Main Applications
These components are mainly used in suspension systems of commercial vehicles (trucks and buses), and their resistance can be adjusted by changing the air pressure. They have functions that balance both softness and hardness as suspension systems, to achieve stability and riding comfort.
Features
Reduces the burdens placed on cargo, drivers, and passengers
Facilitates passenger boarding/disembarking and cargo receiving operations
Maintains a consistent vehicle height by adjusting the air pressure
Assists starting when on a slope, and raises driving force when traveling on two wheels
Reducing the number of parts can contribute to weight reduction
Basic Product InformationRequest for documentation
We have an extensive lineup including products for small to large trucks and buses, so products can be selected to meet customer needs. We have results of use for effective diameters from 120 mm to 270 mm, and we can also provide proposals for even smaller or larger sizes.
| Product Lineup | Effective Diameter | Features |
|---|---|---|
| Diaphragm type |
Maximum diameter: 270 mm Minimum diameter: 120 mm |
■ Shape which is mainly used in air springs for trucks and buses ■ Simple shape with low cost ■ Large stroke volume can be ensured on the elongation and compression sides ■ High degree of freedom for tuning spring properties |
| Bellows type |
Maximum diameter: 230 mm Minimum diameter: 200 mm |
■ Excellent durability (compared to diaphragm type) ■ Installation height can be set to be low |
Application Proposals
Can achieve smaller sizes and lighter weights than leaf suspension.
■ Improvement of load factor
Provides high riding comfort (vibration absorption) and can maintain balance while adjusting the tilt of the vehicle.
Results of Use
Estimated market share in Japan of more than 60%.
We have results of use as official products by various truck and bus manufacturers in Japan.
Note that the above are only selected examples, and we are able to produce air springs to meet customer needs.
We have many other results of use as well, so please feel free to inquire with us for more information.
Nitta’s Technology
We have results of use for effective diameters from 120 mm to 270 mm, and we can also provide proposals for even smaller or larger sizes.
We will design products in accordance with customer requests.
(blending technology)
We have a diverse lineup that allows blending to be performed according to the application.
(automation)
We have introduced semi-automatic molding machines and succeeded in reducing the number of required personnel.
(size)
Replacement with vulcanization types enables vulcanization from small to large diameters.
The number of parts can be reduced by caulking metal fittings (plates) and rubber components (diaphragms).
In addition to meeting customer requirements, we provide product assurance based on our own strict, independent standards and mechanisms.
Testing machines can reduce the number of defects by performing analysis from various standpoints.
