Abstract

The invention discloses an automobile exhaust suspended structure which comprises two lifting lugs (1) and a lifting hook (2), and also comprises an installing bracket (3) used for connecting the lifting lugs (1) with the lifting hook (2), wherein the lifting lugs (1) are arranged on the installing bracket (3) which is connected with the lifting hook (2), a slot (10) used for installing the lifting lugs (1) is arranged on the installing bracket (3), the lifting lugs (1) are clamped in the slot (10), the center of each lifting lug is provided with a center hole, the lifting lugs are connected through a U-shaped pipefitting (4), two ends of the U-shaped pipefitting (4) are respectively inserted into the center holes of the lifting lugs (1), the lifting lugs (1), the installing bracket (3) and the lifting hook (2) are arranged in a V shape, and the lifting lugs (1) and the installing bracket (3) are arranged at the vertex angle of the V-shaped structure. The invention improves the mode frequency of the exhaust suspended structure and meets the requirement on automobile NVH (Noise Vibration and Harshness) performance through structure improvement.

Description

technical field [0001] The invention belongs to the field of automobile parts, and in particular relates to an automobile exhaust hanging structure. Background technique [0002] With the development of the global automobile market and increasingly fierce competition, ride comfort is becoming an important factor affecting user purchase behavior and user satisfaction. NVH, as the main aspect of ride comfort, has attracted more and more attention from major automobile manufacturers. Internal noise, vibration and external noise mainly come from the powertrain, exhaust system, etc. Therefore, reducing the vibration and noise caused by the exhaust system has become an important task to control the NVH in the vehicle. The suspension near the powertrain of the exhaust system feels the greatest vibration transmitted by the powertrain. The design of this suspension is particularly critical. Generally, the first suspension is installed on the subframe of the vehicle, and the strength...
