What is a CV joint in a car?

Automotive CV joints are divided into inner CV joints and outer CV joints, also known as "constant velocity universal joints". They are crucial components in a car's drivetrain system, responsible for transmitting the engine's power from the transmission to the two front wheels, enabling the vehicle to drive at high speeds. A typical automotive CV joint consists of the following parts: bell-shaped housing, tripod bearing or steel balls, dust cover, retaining ring, and grease. The main inspection points for CV joints include: 1. Internal and external spline dimensions and thread sizes. 2. Checking the oil seal retaining dimension of the outer CV joint - this dimension usually varies among different CV joint models. 3. Verifying the correctness of the internal spline's circlip groove, as the width of the circlip groove affects the axial movement of the CV joint on the driveshaft after installation. 4. Material and heat treatment properties, which require specialized equipment for inspection.

What is the liquid in battery replenishment fluid?

Battery replenishment fluid is composed of purified water (or distilled water) with the addition of some pure sulfuric acid. Below is a detailed introduction: 1. Storage battery: The replenishment fluid for storage batteries is called deionized water. In the market, distilled water is often used as a substitute, and purified water can also be used. Such water does not contain conductive ions. It is important to note that tap water or mineral water cannot be used as substitutes, nor can the original sulfuric acid solution. 2. Replenishment fluid: If the battery is not durable, adding replenishment fluid is actually not reliable. Replenishment fluid has some effect on batteries that are not bulging, but the effect is limited. Adding replenishment fluid is harmless, but it does not solve the problem of battery durability. To truly extend the battery's lifespan and endurance, the key factors lie in daily maintenance and usage habits.

What is the reason for the lack of seat belt reminder voice in the Geely Vision X3?

The reason for the lack of seat belt reminder voice in the Geely Vision X3 is poor contact in the seat sensor. Car seat belts are devices designed to protect passengers and drivers by preventing airbag deployment injuries during severe impacts. Their function is to absorb impact energy, counteract inertial forces, and prevent or reduce the severity of injuries to occupants. The correct usage method for Vision X3 seat belts is: 1. Pull out the seat belt and securely fasten the buckle to ensure proper restraint; 2. Adjust the waist belt position to sit across the hips; 3. Adjust the shoulder strap position to cross diagonally over the clavicle; 4. Check seat belt security before driving to ensure proper functionality; 5. Press the release button while holding the buckle to retract the belt into the reel, then store the buckle in its designated position.

Which Consumes More Fuel: Snow Tires or All-Season Tires?

Snow tires consume more fuel than all-season tires. Here are the specific details about snow tires: 1. Pros and Cons: Snow tires are designed to adapt to low-temperature environments with enhanced friction. They are very soft, maintaining sufficient grip on snow-covered surfaces and offering good noise reduction. However, snow tires are not designed for summer use; they have poor heat dissipation, increasing the risk of tire blowouts. The soft structure of snow tires, optimized for snowy conditions, leads to rapid wear on summer roads and poor water drainage in the summer. 2. Suitable Environments: Winter tires are generally suitable for temperatures below 7 degrees Celsius. In regions with consistently high temperatures, they can still be used normally. When choosing tires, consider the usage environment. If the temperature changes are not significant, all-season tires may be a better option.
