Abstract
The utility model provides a ribbed belt for an automobile, which comprises a rubber body with a tooth profile, a cloth cover is arranged on the back surface of the rubber body opposite to the tooth profile, at least one layer of glass fiber cloth is arranged in the rubber body, and the glass fiber cloth is located behind the tooth profile. The glass fiber cloth is generally used for enhancing the product intensity; however, when the glass fiber cloth is applied to the ribbed belt, the oil and heat resisting performances of the ribbed belt are greatly improved unexpectedly; in addition, the tensile strength of the ribbed belt is greatly improved, thereby further prolonging the service life of the ribbed belt of the automobile.
Description
(1) technical field
The utility model relates to a kind of automobile poly Vbelt.
(2) background technique
Automobile multi-wedge belt is the driving belt that a kind of working surface has dentation structure, with reference to Fig. 1, it comprises the rubber body 2 with profile of tooth 1, and the back side of the rubber body relative with profile of tooth 1 is provided with cloth cover 3, be provided with one deck skeleton line rope 4 at least in the rubber body 2, skeleton cotton rope 4 is positioned at the rear of profile of tooth 1.Skeleton cotton rope 4 general employing nylon or aramid fibre, polyester line, canvas etc., the skeleton cotton rope makes improve greatly the working life of automobile multi-wedge belt, but its oil resistance, heat resistance and pull resistance still remain to be improved.
(3) summary of the invention
In order to overcome existing automobile multi-wedge belt oil resistance, heat resistance and pull resistance defective not enough, the utility model provides a kind of oil resistance and heat resistance better to improve the automobile multi-wedge belt in working life.
The technical scheme in the invention for solving the technical problem is: a kind of automobile poly Vbelt, comprise rubber body with profile of tooth, the back side of the rubber body relative with described profile of tooth is provided with the cloth cover, be provided with one deck glass fiber cloth at least in the described rubber body, described glass fiber cloth is positioned at the rear of described profile of tooth.
Further, also be provided with one deck skeleton line rope at least in the described rubber body, with the working life of further enhancing automobile multi-wedge belt.Described skeleton cotton rope is positioned at the rear of described profile of tooth.
Further, described glass fiber cloth is positioned at the place ahead of described skeleton cotton rope.
The beneficial effects of the utility model are: glass fiber cloth generally is used for strengthening the intensity of goods, but glass fiber cloth is applied in the utility model, but be surprised to find that the oil resistance and the heat resistance that have strengthened automobile multi-wedge belt widely, and can improve the pull resistance of poly Vbelt greatly, thereby the working life of further having improved automobile multi-wedge belt.
(4) description of drawings
Fig. 1 is the structural representation of existing automobile multi-wedge belt.
Fig. 2 is the structural representation of automobile multi-wedge belt of the present utility model.

Embodiment four
A kind of automobile poly Vbelt comprises the rubber body with profile of tooth, and the back side of the rubber body relative with described profile of tooth is provided with the cloth cover, is provided with layer of glass cloth in the described rubber, and described glass fiber cloth is positioned at the rear of described profile of tooth.The skeleton cotton rope adopts the polyester line.
Comparative Examples
With reference to Fig. 1, a kind of automobile poly Vbelt, it comprises the rubber body 2 with profile of tooth 1, and the back side of the rubber body relative with profile of tooth 1 is provided with cloth cover 3, is provided with one deck skeleton line rope 4 at least in the rubber body 2, and skeleton cotton rope 4 is positioned at the rear of profile of tooth 1.The skeleton cotton rope adopts the polyester line.
The poly Vbelt of embodiment one, embodiment two, embodiment three, embodiment four and Comparative Examples is stretched in carries out the fatigability test on the same turbine, the temperature of test is 107 ℃, and rotating speed is 3300r/min, and tension force is 680N, and test result is as follows:
One: 116 hour poly Vbelt of embodiment produces 1 cracking, produces 3 crackings in 130 hours, 5 crackings of generation in 140 hours, 9 crackings of generation in 152 hours; Pitch length is 964.70mm before the test, and test back pitch length is 964.44mm.
Two: 75 hours poly Vbelts of embodiment produce 1 cracking, 2 crackings of generation in 80 hours, 15 crackings of generation in 90 hours; Pitch length is 963.80mm before the test, and test back pitch length is 963.30mm.
Three: 72 hours poly Vbelts of embodiment produce 1 cracking, 3 crackings of generation in 94 hours, 10 crackings of generation in 119 hours; Pitch length is 963.80mm before the test, and test back pitch length is 963.60mm.
Four: 68 hours poly Vbelts of embodiment produce 1 cracking, 3 crackings of generation in 73 hours, 13 crackings of generation in 80 hours; Pitch length is 963.80mm before the test, and test back pitch length is 963.58mm.
