It is even permissible for all four wheel rims to have different styles. 2. Roof racks and side step boards can be installed: This new regulation mainly applies to SUV and MPV models. The height of the installed roof rack must be within 300 millimeters, and the width of the side step board must not exceed 5 centimeters beyond the side of the vehicle body. 3. Vehicle body color can be changed: The vehicle body color can be altered through painting or wrapping, but the changes must be registered with the vehicle management office within ten days. It is important to note that colors similar to those used on police cars, fire trucks, and other official vehicles are not allowed. 4.

Does a larger motor pulley rotate faster or a smaller one?

If we're only considering the motor's rotational speed, the size of the motor pulley (large or small) doesn't affect it—the speed remains the same. However, when it comes to the driven mechanical equipment, a larger motor pulley will result in faster equipment rotation, while a smaller motor pulley will lead to slower equipment rotation. Below are some maintenance methods for electric motors: 1. Keep the operating environment dry: The motor surface should be kept clean, and the air intake should not be obstructed by dust, fibers, etc. 2. Identify faults: If the motor's thermal protection repeatedly triggers, determine whether the fault originates from the motor itself, overloading, or the protection device's setting being too low. Only after resolving the issue should the motor be put back into operation. 3. Ensure good lubrication during operation: Generally, after about 5,000 hours of operation, the motor's grease should be replenished or replaced. If bearing overheating or grease deterioration is observed during operation, replace the grease promptly. When replacing the grease, remove the old lubricant and clean the bearing and bearing cover's oil groove with gasoline.

Comparison: Based on the 9AT, the 9HAT adds a high-power P2 hybrid motor and a C0 clutch structure for disconnecting or connecting the transmission with the engine power, enabling pure electric or hybrid driving modes for the vehicle. 2. Introduction: The transmission is a mechanism used to change the speed and torque from the engine. It can fixedly or stepwise change the transmission ratio between the output shaft and the input shaft, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, and some vehicles also have a power take-off mechanism. Most transmission mechanisms use ordinary gear transmission, while some use planetary gear transmission. Ordinary gear transmission mechanisms generally use sliding gears and synchronizers.
