Problems solved by technology

[0005] The present invention mainly aims at the above-mentioned existing technical problems and makes further improvements. It provides a transmission belt with a fabric on the back and the fabric is sewn with sutures, and the surface of the fabric has a raised pattern structure rubber. The sutures of the transmission belt are patterned The structural rubber is covered without leakage, the appearance of the transmission belt is good, and it can further reduce or solve the problem of the wear of the suture and the periodic noise caused by the contact between the pulley and the suture during the operation of the transmission belt

Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] The transmission belt of the present invention is a V-ribbed belt as an example, but is not limited thereto, and may also be a synchronous belt or a V-belt.

[0026] like Figure 4 The V-ribbed belt shown includes a bottom rubber layer 1, an adhesive rubber layer 5, a tensile cord 2 embedded in the adhesive rubber layer, and a back fabric layer 4 bonded to the back of the adhesive rubber layer 5, as in image 3 As shown, the fabric layer has a butt joint c sewn with stitches d, and the bottom rubber layer 1 has at least one rib extending along the length of the drive belt.

[0027] The bottom rubber layer and the rubber adhering to the rubber layer can be made of the same rubber or different rubbers. It is made by mixing several kinds of rubbers, and it can also include other kinds of rubbers. Fibers to improve strength or water absor...

Abstract

The inventions provides a driving belt. A fabric layer covers on the back of the driving belt; the fabric layer is provided with a butt joint sewn by threads; the outer surface of the fabric layer is projecting pattern structure rubber, the threads are covered in the projecting pattern structure rubber. Compared with the traditional driving belt with fabric on the back, the driving belt with the structure has better appearance, and the noise is relieved further.

Description

Technical field: [0001] The present invention relates to power transmission belts, especially power transmission belts having a fabric back. Background technique: [0002] With the continuous improvement of human living standards, the automobile market is also developing and expanding with each passing day, and the requirements for stability and comfort are getting higher and higher. Therefore, the drive belt of the automobile drive system is required to maintain stable operation and low noise in the drive system. Higher and higher. [0003] Early power transmission belts such as figure 1 As shown, the fabric 11, rubber 12, tensile cord 13, and rubber 14 are wound on the mold 15 to form a rubber sleeve as required, and then the rubber sleeve is vulcanized. The vulcanized rubber sleeve is cut into a predetermined width according to various sizes. Transmission belt. The fabric 11 is wound on the cylindrical mold 15 and forms a joint on the outer surface of the mold approxim...
