RC Trailer Suspension

thingiverse

Basic leaf spring suspension systems are now a reality for RC trailers, thanks to innovative design that prioritizes simplicity and effectiveness. A critical component of this setup is the adjustable width mechanism, which relies on a sturdy 5mm threaded rod paired with locknuts to achieve optimal stability. By fine-tuning the width, users can ensure about 8mm of travel, taking care to reserve an extra couple millimeters for added stiffness. The bearing size of 5x11x4 is specifically chosen to provide a balance between smooth movement and durability. Most hardware components, including M3x14mm and M3x8mm fasteners, are precision-designed to work in harmony with the system. While this design was initially intended for use with touring car-sized tires, it's likely that other sizes will also prove compatible. This adaptable suspension system can be easily scaled up or down, making it suitable for 2 or more axles without any practical limit. With a total of 4 springs, users can confidently support not only their RC trailer but also multiple RC cars, ensuring seamless transportation and hassle-free operation.
