Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and particularly relates to an adjusting arm clutch ring component. Background Art

[0002] The adjusting arm clutch ring assembly is a component of the automobile clearance adjusting arm, which plays the role of clutch.

[0003] When in use, the adjusting arm clutch ring assembly is unidirectionally controlled by the principle of contraction of the forward teeth and expansion of the reverse teeth of the torsion spring. Stable locking torque is the key to ensuring product reliability. The existing clutch ring inner gear ring has a small number of teeth, which results in a small locking torque and an unstable connection. At the same time, the sealing performance at the connection with the clutch gear is poor. After long-term use, dust is easily introduced into the interior, affecting the service life. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to provide an adjusting arm clutch ring assembly with increased locking torque, more stable connection, better sealing performance and longer service life.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an adjusting arm clutch ring assembly, including a clutch gear, a clutch torsion spring is placed on the right side of the inner cavity of the clutch gear, a clutch ring body is sleeved on the right side of the surface of the clutch torsion spring, the clutch ring body includes an outer shell, an inner cavity of the outer shell is provided with an inner gear ring, and a connecting gear is fixedly connected to the right side of the inner cavity of the outer shell.

[0006] The clutch ring assembly of the adjusting arm is mainly provided with a clutch gear, a clutch torsion spring, a clutch ring body, a sealing insert ring, grease and a plug-in slide groove on a bottom plate. The clutch gear, the clutch torsion spring, the clutch ring body, the sealing insert ring, grease and the plug-in slide groove can increase the locking torque, make the connection more stable, achieve better sealing performance and extend the service life.

[0007] In the above-mentioned adjusting arm clutch ring assembly, a first mounting groove is provided on the right side of the inner cavity of the clutch gear, and a second mounting groove is provided on the left side of the clutch ring body. In practical applications, by providing the first mounting groove and the second mounting groove, the function of convenient installation is provided, and the clutch torsion spring can be conveniently installed in the clutch gear and the clutch ring body.

[0008] In the above-mentioned adjusting arm clutch ring assembly, a sealing insert is fixedly connected to the left side of the outer surface of the clutch ring body, and a protective shell is sleeved on the outer surface of the clutch gear. In practical applications, the sealing insert is an ultra-high molecular polyethylene plate with good wear resistance and corrosion resistance.

[0009] In the above-mentioned adjusting arm clutch ring assembly, a plug-in slot is provided at the edge of the right side of the protective shell, and the left side of the sealing insert ring extends to the inner cavity of the plug-in slot. In practical applications, the plug-in slot is provided with a plug-in connection function, and the sealing insert ring can be conveniently inserted into the interior thereof to improve the sealing performance.

[0010] In the above-mentioned adjusting arm clutch ring assembly, the inner cavity of the plug-in slide is filled with grease, and a silicone ring is fixedly connected to the right side of the inner cavity of the plug-in slide. In practical applications, the silicone ring is provided to improve the dust blocking function, and can slide in contact with the sealing plug ring, effectively preventing external dust from entering the plug-in slide.

[0011] Compared with the prior art, the advantages of the adjusting arm clutch ring assembly are: the locking torque is increased during operation, the connection is more stable, the sealing performance is better, and the service life is extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the adjusting arm clutch ring assembly includes a clutch gear 1, a clutch torsion spring 2 is placed on the right side of the inner cavity of the clutch gear 1, a clutch ring body 3 is sleeved on the right side of the surface of the clutch torsion spring 2, the clutch ring body 3 includes an outer shell 5, an inner cavity of the outer shell 5 is provided with an inner gear ring 6, and a connecting gear 7 is fixedly connected to the right side of the inner cavity of the outer shell 5.

[0020] A first mounting groove 11 is provided on the right side of the inner cavity of the clutch gear 1, and a second mounting groove 12 is provided on the left side of the clutch ring body 3. A sealing insert ring 4 is fixedly connected to the left side of the outer surface of the clutch ring body 3, and a protective shell 13 is provided on the outer surface of the clutch gear 1.

[0021] A plug-in slot 9 is provided at the right edge of the protective shell 13, and the left side of the sealing insert ring 4 extends to the inner cavity of the plug-in slot 9. The inner cavity of the plug-in slot 9 is filled with grease 8, and a silicone ring 10 is fixedly connected to the right side of the inner cavity of the plug-in slot 9.

[0022] During actual manufacturing, the clutch torsion spring 2 is first installed in the first installation groove 11, and then the clutch ring body 3 is sleeved on the outer surface of the clutch torsion spring 2. At this time, the clutch torsion spring 2 and the inner gear ring 6 have an interference fit. At this time, the number of teeth of the inner gear ring 6 is increased, and the original inner gear ring 6 is optimized from thirty-six teeth to fifty teeth. This can increase the interference contact surface and thus increase its locking torque. During the assembly process, first apply grease 8 to the plug-in groove 9, and then insert the sealing plug ring 4 on the outer surface of the clutch ring body 3 into the plug-in groove 9 on the right side of the protective shell 13, and then assemble it. In this way, the surface of the sealing plug ring 4 after being inserted into the plug-in groove 9 contacts with the grease 8, which can effectively prevent external dust from entering the interior from the connection between the clutch gear 1 and the clutch ring body 3, and the sealing effect is poor, thereby extending its service life.
