Problems solved by technology

[0004] (1) If the volume of other parts is too large and the layout space of the engine compartment is small, it is difficult to find a fixed point on the engine block for the muffler. It can only be fixed on the chassis of the car, but it will affect the installation of other parts
[0005] (2) The supporting seat for fixing the transmission shaft of the car and the bracket for fixing the muffler are two independent parts connected to the engine block, which has a high inherent vibration frequency and low strength, so that the NVH performance is not high
[0006] (3) The assembly process is more complicated and the cost is higher

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 The fixed bracket shared by the automobile drive shaft and the muffler shown is an integral structure formed by aluminum alloy die-casting, which has a first connecting plate 1 fixed to the engine block by bolts, and a cylindrical bracket for supporting the drive shaft 5 of the automobile. The supporting sleeve 2 and the second connecting plate 3 fixed by bolt connection with the muffler 6, the first connecting plate 1 is parallel to the axis of the cylindrical supporting sleeve 2, and the first connecting plate 1 is connected to the cylindrical supporting sleeve through the reinforcing rib 7 perpendicular to it. The outer wall of 2 is connected, the second connecting plate 3 is an L-shaped structure, and its vertical part is perpendicular to the axis of the cylindrical supporting sleeve 2, and the top of the vertical part of the second connecting pl...

Abstract

The invention discloses a fixing support shared by an automobile transmission shaft and a silencer. The fixing support is of an integrated structure and comprises a first connecting plate, a cylindrical supporting sleeve and a second connecting plate, wherein the first connecting plate is connected with an engine cylinder body, the cylindrical supporting sleeve is used for supporting the automobile transmission shaft, and the second connecting plate is connected with the silencer. The first connecting plate and the second connecting plate are connected to the outer wall of the cylindrical supporting sleeve. According to the fixing support, the arrangement space for an engine room can be saved, fixing strength between the automobile transmission shaft and the silencer can be improved, and the assembly technology can be simplified.

Description

technical field [0001] The invention relates to a fixing bracket of an automobile part, in particular to a fixing bracket shared by an automobile transmission shaft and a muffler. Background technique [0002] With the development of engine technology, the engine is becoming more and more miniaturized, and its structure is becoming more and more compact. In the limited engine room space, it is becoming more and more difficult to complete the arrangement and fixing of parts. For the automobile transmission shaft and the muffler, the traditional fixing method is: the automobile transmission shaft is fixed on the engine block through the bearing seat, and the muffler is fixed on the engine block or the automobile chassis through the bracket. [0003] This fixed form has the following problems: [0004] (1) If the volume of other parts is too large and the layout space of the engine compartment is small, it is difficult to find a fixed point on the engine block for the muff...
