Is a Car Torque Converter a Clutch?

1 Answers

07/25/25 10:26am

A torque converter is a hydraulic component composed of a pump impeller, turbine, and guide wheel. It is installed between the engine and the transmission, using hydraulic oil as the working medium to perform functions such as torque transmission, torque conversion, speed change, and clutch engagement. A clutch, also known as a dry friction clutch, is a component that cuts off and transmits power between the engine and the vehicle's drivetrain. Therefore, a car torque converter is not a clutch. Working principles of clutches and torque converters: 1. Clutch: During vehicle operation, the driver can depress or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and the transmission, thereby cutting off or transmitting the engine's power input to the transmission. 2. Torque Converter: In a hydraulic coupling, the flow of oil reverses. The pump impeller of the hydraulic coupling is rigidly connected to the engine crankshaft. When rotating, centrifugal force causes the ATF (Automatic Transmission Fluid) to be thrown outward, impacting the turbine blades and causing the turbine to rotate passively. The fluid returning from the turbine then impacts the pump impeller, hindering its rotation.

What Causes a Thud Sound from the Chassis When Starting the Car?

Car starting with a thud sound from the chassis is due to the aging of certain components in the car's chassis. After a period of use, the suspension system ages rapidly. Some supporting parts gradually lose their original function, causing the chassis to make a creaking sound when starting the car. Below is an introduction to car maintenance: 1. Exterior Inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect for body damage, tilting, oil or water leaks, etc. 2. Engine and Various Fluids: Check the fastening of engine components and inspect for oil or water leaks at engine joints. Adjust belt tension and inspect the fastening of pipelines and wiring. Top up engine oil, coolant, and battery electrolyte as needed. 3. Tires: Check tire wear and clean the trunk. Replace tires when they approach the wear indicators. Inspect for bulges, abnormal wear, aging cracks, or hard damage. 4. Cleaning and Lubrication: Clean oil stains from the engine compartment cover, door, and trunk hinge mechanisms, and lubricate them. Antifreeze typically has a service life of 2 years and should be replaced during maintenance, along with a thorough cleaning of the cooling system. Due to the hygroscopic nature of the brake system, brake fluid should be replaced every two years.

How to Deal with Squeaking Sounds When Opening Car Doors?

Solutions for abnormal noises when opening and closing car doors: 1. Check for aging: Inspect whether the door seals are aged, and it is recommended to replace the seals; 2. Check for foreign objects: Examine the door gaps for any foreign objects, which need to be cleaned out; 3. Poorly fixed components: Abnormal noises caused by poorly fixed components between the door parts can be resolved by tightening the screws; 4. Insufficient body stiffness: Friction between steel plates due to insufficient body stiffness or welding detachment, and it is recommended to have it repaired at a maintenance shop. Design requirements for car doors: 1. Ensure convenience for passengers getting on and off, with the opening angle controlled at around 65 to 70 degrees; 2. No positional interference with other parts during the opening process; 3. Reliable locking when the door is closed, preventing it from opening on its own while driving; 4. Good sealing performance; 5. Large light-transmitting area to meet lateral visibility requirements; 6. Sufficient strength and stiffness to ensure reliable door operation, reduce door vibrations, enhance vehicle lateral collision safety, and prevent door sagging.

How to Quickly Remove Odors Inside the Car?

Here are methods to quickly eliminate odors inside the car: 1. Ventilation and Sunlight Exposure: The first step is to ventilate the car. On sunny days, park the car in a dry, well-ventilated area to air it out. This method provides immediate results in removing odors. Avoid parking in damp areas for extended periods, as it can lead to musty smells and negatively impact the car's lifespan. 2. Orange or Grapefruit Peels: Placing orange or grapefruit peels inside the car can help eliminate odors and freshen the air. These fruit peels have strong odor-absorbing properties, not only releasing a pleasant fragrance but also effectively neutralizing unpleasant smells, creating a refreshing atmosphere. 3. Activated Charcoal Bags: Activated charcoal is highly effective in absorbing odors, including formaldehyde and other unpleasant smells. Placing activated charcoal bags inside the car is an excellent way to remove odors. 4. Vinegar: Acetic acid in vinegar can neutralize formaldehyde and other odors inside the car, helping to eliminate harmful substances. When the car is not in use, mix vinegar with water in a spray bottle. Spray it on seats and door interiors, then wipe with a cloth.

Why Can't the Sunroof of BMW 5 Series Open?

There are many reasons why the sunroof of a BMW 5 Series car cannot open, with the most common being the following four: 1. Sunroof circuit malfunction; 2. Damage to the sunroof drive motor; 3. Severe lack of lubrication in the sunroof track, causing the sunroof seal to stick to the car body; 4. Presence of foreign objects in the sunroof slot. Here is some related information about the BMW 5 Series: 1. Vehicle positioning: The BMW 5 Series is a mid-size luxury sedan under BMW, and it is a C-class sedan. 2. Power aspects: The domestically produced BMW 5 Series uses two engines: one is a low-power version 2.0-liter turbocharged engine, and the other is a high-power version 2.0-liter turbocharged engine. 3. Suspension type: The BMW 5 Series uses a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear.

Can a Mainland Driver's License Be Used in Taiwan?

Mainland driver's licenses cannot be used in Taiwan. Here are the specific reasons: 1. Mutual Non-Recognition of Each Other's Driver's Licenses: Primarily because Mainland China is not a signatory to the Geneva Convention, and both sides do not recognize each other's driver's licenses. Therefore, a Mainland driver's license is not valid in Taiwan. Many so-called international driver's permits are merely translations of the Mainland China driver's license, and Taiwan does not recognize these translated versions either. 2. Taiwan's Regulations: According to current regulations in Taiwan, even if a Mainland driver's license is converted into a so-called international driver's permit, driving with it is considered unlicensed and subject to fines. In cases of drunk driving or accidents, not only will there be no insurance compensation, but the driver will also face legal liabilities. This could even affect the emergency contact's future entry to Taiwan. The only way to rent or drive a car in Taiwan is to first obtain a driver's license from a third region (such as Hong Kong, the United States, or many other countries and regions worldwide) and then obtain an international driver's permit issued by that third region (e.g., the United States).

What are the methods to remove ice from car windows after they freeze?

Here are the solutions for dealing with frozen car windows in winter: 1. Turning on the heater: There are two types of air conditioning systems, manual and automatic: For manual air conditioning, first turn the temperature knob to the lowest position in the red zone and set the heater to the hottest setting. Then, rotate the air distribution mode button to the windshield defrost position. Next, turn off the recirculation button and set the fan speed to 4 or higher—the higher the speed, the faster the ice will melt. For automatic air conditioning, simply select the front window defrost button on the center console, and the system will automatically adjust to the highest temperature and maximum fan speed. 2. Ice removal tools: If you live in a particularly cold area where the windshield freezes every morning, consider purchasing ice removal tools such as an ice scraper. These tools can be quicker and more effective. 3. De-icer: Car window de-icer is a specialized antifreeze concentrate designed to thaw frozen windows and wipers without damaging the car's surface. It can effectively prevent window freezing even without using the car's heater. If ice has already formed, simply spray the de-icer onto the inner surface of the car window and wipe it clean.
