Transmission device is the intermediate equipment that transfers the power from the power unit to the working mechanism. It consists of a clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The functions of the transmission system are: 1. Deceleration and torque increase; 2. Speed and torque variation; 3. Achieving reverse motion; 4. Interrupting the power transmission of the transmission system. The working principle of the automotive transmission system is that the power generated by the car engine is transmitted to the driving wheels through the transmission system, which has functions such as deceleration, speed variation, reverse motion, power interruption, inter-wheel differential, and inter-axle differential. Working in conjunction with the engine, it ensures the normal operation of the vehicle under various working conditions, providing good power performance and fuel economy.

In my years of driving experience, the transmission system serves as the power bridge of a vehicle, responsible for transferring the force generated by the engine to the wheels to get the car moving. It includes key components such as the gearbox, clutch, and drive shaft, which are as crucial as the joints connecting muscles to limbs in the human body. When driving a manual transmission, I noticed that clutch wear could cause gear-shifting jerks, affecting acceleration smoothness. Once on the highway, I nearly had an accident—fortunately, after stopping to inspect, I found it was due to aged transmission fluid. Regular maintenance, such as checking fluid levels and ensuring proper lubrication, can prevent such dangers. The health of the transmission system directly impacts fuel efficiency and performance: with good upkeep, the car runs longer and more economically; otherwise, it might break down midway, leading to costly repairs. Spending a few extra minutes during each maintenance session saves both safety risks and financial losses.

The transmission system is absolutely fascinating! It acts as the traffic control center of a car's power, directing the rotational force from the engine to the wheels. Key components like the gearbox adjust rotation speeds, the clutch engages or disengages power, and the differential allows wheels to rotate at different speeds during turns. Manual transmission enthusiasts experience an incredible sense of control when shifting gears to change gear ratios. However, during DIY repairs, I've noticed that loose drive belts or insufficient fluid levels can drag down the vehicle's responsiveness and cause fuel consumption to skyrocket. Regularly changing high-quality transmission fluid and inspecting connecting components are tasks you can handle yourself to improve efficiency and save money. Maintaining these parts prevents overheating failures and ensures driving pleasure remains intact. Remember, small issues accumulate into major breakdowns – timely intervention is key.

Why Can't You Use Mobile Phones at Gas Stations?

Mobile phones cannot be used at gas stations because when a phone is in use, it generates very weak discharges inside, producing tiny sparks. If the concentration of gasoline vapor in the air near the gas station is too high, these sparks could potentially cause an explosion, hence the prohibition of mobile phone use at gas stations. There are also several other precautions to note at gas stations: 1. Smoking is strictly prohibited: The surface temperature of a cigarette butt is generally between 200 to 300 degrees Celsius, which can easily ignite gasoline. The area around gas stations accumulates a large amount of flammable gas molecules, and even the smallest spark can trigger a fire or explosion; 2. Turn off the engine while refueling: During vehicle operation, the flow of intake and exhaust gases, as well as minor wear on electrical wiring, can generate static electricity or sparks, especially in humid weather when gasoline vapor concentration increases, significantly raising the risk of sparks igniting gasoline; 3. Avoid patting synthetic fiber clothing while refueling: Synthetic fiber fabrics are prone to generating static electricity, so do not pat your clothes when getting out of the car to refuel to avoid unforeseen dangers; 4. No vehicle repairs at gas stations: High-temperature engine parts or electrical leaks in the pressure system during car repairs can cause fires, especially dangerous are faults like electrical short circuits.

Can't the Brake Be Depressed When the Car Battery Is Dead?

When the car battery is dead, the brake cannot be depressed. The reasons why the brake cannot be depressed are as follows: 1. Air in the brake fluid line: Brake fluid is the medium for transmitting force in the braking system. If air enters the fluid line, the brake fluid under high pressure will appear insufficient in strength. Although there is still braking force, the maximum braking force is significantly weakened. In this case, the braking system should be promptly bled at a repair shop. 2. Brake fluid not replaced for a long time: If the brake fluid is not replaced in time, it will contain excessive impurities and moisture, which will affect the transmission of braking force. 3. Oil leakage or overly soft brake material: Generally, oil leakage from the brake master cylinder or brake fluid line will cause the vehicle's brake to become soft. If the brake material is too soft, its high-temperature stability will deteriorate, which will also cause the vehicle's brake to become soft.

What Causes Water Leakage in the Rear Seats of a Car?

The specific reasons for water leakage in the rear seats of a car are as follows: 1. Poor sealing of the trunk rubber strip leading to water leakage. 2. Blockage of the drainage holes in the trunk lid causing water to leak into the rear seats. 3. Poor sealing of the tail lights resulting in water leakage into the rear seats. 4. Inadequate sealing of the drainage holes beneath the spare tire well leading to water leakage into the rear seats. Solutions: 1. Clear the drainage holes: If you hear noticeable water sounds when opening/closing doors or while driving, it indicates water accumulation in the trunk. Simply use a thin wire or small screwdriver to clear the drainage holes. 2. Replace the sealing strips: Replace the sealing strips for the trunk and rear doors to enhance the car's sealing and prevent further water leakage. 3. Visit a 4S shop for inspection and repair.

Can uneven car touch-up paint be sanded?

If the car touch-up paint is not smooth after application, it can be sanded. Below is more information about car touch-up paint: 1. Process: The specific steps for touch-up paint include determining the repair area, assessing the damage level, applying protective measures, surface preparation, masking and degreasing, applying base coat, applying clear coat, blending the edges, baking, and finally sanding and polishing the paint surface. If loss of gloss occurs during polishing, it can be restored using a high-speed polisher with specialized polishing compound. 2. Precautions: The hardness of the touch-up paint is lower compared to the original factory paint, and high water pressure can damage the car's paint surface, so avoid using high-pressure water jets directly on the car body.

What Causes a Car Sunroof to Leak?

Car sunroof leakage can be attributed to the following reasons: 1. Clogged sunroof drainage outlets: When the drainage outlets are blocked, rainwater cannot flow smoothly and gradually seeps into the car. This issue mainly occurs when the owner neglects regular cleaning of the roof, allowing debris to flow with rainwater into the drainage outlets and clog them. To address this, you can use a wire to create a hook and remove the debris from the drainage holes, or visit a repair shop to use an air gun to blow out the debris. 2. Damaged sunroof seal: The sunroof seal is made of rubber and can deteriorate over time due to aging and repeated friction from the sunroof glass, leading to poor sealing and leaks during rainy weather. Regular inspection of the seal's condition is necessary, and damaged seals should be replaced promptly with high-performance, aging- and corrosion-resistant options. 3. Roof deformation: If the car is involved in a collision, the body may deform. If the repair is not done properly, the sealing may not be restored, resulting in leaks. During the repair of accident-damaged cars, it is essential to strictly adhere to the original vehicle standards to prevent mismatched parts and potential leakage issues.
