Abstract

(57) [Summary] [Object] The purpose of the present invention is to prevent the vibration of the muffler from being directly transmitted to the vehicle body and to improve the heat shield effect of the heat shield plate. [Structure] Both the muffler (13) and the heat shield (16) are attached to the attachment member (17) which is passed over to the side members (11, 11). [Effect] The vibration of the muffler (13) is dispersed and relaxed by the mounting member (17), and the heat shield effect can be improved by bringing the muffler (13) and the heat shield plate (16) close to each other.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an engine exhaust system muffler of a vehicle such as an automobile.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, a mounting bracket (2, 2) is extended from a pair of left and right side members (1, 1) of a vehicle body frame, and is extended from the both ends of the muffler (3) to the attachment bracket (2, 2). The exhaust system mounting brackets (4, 4) are attached via bolts and nuts (5, 5). The heat shield (6) of the muffler (3) was attached directly to the side members (1,1). Note that F is the floor of the vehicle body.

[0003]

[Problems to be solved by the device]

 In the above conventional configuration, the muffler (3) is directly attached to the side members (1, 1) so that the vibration of the muffler (3) is directly transmitted to the vehicle body. It is necessary to form the cutouts (6A) in the heat plate (6). If the cutouts are not formed on both sides of the heat shield plate (6), install the muffler (3) in the center line as shown in FIG. There are problems such as a large offset from CL, a large distance between the muffler (3) and the heat shield (6), and a low heat shield effect.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention passes a mounting member (17) to a pair of left and right side members (11, 11) of a vehicle body frame, and attaches an exhaust system muffler () to the mounting member (17). An exhaust system muffler mounting structure, in which 13) and a heat shield plate 16 are mounted on the upper side thereof, is provided.

[0005]

[Action]

 In the present invention, since the muffler (13) is attached to the side members (11, 11) via the attachment member (17), the vibration of the muffler (13) is dispersed and reduced by the attachment member (17). To be done. The muffler (13) and the heat shield (16) can be mounted together on the mounting member (17), and the heat shield (16) can be brought close to the muffler (13).

[0006]

【Example】

 1 and 2, a pair of left and right side members (11, 11) of a vehicle body frame is disposed below a floor F of a vehicle body, and the side members are installed at the muffler mounting position. The mounting member (17) is attached to the lower surface of the member (11,11) by a bolt-nut (19,19) via a vibration-proof rubber (18,18). The mounting member (17) is provided with a pair of left and right mounting brackets (12, 12), and the exhaust system mounting brackets (14, 14) of the muffler (13) are provided on the side surfaces of the mounting bracket (12, 12). ) Is attached by the bolt-nuts (15, 15), and the heat shield plate (16) is attached to the lower surface by the bolt-nuts (21, 21) via the anti-vibration rubber (20, 20).

According to the present invention, as in the present embodiment, it is possible to perform double vibration isolation by using the anti-vibration rubber (18, 20), and the heat shield plate (16) and the muffler (13) are brought close to each other to improve the heat shield efficiency. Can be improved. Further, the vibration of the muffler (13) is dispersed and moderated by the mounting member (17) and the anti-vibration rubber (18).

[0008]

[Effect of the device]

 Therefore, in the present invention, the vibration of the muffler is prevented from being directly transmitted to the vehicle body, and the heat shield effect of the heat shield plate can be improved.
