Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a bracket for fixing an intermediate bearing of a propeller shaft of an automobile.

[Prior Art] Conventionally, when attaching an intermediate bearing holder of an automobile propeller shaft to a bracket attached to the lower surface of a floor frame of an automobile with bolts, the bolts were tightened while holding the propeller shaft body with one's arms. For this reason, the work was difficult to perform, leading to worker fatigue.

The object of this invention is to provide a bracket that does not require an operator to hold the propeller shaft body and can be tightened with bolts while the intermediate shaft holder of the propeller shaft is placed on the bracket.

[Means for Solving the Problems] In order to achieve the above object, this invention provides an intermediate bearing fixing bracket which is attached to the lower surface of a floor frame of an automobile and is used to fix an intermediate bearing holder of a propeller shaft. A pair of temporary fixing pieces that can support the flanges formed on both sides of the intermediate bearing holder on the top surface, and a pair of temporary fixing pieces that can ultimately support both flanges of the intermediate bearing holder by being located on the top of each of these temporary fixing pieces. a pair of support pieces, the temporary fixing pieces are formed in an L-shape in plan view, and have relief portions in which nuts fixed in advance to the lower surfaces of both flanges of the intermediate bearing holder are located; An elongated hole is formed in the support piece through which a bolt, which is screwed into a nut fixed to the lower surface of both flanges of the intermediate bearing holder, can be inserted from the upper surface side of each support piece.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

First, Figure 1 shows the floor frame 1 of the automobile body.
2 shows the working state when assembling the intermediate bearing holder 2 of the propeller shaft. This holder 2
Nuts 3 are fixed by welding or the like to the lower surfaces of the flanges 2a formed on both sides of the flange 2a. However, in FIG. 1, only one side of the bearing holder 2 and a bracket 4, which will be described later, is shown.

A bracket 4 attached to the floor frame 1
As is clear from FIGS. 2 and 3, it is made by bending a single metal plate. In its unfolded state, as shown in FIG. 4, it consists of a plurality of segments 4a to 4g.
In addition, in this Figure 4, the dotted line indicates each segment 4.
The folding line between a and 4g is shown.

The segments 4c, 4d, 4e are folded lines 4h
Accordingly, the segments 4b and 4g are bent. Further, each of the segments 4c, 4d, and 4e is bent along folding lines 4i, 4j so as to have a U-shaped cross section, thereby forming a mounting portion 5 shown in FIGS. 1 to 3.

Note that the segments 4b and 4g shown in FIG.
g is a reinforcing portion between the mounting portion 5 and the segment 4b. Additionally, segments 4a and 4
b is bent along a bending line 4k.

The opening side 5a of the mounting portion 5 faces the holder 2 as shown in FIG. And the mounting part 5
is formed into a U-shaped cross section, the segment 4c is aligned with the support piece 5b, and the segment 4d is aligned with the vertical line 5.
In c, the segment 4e becomes the temporary fixing piece 5d, and the segment 4f becomes the claw part 5e. The temporary fixing piece 5d has a second
As is clear from FIGS. 4 to 4, the relief portion 5f is formed in the shape of a notch. With this, the temporary fixing piece 5
The planar shape of d is an L-shape having the aforementioned claw portion 5e. On the other hand, a bolt insertion hole 6 which is long in the longitudinal direction of the vehicle is formed in the support piece 5b.

In the above configuration, in order to attach the holder 2 shown in FIG.
Place it on top of it temporarily. During this temporary placement, the nut 3 on the lower surface of the flange 2a is located in the relief part 5f of the temporary fixing piece 5d formed in an L shape, and this nut 3 interferes with the edge of the relief part 5f and is attached to the mounting part 5. In contrast, the horizontal position of the nut 3 is determined. This determines the temporary placement position of the flange 2a relative to the temporary fixing piece 6, and in this state, the elongated bolt insertion hole 6 and the nut 3 are substantially aligned.

Next, a bolt (not shown) is inserted into the bolt insertion hole 6 from the direction of arrow Q shown in FIG. 3 and screwed into the nut 3. Then, the temporary fixing piece 5d
Flange 2a of holder 2 temporarily placed on top of
is raised until it touches the lower surface of the support piece 5b of the mounting portion 5 and is tightened. As a result, the holder 2 is properly assembled to the bracket. By temporarily placing the intermediate bearing holder 2, which has a considerable weight, the operator can move the holder 2 from this point on.
This eliminates the need to hold the bolts and allows you to focus solely on bolt tightening.

[Effects of the Invention] In the present invention, the flange of the intermediate bearing holder is temporarily placed on the temporary fixing piece of the bracket attached to the floor frame of the automobile, that is, the holder is positioned with respect to the bracket. Therefore, temporary placement and positioning only need to be performed once, and the assembly of the intermediate bearing holder is completed by simply tightening the bolts, improving work efficiency.
