Abstract

Tuning muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles, mainly for installation in exhaust systems of motorcycles and quads to improve the sound, characterized by a resonance pipe (13) which has at least one sound emission inlet (8.0,8.1) and at least one sound emission outlet (9). For this purpose, an adjuster (16) is attached to the beginning (14) of the resonance tube, which has at least one sound emission input (8.0, 8.1) and has at least two locking tabs (18) bent at 90 degrees and pointing inwards towards the center point of the adjuster (16).

Description

The invention relates to a tuning muffler insert with a manual adjustment unit (not visible) for an exhaust of motorized vehicles, mainly in exhaust systems of motorcycles and quads to improve the sound.

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

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

The object of the invention is to develop a tuning muffler insert with an invisible manual adjustment unit for an exhaust of motorized vehicles, mainly in exhaust systems of motorcycles and quads, to improve the sound in a structurally simple manner and to create a concept that is cost-effective in terms of production technology.

The protective tuning rear silencer insert with an invisible manual adjustment unit for an exhaust from motorized vehicles can be used with any exhaust system in which one or more rear silencer inserts are installed. The invention can also be installed in open exhaust systems with or without a silencer insert in order to reduce or regulate noise emissions. It does not matter whether the tuning rear silencer 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 retained.

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

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

The main feature of the invention is that the change cannot be detected visually, since the baffle plate (10) used retains the look of the exhaust system and causes the change in sound through external access using an adjustment aid inside the exhaust system via a swivel mechanism.

The protective tuning rear silencer insert with a non-visible manual adjustment unit for an exhaust from motorized vehicles is located at the exhaust end and is mainly exchanged for the original rear silencer insert. The tuning muffler insert with a non-visible manual adjustment unit for an exhaust from motorized vehicles is manually adjusted using an adjustment aid that is inserted into the resonance pipe (13) to adjust the sound and ends/locks in the locking tabs (18) of the adjuster (16) via a pivoting direction (19 ) clockwise (noise increase) or counterclockwise (noise reduction) or vice versa. By pivoting the adjuster (16) in the pivoting direction (19) clockwise or counterclockwise, the dynamic pressure of the exhaust gases is minimized or increased. The larger the passage of the rectangular sound radiation entrance (8.0,8.1), the louder the exhaust noise and the smaller the passage of the rectangular sound radiation entrance (8.0,8.1), the quieter the exhaust noise. In the last cycle, the exhaust gases are reflected in the last baffle chamber (3) on the baffle plate (10) and then on the baffle wall (20) before they are conducted through the sound emission inlet (8.0,8.1) via the resonance tube (13) to the sound emission outlet (9). . The locking tabs (18) also serve as a stop so that they ensure a maximum and a minimum of the sound emission input (8.0,8.1) and prevent the sound emission input (8.0,8.1) from being completely closed unintentionally.

The baffle plate (10) is firmly attached to the resonance tube (13) by riveting, screwing, soldering, welding or some other connection Mounting options can be omitted. The attachment points (11) are used for secure attachment to the exhaust using rivets, screws, 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 and the already mentioned external access for the user to adjust the sound quickly and as required and the change of which is not visually noticeable.

The principle of the protective tuning rear silencer insert with a non-visible manual adjustment unit for an exhaust from motorized vehicles is simple yet very effective for the user.
