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 The invention relates to a tuning muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles, mainly in exhaust systems of motorcycles and quads for sound improvement.

was standing The technology is that the original exhaust systems owners only dissatisfied sound results / exhaust noises deliver and they are ultimately forced to use very expensive accessory exhaust systems to buy for 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.

Of the Invention is based on the object, a Tuningendschalldämpfereinsatz with an invisible manual adjustment unit for an exhaust of motorized vehicles, mainly in exhaust systems of motorcycles and quads, for sound improvement to develop in a structurally simple way to solve and for a cost-effective production technology To create a concept.

Of the To be used with Tuning muffler insert a non-visible manual adjustment unit for a Exhaust of motorized vehicles, can be with any exhaust system be applied, in which one or more muffler inserts are installed. Also, the invention in open exhaust systems without or installed with silencer insert to the noise emission to reduce or regulate. It does not matter if the one to be protected Tuning muffler insert with a not visible manual adjustment unit for an exhaust of motorized Vehicles by riveting, welding, screwing, soldering or other connection is attached to the exhaust, the function is always preserved.

The Task is according to the invention by the features of claims 1 to 3 solved.

additional Features of the invention are given in the Unterschprüchen.

The to be protected sound solution and its components result from 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 anti-vibration silencer 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 rear 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 protective technology are both the simple ones and cost cheap construction of steel, aluminum or other material as well as the already mentioned for the user external access to the sound / sound to adapt quickly and as needed and their change optically not conspicuous.

The Principle of the protective Tuningschalldämpfereinsatz to be protected with an invisible manual adjustment unit for an exhaust of motorized vehicles is simple and yet very effective for the user.
