Abstract

Tuning muffler insert with a non-visible manual adjustment unit for an exhaust of motorized vehicles, mainly for installation in exhaust systems of motorcycles and quads for sound enhancement, characterized by a resonance tube (13) having at least one sound radiation input (8.0, 8.1) and at least one sound emission outlet (9) to the resonance tube beginning (14) has a plugged adjuster (16) has at least one Schallabstrahlungseingang (8.0, 8.1) and over at least two 90 degrees bent inwardly to the center of the Verstellers (16) pointing locking tab (18) has.

Description

The invention relates to a Tuneingschaltdämpfereinsatz with a non-visible manual adjustment for an exhaust of motorized vehicles, mainly in exhaust systems of motorcycles and quads for sound improvement.

The state of the art is that the original exhaust systems provide the owners only dissatisfied sound results / exhaust noises and they are ultimately forced to buy very expensive accessory exhaust systems to achieve a good sound improvement.

From the DE 20 2006 014 137 U1 2007.01.25 a manually adjustable muffler insert is known, which serves to change the sound of exhaust systems. The disadvantage here, however, is that the system is visually striking.

The invention has for its object to develop a Tuningendschalldämpfereinsatz with a non-visible manual adjustment for an exhaust of motor vehicles, mainly in exhaust systems of motorcycles and quads to improve sound in a structurally simple way and to create a manufacturing technology cost-effective concept.

The protective anti-vibration muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles, can be used with any exhaust system where one or more muffler inserts are installed. The invention can also be installed in open exhaust systems with or without muffler insert to reduce or regulate the noise emission. It does not matter whether the protective muffler insert to be protected is attached to the exhaust with a non-visible manual adjustment unit for an exhaust of motorized vehicles by riveting, welding, screwing, soldering or other connection, the function is always maintained.

The object is achieved by the features of claims 1 to 3. Additional features of the invention are set forth in the subclaims.

The sound solution to be protected and its components are shown in the drawings 1-4.

Mainly the invention is characterized by the fact that visually the change is not detectable, since the baffle plate used ( 10 ) So the appearance of the exhaust system is maintained and causes the sound change by external access by means of an adjustment inside the exhaust system via a pivot mechanism.

The protective anti-vibration muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles is located at the exhaust end and is mainly exchanged for the original muffler insert. The Tuning muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles is manually by means of adjusting the sound adjustment in the resonance tube ( 13 ) and in the locking tabs ( 18 ) of the Verstellers ( 16 ) opens / locks via a pivoting direction ( 19 ) clockwise (sound increase) or counterclockwise (sound reduction) or vice versa. By pivoting the Verstellers ( 16 ) in the pivoting direction ( 19 ) clockwise or counterclockwise minimizes or increases the back pressure of the exhaust gases. The larger the passage of the rectangular sound radiation input ( 8.0 . 8.1 ), the louder becomes the exhaust noise and the smaller the passage of the rectangular sound radiation input ( 8.0 . 8.1 ), the quieter the exhaust noise. The exhaust gases are in the last cycle in the last bounce chamber ( 3 ) on the baffle plate ( 10 ) then at the baffle wall ( 20 ) before it is reflected by the sound radiation input ( 8.0 . 8.1 ) via the resonance tube ( 13 ) to the sound emission output ( 9 ). The locking tabs ( 18 ) serve as a stop, so that they have a maximum and a minimum of sound radiation input ( 8.0 . 8.1 ) and accidentally completely close the sound emission input ( 8.0 . 8.1 ) prevent.

The baffle plate ( 10 ) is fixed to the resonance tube ( 13 ) fastened by riveting, screwing, soldering, welding or other connection and it is all possible from a rotating part z. B .: CNC milling, etc. manufacture so that can be dispensed with the aforementioned mounting options. The attachment points ( 11 ) are used to hold the exhaust securely by riveting, screwing, soldering, welding or other connections.

The advantages of the technology to be protected are both the simple and inexpensive construction made of steel, aluminum or other material as well as the already mentioned for the user external access to the sound / sound quickly and adapted to demand and their change is visually not conspicuous.

The principle of the protective Tuning muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles is simple and yet very effective for the user.
