Description

Automobile double joined v-belt

Technical field:

The utility model relates to automobile double joined v-belt more particularly to car duplex V-belts.

Background technique:

At present due to commonly used on coach driving system duplex V-belt replace multiple single V bands with prevent violent vibration and Two or more V bands are bound up by additional mutation load using high-strength canvas, and this high-strength canvas enhances belt Stability to avoid belt turning or run out of belt wheel, to solve the problems, such as such as high load capacity in some applications, frequently The system etc. of high torque starting.

But car is different with automotive V-belt or common industrial joined v-belt with duplex V-belt at present, does not have corresponding Professional standard, it is higher in view of occupation rate of the automobile double joined v-belt at home in automobile market of Gates Co., Ltd's production, therefore city Standard next life on field frequently with Gates Co., Ltd steams vehicle duplex V-belt.

At present Gates Co., Ltd production 2/AV15 model duplex V-belt, band with a thickness of 12mm to 14mm, width is 34.6mm to 35.3mm, but the duplex V-belt abrasion of existing market feedback 2/AV15 is very fast, loses too early in use The problems such as effect, causes the increase of cost, while the top layer connection canvas being connected arches upward, easily causes the vibration of transmission system, because This urgent need provides the new duplex V-belt of one kind come the technical issues of solving premature failure and driveline vibrations.

Summary of the invention:

To solve the above problems, the utility model provides a kind of new automobile double joined v-belt, including two V-arrangement teeth 5 of connection Top layer connect canvas 1, cotton rope 2 and body rubber 3, which is 34 ° to 40 ° with a thickness of 12mm to 13.5mm, profile angle Ab, Top width Wb is 35.4mm to 36.2mm.

Preferably, the top width Wb of automobile double joined v-belt is 35.8mm.

Preferably, the thickness H of automobile double joined v-belt is 13mm.

The profile angle Ab of automobile double joined v-belt is 38 °

The band further includes the waveform tooth 4 on V-arrangement tooth 5.

The outer surface of the V-arrangement tooth 5 of band covers cloth 6 with teeth.

It can effectively improve using the automobile double joined v-belt of the utility model and cross quick-wearing and top layer with what unbalance stress generated Connection canvas among arch upward caused by driveline vibrations problem, effectively raise automobile double joined v-belt service life and Improve the comfort property of car.

Detailed description of the invention

Fig. 1 is the utility model automobile double joined v-belt structural schematic diagram；

Fig. 2 is the partial cutaway schematic of the utility model automobile double joined v-belt.

Specific embodiment:

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail, with Lower embodiment is not limitations of the present invention for illustrating the utility model.

As shown in Figure 1 and Figure 2, automobile double joined v-belt includes the top layer connection canvas 1 for connecting two V-arrangement teeth 5, cotton rope 2 and Body rubber 3, since duplex V-belt intensity is larger, lower part generally on each V-arrangement tooth 5 shown in dotted line (see Fig. 2), setting Have along the concave-convex alternately arranged waveform tooth 4 in strip length direction, as shown in Figure 1.For the bearing capacity for improving band, part-structure is in V Cloth 6 with teeth is covered on the outer surface of shape tooth.To increase cohesive force, generally connects in top layer and be provided between canvas and body rubber Adhesive layer (not shown), cotton rope 2 are located in adhesive layer, prevent cotton rope 2 from connecting the removing of canvas 1 with body rubber 3 and top layer, make Joined v-belt failure in pairs.

The design feature of the automobile double joined v-belt of the utility model is that the overall thickness H of duplex V-belt arrives for 12mm 13.5mm or so, preferably 13mm；The profile angle Ab of band is 34 °~40 °；To make automobile double joined v-belt that there is centainly soft Toughness is readily bent to be cooperated with belt wheel, below such as Fig. 1 dotted line of band body lower part, i.e., is provided with along strip length direction on V-arrangement tooth 5 Bumps are alternately arranged the waveform tooth 4 to be formed；The top width Wb of band is 35.4mm to 36.2mm, preferably 35.8mm.

Top width of the automobile double joined v-belt of the utility model due to increasing duplex V-belt, makes the rubbing surface phase with outside Belt wheel is moved up, prevents joined v-belt from sinking relative to belt wheel, unbalance stress causes belt wear uneven, in turn results in office Portion's serious wear makes band premature failure；Since concentrated wear is serious, band unbalance stress causes the intermediate connection canvas of band to arch upward.By It is relatively broadening in the V-arrangement tooth of the width for increasing band, band, it is moved up with the V-arrangement tooth of belt wheel cooperation relative to belt wheel, is being driven band Each position uniform force is kept in the process, and anti-stop-band intermediate arches play and cause the vibration of transmission system, and improve band uses the longevity The comfort property of life and transmission system.

Verified statistical data is as follows:

Bandwidth Wb	Band crash rate	Vibration
			35	6%	6%
35.5	1%	1%
			35.8	0.3%	0.5%

As seen from the above table, in the case where the thickness of band and toothed region change, when the width of automobile double joined v-belt is increased by 35 The crash rate of band drops to 1% by 6% when adding to 35.5, and the vibration of band is also reduced to 1% by 6%；When the width of band is changed to When 35.8, the crash rate of band drops to 0.3%, and vibration is reduced to 0.5%.The automobile double for being 34.6mm to 35.3mm relative to width Joined v-belt, crash rate has very big improvement, and vibration is significantly reduced.
