 °, more preferably at least 210 °, more preferably at least 240 °, even more preferably at least 270 °, more preferably at least 300 °, more preferably at least 330 ° and preferably enclose the entire circumference of the cylinder space.

The outside of the cylindrical wall bounding the cylinder space can of course also have an uneven shape. Advantageously, the outer wall is also substantially cylindrical, so that the largest possible volume for the compensation chamber is available.

A connection between the expansion chamber and the pressure chamber via the compensation holes takes place as long as the seal of the piston has not run over the compensation holes. Advantageously, in the piston receiving cylinder chamber opening openings of the compensation holes are arranged at least approximately the same with respect to the direction of movement of the piston, so that the openings of the compensation holes are run over simultaneously.

According to the invention, the compensation space can be divided over at least two webs into three sectors. For example, the sectors may be evenly distributed around the cylindrical wall of the cylinder space so that they each have, for example, a sector of 120 °. It is clear that a few degrees are to be deducted from the 120 °, which are determined by the strength of the sector bounding web.

According to a preferred embodiment of the invention, the compensation chamber can be divided into four sectors, each having approximately 90 ° and are divided by four evenly around the circumference of the cylinder space arranged webs at least in the lower region.

According to the invention, the individual sectors of the compensation space above the webs dividing the compensation space into sectors can be connected to one another. This has the advantage that the equalization chamber sectors can be sealed with a single bellows.

The seal is made via the seal 133 and 134 in both the radial and axial directions of the link 140 caulk.

10 shows an alternative embodiment of a disc brake according to the invention. The same components are denoted by the same reference numerals as in the 5 to 9 shown embodiment described. The following is based on the description of the embodiment according to the 5 to 9 and only the differences between the execution of 10 and the execution according to the 5 to 9 described.

The execution according to 10 differs from the remarks in the 5 to 9 in that in the annular head 131 of the connection member 130 Grooves are provided, in which the seals 134 respectively. 135 are arranged. Because of the arrangement of the seals 134 and 135 in each case a groove results in only a seal in the axial direction of the connecting member 140 ie that the seal 134 between the annular head 131 of the connection member 130 and the head of the link 140 seals, and that the seal 135 between the annular head 131 of the connection member 130 and the housing of the brake calliper 110 seals.

The hydraulic connection hole 111 runs in the brake caliper along one direction 152 facing the direction 151 the axis of the brake caliper cylinder 118 has an angle α. The connecting link 140 is in the hydraulic connection hole 111 arranged and also by the angle α with respect to the direction 151 the axis of the brake caliper cylinder 118 inclined. In the connection area 141 has the link 140 a preferably circumferential groove or depression, which communicates with the hydraulic channel 132 in the connection member 130 in hydraulic connection. In the illustrated embodiment of the invention, the connecting member 140 an external toothing 142 on that between the connection area 141 and the hydraulic transmission area 143 is arranged. Alternatively and / or additionally, the link 140 have a flattening, which is provided in the area in which in the in the 5 to 9 embodiment shown, the external toothing is provided.

The connecting link 130 is straight, that is, the annular head 131 passes without angle in the area where the line 120 with the sleeve 133 is attached. The connecting link 130 is with an annular head 131 at the connection area 141 of the connecting member, and about the axis of the connecting member 140 rotatable along the direction 152 runs. As a result of the oblique arrangement of the hydraulic connection bore 111 is the connecting link 130 also inclined by the angle α, in the 5 and 9 as an angle between the direction 154 in which is the firing link 130 extends, and the direction 153 that is perpendicular to the direction 151 the axis of the brake caliper cylinder 118 runs, is marked.

The angle α is approximately 10 ° in the embodiments shown in the figures. According to the invention, the angle α may also have a greater or lesser value, ie. H. for example, in a range of 5 to 20 ° and optionally also in a range of 5 to 30 °.

As a result of the oblique arrangement of the hydraulic connection bore 111 in the brake caliper can be the angle at which the brake line 120 is led away from the brake caliper, slightly by rotation of the connecting member 130 around the connecting link 140 be changed. The maximum angle at which the brake line is clearly led to the outside, results when the brake line is rotated exactly upwards. The further the brake pipe is turned horizontally, the lower the angle at which the brake pipe is led laterally outwards. If the brake pipe is led parallel to the ground, the brake pipe is not led outwards, but runs along the axis of the two-wheeler. Due to the oblique arrangement of the hydraulic connection bore also results in a simple and safe construction of the Anschussglieds, which can be formed straight because the angle to the routing of the brake pipe 120 created by the oblique arrangement of the hydraulic connection hole.

The brake calliper 110 comes with two flanges 117 attached to an unillustrated fixed frame part of a two-wheeled vehicle. The two side walls of the brake calliper are on hanger 181 and 182 connected with each other. Between the temples 181 and 182 a brake pad holder is provided. The stiffening areas or stirrups 181 and 182 are at an angle β to each other, which is approximately 60 ° in the illustrated embodiment. An angle in this range is preferred, but other angles are conceivable. The size of the angle also depends on the distance of the planes in which the stirrups 181 . 182 lie. The levels in which the brackets are located with the reference numeral 191 respectively. 192 designated. The smaller the distance between the levels 191 . 192 from the center line 193 is, the larger the angle β should be. According to the preferred embodiment of the invention, the spacing of the planes is 191 and 192 from the center line 193 approximately the radius of the cylinder bore.

In the temple 191 is also how in 38 to see the hydraulic connection hole 111 intended. If the hydraulic connection hole is not in the bracket 181 is provided, the bracket can 181 be carried out with a lower strength. For example, the bracket 181 then with the same strength as the hanger 182 be educated. In this embodiment, it is then preferred that the bracket 181 as well as the temple 182 a greater distance from the center line 193 in other words, that the material on the inner side of the bracket 181 is taken away.

According to the invention, the bracket 181 a greater height than its strength. In the illustrated embodiment, the height of the bracket is 181 about twice the strength of the strap 181 , This ratio is at the temple 182 even bigger.

Because of further details will be on the 35 to 38 as well as the comments on the embodiment according to the 5 to 9 respectively. 10 directed.
