Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a wear-resistant injection-molded ball joint fixing device for automotive steering systems. Background Technology

[0002] With the rapid development of the automotive industry, vehicle handling performance, reliability, and service life are receiving increasing attention. As a key component of the vehicle chassis, the steering system's performance directly affects the vehicle's driving stability and safety. The ball joint (or ball pin) is an important connecting component in the steering system (such as the tie rod and stabilizer bar linkage), responsible for transmitting steering force and allowing the connecting components to rotate in multiple directions within a certain angle range. During long-term steering and suspension movements, the ball joint frequently rotates and oscillates relative to the socket, enduring significant friction and impact, making it one of the most easily worn components.

[0003] Traditional automotive steering systems use ball joint mounting devices, which typically employ a metal ball joint and ball head assembly. While these devices offer good wear resistance, they are prone to problems such as accelerated wear, increased clearance, and abnormal noises under prolonged use, poor lubrication, or dust intrusion. In severe cases, they can even lead to loose steering, loss of control, and safety hazards. Furthermore, the connection between the ball head and ball joint is complex and difficult to disassemble and maintain, and the ball head can be damaged if not handled carefully.

[0004] Furthermore, traditional lubrication methods often involve one-time grease application or periodic manual application via external grease fittings. These methods suffer from inconsistent lubrication, susceptibility to contamination, and inconvenient maintenance, making long-term lubrication difficult. Simultaneously, under harsh operating conditions, friction between the ball joint and the socket generates heat, accelerating lubricant aging and failure, thus exacerbating wear. While some injection-molded ball joints utilizing the self-lubricating properties of engineering plastics have emerged, their structural design, lubrication system integration, and heat dissipation performance remain inadequate. They often lack efficient automatic lubrication and cooling mechanisms, failing to meet the demands of modern automobiles for high performance, high durability, and low maintenance costs.

[0005] Therefore, there is an urgent need to develop a new type of ball-and-socket fixing device for automotive steering systems that is more wear-resistant, has long-lasting and intelligent lubrication capabilities, can effectively dissipate heat, and is easy to maintain, in order to solve the technical problems existing in the current technology, such as unsustainable lubrication, poor heat dissipation, susceptibility to external contamination, and inconvenient maintenance, thereby improving the overall reliability and service life of the steering system.

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 11As shown, a wear-resistant injection-molded ball socket fixing device for an automotive steering system according to the present invention includes a connecting rod 1, a fixing seat 2 welded to one end of the connecting rod 1, a movable mechanism 3 mounted on the fixing seat 2, the movable mechanism 3 including a ball socket 306, the ball socket 306 being installed inside the fixing seat 2, a ball head 302 being rolledly connected to the ball socket 306, a fixing rod 301 welded to the top of the ball head 302, the fixing rod 301 extending to the outer side of one end of the fixing seat 2, and a lubrication mechanism 5 and a heat dissipation mechanism 8 mounted on the fixing seat 2.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting groove 305 is provided at the center of one end of the fixing base 2. The ball socket 306 engages with the inner bottom of the mounting groove 305. A pressure sleeve 303 is threadedly connected to the top of the fixing base 2. The bottom of the pressure sleeve 303 abuts against the top edge of the ball socket 306. Multiple annularly distributed grooves 304 are provided on the outer edge of the top of the pressure sleeve 303. Multiple equally distributed through grooves 307 are provided on the edge of the ball socket 306. The mounting groove 305 facilitates the engagement and installation of the ball socket 306. Combined with the connection of the pressure sleeve 303, this achieves the desired fit. The ball socket 306 is securely installed, allowing the ball head 302 to roll within it and change direction. Multiple grooves 304 facilitate the use of a wrench to drive and control the pressure sleeve 303, enabling its installation and removal. This also facilitates the disassembly and maintenance of the ball socket 306. A through groove 307 on the outer edge of the ball socket 306 provides some elasticity, aiding in the installation and removal of the ball head 302. The pressure sleeve 303 abuts against the ball head 302, preventing disassembly.

[0037] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the lubrication mechanism 5 includes a connecting block 501. The other end of the fixed base 2 is threadedly connected to the connecting block 501. One end of the connecting block 501 is provided with an oil supply hole 502. The inside of the connecting block 501 is provided with an oil storage groove 504. A connecting pipe 503 is connected to the center of the outer side of the ball socket 306. One end of the connecting pipe 503 extends to the outside of the ball socket 306, and the other end of the connecting pipe 503 extends to the outside of the connecting block 501 and engages with the oil supply hole 502. The opening of the oil storage groove 504 facilitates the addition of lubricating oil to the inside of the oil storage groove 504 through the oil supply hole 502. After the connecting block 501 is installed, the lubricating oil is introduced into the inside of the connecting pipe 503 through the oil supply hole 502, and then into the inner wall of the ball socket 306 through the connecting pipe 503, thereby lubricating the ball head 302, reducing friction, and extending its service life.

