What is the iron ring of a tire called?

The iron ring of a tire is called the wheel hub. The wheel hub, also known as the rim, steel ring, wheel, or tire ring, is a cylindrical metal component that supports the tire from the inside and is centrally mounted on the axle. It is important to pay special attention to the maintenance of the wheel hub while driving, as it is prone to accumulating dirt. If not cleaned for a long time, it may corrode and deform, potentially leading to safety hazards. Car tires are one of the essential components of a vehicle, directly contacting the road surface. Together with the car suspension, they help absorb shocks during driving, ensure good adhesion between the wheels and the road, improve the car's traction, braking, and off-road capabilities, and bear the weight of the vehicle.

The wheel hub is the metal ring part of the tire, which is essential for every car. I feel the role of the wheel hub is particularly crucial—it connects the car body and the tire, supporting the entire wheel's operation. I only realized the importance of the wheel hub when I last changed tires—aluminum alloy wheel hubs are lighter, making driving more fuel-efficient, while older steel wheel hubs are sturdy but prone to rust. I remember once after a bumpy ride on the highway, the wheel hub got slightly deformed, and the tire started leaking, costing me extra repair fees. So, I recommend avoiding potholes while driving and checking the wheel hub's condition during annual maintenance, such as cleaning the surface to prevent corrosion or cracks. This not only extends its lifespan but also avoids unnecessary expenses.

Are Car Blind Spot Mirrors Useful?

Blind spot mirrors are indeed useful as they provide drivers with a wider field of view, significantly reducing blind spots. Here is a detailed introduction to blind spot mirrors: 1. Concept: Also known as convex mirrors or blind spot mirrors, they utilize the principle of convex reflection to minimize blind spots while driving. During reversing, these mirrors allow drivers to see the rear wheels of the vehicle, enhancing safety and control. 2. Disadvantages: However, blind spot mirrors are not without drawbacks. While they offer a broader view, they also cause significant image distortion and distance inaccuracies. Additionally, their attachment to the side mirrors may appear somewhat awkward.

What does gasoline + 48V mild hybrid system mean?

Gasoline + 48V mild hybrid system refers to a car engine equipped with a 48V mild hybrid system. Vehicles with this system have a 48V electric motor attached to the engine periphery. This motor can start the engine and generate electricity while the engine is running, thereby improving the vehicle's fuel economy. Below is an expanded introduction to the gasoline + 48V mild hybrid system: 1. More and more vehicles are adopting the 48V mild hybrid system due to its simple structure and relatively low cost. 2. There are various types of 48V mild hybrid systems, with most vehicles placing the 48V motor in front of the engine. 3. The installation position of the 48V motor can have a certain impact on the vehicle's performance.

Is Idling Harmful to a Car?

Long periods of idling can cause certain damage to a car. Here is relevant information: 1. The main harm is that prolonged or frequent idling can easily lead to carbon buildup in the engine cylinders, and the throttle may also be affected. Due to the low engine speed and low intake efficiency during idling, combustion is not very complete, making it prone to carbon buildup. More importantly, the accumulated carbon cannot be expelled and continues to accumulate in the cylinders and intake passages, significantly accelerating the rate of carbon buildup. 2. When carbon buildup reaches a certain level, it can reduce the car's power performance and, over time, easily cause engine wear. During idling, the vehicle does not perform any external work. In this state, the engine only overcomes its own resistance, so the engine should be turned off during prolonged waiting periods.

What is the issue with restricted transmission function?

Transmission function is restricted because the transmission control unit detects signal loss and takes protective measures. Here is the relevant content introduction: 1. The transmission is a mechanism used to change the speed and torque from the engine, which can fix or change the gear ratio between the output shaft and the input shaft, also known as the gearbox. 2. The functions of the transmission are: (1) Change the transmission ratio to expand the range of torque and speed changes of the driving wheels. (2) Enable the car to reverse while the engine's rotation direction remains unchanged. (3) Use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitate gear shifting or power output.

What does it mean when the water temperature warning light on the car dashboard comes on?

The reasons for the water temperature warning light to illuminate are: 1. The vehicle is low on coolant. 2. The engine is experiencing overheating issues. When the water temperature warning light comes on, park the car in a safe location and check if the coolant level is low. If it is low, replenish it and inspect for any leaks. If leaks are found, repairs should be made as soon as possible. If the coolant level is not low, it is likely that the vehicle's water temperature is too high, in which case you should contact a professional mechanic for inspection and repair. Do not continue driving under these circumstances to avoid engine damage due to excessive temperature.

How often should a private car be inspected after 6 years?

After 6 years, private cars need to be inspected every 2 years. Here are the inspection regulations for private cars: 1. After the implementation of the new vehicle inspection regulations, cars between 6 and 10 years old must be inspected every 2 years. 2. At the 6th and 8th year, the vehicle must undergo an on-site inspection. 3. Private cars older than 10 years still follow the original inspection cycle, meaning cars between 10 and 15 years old must be inspected once a year, and cars older than 15 years must be inspected every 6 months. 4. During the annual inspection, the vehicle owner can apply for an inspection compliance mark at the local vehicle management office within 3 months before the expiration of the current inspection period.
