Definitions
- the invention relates to a shaft brake disk in particular for a rail vehicle according to the preamble of claim 1.
- the shaft brake disc To connect a shaft brake disc to a vehicle-side hub o- the shaft of a rail vehicle retaining tabs are formed on an inner circumference of the shaft brake disk, which are also connected to two parallel and spaced apart friction rings, such as support elements, which connect the two friction rings together.
- the shaft brake disc is designed as a casting, so that the retaining tabs and the support elements are molded during casting.
- the support elements which also extend at a distance from each other, not only serve to connect the two friction rings with each other, but form
- Cooling elements to dissipate the generated during a braking friction heat can be different, round, non-round or angular.
- excitation of natural frequencies can occur which lead to a bending line course which extends over the center of the brake disk and which leads to considerable loads on the brake disk.
- continuous operation can be caused by the excitation of frequencies near or equal to the natural frequency, a noise of the lining / disc combination, the brake disc then acts in the sense of a generated speaker.
- the generated sounds can sometimes be very loud and uncomfortable and limit the comfort significantly.
- the indicated danger means unacceptable safety risk, but at least a shorter life than it would be by the pure abrasion of the friction rings.
- the invention has for its object to further develop a shaft brake disk of the generic type so that it is improved with low design and manufacturing effort in their reliability and increased in their life.
- a shaft brake disk with the features of claim 1.
- the inventive design of the shaft brake disk according to which the number of retaining tabs and / or the support elements of a prime number, prevents a bending line course over the center of the shaft brake disk. This also significantly improves the overall comfort characteristics of the brake.
- the invention provides an asymmetrical number of retaining tabs, a tendency to form natural frequencies is effectively suppressed, and in bending modes, the friction discs are forced to support themselves against the retaining tabs instead of tilting them.
- a monobloc brake disc which has no retaining tabs and in which only the support elements are arranged according to the invention.
- the retaining tabs are arranged at the same angular distance from each other, wherein the number is greater than two.
- the number of retaining tabs within the primes crowd is freely selectable, but limited by the technical feasible and meaningful.
- a number of 13 retaining tabs has been shown, which are each connected in a conventional manner to the mutually facing inner sides of the friction rings and project into the limited by the inner circumference of the interior, more or less in the sense of a toothing.
- two support elements each are arranged between two retaining tabs, which are positioned on a first, inner circular path and are assigned to the radially outer edge region of the retaining tabs.
- Circular tracks lying support elements are each present in a number of 29.
- the number of support elements per circumferential row is variable. It is only important that the respective number is equal to a prime number.
- the new shaft brake disk can be produced cost-neutral, being, as before, designed as a cast part.
- the retaining tabs may correspond in shape to the known, that is, they are formed block-like and protrude quasi as a toothing radially inwardly beyond the friction ring pairing.
- Figure 1 is a shaft brake disc according to the invention in a perspective view
- Figure 2 is a sectional plan view of the shaft brake disc.
- a shaft brake disc 1 is shown for a rail vehicle having two parallel and spaced apart friction rings 2. These friction rings 2 are connected to one another by a plurality of support elements 4 and likewise cast onto the friction rings 2, such as retaining lugs 3, which serve to connect to a vehicle-side hub or shaft (not shown).
- These retaining tabs 3 project radially inwardly toward the center axis of the shaft brake disk and protrude beyond an inner circumference 8 of the friction rings 2.
- the support elements 4 are arranged on several concentric circular paths 6 each with the same angular distance from each other. According to the invention, the number of retaining tabs 3 and arranged on at least one concentric circular path 6 supporting elements 4 corresponds to a prime number.
- these are a total of three rows, while on an inner circular path 7, which extends approximately in the head region of the retaining tabs 3, a different number of support elements 4 is arranged, in the example between two retaining tabs 3 two support elements.
- the illustrated shaft brake disk 13 has retaining tabs 3, while the support elements 4 arranged in four outer concentric circular tracks 6 are each provided in a number of 29.
- the support elements 4 are pin-shaped, that is formed with a round cross-section, with her coat in the broadest sense has the shape of an hourglass. However, this shape is only to be seen as an example. Also conceivable are other cross-sectional shapes such as oval, triangular or with rounded edges and other spatial forms.
- the number of support elements 4 on the respective circular paths 6 can vary, but always corresponding to the number of prime numbers. As shown, the support elements 4 on adjacent circular paths 6 in the circumferential direction offset from each other, preferably in each case by half a distance between two support elements 4 a circular path 6. Also on the inner circular path 7, in contrast to the example shown, a number of support elements 4th be provided, which corresponds to a prime number.
