[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle body mount device, and more particularly to a mount device that elastically supports between a chassis frame and a body in a vehicle with a chassis frame.

[0002]

[Prior Art]

 Generally, in an automobile with a chassis frame, in order to block vibration and noise from the suspension system and drive system transmitted through the frame, a body mount device made of rubber or the like is provided between the chassis frame and the body. It is provided. For example, as shown in FIG. 4, the body 8 is mounted on an outrigger or a bracket provided on the chassis frame 9 via an elastic body made of rubber or the like. By providing a plurality of such elastic mount devices, it is intended to prevent vibration and noise from the drive system and suspension system from being transmitted to the body 8. By the way, these conventional body mount devices are constructed as shown in FIG. That is, the elastic bodies 20 and 30 such as rubber are attached to the outriggers or brackets of the chassis frame 90 from above and below, the distance pipe 40 is inserted into the inside thereof for positioning, and the body 80 is placed above these elastic mount devices. It is mounted and fixed with bolts 50 and nuts 70. As shown in FIG. 4, a plurality of body mount devices adopting such an elastic mount method are provided between the body and the chassis frame, and the body is mounted on the chassis frame.

[0003]

[Problems to be solved by the device]

 However, in the body mounting method using this body mounting method, first, as shown in FIG. 5, the upper mount rubber 20 and the lower mount rubber 30 are temporarily fixed to the chassis frame 90, and then the upper mount rubber 20 is mounted. From the upper side, lower the body 80 to which the mounting bolt 50 is already mounted, and put the mounting bolt 50 into the distance pipe 40 that is pre-mounted in the upper mount rubber 20 and the lower mount rubber 30. It is intended to be inserted and mounted with the body 80. However, at this time, since the body mount device is provided at a plurality of places of the body as shown in FIG. 4, the position of the tip of the mounting bolt is not always the same as the position of the inner diameter of the distance pipe. I'm not always doing it. In some cases, the position of the inner diameter hole of the distance pipe 40 and the position of the tip end portion of the mounting bolt 50 may be displaced as shown by the alternate long and short dash line in FIG. In such a case, the upper surface of the upper mount gum 20 may push the mounting bolt 50 upward, causing the mounting bolt 50 to drop from the body 80 as shown by the arrow in FIG. 5 (mounting bolt 50). 50 will fall out from the mounting part of the body 80).

In order to prevent this from happening, in the conventional one, when mounting the body, the operator manually adjusts the mounting bolt 50 so that the mounting bolt 50 is fitted in the inner diameter hole of the distance pipe 40. I'm doing it. Moreover, as shown in FIG. 4, this body mount device is provided in a plurality of places for one vehicle, and therefore, when mounting the body, a plurality of workers must engage in the adjustment work. It is not preferable in terms of work efficiency. It is an object (problem) of the present invention to provide a body mount device capable of solving such a problem in mounting the body and improving work efficiency.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, a body is mounted on a chassis frame via an elastic body such as rubber, and the body, the chassis frame and the elastic body are tightened by mounting bolts, thereby In a body mount device for an automobile that elastically supports a body on the chassis frame, an upper surface of the elastic body has a mounting hole for inserting the mounting bolt at the center thereof, and the mounting hole is disposed in the center direction of the mounting hole. A plate having a mortar-shaped recess that inclines toward the front, and a spacer having a shape of a truncated cone for fitting into the mortar-shaped recess and having an elastic claw portion in the inner diameter portion After mounting the mounting bolts on the body using the spacers, The door is mounted so as to penetrate the inside of the elastic body, then, by tightening the bolt with a nut and the body and to a configuration which is adapted to elastically support on said chassis frame.

[0006]

[Action]

 By adopting the above configuration, in the present invention, when mounting the body, first, the mounting bolt 5 is inserted into the mounting hole 81 of the body 8 as shown by the chain line in FIG. When the mounting bolt 5 is inserted into the inner diameter portion of the spacer 1 by adding, the mounting bolt 5 is mounted (temporarily fixed) on the body 8 by elastically deforming the claw portion 11. When the body 8 is lowered onto the chassis frame 9 in such a state, the tip 52 of the mounting bolt 5 comes into contact with the slope of the recess 22 of the plate 21 attached to the upper surface of the elastic body.

As a result, an upward force Q is generated in the mounting bolt 5, but in this case, the thread of the threaded portion 51 of the mounting bolt 5 and the claw 11 of the spacer 1 are Because of the elastic force, the mounting bolts 5 are held in the body 8 without moving further upward because they are engaged with each other. Therefore, the tip portion 52 of the mounting bolt 5 moves downward along the inclined surface of the recess 22 of the plate 21 and is automatically inserted into the mounting hole 23. Further, the conical outer shape of the spacer 1 is guided into the recess 22 of the plate 21, and finally the mounting bolt 5 is provided with a through hole (in the distance pipe 4) provided inside the elastic body. ), And the mounted state is as shown in FIG. As described above, in the present invention, it is possible to omit the conventional work which requires the operator to manually install the mounting bolt 5 when mounting the body. As a result, when mounting the body 8 on the chassis frame 9, the mounting work of the mounting bolt 5 can be automatically performed.

Since the body mount device thus mounted is, as shown in FIG. 1, connected between the chassis frame 9 and the body 8 via an elastic body such as rubber. Vibrations and noises transmitted from the drive system or the suspension system to the chassis frame 9 are also blocked at the elastic body and are not transmitted to the body 8. Therefore, these vibrations and noises are not transmitted to the vehicle interior, and a quiet vehicle interior environment can be obtained.

The mounting bolt 5 is provided so as to penetrate through the inner diameter portions of the upper mount rubber 2 and the lower mount rubber 3, and the mounting bolt 5 is connected to the body 8 through the distance pipe 4 as shown in FIG. The body mount device is formed by mounting the lower mount rubber 3 so as to penetrate it and then tightening it with washers 6 and nuts 7. As shown in FIG. 4, the body mount device configured as described above is provided at a plurality of positions between the body 8 and the chassis frame 9.

Next, a procedure for assembling the body mount device having the above structure will be described. First, as shown in FIG. 1, the upper mount rubber 2, the lower mount rubber 3, and the distance pipe 4 are attached (temporarily attached) to the outrigger portion or the bracket portion of the chassis frame 9. On the other hand, the mounting bolt 5 as shown in FIG. 3 is attached (temporarily fixed) to the mount portion of the body 8 by using the spacer 1. At this time, since the spacer 1 is provided with the elastic claw portion 11, if the mounting bolt 5 is inserted in the direction of P in FIG. The claw portion 11 engages with the threaded portion 51 of the mounting bolt 5 to prevent the mounting bolt 5 from falling off the body 8.

As described above, the mounting bolt 5 and the body 8 to which the spacer 1 is attached are also mounted on the chassis frame 9 to which the mount rubbers 2 and 3 are attached. At that time, the mounting bolt 5 is attached. Even if the position of and the position of the mounting hole 23 for inserting the mounting bolt 5 of the plate 21 provided on the upper mount gum 2 are deviated, as shown in FIG. 3, the tip portion 52 of the mounting bolt 5 is It slides on the inclined surface of the mortar-shaped recess 22 of the plate 21 and is automatically guided into the mounting hole 23.
