Description

Technical Field

[0001] This utility model relates to the field of continuously variable transmission (CVT) technology, specifically to a load-bearing ring structure used in the transmission belt of a CVT. Background Technology

[0002] Continuously variable transmissions (CVTs) are divided into variable slope CVTs and continuously variable transmissions (CVTs). CVTs eliminate the complex and cumbersome gear combination transmission and only use two sets of pulleys for transmission. CVTs achieve speed changes by altering the contact radius between the drive and driven pulleys and the transmission belt. Because CVTs can continuously change the transmission ratio, they achieve optimal matching between the transmission system and engine operating conditions, improving fuel economy and power, driver convenience, and passenger comfort. Therefore, they are ideal automotive transmission devices. Continuously variable transmissions (CVTs) typically utilize changes in the diameter of a steel belt on the pulleys for continuously variable speeds. This steel belt, also called a drive belt, is composed of multiple stacked steel sheets. Currently, when separating and fixing the steel sheets, the current drive belts require individual removal and placement of the sheets. This can easily cause the sheets to become scattered, affecting disassembly and assembly. During use, if one or more steel sheets are damaged or broken, it affects the gaps between the stacked sheets, causing the sheets in areas with larger gaps to tilt and misalign. This can lead to incalculable damage to the drive belt before it is stopped for maintenance, significantly impacting its lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a load-bearing ring structure for use in the transmission belt of a continuously variable transmission (CVT), solving the problems of inconvenient disassembly and easy damage of the load-bearing ring structure currently used in CVT transmissions.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A load-bearing ring structure used in the transmission belt of a continuously variable transmission (CVT) includes a device body. The device body includes two connecting belts and thrust blocks arranged in a circumferential array on the two connecting belts. Each thrust block has a through-hole. A connecting rope is provided on the device body. One end of the connecting rope is fixedly connected to an abutment plate, which abuts against the thrust block. The other end of the connecting rope is rotatably connected to a threaded rod. One end of the connecting rope located on the threaded rod passes through the through-hole on each thrust block in sequence, and the threaded rod on the connecting rope is threadedly connected to a threaded groove on one side of the abutment plate.

[0008] Furthermore, a sleeve and a spring are slidably connected to the corresponding position of each thrust block on the connecting rope. The sleeve is positioned between two adjacent springs and is plugged into the through port.

[0009] Furthermore, the thrust block has mounting slots at both ends of the through-hole, and the contact plate is adapted to the mounting slots.

[0010] Furthermore, the sleeve rod includes a thick rod and a thin rod. One end of the thick rod and the thin rod are fixedly connected to an adapter plate that is adapted to the mounting groove. The other end of the thin rod is inserted into a thin groove opened at the other end of the thick rod. The thick rod is inserted into the through port.

[0011] Furthermore, grooves are provided on both sides of the thrust block, and the thrust block is installed on the connecting belt through the grooves.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1 to 7 As shown in the figure, a load-bearing ring structure used in the transmission belt of a continuously variable transmission (CVT) according to an embodiment of the present invention includes a device body 1. The device body 1 includes two connecting belts 2 and thrust blocks 3 distributed in a circumferential array on the two connecting belts 2. The thrust blocks 3 are provided with through-holes 8. A connecting rope 5 is provided on the device body 1. One end of the connecting rope 5 is fixedly connected to an abutment plate 6. The abutment plate 6 abuts against the thrust blocks 3. The other end of the connecting rope 5 is rotatably connected to a threaded rod 7. The end of the connecting rope 5 located at the threaded rod 7 passes through the through-holes 8 on each thrust block 3 in sequence, and the threaded rod 7 on the connecting rope 5 is threadedly connected to a threaded groove opened on one side of the abutment plate 6.

[0027] The connecting rope 5 is a steel wire rope, the thrust block 3 is a steel sheet or metal sheet, and the connecting belt 2 is a metal bearing belt; the connecting rope 5 is connected in series with each thrust block 3 at the end of the threaded rod 7 so that each thrust block 3 is stacked on top of each other, and then the threaded rod 7 is threadedly connected to the threaded groove on the contact plate 6.

[0028] If the outer diameter of the contact plate 6 is larger than the outer diameter of the opening 8, the contact plate 6 cannot pass through the opening 8. When the contact plate 6 and the threaded rod 7 are connected by threads, the connecting rope 5 with a larger bend in the area between the threaded rod 7 and the contact plate 6 can be used to widen the gap in that area. Fine tweezers or other tools are needed to hold the threaded rod 7. The outer side of the threaded rod 7 needs to have a circumferential array of notches to facilitate pushing and pulling the outer side of the threaded rod 7 so that the threaded rod 7 can rotate and be threaded into the threaded groove.

[0029] like Figure 3 As shown, in some embodiments, a sleeve rod 4 and a spring are slidably connected to the corresponding position of each thrust block 3 on the connecting rope 5. The sleeve rod 4 is disposed between two adjacent springs and is plugged into the through port 8.

[0030] The sleeve rod 4 is used to stabilize the thrust block 3. The spring force is used to push each thrust block 3 against each other to prevent the thrust block 3 from tilting or misaligning.

[0031] like Figure 5 and Figure 6 As shown, in some embodiments, the thrust block 3 is provided with mounting grooves 9 at both ends of the slot of the through port 8, and the contact plate 6 is adapted to the mounting grooves 9.

[0032] The mounting slot 9 is for the purpose of concealing the contact plate 6 and preventing the contact plate 6 from obstructing the two adjacent thrust blocks 3.

[0033] like Figure 7 As shown, in some embodiments, the sleeve rod 4 includes a thick rod 402 and a thin rod 401. One end of the thick rod 402 and the thin rod 401 are fixedly connected to an adapter plate that is adapted to the mounting groove 9. The other end of the thin rod 401 is inserted into the thin groove opened at the other end of the thick rod 402. The thick rod 402 is inserted into the through port 8.

[0034] The thick rod 402 and the thin rod 401 are connected by interlocking to facilitate the placement of the sleeve rod 4 into the through-hole 8.

[0035] like Figure 5 As shown, in some embodiments, grooves 10 are provided on both sides of the thrust block 3, and the thrust block 3 is installed on the connecting belt 2 through the grooves 10;

[0036] Groove 10 is used to install connecting strap 2.

[0037] like Figure 5 and Figure 6 As shown, in some embodiments, two circular blocks 11 are fixedly connected to one side of the thrust block 3, and a circular groove 12 adapted to the circular block 11 is provided at the corresponding position of the other side of the thrust block 3.

[0038] Both the circular block 11 and the circular groove 12 are located in the area where the thrust block 3 is located inside the connecting belt 2. When the device body 1 bends, the area where the thrust block 3 is located inside the connecting belt 2 will abut against the circular groove 12 on the adjacent thrust block 3 through the circular block 11, and cause the circular block 11 to roll and rotate on the inner wall of the circular groove 12.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
