Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub bearings, in particular to a mirror image wheel hub bearing. Background Art

[0002] The wheel hub bearings of automobiles are usually set on the left and right sides. To test the wheel speed, sensors need to be installed on the corresponding wheel hub bearings. The two sensor positions are set in mirror image on the left and right sides. Therefore, the corresponding sensor mounting holes on the two wheel hub bearings are also set in mirror image, that is, the left wheel hub bearing can only be placed on the left side, and the right wheel hub bearing can only be placed on the right side. They cannot be used interchangeably. When assembling in the main engine factory of the automobile, the staff may easily take the wrong wheel hub bearing, which may cause rework due to wrong installation. At the same time, the wheel hub bearing manufacturers need to distinguish, sort, and store the workpieces during the processing, which increases the production cost. Utility Model Content

[0003] The utility model aims to provide a mirror-image wheel hub bearing, which satisfies the left-right versatility of the wheel hub bearing by arranging a pair of mirror-image sensor mounting holes on the wheel hub bearing, thereby avoiding the problem of incorrect installation of the wheel hub bearing by the host manufacturer in the later stage, and at the same time simplifies the processing technology and reduces the production cost.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A mirror-image wheel hub bearing comprises an outer ring, a steel ball, an inner ring and a sealing assembly, wherein the outer ring is formed with a short ferrule and a long ferrule arranged coaxially;

[0006] A pair of symmetrically arranged sensor mounting holes are formed on the side wall of the short ferrule.

[0007] Through the above technical solution, the two sensor mounting holes are symmetrically arranged. Regardless of whether the left wheel hub bearing or the right wheel hub bearing is assembled, a sensor can be installed on a corresponding sensor mounting hole, and the installation position does not change, which can improve the versatility of the wheel hub bearing.

[0008] The utility model is further configured as follows: the sensor installation hole is waist-shaped and faces the central axis of the short ferrule; the contour of the sensor installation hole is consistent with the contour of the outer wall of the installed sensor; the sensor is inserted into the sensor installation hole.

[0009] The utility model is further configured as follows: a flange is formed in the middle of the outer ring, and a bolt press-fitting hole is formed on the flange;

[0010] The two sensor mounting holes are symmetrically arranged about the center line of the bolt press-fitting hole and the short ferrule, so that the sensor mounting position is more accurate.

[0011] The utility model is further configured as follows: two grooves are formed on the inner wall of the outer ring, two grooves are correspondingly provided in the inner ring and the sealing assembly, and a plurality of steel balls are provided between each inner ring and the corresponding groove;

[0012] One sealing assembly is clamped between one inner ring end and the short ferrule, and another sealing assembly is clamped between the other inner ring end and the long ferrule; the sealing assembly is located outside the corresponding plurality of steel balls. The sealing assembly can keep the steel balls and the channel clean, thereby improving the stability of the bearing.

[0013] The utility model is further configured as follows: the sensor installation hole is located on the outside of the corresponding sealing component, thereby ensuring that the sensor and the sealing component are staggered and ensuring the normal operation of the sensor.

[0014] The outstanding effects of the utility model are:

[0015] Compared with the prior art, by arranging a pair of mirror-image sensor mounting holes on the wheel hub bearing, the left and right versatility of the wheel hub bearing is met, which can avoid the problem of incorrect installation of the wheel hub bearing by the host manufacturer in the later stage, and at the same time simplifies the processing technology and reduces production costs.
