Embodiment Construction

[0019] figure 1 A brake caliper according to the invention is shown, which is designed as a stationary brake caliper. The stationary brake caliper is fixed via a bracket 1 on a vehicle axle (not shown). The caliper has four pistons 2 on each side, which during braking press against a brake pad 3 (only shown on one side), which in turn presses against a brake disc ( not shown) extrusion.

[0020] Noise is generated during braking, which is caused by the vibration of the brake. Such brake noise is undesirable. According to the invention, a connecting device 4 is provided which, in the present exemplary embodiment, is designed in the form of a rod and which tightens the two lugs 5 of the brake caliper. Due to the applied tension (or compression), the vibration characteristics of the brake caliper change. The natural frequency of the brake caliper is shifted.

[0021] The invention is particularly effective when the caliper boss protrudes relatively far from the caliper and ...

Abstract

The invention relates to a brake caliper on a brake, in particular a disc brake. The brake caliper comprises raised sections (5), embodied as plateaus (6) in the represented case. The raised sections (5) are tensioned against each other by means of a connector device (4) by the introduction of tensile or compression forces. Noises occurring on braking can thus be significantly reduced.

Description

technical field [0001] The invention relates to a brake caliper for a brake, especially a disc brake for vehicles, which has at least two mutually opposed raised portions which define a free space between them and are passed through a The connecting means of the free space are connected to each other. Background technique [0002] Brake noise is produced when the car brakes. The cause of this noise is vibrations of the braking system, which can occur over a wide frequency range. The so-called "brake squeal" that occurs at frequencies above about 1kHZ is particularly annoying. Vibrations at lower frequencies (up to 400HZ) are called "brake rumble". The latter can not only be heard but also felt through the steering wheel. [0003] Various measures have been taken in practice in order to reduce the vibrations. For example, it is known to mount counterweights on brake calipers in order to thereby increase their natural frequency. But such measures have limited effectivene...
