Problems solved by technology

However, when the car is running, the vibration of the car body is large, and the hook is usually made of metal material. The direct contact between the hook and the exhaust pipe makes the collision between the two large, especially when the vibration is severe, it may even cause the exhaust pipe to fall off, thereby affecting exhaust performance

Embodiment 1

[0021] The hanging device of the automobile exhaust pipe is fixed on the bottom of the automobile chassis, and mainly consists of an upper hook 1, a lower hook 2 and a strip lifting lug 4 that connects the upper and lower hooks 1 and 2 together.

[0022] Such as figure 1 As shown, both the upper hook 1 and the lower hook 2 are L-shaped by the supporting section and the connecting section, and the two supporting sections 1b, 2b are arranged vertically, wherein the supporting section 1b of the upper hook is fixed to the chassis of the car, and the supporting section 1b of the lower hook is fixed to the chassis of the car. Section 2b directly supports the exhaust pipe in the automobile exhaust system 3; the two connecting sections 1c, 2c are arranged horizontally, and the lifting lug 4 is made of rubber material, and its upper and lower ends are connected with the two connecting sections 1c, 2c Correspondingly connected, in order to prevent the lug 4 from detaching from the two c...

Embodiment 2

[0026] The structure of this embodiment is basically the same as that of Embodiment 1, and the only difference lies in the structure for laterally limiting the lifting lug 4 . The limiting structure on the connecting section of the upper hook and the lower hook is the same, such as figure 2 , image 3 As shown, on the connecting sections 1c and 2c of the upper hook and the lower hook, there are slide grooves 1e and 2e arranged horizontally and penetrating up and down. Among them, the pressing part 6a is disc-shaped, which is sleeved on the connecting section and abuts against the lifting ear 4. The convex part 6b is arranged at the inner end of the pressing part 6a and is integrated with the pressing part 6a. The convex part 6b passes through The bolt 7 and the nut 2 8 are fixed on the connection section, wherein the bolt 7 passes through the chute on the convex part 6b and the connection section at the same time, the head of the bolt 7 is against the convex part 6b, and the...

Abstract

The invention provides a hanging device of an automobile exhaust pipe, belonging to the automobile field. The hanging device solves the technical problem that the existing automobile adopts a single hanger to support an exhaust pipe to cause large vibration and dropping of the exhaust pipe so as to affect exhausting performance. In the invention, the hanging device of the automobile exhaust pipe is fixedly arranged on the bottom of the automobile chassis and comprises an upper hanger and a lower hanger, wherein, the upper hanger can be fixed with the automobile chassis, and the lower hanger can be movably connected with the automobile exhaust pipe. The hanging device of the automobile exhaust pipe is characterized in that the upper hanger and the lower hanger are connected by a lifting lug made of a rubber material, the lifting lug is in a strip shape, and the upper hanger and the lower hanger respectively pass through the upper end part and the lower end part of the lifting lug. The connecting pieces (1c, 2c) of the upper hanger and the lower hanger are provided with transverse arranged spouts (1e, 2e) in order to adjust the locating part of the lifting lug. The hanging device is composed of the upper hanger, the lower hanger and the lifting lug which causes two hangers to be connected, wherein, the lifting lug made of the rubber material can greatly prevent vibration of the automobile chassis from transmitting to the exhaust pipe so as to ensure reliable operation of an exhaust system.

Description

technical field [0001] The invention relates to an automobile exhaust pipe, in particular to a hanging device for an automobile exhaust pipe, and belongs to the field of automobiles. Background technique [0002] The exhaust system of a car is an important assembly for exhaust gas and noise reduction. It is mainly composed of exhaust pipes, catalytic purifiers, mufflers and tailpipes. It is collected in a cylinder, cleaned (through the three-way catalytic converter), and silenced, and then led to the rear of the vehicle for emission. [0003] In order to facilitate the replacement and maintenance of the exhaust system, the existing automobile exhaust system generally uses a plurality of hooks to be fixed on the bottom of the vehicle body. The hook supports the exhaust pipe, and if the exhaust system needs to be replaced or repaired, the entire exhaust system can be removed from the hook. However, when the car is running, the vibration of the car body is large, and the hook...
