The rim is the metal component that mounts and secures the tire, and is also an important component of the wheel. It and the tire together form a complete wheel system , and together with the tire, it plays a key role in vehicle operation. Its main functions can be summarized as follows:
1. Support and fix the tire : The rim provides the correct installation position and support surface for the tire, ensures that the bead fits tightly, and prevents the tire from sliding or falling off when driving or under heavy load.
2. Carrying and transmitting loads : The weight of the vehicle, the weight of the cargo, and the impact force from the ground will be transmitted to the rims through the tires, and then transmitted to the axles and chassis by the rims.
3. Ensure airtightness : In tubeless tires, a reliable seal must be formed between the rim and the bead to prevent air leakage.
4. Transmit driving force and braking force : The driving force of the engine and the braking force of the brake are transmitted to the tire through the rim and finally act on the ground.
5. Maintain vehicle stability : Appropriate rim width, diameter and offset can make the tires evenly stressed, ensure smooth vehicle driving, and reduce abnormal tire wear and deviation.
6. Easy to disassemble and maintain tires : Multi-piece rims (such as 3PC and 5PC structures) are widely used in construction machinery and mining trucks, greatly improving the efficiency and safety of disassembly and assembly of large-size tires.
7. Protect tires and extend their life : A rim with a reasonable structure can prevent the tire bead from being excessively squeezed or loosened, and reduce damage caused by improper assembly.
The functions of the rim can be summarized as "support and fixation, load bearing and force transmission, sealing and leak prevention, stability and safety, and easy maintenance." It is not only the "skeleton" of the tire, but also the key link in the transmission of power and weight of the entire vehicle.
In the field of Otr Rim manufacturing, we are committed to building an integrated manufacturing system for the entire industry chain to comprehensively improve product quality and delivery efficiency.
The factory achieves independent control over the entire process from raw material production , steel cutting, forging and forming, machining, to welding and assembly, surface treatment, testing and packaging, and builds a highly integrated, intelligent and efficient production chain.
We carefully select high-strength, low-alloy structural steel to ensure that each wheel rim is stable and reliable under extreme operating conditions such as mines, ports, loading stations, and excavation. Automated welding equipment and a rigorous quality control system enable highly consistent and precise mass production. Strict control of every process ensures dimensional accuracy and product consistency. Advanced electrostatic spraying and electrophoretic coating processes not only enhance corrosion resistance but also ensure a long lifespan and a high-quality appearance.
With over two decades of experience, we have served hundreds of OEMs worldwide and are the original equipment manufacturer (OEM) for renowned brands such as Volvo, Caterpillar, Liebherr, and John Deere in China. Our products include 3PC and 5PC rims, and are widely used in heavy equipment such as wheel loaders, rigid mining trucks, motor graders, and articulated trucks .
We have a long history of designing and manufacturing high-quality rims for a variety of off-highway vehicles. Our R&D team, comprised of senior engineers and technical experts, is focused on the research and application of innovative technologies, maintaining our leading position in the industry. We have established a comprehensive after-sales service system, providing timely and efficient technical support and after-sales maintenance. Every process in our rim production adheres to strict quality inspection procedures, ensuring that each rim meets international quality standards and meets customer requirements.
TRACTION's rims have undergone rigorous validation by host customers, and TRACTION has extensive and loyal partners in the global market.
We have extensive involvement in the fields of construction machinery, Mining Rims,forklift rims, industrial rims, agricultural rims, other Rim Components and tires.
