TECHNICAL FIELD

[0001] The utility model relates to the technical field of bearing support, in particular to a single capsule type bearing seat. BACKGROUND

[0002] In the automobile chassis system, the power transmission of front and rear wheels is realized through the power shaft. However, due to the long distance between the front and rear wheels, the length of the power shaft is also designed to be relatively long. Considering the problem of body shaking during driving, the middle part of the power shaft may be offset, which affects the stability of power transmission.

[0003] In order to solve the above problems, the prior art adds a bearing seat in the middle of the automobile chassis, the bearing seat is provided with a bearing for supporting the power shaft, and a rubber ring is arranged between the bearing seat and the bearing as a buffer layer. However, the conventional rubber ring is a solid structure, which not only has a large weight, but also has limited buffering effect, and needs to be improved. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the problem that the rubber ring between the bearing seat and the bearing in the prior art is a solid structure, which not only has a large weight, but also has limited buffering effect, and needs to be improved.

[0005] To solve the above problems, the utility model provides a single capsule type bearing seat, which comprises a bearing, a rubber ring and a support body provided with a support hole, one end surface of the rubber ring in the direction perpendicular to the axis is provided with a groove in the circumferential direction, so that the radial section of the rubber ring forms a C shape, the rubber ring is embedded on the inner circumferential side of the support hole, and the inner circumferential wall of the support hole is provided with a first limiting convex ring abutting to the rubber ring to realize axial limiting; the bearing is embedded on the inner circumferential side of the rubber ring, and the inner circumferential wall of the rubber ring is provided with a second limiting convex ring abutting to the bearing to realize axial limiting.

[0006] Compared with the prior art, the above scheme optimizes the structure of the rubber ring, forms a C shape in the radial section of the rubber ring through the groove, not only effectively reduces the weight of the rubber ring, but also the rubber ring with a C-shaped section has good deformation capacity and can provide better buffering effect; at the same time, the support hole realizes axial limiting of the rubber ring through the first limiting convex ring, and the rubber ring realizes axial limiting of the bearing through the second limiting convex ring, which ensures the connection stability between them.

[0007] In an improved scheme, the positions of the two groove walls corresponding to the groove of the rubber ring are respectively embedded with annular skeletons, so that the structure of the rubber ring is more reliable and has high strength.

[0008] In an improved scheme, the skeleton near the bearing side of the rubber ring has a bending part extending to the second limiting convex ring, so as to ensure the structural strength of the second limiting convex ring.

[0009] In an improved scheme, the material of the framework is metal, which has high strength and good durability.

[0010] In an improved scheme, the first limiting convex ring is located on the side of the supporting hole away from the notch of the groove, and the second limiting convex ring is located on the side of the rubber ring away from the notch of the groove. Since the rubber ring is generally deformed towards the side away from the notch of the groove when being extruded, the first limiting convex ring and the second limiting convex ring are both designed to be located on the side away from the notch of the groove, so that better axial limiting effect can be achieved.

[0011] In an improved scheme, the outer edge of the end face of the side of the rubber ring away from the notch of the groove is provided with a V-shaped groove in the circumferential direction, and the groove width and the groove depth of the V-shaped groove are both smaller than the groove width and the groove depth of the groove. The V-shaped groove can further reduce the weight of the rubber ring and improve the deformation capacity of the rubber ring.

[0012] In an improved scheme, the outer peripheral wall and the inner peripheral wall of the rubber ring are both provided with a wave pattern extending in the circumferential direction, so as to improve the frictional resistance between the rubber ring and the supporting hole and between the rubber ring and the bearing.

[0013] In an improved scheme, one side of the supporting body is provided with a mounting table, and the mounting table is provided with a mounting hole. The supporting body is assembled to the vehicle body through the mounting table. BRIEF DESCRIPTION OF DRAWINGS
