What is the Function of a Car Steering Wheel?

The function of a car steering wheel is to convert force into torque and transmit it to the steering shaft. The steering wheel, also known as the driving wheel, is a wheel-shaped device used to control the direction of vehicles such as cars, construction machinery, and agricultural vehicles. The hub, rim, and spokes of the steering wheel are typically made with an inner core of steel, aluminum alloy, magnesium alloy, or carbon fiber. The steering wheel is usually connected to the steering shaft via splines. As a general rule, avoid turning the steering wheel forcefully while the vehicle is stationary, commonly referred to as 'locking' the steering. When the wheels are not rolling, the friction between the tires and the ground is significantly higher, placing greater stress on the steering mechanism. Turning the steering wheel while stationary not only risks damaging the steering mechanism but can also cause severe tire wear.

What is a High-Speed ETC Card?

An ETC vehicle refers to a vehicle equipped with an ETC on-board unit. ETC stands for Electronic Toll Collection in Chinese, which is currently the most advanced toll collection method for roads and bridges worldwide. It utilizes dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. ETC achieves the purpose of allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees by using dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. This is done through computer networking technology for backend settlement with banks. The fully automatic electronic toll collection system (ETC) is one of the service functions of the intelligent transportation system. It is particularly suitable for use on highways or in busy bridge and tunnel environments. Currently, there are dedicated ETC toll lanes at highway toll stations. As long as the vehicle owner installs a sensor card on the windshield and prepays the fees, there is no need for manual payment or stopping at the toll station. The highway toll will be automatically deducted from the card, enabling automatic toll collection. This system takes less than two seconds per vehicle for toll collection, and its toll lane capacity is 5 to 10 times that of manual toll lanes. The use of a fully automatic electronic toll collection system can make highway toll management paperless and cashless, fundamentally eliminating the loss of toll revenue and solving financial management chaos in highway toll collection. Additionally, implementing a fully automatic electronic toll collection system can save on infrastructure and management costs. Documents required to apply for ETC: The vehicle owner's valid original ID card, the original and a copy of the vehicle registration certificate (the page with the most recent annual inspection stamp must be provided). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying through major bank branches, a corresponding bank debit or credit card must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. ETC deduction principle: There will be one or more ETC lanes on the highway. Through dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, backend settlement is processed with banks using computer networking technology. This allows vehicles to pass through highway or bridge toll stations without stopping to pay fees, all based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, reducing wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide vehicle owners with comprehensive travel services, meaning more application scenarios will support ETC usage. ETC usage precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of more than 10 meters to prevent automatic sensing and payment for the vehicle in front, in case its ETC device is faulty or nonexistent. The recognition speed for ETC lanes is 20 km/h. If the speed is too fast, the vehicle's device information cannot be read, leading to failed fee deductions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will cause the electronic tag to fail. It can be taken to the bank where the ETC card was issued or to a highway service office for inspection. If the loosening or detachment is not due to human intervention, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also cause fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass through using cash or card payment. Thick car windshields may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

What are the reasons for engine revving without acceleration during normal driving?

Here are the reasons and solutions for engine revving without acceleration during normal driving: 1. Control system or cooling system failure: If there's no issue with the transmission itself, the problem may lie in the control system or cooling system. The vehicle may suddenly experience engine revving during steady driving, but returns to normal when slowing down. This occurs when the transmission abruptly shifts from a high gear to a low gear without timely response. Solution: Reduce speed to allow the vehicle to cool down. 2. Clutch plate failure: Brake clutch pressure leakage causes slipping, which may result from insufficient transmission valve body oil pressure or damaged buffer plates leading to transmission slippage. Solution: Visit a 4S shop or repair shop for fault inspection and repair.
