Definitions

• the invention relates to a brake disc assembly for vehicle wheels comprising at least one friction ring and a parallel to the friction ring trained Radbefestists Suite, wherein the friction ring and the Radbefest Whiles Suite are integrally formed from a cast material and wherein between the friction ring and the Radbefest Whiles Suite connecting webs are formed.
• the disc brake In vehicle construction, to reduce the kinetic energy of the vehicle, disc brakes are used in different designs.
• the disc brake consists of at least one disc or a friction ring and the associated brake shoes and is usually installed between the wheel and the wheel bearing.
• the braking device With the driven wheels, the braking device can be combined with the wheel carrier.
• the friction between friction rings and brake shoes converts the kinetic energy into thermal energy.
• the friction rings can reach very high temperatures up to about 850 0 C. Under the influence of the peripheral speed and the temperature, the friction rings can deform plate-like, because they are connected only on the inside of the ring with the wheel.
• the deformations make the friction rings uneven, which is often made audible by unpleasant brake noises. It is desirable to reduce this braking noise or make it inaudible. In addition, the deformations lead to uneven wear of the brake pads.
• a generic brake disc assembly is known.
• the arrangement consists of two parallel and spaced apart friction rings. Concentric with the friction rings, a carrier part is arranged.
• the support member is cup-shaped and includes a mounting portion for the wheel or the fig and a receiving area for receiving the wheel bearing.
• the carrier part is over webs with the friction rings connected.
• the carrier part, the webs and the friction rings are made of one piece.
• the one end of the web is connected to the radial bearing receiving area and the other end is connected to at least two ribs which are arranged radially extending between the friction rings.
• the middle region of the web runs at an angle ⁇ to the plane of the friction ring. The angle ⁇ should be calculated based on the load during braking.
• a brake disk arrangement for vehicle wheels comprising at least one friction ring and a wheel mounting region running parallel to the friction ring, the friction ring and the wheel mounting region being integrally formed from a cast material and connecting webs being formed between the friction ring and the wheel mounting region, the connecting webs being in Radial and / or axial direction are resiliently formed.
• the brake disk arrangement has the greatest possible range of motion during the braking process. This is achieved in that the connecting webs have a wave-shaped profile, wherein the connecting webs in the axial direction at least pass through a complete wavelength.
• the brake disc assembly is constructed as compact as possible. This is achieved in that the connecting webs with one end on the rear friction ring seen from the Radbefest Trents Victoria is arranged connected.
• FIG. 2 shows a perspective view on a partial region of a further brake disk arrangement according to the invention
• FIG. 3 shows a section through a partial region of the brake disk arrangement of FIG. 2,
• FIG. 4 shows a perspective view on a partial region of a further brake disk arrangement according to the invention
• FIG. 5 shows a section through a partial region of the brake disk arrangement of FIG. 4,
• Figure 6 is a perspective view of a portion of a further inventive disc brake assembly
• FIG. 7 shows a section through a partial region of the brake disk arrangement of FIG. 6.
• FIG. 1 schematically shows a brake disk arrangement 1 for vehicle wheels.
• the brake disk assembly 1 consists of two friction rings 2,3, which are formed as parallel annular discs and are connected by ribs 4 with each other. On the outside of the friction rings 2,3 act at each braking process, the brake shoes with the brake pads, not shown here are a. Between the ribs 4 large passage openings 5 are released. This ensures that the space between the friction rings 2,3 remains largely free for the air, which can flow from inside to outside through the passage openings 5.
• the friction rings 2,3 can be cooled after each braking both on the outside and on the inside.
• connecting webs 6 serve to connect the friction rings 2, 3 to a wheel mounting region 7 for the vehicle wheel, which is likewise not shown here.
• the wheel mounting portion 7 may be formed as a flange having holes for the wheel mounting bolts.
• a hub or a region for receiving the wheel bearing can also be formed between the wheel fastening region 7 and the connecting webs 6. The wheel bearing receiving area then extends parallel to the wheel axle and the wheel mounting portion 7 perpendicular thereto, i. parallel to the braking surfaces of the friction rings 2,3.
• the wheel mounting portion 7, the wheel bearing receiving portion, the connecting webs 6 and the friction rings 2, 3 are manufactured as a cast molding. Between the connecting webs 6 gaps 8 are visible. In Figure 1 it can be seen that the gaps 8 have a width s, which is about the same width as the width b of the connecting webs 6.
• the connecting webs 6 have a wave-shaped profile. In Figure 1, seen in the axial direction, the connecting webs 6 pass through two complete wavelengths.
• the connecting webs 6 have alternately bulges 9, 10. On an outwardly directed bulge 9 follows in each case an inwardly directed bulge 10. If the wave-shaped profile as shown in Figure 1 passes two full wavelengths, two bulges 9 are formed on the connecting webs 6 each outwardly and two bulges 10 to the inside. There are also wavy profiles with several completely traversed wavelengths or with less than a length of time conceivable.
• FIG. 2 and FIG. 3 show a further exemplary embodiment of the brake disk arrangement 1 according to the invention.
• the intermediate spaces 8 between the connecting webs 6 have a substantially smaller width s than in FIG. 1.
• the connecting webs 6 have a width b which is at least twice as large as the width s of the interspaces 8.
• FIG. 2 shows how the intermediate spaces 8 similar to slots are formed.
• slots 8 can be formed, which can have a width s of a few millimeters.
• the slot-shaped intermediate spaces 8 and the connecting webs 6 are formed here, for example, helical.
• the spiral course of the slots 8 is especially well visible in the first part of the connecting webs 6, which is arranged in the flat area directly adjacent to the Radbefest Trents Society 7. This ensures that the connecting webs 6 are as stiff as possible and undeformable when the wheel is loaded during braking in the direction of rotation of the wheel. At the same time, it is also achieved that the connecting webs 6 allow an elastic, flexurally soft deformation in the direction of the expansion, which is a consequence of the temperature increase of the friction rings 2, 3.
• the slots 8 can also be formed radially or tangentially.
• FIGS. 4 and 5 show a further variant of the brake disk arrangement according to the invention.
• the difference from the variant of Figures 2 and 3 is the connection of the connecting webs 6 at the rearmost lying, ie the inner friction ring 3.
• FIGS. 6 and 7 show a further exemplary embodiment of the brake disk arrangement 1.
• the connecting webs 6 are arranged alternately connected both to the outer friction ring 2 and to the inner friction ring 3.
• a parallelogram is produced so that a parallel displacement of the friction rings 2, 3 to the outside is made possible under thermal stress.
• a plate-like deformation of the friction rings 2,3 is prevented.
• the design and arrangement of the connecting webs 6 can be adapted to the mechanical and thermal stresses expected in the braking operations.
• the brake disk assembly 1 can be adapted to all types of vehicle wheels, such as wheels of trucks, passenger cars, motorcycles, railway cars or aircraft.
