What does the lock mode mean in a four-wheel drive vehicle?
1 Answers
Four-wheel drive lock mode refers to the locking of all four wheels in a four-wheel drive vehicle. Here is some relevant information: 1. All-wheel drive, also known as four-wheel drive, means that both the front and rear wheels of the vehicle have power. It is generally represented by 4x4 or 4WD. If you see these markings on a vehicle, it indicates that the vehicle has four-wheel drive capability. 2. All-wheel drive can be divided into two types: one is full-time all-wheel drive, which means the vehicle is always in all-wheel drive mode. The other is part-time all-wheel drive, which can cut off the power to a specific axle to reduce fuel consumption and wear, and only engage all-wheel drive when needed. 3. AWD can achieve optimal handling at all times. Compared to RWD and FWD, AWD distributes less traction to each driving wheel, so there is less likelihood of traction exceeding the friction between the tires and the ground, meaning the driving wheels are less likely to slip. Clearly, four-wheel drive provides a higher level of traction and handling because the traction is shared by four wheels instead of two. It can handle higher cornering limits, especially on rough or slippery surfaces, which is why AWD has been primarily used in WRC racing since Audi introduced it in the 1980s. 4. Full-time AWD cars tend to have neutral steering tendencies, thanks to the traction being shared by all four wheels. In fact, this is also related to weight distribution, and typically, full-time AWD cars have a 50:50 weight distribution between the front and rear, making it difficult to experience oversteer.
