What does TC skeleton oil seal mean?

TC oil seal is a mechanical component used to seal oil (oil is the most common liquid substance in the transmission system, and it also generally refers to liquid substances). It isolates the parts that need lubrication in the transmission components from the output parts, preventing the leakage of lubricating oil. Additional information: 1. Meaning of oil seal: Oil seal (oil-seal) is the customary term for general sealing components, simply put, it is the sealing of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and it also generally refers to liquid substances). It isolates the parts that need lubrication in the transmission components from the output parts, preventing the leakage of lubricating oil. The sealing components used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. 2. Representation form: The representative form of oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. Generally, when people refer to oil seals, they often mean this type of TC skeleton oil seal.

Recently, I've been researching automotive seals, and the TC skeleton oil seal is a core component inside the turbocharger. Simply put, it acts like an oil guard, consisting of a rigid metal skeleton wrapped with a soft rubber sealing ring. Its main job is to prevent engine oil from leaking out when the turbo spins at high speeds. Think about it—turbochargers can rotate at tens of thousands of RPM with high oil pressure. Without this oil seal, oil could seep into other parts of the engine, causing leaks. Over time, this not only dirties the chassis but may also lead to low oil pressure, turbo overheating, or degraded engine performance. My car had this issue before—a minor problem turned into a major repair, costing a lot of money. I recommend car owners to regularly check under the hood for oil stains. Routine maintenance and inspections can save both hassle and money.

What is the safe distance between cars?

The safe distance between cars varies depending on the speed: 1. When the speed is above 100 kilometers per hour, the safe distance should be more than 100 meters; 2. When the speed is above 60 kilometers per hour, the safe distance should be equal to the speed, for example, at 60 kilometers per hour, the safe distance should be more than 60 meters; 3. When the speed is 50 kilometers per hour, the safe distance should be more than 50 meters; 4. When the speed is below 40 kilometers per hour, the safe distance should be more than 30 meters. The safe distance between cars is the necessary gap that the following vehicle maintains to avoid accidental collisions with the vehicle in front while driving.

How many rear fog lights does a car have?

There are one or two rear fog lights on a car. Fog lights are red or yellow, as these two colors have longer wavelengths and stronger penetration. The method to turn on car fog lights is: 1. Locate the light control lever below the steering wheel; 2. Find the fog light symbol and rotate the control ring; 3. Align the front fog light symbol to the 'on' position. The functions of car fog lights are: 1. Front fog lights are used to improve illumination when the road ahead is unclear and can alert oncoming drivers; 2. Rear fog lights help vehicles behind to spot the car in low visibility conditions. Situations for using fog lights include: 1. During heavy rain when the driver's visibility is blurred, making it difficult to assess the surroundings; 2. In foggy weather.

What causes the brake caliper not to retract?

The brake caliper not retracting could be due to not changing the brake fluid for a long time, causing internal rust in the brake caliper, or poor precision of the caliper leading to insufficient piston retraction. It might also be caused by a blockage in the brake caliper pipeline, requiring replacement of the brake fluid or related components. Dirt causing sticking: Check if the piston in the brake caliper is sticking due to dirt. Another possibility is that the guide pipe fixing the brake caliper is stuck, preventing the caliper from retracting. In this case, remove the brake caliper and polish it with fine sandpaper. Internal rust in the brake caliper: Not changing the brake fluid for a long time can cause internal rust in the brake caliper. Apply grease to the outside of the fixing screws of the brake caliper and suspension, then reassemble and polish with fine sandpaper. Poor precision of brake pads: If the brake pads have poor precision or are too thick, the piston may not retract fully. Before replacing the caliper, disassemble the new caliper completely, clean off the protective oil applied before leaving the factory with carburetor cleaner, and then apply medical Vaseline to the entire caliper cavity and piston before reassembling.

What is the reason for the clicking sound when stepping on the brake?

The reason for the clicking sound when stepping on the brake is the normal activation of the ABS. The working process of ABS involves a cycle of locking and releasing, keeping the vehicle in a state of intermittent rolling near the critical lock-up point. When the ABS is triggered by a sudden brake application, it produces a clicking sound, which is a normal phenomenon. In this situation, firmly pressing the brake pedal to the floor is sufficient. The function of the car's braking system is to reduce speed or bring the vehicle to a stop. Its working principle relies on the friction between the brake pads and the brake drum, as well as between the tires and the ground, converting the kinetic energy of the moving vehicle into heat energy through friction, thereby slowing down or stopping the vehicle.
