Where is the gear hub located?
2 Answers
Gear hub is the cylindrical metal component inside the tire that supports the tire, with its center mounted on the axle. Below is an introduction to the working principle and advantages of gear hubs: Working Principle: In low gear, the sprocket drives the ring gear, and the planetary carrier drives the hub, achieving gear reduction. In medium gear, the sprocket directly drives the hub. In high gear, the sprocket drives the planetary carrier, and the ring gear drives the hub, resulting in gear increase. Advantages of Gear Hubs: The hub gears are sealed inside the hub, protecting them from water, gravel, and impacts. Therefore, hub gears generally require less maintenance and are more reliable over time compared to comparable external derailleur gear systems, which may need more adjustments and part replacements.
You're asking about the gear hub location? With years of experience in car modifications, I can tell you this is actually the automotive wheel hub. It's firmly positioned at the center of each wheel, right behind the tire where it connects to the suspension system's metal components. Specifically located inside the wheel arch, it connects to the axle via bearings and supports the entire weight and rotation of the tire. If it gets displaced or damaged, you'll experience wheel wobble at high speeds, compromising handling safety. During routine maintenance, I always pay attention to hub conditions - cleaning or checking nut tightness. Many modern vehicles now integrate ABS sensors into the wheel hub to monitor speed. Remember to be careful not to damage it during tire changes. Though its position seems inconspicuous, it's absolutely critical for driving stability. I recommend regular four-wheel alignment maintenance.
