1. The flywheel product is made of standard HT250 material, the hardness of the matrix reaches 170-200HB, the ring gear part is made of standard 45# alloy steel, and the high-frequency quenching process is adopted. The hardness of the teeth can reach 48-58HRC, which makes the product more heat-resistant and wear-resistant. more durable.

2. Our company uses fully automatic CNC machine tools, machining centers, and dynamic balancing equipment in the processing process to ensure that the processing accuracy of the product is better, and it can reach the dimensional accuracy of the original car factory, so that the sound of the product is smaller and more stable when it is used. .

3. The truck flywheel is mounted on the engine's crankshaft and rotates at the same speed as the engine, forming a mechanical connection. Its primary function is to provide rotational inertia, ensuring a smooth and consistent power delivery to the drivetrain.

4. Export products are made of high-strength five-layer A-grade cartons, painted with anti-rust oil on the outside, and covered with anti-rust sealed bags to ensure that the products will not be rusted due to transportation problems.

Principle

When starting a car, the gear on the starter motor meshes with the ring gear on the starter flywheel and drives the flywheel to rotate. Since the flywheel is installed on the engine shaft, it drives the engine to rotate and start the car.
