When a pump mounted on an automobile, for example, a pump for circulating cooling water for cooling an engine, an inverter, a motor, or the like, is mounted on a vehicle body via a bracket, the vibration of the pump is reduced by the vibration of the vehicle body. It is demanded to reduce transmission to the pump and not to generate unpleasant noise due to vibration between the pump and the bracket.

However, when the pump 101 and the bracket 102 are directly mounted with screws without interposing a buffer member as in the prior art, the vibration of the electric motor and the pump section is transmitted to the vehicle body without attenuating. Can not meet the demands.

Accordingly, the present invention reduces the vibration and uncomfortable sound by interposing a buffer member between the pump and the bracket, and makes the buffer member and the pump body effective by minimizing the strength of the bracket. It is an object of the present invention to provide a pump mounting device and a pump mounting bracket to be held by the pump.

[0006]

On the bracket side, a pair of fitting portions are formed facing each other in a direction orthogonal to the insertion direction of the cushioning member, forming fitting grooves respectively opening the inside and both ends in the insertion direction. On one side of the direction orthogonal to the facing direction, a reinforcing rib formed by bending the main part of the bracket is formed along the facing direction of the two fitting portions, and is formed in a direction perpendicular to the facing direction of the two fitting portions. On the other side, a retaining piece formed by cutting and raising the main part of the bracket is arranged, and the cushioning member is fitted to the two fitting portions and a cushioning member is provided between the retaining piece and the reinforcing rib. A pump mounting device characterized by holding a pump body.

According to the present invention, since the buffer member is interposed between the pump body and the bracket, transmission of vibration and noise generated from the pump to the bracket is attenuated.

The cushioning member and the pump body are sandwiched between the reinforcing rib and the retaining piece, with the reinforcing rib formed on the bracket serving as a stopper.

Since the reinforcing rib is formed by bending the main portion of the bracket without cutting, the cut-and-raised hole is not formed unlike the case where the stopper is formed by cutting and raising. Therefore, the rigidity of the bracket is not reduced.

Further, when the buffer member and the pump body are sandwiched by the retaining piece, since the rigid reinforcing rib is sandwiched as a reference surface, the mounting position of the buffer member and the pump body becomes accurate.

Further, the reinforcing ribs and both fitting portions of the bracket can be easily bent by press working or the like.

According to a second aspect of the present invention, a pair of fitting portions are formed in the main portion of the bracket in a direction perpendicular to the inserting direction of the pump body, and the pair of fitting portions are respectively opened inside and both ends in the inserting direction.

In the drawing, reference numeral 27 denotes a hole cut and raised in the fitting portion 19, and reference numeral 28 denotes a hole cut and raised in both the retaining pieces 20 and 21.

Next, an assembling method in this embodiment will be described.

First, with both side portions 8b and 8c of the cushioning member 8 opened outward from the state shown in FIG. 4, they are positioned on both sides of both mounting plates 6 and 7 of the pump body 5, and The two side plates 8b, 8c are pressed toward the two mounting plates 6, 7 to fit the two mounting plates 6, 7 into the two fitting grooves 9, 10, and the buffer member 8 is assembled to the pump body 5. As a result, both side portions 8b and 8c of the cushioning member 8 cover the mounting plates 6 and 7, and the front side 8
The inner surface 8f of a contacts the front surface of the pump body 5.

Next, both side portions 8b, 8 of the cushioning member 8 will be described.
c is inserted into the fitting grooves 18c, 19c of the fitting portions 18, 19 from the front side of the bracket 15 together with the pump body 5, and the rear end contact portions 1b on both side portions 8b, 8c thereof.
As shown in FIG. 6, the fittings 3 and 14 are inserted until they contact the inner surface 17 a of the reinforcing rib 17 of the bracket 15. At the time of insertion, the tip ends 20 of the both retaining pieces 20 and 21 are not inserted.
Since c and 21c do not protrude above the upper surface of the main body 15a of the bracket 15, the insertion can be performed without any trouble.

