Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a positioning bolt structure of an automobile ABS wheel hub unit. Background Art

[0002] The automobile ABS system (anti-lock braking system) is one of the most important safety devices in modern automobiles. It prevents the wheels from locking during emergency braking by controlling the working state of the brakes, thereby maintaining the stability and controllability of the vehicle. As one of the key components of the ABS system, the hub unit locating bolt plays the role of fixing the wheel hub and transmitting the braking torque. Traditional locating bolts usually adopt a simple mechanical structure. Although it can meet basic connection requirements, they are prone to loosening, wear and other problems during long-term use. In addition, due to the lack of effective lubrication and maintenance methods, these problems are often difficult to detect and solve in a timely manner. Therefore, it is particularly important to develop a new type of automobile ABS hub unit locating bolt structure.

[0003] A Chinese patent discloses a positioning bolt (publication number: CN 204572697 U) comprising a head and a screw, with a positioning hole provided at the center of the end face of the head. The positioning hole comprises a conical outer hole and a cylindrical inner hole, the inner hole and the outer hole being connected, the diameter of the inner hole being larger than the minimum diameter of the cone, and the inner hole being gradually smaller from the top to the bottom of the outer hole. However, this positioning bolt structure is simple and, while it can meet basic connection requirements, is prone to loosening and wear during long-term use. In addition, due to the lack of effective lubrication and maintenance methods, these problems are often difficult to detect and resolve in a timely manner, thus requiring a positioning bolt structure for an automotive ABS wheel hub unit. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, that is, the positioning bolt structure is simple. Although it can meet the basic connection requirements, it is prone to loosening and wear during long-term use. In addition, due to the lack of effective lubrication and maintenance methods, these problems are often difficult to detect and solve in a timely manner. The proposed automobile ABS wheel hub unit positioning bolt structure is

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: the automobile ABS wheel hub unit positioning bolt structure described in the present invention includes a bolt body, which is characterized in that: a slot is provided on the edge of the outer wall of the bolt body, the number of the slots is 4 and they are arranged in an array with equal spacing, the inner wall of the bolt body is provided with an internal thread, the top of the inner wall of the bolt body is provided with a self-lubricating component, and one side of the top surface of the bolt body is provided with a micro-integrated sensor. This design can ensure a tight connection between the bolt and the wheel hub, improving the safety and stability of vehicle driving. At the same time, the self-lubricating component can reduce friction and wear and extend the service life. The micro-integrated sensor provides a convenient means of maintenance and monitoring, which helps to promptly identify potential problems and take measures to solve them.

[0006] Preferably, the self-lubricating component includes an annular lubrication groove containing micro-lubricant capsules. These capsules enable automatic lubrication replenishment, reducing the need for manual intervention. This not only improves efficiency but also reduces the risk of failure due to human error. The micro-lubricant capsules are heat-sensitive materials. When the ambient temperature reaches a certain threshold, they automatically rupture and release the lubricant within, thus achieving self-lubrication. This design not only improves lubrication efficiency but also reduces maintenance requirements, extending the life of the equipment.

[0007] Preferably, the surface of the bolt body is provided with an anti-corrosion coating, which can effectively prevent moisture, oxygen and other corrosive substances from corroding the bolt body, thereby extending its service life and maintaining good working condition.

[0008] Preferably, a cooling channel is provided within the bolt body, with an air inlet at the top and an air outlet at the bottom, both of which are connected to the cooling channel. The cooling channel helps dissipate heat, maintaining the bolt's stable performance in high-temperature environments. This is particularly important for vehicles operating for long periods of time or under high loads, as it prevents performance degradation or even damage caused by overheating.

[0009] Preferably, the cooling channel has a spiral structure. A spiral cooling channel can more effectively guide air flow, increase the heat dissipation area, and thus improve heat dissipation efficiency. This design allows the bolt to maintain good working condition under high temperature conditions.

[0010] Preferably, the bolt body is made of high-strength alloy steel. High-strength alloy steel has high strength and toughness, and can withstand large loads while resisting shock and vibration. This ensures that the bolt maintains stability and reliability even in harsh working environments.

[0011] The utility model is beneficial in that:

[0012] By providing a slot and internal thread structure, this application provides a tighter and more reliable connection between the bolt and the wheel hub or other components. This design helps reduce loosening caused by vibration or impact, thereby improving vehicle driving safety and stability. Self-lubricating components (such as micro-lubricant capsules) can automatically replenish lubricant, reducing friction and wear. This not only extends the service life of the bolt but also reduces maintenance costs. The surface is coated with an anti-corrosion coating, which effectively prevents the bolt body from being corroded by moisture, oxygen, and other corrosive substances. This helps maintain the bolt in good working condition and extends its service life. The internal cooling channel and spiral structure increase the heat dissipation area and improve heat dissipation efficiency. This is particularly important for vehicles that operate for long periods of time or under high loads, as it prevents performance degradation or even damage caused by overheating. The bolt body is made of high-strength alloy steel, which has high strength and toughness. This allows the bolt to withstand heavy loads while resisting impact and vibration, ensuring its stability and reliability in harsh working environments. Micro-integrated sensors can monitor parameters such as temperature and pressure in real time, providing timely data support for maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example

