According to the 'Regulations on the Management of Over-Limit Transport Vehicles Driving on Highways', the weight limit for a three-axle truck on the highway is 25 tons, and for a three-axle articulated vehicle, it is 27 tons. The following are the types of three-axle vehicles: 1. Three-axle truck: A three-axle truck has three axles and multiple drive shafts. The drive shaft is the component that transmits the driving force from the engine to the driving wheels. Here, 'axle' refers to the connecting bridge between the two wheels, and the three-axle configuration is suitable for FR (front-engine, rear-wheel-drive) vehicles. Each articulated vehicle typically consists of a tractor unit towing different trailers. 2. Three-axle articulated vehicle: Three-axle articulated vehicles played a significant role in transporting military supplies during wartime.

What are the common faults of the parking brake?

The common faults of the parking brake include: ineffective braking, brake failure, deviation, and dragging. The causes of these faults are: 1. Insufficient brake oil pressure; 2. Air in the brake system; 3. Excessive free travel of the brake pedal or excessive brake clearance; 4. Wear or damage to the brake master cylinder, wheel cylinder piston, wheel cylinder pipe, or aging and damage of the rubber cup. The method of using the parking brake is: during operation, the four fingers of the right hand are brought together, the thumb is placed forward, the right hand is lifted forcefully to tighten the control lever, and at the same time, the brake indicator light on the dashboard lights up. The parking brake refers to the manual brake installed on motor vehicles, commonly known as the handbrake, which is used to stabilize the vehicle after it has come to a stop, preventing accidents caused by the vehicle rolling on sloping roads.

What Causes Tire Noise?

Tire noise can be caused by: 1. Small stones stuck in the brake disc, causing friction noise during driving; 2. Abnormal wear of the tire bearing due to lack of lubricating oil; 3. The main material of the brake pads being heavy metal, which may have metal hard spots; 4. Deformation of the brake pad shield, causing it to rub against the rotating tire and produce noise. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and passability; 3. To prevent severe vibration and early damage to automotive components.

What are the precautions for sleeping in a car with the air conditioning on?

Precautions for sleeping in a car with the air conditioning on are: 1. Park the car in an open, spacious, and well-ventilated area, and adjust the direction of the air vents; 2. Switch from internal circulation to external circulation; 3. Leave a 2 to 3 cm gap in the window for air circulation; 4. Avoid sleeping in the car for too long. The function of a car air conditioning system is to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to a comfortable state, providing a pleasant environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and ensuring safe driving as an important ventilation device.