When inserted as described above, the retaining projection 1 protruding from the lower surface of the front side 8a of the cushioning member 8 is formed.
2 corresponds to the main body 15a of the bracket 15, but since the entire cushioning member 8 is formed of an elastic material together with the front side 8a and the retaining projection 12, the front side 8a is formed by the thin corners 8d and 8e. The escape protrusions 12 are bent forward as they escape upward, so that the insertion is easily performed.

When the stopper 12 is inserted to a predetermined position, the tip of the knob 12c of the retaining projection 12 fits into the large-diameter tip 24b of the insertion hole 24. And this knob part 12c
Is pinched by hand on the back side of the bracket 15 and pulled toward the locking hole 23 while being pulled downward. As a result, the locking groove 12a of the retaining protrusion 12 is fitted to the periphery of the locking hole 23, and the buffer member 8 is prevented from falling off. Further, by pulling the retaining projection 12 to the position of the locking hole 23 in this manner, the front side portion 8a is restored and stands at a predetermined position.

Next, the base portions 20 of the both retaining pieces 20 and 21 will be described.
A and 21a are bent upward and plastically deformed substantially horizontally as shown by a chain line in FIG. 8, and their locking portions 20b and 21b are raised to protrude from the front surface of the front side 8a of the cushioning member 8. Press on the part 11. Thereby, the contact portions 13, 1 formed at the rear ends of both side portions 8b, 8c of the cushioning member 8 are formed.
4 is slightly deformed and pressed against the inner surface 17a of the reinforcing rib 17, and the projection 11 formed on the front surface of the front side 8a is slightly deformed and pressed against the locking portions 20b and 21b. The buffer member 8 is assembled together with the pump main body 5 in a predetermined position by the reinforcement ribs 20 and 21 and the reinforcing rib 17.

In this assembled state, the bracket 15
Is attached to the vehicle body with a screw through the screw hole 26.

As described above, since the reinforcing ribs 17 are formed at the rear portion of the bracket 15, the strength of the bracket 15 is increased, and the reinforcing ribs 17 serve as the cushioning member 8.
And also functions as a stopper for holding the pump body 5 via. Therefore, a cut-and-raised hole is not formed in the rear portion of the bracket 15 unlike the case where the bracket is cut and raised to form a stopper. The rigidity of the bracket 15 can be increased as compared with the case where the bracket 15 is used.

Furthermore, when the retaining pieces 20 and 21 are raised and clamped, the reinforcing rib 17 having high rigidity serves as a positioning reference, so that the cushioning member 8 and the pump body 5 are accurately arranged at predetermined positions. Also, no excessive deformation is applied to the cushioning member 8.

Further, the reinforcing rib 17 and the two fitting portions 18,
19 can be easily bent by press working or the like.

Further, one fitting portion 18 is connected to the bracket 1
Since the side of the main part 15a in FIG. 5 is extended and formed by bending it, no cut-and-raised hole for forming the fitting part 18 is formed in the main part 15a. Therefore, the rigidity of the bracket 15 can be increased as compared with the case where the cut-and-raised hole is formed, and the rigidity of the bracket 15 can be further increased in combination with the structure of the reinforcing rib 17.

After the buffer member 8 and the pump main body 5 are assembled to the bracket 15 as described above and attached to the vehicle body, vibration and noise of the pump 1 generated when the pump 1 is driven are applied to the bracket 15. Transmission is buffer member 8
Is attenuated.

[0048]

As described above, according to the first aspect of the present invention, transmission of vibration and noise generated from the pump to the bracket can be attenuated by the buffer member.

Further, since the reinforcing rib formed on the bracket also serves as one stopper, there is no need to provide another stopper separately.

Further, since the reinforcing rib is used as a stopper, a cut-and-raised hole for forming the stopper is not formed, so that the rigidity of the bracket does not decrease.

Further, since the cushioning member and the pump main body are assembled with the high rigidity reinforcing rib as a reference plane, they can be assembled at accurate positions.

Further, the reinforcing ribs and both fitting portions can be easily bent from the main portion of the bracket by pressing or the like.

According to the second aspect of the present invention, it is possible to provide a bracket exhibiting the effect of the bracket.

According to the third aspect of the present invention, one of the fitting portions can be formed without reducing the rigidity of the bracket.
The rigidity of the bracket can be further prevented from lowering in combination with the reinforcing rib.