[0021] See also Figure 1-3 As shown, the automobile ABS wheel hub unit positioning bolt structure includes a bolt body 3, which is characterized in that: a slot 4 is provided on the outer wall edge of the bolt body 3, the number of the slots 4 is 4 and they are arranged in an array with equal spacing, an internal thread 1 is provided on the inner wall of the bolt body 3, a self-lubricating component is provided on the top of the inner wall of the bolt body 3, and a micro-integrated sensor 7 is provided on one side of the top surface of the bolt body 3. The micro-integrated sensor 7 is a common product on the market and can be purchased directly. This design can ensure a tight connection between the bolt and the wheel hub, and improve the safety and stability of vehicle driving. At the same time, the self-lubricating component can reduce friction and wear and extend the service life. The micro-integrated sensor 7 provides a convenient maintenance and monitoring means, which helps to detect potential problems in time and take measures to solve them.

[0022] In this embodiment, the self-lubricating assembly includes an annular lubrication groove 5, which is equipped with micro-lubricant capsules 6. These micro-lubricant capsules 6 enable automatic lubrication replenishment, reducing the need for manual intervention. This not only improves work efficiency but also reduces the risk of failure due to human error. The micro-lubricant capsules 6 are made of a heat-sensitive material. When the ambient temperature reaches a certain threshold, they automatically rupture and release the lubricant within, thus achieving self-lubrication. This design not only improves lubrication efficiency but also reduces maintenance requirements, extending the service life of the equipment.

[0023] In this embodiment, the surface of the bolt body 3 is provided with an anti-corrosion coating 2. The anti-corrosion coating 2 is a common product on the market and can be purchased directly. The anti-corrosion coating 2 can effectively prevent the corrosion of the bolt body 3 by moisture, oxygen, and other corrosive substances, thereby extending its service life and maintaining good working condition.

[0024] In this embodiment, a cooling channel 9 is provided within the bolt body 3. An air inlet 8 is provided at the top of the bolt body 3, and an air outlet 10 is provided at the bottom of the bolt body 3. Both the air inlet 8 and the air outlet 10 are connected to the cooling channel 9. The cooling channel 9 helps dissipate heat, maintaining the stability of the bolt in high-temperature environments. This is particularly important for vehicles operating for long periods of time or under high load, as it prevents performance degradation or even damage caused by overheating.

[0025] In this embodiment, the cooling channel 9 is a spiral structure. The spiral structure of the cooling channel 9 can more effectively guide the air flow, increase the heat dissipation area, and thus improve the heat dissipation efficiency. This design allows the bolt to maintain good working condition under high temperature conditions.

[0026] In this embodiment, the bolt body 3 is made of high-strength alloy steel. High-strength alloy steel has high strength and toughness, and can withstand large loads while resisting shock and vibration. This ensures that the bolt maintains stability and reliability even in harsh working environments.

[0027] The working principle of this embodiment is as follows: When connecting a wheel hub or other component to an axle, the bolt body 3 is first screwed into the corresponding threaded hole. At this point, the slots 4 on the outer wall engage with corresponding structures on the wheel hub, forming a secure connection. Simultaneously, the internal threads 1 on the inner wall tightly engage with other threaded components, further enhancing the stability of the connection. During use, as the bolt rotates and rubs, the micro-lubricant capsules 6 in the self-lubricating assembly are squeezed and ruptured, releasing lubricant that slowly seeps into the surface of the internal threads 1. The micro-lubricant capsules 6 are heat-sensitive materials. When the ambient temperature reaches a certain threshold, they automatically rupture and release the lubricant within, thus achieving self-lubrication. The surface of the bolt body 3 is covered with an anti-corrosion coating 2, which protects the metal surface from environmental factors such as air and moisture. When the vehicle is in operation, the frequent operation of the brakes generates a large amount of heat. This heat is transferred through the bolt body 3 to the interior of the cooling channel 9. The spiral design of the cooling channel 9 allows air to form vortices within it, accelerating the heat exchange process. Finally, the hot air is exhausted through the bottom air outlet 10, achieving rapid cooling. A micro-integrated sensor 7 collects real-time ambient temperature and pressure data. This data is transmitted via a wireless transmission module to the onboard computer or a remote server for analysis and processing. If an abnormality (such as excessive temperature) is detected, the system issues an alarm to alert the driver to inspect and repair the vehicle. This helps identify potential problems promptly and take corrective measures, reducing the likelihood of failure.
