The running system is divided into four main parts: the axle, wheels, frame, and suspension. Here are the details about the axle part: 1. Definition: The axle (also called the wheel axle) is connected to the frame (or the load-bearing body) through the suspension, with wheels installed at both ends. 2. Function: Its role is to transmit forces in all directions between the frame (or load-bearing body) and the wheels. 3. Types: The axle can be a solid type, resembling a large dumbbell, with both ends supporting the body through the suspension system, so solid axles are usually paired with non-independent suspension; the axle can also be a split type, like two umbrellas inserted on both sides of the body, each supporting the body through the suspension system, so split axles are paired with independent suspension. 4. Classification: Depending on the driving method, axles are also divided into four types: steering axle, drive axle, steering drive axle, and support axle.

The four key components of the automotive running gear include the frame, axles, wheels, and suspension system. The frame acts like the vehicle's skeleton, supporting the entire structure and ensuring stable driving without wobbling. The axles connect the wheels to the frame, transmitting power and coordinating wheel movement, especially during turns. The wheels, which include tires, directly contact the road surface, providing traction and rolling capability—pay extra attention to tire conditions during winter or rainy/snowy weather. The suspension system absorbs road impacts, reducing bumps when driving over speed bumps or rough roads, making the ride smoother and more comfortable. If you notice excessive shaking or unstable steering while driving, it might indicate issues with the suspension or tires. Regular maintenance checks at a repair shop are recommended to prevent misalignment or excessive wear, ensuring safety.

When the rear car's image occupies one-third of the right rearview mirror, the distance is about 12 meters; 5. When the left rearview mirror shows the middle of the rear wheel cover (rear door handle, body horizontal line, or the reflection of the rearview mirror's bottom line) relative to the ground, that is the position of the rear of the car; 6. When the upper edge of the rear headlight is seen in the interior rearview mirror, the distance between the rear trunk and the rear car is about three and a half meters; 7. When the junction of the rear car's engine hood and the front windshield is seen in the interior rearview mirror, the distance between the rear trunk and the rear car is one meter; 8.

Is the BMW X5 Plug-in Hybrid Exempt from Purchase Tax?

Plug-in hybrids are still exempt from purchase tax. Plug-in hybrid electric vehicles (PHEVs) can enjoy benefits such as purchase tax exemption, green license plates, and government subsidies. The differences between plug-in hybrid electric vehicles and conventional hybrid vehicles are: 1. Conventional hybrid vehicles: They have very small battery capacity, only supplying/recovering energy during start-stop and acceleration/deceleration. They cannot be charged externally and cannot drive long distances in pure electric mode. 2. Plug-in hybrid electric vehicles: They have relatively larger batteries, can be charged externally, and can drive in pure electric mode. When the battery is depleted, they switch to hybrid mode (mainly powered by the internal combustion engine) while charging the battery when appropriate.
