Chassis subassemblies involve safety-critical parts such as suspension, subframes, and drive shafts, with multiple bolt sizes, high torque, and tight takt time. Leetx intelligent tightening systems with assist arms provide accurate torque control and full-process traceability.
Tire installation is a critical final-assembly operation requiring high takt time, high torque, and tight consistency. Leetx multi-spindle wheel tightening equipment uses five-axis synchronous servo control and torque-angle closed-loop control to prevent missed or incorrect tightening and maintain traceable wheel-fastening quality.
In the body shop, hinges, latches, and closure-panel joints require strict angle and torque consistency. Leetx intelligent tightening systems provide high-precision torque control and flexible tool positioning to ensure accurate location and reliable fastening for doors, hood, and decklid.
The axle center nut is a load-bearing and driveline-critical fastening point with high torque, restricted access, and strict depth/concentricity requirements. A high-rigidity servo tightening spindle with torque-angle closed-loop control precisely manages rundown depth and final torque for safe, consistent, traceable joints.
Torque accuracy affects hood gap/flush, closing feel, and latch reliability. Because operators often work overhead, the station requires lightweight tools, consistent torque delivery, and traceable tightening data.
Roof-area fastening for sunroofs, headliners, air ducts, and harness or pipe routing is performed in tight overhead spaces. Torque variation can cause squeaks, air leaks, or loosening, so lightweight tools, torque accuracy, and full traceability are essential.
Body brackets such as IP cross-car beams, subframes, and engine-compartment brackets have many high-torque joints in confined spaces. A cordless smart electric wrench enables flexible access, controlled torque, and data upload for traceable fastening.
Structural chassis members such as rocker panels and floor rails have high-torque joints in long, narrow spaces under tight cycle time and traceability requirements. A handheld 36 V smart electric wrench supports high-torque output, data return, and flexible fastening on complex body-shop stations.
The front subframe carries the powertrain and suspension arms and is critical to load transfer and NVH. A column-mounted intelligent tightening machine with a balance arm and torque-angle dual control delivers efficient, accurate, and fully traceable chassis assembly.
