This product is a drive shaft suitable for small cars with an axle load of 0.5-2 tons. Its core function is to connect the gearbox and drive wheels, and stably transmit rated torque of 50-300N · m. Compliant with ISO/TS 16949 certification and ECE R122 safety standards, it adopts a cross universal joint+45 # high carbon steel shaft design to reduce driving vibration, and the working temperature covers -40 ℃ -120 ℃. After fatigue testing, 1 million cycles without damage, suitable for daily commuting, long-distance and other scenarios, ensuring efficient and reliable power transmission.
Our transmission shaft is made of high-strength steel, aluminum alloy, and even advanced carbon fiber composite materials. Compared to traditional solid steel transmission shafts, carbon fiber composite transmission shafts can achieve weight reduction of up to 50%. This not only reduces the overall quality of the vehicle, but also helps improve fuel economy or the range of electric vehicles (some tests have shown that it can increase the overall energy efficiency by up to 3%). It can also reduce rotational inertia, making the vehicle accelerate more quickly and respond more sensitively.
In response to the characteristics of instantaneous high torque output in electric vehicles, our transmission shaft has undergone structural strengthening and material optimization. Its torsional stiffness is increased by about 20% compared to traditional products, and it can easily cope with the huge stress generated during motor starting and regenerative braking, with significantly improved fatigue strength. The product undergoes rigorous bench testing and road simulations to ensure long-term reliability and durability under harsh operating conditions.
We effectively suppress the vibration and noise caused by the transmission shaft through precise dynamic balance correction (usually requiring a residual unbalance of less than 0.5 g · mm/kg) and optimized universal joint design (such as using NIO's 8-ball universal joint or double offset universal joint (DO joint) technology). This provides a quieter, smoother, and more comfortable driving environment for passengers inside the car, especially in the quiet electric cabin where the experience is significantly improved.
Our products are designed and manufactured strictly in accordance with OEM specifications and standards, ensuring a perfect match and direct installation with the target vehicle model. We can provide high-quality transmission shafts that are precisely adapted to restore the original factory performance and driving feel of your car.
In line with the trend of intelligence, some high-end models can integrate sensors to monitor the torque status of the drive shaft in real time. This provides a hardware foundation for achieving predictive maintenance and more advanced chassis control systems in the future, supporting the development of autonomous driving technology and further enhancing the safety and technological sense of vehicles.

Here are specific application scenarios of drive shaft:
For cars commuting in the city every day, the transmission shaft needs to cope with frequent start stop, acceleration, deceleration, and turning. Our transmission shaft is made of high-strength alloy steel or advanced composite materials (such as carbon fiber, believed to improve energy efficiency), which have excellent fatigue resistance and durability, and can effectively resist the alternating stress impact under urban road conditions. Its precise dynamic balance processing (all undergo dynamic balance testing and adjustment before leaving the factory) ensures smoothness at low speeds and acceleration, reduces vibration and abnormal noise, improves driving comfort, and makes your daily commuting easier and more enjoyable.
The dynamic balance performance of the transmission shaft is crucial during high-speed cruising. Our transmission shaft undergoes strict dynamic balance detection and correction (with extremely low residual unbalance), which can maintain extremely low vibration levels when rotating at high speeds (such as over 100km/h), avoiding steering wheel or body shaking, ensuring the stability and safety of vehicle driving. This provides a quiet, smooth, and reliable driving experience for car owners who enjoy long-distance driving, frequent business trips, or road trips.
For vehicles that occasionally need to leave paved roads (such as rural dirt roads and construction sections), or for car owners living in rainy, snowy, and high humidity coastal areas, the transmission shaft needs to have good dust, water, and corrosion resistance performance. Our transmission shaft expansion sleeve adopts high-quality sealing design and rust prevention treatment (such as overall coating with nylon material), which can effectively prevent mud, water vapor, and salt from entering the internal splines and universal joints, reduce abnormal wear and corrosion, extend the service life in harsh environments, and provide stronger protection.
For enthusiasts who pursue driving pleasure, occasionally engage in intense driving or vehicle modification, the transmission shaft needs to be able to withstand greater instantaneous torque and torsional stress. Our product adopts reinforced design (such as high pressure angle involute short tooth spline) and high-performance materials, providing higher torsional stiffness and strength, ensuring direct and efficient power transmission under conditions such as rapid acceleration and high-speed cornering, reducing deformation and energy loss, and providing reliable support for sports and performance car enthusiasts.
As the service life and mileage of the vehicle increase, the original transmission shaft may experience problems such as excessive wear and clearance of the universal joint, loose spline fit, loss of dynamic balance, or surface corrosion, leading to vibration, abnormal noise, and even power transmission interruption during driving. Our transmission shaft, as a high-quality OE replacement, can perfectly adapt to various common sedan models, effectively restoring the vehicle's original transmission smoothness and power response speed. It is an ideal choice for repairing and maintaining old vehicles.
Always replace drive shafts in pairs to maintain balanced performance. Use a calibrated torque wrench to tighten all fasteners to OEM specifications (typically 180-220 N·m for axle nut). Ensure proper alignment during installation to prevent vibration issues. After installation, perform a road test at various speeds to check for vibrations or unusual noises. Proper installation following OEM procedures ensures the drive shaft achieves its rated service life and maintains vehicle safety standards. All our drive shafts undergo precision balancing testing to meet ISO 1940 G6.3 balance standards for smooth operation.
