Problems solved by technology

[0009] The problem is that the warping of the wheel brake disc exceeds a certain size which cannot be reduced by turning the outer diameter (überdrehen) to such an extent that a flat friction surface can be achieved by screwing the wheel brake disc on

Embodiment Construction

[0044] In the following description of the drawings, terms such as upper, lower, left, right, front, rear, etc. only refer to the wheels, brake discs, outer rings, inner rings, upper pressure plates, etc. selected in the corresponding drawings. Exemplary illustrations and locations of . These terms are not to be interpreted as restrictive, which means that these references can change due to different working positions or a mirror-symmetrical design, etc.

[0045] In the method according to the invention, after determining the deviation of the friction surface of the wheel brake disk from a plane defined by the circumferential edges of the friction surface, the friction surface of the wheel brake disk is permanently restored to the surface defined by the circumference of the friction surface. in the plane defined by the edge.

[0046] As "deviation of the friction surface of the wheel brake disc from the plane determined by the circumferential edges of the friction surface", h...

Abstract

The invention relates to a method for reducing the flattening of a wheel brake disk for a rail vehicle, caused by braking processes, wherein after determining a deviation of a friction surface of thebrake disk from a plane defined by a peripheral edge of the friction surface, the friction surface of the wheel brake disk is permanently moulded back into the plane defined by the peripheral edge ofthe friction surface. The invention further relates to a device for carrying out said method.

Description

technical field [0001] The invention relates to a method for reducing the warpage (hot spot: schirmung) of a wheel brake disk for a rail vehicle that occurs as a result of the braking process. Furthermore, the invention relates to a device for carrying out such a method. Background technique [0002] Such a wheel brake disc for a rail vehicle is fastened on both sides of a rail wheel of the rail vehicle by a plurality of through bolts distributed in the circumferential direction. [0003] The wheel brake disc is held on the wheel body through a threaded connection structure. [0004] In particular during so-called emergency braking, the temperature of the wheel brake disc increases strongly, which leads to dish-shaped deformation of the brake disc. Such deformation behavior is also called warping. Such a warping of the wheel brake disc can lead to thickness fluctuations, which should be avoided as far as possible, or locally high thermal loads after a relatively long oper...