[0038] Specifically, such as Figure 6 andFigure 10 As shown, the outer side of the connecting block 501 is provided with a hexagonal drive groove 505, and the inner sidewall of the ball socket 306 is provided with multiple arc-shaped guide grooves 506. One end of each of the multiple guide grooves 506 extends to the end of the connecting pipe 503. A sealing ring 507 is installed on the outer sidewall of the connecting block 501. The sealing ring 507 abuts against the inner sidewall of the fixing seat 2. The opening of multiple guide grooves 506 facilitates the even distribution of lubricating oil to the sidewall of the ball socket 306, resulting in good lubrication and preventing leakage. The opening of the drive groove 505 makes it easy to drive and control the connecting block 501 with a wrench, making operation convenient. The installation of the sealing ring 507 ensures good sealing between the connecting block 501 and the fixing seat 2, preventing oil leakage.

[0039] Specifically, such as Figure 6 and Figure 7 As shown, a control mechanism 6 is installed inside the fixed base 2. The control mechanism 6 includes a plug 601. The plug 601 is installed inside the oil storage tank 504. One end of the plug 601 is slidably connected to the inside of the oil storage tank 504 through a memory spring 602. The plug 601 has a "T" shaped structure, and the end of the plug 601 has a frustum-shaped structure. One end of the plug 601 is engaged with the inside of the oil delivery hole 502. An annular heat-conducting sleeve 603 is installed on the inner side of the end of the connecting block 501. One end of the heat-conducting sleeve 603 is connected to the end of the memory spring 602. The installation of the memory spring 602 facilitates the connection of the plug 601. Pulled by 2, one end of the plug 601 is inserted into the oil inlet 502, and the lubricating oil in the oil reservoir 504 cannot be discharged. When the heat inside the fixed seat 2 increases, the heat is transferred to the inside of the connecting block 501. When the heat reaches a certain value, the memory spring 602 returns to its initial state and then resists the plug 601. The plug 601 separates from the oil inlet 502, which facilitates the discharge of oil from the oil reservoir 504 and realizes lubrication between the ball head 302 and the ball socket 306. With the cooperation of the heat-conducting sleeve 603, the heat is better transferred to the memory spring 602, making the memory spring 602 move more sensitively.

[0040] Specifically, such as Figure 6As shown, a contact mechanism 7 is installed inside the fixed base 2. The contact mechanism 7 includes a baffle 702. The baffle 702 is slidably connected inside the oil storage tank 504. A compression spring 701 is connected to the center of the inner side of the oil storage tank 504 on one side of the baffle 702. A sealing gasket 703 is installed on the other side of the baffle 702. The sealing gasket 703 is slidably connected to the inner wall of the oil storage tank 504. With the installation of the baffle 702 and the cooperation of the compression spring 701, the baffle 702 slides to one side inside the oil storage tank 504, which facilitates the output of lubricating oil into the oil delivery hole 502. With the cooperation of the sealing gasket 703, the oil inside the oil storage tank 504 is better squeezed out. By disassembling the connecting block 501, it is easy to insert an external oil pipe into the oil delivery hole 502 to realize the filling of oil into the oil storage tank 504 and drive the baffle 702 to slide away from the elastic force of the compression spring 701 to realize the storage of oil.

[0041] Specifically, such as Figure 1 , Figure 5 and Figure 8 As shown, a protective mechanism 4 is installed on the fixing rod 301. The protective mechanism 4 includes a dust cover 401. The dust cover 401 is provided on the outside of the fixing rod 301. The dust cover 401 has a conical structure and a corrugated structure on the outside. One end of the dust cover 401 is connected to the outside of the fixing rod 301, and the other end of the dust cover 401 is connected to the pressure sleeve 303. The installation of the dust cover 401 helps to shield and protect the outside of the pressure sleeve 303, preventing dust and debris from entering the ball head 302 and causing the ball head 302 and the ball socket 306 to jam, thus affecting the service life.

[0042] Specifically, such as Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, the outer side of the fixing rod 301 is provided with an annular groove 402. A rubber ring 403 is installed on the inner side wall of one end of the dust cover 401. The rubber ring 403 is a hollow annular structure. The outer side of the rubber ring 403 engages with the inside of the groove 402. Multiple magnetic blocks 404 are installed at the other end of the dust cover 401 in an annular and equidistant arrangement. The magnetic blocks 404 engage with the inside of the grooves 304. The groove 402 facilitates the engagement of one end of the dust cover 401 with the groove 402 via the rubber ring 403, thus enabling the dust cover 401 to be mounted on the fixing rod 301. The rubber ring 403 is elastic, engages tightly with the groove 402, and is easy to install and remove. The engagement of multiple magnetic blocks 404 with multiple grooves 304 ensures a firm connection between the dust cover 401 and the pressure sleeve 303, while also facilitating installation and removal.

[0043] Specifically, such as Figure 1 , Figure 2 and Figure 11As shown, the heat dissipation mechanism 8 includes a heat dissipation plate 801. The heat dissipation plate 801 is located at the center of the end of the fixed base 2. The heat dissipation plate 801 is detachably connected to the end of the fixed base 2 via a connecting block 501. Multiple ventilation slots 804 arranged in a ring are provided at the edge of the heat dissipation plate 801. The heat dissipation plate 801 is installed by the cooperation of the connecting block 501, which facilitates the heat dissipation of the fixed base 2. The heat dissipation effect of the heat dissipation plate 801 is accelerated by the cooperation of the multiple ventilation slots 804. The heat dissipation plate 801 can be disassembled and maintained by removing the connecting block 501.

