Research & Design

The technology development of the PCR & LTR products stands for the main development trend of technology development of the tyre industry. With the perfect product R&D system, we've reached higher technology levels in the industry in many aspects such as tyre structure, tyre pattern, tyre compound, environment-friendly tyre and so on.
Advanced technology of structure designing
The overall designing of the tyre carcass with the technology of ground-contacting stress balance and computer ACD, can make the ground stress distribute in a more balanced fashion, so as to minimize the stress of unit ground-contacting. This means the wearing of the unit ground will be the least, thus affording much higher mileage.
Special methods of improving the non-contact part of the shoulder greatly decrease the accumulation of excessive heat in this part. With the dropping of tread temperature, the fatigue of tread rubber has been reduced greatly, which ensures durability and high-speed. The latest tire contour design simulated by the computer greatly reduces the energy generated by the strain of the belt and fetal.
The most optimizing design of tyre shoulder can avoid the concentration caused by the abnormal pressure of the punctured tyre. Highly flexible steel belt and seamless tread cap effectively improves durability and controlling.
Scientific pattern developing technology
We use dynamic simulation and optimization technology as the key method in developing the patterns. Using supercomputer dynamics imitates the operation of the tyres under various driving conditions targeted to develop the patterns, including wear resistance, noise, riding comfort, rim collocation, driving balance, the durability and rolling resistance.
We use the software STACS to simulate the reaction of pattern on the road under the situation of tire acceleration, braking, swerving and other driving force.
Using CASPAN system to measure the contact shape and pressure ensures that when the tyres contacts the ground, the rigidity of the rubber remains consistent and vibration amplitude tends to balance, so as to reduce the noise which is caused by the pattern.
Special compound designing technology
1.Special tyre tread compound design effectively lubricates the friction between the rubber molecules, so as to reduce the energy losses, lower rolling resistance, and save fuel consumption.
2.Through the extension of rubber material of the chain of carbon molecules with structure, improving the durability of the tires can also improve the wear resistance of tyre; meanwhile we use the special silicon tyre tread compound technology to greatly enhance the grip, and keep the performance of saving fuel consumption.
Focusing on the China market, the biggest production and consumption nation of TBR tyres, will enable us to improve our product and technology efficiently. BBT is the technical system developed in our last 10 years' effort on R&D.
BBT technical system refers to an effort to improve overall performance on BEAD, BELT, TREAD tyres and other critical parts, by laboratory testing and in-site tracking of the road test.This allows understanding and improvement of the timely issue of emerging technologies, so as to continuously enhance the overall performance tyres used to make our company more responsive to all-steel products in a variety of road environments.
BBT technical advantage A
By adjusting the layout of bead steels, the hardness of fillers, close fit with bead matrix, and the height of turn up of the body ply, the beads are strengthened, then it realizes the smooth rigid transition between the hard bead and the soft side wall, which makes the flexible points in the sidewalls concentrative near the horizontal axis of the section to give the sidewall friction with the wheel rim to prevent the stress concentration in the bead position and delaminating, splitting or breaking, so as to achieve durable parts by improving the bead resistance, load performance objectives.
BBT technical advantage B
To enhance the rigidity of the cap for the superior wear-resistance performance; To enhance the rigidity of the shoulder to ensure the stable dimensions of tyres when they are running at high speed, and greatly reduce belt suffered heat and stress and to reduce the possibility of occurrence of separation on the shoulder, and better retreaded performance. To adjust rubber performance on belt to meet the bonding properties of both dynamic and thermal states and tyre production process requirements, improve the stable quality, the performance to be stretched and strengthened, flex-fatigue resistance and high performance anti-aging by improving adhesive properties on tie-in stripe, good heat-resistance and fatigue resistance is achieved, as well as low heat generating and high anti delaminating properties so as to extend the tyre life.
BBT technical advantage C
By reducing the curvature of cap, the ground-grip power on cap is raised, thereby enhancing the wear resistance of tire; By increasing the width of the contact surface, the tyre wear and grip performance is enhanced; Cap Rubber applies the imported smoke sheets 3 # and Cabot N115 carbon to improve the cap compound and related formulations of chemical agents, decrease the movement and creep between tyre cap and the ground, enhance the traction and lateral force so as to make the cap increase the wear resistance, anti-cutting performance, tear-resistant and anti-adhesion properties and extend the service life of the tyre; Base rubber applies the low-heat, high-adhesion rubber formulation to effectively reduce the operating temperature and improve the performance of high-speed tyres
