Description

Technical Field

[0001] This utility model relates to the field of door joint bearing technology, and in particular to a door joint bearing anti-sway component. Background Technology

[0002] In the transmission system of automotive doors, the spherical bearing is a key component for enabling the smooth opening and closing of the door, and its stability directly affects the user experience and lifespan of the door. The development of a door spherical bearing anti-sway component aims to solve the swaying problem caused by structural defects in door spherical bearings during long-term use, thereby improving the reliability of door operation.

[0003] In the existing technology, most door joint bearings adopt traditional sliding bearings or simple rolling bearing structures. Their technical principle is to achieve multi-angle rotation through the cooperation of the inner and outer rings of the bearing, and to control the fit clearance by relying on the machining accuracy of the parts, thereby ensuring the flexibility of the door movement.

[0004] However, existing technologies have significant shortcomings: due to factors such as vibration and wear of parts during vehicle operation, the clearance of the joint bearing will gradually increase, causing the door joint bearing to wobble significantly due to clearance or wear, which seriously affects the stability of the door operation and reduces the operational reliability and service life of the door joint bearing. Therefore, a door joint bearing anti-sway component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a door joint bearing anti-sway component, which aims to improve the problem that due to factors such as vibration and wear of parts during vehicle operation, the clearance of the joint bearing will gradually increase, causing the door joint bearing to wobble significantly due to clearance or wear, which seriously affects the stability of the door operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a door joint bearing anti-sway assembly, comprising a bushing and a ball head, wherein the sidewall of the ball head is rotatably connected inside the bushing, and the sidewall of the bushing is provided with an anti-sway mechanism; The anti-sway mechanism includes a cover ring plate and multiple limiting balls. The end of the bushing is provided with a slot. The cover ring plate is connected to the bushing by screws. The cover ring plate is provided with ball holes that are adapted to the limiting balls. The limiting balls are disposed inside the slot and partially accommodated in the ball holes to limit the sway of the ball head.

[0007] As a further description of the above technical solution: The anti-sway mechanism also includes a sealing ring, which is disposed between the bushing and the cover ring plate to achieve a seal between the cover ring plate and the bushing. The bushing and the cover ring plate are both provided with grooves that match the sealing ring.

[0008] As a further description of the above technical solution: A washer is provided between the screw and the cover ring plate to enhance the stability of the screw.

[0009] As a further description of the above technical solution: The cover ring plate is provided with a lubrication mechanism, which includes an oil reservoir and multiple oil outlet holes. The oil reservoir is located on the inner side of the cover ring plate, and the oil outlet holes are connected to the oil reservoir and the ball bearing hole to supply lubricant to the limiting ball bearing.

[0010] As a further description of the above technical solution: The lubrication mechanism further includes an oil injection head and a cover. The oil injection head is disposed on the cover ring plate and communicates with the oil reservoir. The cover is detachably threaded to the oil injection head.

[0011] As a further description of the above technical solution: The oil outlet is conical and a sponge pad is provided inside the oil outlet. The sponge pad is used to absorb and slowly release the lubricant in the oil storage tank.

[0012] As a further description of the above technical solution: The sponge pad is made of oil-resistant polyurethane sponge and elastically abuts against the limiting ball.

[0013] As a further description of the above technical solution: The number of limiting balls is six, and they are evenly distributed along the circumference of the ball head.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the rolling support of the limiting ball in the anti-sway mechanism, together with the cover ring plate and the slot, drives the ball head to achieve all-round anti-sway, thereby suppressing the shaking of the door joint bearing and improving the stability of the door operation. This solves the problem that the existing door joint bearing is prone to shaking due to gaps or wear. The above structure improves the operational reliability and service life of the door joint bearing.

[0015] 2. In this utility model, through the cooperation of the oil reservoir, oil outlet and sponge pad in the lubrication mechanism, the lubricant is continuously and slowly released to the contact surface of the limiting ball and the ball head and bushing, thereby achieving long-term lubrication and reducing friction and wear. This solves the problem that the existing door joint bearing is prone to wear and increased shaking due to insufficient lubrication. The above structure improves the wear resistance of the door joint bearing and the stability of the anti-shaking mechanism. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-7The present invention provides an embodiment of a door joint bearing anti-sway assembly, comprising a bushing 1 and a ball head 2. The bushing 1 is made of high-strength wear-resistant alloy material and serves to provide a stable rotational support base for the ball head 2, reducing wear during rotation. The side wall of the ball head 2 is rotatably connected to the inside of the bushing 1. The ball head 2 and the bushing 1 cooperate to perform multi-angle rotational movements, achieving the effect of meeting the different opening and closing angle requirements of the door. The side wall of the bushing 1 is provided with an anti-sway mechanism 3.

