Description

Technical Field

[0001] This utility model relates to the field of automotive arc spring technology, specifically an arc spring for automotive hydraulic torque converters. Background Technology

[0002] An automotive hydraulic torque converter is a non-rigid torque converter, mainly used in automatic transmission vehicles to connect the engine and the transmission, realize the transmission of speed and torque, and make the connection between the two non-rigid, which facilitates automatic gear shifting of the automatic transmission.

[0003] Therefore, the arc spring used in the automotive hydraulic torque converter will be used as an elastic element to connect the engine and the transmission, and its main function is to provide cushioning and vibration damping.

[0004] However, the existing curved springs still have the following defects: Since both ends of the current curved springs are connected to the torque converter housing and engine crankshaft by ordinary snap-fit, the ordinary snap-fit ​​connection is very easy to cause the springs to loosen and become unstable when transmitting power, which reduces the stability of the curved springs.

[0005] Meanwhile, curved springs are typically used with a single spring as the main component. Therefore, when bent and connected for fixation, the relatively simple structure causes continuous vibration during the bending process, reducing its damping strength and thus its overall durability. Utility Model Content

[0006] To address the above problems, this utility model provides an arc-shaped spring for automotive hydraulic torque converters.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an arc-shaped spring for an automotive hydraulic torque converter, the structure of which includes: a spring body, a connecting end, and a combined structure. The left and right sides of the spring body are fixedly connected to the combined structure through the connecting end, and the combined structure is bent to form an arc-shaped spring.

[0008] Furthermore, the combined structure includes a first positioning block, a locking block, a bolt head, a rubber column, a second positioning block, a protrusion, and a novel locking structure. The first positioning block is fixedly connected to the locking block and, together with the bolt head, completes the threaded connection with the rubber column. The other end of the rubber column is embedded in the second positioning block. The second positioning block and the protrusion are perpendicular to each other. The surface of the protrusion is also provided with a novel locking structure to complete the fixed connection with the automobile torque converter housing and the engine crankshaft.

[0009] Furthermore, based on the first and second positioning blocks of the combined structure, the rubber column of the second positioning block passes through the center of the spring body through the bolt head and is then threadedly connected to the center of the locking block of the first positioning block. The protrusion is then embedded in the torque converter housing and the engine crankshaft, and then fixed using a new locking structure.

[0010] Furthermore, the connecting ends on the left and right sides of the spring body are parallel to each other and their center points coincide, and the combined structure is arranged on the left and right sides of the spring body.

[0011] Furthermore, the first positioning block and the second positioning block are symmetrical to each other, and the locking block has an internal thread in the center to complete the threaded connection with the bolt head of the rubber column. The protrusion is provided in the center of the first positioning block and the second positioning block and carries three sets of new locking structures.

[0012] Furthermore, the novel locking structure also includes a restraining block with an adsorption plate connected to its upper end. The adsorption plate covers the lower part of the balance plate, and a threaded groove is opened in the center of the balance plate to allow the screw to be vertically embedded and locked. A rotating module is welded to the top of the screw.

[0013] Furthermore, the restraining block is perpendicular to the lower end of the balance plate via the center of the adsorption plate, and the threaded groove of the balance plate passes through the center of the restraining block and the adsorption plate. A solid block is connected to the center of the rotating module at the upper end of the screw.

[0014] Furthermore, the connecting end is also provided with a parallel block, which is welded to the center of the welding module. A spring connecting block is connected to the top of the welding module, and the vertical block is positioned by the spring connecting block. A locking head is connected in the vertical block so that one end of the rubber column can be embedded in the threaded connection.

[0015] Furthermore, the welding module of the parallel block is rectangular in shape and its length is shorter than that of the top spring connecting block. The spring connecting block is perpendicular to the top vertical block, and there is a gap between the inner wall of the vertical block and the edge of the locking head so that one end of the rubber column can be embedded. Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model further improves upon the combination structure on the left and right sides of the spring body by utilizing the protrusions mounted on the center of the first and second positioning blocks and a new locking structure. The protrusions can be pre-embedded in the torque converter housing and the engine crankshaft. Then, the rotating module of the new locking structure manually drives the screw through the threaded groove area of ​​the balance plate, thus enabling rapid locking. At the same time, the adsorption plate at the bottom of the balance plate will adsorb onto the surface area of ​​the torque converter housing and the engine crankshaft, thus replacing the original simple snap-fit ​​connection process. This further improves the firmness of the connection between the spring body, which is bent into an arc spring, and the torque converter housing and the engine crankshaft, avoiding the instability caused by simple snap-fit ​​during power transmission.

[0018] 2. This utility model further improves upon the combination structure on the left and right sides of the spring body by using the locking block of the first positioning block to allow the rubber column of the second positioning block to penetrate the center of the spring body. This allows the rubber column to work with the spring body to perform shock absorption based on its own rubber bending and elasticity, thereby improving the strength of the spring body and avoiding the reduction in its stability of use caused by the original single spring.

[0019] 3. By further improving the connecting end of the side of the combined structure, this utility model can effectively improve the accuracy of welding the spring connecting block to the side of the combined structure through the welding module by the position restraint of the parallel block, preventing tilting. Furthermore, the vertical block mounted at the top center can complete the threaded connection with one end of the rubber column and the bottom center of the locking block by the internally set locking head. Therefore, it can ensure that the center of the rubber column can be limited, thereby ensuring that the rubber column can swing with the swing of the spring body when used for auxiliary purposes, preventing the center point deviation from reducing the overall stability of the component.

