Definitions

  • the invention is based on a disc or drum brake and relates to the problem of suppressing noise emanating from the brake, in particular squeaking.
  • Brake squeaking is particularly uncomfortable. For this reason, numerous measures have been proposed and some have been put into practice which are intended to prevent disturbing noise from the brake, either by damping oscillating brake parts or by detuning their natural frequencies so that they lie in the inaudible range or are no longer excited.
  • the aim of the invention is therefore to tackle the problem of suppressing braking noises somewhat more systematically and to find a generally usable, effective and reliable solution.
  • the starting point of the solution is the observation that particularly large oscillation amplitudes (antinodes) occur at certain points on the brake, especially on the brake disc or brake drum, which cause loud braking noises and can therefore be combated most effectively here.
  • the noise damping takes place on the friction surface of the noise damper, which is constantly in contact with the brake, in that vibration energy is converted into frictional heat.
  • An advantage is the versatility of the invention, which is not limited to a particular type of brake, but can be used both in disc and drum brakes of various types. Compared to known devices, it is characterized by the consequence of also applying vibrations to rotating parts of the brake. dampen where they occur preferentially. If the circumstances so require, several silencers can be used.
  • the noise damper is adjustable. In this way, its friction surface can be set to a point of maximum vibration amplitude and its effectiveness can be individually optimized. If the properties of the brake change over time, the process can be repeated.
  • claim 3 can be advantageously used that large areas of the brake disc or brake drum are easily accessible.
  • the point to be damped can be selected relatively freely according to practicality, without the noise damper and other brake parts interfering with one another. In this way, its effectiveness is further increased and remains more reliably maintained, which is particularly important in stubborn cases of brake squeal.
  • the noise damper according to claim 4 has a resilient element which generates the force for pressing its friction surface against the brake.
  • the pressing force is adjustable, further possibilities open up for individually optimizing the damping at any time.
  • an embodiment according to claim 7 is more favorable in which the friction surface has a friction lining.
  • the invention can be further improved if the noise damper according to claim 8 is anchored to a vehicle part to which essentially no vibrations of the brake are transmitted which could impair the effectiveness of the damping.
  • the noise damper can also be advantageously used on stationary brake parts that tend to vibrate, for example according to claim 9 on the brake caliper of a disc brake.
  • sic recommends an embodiment according to claim 10.
  • the muffler is attached directly to the brake here, so that the muffled brake can be installed as a pre-assembled unit on the vehicle.
  • An additional dimension rests resiliently on the brake housing and, due to its inertia, enables a rubbing relative movement between the contact surface of the silencer and the brake housing.
  • the silencer is attached to a guide pin of a floating caliper partial brake disc brake.
  • This attachment only requires a modified guide pin, while the brake housing of a current series can otherwise be taken over unchanged. This saves tool costs. It is also possible to retrofit conventional brakes with the noise damper according to the invention. Further advantageous design features are disclosed in subclaims 12 and 13.
  • FIG. 1 is a side view of a schematically shown disc brake with silencers
  • Fig. 3 is a partially sectioned side view of a floating caliper brake pad with a noise damper according to the invention in a further embodiment.
  • the first example relates to a disc brake, the essential components, namely brake disc 1, brake shoes 2, 3 and brake caliper 4 in FIG. 1 schematically are shown.
  • the silencers 5 and 6 consist of friction lining 8, leaf spring 9 and anchoring 10, by means of which they are connected to the wheel suspension of the vehicle.
  • the friction lining 8 is positioned so that it presses against a point on the brake disc 1 that tends to large vibration amplitudes and suppresses them. Due to its position, noise damper 5 is particularly well suited for damping axial, noise damper 6 for damping radial or tangential vibrations of brake disc 1.
  • the friction surface 11 is made of steel and is simply formed by the free end of the leaf spring 12. Its anchor 13 is also connected to the wheel suspension. The friction surface 11 presses on a point of the brake caliper at which large vibration amplitudes occur, which are damped in this way.
  • a partial lining disk brake has a floating caliper 101 with a brake piston 102 and two brake shoes 103, 104, which are intended to be pressed against a brake disk 105.
  • the floating caliper 101 is slidably guided on a brake carrier 106 by means of two bolt guides.
  • One of the two bolt guides can be seen in the drawing.
  • a thread 108 of a guide bolt 109 is screwed into a threaded bore 107 of the brake carrier 106, on which a bushing eye 110 connected to the floating caliper 101, which is provided with a bushing 111 made of elastic material, slides.
  • the guide pin 109 is provided on its end section facing away from the brake carrier 106 with a circumferential annular groove 112, in which the one end 117 of a wire spring 113 belonging to a noise damper 114 is clamped.
  • the silencer 114 also includes an additional mass 115 with a cylindrical base body which merges into a cone 119 on one axial side and has a cylindrical projection 116 on its other axial side, around which the other end 118 of the torsion spring 113 is wound.
  • the guide pin 109 has an axial opening 120 with hexagonal in its end portion Cross-section that was originally intended to hold a wrench.
  • the additional mass 115 is now pressed axially against the end of the guide bolt 109 by means of the spring 113, so that the tip of the cone 119 extends into the opening 120 and the cone jacket lies against the outer edge of the opening 120.
  • This simple fastening allows, on the one hand, relative movements between the brake and additional mass 115 and, on the other hand, prevents the additional mass 115 from falling out.

Abstract

L'invention concerne des freins à disque ou à tambour et vise à supprimer les bruits des freins, notamment leur couinement. L'objet de l'invention est par conséquent un dispositif particulièrement efficace et fiable d'élimination des bruits des freins. A cet effet, au moins un amortisseur stationnaire de bruit (5, 6) est en contact, par frottement, avec le disque (1) ou le tambour en rotation du frein et amortit ses vibrations. L'invention se distingue des mesures connues par des possibilités multiples d'utilisation. Elle ne se limite pas à un type particulier de freins et permet d'optimiser individuellement les propriétés d'amortissement. L'amortisseur de bruit (7) peut être avantageusement utilisé également pour amortir les bruits de parties stationnaires des freins. Dans un autre mode de réalisation, un ressort (113) est assujetti au carter du frein, porte une masse supplémentaire (115) de dimensions réduites et presse cette masse supplémentaire (115) contre les freins.
