Introduction to Knowledge about Truck Wearable Parts

In the daily operation and maintenance of trucks, a correct understanding and reasonable maintenance of wearable parts are crucial for ensuring the performance, safty and operational efficiency of trucks. The following will provide a detailed description of common wearable parts of trucks.

Oil Filter 

The oil filter is a key component in the lubrication system of a truck's engine. Its main function is to filter out impurities such as metal shavings and dust particles from the engine lubricating oil, ensuring the cleanliness of the lubricating oil and maintaining the normal lubrication and operation of the engine. When changing the oil, the oil filter must be replaced simultaneously. This is because dirty oil, if circulated again through an un-replaced filter, will cause wear and damage to the internal components of the engine, seriously affecting the service life and performance of the engine.

Air Filter

The air filter plays an important role in the intake system of a truck. It is responsible for filtering the air entering the combustion chamber of the engine, preventing dust, impurities and foreign objects from entering the engine and protecting the precision components such as the cylinder body and piston of the engine. Generally, it is recommended to replace the air filter of a truck after driving 10,000 - 20,000 kilometers. The specific replacement time should be adjusted according to the actual usage environment and working conditions of the vehicle. For example, for vehicles driving in environments with a lot of sand and dust, the replacement cycle of the air filter should be shortened accordingly.

Engine Mounting Rubber 

As an elastic support component, engine mounting rubber is used to fix the engine. It can absorb and buffer the vibration of the engine during operation, preventing the vibration from being directly transmitted to the body, thus ensuring the driving comfort and stability of the vehicle. With the increase of service time, the engine mounting rubber will age, resulting in a decrease in its buffering performance. At this time, abnormal noises may occur in the engine area of the vehicle. Once it is found that the engine mounting rubber is aged or damaged, it should be replaced in time.

Spark Plug 

The spark plug is an important component in the engine ignition system. Its main function is to ignite the mixture in the combustion chamber of the engine. The performance of the spark plug directly affects the starting, combustion efficiency and power output of the engine. Generally, the replacement cycle of the spark plug is about 30,000 - 60,000 kilometers. Different models and engine working conditions may lead to differences in the service life of spark plugs. Therefore, during vehicle maintenance, spark plugs should be replaced on time according to the recommendations of the vehicle manufacturer and the actual usage conditions of the vehicle.

Half Shaft Dust Cover 

The half shaft dust cover is located at the half shaft of the vehicle. Its main function is to seal the half shaft ball joint, prevent lubricating oil from leaking, and prevent external moisture, dust and impurities from entering the half shaft system. Once the half shaft dust cover ages, cracks or damages, lubricating oil may leak, causing rapid wear of the half shaft and affecting the normal driving of the vehicle. Therefore, during daily vehicle inspections, attention should be paid to the condition of the half shaft dust cover, and it should be replaced in time if damaged.

Ball Joint of Tie Rod 

The ball joint of the tie rod connects the steering gear and the steering arm and is responsible for transmitting the force and torque during steering to ensure the steering performance of the vehicle. During long-term driving, the ball joint of the tie rod may become loose or produce abnormal noises due to wear and aging. The loosening of the ball joint of the tie rod will affect the handling and safety of the vehicle. Therefore, during daily inspections, if the ball joint of the tie rod is found to be loose or making abnormal noises, it should be replaced in time.

Shock Absorber Buffer Rubber 

The shock absorber buffer rubber is installed inside the shock absorber and plays a role in buffering the vibration caused by the weight of the vehicle body. With the increase of service time and mileage, the shock absorber buffer rubber may age, crack or deform. When the shock absorber buffer rubber is damaged, the shock absorption effect will be reduced, affecting the driving comfort and stability of the vehicle. Therefore, once the above problems are found in the shock absorber buffer rubber, it should be replaced immediately.

Shock Absorber 

The shock absorber is an important component of the vehicle suspension system. Its main function is to absorb and buffer the vibration caused by the uneven road surface during vehicle driving, ensuring the driving quality and comfort of the vehicle. Generally speaking, the replacement cycle of the shock absorber is about 80,000 kilometers or when the vehicle has obvious abnormal noises, deformations and other abnormal conditions. The top rubber of the shock absorber is connected to the vehicle body. When the top rubber of the shock absorber ages or makes abnormal noises, it also needs to be inspected and considered for replacement.

Tire 

The tire is the part of the truck that directly contacts the road surface, and its performance is directly related to the safety and handling of the vehicle. Generally speaking, the replacement cycle of tires is about 50,000 - 100,000 kilometers, but the actual replacement cycle should be adjusted according to the usage environment and working conditions of the vehicle. For example, for vehicles with poor road conditions and frequent overloading, the wear rate of tires will increase and the replacement cycle will be shortened accordingly.

Battery 

The battery provides electrical energy for the electrical system of the truck. Starting the engine and supplying power to the electrical equipment of the vehicle all require the support of the battery. For ordinary non-maintenance-free batteries, the replacement cycle is generally about 60,000 kilometers or 2 - 3 years; for maintenance-free batteries, although frequent maintenance is not required, the battery power should be checked regularly. Generally speaking, when the battery power of the maintenance-free battery is insufficient or other abnormal conditions occur, it should be replaced or repaired in time.

Engine Timing Belt 

The engine timing belt is an important component of the internal transmission system of the engine. Its function is to ensure that each component of the engine works at the correct time. For rubber timing belts, it is recommended to inspect or replace them after 4 years or 60,000 kilometers of driving; for timing chains, they do not need to be replaced according to the above time, but their wear conditions also need to be checked regularly during long-term use.

Air Conditioner Filter and Other Small Wearable Parts 

The air conditioner filter is used to filter the air in the vehicle and keep the air in the vehicle fresh. Generally speaking, the air conditioner filter should be replaced once a year before the vehicle starts using the air conditioner, and it is best to replace it in time after the rainy season to prevent bacteria from breeding and affecting the health of the passengers. In addition, other small wearable parts of the vehicle, such as wiper blades, also have their own service life and maintenance requirements. It is generally recommended to replace them once a year to ensure their cleaning effect.

Understanding the wearable parts of trucks and related knowledge is of great significance for the correct use, maintenance and repair of trucks. It is hoped that the above introduction can provide useful references for truck users and operators, helping everyone better maintain the performance of trucks and ensure the safe operation of vehicles.
