Summary of tire rolling losses

To increase tire rolling loss of 3.5. Therefore, to reduce rolling loss, the use of tubeless tires is beneficial. 6 Scroll to reduce the losses and the current research trends in recent years. People to improve vehicle economy had a strong interest. Loss of vehicle due to tire rolling energy consumption - a result of the impact of major claims. Therefore, the loss of a vehicle tire rolling plays an important role in fuel consumption. The vehicle speed is 90 ~ llOkm / h range, a typical car is about the energy consumed by the total energy consumed by vehicles, 3 ~ 7 \Any reduction will no doubt be a large fuel savings effect. GM's recent research shows that the loss can be reduced to zero if the scroll,[link widoczny dla zalogowanych], then the fuel consumption can be reduced 12% ~ l9. Because the U.S. automobile fuel consumption is currently about The country's total gasoline consumption volume 25, through the tire rolling loss reduced to zero, then the U.S. can reduce fuel consumption of about 4 ��1��. energy consumption will be the smallest ideal tire with less or no lag with the loss of these materials. In order to obtain a smaller loss of value of the scroll, now,[link widoczny dla zalogowanych], the new tread rubber can be prepared by the following changes: �� macro and micro changes in the polymer end play; �� {�� change the composition of polymer chain end of the change of polymer resistance. As the existing material has fools flexibility. Therefore, in use between cord and rubber strain generated should be kept to a minimum value on. the tires under the control of the user can simply change the only parameter is the charge gas pressure, the parameter will be affected to some extent, the loss of existing rolling tire. And with the tire structure or independent of the materials they use. However, the tire pressure is too high will reduce the ride comfort and impact resistance, and because from the rim in the end of attacks coming from the larger disk, but also exacerbate the damage vehicle components. to reduce the tire weight is also an effective way to reduce the rolling losses. make the tire weight is the easiest way to reduce the volume of tread rubber. but it will lead to reducing tire life. In order to maintain the total life of the tire change, a new preparation with a compound of high wear resistance, it is a means of development of new technologies. To reduce the rolling loss, a two-tier tread (that is,[link widoczny dla zalogowanych], tread rubber and base) , it is a means of design changes. Its approach is to have high wear resistance and good wet skid tread rubber used for the outer layer. and low hysteresis loss as tread rubber lining. On this kinds of structures, has 30 patents in Japan,[link widoczny dla zalogowanych], made an application. Yoshimura, etc. \gel. by tin atoms to the cavity 4 SBR chain link can be made four times the molecular weight of the original star polymer. With this technique, a small hysteresis loss can be obtained, the wet slip resistance, good roads, tensile strength and wear resistance polymer. almost 1O years, the tire industry has reduced tire rolling loss of more than 3O. This is due to the use of the radial tire and rubber materials such as low hysteresis loss results. can be expected in the next tire rolling resistance coefficient will continue to decrease, and the fork does not reduce its other properties. This may be achieved by reducing the weight of the tire. Figure 16 shows the tire rolling past l5 years,[link widoczny dla zalogowanych], reduce the losses of the situation. l �� 0806 �� Meng �� 1_ 520} u2'l�� Lu lost �� sneeze 'yam H, \to reduce the loss of the icon of the rolling tire other performance factors and the relationship between Q, and this relationship by the following factors: the smaller the tire rolling losses usually have smaller damping effect, therefore, poor tire ride comfort and noise . Loss of rolling roll is not only loss of the object itself, but also accompanied them caused the problem. To solve the problem of rolling loss, tire and vehicle industries resort is needed. Possession of a small forward dynamic resistance higher inflation pressure surface lighter weight boat tire knot dirty pick overall performance than the ride comfort and handling Ping Wei of tire wear wet brake arm Sharp voice of the durability of Figure l7 reduction of the rolling loss 8 Conclusion performance tires to reduce tire rolling losses, the tire industry research work has been a great success. And expected to get further development. We present and future research and development is to develop guiding principles for effective fuel saving tires.
