Description

Technical Field

[0001] This utility model relates to the field of wheel hub unit technology, specifically a third-generation wheel hub unit with a directional sensor. Background Technology

[0002] A wheel hub is a cylindrical metal component mounted on an axle that supports the tire's inner contour; it's commonly referred to as a "wheel rim" or "steel rim." In the past, passenger car wheel hub bearings were mostly paired single-row tapered roller or ball bearings. With technological advancements, passenger cars now widely use passenger car wheel hub units.

[0003] For example, Chinese patent CN219505938U discloses a nutless, riveted round automotive wheel hub unit, which relates to the field of automotive wheel hub units. It includes: a top cover, a controller fixedly connected to the top of the top cover, a rotating ring provided below the top cover, a mounting base fixedly connected to the outer surface of the rotating ring, a flange provided below the rotating ring, a scanner fixedly connected to the bottom of the top cover, a positioning block provided to the left of the scanner, a cover plate provided below the top cover, and a riveted round provided at the top inside the top cover. This invention utilizes a push rod to align a locking block on the cover plate with a slot inside the rotating ring. The push rod is then pressed downwards, compressing the spring. Rotating the cover plate clockwise moves the locking block to its maximum position in the slot, moving the opening above the push rod. The spring's elasticity pushes the push rod into the opening, thus fixing the cover plate and preventing it from rotating and opening during vehicle operation. However, in traditional wheel hub units, the outer and inner rings move relative to each other during operation. Regular lubrication of the internal ball bearings requires opening the sealing rings at both ends to add lubricant, followed by reinstalling the sealing rings. This process is complex. Therefore, a third-generation wheel hub unit with a directional sensor is proposed to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a third-generation wheel hub unit with a directional sensor, which offers advantages such as convenient lubrication of the internal wheel hub structure and solves the problem of complex traditional lubrication operations.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned purpose of facilitating the lubrication of the internal hub structure, this utility model provides the following technical solution: a third-generation hub unit with a directional sensor, comprising:

[0008] The main body has an inner ring fitted on the outer surface of one end of the main body, an outer ring fitted on the outer surface of the inner ring, an oil pipe installed on the outer surface of the inner ring, and an oil outlet hole opened on the outer surface of one end of the inner ring.

[0009] The sensor is fixedly mounted on one end of the outer ring by bolts, and a magnetic ring is provided at the connection between one end of the sensor and the inner ring.

[0010] Preferably, the magnetic ring is made of nitrile rubber, which increases the sensor's sealing performance and prevents dust from entering.

[0011] Preferably, a plurality of balls are embedded between the outer ring and the inner ring, and a retainer is fitted on the outer surface of the plurality of balls to limit the rolling path of the roller and prevent the balls from deviating.

[0012] Preferably, a sealing ring is embedded at one end of the connection between the outer ring and the main body to increase the sealing performance of the outer ring installation.

[0013] Preferably, the oil passage is threaded to the outer ring, a piston is inserted into the top of the oil passage, and a baffle is fixedly installed at the bottom of the oil passage. When lubrication is required, the piston inside the oil passage is opened, and then the oil passage is rotated to push it inward.

[0014] Preferably, a connecting flange is integrally connected to the outer surface of the other end of the main body, and fixing bolts are installed on the outer surface of the connecting flange, through which the hub unit is installed.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a third-generation wheel hub unit with a directional sensor, which has the following advantages:

[0017] By installing an oil passage pipe on the surface of the outer ring, when lubrication is needed, the piston inside the oil passage pipe is opened, and then the oil passage pipe is rotated and pushed inward until the oil outlet at one end of the oil passage pipe enters the channel between the inner and outer rings. Then, lubricating oil is injected at the other end, allowing the lubricating oil to enter the channel through the oil passage pipe for lubrication. This avoids disassembling the sealing ring and is more convenient.

[0018] Directional sensors are typically magnetoelectric. When the wheel rotates, the magnet or sensing element inside the sensor interacts with the magnetic markers or toothed rings on the wheel, generating electrical signals. These signals are then converted into wheel speed and direction data and transmitted to the vehicle's electronic control unit. Attached Figure Description

[0024] Please see Figure 1-3 This utility model provides the following technical solution: a third-generation wheel hub unit with a directional sensor, comprising a main body 1, wherein a connecting flange 2 is integrally connected to the outer surface of the other end of the main body 1, and fixing bolts 3 are installed on the outer surface of the connecting flange 2, and the wheel hub unit is installed through the connecting flange 2.

[0025] In this example, an inner ring 4 is fitted on the outer surface of one end of the main body 1, and an outer ring 5 is fitted on the outer surface of the inner ring 4. An oil passage pipe 11 is installed on the outer surface of the inner ring 4, and an oil outlet hole 13 is opened on the outer surface of one end of the inner ring 4. The oil passage pipe 11 is threadedly connected to the outer ring 5. A piston 12 is inserted into the top end of the oil passage pipe 11, and a baffle is fixedly installed at the bottom end of the oil passage pipe 11. When lubrication is required, the piston 12 inside the oil passage pipe 11 is opened, and then the oil passage pipe 11 is rotated and pushed inward until part of the oil outlet hole 13 at one end of the oil passage pipe 11 enters the channel between the inner ring 4 and the outer ring 5. Then, lubricating oil is injected into one end, so that the lubricating oil enters the channel through the oil passage pipe 11 for lubrication.

[0026] In this example, the sensor 10 is fixedly installed at one end of the outer ring 5 by bolts. When in use, the sensor 10 transmits the speed and direction data of the wheel to the vehicle's electronic control unit. A magnetic ring 9 is provided at the connection between one end of the sensor 10 and the inner ring 4. The magnetic ring 9 is made of nitrile rubber, which increases the sealing of the sensor 10 and prevents dust from entering.

[0027] Among them, a plurality of balls 7 are embedded between the outer ring 5 and the inner ring 4, and a retainer 6 is fitted on the outer surface of the plurality of balls 7. The retainer 6 limits the rolling path of the roller and prevents the balls 7 from deviating. A sealing ring 8 is embedded at one end of the connection between the outer ring 5 and the main body 1. The sealing ring 8 increases the sealing performance of the outer ring 5.

[0028] The working principle of this embodiment is as follows:

[0029] The sensor 10 is mounted on one end of the outer ring 5 by bolts. When in use, the sensor 10 transmits the wheel speed and direction data to the vehicle's electronic control unit. A magnetic ring 9 is provided at the connection of the sensor 10 to increase the sealing of the sensor 10 and prevent dust from entering.

[0030] An oil passage pipe 11 is installed on the surface of the outer ring 5. When lubrication is required, the piston 12 inside the oil passage pipe 11 is opened, and then the oil passage pipe 11 is rotated and pushed inward until part of the oil outlet hole 13 at one end of the oil passage pipe 11 enters the channel between the inner ring 4 and the outer ring 5. Then, lubricating oil is injected into the other end so that the lubricating oil enters the channel through the oil passage pipe 11 for lubrication. After lubrication is completed, the oil passage pipe 11 is reset outward and the oil outlet hole 13 is closed to prevent dust from entering. Then, the piston 12 closes one end of the oil passage pipe 11.
