Definitions
- Motor vehicle brake comprising an interface configuration for an attached additional component
- Common motor vehicle brakes often include fixed caliper brake housings or floating caliper brake housings as actuators for generating the application force. While the fixed caliper brake housings also receive the friction linings in a rotationally fixed and axially longitudinally displaceable way, and the brake housing is allocated directly to the vehicle and non-rotatably, a floating caliper brake housing is non-rotatably and axially (in relation to a brake rotor axis of rotation relatively displaceable in parallel and relatively displaceable in relation to a brake holder allocated to the vehicle, which is also mounted to the The connection of any additional components is challenging not only because of the peculiarities of this relative displaceability of a floating caliper brake housing (displacement parallel to the wheel rotation axis in relation to the floating caliper holder).
- a cartridge is designed as a replacement filter insert for a housing, and this filter insert can be replaced when it is closed, ie when it is exhausted, as part of a maintenance operation.
- DE 102009021 203 A1 accordingly defines a so-called passive brake dust collection device for motor vehicles containing said filter medium.
- a filter housing is designed as a wire mesh, which surrounds the actual filter element.
- a strap-shaped fastening part is attached to the outside of the wire mesh, via which the folding and connection of the brake dust collecting device with a component that is fixed to the vehicle or the body can take place.
- a filter element on the housing of a To fasten brake caliper of an unknown type without this prior art containing any details about a specific interface agreement for the wheel brake-side housing cooperation partners.
- many approaches of the friction product collection that are logically variable in an installation space and reflect in an uncoordinated manner lack a basic guideline or coordination.
- the object of the invention is to present a new type of assistance to the professional world, so that an unrestricted and safety-relevant braking function in cooperation with any additional components such as in particular in connection with abrasion collecting devices regardless of the type of brake (fixed or floating caliper brake possible) is maintained unhindered, and in addition, the function or serviceability of the attached additional component is supported in a reliable, comfortable and particularly maintenance-friendly manner.
- FIG. 1a, b, c a rough sketch in three views for the purpose of illustrating a first problem solution according to the invention in connection with a bearing body in the form of a brake holder of a floating caliper disc brake, and
- FIG. 2 shows a perspective view of a second solution to the problem according to the invention, the bearing body property being integrated into a fixed caliper brake housing, and FIG
- the drawing according to Fig. 1a, b, c and Fig. 2 documents a regulated mutual interface configuration (mechanical and / or electrical) for a motor vehicle brake, which is both a practical, stable - mechanical mounting / fixing solution as well as an elastically tensioned or electrical interface configuration for electrical networking / electrification of an additional component, such as in particular for an abrasion collector, enables.
- the present invention is not limited in principle, but equally to the application for motor vehicle drum brakes, for
- Floating caliper lined disc brakes (containing a separate brake holder according to Fig. 1a, b, c for holding friction linings including brake housing support function, as well as for application for the bracketless fixed caliper lined disc brakes (Fig. 2) suitable and intended. All solutions are therefore expressly suitable for defining an interface agreement / interface standardization, because according to the present design in the cooperation of the respective bearing body with the assigned additional component (for example a
- Abrasion collecting devices or the like more a proper motor vehicle disc brake operation is still possible, taking into account all conditions as well as regularities and relevant rules of vehicle braking technology, safely, reliably and with maximum safety and a low number of components / weight.
- the invention includes an interface arrangement for motor vehicle brakes that is both efficient and maintenance-friendly and safe.
- the primarily mechanically defined interface according to the invention is primarily defined as a mutual mechanical attachment and installation interface. However, it is just as conceivable to either separate a bearing body and an attached additional component independently (in relation to the described mechanical
- Interface assembly or in addition, as in particular integrated into the mechanical interface assembly, so additionally to provide an electrical or electronic interface, which in particular, for example, is an electrical line connection between a vehicle electrical system or an electronic unit, on the one hand, and an electrical consumer, or sensor or the like, to or in the additional component on the other hand.
- This electrical equipment can include, for example, a sensor-based level monitoring with regard to the collected abrasion products and / or electrical consumption such as, for example, electrical suction, suction or processing means.
- an electrical interface assembly between a bearing body and an electrified additional component can be provided in addition to or separately from the mechanically mounted interface agreement, such as in particular independently, without departing from the core idea of a mutual interface agreement.
- a mechanical interface between the cooperation partners also includes the aforementioned electrical interface in the sense of multiple or double functions, that is to say integrated, whereby this integration is in principle just as conceivable in the opposite direction.
- a mechanical and / or electrical interface definition according to the invention between the bearing body and additional component which may alternately extend over all cooperating components in the sense of a plug-socket coding, consequently always ensures that only those that are mutually adapted and safety-approved for cooperation - i.e. suitable and certain cooperation partners - can be mutually paired without any incorrectly involved cooperation partners triggering and / or receiving mutual functional disadvantages, and in addition, the safety-related vehicle braking function is always possible regardless of a desirable abrasion collection function.
- the invention recommends that the mutual interface convention is primarily based on the vehicle brake's defined bearing body, which is fixed to the vehicle, and the additional component is fixed indirectly via the bearing body, whereas the vehicle brake is always independently designed to be self-sufficient from the bearing body.
