Abstract
A vibrating flange assembly (100, Fig. 3) for absorbing noise and damping mechanical vibrations, comprising a flange 10; a support 20; and a flexible element 30, which could be made of cellular rubber, which is injected into a space g between flange 10 and support 20 and holds them in an assembled configuration. The flange 10, support 20, and resilient element 30 may be press-fitted to each other; and the support 20 may have a radial section (21, Fig. 2) that bends into an axial section (22, Fig. 2).
Description
Description
Vibrating flange assembly The invention relates to a vibrating flange assembly, in particular a resilient vibrating flange assembly.
Currently known vehicle braking systems comprise electro-hydraulicmodulesliketheonedescribedbyEF3119649A1, which comprises electrically controlled valves and electronic components as well. Due to the vibrations and noise produced during the braking module operation, the comfort of vehicle occupants is likely to be affected.
The technical problem is that usually the braking module is rigidly connected on the vehicle's firewall, by means of a rigid vibrating flange. Such a rigid vibrating flange is made by assembling more than three separate parts, each produced by different methods (deep drawing, casting, machining etc.), requiring lots of assembling processes which finally lead to a rather expensive product.
The objective of the present invention is to solve the deficiencies of the mentioned prior art and to provide a vibrating 25 flange assembly that reduces vibration and absorbs noise in a cost-efficient manner.
This objective is achieved according to the invention by means of the technical characteristics mentioned in the independent 30 claim.
Advantageous embodiments of the invention are mentioned by the dependent claims.
An aspect of the present invention is to provide a vibrating flange assembly comprising a flange and a support held in assembled relation by means of a resilient element injected in an interstitial gap between flange and support.
Amain advantage of a vibrating flange assembly according to the invention is that is relatively simply manufactured and assembled. Additional advantage is that, should design needs to be changed or adapted to another module, there is no need to change the whole assembly, it is sufficient to change only the support. Yet another advantage is that, when it is employed with a braking module, the operational life of afferent electronic components increases.
The invention will now be described in more detail by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a sectional view of components of an injection mould and components of the vibrating flange assembly according to the present invention; - Fig. 2 is a sectional view of a detail A from Fig. 1; - Fig. 3 is a sectional view of the vibrating flange assembly embodying the present invention, after removal of the injection mould; - Fig. 4 is a side sectional view of the vibrating flange assembly from Fig. 3 attached to a vehicle firewall.
Referring initially to Fig. 1 and 2, an initial form of the vibrating flange assembly embodying the present invention comprises a generally radial shaped flange 10 and a support 20. Flange 10 has an axially extended central bore b and threaded apertures 11 to receive screws (not shown). Support 20 has a radial section 21 which bends into an axial section 22. Both flange 10 and support 20 are rigid and made of metal (aluminium being the preferred metal, for obvious reasons).
In order to obtain the vibrating flange assembly in its final form, for injection is used a generally annular base 40 having role of support and provided with a first pin 41a and a second pin 41b. Support 20 is placed upon base 40, and rests on first pin 41a. Second pin 41b is taller than first pin 41a, and flange 10 rests on second pin 41b, thus the direct metallic contact between flange 10 and support 20 is precluded. Even more, the height difference of pins creates an interstitial gap g, into which an elastic material is injected by means of an upper part 42 of injection mould. For the ease of handling, snap fits (not figured) can be used when injecting the elastic material.
After curing, the elastic medium forms a third part of the flange assembly, namely a resilient element 30. Thus, after removal of the injection mould parts (base 40 and upper part 42), a vibrating flange assembly 100 is obtained, as it is illustrated in Fig. 3, comprising the flange 10 and the rigid support 20 which are held in assembled relation by means of the resilient element 30.
In operation, that is, in the application of the flange assembly to a piston rod subject to mechanical vibrations, an example of such a piston rod being that of an electro-hydraulic braking module (not shown), the dynamic properties of the elastic element 30 subject to both axial and radial compression are chosen so that to lower the vibrations and noise amplitude.
In this respect, the elastic material forming the resilient element is selected so that it has physical properties which provide the desired natural noise absorption. For example, cellular rubber is preferred. When force is applied on a brake pedal from the electro-hydraulic braking module attached by means of the vibrating flange assembly embodying the invention, the resilient element is subject to volumetric compression and can withstand high pressure without being damaged.
Moreover, as it is illustrated by Fig. 4, when the flange assembly is attached to a vehicle firewall 50, resilient element 30 has a sealing role, since it is in permanent contact with firewall 50.
While certain embodiments of the present invention have been described in detail, those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention as defined by the following claims.
