Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a universal adjustment connector for a stabilizer bar ball joint pin. Background Technology

[0002] The function of a stabilizer bar is to improve the rigidity of the vehicle body structure and enhance the stability and balance of the vehicle when cornering. When a car is in motion, the independent suspension has a displacement margin. When the vehicle is turning at high speed or one wheel passes over an obstacle, the vehicle tends to tilt or lean. At this time, the stabilizer bar comes into play to counteract the tilt force, reduce the tilt, maintain the lateral height balance of the vehicle, and improve comfort.

[0003] A search of existing Chinese patent technology reveals "A Car Balance Bar with Injection Molded Inner Liner Structure," publication number "CN208411347U." This device effectively improves the assembly performance between the ball joint and the inner bushing. The inner lining of the bushing has good toughness, allowing adjustment of the fit between the inner bushing and the ball pin, and is easy to assemble. However, in automotive applications, road conditions are relatively complex, which can easily lead to increased wear between the ball joint and the connecting ball joint, reducing their service life. Utility Model Content

[0004] The purpose of this utility model is to provide a universal adjustment connector for the balance bar ball joint pin in order to solve the above-mentioned problems. This improves the problem that in the case of relatively complex road conditions during vehicle movement, wear between the ball joint pin and the connecting ball seat is easily accelerated, which reduces the service life of the ball joint pin and the connecting ball seat.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a universal adjusting connector for a balance bar ball joint pin, comprising: a nut and a ball joint pin body, wherein the nut is connected to the end of the ball joint pin body; a connecting mechanism, wherein the connecting mechanism is sleeved on the surface of the ball joint pin body; wherein the connecting mechanism includes a sleeve assembly sleeved on the surface of the ball joint pin body, a protective assembly is provided on the side of the sleeve assembly near the nut, the protective assembly is connected to the surface of the ball joint pin body, and a lubrication assembly is provided on the side of the sleeve assembly away from the nut.

[0006] Preferably, the fitting assembly includes a connecting ball seat fitted onto the ball portion of the ball head pin. The connecting ball seat has a side annular groove on the side near the nut, and an inner annular groove inside the connecting ball seat, communicating with the side annular groove. A retaining spring is disposed inside the side annular groove and engages with the inner wall of the inner annular groove. The ball portion of the ball head pin contacts the inner wall of the connecting ball seat.

[0007] Preferably, the connecting ball seat has a circular hole on the side away from the nut, the circular hole communicating with the interior of the connecting ball seat, and the interior of the connecting ball seat has a threaded groove extending to the side of the connecting ball seat away from the nut. A portion of grease is filled inside the circular hole, which is in communication with the interior of the connecting ball seat.

[0008] Preferably, the lubrication assembly includes a threaded cap threaded to the inner wall of a threaded groove, a round rod fixedly connected to the inner wall of the threaded cap, and a piston fixedly connected to the other end of the round rod. The piston is slidably connected to the inner wall of a round hole. The piston pushes the grease inside the round hole towards the ball of the ball joint pin.

[0009] Preferably, a brush bristle is fixedly connected to the side of the piston away from the threaded cap, and the surface of the brush bristle contacts the ball portion of the ball head pin. The contact between the brush bristle and the ball portion of the ball head pin helps to apply lubricant to the surface of the ball head pin.

[0010] Preferably, the sleeve assembly includes a collar fixedly connected to the rod portion of the ball head pin, a first connecting ring fixedly connected to the inner wall of the collar, and a rubber sleeve fixedly connected to the surface of the first connecting ring. The connecting ball seat is sleeved on the ball portion of the ball head pin, reducing the entry of external impurities into the contact surface between the ball portion of the ball head pin and the connecting ball seat.

[0011] Preferably, a second connecting ring is fixedly connected to the end of the rubber sleeve away from the first connecting ring. The second connecting ring is located inside the side ring groove, and the surface of the second connecting ring engages with the surface of the retaining spring. The retaining spring engages with the inner ring groove, preventing the second connecting ring from easily falling off.

[0012] Beneficial effects

[0013] The universal adjustment connector of the balance bar ball joint, by setting up a sleeve component and a lubrication component, allows the ball joint to rotate inside the connecting ball seat. The piston pushes the grease inside the round hole to the ball part of the ball joint, providing auxiliary lubrication to the surface of the ball joint. Furthermore, the brush bristles contact the ball part of the ball joint to help apply the grease to the surface of the ball joint, thereby reducing wear and extending its service life.

[0014] By setting up a sleeve component and a protective component, under the combined action of the sleeve component and the protective component, the connecting ball seat is sleeved on the ball part of the ball head pin body. The second connecting ring is located inside the side ring groove and is engaged with the snap ring at the inner ring groove, so that the second connecting ring will not easily fall off. This reduces the entry of external impurities into the contact surface between the ball part of the ball head pin body and the connecting ball seat, reduces the impact of external impurities on the wear of the ball head pin body, and extends its service life.