- the present invention always enables a reliable vehicle brake function, even if the fixation in the interface between the bearing body and the additional component should be inadequate (for example as a result of improper maintenance, forgotten fixation or the like). Ergo, a defective additional component does not have any adverse effects / repercussions on the function or the fixing of the wheel brake system to be feared, as is, for example, the other way around.
- a preferred embodiment of the invention defines that the screw-on eyes for the screw-on fastening means are allocated in relation to a direction of rotation of the brake disk on the inlet side and / or on the outlet side.
- the axes of screw-on fastening means that are used to fix the additional component are not uniformly parallel but offset from one another - as in particular orthogonally offset from one another - are aligned.
- the three-dimensional offset may in principle include any spatial axis (tangential, radial, axial), as well as any intermediate values thereof.
- a mutual spatial offset which to a certain extent may include a kind of mutual interlocking component interlocking, also requires increased production costs, in connection with alternating alignment or coordination in the direction of spatial axes that are differently orthogonal to one another or otherwise arranged spatial axes, a significantly improved torsional strength, fixing function, rattle , Resonance frequency and noise resilience can be achieved.
- Such an improved assembled system network opens up a comfortable wheel brake solution for the first time, which allows all NVH criteria with the inclusion of all complex loads, because the appropriately specified inclusion of a chassis vibration excitation (that is, for example, preferably as a result of a vertically directed wheel foot point excitation at a wheel contact point as a result of a rough road stretch) is made possible when the vehicle braking operation is carried out at the same time (e.g. simultaneous service braking operation).
- a chassis vibration excitation that is, for example, preferably as a result of a vertically directed wheel foot point excitation at a wheel contact point as a result of a rough road stretch
- screw-on eyes are placed on the inlet and / or outlet side of the bearing body, i.e. directly on or in the fixed caliper brake housing, or the screw-on eyes are alternatively located on the inlet and / or outlet side on a holder arm of a floating caliper brake carrier.
- a cooperating coding or centering means of the interface agreement according to the invention can advantageously include a cavity (local female design of the bearing body made of cast material), for example a bore, groove, profile recess in the bearing body, and with only one additional component correctly positioned with it being appropriately coded trained, for example the male assigned designed engagement component / protuberance (s) (can also be designed as a pin, bolt, projection, shoulder, stamp, step, wedge) engages positively in the female cavity.
- the male assigned designed engagement component / protuberance can also be designed as a pin, bolt, projection, shoulder, stamp, step, wedge
- each bearing body and each additional component is alternately paired with both, i.e. with at least a cavity and are equipped with at least one protuberance next to each other.
- a preferred metal casting technology for representing the floating caliper brake carrier is associated with a fundamental preference for a female cavity design
- the male / female form-fit configuration described above in the assembly between the bearing body and additional component is basically just as reversed as, in particular, in connection with several coding areas a wheel brake can also be designed alternately mixed as desired, without leaving the core of a predetermined interface configuration that can be installed automatically and cannot be interchanged.
- the interface configuration and / or the electrical interface 4 may preferably be formed from an elastomeric material such as plastic material, rubber material or similar material.
- an elastomeric material such as plastic material, rubber material or similar material.
- the elasto element 11 seals an additional component configured as a memory or an electrical interface against moisture and moisture entering in an uncontrolled manner from the environment, so that stored substances cannot be flushed out in an uncontrolled manner.
- An elasto element 11 can also be inserted between the bearing body 2 and the additional component 3 as a vibration-related decoupling in order to avoid undesirable rattling noises.
- the quasi-hermetic seal is basically made possible by means of a closed ring shape.
- the elasto element 11 is to be arranged in an elastically clamped manner between the bearing body 2 and the additional component 3, protected as possible (dirt + stone chips).
- the preferred further developed variant therefore provides, for example, that the elasto element 11 is received largely optimally protected on or integrated in at least one contact contact surface in such a way that an air gap between the bearing body 2 and the additional component 3 is blocked. For example, this is done in an exemplary manner by the elasto element 11 in relation to a Contact system surface is at least partially lowered, as is received in particular offset in a groove depression of a flange.
- the elastomeric element 11 is in the form of an elastomeric, elastically compressible ring, which may be inserted separately and interchangeably as an additional elastomeric part, or, as an alternative, as a particularly easy-to-assemble non-detachable component component of an assembly (bearing body and / or additional component) is formed in one piece with it.
- the latter can be designed efficiently, for example, as a coating and / or application of a quasi-elastomeric plastic bead (application spraying).
- a quasi-elastomeric plastic bead application spraying
- At least one further elasto element 11 ' is also present separately or integrated (redundant elasto element 11, 11 1st redundancy variant).
- the sealing of the interface can also be combined with the above developments and designs, i.e. optionally additionally (2nd redundancy variant), possibly as a primary solution and / or as a rationalization of the 1st redundancy variant between bearing body 2 and additional component 3, defining a labyrinth seal.
- 2nd redundancy variant possibly as a primary solution and / or as a rationalization of the 1st redundancy variant between bearing body 2 and additional component 3, defining a labyrinth seal.
- 2nd redundancy variant possibly as a primary solution and / or as a rationalization of the 1st redundancy variant between bearing body 2 and additional component 3, defining a labyrinth seal.
- 2nd redundancy variant possibly as a primary solution and / or as a rationalization of the 1st redundancy variant between bearing body 2 and additional component 3, defining a labyrinth seal.
- a labyrinth arrangement is placed laterally next to one or more elasto arrangement (s)
