たり、エンジンアブソーバ装着が困難になる等の
不都合があつた。 Conventionally, vibrations have been transmitted from the engine mount support to the front suspension member, which has sometimes caused noise inside the vehicle interior. Conventionally, the shape of the front mount bracket on the engine side was changed to reduce vibration transmission to the front suspension member. There were inconveniences such as it becoming complicated and making it difficult to install the engine absorber.

供することを目的とする。 This idea was made to solve the above-mentioned conventional disadvantages, and it increases the rigidity of the front suspension member mount support without making it difficult to install the engine or absorber, and transmits information from the front suspension member to the body. An object of the present invention is to provide an engine mount support structure for a front suspension member that is capable of reducing vibration caused by vibrations.

である。 This idea divides each engine front mount bracket attached to the upper left and right surfaces of the front suspension member in the width direction of the vehicle body into two at approximately the center in the width direction, and extends in the front and rear direction of the vehicle body and extends approximately toward the upper surface of the front suspension member. The above object is achieved by sandwiching and welding a vertical bulkhead between the two divided engine front mount brackets and integrally welding it to the upper surface of the front suspension member.

ものである。 Embodiments of the present invention will be described below with reference to the drawings. As shown in the figure, each engine front mount bracket 2 attached to the left and right upper surfaces of the front suspension member 1 in the vehicle width direction is divided into two approximately at the center in the width direction, and the engine front mount brackets 2 are divided into two at substantially the center in the width direction. Bulkhead 3 approximately perpendicular to the upper surface 1A of the front suspension member
is sandwiched and welded between the two divided engine front mount brackets 2, and integrally welded to the front suspension member upper surface 1A.

It is sandwiched and welded together.

ことになる。 In this way, the rigidity of the engine mount support portion in the longitudinal direction is greatly increased, so vibrations transmitted from the engine (not shown) to the body through the front suspension member 1 are significantly reduced. Therefore, the noise inside the vehicle is reduced.

できた。 According to experiments conducted by the present inventors, as shown in Figure 3, when the vertical axis represents the sound pressure level of vehicle interior noise and the horizontal axis represents the secondary frequency due to engine rotation, the relationship between the two is as follows. In the case of the present invention, as shown by the solid line in the figure, and in the case of the present invention as shown by the chain line in the figure, it was confirmed that the noise inside the vehicle was significantly reduced.
