?
1. Domestic new energy vehicles:
1) Battery production and assembly: The ball screw assembly is widely used in the winding and stacking processes of cell manufacturing and the module installation of battery packs to ensure the production accuracy and assembly quality of batteries.
?
2) Body manufacturing: During body welding, ball screws and nuts are used to drive welding equipment to position welding points accurately. In parts assembly, they help install components such as motors, reducers, and suspensions smoothly and accurately.
?
3) Final assembly stage: During interior installation, Precision Ball Screws assist in accurately positioning components such as dashboards and seats. The installation and debugging of opening and closing components such as doors and trunks also use the?Lead Screw mechanism?to ensure smooth and accurate control of opening and closing actions. ?
2. Tesla vehicles:
1) Super factory automated production line: In chassis assembly, the ball screw set precisely drives tooling fixtures to complete the combination of chassis parts. Each part's splicing and fixation are strictly controlled during the automated assembly of the body frame.
?
2) Battery manufacturing and integration: In the self-developed battery production process, linear motion ball screws precisely control the actions of each process in cell production. When assembling battery modules and integrating battery packs into the vehicle body, they ensure the accuracy of each module's position and connection.
?
3) Intelligent driving related: When installing sensors and control units of intelligent driving systems, the precision ballscrews achieve millimeter-level accurate positioning to ensure the reliable operation of intelligent driving functions.
?
4) Humanoid robot field: In the research and development of the humanoid robot Optimus, planetary roller screws are used as the core driving components of robot joints, enabling it to complete complex actions and tasks.
?
二、Application depth and innovation
?
1. Domestic new energy vehicles: The application of ball screws kit is mostly concentrated in traditional automotive manufacturing links such as batteries, bodies, and final assembly. The application in some emerging technologies and special design fields is relatively less, and the overall application mode is relatively conventional. However, with technological development, continuous exploration and innovation are also underway. For example, some car companies have begun to try more advanced lead screw technology applications on high-end models or concept cars.
?
2. Tesla vehicles: In addition to applications in traditional manufacturing links, Tesla has also deeply expanded the application of Lead Screws in cutting-edge fields such as humanoid robots, demonstrating its leadership in technological innovation and cross-domain applications. In addition, Tesla's front windshield wiper of the Cybertruck adopts an electromagnetic moving block and guide rail design, abandoning traditional motors and linkage mechanisms, which is also a unique innovative application. ?
三、Screw production type preference
?
1. Domestic new energy vehicles: Ball screws are widely used. Some car companies have also begun to gradually explore the application of higher-precision and high-performance lead screws such as planetary roller screws, but the overall proportion is relatively small.
?
2. Tesla vehicles: In the humanoid robot Optimus, planetary roller screws are used as the joint driving components, giving full play to their advantages of high transmission efficiency, high precision, long service life, and strong load capacity. However, in its automotive products, the specific application details of different types of lead screws have not been fully disclosed.
?
四、Supply chain source
?
1. Domestic new energy vehicles: The supply sources of screw products for domestic new energy vehicles are relatively wide, including both domestic professional screw manufacturers and some internationally renowned brands. In recent years, with the development of the domestic screw industry, the application proportion of domestic screws in the field of new energy vehicles has gradually increased. Some domestic enterprises, through independent innovation and technological upgrading, have been able to provide high-quality screw products for domestic new energy vehicles. Enterprises such as Beite Technology and Best have actively laid out in related fields and have achieved a certain market share.
?
2. Tesla vehicles: The screw production supply chain for Tesla's automotive products is relatively more global, and it has established long-term and stable cooperative relationships with internationally renowned screw suppliers. At the same time, Tesla's own strong technological research and development and supply chain integration capabilities give it a high degree of discourse and flexibility in choosing screw suppliers, enabling it to ensure the quality and supply stability of screw products and also playing a positive role in promoting the development and innovation of screw technology.
