1. Continuous Power Transmission
As the core power transmission component of the JF015 CVT transmission, the chain belt realizes continuous power transfer between the driving pulley and the driven pulley. By adjusting the distance between the pulleys, it achieves stepless variation of the transmission ratio, eliminating the power interruption caused by gear shifting in traditional transmissions. This ensures smooth power output throughout the driving process, which is the key to the CVT transmission's signature smooth shifting experience .
2. NVH Performance Optimization
The metal belt structure of the JF015 chain belt has excellent vibration absorption performance . During high-speed operation, it reduces the noise and vibration generated by meshing transmission, significantly improving the vehicle's NVH (Noise, Vibration, Harshness) performance . Compared with traditional gear transmission, it avoids the impact noise caused by gear engagement, creating a quieter and more comfortable driving environment for passengers.
3. Auxiliary Fuel Consumption Reduction
Through high-efficiency power transmission and flexible ratio adjustment, the chain belt helps the engine maintain operation in the optimal fuel economy range under different working conditions. During cruising, it adjusts to a high transmission ratio to reduce engine speed; during acceleration, it switches to a low ratio to improve power response. This dynamic ratio optimization directly reduces unnecessary fuel consumption, making models equipped with the JF015 transmission more economical in daily use .
4. Stable Matching with Transmission System
The chain belt is fully compatible with the mechanical structure and control logic of the JF015 transmission. It cooperates with the transmission control unit (TCU) and pulleys to achieve real-time adjustment of the transmission ratio according to driving conditions (such as starting, accelerating, and cruising). This stable system matching not only ensures the accuracy of ratio switching but also reduces the wear of other transmission components, extending the overall service life of the CVT system .
1.High-Efficiency and Low-Slip Transmission
The JF015 transmission chain belt adopts advanced metal belt structure design, which significantly reduces elastic slip during power transmission. Its elastic creep ratio is controlled within 0.02% - 0.05% , far lower than that of ordinary belt drives. This high transmission accuracy ensures that the engine power is transmitted to the wheels with minimal loss, directly improving the transmission efficiency of the CVT system and laying a foundation for the vehicle's excellent fuel economy .
2.Optimized Torque Adaptability
Tailored for the CVT7 (JF015E) transmission system, this chain belt is specifically designed to match small-displacement engines with torque ranges of 110-166 N·m . It perfectly adapts to the output characteristics of engines like Nissan's HR15DE 1.5L engine (maximum torque 139 N·m) , avoiding problems such as slipping or excessive wear caused by mismatched torque bearing capacity. The precise torque matching also enhances the stability of power output during vehicle starting and acceleration.
3. Compact Structure with Extended Ratio Range
Integrated with the planetary gear auxiliary transmission mechanism of the JF015 transmission, the chain belt achieves an expanded transmission ratio range of up to 7.3 while reducing the overall size of the transmission by 10% . This compact design not only saves installation space in the engine compartment, making it suitable for compact models such as Nissan Sunny, Livina, and Sylphy 1.8L , but also broadens the gear ratio coverage, balancing low-speed torque output and high-speed fuel efficiency.
4. Durable Material and Manufacturing Process
The chain belt is made of high-strength alloy materials and manufactured through a sophisticated process combining mechanical processing and heat treatment . It undergoes steps such as material modification, stamping forming, heat treatment strengthening, and precision assembly, with key processes equipped with non-destructive testing to ensure component quality . This manufacturing standard enables it to withstand long-term friction and tension in the transmission oil environment, effectively extending its service life under normal driving conditions.
