Abstract

PURPOSE: To provide a mount installation structure for suspending an engine main body in a reduced installation space. CONSTITUTION: An opening part 12 is formed on the side face of a rectangular frame 8, and on the circumferential face of the rectangular frame 8 in the vicinity of the opening part 12, a bead 13 is formed or a flat plate is fixed, while in the inside of the opening part 12, a mount 5 to which an arm 7, a rod and the like are connected is journalled. As the rectangular frame 8 is reinforced by means of the bead 13 or the flat plate, the mount 5 can be journalled to the inside of the frame 8 so as to suspend an engine main body and the like. On the other hand, an installation space can be efficiently used, as a conventional bracket for mount installation is dispensed with. In the rectangular frame 8 in which the bead 13 is formed, the number of parts and assembling man-hours can be reduced, so that lighting in weight can be accomplished.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount mounting structure for fixing an engine mount of an automobile or a mount of a connecting portion of a trading rod to a vehicle body frame.

[0002]

2. Description of the Related Art Conventionally, when an engine is suspended on a vehicle body frame, engine mounts are provided at several places to support the weight of the engine and absorb vibrations and the like during engine operation. Engine mount 1 shown in FIG.
Is a mount 5 in which a shaft (bolt) 3 arranged at the center of the cylindrical member 2 is supported by a mount rubber 4 and a bracket 6 which supports the shaft 3, and an arm provided on the engine body on the outer periphery of the cylindrical member 2. 7 is fixed. Also, FIG.
As also shown in FIG. 3, the bracket 6 is welded to the side surface of the vehicle body frame 8 so that the load of the engine can be increased.
It is adapted to be hung on the vehicle body frame 8 via. The shaft portion of the mount 5 is a combination of the bolt 3 and the cylindrical inner diameter member 9, the bolt 3 is inserted into the bracket 6, and the nut 10 is inserted.
I am fixing it with.

Further, as shown in FIG. 8, when a trailing rod 11 for suspending a wheel is pivotally supported on a vehicle body frame 8 provided on both sides (one side is shown) of the vehicle body, it is pivotally supported on a bracket 6. The mount 5 is provided at the end of the rod 11, and the bracket 6 is welded to the body frame 8.

The above two mount structures are individually installed. However, when the installation positions are almost the same, a structure in which two mounts are pivotally supported by one bracket by changing the bracket shape has been proposed. There is. As an example, Japanese Utility Model Publication No. 1-10257 discloses a structure in which two differential mount members and a suspension mount member are attached to a bracket consisting of a first member and a second member, and the number of parts of the mount bracket is reduced. There is.

[0005]

However, in order to install the mount 5, a bracket 6 for supporting the shaft must be attached to the vehicle body frame 8, and the space around the bracket 6 causes a restriction on peripheral members. . Also,
When the mounting side surface of the bracket 6 of the vehicle body frame 8 faces downward, the welding work becomes complicated, and it is inefficient to provide the welding process as a separate process in the preceding stage of the line.

It is an object of the present invention to provide a mount mounting structure which does not use a bracket which requires an installation space.

[0007]

In order to achieve the above object, the present invention forms an opening on the side surface of a rectangular frame and forms a bead on the outer peripheral surface of the rectangular frame near the opening, or a flat plate. And a mount to which an arm, a rod and the like are connected is pivotally supported inside the opening.

[0008]

The present invention is configured as described above, and since the frame is reinforced with the beads or the flat plate, when the mount is axially supported inside the frame and a load is applied to the frame through the mount, the bead or the flat plate is attached. Force is applied to maintain the frame shape.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the mount 5 for suspending the engine has an outer cylinder member 2 connected to an arm 7 attached to an engine body (not shown), and is mounted on a side surface of a rectangular body frame 8. It is inserted in the formed opening 12. Here, the opening 12 is directed below the vehicle body,
A plurality of thickly beaded beads 13 are provided at the corners of the upper surface 8a and the vertical surface 8b of the vehicle body frame 8. Also,
A bolt hole 8c, which serves as a bearing for the mount 5, is formed in the vertical surface of the vehicle body frame 8 (see FIG. 3).

The mount 5 includes an outer cylinder member 2 and a cylindrical inner diameter member 9.
A mount rubber 4 is mounted between and, and a bolt (shaft) 3 is inserted into the cylindrical inner diameter member 9. Further, as shown in FIG. 2, the mount 5 inserted inside the body frame 8 is
A collar 14 is provided on both sides of the shaft to position and secure an operating space, and the shaft is supported by bolts 3 and nuts 10.

In this way, the body frame 8 is made rigid by the bead 13, and the mount 5 is directly attached to the body frame 8.
By pivotally supporting the engine, the load against the weight of the engine is strong and the engine can be suspended. Further, since the body frame 8 is provided with the function of the bracket 5, the conventional bracket 6 for pivotally supporting the mount 5 can be eliminated, the space of the mounting location can be reduced, the number of parts can be reduced, and the weight can be reduced. it can.

In the vehicle body frame 8 shown in FIGS. 4 and 5, a U-shaped reinforcing plate (flat plate) 15 is fixed adjacent to the opening 12 to ensure the rigidity around the mount mounting portion. Therefore, in FIG. 5, the mount 5 is attached to the end of the trailing rod 11, and the mount 5 is pivotally supported in the body frame 8 so that the wheels can be suspended.

[0013]

Since the present invention is constructed as described above, the mount necessary for suspending the engine and the wheels can be attached to the body frame reinforced with the bead or the flat plate. By eliminating the bracket for mounting the mount, the conventional installation space can be effectively used. Further, in the body frame having the beads, the number of parts and the number of assembling steps can be reduced, and the weight can be reduced.
