Description

Technical Field

[0001] The invention relates to the technical field of clutches, in particular to an improved clutch push rod assembly. Background Art

[0002] In the design and application of the clutch, the push rod assembly, as one of its key components, undertakes the important task of transmitting thrust and controlling the separation and engagement of the clutch. However, when subjected to high-frequency and high-intensity impacts, the traditional clutch push rod assembly often suffers from wear, deformation, and even breakage, which seriously affects the service life and performance stability of the clutch.

[0003] In order to meet this challenge, the industry has continuously improved and optimized the clutch push rod assembly. However, most of the existing improvement plans focus on improving material strength and optimizing structural design. Although the durability of the push rod assembly has been improved to a certain extent, there are still some problems, such as the push rod is easily deformed when subjected to non-axial forces and the connection structure is not stable enough. Summary of the invention

[0004] In view of the problems existing in the above-mentioned background technology, the present invention aims to propose an innovative solution, namely, an improved clutch push rod assembly.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an improved clutch push rod assembly, comprising a rubber tube and a push rod, the upper end of the rubber tube is connected to a ball sleeve, the top end of the push rod is stuck in the interior of the rubber tube, the top end of the push rod is fixedly connected to an upper sphere, the upper sphere is movably clamped in the interior of the ball sleeve, the outer surface of the upper sphere is fitted with the inner wall of the ball sleeve, a connecting tube is provided below the rubber tube, the center axes of the rubber tube and the connecting tube are located in the same straight line, a connecting piece is provided below the connecting tube, the upper section of the connecting piece is fixedly connected to a limiting sleeve, the lower end of the connecting tube is clamped in the interior of the limiting sleeve, the connecting tube is fixedly connected to the limiting sleeve, the interior of the connecting tube is fixedly connected to a fitting ring, the lower end of the push rod is fixedly connected to a lower sphere, and the lower sphere is movably clamped in the interior of the fitting ring.

[0006] Preferably, the outer surface of the chimeric ring is provided with a plurality of grooves, and the plurality of grooves are distributed in a circular array with the central axis of the chimeric ring as the center.

[0007] Preferably, the rubber tube is compressible.

[0008] Preferably, the size of the upper sphere is larger than that of the lower sphere.

[0009] Preferably, the ball sleeve and the fitting ring are both made of rubber.

[0010] Working principle: When an improved clutch push rod assembly is used, during the working process of the clutch, the push rod, as a core component, receives the thrust from the clutch actuator. This thrust first acts on the upper sphere at the top of the push rod. Due to the movable clamping relationship between the upper sphere and the ball sleeve at the upper end of the rubber tube, the thrust can be smoothly transmitted to the rubber tube. With its compressibility, the rubber tube effectively absorbs and disperses part of the impact energy, providing additional protection for the clutch. Subsequently, the thrust continues to be transmitted to the connecting piece along the central axis of the rubber tube and the connecting tube, and finally acts on other parts of the clutch. During this transmission process, the fixed connection between the connecting tube and the limit sleeve ensures the overall stability of the push rod assembly. When the push rod is subjected to non-axial force, the lower sphere at its lower end can achieve a small angle of free deflection in the chimeric ring. This design benefits from the multiple slots carefully opened on the outer surface of the chimeric ring. These slots are distributed in a circular array with the central axis of the chimeric ring as the center, which not only enhances the connection strength between the rubber tube and the connecting tube, but also improves the structural strength and adaptability of the entire push rod assembly.

[0011] The present invention provides an improved clutch push rod assembly, which has the following beneficial effects: 1. High impact resistance: The improved clutch push rod assembly provided by the present invention can withstand up to 8 million impacts, which is mainly due to the compressibility of the rubber tube and the rubber ball sleeve and fitting ring. The elastic properties of rubber can effectively absorb and disperse impact energy and protect the push rod assembly from damage.

[0012] 2. Flexible deflection capability: The slots designed on the engaging ring allow the lower ball of the push rod to achieve a small angle deflection inside the engaging ring. This design allows the push rod assembly to maintain a stable working state when subjected to non-axial forces, improving the adaptability and durability of the clutch.

[0013] 3. Stable connection structure: The clamping connection between the upper ball and the ball sleeve between the rubber tube and the push rod, as well as the fixed connection between the connecting tube and the limit sleeve, together constitute a stable and reliable connection structure. This design ensures the stability and reliability of the push rod assembly in long-term use.

[0014] 4. Optimized service life: Due to the use of wear-resistant and impact-resistant rubber materials and optimized structural design, the service life of the push rod assembly has been significantly improved. Even in harsh working environments, it can maintain long-term stable operation.

[0015] 5. Easy to maintain and replace: The modular design of the push rod assembly makes the connection between the various components simple and easy to disassemble. When a component fails or wears out, it can be easily replaced or repaired, reducing maintenance costs and downtime. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example:

[0019] like Figure 1-3 As shown, an embodiment of the present invention provides an improved clutch push rod assembly, including a rubber tube 1 and a push rod 3, the upper end of the rubber tube 1 is connected to a ball sleeve 2, the top end of the push rod 3 is clamped into the interior of the rubber tube 1, the top end of the push rod 3 is fixedly connected to an upper sphere 7, the upper sphere 7 is movably clamped in the interior of the ball sleeve 2, the outer surface of the upper sphere 7 is fitted with the inner wall of the ball sleeve 2, a connecting tube 4 is arranged below the rubber tube 1, the center axis of the rubber tube 1 and the connecting tube 4 are located in the same straight line, a connecting piece 6 is arranged below the connecting tube 4, the upper section of the connecting piece 6 is fixedly connected to a limiting sleeve 5, the lower end of the connecting tube 4 is clamped in the interior of the limiting sleeve 5, the connecting tube 4 is fixedly connected to the limiting sleeve 5, the connecting tube 4 is fixedly connected to the limiting sleeve 5, the interior of the connecting tube 4 is fixedly connected to a fitting ring 9, the lower end of the push rod 3 is fixedly connected to a lower sphere 8, the lower sphere 8 is movably clamped in the interior of the fitting ring 9.

[0020] The slotted design not only enhances the connection strength between the fitting ring 9 and the rubber tube 1 and the connecting tube 4, but also allows the lower ball 8 of the push rod 3 to achieve a small angle of free deflection in the fitting ring 9. This design improves the stability and adaptability of the push rod assembly when subjected to non-axial forces, ensuring the normal operation of the clutch under various working conditions.

[0021] The compressible rubber tube 1 can absorb and disperse the thrust from the clutch actuator, effectively reducing the direct impact on the clutch. This design not only prolongs the service life of the clutch, but also improves the overall impact resistance of the push rod assembly.

[0022] The larger contact area between the upper sphere 7 and the ball sleeve 2 increases the connection stability between the push rod 3 and the rubber tube 1. At the same time, the smaller contact area of ​​the lower sphere 8 in the fitting ring 9 allows it to achieve a small angle deflection, thereby improving the flexibility of the push rod assembly. This size design ensures both the stability of the connection and the flexibility.

[0023] The ball sleeve 2 and the fitting ring 9 are both made of rubber, which has good elasticity and wear resistance and can withstand the thrust of the clutch for a long time without being easily damaged. In addition, the rubber material can also absorb and disperse the impact force, further improving the impact resistance of the push rod assembly. This material selection ensures the stability and durability of the push rod assembly in harsh working environments.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
