Embodiment Construction

[0039] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0041] like Figure 1-Figure 6 As shown, the lifting lug 100 for the exhaust system of a vehicle (not shown in the figure) according to the embodiment of the present invention includes: a connecting rod 10 and a body 20 . It should be noted that the exhaust system of the vehicle includes an exhaust pipe 220 , and the lifting lug 100 is connected between the exhaust pipe 220 and the floor 210 of the vehicle.

[0042] Specifically, the lifting ear 100 has two symmetrically arranged bodies 20 , and an opening 21 is formed in each body 20 through its thickness. Both ends of the connecting rod 10 respectively pass through the side walls of the corresponding opening 21 and protrude into the ...

Abstract

The invention provides a lifting lug for an automobile exhaust system and a vehicle with lifting lugs. The lifting lug for the automobile exhaust system comprises a connecting rod and two symmetrically arranged bodies, wherein an opening is formed in each body, and penetrates through the thickness of the body; the two ends of the connecting rod penetrate through the sidewalls of the corresponding openings, and extend into the openings respectively; at least one of the two bodies can rotate relative to the connecting rod. According to the lifting lug for the automobile exhaust system, the two bodies are arranged on the connecting rod, and at least one of the two bodies can rotate relative to the rotating rod, then the body capable of rotating relative to the connecting rod can bear higher torque when the lifting lug is twisted due to improper assembly or generated non-directional excitation energy of an exhaust pipe of the exhaust system, the probability of lifting lug failure and even tearing caused by stress concentration is further lowered, and the vibration of the exhaust pipe is reduced, so that the NVH (noise vibration and harshness) properties of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a lifting lug for a vehicle exhaust system and a vehicle with the same. Background technique [0002] As the load-bearing and vibration-isolation part of the exhaust system, the lifting lug plays the role of suspending the exhaust system and isolating the excitation from the exhaust system from the body. Most of the exhaust lugs used by vehicles in the related art are made of rubber. There are pivot pin holes at both ends of a rubber body, which are used to connect the pivot pins on the exhaust pipe with the pivot pins on the automobile floor, so that The exhaust pipe hangs to the floor. The main technical requirements of the lifting lug are the strength, temperature resistance, durability and dynamic stiffness of the lifting lug. In order to meet the above performance requirements, most of the existing technologies achieve the purpose by changing the material of the liftin...
