Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive transmission technology, specifically relating to a clutch control system. Background Technology
[0002] The release arm is a crucial component of the transmission clutch control system. One end of the release arm connects to the clutch slave cylinder or clutch cable, while the other end connects to the release bearing assembly, using a stud as a fulcrum for oscillation. When the vehicle's power steering components apply force to one end of the release arm, it begins to oscillate, thus achieving clutch disengagement and engagement. Because the release arm has numerous connections with other components, it is prone to problems such as abnormal noise and vibration. For example, when one end of the release arm is subjected to force within the vehicle's structure, and the other end pushes the release bearing assembly axially, abnormal noises are likely to occur at the points where the release arm connects to the clutch slave cylinder push rod and the points where it mates with the release bearing assembly. Therefore, a well-designed release arm structure is essential. Utility Model Content
[0003] In order to effectively improve the problem of abnormal noise during operation of the release arm and make its working state more stable and reliable, this utility model provides a noise reduction clutch control system.
[0004] The technical solution adopted by this utility model is:
[0005] A noise-reducing clutch control system includes a release arm, a front housing, a stud, a clutch slave cylinder push rod, a release bearing assembly, and a clutch release finger. One end of the release arm has a through hole and is slidably fitted onto a guide sleeve inside the front housing along with the release bearing assembly. The clutch release finger is fixed on the guide sleeve and located below the release bearing assembly. The other end of the release arm extends out of the front housing and abuts against the clutch slave cylinder push rod, which pushes the other end to move. The fulcrum of the release arm is placed on the ball head of the stud. Both the clutch slave cylinder push rod and the stud are mounted on the front housing and are located on the upper and lower sides of the release arm.
[0006] Compared with the prior art, the present invention has the following advantages:
[0007] This invention adds a groove structure at the mating point between the release arm and the release bearing assembly, allowing the applied grease to remain in the groove structure, thus reducing direct metal-to-metal contact between the release arm and the release bearing assembly. A nylon material structure is used at the mating point between the release arm and the clutch slave cylinder push rod to prevent direct metal-to-metal contact between the release arm and the push rod, improving the operating conditions of the release arm and reducing abnormal noise problems in the clutch operating system.
[0008] This invention is easy to implement and has good results. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model will be provided below with reference to the accompanying drawings.
[0015] like Figure 1 As shown, this utility model provides a noise-reducing clutch control system, including a release arm 1, a front housing 2, a stud 3, a clutch slave cylinder push rod 4, a release bearing assembly 5, and a clutch release finger 6. One end of the release arm 1 has a through hole and is slidably fitted onto a guide sleeve inside the front housing 2 along with the release bearing assembly 5. The clutch release finger 6 is fixed on the guide sleeve and located below the release bearing assembly 5. The other end of the release arm 1 extends out of the front housing 2 and abuts against the clutch slave cylinder push rod 4, which pushes the other end of the release arm 1 to move. The fulcrum of the release arm 1 is placed on the ball head of the stud 3. The clutch slave cylinder push rod 4 and the stud 3 are both mounted on the front housing 2, and the clutch slave cylinder push rod 4 and the stud 3 are located on the upper and lower sides of the release arm 1.
[0016] After the initial installation of the release arm 1, release bearing assembly 5, release arm clamp, and stud clamp, the release arm 1 and release bearing assembly 5 are together inserted into the front housing 2 along the guide sleeve of the front housing 2. The ball socket of the release arm 1 is positioned on the ball head of the stud 3, and the middle part of the release arm clamp will clamp the stud 3. The other end of the release arm 1 extends out of the dustproof sleeve, and the clutch slave cylinder push rod 4 extends into the ball socket of the release arm 1 push rod. When the clutch slave cylinder push rod 4 pushes the release arm 1, the release arm 1 drives the release bearing assembly 5 to move downwards along the front housing guide sleeve, causing the working end face of the release bearing to contact the clutch release finger 6, thus achieving clutch engagement and disengagement.
[0017] like Figure 2 , Figure 3As shown, the mating surface of the separation arm 1 and the separation bearing assembly 5 is provided with a groove structure 101 for storing grease, so that the two can maintain lubrication for as long as possible during operation.
[0018] The width of the groove structure 101 needs to be combined with the installation state of the release bearing assembly 5 to ensure that there is a certain amount of lubrication when the two are in contact.
[0019] like Figure 2 , Figure 4 As shown, a nylon structure 102 is embedded in the ball socket of the release arm 1 where it mates with the clutch slave pump push rod 4. This prevents direct metal-to-metal contact between the release arm 1 and the clutch slave pump push rod 4.
[0020] like Figure 4 As shown, a limiting groove 103 is provided on the pusher ball socket of the separation arm 1 to cooperate with the protrusion of the nylon material structure 102 to prevent the nylon material structure 102 from moving.
[0021] The above changes can improve the operating conditions of the release arm 1 and reduce abnormal noise problems in the clutch control system.
[0022] like Figure 3 As shown. The groove structure 101 of the separating support arm 1 is provided with a chamfered structure 104.
