What is the difference between double swingarm and single swingarm?

[DiSophia]

The differences between double swingarm and single swingarm include different advantages, characteristics, force-bearing points, prices, tire disassembly convenience, rigidity, and weight. Different advantages: The biggest advantage of a double swingarm vehicle is its flexibility, making it suitable for narrow spaces, while the body of a single swingarm vehicle is generally longer than that of a double swingarm. Different characteristics: The double swingarm has upper and lower beams on the large arm, welded into a frame structure, while the single swingarm features a single central beam structure. Due to the sufficient strength of this single beam, its structural strength and rigidity are also excellent. The single swingarm is simpler to manufacture, easier to correct deformation after welding, and provides better visibility for the driver, which is why the vast majority of wheel loaders adopt the single swingarm structure. Different force-bearing points: The single swingarm has only one force-bearing point, distributing force more evenly and with greater power compared to the double swingarm. Different prices: Most household or mid-to-low-end motorcycles on the market use a double swingarm design due to its relatively simple structure, resulting in lower manufacturing costs and more affordable prices. In contrast, single swingarms are typically found on high-end, large-displacement motorcycles, which have a higher purchase threshold and are therefore more expensive. Different tire disassembly convenience: Double swingarm vehicles require the removal of fixtures on both sides to take off the wheel, which is time-consuming and labor-intensive. Single swingarm models were originally designed for motorcycle racing, allowing tire changes by removing just one side, saving significant time during races and making daily maintenance more convenient for users. Different rigidity: Since single swingarms were initially developed for racing, where motorcycles have large displacements, heavy bodies, and require prolonged high-speed operation, they demand higher precision in machining and superior materials. Double swingarms, due to their inherent stability, do not require as much effort in material selection, making single swingarm models in the same class generally more rigid. Different weights: Single swingarms need to use higher-strength materials and have more complex constructions, theoretically making them heavier than double swingarms, which are typically lighter.
