Air Reservoir Assembly
The air reservoir assembly is a central component of the front air reservoir group. This cylindrical tank stores compressed air produced by the air compressor. The stored air is essential for the proper functioning of the truck’s braking system. The reservoir is constructed from durable materials to withstand high-pressure conditions and environmental stressors.
U Bolt and Air Reservoir Bracket Assembly
The U bolt is used for securing the air reservoir to its mounting bracket. This fastening component ensures that the reservoir remains firmly in place, even under the vibrations and stresses encountered during operation. The air reservoir bracket assembly provides a stable support structure for the reservoir. Together, these components maintain the reservoir’s alignment and stability, contributing to the overall reliability of the air brake system.
Air Intake Valve Assembly and Air Reservoir Support
The air intake valve assembly is crucial for controlling the entry of air into the reservoir. It regulates the flow of air, ensuring that the reservoir is filled to the appropriate pressure levels. The air reservoir support provides additional reinforcement to the bracket assembly, enhancing the structural integrity of the air reservoir setup.

Gasket Rings and Elbow Pipe Joint Assembly
Gasket rings are used in various parts of the assembly to prevent air leaks and ensure a tight seal between components. Multiple gasket rings are strategically placed around the connections to maintain pressure within the system. The elbow pipe joint assembly facilitates changes in the direction of the air flow, connecting different sections of the pipeline while ensuring a secure and leak-proof connection.
Steel Wire Hook and Plastic Sleeve
The steel wire hook is employed to secure various components, including hoses and pipes, to the air reservoir assembly. It provides additional stability and prevents accidental disconnections. The plastic sleeve offers protection to the hoses and wiring from abrasion and environmental damage, prolonging their lifespan and maintaining the system’s efficiency.
Catch Strap of Electric Wire Harness and Strap Assembly
The catch strap of the electric wire harness organizes and secures the electrical wiring connected to the air reservoir system. This prevents wires from tangling or becoming damaged. The strap assembly further secures various components, including the air reservoir, to their respective positions. It ensures that all parts remain correctly aligned and supported throughout the vehicle’s operation.
End Pipe Joint and Reservoir Frame Assembly

The end pipe joint connects the air reservoir to other parts of the air brake system, allowing for seamless air transfer. The reservoir frame assembly provides a rigid framework that supports the entire air reservoir system. This frame helps maintain the correct positioning of the reservoir and associated components, contributing to the overall stability of the system.
Water Drain Valve Assembly
The water drain valve assembly is a critical feature for maintaining the air reservoir’s performance. It allows for the removal of accumulated moisture that can condense within the reservoir. Regular drainage prevents corrosion and ensures that the air system remains free of contaminants that could impair its functionality.
Bolt, Nut, and Screw Plug
Bolts and nuts are used extensively throughout the air reservoir group to secure components in place. These fasteners ensure that all parts of the assembly are tightly connected and remain stable during operation. The screw plug is used to seal various openings in the air reservoir assembly, providing an additional layer of protection against leaks.
Air Reservoir Bracket Assembly
The air reservoir bracket assembly is a key structural element that holds the air reservoir in place. It consists of various brackets and supports designed to accommodate the reservoir’s size and weight. This assembly ensures that the reservoir remains securely mounted, even under the stresses of regular use.
Conclusion
The front air reservoir group of the Dongfeng DFL4251A8-T31R-931-02 series tractor truck is a meticulously designed system comprising multiple components that work together to ensure optimal performance and reliability. From the primary air reservoir assembly to the various supports, brackets, and fittings, each part plays a crucial role in maintaining the efficiency and safety of the air brake system. Understanding the functions and interconnections of these components is essential for effective maintenance and operation, contributing to the overall reliability and longevity of the vehicle.