[0044] Specifically, such as Figure 4 and Figure 11 As shown, the inner side of one end of the fixed base 2 is provided with a plurality of positioning grooves 802 arranged in a ring at equal intervals. A plurality of heat-conducting rods 803 arranged in a ring at equal intervals are vertically connected to one side of the heat sink 801. The plurality of heat-conducting rods 803 are slidably connected to the interior of the plurality of positioning grooves 802. The opening of the plurality of positioning grooves 802 facilitates the insertion of the plurality of heat-conducting rods 803, thereby achieving the positioning function of the heat sink 801. At the same time, it facilitates the transfer of heat inside the fixed base 2 to the heat sink 801 through the heat-conducting rods 803, thereby increasing the heat dissipation effect.

[0045] In use, the present invention firstly facilitates the engagement and installation of the ball socket 306 through the opening of the mounting groove 305, and with the connection of the pressure sleeve 303, ensures a secure installation of the ball socket 306, allowing the ball head 302 to roll within the ball socket 306 and change direction. The cooperation of multiple grooves 304 facilitates the drive control of the pressure sleeve 303 via a wrench, enabling the installation and removal of the pressure sleeve 303, thus facilitating the disassembly and maintenance of the ball socket 306. The through groove 307 on the outer edge of the ball socket 306 provides a certain degree of elasticity, facilitating the installation and removal of the ball head 302. The pressure sleeve 303 abuts against the ball head 302, preventing disassembly. The oil reservoir 504 facilitates the flow of oil through the oil inlet 502 into the oil reservoir 504. Lubricating oil is added to the ball joint. After the connecting block 501 is installed, the lubricating oil is introduced into the connecting pipe 503 through the oil inlet 502, and then into the inner wall of the ball socket 306 through the connecting pipe 503, thereby lubricating the ball head 302, reducing friction, and extending service life. The opening of multiple guide grooves 506 facilitates the even distribution of lubricating oil to the side wall of the ball socket 306, resulting in good lubrication and preventing leakage. The opening of the drive groove 505 facilitates the use of a wrench to drive and control the connecting block 501, making operation convenient. The installation of the sealing ring 507 ensures good sealing between the connecting block 501 and the fixed seat 2, preventing oil leakage. The installation of the memory spring 602 facilitates the connection of the plug 601. Under the pull of the memory spring 602, one end of the plug 601... When the lubricating oil is inserted into the oil inlet 502, the lubricating oil inside the oil reservoir 504 cannot be discharged. When the heat inside the fixed seat 2 increases, the heat is transferred to the connecting block 501. When the heat reaches a certain value, the memory spring 602 returns to its initial state, thus resisting the plug 601. The plug 601 separates from the oil inlet 502, facilitating the discharge of oil from the oil reservoir 504 and achieving lubrication between the ball head 302 and the ball socket 306. Through the cooperation of the heat-conducting sleeve 603, the heat is better transferred to the memory spring 602, making the memory spring 602 more sensitive. Through the installation of the baffle 702, with the cooperation of the compression spring 701, the baffle 702 slides to one side inside the oil reservoir 504, which facilitates the discharge of lubricating oil into the oil inlet 502. With the cooperation of the sealing gasket 703, the oil inside the oil storage tank 504 is better pressed out. By disassembling the connecting block 501, it is easy to insert the external oil pipe into the oil delivery hole 502 to realize the filling of oil into the oil storage tank 504. It also drives the baffle 702 to slide away from the elastic force of the compression spring 701 to realize oil storage. The installation of the dust cover 401 helps to shield and protect the outside of the pressure sleeve 303, preventing dust and debris from entering the ball head 302 and causing the ball head 302 and the ball socket 306 to jam, affecting the service life. The opening of the slot 402 facilitates the engagement of one end of the dust cover 401 with the slot 402 through the rubber ring 403, so that the end of the dust cover 401 is installed on the fixing rod 301. The rubber ring 403 is elastic and engages tightly with the slot 402.Furthermore, it is easy to assemble and disassemble. Multiple magnetic blocks 404 engage with multiple grooves 304 to securely connect the dust cover 401 to the pressure sleeve 303, while also facilitating disassembly and assembly. The connecting block 501 facilitates the installation of the heat sink 801, promoting heat dissipation from the mounting base 2. Multiple ventilation slots 804 accelerate the heat dissipation of the heat sink 801. Disassembling the connecting block 501 allows for easy removal and maintenance of the heat sink 801. Multiple positioning slots 802 facilitate the insertion of multiple heat-conducting rods 803, positioning the heat sink 801 and allowing for better heat transfer from inside the mounting base 2 to the heat sink 801 via the heat-conducting rods 803, thus enhancing the heat dissipation effect.
