Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine support device, and more particularly to an engine support device on an exhaust pipe side suitable for mounting an automobile engine to a vehicle body.

As shown in FIGS. 1 to 3, a conventional general engine support device uses a mounting rubber 5 to connect a rolling stopper 2 fixed to a vehicle body 1 and a bracket 4 fixed to an engine 3. A heat shielding plate for shielding the mounting rubber 5 from heat dissipation from the exhaust pipe 6 was welded to the bracket 4 of the engine support device on the exhaust pipe 6 side.

The rolling stopper 2 can come into contact with an upper rolling stopper 8 that projects from the bracket 4 in the direction of the rolling stopper 2, thereby restricting downward movement of the bracket 4 with respect to the vehicle body 1. . An extended portion 9 of the mounting rubber 5 is attached to the contact surface of the rolling stopper 8 with the rolling stopper 2, and this extended portion 9 provides a buffer against collision between the rolling stoppers 2 and 8. ing.

The extension part 9 further extends into the gap D between the upper rolling stopper 8 and the shield plate 7, and the heat shield plate 7 is in contact with this extension part 9. The heat shield plate 7 is made of a thin metal plate and has low rigidity. Therefore, unless the end portion 10 on the rolling stopper 2 side is supported by some means, abnormal vibration may occur. However, in order to enhance the heat shielding effect, it is desirable to provide a sufficient air layer, that is, a gap D, between the rolling stopper 8 and the heat shielding plate 7, and it is preferable to weld the heat shielding plate 7 to the upper rolling stopper 8. is not possible. Conventionally, therefore, the end portion 10 was brought into contact with the extension portion 9 with sufficient pressure to elastically support the end portion 10. However, since the heat shield plate 7 has low rigidity, it is difficult to sufficiently increase the elastic support force, and if the elastic support force is not increased too much, the heat shield plate 7 will deform and the elastic support force will eventually decrease. It became. Further, in order to optimize the elastic supporting force, it is necessary to improve the shape precision of the heat shield plate 7, but it is not easy to improve the precision of the heat shield plate 7 formed by pressing a thin metal plate.

This invention was devised to solve these conventional problems, and aims to provide an engine support device that can reliably support the end of a heat shield plate while ensuring a sufficient heat shielding effect. purpose.

The engine support device according to the present invention has a conventional configuration in which the end portion of the heat shield plate on the rolling stopper side is held between mounting rubbers.

Next, an embodiment of the engine support device according to the present invention will be described based on the drawings.

In FIGS. 4 to 6, the engine support device includes a rolling stopper 2 fixed to a vehicle body (not shown) with a bolt 11, a bracket 4 bolted to the engine, and this bracket 4.
The bracket 4 includes an upper rolling stopper 8 that contacts the rolling stopper 2 to restrict the downward movement of the engine, and a mounting rubber 5 that connects the engine to the rolling stopper 2. A lower rolling stopper 13 is provided which abuts against and restricts upward movement of the engine.

A heat shielding plate 7 is welded to the upper surface 14 of the bracket 4, and this heat shielding plate 7 extends above and along the sides of the mounting rubber 5 to connect the mounting rubber 5 to an exhaust pipe (not shown). ) is shielded from heat radiation. Mounting rubber 5 for heat shielding plate 7
The part 15 that shields the upper part of the upper rolling stopper 8 extends along the upper rolling stopper 8, and a sufficient gap D is provided between the upper rolling stopper 8 and the part 15 to form a sufficient air layer. has been done.

The mounting rubber 5 has an extension portion 9 that extends along the lower surface of the upper rolling stopper 8 and is then folded back to the upper surface of the rolling stopper 8.
A V-groove 17 is formed in an end 16 of the extension portion 9 on the upper surface side of the upper rolling stopper 8. End portion 10 of the heat shield plate 7 on the rolling stopper 2 side
is fitted into the V-groove 17, and the end portion 10 is inserted into the V-groove 17.
It is held by mounting rubber 5 at. As a result, the end portion 10 is supported sufficiently strongly, and abnormal vibration of the heat shield plate 7 is prevented.
When installing the heat shield plate 7, the end portion 10 is
Since the end portion 10 can be supported simply by fitting into the groove 17, attachment of the heat shield plate 7 is easy.

As mentioned above, the engine support device according to the present invention includes a rolling stopper fixed to the vehicle body,
A bracket fixed to the engine, a mounting rubber that connects the bracket and the rolling stopper, and a heat shield that is fixed to the bracket and covers the mounting rubber to insulate the mounting rubber from the heat of the exhaust pipe. In an engine support device equipped with a heat shield plate, the end of the heat shield plate on the rolling stopper side is held by the mounting rubber, so that the end of the heat shield plate is secured while ensuring sufficient heat shielding effect. It has the excellent effect of being able to reliably support the parts.