[0020] The anti-sway mechanism 3 includes a cover ring plate 301 and multiple limiting balls 302. A groove 303 is provided at the end of the bushing 1. The cover ring plate 301 is connected to the bushing 1 by screws 305 (M5×12 Phillips head countersunk screws) to firmly fix the cover ring plate 301 to the bushing 1, preventing loosening during assembly operation. The cover ring plate 301 has ball holes adapted to the limiting balls 302. The limiting balls 302 are located inside the groove 303 and partially accommodated within the ball holes. The limiting balls 302 limit the radial displacement of the ball head 2. Through cooperation with the groove 303 and the ball holes, the sway amplitude of the ball head 2 during rotation is effectively reduced, improving the stability when the door is opened and closed. The anti-sway mechanism 3 also includes a sealing ring 304, which is located between the bushing 1 and the cover ring plate 301. The sealing ring 304 is used to block external dust. The moisture entering the component helps protect the mating surfaces of the bushing 1 and the ball head 2, extending the component's service life. Both the bushing 1 and the cover ring 301 have grooves matching the sealing ring 304. These grooves position the sealing ring 304, preventing it from shifting during assembly or use and ensuring a tight seal. A washer 306, made of spring steel, is placed between the screw 305 and the cover ring 301 to increase the contact area, distribute the pressure of the screw 305 on the cover ring 301, and prevent the screw 305 from loosening, thus strengthening its stability. Six limiting balls 302, evenly distributed around the circumference of the ball head 2, are made of high-strength bearing steel, applying a uniform limiting force from the circumference of the ball head 2 to multiple points, further enhancing the anti-sway effect.

[0021] The cover ring plate 301 is internally equipped with a lubrication mechanism 4, which includes an oil reservoir 401 and multiple oil outlet holes 402. The oil reservoir 401 is located on the inner side of the cover ring plate 301 and is used to store lubricant, ensuring a continuous supply of lubricant to the oil outlet holes 402. This prevents the limiting balls 302 from experiencing accelerated wear due to lack of lubrication. The oil outlet holes 402 connect the oil reservoir 401 and the ball holes, and are used to transport the lubricant in the oil reservoir 401 to the ball holes to supply lubricant to the limiting balls 302. The oil outlet holes 402 are conical, and this conical structure ensures efficient oil discharge during ball compression, while also ensuring that the lubricant acts continuously and stably on the limiting balls 302, thereby improving lubricant utilization. The oil outlet 402 is equipped with a sponge pad 405, which absorbs and slowly releases the lubricant in the oil reservoir 401. By absorbing a certain amount of lubricant and then slowly releasing it, the lubrication cycle is extended and the frequency of oiling operations is reduced. The sponge pad 405 is made of oil-resistant polyurethane sponge, which has good oil resistance and elasticity. It is not easily damaged in the environment of long-term contact with lubricant and can always keep in close contact with the limiting ball 302 and elastically abut against the limiting ball 302. The sponge pad 405 and the limiting ball 302 cooperate to rotate synchronously, so as to evenly apply lubricant during the rotation of the limiting ball 302 and ensure that all parts of the limiting ball 302 are fully lubricated.

[0022] The lubrication mechanism 4 also includes an oil injection head 403 and a cover 404. The oil injection head 403 is mounted on the cover ring plate 301 and communicates with the oil reservoir 401. The oil injection head 403 is an M8 standard grease nipple oil injection head, which provides a convenient interface for adding lubricant to the oil reservoir 401, making it convenient for operators to use oiling equipment for oiling operations. The cover 404 is detachably threaded onto the oil injection head 403. The cover 404 is used to seal the opening of the oil injection head 403 to prevent external dust and impurities from entering the oil reservoir 401 through the oil injection head 403 and contaminating the lubricant, thereby ensuring the cleanliness of the lubricant and maintaining the lubrication effect.

[0023] Working principle: During operation, when the ball head 2 rotates, multiple limiting balls 302 are evenly distributed in the gap between the ball head 2 and the bushing 1. Through the rolling contact between the balls and the surface of the ball head 2, a multi-point support structure is formed. This structure limits the radial wobble of the ball head 2 on the one hand, and constrains the axial movement of the ball head 2 through the cooperation of the cover ring plate 301 and the slot 303, thereby achieving all-round anti-wobbling of the ball head 2. The sealing ring 304 is set in the groove between the bushing 1 and the cover ring plate 301, which can prevent external dust and moisture from entering the bearing and avoid the wear of components from aggravating the wobble. The screw 305 and the washer 306 fasten the cover ring plate 301 to the slot 303 of the bushing 1 to ensure the structural stability of the anti-wobbling mechanism 3 and further enhance the anti-wobbling effect.

[0024] Lubricant is injected into the oil reservoir 401 through the grease injection head 403. The cover 404 is threaded onto the grease injection head 403 to prevent lubricant leakage or impurities from entering. The lubricant in the oil reservoir 401 is supplied to the limiting ball 302 through the oil outlet 402. The sponge pad 405 in the oil outlet 402 is made of oil-resistant polyurethane sponge material, which can absorb and store a large amount of lubricant. When the ball head 2 drives the limiting ball 302 to rotate, the ball squeezes the sponge pad 405, so that the lubricant is evenly and slowly released onto the contact surface between the ball and the ball head 2 and the bushing 1, achieving continuous lubrication, reducing friction and wear, and indirectly maintaining the stability of the anti-sway mechanism 3.