[0030] like Figures 1-4 As shown, this utility model provides an arc-shaped spring for automotive hydraulic torque converters.

[0031] Its structure includes a spring body 1, a connecting end 2, and a combination structure 3. The left and right sides of the spring body 1 are fixedly connected to the combination structure 3 through the connecting end 2 and are bent into an arc-shaped spring through the combination structure 3.

[0032] The combined structure 3 includes a first positioning block 31, a locking block 32, a bolt head 33, a rubber column 34, a second positioning block 35, a protrusion 36, and a novel locking structure 37. The first positioning block 31 is fixedly connected to the locking block 32 and, together with the bolt head 33, completes the threaded connection with the rubber column 34. The other end of the rubber column 34 is embedded in the second positioning block 35. The second positioning block 35 and the protrusion 36 are perpendicular to each other. The surface of the protrusion 36 is also provided with a novel locking structure 37 to complete the fixed connection with the automobile torque converter housing and the engine crankshaft.

[0033] Based on the first positioning block 31 and the second positioning block 32 of the combined structure 3, the rubber column 34 of the second positioning block 35 passes through the center of the spring body 1 through the bolt head 33 and is then threadedly connected to the center of the locking block 32 of the first positioning block 31. The protrusion 36 is then embedded in the torque converter housing and the engine crankshaft, and then fixed by the new locking structure 37.

[0034] The connecting ends 2 on the left and right sides of the spring body 1 are parallel to each other and their center points coincide. The combined structure 3 is arranged on the left and right sides of the spring body 1.

[0035] The first positioning block 31 and the second positioning block 35 are symmetrical to each other, and the locking block 32 has an internal thread in the center to complete the threaded connection with the bolt head 33 of the rubber column 34. The protrusion 36 is provided in the center of the first positioning block 31 and the second positioning block 35 and carries three sets of new locking structures 37.

[0036] The novel locking structure 37 is further provided with a restraining block 371. An adsorption plate 372 is connected to the upper end of the restraining block 371. The adsorption plate 372 covers the lower end of the balance plate 373. A threaded groove 374 is opened in the center of the balance plate 373 to allow the screw 375 to be vertically embedded and locked. A rotating module 376 is welded to the top of the screw 375.

[0037] The restraining block 371 is perpendicular to the lower end of the balancing plate 373 through the center of the adsorption plate 372. The threaded groove 374 of the balancing plate 373 passes through the center of the restraining block 371 and the adsorption plate 372. A solid block is connected to the center of the rotating module 376 at the upper end of the screw 375.

[0038] The connecting end 2 is also provided with a parallel block 21, which is welded to the center of the welding module 22. A spring connecting block 23 is connected to the top of the welding module 22. The vertical block 24 is positioned by the spring connecting block 23. A locking head 25 is connected in the vertical block 24 so that one end of the rubber column 34 is embedded in the threaded connection.

[0039] The welding module 22 of the parallel block 21 is rectangular and its length is shorter than that of the top spring connecting block 23. The spring connecting block 23 is perpendicular to the top vertical block 24, and there is a gap between the inner wall of the vertical block 24 and the edge of the locking head 25 so that one end of the rubber post 34 can be embedded.

[0040] The working principle of this utility model is explained below: The arc-shaped spring for the automotive hydraulic torque converter can be positioned by the combination structure 3 at both ends and the connecting end 2. Then, according to the position of the torque converter housing and the engine crankshaft, the spring body 1 is bent and fixed to complete the connection between the torque converter housing and the engine crankshaft. Then, according to the setting of the arc-shaped spring, it can effectively provide a buffering and shock absorption effect for the torque converter housing and the engine crankshaft. After the first positioning block 31 of the combination structure 3 determines the position of the locking block 32, the rubber column of the second positioning block 35 can be... 34, carrying bolt head 33, is embedded into locking block 32 for connection, so that rubber post 34 penetrates the center of spring body 1. This allows the spring body 1 to increase its strength based on its rubber cushioning properties. Then, combined with the protrusions 36 on the sides of positioning block 31 and positioning block 35, it can be embedded in the connection area between torque converter housing and engine crankshaft. Simultaneously, the balance plate 373 of the new locking structure 37 can be vertically embedded into protrusion 36 using adsorption plate 372 and restraint block 371, thus entering the connection area between torque converter housing and engine crankshaft. Internally, a positional constraint is formed, and then the threaded groove 374 on the balance plate 373 is opened in a vertical orientation, allowing the screw 375 to be manually rotated and locked in in conjunction with the rotating module 376. This replaces the original simple snap-fit ​​positioning, preventing gradual loosening under continuous stress and improving the connection strength with the torque converter housing and engine crankshaft connection area, preventing detachment. Finally, the connecting end 2 on the side of the combined structure 3 can use the parallel block 21 to position the welding module 22 at the center of the first positioning block 31 and the second positioning block 35. Then, the spring connecting block 23 is fixed into the combined structure 3 by welding, which can improve the connection stability between the spring body 1 and the combined structure 3. Subsequently, the vertical block 24 on the surface of the spring connecting block 23 can be spliced ​​with the locking block 32 and one end of the rubber column 34 by the built-in locking head 25. According to the position restraint, it can improve the center overlap accuracy of the rubber column 34 and the locking block 32, ensuring that the center of the spring body 1 can be penetrated in a straight line, which further improves the stability of the overall arc spring connection in the torque converter housing and engine crankshaft.

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.
