Abstract

The invention discloses a nylon cord elastic V belt, an engine front end wheel train and a test method. The nylon cord elastic V belt comprises a V belt body, the V belt body comprises a canvas outer layer, a buffer rubber layer and a main body rubber layer from outside to inside, the buffer rubber layer is arranged between the canvas outer layer and the main body rubber layer, and the buffer rubber layer is provided with a plurality of elastic cords along the length direction of the buffer rubber layer. The nylon cord elastic V belt has the advantages of simple structure, small tension attenuation and the like.

Description

technical field [0001] The invention relates to the technical field of engine accessory assembly, in particular to a nylon cord elastic V-belt, an engine front wheel train and a test method. Background technique [0002] At present, the V-belts used at home and abroad, the middle part of the cord is made of polyester cord, the belt has poor elasticity, and the tension of the belt is seriously attenuated during use. In the front-end wheel system of an automobile engine, if the belt transmission structure of the fatigue equipment is non-automatically tensioned, and the tension of the new belt is initially installed at 490N, after the fatigue equipment runs for 20 minutes, the belt tension will decay to 250N or even lower. At this time, manual tensioning is required. Retighten the belt to make the tension reach more than 400N. After running for a long time, the length of the belt will continue to elongate, and the tension of the belt will continue to decrease. It is necessary ...
