Abstract

(57) [Summary] [Purpose] The object of the present invention is to provide good heat shield and rigidity to the heat shield plate of the engine mount insulator. [Structure] An L-shaped reinforcing plate 18D is brought into contact with a lower side of a heat shield plate 18 attached to an engine mount insulator 6 via an air layer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat shield plate for a mount insulator of a front engine of an automobile or the like.

[0002]

[Prior Art]

 As shown in FIG. 3, in order to mount the front engine (1) in an automobile or the like, the mounting brackets (3, 3) are hung vertically from predetermined positions of the left and right side members (2, 2), and the mounting brackets (3 , Mount the engine mount member (4) between them, attach the base brackets (5, 5) to both ends of the engine mount member (4), and attach the engine mount insulator to the base brackets (5, 5). Install the engine mount bracket (7,7) via (6,6).

A cushioning material (6A, 6A) such as rubber is arranged on the insulator (6, 6), and the cushioning material (6A, 6A) is emitted from the exhaust pipe (1A) of the engine (1). As shown in FIGS. 4 and 5, a heat shield plate (8) is extended from the engine support surface (6B) of the insulator (6) in order to protect it from heat.

The conventional heat shield plate (8) is composed of a horizontal portion (8A) and an inclined portion (8B) inclined downward from the horizontal portion (8A), and a flange (8C) is provided on one side edge for reinforcement. And a bead (8D) is formed on the other side edge.

[0005]

[Problems to be solved by the device]

 However, since the conventional heat shield plate (8) has a single-layer structure, the heat shield property is not sufficient, and even if the flange (8C) and the bead (8D) are formed, a sufficient reinforcing effect cannot be obtained. However, the rigidity is insufficient, and the chattering noise easily occurs due to the vibration while the vehicle is running.

[0006]

[Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides a horizontal portion (18B) and an inclined portion that are extended from an engine support surface (6B) of an engine mount insulator (6). A heat shield plate (18) comprising a heat shield plate body (18A) composed of (18C) and an L-shaped reinforcing plate (18D) abutting on the lower side of the heat shield plate body (18A). To do.

[0007]

[Action]

 The body (18A) of the heat shield plate (18) consists of a horizontal part (18B) and an inclined part (18C), and an L-shaped reinforcing plate (18D) is abutted on the lower side of the body (18A). Therefore, a double structure is formed by the main body (18A) and the reinforcing plate (18D), and the air layer A exists between them. The air layer A exerts effective heat shielding properties. Further, the main body (18A) is reinforced by the reinforcing plate (18D), and the rigidity is greatly improved.

[0008]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. The mount insulator (6) of the front engine (1) includes a base plate (6B), a support plate (6C), and the base plate (6B). ) And a support plate (6C) and a cushioning material (6A) such as rubber sandwiched between the support plate (6C) and a mounting bolt (6D) protruding from the upper surface of the support plate (6C).

The body (18A) of the heat shield (18) is composed of a horizontal portion (18B) and an inclined portion (18C) inclined downward from the horizontal portion (18B). The L-shaped reinforcing plate (18D) is brought into contact with. The main body (18A) and the reinforcing plate (18D) have a double structure, and an air layer A is formed between them.

In this way, the rigidity of the main body (18A) is greatly improved by the reinforcing plate (18D), and the air layer A interposed between the main body (18A) and the reinforcing plate (18D) is excellent. Has a heat shield effect.

[0011]

[Effect of the device]

 Therefore, the heat shield of the present invention is excellent in heat shield effect and rigidity, and chatter noise is completely prevented.
