Varied air suspension systems are produced such as roll, piston-free, complete, multi-layered, cabinet to be used in tow trucks/ trucks/ buses/ trailers/ semi-trailers within the organization of Aktaş Holding.

We see that while the tow truck/truck air suspension spring was generally used in trucks and trailer trucks with high tonnage (>16t.), its use in the trailer group vehicles and tow trucks with medium tonnage (7.5 - 16t.) has increased presently. We produce the air suspension springs for use of them in varied parts of vehicles such as in front, rear and axle of trailers and in tow truck axle of towing trucks.

Springs covered by plate sheet named metal spring are used in trucks, tow trucks, trailers. In this type of spring, a plate sheet covered on the spring connects the spring with the frame. Connection with the piston is, however, made via a sub-bowl or independent tension sheet vulcanized on the spring for connection with the axle. These products are produced in a cylindrical or conic form.

The bus air suspension springs were derived from the need for improving the driving comfort by absorbing librations, vibrations and sudden shocks in buses caused by structure of roads almost 50 years ago and the air suspension spring is used in almost all buses in Europe. We produce the air suspension springs to meet the requirements for more comfortable driving and more optimum loading on vehicles.

The type of spring generally preferred for buses and light commercial vehicles is the roll springs. The roll springs are the springs having ultra spring sensitiveness. They provide extremely comfortable suspension reaching high strokes without any increase in the operating diameter due to their long product lengths generally. The plates and pistons produced in appropriate diameter and conic form may be easily mounted and demount to/from these products with both connection necks being conic. However, the direction of the conic part with a narrow diameter must be mounted on the piston (axle-lower) and its direction with a wide diameter must be mounted on the plate (frame-upper) in the types produced in a conic form.

There are varied operating pressure intervals, connection heights, operating spaces, operating frequencies and lifting forces for different areas of use.

The air suspension springs in buses both ensures high driving comfort for passengers and enables to keep the vehicle height at the same and desired level during the travel. In addition, the air suspension springs allows for tilting and lowering the bus to enable passengers to get on and get off easily. It is generally required to mount two air suspension springs on the front axle and four air suspension springs on the rear axle

The air suspension springs of trailers /semi-trailers are preferred and used to prevent loaded cargo and ensure driving safety by preventing adverse effects to arise from structure of the road such as libration, tilting, jumping, roaming. In addition, the air suspension springs are proven to protect the vehicle and load better than the steel leaf spring systems.

In general, while there are two air suspension springs in each axle, there is lifting spring in one axle in vehicles with multiple axles in order to prevent the tires when the vehicle is empty.

Secondary suspension; The main objective of Aktaş Holding is to consolidate this strong bond through strategic moves and to maintain its innovative and value-oriented approach.

Through high technology and quality workforce, Aktaş conveyed its experience of many years in air suspension systems to tracks and made investments in this field. The work with train bellows system was initiated in 2008 with the installation of the bellows to the pneumatic secondary suspension systems in ABB vehicles of Istanbul Transportation Company for testing purposes. Upon successful completion of the testing process, Aktaş established a professional team and production area in mid-2011 for the production and testing of secondary suspension systems. With these investments, Aktaş has made history as the first company that produces train bellows in Turkey."

Aktaş is not a company that only provides service to local market in rail systems suspension systems sector. It also continues its activities with high energy to become a global player.
