High-suitability sound absorbing and damping automobile exhaust pipe support

Abstract

The invention discloses a high-suitability sound absorbing and damping automobile exhaust pipe support and relates to the mechanical field. The high-suitability sound absorbing and damping automobile exhaust pipe support comprises a support body which is provided with two installing holes; the axes of the two installing holes are parallel with each other; each installing hole is internally provided with a connection sleeve; and rubber layers are arranged between the connection sleeves and the installing holes. Each connection sleeve comprises an outer pipe, an inner pipe, front covers and rear covers, wherein the diameter of the outer pipe is large, the diameter of the inner pipe is small, the front covers and the rear covers are welded to the two ends of the outer pipe and the two ends of the inner pipe in a blocking manner, the front covers and the rear covers are all in the shape of a ring and are connected between the outer pipe and the inner pipe, the front covers are provided with a plurality of threaded holes, and the positions, close to the front covers, of the inner pipe are provided with pressing devices. A sound absorbing casing pipe is further connected between each connection sleeve and the corresponding rubber layer in a sleeving manner. The automobile exhaust pipe support has a good damping and noise lowering effect, is high in suitability and can adapt to exhaust pipes of different sizes, connection is tight, the exhaust pipes are not prone to looseness, the overall structure is compact, the weight is small, the automobile oil consumption is indirectly reduced, and the energy-saving performance is good.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile exhaust pipe bracket with high adaptability for sound absorption and shock absorption. Background technique [0002] At present, the existing exhaust pipe bracket includes a bracket body and two connecting sleeves fixed on the bracket body. The connecting sleeve and the bracket body are generally hard-connected. The vibration of the exhaust pipe installed on it and the vibration of the frame are easily transmitted to each other, causing the exhaust pipe to vibrate greatly, which is easy to cause the exhaust pipe to break and fail. Moreover, the exhaust pipe bracket of this structure is generated during driving. There is also a lot of noise, resulting in noise pollution. For example, Chinese patent application No. 201220755118.1 discloses a new type of exhaust pipe bracket, which includes a rectangular vertical plate, and the lower edge of the vertical plate is folde...

AI Technical Summary

Problems solved by technology

The bracket designed with this structure does solve the problem of high vibration and noise of the exhaust pipe, but because the size of the connecting sleeve is fixed, its adaptability is poor. For a small-sized exhaust pipe, it needs to be replaced Only the connecting sleeve or the entire bracket is required, which increases the cost to a certain extent and wastes resources, and the connecting sleeve of this type of bracket is a solid pipe body, which still has defects in shock absorption and noise reduction, and needs to be improved
