BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of assembling an automobile, and more particularly to a method of assembling an automobile that can improve the efficiency of assembling a change device for operating a transmission.

0002

BACKGROUND OF THE INVENTION In recent years, methods for assembling automobiles have been developed, for example, in Japanese Unexamined Utility Model Publication No. 108183/1983 or Japanese Unexamined Patent Publication No. 63/1983
As described in Publication No. 265779, in order to improve the workability of outfitting work, the floor members and the upper body other than the floor members are assembled in their respective assembly processes, and their outfitting is almost completed, and then A method of assembling an automobile in which, in the main assembly process, a floor member is assembled to an upper body to assemble the vehicle body, and then suspension parts such as the engine, transmission, exhaust pipe, heat insulator, and suspension are assembled to the vehicle body. is proposed. In the above automobile assembly method, in the vehicle assembly process, the floor member is equipped with a change device for transmission operation as well as a floor mat and a seat device. In this case, the change lever of the change device is attached to the tunnel part of the floor member. The change rod of the change device is temporarily assembled to the lower inner surface of the tunnel portion.

0003

[Problems to be Solved by the Invention] In the above-mentioned method of assembling a car, the change lever and change rod are not connected to each other during transport of the floor member from the outfitting line or when assembling the floor member to the upper body in the main assembly process. If the temporary assembly comes off, the change device may fall off from the floor member, or only the change rod temporary assembly may come off, leaving the change rod in an unrestrained state. There is a problem in that the efficiency of the assembly work and the work of connecting the change rod and the transmission is significantly reduced. Furthermore, since the heat insulator is assembled to the tunnel portion after the floor member is assembled to the upper body, there is also a problem in that work efficiency in assembling the heat insulator is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for assembling an automobile that can reliably prevent a change device from falling off a floor member and improve the efficiency of assembling the change device.

[0005]

[Means for Solving the Problems] The method for assembling an automobile according to the present invention is to replace a floor member having a tunnel portion with almost complete outfitting with an upper body other than the floor member with almost complete outfitting of interior parts. In the method of assembling an automobile to an upper body, in the sub-assembly step of assembling the floor member, a change lever for transmission operation is fixedly assembled to an opening at the upper end of a tunnel portion of the floor member, and the change lever is A change rod connected at one end to the proximal end is disposed inside the lower part of the tunnel part, and then a heat insulator extending along the tunnel part is attached to the lower inner surface of the tunnel part, and the change rod is connected to the base end part at one end. It supports the rod.

[0006]

[Operation] In the automobile assembly method according to the present invention, in the sub-assembly process for assembling the floor member, the change lever is fixedly assembled to the opening at the upper end of the tunnel part of the floor member, and the change rod is inserted under the tunnel part. Next, a heat insulator is attached to the lower inner surface of the tunnel portion, and the change rod is supported by the heat insulator. In the sub-assembly process for assembling floor members, the change lever is fixedly assembled to the tunnel part, the heat insulator is also assembled to the tunnel part, and the change rod is supported by the heat insulator, so when transporting the floor member, When assembling the floor components to the upper body,
It is possible to reliably prevent the change device from falling off the floor member and the change rod from becoming unrestrained. Therefore, it is possible to improve the work efficiency of the work of assembling the heat insulator and the exhaust pipe to the tunnel portion of the floor member and the work of connecting the change rod to the transmission. Furthermore, since the heat insulator is assembled to the floor member without assembling the floor member to the upper body, the efficiency of the work of assembling the heat insulator can also be improved.

[0007]

Effects of the Invention According to the method for assembling an automobile according to the present invention, in the subassembly process for assembling the floor member, the change lever is fixedly assembled to the tunnel portion, and the heat insulator is is assembled into the tunnel part and the change rod is supported by a heat insulator, so it is possible to reliably prevent the change device from falling off the floor member or the change rod from becoming unrestrained. Effects such as being able to improve work efficiency in assembling insulators and exhaust pipes, and connecting change rods to transmissions, and improving work efficiency in assembling heat insulators can also be obtained.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, the present invention is applied to a method of assembling a four-door sedan front-wheel drive automobile.

