Car rear wheel hub becoming hot may be due to prolonged friction between the tire and the ground or extended braking. Below is a detailed introduction about car wheel hubs: 1. Overview: The wheel hub (Car-Rim) is the central part of the wheel where the axle is installed, also known as the "wheel rim" or "steel rim." Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they may corrode and deform, posing safety hazards. 2. Classification: Wheel hubs can be categorized into steel wheel hubs and alloy wheel hubs based on material, each with its own advantages and disadvantages. The main advantage of steel wheel hubs is their simple manufacturing process (usually using casting techniques, whereas aluminum alloy wheel hubs are typically produced using low-pressure casting), relatively lower cost, and stronger resistance to metal fatigue.

How to Quickly Start a Motorcycle?

Key is to find the point of releasing the clutch and applying the throttle. The clutch engagement depth varies for different motorcycles, so it cannot be generalized. The trick is not to fully release the clutch before applying the throttle; instead, apply the throttle when the clutch is about one-third released. The throttle doesn't need to be too large, as excessive throttle can choke the engine. Below are some motorcycle riding tips: 1. Learn to slow down when turning. Generally, there's no need to pull in the clutch and downshift when turning; simply ease off the throttle to slow down. 2. Master the coordination between the clutch and throttle: The most crucial aspect is controlling the coordination between the clutch and throttle. When downshifting uphill, release the clutch in one smooth motion to avoid engine issues. It's essential to familiarize yourself with the clutch engagement point of your specific bike, as the engagement distance varies from one motorcycle to another.
