Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bearing support device comprising two brackets that engage with the outer periphery of the bearing so as to sandwich the bracket to support the bearing on the vehicle body.
In particular, the present invention relates to the support device characterized by a temporary fixing mechanism for both brackets.

[Conventional example]

As a conventional bearing support device, there is, for example, the one shown in FIG. 1, which is known from Japanese Utility Model Application Publication No. 58-90831. That is, 1 is the vehicle body, 2 is the propeller shaft, 3 is the center bearing,
4 and 5 are brackets, respectively. Bracket 4,
Reference numeral 5 denotes a center bearing mounting bracket for supporting the center bearing 3 mounted on the propeller shaft 2 on the vehicle body 1. The center part of each of brackets 4 and 5 is
It has a shape corresponding to the outer periphery of the center bearing 3, and each end forms a joint part 4a, 5a, 4b, 5b where both the brackets 4, 5 are joined to each other. Reference numeral 6 denotes a bolt/nut for temporarily fixing the brackets 4 and 5 together when they are mounted on the center bearing 3, and serves as a temporary fixing mechanism for the brackets 4 and 5. Numerals 7 and 8 are bolt nuts for fixing the brackets 4 and 5 to the vehicle body 1.

Therefore, these assembly steps are as follows after mounting the center bearing 3 on the propeller shaft 2.
Attach brackets 4 and 5 to center bearing 3. In this installation, after the brackets 4 and 5 are arranged around the outer periphery of the center bearing 3, both brackets 4 and 5 are fixed with bolts and nuts 6. In this state, the center bearing 3 is supported on the vehicle body 1 by fixing the brackets 4 and 5 to the vehicle body 1 with bolts and nuts 7 and 8.

However, such a conventional bearing support device uses a pair of bolts and nuts 6 as a temporary fixing mechanism for the brackets 4, 5, which temporarily fixes the brackets 4, 5 to the center bearing 3. In this case, a plane part is required for the bolt/nut 6, and as a result, there is a problem in that the joint parts 4a, 5a are forced to be larger and heavier. Further, the temporary fixing of the brackets 4 and 5 required a tool to tighten the bolts and nuts 6, resulting in a problem of poor efficiency.

[Purpose of invention]

The present invention has been developed focusing on such conventional objectives, and aims to reduce the size and weight of the bracket by making the joints between the brackets as small as possible, and also to reduce the temporary fixing work of the brackets. The aim is to improve the efficiency of

[Structure of the idea]

The present invention is a two-piece system that engages with the outer periphery of a bearing mounted on the shaft to support the bearing on the vehicle body.
The two brackets are opposed to each other, and the bearing is sandwiched between the center portions of the two brackets from the outside, and the two brackets are temporarily fixed to each other when assembled to the bearing. In a bearing support device equipped with a temporary fixing mechanism, a joint formed at one end of both brackets includes a pawl formed on one bracket and a pawl formed on the other bracket at a position corresponding to the pawl. , a pawl engaging portion with which the pawl engages, a through hole penetrating through both brackets provided at the other end of both brackets, and a clip inserted into both through holes to engage both brackets. The present invention relates to a bearing support device comprising the temporary fixing mechanism.

〔Example〕

The present invention will be explained below based on illustrated embodiments. 2 to 4 are diagrams showing embodiments of the present invention.

First, the structure will be explained. Numerals 4 and 5 are upper and lower brackets, and both brackets 4 and 5 constitute a center bearing mounting bracket. The central portions of the brackets 4 and 5 have a shape corresponding to the outer periphery of the center bearing 3 mounted on the propeller shaft 2, and joint portions 4a, 5a, 4 are provided at the respective ends of the brackets 4 and 5.
b, 5b are formed. One joint 4a of one bracket 4 is integrally formed with a claw 10 projecting in the shape of a hook toward one joint 5a of the other bracket 5. The claw 10 is formed by punching out the joint portion 4a and then bending it.

Further, in one joint portion 5a of the other bracket 5, a hole 11, in which the pawl 10 is engaged, is opened at a position corresponding to the pawl 10 as a pawl engaging portion.

Furthermore, through holes 12 and 13 are individually formed in the joint parts 4a and 5b of the brackets 4 and 5 on the opposite side from the above, respectively, through which the brackets pass through when the two are joined.
The through holes 12 and 13 open in the same direction as the propeller shaft 2 at the sides of the brackets 4 and 5. Reference numeral 14 denotes a clip that is inserted into and engaged with the through holes 12 and 13, and has a head 14a and a shaft 1.
4b and a tip enlarged diameter part 14c, and the tip enlarged diameter part 14c passes through the through holes 12 and 13 to the bracket 4,
5, each part 14a, 14b,
14c engages the joint parts 4a and 5a.

Further, through holes 4c, 5c, 4d, and 5d for fixing the brackets 4 and 5 to the vehicle body 1 are provided in the joints 4a and 5a and the joints 4b and 5b. 1
5 is a bolt 16 for fixing the brackets 4, 5 to the vehicle body 1 by passing through the through holes 4c, 5c;
The brackets 4,
5 to the vehicle body 1.

Note that 17 is a universal joint of the propeller shaft 2.

Next, the action will be explained.

A center bearing 3 is mounted on the propeller shaft 2, and brackets 4 and 5 are attached to the center bearing 3. At this time, first, the joint parts 4a and 5a sides of the brackets 4 and 5 are brought close together,
The claw 10 is engaged with the hole 11 serving as the claw engaging part to join the joint parts 4a and 5a, and then the joint parts 4b and 5b are joined.
The through-holes 12 and 13 are aligned, and the wide-diameter end portion 1 of the clip 14 is inserted into the through-holes 12 and 13.
4c to maintain the bonded state of the bonded portions 4b and 5b. In this state, the brackets 4 and 5 are temporarily fixed to the center bearing 3.

In this state, bolts 15 and 16 are individually inserted into the through holes 4c and 5c and the through holes 4d and 5d of the brackets 4 and 5, thereby fixing the brackets 4 and 5 to the vehicle body 1. In this way, the center bearing 3 mounted on the propeller shaft 2 is fully tightened and supported by the vehicle body 1 via the brackets 4 and 5.

In this embodiment, the brackets 4 and 5 are used to support the center bearing 3 of the propeller shaft 2, but other shafts may be used instead of the propeller shaft 2, or other bearings may be used instead of the center bearing 3. Of course, it is also possible to use Further, in this embodiment, channel steel was used as the brackets 4 and 5, but
Other cross-sectional shapes such as angle iron may also be used. In addition, as the clip 14, the through hole 1
Other shapes and structures can be used as long as they can engage with the joints 2 and 13 and maintain the joined state of the joints 4b and 5b.

[Effect of idea]

As explained above, in the present invention, at the joint formed at one end of two brackets, there is a pawl formed on one bracket and a pawl formed on the other bracket at a position corresponding to the pawl. , a pawl engaging portion with which the pawl engages, a through hole penetrating through both brackets provided at the other end of both brackets, and a clip inserted into both through holes to engage both brackets. A temporary fixing mechanism was constructed. Therefore, temporary fixing of both brackets can be done by simply engaging the claw with the claw engaging part and engaging the clip with the communicating through hole. Improves sex. Further, according to the present invention, since bolts and nuts are not used to temporarily fasten both brackets, there is no need to provide a flat part for the bolts and nuts at the joint. Therefore, since the joint portion of the bracket can be made smaller, the bracket can be made smaller and lighter, and the degree of freedom in the shape of the vehicle body at the portion where the shaft is arranged is increased.
