Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.
See fig. 1-4;
an upper support structure of a rear shock absorber of the present embodiment includes:
a bracket housing 1, wherein the inside of the bracket housing 1 is hollow and formed into a mounting cavity;
the outer framework 2 is positioned in the mounting cavity of the bracket shell 1 and is attached to the inner wall of the bracket shell 1; and
an inner skeleton structure;
the inner skeleton structure is embedded into the outer skeleton 2;
an upper end cover 5 is fixed at the upper end of the bracket shell 1;
the upper supporting structure is connected with a piston rod of the vehicle shock absorber in a matched manner through an inner framework structure, and an upper end cover 5 of the upper supporting structure is connected with the shock absorber through a bolt;
the bracket shell 1 is connected with a metal plate of a vehicle body of the vehicle through bolts.
Specifically, this embodiment discloses a novel upper support structure suitable for rear shock absorber, and it includes support shell 1, the outer skeleton 2 of embedding in the support shell 1 and the inner skeleton structure of embedding in the outer skeleton 2 to fixed upper end cover 5 in support shell 1 upper end.
Wherein, the endoskeleton structure of this embodiment includes:
an inner frame 4 disposed inside the outer frame 2 along the axial direction of the bracket housing 1; and
a rubber sleeve 3 coated on the outer side of the inner framework 4;
the inner framework 4 is in interference connection with the outer framework 2 through the rubber sleeve 3.
The present embodiment further defines the composition of an inner frame structure including an inner frame 4 and a rubber sleeve 3 fitted over the outer portion of the inner frame 4. The inner frame 4 and the rubber sleeve 3 of this embodiment are vulcanized, and after being combined, are pressed into the outer frame 2, and finally, the outer frame 2 embedded with the inner frame structure is pressed into the bracket shell 1, and the upper end cover 5 is fixed by spin riveting.
Preferably, in terms of materials and processing technologies, the material of the bracket shell 1 in this embodiment is AlSil0MnMg cast aluminum material, and the bracket shell 1 is formed by adopting a low-pressure casting technology.
For assembly with a vehicle body sheet metal, both sides of the bracket housing 1 of the present embodiment have mounting portions 101 protruding toward the outside, and the mounting portions 101 have mounting holes 102 thereon; the bracket shell 1 is fixed at the mounting hole 102 through the bolt and the sheet metal assembly of the vehicle body. The mounting holes 102 on the bracket shell 1 of the upper supporting structure are connected with the metal plate of the vehicle body through bolts.
According to the stress condition, the mounting portion 101 and the bracket housing 1 of the embodiment not only design the reinforcing rib 103, but also can properly adjust the inclination angle of the reinforcing rib 103 according to the stress direction and the stress condition, specifically: the mounting portion 101 is arranged obliquely with respect to the horizontal plane; one end of the two mounting portions 101 connected to the bracket housing 1 and a portion of the bracket housing 1 located between the two mounting portions 101 are connected by a reinforcing rib 103.