[0025] The following is combined with Figures 1-4 This invention describes the universal adjusting connector for the balance bar ball joint pin.

[0026] In one embodiment, a universal adjustment connector for a balance bar ball joint pin includes: a nut 1 and a ball joint pin 2, the nut 1 being connected to the end of the ball joint pin 2; a connecting mechanism 3 being sleeved on the surface of the ball joint pin 2; wherein, the connecting mechanism 3 includes a sleeve assembly 31 sleeved on the surface of the ball joint pin 2, a protective assembly 33 being provided on the side of the sleeve assembly 31 near the nut 1, the protective assembly 33 being connected to the surface of the ball joint pin 2, and a lubrication assembly 32 being provided on the side of the sleeve assembly 31 away from the nut 1;

[0027] It should be noted that the surface of the connecting ball joint 311 is connected to a stabilizer bar. The stabilizer bar is a major component of the car suspension system, mainly designed to maintain the stability of the vehicle body on uneven roads or during high-speed cornering. The ball joint pin 2 is connected to the suspension control arm of the vehicle frame.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the sleeve assembly 31 includes a connecting ball seat 311 sleeved on the ball part of the ball head pin 2. The connecting ball seat 311 has a side annular groove 312 on the side near the nut 1. The connecting ball seat 311 has an inner annular groove 313 inside, which communicates with the side annular groove 312. A retaining spring 314 is provided inside the side annular groove 312 and is engaged with the inner wall of the inner annular groove 313. The connecting ball seat 311 has a circular hole 315 on the side away from the nut 1, which communicates with the inside of the connecting ball seat 311. The connecting ball seat 311 has a threaded groove 316 inside, which extends to the side of the connecting ball seat 311 away from the nut 1.

[0029] The lubrication assembly 32 includes a threaded cap 321 threaded to the inner wall of the threaded groove 316, a round rod 322 fixedly connected to the inner wall of the threaded cap 321, a piston 323 fixedly connected to the other end of the round rod 322, the piston 323 slidably connected to the inner wall of the round hole 315, and a bristle 324 fixedly connected to the side of the piston 323 away from the threaded cap 321, the surface of the bristle 324 contacting the ball part of the ball head pin 2;

[0030] In this embodiment, the device enters the threaded groove 316 through the screw on the threaded cap 321, causing the round rod 322 to gradually extend into the round hole 315. Since the round hole 315 is connected to the ball seat 311, some grease can be filled inside the round hole 315. When the round rod 322 approaches the ball head pin 2, the piston 323 pushes the grease inside the round hole 315 to the ball part of the ball head pin 2, which provides auxiliary lubrication to the surface of the ball head pin 2. The grease will also come into contact with the bristles 324. Through the contact between the bristles 324 and the ball part of the ball head pin 2, the grease is applied to the surface of the ball head pin 2, thereby reducing the wear of the ball head pin 2.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the sleeve assembly 31 includes a collar 334 fixedly connected to the rod of the ball head pin 2. A first connecting ring 332 is fixedly connected to the inner wall of the collar 334. A rubber sleeve 331 is fixedly connected to the surface of the first connecting ring 332. A second connecting ring 333 is fixedly connected to the end of the rubber sleeve 331 away from the first connecting ring 332. The second connecting ring 333 is located inside the side ring groove 312. The surface of the second connecting ring 333 engages with the surface of the retaining spring 314.

[0032] In this embodiment, the connecting ball seat 311 is sleeved on the ball part of the ball head pin 2, which reduces the entry of external impurities into the contact surface between the ball part of the ball head pin 2 and the connecting ball seat 311, thereby reducing the wear of the ball head pin 2. Furthermore, the second connecting ring 333 is located inside the side ring groove 312 and is engaged with the snap ring 314 at the inner ring groove 313, so that the second connecting ring 333 will not easily fall off, ensuring a good protective effect on the ball part of the ball head pin 2 and reducing the impact of external impurities on the wear of the ball head pin 2.

[0033] Working principle: Manually turn the screw cap 321 into the threaded groove 316. The round rod 322 gradually extends into the round hole 315. The round hole 315 communicates with the inside of the connecting ball seat 311. The round hole 315 is filled with some grease. When the round rod 322 approaches the ball head pin 2, the piston 323 pushes the grease inside the round hole 315 to the ball part of the ball head pin 2. The surface of the ball head pin 2 is coated with auxiliary lubricant. The bristles 324 contact the ball part of the ball head pin 2 to apply grease to the surface of the ball head pin 2. The connecting ball seat 311 is fitted onto the ball part of the ball head pin 2 to reduce the entry of external impurities into the contact surface between the ball part of the ball head pin 2 and the connecting ball seat 311. The second connecting ring 333 is located inside the side ring groove 312 and is engaged with the snap ring 314 at the inner ring groove 313. The second connecting ring 333 will not easily fall off, ensuring a good protection effect for the ball part of the ball head pin 2.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
