Why Choose GUOMAT

DAF Truck Cab Air Spring
DAF truck cab air spring system is one of the core components of its suspension system, mainly used to improve driving comfort, reduce shock and noise, and protect the cab structure.

1. Structure and composition
DAF truck cab air springs are usually composed of the following key components:
Airbag (air spring body): Made of multiple layers of rubber and cord layers, filled with compressed air to provide elastic support.
Height control valve: Automatically adjust the air pressure in the airbag according to the load of the cab and the vibration of the road surface to maintain the height stability of the cab.
Air compressor: Provides compressed air to the system (some models share the air source with the vehicle pneumatic system).
Damper (shock absorber): Cooperates with air springs to suppress high-frequency vibrations.
Air pipes and joints: Connect various components to ensure air tightness.

2. Working principle
Dynamic adjustment: The height control valve monitors the displacement of the cab in real time. When the bumpy road causes the cab to sink, the valve inflates to increase the airbag pressure; otherwise, the exhaust reduces the pressure to maintain horizontal stability.
Shock absorption function: The flexible characteristics of the air spring can absorb road impact and reduce the vibration transmitted to the cab.

Load adaptability: Under different loads or road conditions, the system automatically adjusts the stiffness (the higher the air pressure, the greater the stiffness).

3. Technical advantages
Comfort: Compared with traditional leaf springs, air springs can significantly reduce high-frequency vibrations by more than 80%, improving long-distance driving comfort.

Durability: Rubber airbags have strong fatigue resistance and a service life of more than 100,000 kilometers (depending on the working conditions).

Lightweight: Lighter than metal springs, it helps to reduce the weight of the vehicle.

Height adjustable: Convenient for docking with the chassis or adjusting the height of the cab during maintenance.

4. Common faults and diagnosis
Airbag leakage:

Symptoms: The cab is tilted or frequently refilled.

Causes: Rubber aging and cracking, joint seal failure, foreign body puncture.

Detection: Spray soapy water to find bubbles, or listen for leaks.

Height control valve failure:

Symptoms: The cab cannot remain level or responds slowly.

Cause: Valve body mechanical jam, sensor failure.

Insufficient system air pressure:

Symptoms: Shock absorption effect decreases, compressor starts frequently.

Cause: Air compressor failure, pipe blockage or dryer failure.

GUOMAT Factory gate：

Established in 2008, Our company covers 20,000㎡ and is located in Taihe Town Baiyun District. With the rapid development of our company, we are equipped with modernized workshop and advanced rubber air springs equipments now. We are the first company who started air spring business and has become one of the largest air spring manufacturing bases in China.

In 2017, we launched a collaboration with High Tech of US customers to customize the products of our customers and the logo of our customers. Every year, there are about 10,000 orders. In continuous cooperation, the products meet the international inspection standard ISO/TS16949:2009, and the customers are very satisfied with the products produced. This is our high recognition from American customers and also gives us Great motivation.

In 2018, we started cooperation with German GmbH, mainly industrial air springs, which are suitable for industrial equipment. We have successfully developed and produced the natural air-seal of the skin to reach the 700mm flanged air spring, the customer's annual demand is a few hundred.

With the development of business and demand for customers, our company introduced business with TomLog Corporation in 2010, our strategic cooperative partner in Taiwan. Then we developed air compressor program and air spring related business, in 2015, America Goodyear Corporation met with the transfer of shares in the North American plant, our company was granted with sale agent for air springs in China, providing more choice for our customers. Our company adopts the most advanced domestic air spring processing equipment and international production technology. Combined with unique production process, our company strictly execute international standards for production and spare no efforts to create the world-class products. We will endeavor to make air spring widely used at home and abroad, and let more and more customers to enjoy the best damping effect.
