In order to reduce torsional vibrations and wheel slip in a wheel set for a rail vehicle the wheel set comprising a pair of wheels connected by an axle is provided with a vibration absorbing device comprising a mass, resiliently mounted on the wheel set and adapted to oscillate at the resonant frequency of torsional vibrations of the wheel/axle system. A method of preventing or reducing torsional vibrations in a wheel set of a rail vehicle is also disclosed, the method comprising determining the resonant frequency of torsional vibrations of the wheel/axle system and resiliently mounting a vibration absorbing device in the form of a mass, on the wheel set, the mass and its resilient mounting being selected to oscillate at or near that resonant frequency.

Brake noise (unpleasant squealing noise) caused when applying a brake is effectively reduced. A weight is mounted via an elastic body on a vibrating member (brake pad, piston, caliper) of a disc brake for applying a brake force by holding a disc rotor from the sides thereof with two brake pads. The weight vibrates on receiving vibration from the brake pads because the weight is mounted on the vibrating member via the elastic body. The vibration of the weight has a low frequency and its phase is the same as that of the vibration of a brake pad. However, as the vibration frequency of a brake pad increases, the vibration phase of the weight starts to deviate from the vibration phase of a brake pad accordingly. The phase difference becomes almost 180 degrees when the frequency becomes close to or greater than a certain frequency. The vibration of a brake pad can be suppressed by the vibration of the weight by matching the certain frequency to the frequency of the brake squeal. It is possible to reduce the brake squeal of a large vehicle having disc brakes of a large size to a practically sufficient level only by adding inexpensive parts, thereby making it possible to maintain its original performance even after replacing brake pads.

In order to further improve a method for producing a carrier body for a friction lining of a disk brake, in such a way that the rigid connection between a friction-lining carrier plate of the carrier body and a first damper mass of the carrier body is more robust, a force directed perpendicularly towards the first pin-shaped project is exerted, according to the invention, by means of pressing until the first pin-shaped projection is compressed to such an extent that the first pin-shaped projection forms, within the first hole, a form closure with an inner wall of the first hole in some regions.
摘要:
A pad (20) for disc brakes comprises a plate (22) acting as the support for a friction material layer (24). The plate (22) extends past the friction material layer (24) at least at a radially outer portion (E) of the pad. At least one load (30a, 30b) is applied to the plate (22) and fixed thereto by means of clinching. This load changes the mass of at least one portion of the plate such as to obtain an inertia of the pad which substantially avoids the vibrations of the pad during the braking action which are suitable to cause noisiness of the disc brake. The load (30a, 30b) comprises at least one projection (32) suitable to be clinched to fix the load to the plate. The projection (32) is inserted within a hole (34) of the plate and clinched.
