Setting Sail Today! SINO CHOICE Embarking on a New International Journey with Core Components from Sinotruk and Shaanxi Automobile
In the vast ocean of international trade, every shipment carries the hopes and commitments of enterprises. December 3, 2025, marks a momentous day for SINO CHOICE. After days of meticulous preparation, a shipment brimming with core components for Sinotruk and Shaanxi Automobile stands ready to embark on its extraordinary journey across borders, delivering premium Chinese automotive solutions to global customers.
Core Components, Exceptional Quality
These shipped components represent the “heart and backbone” of Sinotruk and Shacman vehicles. Each part underwent rigorous selection and testing to ensure superior quality.
Brake System Components: The Solid Foundation for Safe Driving
Brake Valve Assembly and Master Brake Valve
The brake valve assembly and master brake valve serve as the “command center” of the vehicle's braking system. They precisely regulate brake pressure, transmitting the appropriate force to each brake component according to the driver's input. This ensures smooth, rapid deceleration and stopping during braking. Their intricate internal structure and reliable sealing design guarantee stable operation under harsh conditions, forming the first line of defense for driving safety.
Four-Circuit Protection Valve
The Four-Circuit Protection Valve acts as the “safety guardian” of the braking system. It divides the braking system into four independent circuits. Should one circuit leak or fail, the others remain operational, ensuring at least two wheels retain braking capability. This significantly enhances the system's reliability and safety, effectively preventing brake failure risks caused by single-circuit malfunctions.
Relay Valve
The primary function of the relay valve is to reduce brake response time and improve braking efficiency. During braking, it rapidly transmits brake pressure to the brake chambers, enabling brake shoes to quickly engage with brake drums for swift deceleration. For heavy-duty trucks in particular, the relay valve significantly improves braking performance, reduces stopping distances, and safeguards braking safety during high-speed operation and heavy-load conditions.
Drier Assembly
The drier assembly acts as the “air purifier” within the braking system. It filters and dries moisture, impurities, and oil contaminants from compressed air, preventing these harmful substances from entering the braking system. This protects brake components from rust, corrosion, and wear, extending the system's service life. Additionally, the dryer assembly regulates brake system air pressure, maintaining it within an optimal range to ensure reliable operation.
Double H Valve Assembly and Air Circuit Reversing Valve
The dual H-valve assembly and air circuit reversing valve primarily control trailer braking. The dual H-valve precisely regulates trailer brake pressure based on the tractor's brake signal, enabling synchronized braking between tractor and trailer for enhanced coordination. The air circuit reversing valve alters airflow direction to accommodate varying braking conditions, ensuring flexibility and reliability in the trailer braking system.
Air Filter Pressure Regulator
The air filter pressure regulator performs dual functions of air filtration and pressure regulation. It filters dust and impurities from air entering the braking system, ensuring air cleanliness. Simultaneously, it adjusts air pressure to an appropriate range, providing a stable air supply to the braking system and ensuring proper operation of braking components.
Trailer Control Valve
The trailer control valve is a core component of the trailer braking system. It receives braking signals from the tractor and controls the trailer's brake chambers to execute braking actions. Through precise control, the valve ensures the trailer brakes in synchronization with the tractor during braking, preventing dangerous situations like trailer sway and enhancing overall vehicle safety.
Brake Chamber
The brake chamber is a device that converts pneumatic energy into mechanical energy. When brake pressure enters the chamber, it drives the piston to move. Through the pushrod, force is transmitted to the brake shoes, causing them to contact the brake drum and generate braking force. The performance of the brake chamber directly impacts braking effectiveness. A high-quality brake chamber provides stable and reliable braking force, ensuring vehicle braking safety.
Handbrake Valve
The handbrake valve is the vehicle's manual braking mechanism. When parking or in emergencies, the driver operates the handbrake valve to activate the braking system, preventing vehicle slippage or loss of control. Its design prioritizes ease of operation and reliability, ensuring effortless braking in all scenarios.
