A holding device for retaining an exhaust pipe of an exhaust system with a mounted supporting device includes a carrying portion for accommodating the supporting device, and a fastening portion for fastening the holding device to a vehicle. In an embodiment, the fastening portion has a spring member with a snap-in hook for forming a snap-in connection.

A sound generation assembly unit, for an exhaust system of an internal combustion engine, includes a sound generation module (16) with a sound generation module housing to be arranged at an exhaust gas guide element (12) of the exhaust system (14). At least one loudspeaker unit (20) is arranged in the sound generation module housing (18). A rear volume module (30) includes a rear volume module housing (32) and a rear volume (34) formed in the rear volume module housing (32). The rear volume module housing (32) is connected or can be connected to the sound generation module housing (18) for the acoustic coupling of the rear volume (34) to the at least one loudspeaker unit (20).

A system and method including a non-metallic shell to prevent debris from contacting a component of an exhaust system is disclosed. The shell may be formed from silicone. The shell may also form part of an assembly including a metallic corrugated body, which may be positioned between two pipe sections of the exhaust system. The shell may be separate from an exhaust coupler and be secured separately to the two pipe sections connected to the exhaust coupler.

An isolator is disclosed for attaching an exhaust system to a frame pin on a vehicle frame. The isolator includes a vibration damping body that defines a frame pin receiving opening and an exhaust pin receiving opening. A tab is provided on an upper end of the vibration damping body that is manually engaged to bend the upper end of the body away from and toward the frame pin to facilitate inserting the frame pin in the frame pin receiving opening.

The present invention relates to an elastic support for a load, with at least one elastomer body; the at least one elastomer body has at least one spring section and at least two receiving openings for receiving fastening elements; the spring section has at least one reinforcement; at least one of the two receiving openings is positioned outside of the reinforcement of the at least one spring section; and at least one of the two receiving openings is associated with at least one reinforcement that surrounds the respective receiving opening and is connected to the reinforcement of the spring section.

An immersion heater including an encapsulated, semi-conductive, heating element. The heating element may be a non-metallic, carbon-based material in the form of a monofilament, a yarn or bundle of semi-conductive fibers which may be twisted, braided fibers or yarns, or the like. The encapsulation may be in the form of a tube of one or more layers of encapsulation material(s) with the heating element inserted therein. Alternately, the heating element may be thermoplastic with semi-conductive carbon additive, and the heating element may be coated with one or more external layers of insulating encapsulation material(s). The encapsulation material may be a rubber or thermoplastic material with sufficient chemical resistance to be immersed in a reservoir of fluid subject to freezing or thickening at low temperatures, such as DEF. The heater may be thermoformed into a predetermined fixed shape.

An isolator in an exhaust system of a vehicle is provided. The isolator comprises a bracket to be connected with an under body of the vehicle; and a gas filled cushion at least partially embedded in the bracket. The cushion is formed to have a through hole in a middle portion and the through hole is configured to receive a hanger connected to an exhaust system.

A suction tube for a urea sensor installed in a urea tank comprises a suction pipe and a cover. The suction pipe has a suction opening and a hole extending through a wall of the suction pipe. The cover is disposed on an outside of the suction pipe and covers the hole. When there is an under-pressure in the suction pipe compared to the urea tank, the cover abuts the suction pipe and seals the hole. When there is an overpressure in the suction pipe compared to the urea tank, the cover deforms and allows an excess urea solution to escape through the hole and flow back into the urea tank.

The present disclosure relates to an isolator assembly for supporting an exhaust component from a structural portion of a vehicle. The isolator assembly has a mounting bracket having a pair of spaced apart rings defining a mounting bore. An elastomer shear hub component is disposed within the mounting bracket and has an outer diameter (OD) shear hub extending between the pair of spaced apart rings, and an inner diameter (ID) shear hub disposed within the OD shear hub. The ID shear hub defines a central mounting bore adapted to receive an external hanger component.
