Description

Technical Field

[0001] This utility model relates to the field of telescopic clutch manufacturing technology, specifically a quick-clamp spring for telescopic clutches that is easy to assemble and can achieve axial and radial clamping. Background Technology

[0002] Telescopic clutches engage and disengage power transmission through axial extension and retraction. Commercially available telescopic clutches require the simultaneous assembly of both clutch discs and limit springs into external limiting components during installation. This assembly process involves compressing the limit springs, making positioning difficult and resulting in low installation efficiency. Summary of the Invention

[0003] This utility model addresses the shortcomings and deficiencies of existing technologies by proposing a quick-clamping spring for telescopic clutches that has a reasonable structure, is easy to assemble, and can achieve both axial and radial clamping.

[0004] This utility model achieves its purpose through the following measures: A quick-release clamping spring for a telescopic clutch is characterized in that it has a fixed end wound in a U-shape and a first clamping part and a second clamping part respectively connected to the fixed end. The first clamping part and the second clamping part are both arranged vertically and are wound in a frame shape with notches.

[0005] The fixed end, the first clamping part and the second clamping part of this utility model are an integral structure. The first clamping part and the second clamping part are arranged on both sides of the fixed end to achieve axial clamping of the device. The notched frame structure of the first clamping part and the second clamping part are respectively used to radially clamp the two ends of the device.

[0006] The first clamping part of this utility model radially clamps the input end of the telescopic clutch. Since the boss of this part is small, the first clamping part adopts a rectangular frame shape with an opening on one side, and the clamping is completed by two opposite sides. The opening faces the fixed end to press the telescopic clutch onto the plane and prevent it from popping up during operation.

[0007] The second clamping part of this utility model radially clamps the output end of the telescopic clutch. It adopts a rectangular frame with an opening at one corner. The four sides respectively press the protruding structural components of the telescopic clutch radially from four directions, and the opening is located at the bottom end.

[0008] In order to improve the axial clamping stability, the closed end of the fixed end of this utility model is provided with a bent part to shorten the width of the U-shaped straight section and increase the clamping force. Furthermore, the fixed end can be set as a straight fixed end in the horizontal direction, or wound into an arc shape to adapt to the external limiting structure, so as to meet safety requirements.

[0009] In use, this utility model can ensure convenient installation while compressing the two clutch discs and applying frictional torque to one end, i.e., it can be installed radially from the side. This solution improves the difficulty of assembling four parts—two clutch discs, springs, and an external limiting structure—in a telescopic clutch, and also supports the assembly method of first installing the two clutch discs and the external limiting structure and then installing the spring. It also supports the assembly method of first assembling the spring and the two clutch discs to form a clutch component and then pressing the clutch component into the external limiting structure, which greatly simplifies and optimizes the installation method.

[0010] Compared with the prior art, this utility model has significant advantages such as reasonable structure and simple assembly. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] As attached Figure 1 , 2 As shown in Figure 3, this example proposes a quick-release clamping spring for a telescopic clutch, which has a fixed end 1 wound in a U-shape and a first clamping part 2 and a second clamping part 3 respectively connected to the fixed end 1. The first clamping part 2 is arranged vertically, and the second clamping part 3 is inclined toward the first clamping part 2 to clamp both ends of the clutch (as shown in the attached figure). Figure 3 As shown), both the first clamping part 2 and the second clamping part 3 are wound into a frame shape with notches; the fixed end 1, the first clamping part 2 and the second clamping part 3 are an integral structure. The first clamping part 2 and the second clamping part 3 are arranged on both sides of the fixed end 1 to achieve axial clamping of the device. The notched frame structure of the first clamping part 2 and the second clamping part 3 are used to radially clamp the two ends of the device respectively; the first clamping part 2 radially clamps the input end of the telescopic clutch. Since the boss size of this part is small, the first clamping part 2 adopts a rectangular frame shape with an opening on one side, and the clamping is completed by two opposite sides. The opening faces the flat end to press the telescopic clutch onto the plane and prevent it from popping up during operation. As attached Figure 2As shown, in this example, the second clamping part 3 radially clamps the output end of the telescopic clutch. It adopts a rectangular frame shape with an opening at one corner. The four sides respectively press the output end protruding part of the telescopic clutch radially from four directions, and the opening is located at the bottom end. At this time, the top corner at the top provides the clamping force F. 压紧 The clamping force F is provided from the top of the second clamping part 3 on both sides towards the radial center. 夹紧 ; To improve axial clamping stability, the closed end of the fixed end 1 is provided with a bent portion 4 to shorten the width of the U-shaped straight section and increase the clamping force. Furthermore, the fixed end 1 can be set as a straight fixed end in the horizontal direction, or wound into an arc shape that adapts to the external limiting structure to meet safety requirements.

[0017] In use, this utility model can ensure convenient installation while compressing the two clutch discs and applying frictional torque to one end, i.e., it can be installed radially from the side. This solution improves the difficulty of assembling four parts—two clutch discs, springs, and an external limiting structure—in a telescopic clutch, and also supports the assembly method of first installing the two clutch discs and the external limiting structure and then installing the spring. It also supports the assembly method of first assembling the spring and the two clutch discs to form a clutch component and then pressing the clutch component into the external limiting structure, which greatly simplifies and optimizes the installation method.

[0018] Compared with the prior art, this utility model has significant advantages such as reasonable structure and simple assembly.
