What is Automotive Traction?

1 Answers

Automotive traction refers to the force generated by the friction between the wheels and the ground that propels the vehicle forward, also known as the driving force. Functions of Automotive Traction: The role of automotive traction is to prevent the spinning of drive wheels when driving on slippery surfaces like snow or wet roads, as well as to avoid wheel slippage during vehicle startup and acceleration. It involves brake torque control and engine torque control. Working Principle of Automotive Traction: The system uses a computer to monitor the speed of all four wheels and the steering angle of the steering wheel. When acceleration is detected and the speed difference between the drive wheels and non-drive wheels is too large, the computer immediately determines that the driving force is excessive and sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the drive wheels.

Can a tire pressure of 220 run on the highway?

A tire pressure of 220 can run on the highway, but it is not recommended. Generally, the tire pressure value within the range of 2.2 to 2.5 BAR is safe. In summer, when temperatures are high, the tire pressure, which is within the normal range when the car starts, may actually rise. Therefore, in summer, it is advisable to maintain a slightly lower tire pressure within the normal range, while in autumn and winter, it can be controlled at 2.5 BAR. Tires are often used under complex and demanding conditions. During driving, they endure various deformations, loads, forces, and the effects of high and low temperatures. Therefore, they must have relatively high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have relatively high wear resistance and flex resistance, as well as relatively low rolling resistance and heat generation.

Can I buy a bus ticket without an ID card?

No, you cannot buy a bus ticket without an ID card. According to regulations, operators of inter-provincial and inter-city passenger transport routes, or ticket-selling units entrusted by them, as well as departure, destination, and intermediate stop stations, must implement real-name ticket sales and identity verification. For routes under real-name management, passengers must provide the original copy of a valid ID card when purchasing tickets, and the ticket seller must record the passenger's identity information on the ticket. Passengers must carry and present valid identification documents when purchasing tickets and boarding the bus, with one valid document required to purchase one ticket (the person, document, and ticket must match). Passengers who purchase tickets online or by phone must carry their ID cards for verification. Additionally, when handling procedures such as ticket changes or refunds, passengers must present the original valid document used at the time of purchase.

Why is it said that the transmission fluid of the Regal should never be changed?

The reason why the transmission fluid of the Regal should never be changed: The transmission fluid of the Regal can be changed, and replacing it when a fault occurs is a good solution. The phrase 'should never be changed' refers to not replacing it casually, as many transmission fluids cannot be mixed. The function of transmission fluid is to lubricate the gears, and generally, as long as there is no leakage, it does not need to be replaced. The Regal is one of Buick's successful strategic models, featuring the brand's new sculptural aesthetic design language. The larger-sized winged chrome grille extends horizontally from the centerline, with the shield-shaped upper grille complementing the trapezoidal lower grille that flares outward. Combined with the air curtain design on both sides, the front face presents a wide-body, low-slung sporty presence.
