The following are the applications of linear screws and guide rails in Tesla cars:
?
1. Production and Manufacturing Link
?
1) Body Assembly: On the body assembly line of Tesla's super factory, linear motion screw and guide rail systems are widely used in automated production equipment. For example, when splicing and welding various parts of the body frame, high-precision guide rails provide a stable and accurate movement path for welding robots, ensuring the accurate position of welding points, and thereby improving the strength and integrity of the body structure.? linear screws are used to drive fixtures and tools to accurately adjust and fix the position of body parts to ensure that the assembly accuracy of the body reaches a high standard.

2) Battery Production and Installation: In the battery manufacturing process, ball screws and linear guides play a key role in ensuring battery production quality and assembly efficiency. On the battery cell production line, linear ballscrews can precisely control process actions such as winding and stacking to ensure the dimensional accuracy and internal structure consistency of battery cells, thereby improving battery performance and safety. In the assembly link of battery PACKs, linear motion guideways provide accurate guidance for transporting and positioning battery modules. The Precision Ball Screws are responsible for accurately installing battery modules into battery packs to ensure that the connections between battery modules are tight and arranged neatly, which is conducive to energy management and heat dissipation of battery packs. ?
2. Automotive Components and Systems
?
1) Seat Adjustment System: The seat adjustment function of Tesla cars usually relies on ball screw transmission. By electrically or manually driving the ball screw to rotate, the rotational motion is converted into linear motion, thereby realizing multi-dimensional adjustments of the seat such as front-back, up-down, and backrest angle. The high precision and high rigidity of ball screws and nuts can ensure the smoothness and accuracy of seat adjustment, providing passengers with a comfortable riding experience and also meeting the personalized needs of different drivers for seat positions.
?
2) Steering System: Some Tesla models adopt an electric power steering system. In which, linear motion ballscrews and guide rails serve as key transmission components to transmit the power of the motor to the steering mechanism and realize vehicle steering control. The low friction and high-efficiency characteristics of high-accuracy ball screws help improve the response speed and handling performance of the steering system, enabling drivers to control the driving direction of the vehicle more accurately and enhancing driving safety and comfort.
?
3) Braking System: In the braking system of Tesla cars, ball screws can be used to control the movement of brake calipers and achieve precise braking pressure adjustment. Especially in the electronic braking system, the ball screw set works in coordination with components such as motors and sensors to quickly and accurately adjust the braking force according to the driving state of the vehicle and the braking needs of the driver to ensure the braking effect and stability of the vehicle.
?
4) Intelligent Driving System: When installing various sensors and control units of the intelligent driving system, ball screw products can achieve millimeter-level precise positioning to ensure that these key components are in the best working position and ensure the reliable operation of intelligent driving functions. For example, the installation of sensors such as cameras and radars requires ball screws and guide rails to ensure the accuracy of their installation angles and positions, thereby providing accurate data support for vehicle environmental perception and decision-making control.

3. Special Design and Innovative Applications
?
1) Cybertruck Wiper System: The front windshield wiper of Tesla's Cybertruck adopts an electromagnetic moving block and guide rail design. This innovative wiper system abandons the traditional motor and linkage mechanism. The wiper arm is driven by electromagnetic force to move along the guide rail, realizing full coverage of the entire windshield without dead angles. This not only improves the cleaning effect but also reduces operating costs and reflects Tesla's innovative spirit in automotive design.
