This article introduces the truck steering system, which is the core of precise control. It consists of a steering control mechanism, a steering gear, and a steering transmission mechanism, and also includes a power assist system, with types such as mechanical hydraulic, electro-hydraulic, and electric power steering. It also mentions special technologies like rear-wheel steering and intelligent auxiliary steering, as well as maintenance points such as checking steering fluid and component connections, and looks forward to its future trends of electrification and intelligence.

This article briefly introduces the truck drive shaft, which is the core link for power transmission. It is composed of a shaft tube, a telescopic sleeve and a universal joint. It expounds its working principle of transmitting engine power to the drive axle through the gearbox, analyzes common faults such as looseness, bolt falling off and vehicle shaking as well as their causes, and also puts forward maintenance points such as regular lubrication, component inspection and reasonable driving, emphasizing that attention should be paid to its maintenance to ensure the operation of the truck.

This article focuses on truck starters, introducing them as the core component of the starting system, which can convert the electrical energy of the storage battery into mechanical energy to drive the engine to start. It expounds on its working principle based on DC motors, its structure composed of DC motors, transmission mechanisms and electromagnetic switches, its classification according to the form of DC motors, control devices and the meshing mode of transmission mechanisms, and also lists common faults such as starters not working and idling as well as their solutions. It emphasizes the importance of understanding these for ensuring the operation of trucks.

This article focuses on the safe driving of trucks in rainy weather, pointing out that driving in rainy weather is highly risky. It is necessary to control the speed, maintain a safe distance from the vehicle ahead, and check the braking system and tires, etc. It emphasizes the correct use of wipers: check their condition before driving, adjust the speed according to the rainfall, clean them regularly and add appropriate wiper fluid to ensure clear visibility and reduce the risk of accidents.
