Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Because in the existing support frame structure, the damping rubber is arranged on the outer side of the bearing, and the bearing protrudes out of the surface, namely one end of the bearing is exposed to the air, the outer ring of the bearing is also exposed to the air, so that vulcanization cannot be directly carried out in the production process, an outer sleeve is required to be additionally arranged on the damping rubber outer ring, the damping rubber outer ring is assembled on the support frame, and then subsequent operation is carried out.

To solve this problem, referring to fig. 1 to 3, an aluminum bracket intermediate support includes: fixing frame 10 and supporting frame 20

Specifically, the supporting framework 20 comprises a rectangular support 11 and an annular support 12 integrally formed inside the rectangular support 11, the supporting framework 20 is arranged inside the annular support 12, a plurality of protruding buckling parts 201 are arranged on the outer side of the supporting framework 20, the buckling parts 201 are buckled on two side surfaces of the annular support 12 so as to fix the supporting framework 20, a bearing sleeve 21 is arranged in the middle of the supporting framework 20, a bearing body 23 is detachably fixed inside the bearing sleeve 21, damping rubber 22 is filled between the bearing body 23 and the bearing sleeve 21, and a bearing fixing part 24 is arranged at the joint of the bearing body 23 and the outer end face of the damping rubber 22.

Unlike the prior art, the bearing body 23 is limited by the bearing housing 21 while the supporting frame 20 is supported, so that the bearing body 23, the bearing housing 21 and the supporting frame 20 are separated to form an annular cavity with one side open, and the damping rubber 22 is arranged in the annular cavity, so that only one side open is provided, and when the bearing body 23 is fixed by the bearing fixing part 24, the end surface of the damping rubber 22 can be covered at the same time, thereby the damping rubber 22 is completely sealed, and when the vulcanization operation is performed, the damping rubber 22 is not affected by the vulcanization operation, and the vulcanization operation can be directly performed.

The annular bracket 12 is clamped from two sides through the buckling parts 201, so that stable position limitation is formed, namely the supporting framework 20 is tightly fixed on the annular bracket 12, and the fixing frame 10 and the supporting framework 20 are aluminum profile brackets.

In an embodiment, referring to fig. 1 and 2, the supporting framework 20 is in an annular structure, a buckling part 201 is integrally formed on one side of the supporting framework 20, a supporting plate 202 is integrally formed on the other side of the supporting framework 20, the supporting plate 202 protrudes out of the supporting framework 20 and is buckled with a surface of the annular bracket 12 on one side far away from the buckling part 201, the bearing sleeve 21 is arranged at a middle position of the supporting plate 202, and a through groove with the same inner diameter as that of the center of the bearing body 23 is arranged at the middle position of the supporting plate 202.

That is, the support plate 202 needs to provide a support surface for supporting the bearing housing 21 and ensuring that the transmission shaft connected to the central position of the bearing body 23 can penetrate, in addition to being fastened to the ring bracket 12 at the outer side.

In one embodiment, referring to fig. 1, both ends of one side of the rectangular bracket 11 are provided with a connecting portion 111, and a surface of the connecting portion 111 and one side of the rectangular bracket 11 away from the connecting portion 111 are provided with connecting holes.

The vehicle body is mounted through the connecting hole, and a positioning workpiece such as a through bolt or a pin is usually fixed in the connecting hole.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
