Rubber-Metal Spring system
We are specialized on primary springs, standard buffers and bogie parts, bushings, vibration damper, railway couplings, as well as air springs and air spring systems for secondary suspension (multi layer spring and conical spring).
Primary Suspension Spring (Conical spring):
Transmission of all vertical and horizontal forces between wheel-set and bogie.
Installed in the primary spring system for absorbing shock and vibration in the chassis.
Installed in the primary spring system to transfer all braking, traction and lateral forces (vertical and horizontal forces) between wheel-set and bogie.
Secondary Suspension Spring
In case of failure of the primary suspension spring.
The air spring ensures elastic storage of the car body on the bogie.
Air spring (suspension) bellow
Installed in the secondary spring system.
Lateral buffer (Elastomer)
Element for supporting the car body the bogie when traveling on a turn.
Rolling Damper "Inter-Car Damper"
This component is intended to improve the sinusoidal course of the bogie and thus can prevent a rolling of the rail vehicle.
Power transmission in the bogie.
Transmission of braking and driving forces between pivot and bogie.
Serves to improve driving comfort on challenging routes. It is installed on the roof of the car body.
Element for damping radial and axial movement.
Resilient wheel (low noise)
Rubber body for acoustic decoupling between wheel tire and wheel hub.
Steel spring systems
Hot forming technology enables to produce and supply springs in a wide range of size, accuracy and design. Individual customer requirements are verified by finite element method to assess accuracy of the load parameters.
The hot-formed compression steel springs are further treated and processed to achieve an optimal strength and toughness ratio of the material, ensuring high operation stability and durability of shape.
The most advanced surface treatment technologies are used to ensure long life without fatigue.
Hot forming technology bears springs in a wide range of size and accuracy.
Hydraulic spring systems
We can also provide you with high quality hydraulic damper according to international standards.
