Embodiment 1

[0020] Such as figure 2 As shown, the skeleton 10 of the integrated magnetic sealing device is a "匚"-shaped structure, the first side 11 of the skeleton 10 is provided with a magnetic rubber strip 20, the second side 12 of the skeleton 10 is provided with a rubber seal 30, and the second side 13 In order to fix the side, that is, the magnetic rubber strip 20 and the rubber seal 30 are arranged on the frame 10, and the magnetic rubber strip 20 and the rubber seal 30 are set on the "匚" shaped frame 10 at the same time, so as to realize the integrated installation of the magnetic part and the seal , to avoid accumulative errors when two frames are used together, and reduce the cost of one frame.

Embodiment 2

[0022] Such as image 3 As shown, the skeleton 10 of the integrated magnetic sealing device is a "匚"-shaped structure, the first side 11 of the skeleton 10 is provided with a magnetic rubber strip 20, the second side 12 of the skeleton 10 is provided with a rubber seal 30, and the second side 13 In order to fix the side, a magnetic rubber strip 20 and a rubber seal 30 are installed on the "匚"-shaped frame 10 at the same time, so as to realize the integrated installation of the magnetic part and the seal, avoid the cumulative error when two frames are used together, and reduce a frame , reducing costs. The first side 11 and the second side 12 of the "匚"-shaped structural skeleton 10 are chamfered and connected to reduce the occupied volume of the "匚"-shaped skeleton 10, and when the skeleton 10 is manually pressed into the bearing, the chamfered joint serves as a force bearing It is convenient for fingers to exert force on the skeleton 10, and it is convenient for the skeleton...

Embodiment 3

[0024] Such as image 3 As shown, the skeleton 10 of the integrated magnetic sealing device is a "匚"-shaped structure, the first side 11 of the skeleton 10 is provided with a magnetic rubber strip 20, the second side 12 of the skeleton 10 is provided with a rubber seal 30, and the second side 13 In order to fix the side, a magnetic rubber strip 20 and a rubber seal 30 are installed on the "匚"-shaped frame 10 at the same time, so as to realize the integrated installation of the magnetic part and the seal, avoid the cumulative error when two frames are used together, and reduce a frame , reducing costs.

[0025] The first side 11 and the second side 12 of the "匚"-shaped structural framework 10 are chamfered and connected. The first side 11 and the second side 12 of the "匚"-shaped structural skeleton 10 are chamfered and connected to reduce the occupied volume of the "匚"-shaped skeleton 10, and when the skeleton 10 is manually pressed into the bearing, the chamfered joint serves...

Abstract

The invention discloses an integrated magnetic sealing device and an integrated magnetic sealing ring. The integrated magnetic sealing device comprises a framework, the framework is of a left-square-bracket-shaped structure, a first side face of the framework is provided with a magnetic rubber strip, and a second side face of the framework is provided with a rubber sealing piece. The left-square-bracket-shaped framework is provided with the magnetic rubber strip and the rubber sealing piece at the same time, integrated mounting of the magnetic piece and the sealing piece is achieved, the accumulative error generated when two frameworks are matched is avoided, one framework is omitted, and the cost is lowered.

Description

technical field [0001] The invention relates to a magnetic sealing device, in particular to an integrated magnetic sealing device for a hub bearing unit and an integrated magnetic sealing ring comprising the integrated magnetic sealing device. Background technique [0002] In the automotive ABS system, the wheel speed is detected through the cooperation of the ABS sensor and the magnetic part in the hub bearing unit, and the hub bearing unit is also sealed by the seal. Such as figure 1 As shown, two skeletons are arranged in the existing wheel hub bearing unit to support the magnetic part and the sealing part respectively, and then the two skeletons are combined together and then pressed into the bearing unit. During the press-in process, the combination of the two skeletons combined is likely to cause the cumulative error of the press-in, resulting in a decrease in fit accuracy. Contents of the invention [0003] The purpose of the present invention is to provide an int...