As shown in FIG. 1, the body of the automobile is
Floor member FB and upper body U other than floor member FB
The upper body UB is assembled in the main assembly process, and in parallel with this, the floor member FB is assembled in the sub-assembly process, and then the upper body UB and the floor member are assembled in the respective outfitting lines of the vehicle assembly process. The FB is separately outfitted, and then the upper body UB and the floor member FB are transferred to a joining station, where the floor member FB is assembled to the upper body UB.

To explain the subassembly process for assembling the floor member FB, a second cross member 11, a front floor panel 10 having a tunnel portion 10a,
A floor member FB is assembled by joining the third cross member 12, center floor 13, and left and right front frames 14. Next, in this subassembly process, the floor member FB is fitted with equipment such as floor mats, rear seat belts, and rear consoles. is assembled, and then the change device 2
0 is assembled into the tunnel portion 10a.

To explain how to assemble the change device 20 to the tunnel portion 10a, as shown in FIGS. 2 and 3,
First, the change lever 21 is inserted from below the tunnel portion 10a into the opening 10c formed at the upper end of the tunnel portion 10a, and then the base plate 22 at the base end of the change lever 21 is connected to the bolt 1. Tunnel part 10 with nut 2
Fasten it to the upper end of a. In this state, the change rods 23 and 24 connected at the rear end to the base end of the change lever 21 are disposed in an unrestricted manner inside the lower side of the tunnel portion 10a. Next, the heat insulator 33 externally mounted on the catalytic converter 31 installed in the exhaust pipe 30 is inserted into the tunnel part 10 from below the tunnel part 10a.
a, and the left and right side ends of the heat insulator 33 are fixed and assembled to the left and right side inner surfaces of the tunnel portion 10a with bolts 3. By assembling the heat insulator 33 to the tunnel portion 10a in this way, the change rods 23 and 24 are supported by the heat insulator 33 in a state facing forward. Next, Figure 4・
As shown in FIG. 5, the front seat 4 is attached to the floor member FB.
1 is assembled, the rear seat 42 is temporarily placed, and then the floor member FB, which has been almost completely outfitted in this way, is assembled.
is transferred to the pallet P and positioned, and then the floor member FB is transferred together with the pallet P to the conveyance line L and conveyed to the joining station CS.

On the other hand, the upper body UB that has been assembled in the main assembly process is transferred to the upper body outfitting line of the vehicle assembly process, where the upper body UB is fitted with an instrument panel, seat belt, assist handle, sun visor, etc. The upper body UB, which has been outfitted with various interior parts and whose outfitting has been substantially completed, is transported by the hanger 4 to the joining station CS. At the joining station CS, the floor member FB is assembled to the upper body UB to assemble the vehicle body, and then at the suspension parts assembly station,
Suspension parts such as the engine, transmission, exhaust pipe, and suspension are assembled to the vehicle body.

As described above, in the subassembly process for assembling the floor member FB, the change device 20 is fixedly assembled to the tunnel portion 10a, the heat insulator 33 is assembled to the tunnel portion 10a, and the change rod 23 of the change device 20 is fixedly assembled to the tunnel portion 10a. 24 is supported by the heat insulator 33, so that the changing device 20 does not fall off from the floor member FB when the floor member FB is transported from the subassembly process to the joining station CS or when the floor member FB is assembled to the upper body UB. , it is possible to reliably prevent the change rods 23 and 24 from becoming unrestrained. Furthermore, the work of finally assembling the change lever 21 to the tunnel portion 10a after assembling the floor member FB to the upper body UB can be omitted.
In addition, the change rods 23 and 24 and the transmission can be easily connected at the suspension parts assembly station, so
The efficiency of assembling the change device 20 can be improved. In addition, the floor member FB is attached to the upper body U.
Since the heat insulator 33 is finally assembled to the floor member FB before the heat insulator 33 is assembled to the floor member B, the work efficiency for assembling the heat insulator 33 can also be improved. It goes without saying that the above method for assembling a car can be applied not only to front-wheel drive type cars but also to rear-wheel drive type cars.
