5.More important,we also have our strict series quality control such as Six-Axle Testing ect.
We have the rolling lobe air spring, bellow rolling lobe air springs, sleeve type air spring and convoluted ir spring, they are used on MAN, DAF Volvo, Mercedes bens BMW ect truck tralier and cars
Rolling Lobe Air Spring
Rolling Lobe Air Springs are usually used in buses and light commercial vehicles. Recently they also started to be used in trucks by vulcanizing metal connection parts. Besides, they are used as a third axle spring or lifting spring in some vehicles.
The products with both beads in conical shape can be easily mounted to the plates and pistons which are produced with appropriate diameter and conical structure and also can be easily dismantled from them. Except the types which are especially produced with 4-6 layers of cord fabric, the cylindrical types can be attached symmetrically in both directions. However, in conical types, the section with short diameter must be fitted to the pistons (chassis-bottom), the other section with wide diameter must be connected to the plates (chassis-top).
Owing to the special rubber compounds, all air spring types can be used at a working temperature between -40°C and 70°C without any dysfunction. For different various application areas, they have different assembly heights, operation pressure intervals, operation spaces, loading capacities and working frequencies.
Rolling Lobe Air Spring with Metal Parts
Rolling lobe air springs with metal parts are mostly used in trucks and trailers. Rolling lobe air springs with metal parts are also used in some types of busses. Besides, they are used as a third axle spring or lifting spring in some vehicles.
In these types, a top crimping plate provides the fitting of the air spring to the chassis. Attachment to the piston on the axle connection point is implemented by a bottom plate vulcanized into the air spring bellow or individual bottom clamping plate combined with the rubber body. These products are produced as cylindrical or as conical forms. Compared to the rolling lobe air springs (air springs without top plate), they are used especially in heavy load transportation. Loading capacity of air spring can go up to 4,5 tons and can operate at up to 700 mm operation height.
These types, which consist of special rubber compounds, work functionally under low temperatures (-40°C) and high temperatures (70°C) like all air spring types. There are different various types of rolling lobe air springs which have different assembly heights, operation pressure intervals, operation spaces, loading capacities and working frequencies.
