Abstract

(57) [Abstract] [Purpose] The present invention aims to improve vibration absorption and heat resistance of a muffler support for vehicle exhaust gas. [Structure] A metal thin leaf spring is half-wound around and connected to the outer periphery of a plurality of mesh bodies obtained by compression molding a thin metal wire having a rod insertion port, and a curved spring portion is formed in the middle of the connecting portion of the metal thin leaf spring. Muffler support for exhaust gas from vehicles.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a muffler support for elastically supporting a vehicle exhaust gas muffler on a vehicle body.

[0002]

[Prior art]

 Conventionally, as a muffler support for vehicle exhaust gas, a metal rod is simply attached to the vehicle body, or a locking rod and a body side are fixed to the exhaust system side as shown in Japanese Utility Model Laid-Open No. 3-69337. A mount rubber having a pair of mounting holes into which locking rods fixed to the exhaust system are inserted, and which is interposed between the exhaust system side and the body side to elastically support the exhaust system, A plurality of pairs of mounting holes are arranged in a single rubber member, and a through pattern groove in which the spring constant changes in the direction connecting the pair of mounting holes is provided at the center thereof. The mounted exhaust system mount mule is known.

[0003]

[Problems to be solved by the device]

 In the above conventional technique, the former had a problem in vibration absorption. In addition, the latter is a rubber product, so that there is a limit in heat resistance to support a high temperature member such as a muffler, and there is a problem in that layout is difficult.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and a thin metal leaf spring is half-wound around and connected to the outer periphery of a plurality of mesh bodies formed by compression molding a thin metal wire having a rod insertion port. A curved spring part is formed in the middle of the connection part of the thin leaf spring, and by combining the metal mesh molded body and the metal thin leaf spring, a muffler support excellent in heat resistance and vibration absorption is provided. It is a thing.

Embodiment Next, one embodiment of the present invention shown in the drawings will be described in detail. Reference numeral 1 denotes a disc-shaped mesh body which is made of a heat-resistant thin metal wire made of stainless steel or the like and knitted and compressed to a predetermined density, and which has elasticity and is highly elastic. The two mesh bodies are arranged at regular intervals, and the outer periphery of the mesh body is half-wound by the metal thin leaf spring 3, and the mesh body 1 and the metal thin leaf spring 3 are connected and fitted to each other, and the metal thin plate is attached. A curved spring portion 4 is formed between the connecting portions of the spring 3. The metal thin leaf spring 3 is fixed at one end to the mesh body 1 and the metal thin leaf spring 3 by inserting and bending one end of the metal thin leaf spring 3 into the locking hole 3a and the other end of the locking projection 3b. It may be fixed by welding or the like. When installing on the vehicle, insert the locking rod for fixed connection to the muffler into the rod insertion opening 2 of one mesh body 1, and connect the fixed rod to the vehicle body to the rod insertion opening 2 of the other mesh body 1. Insert the locking rod for.

Next, the operation will be described. The vibration transmitted from the muffler is absorbed by both the elastic mesh body 1 having a high vibration absorption property and the curved spring portion 4 of the metal thin leaf spring 3 to which the mesh body 1 is connected and fitted. Further, since the mesh body 1 and the metal thin leaf spring 3 are made of only a metal material, they are excellent in heat resistance, and do not deteriorate even under use conditions near a muffler of 200 ° C. or higher. Can maintain long-term performance.

[0007]

[Effect of device]

 According to the present invention, a thin metal leaf spring is half-wound around and connected to the outer periphery of a plurality of mesh bodies formed by compression molding thin metal wires having a rod insertion port, and a curved spring portion is provided in the middle of the connecting portion of the thin metal leaf spring. Since it is formed and integrated, it is possible to effectively absorb the vibration of the muffler by the combined structure of the elasticity of the mesh body itself and the curved spring part of the metal thin leaf spring, and both are made of only metallic material. Therefore, it has excellent heat resistance and can retain its performance for a long period of time even when it is used near a muffler that has a high temperature of 200 ° C or higher.
