The basic element of each bogie is its frame, also known as a skid rail, which is supported elastically on wheel sets by bearing links, i.e. main bearings (axle boxes), wheel set guiding systems and 1st degree springing. The frame accommodates all mechanisms and devices of the bogies, such as the mechanical components of the bogie for the transmission of tractive forces, vibration damping, guiding wheelsets, etc., as well as the drive units and brake system components.
The frame of the bogie must be able to withstand static and dynamic loads. It must be sufficiently rigid and as light as possible. Its shape depends on the number of wheelsets and their guidance, the type of transmission of tractive forces, the method of suspension, the type of drive and braking systems used, design speed, etc.
The frames of the bogies bind together wheel sets, drive units and brake units. The design of the frames determines the driving safety and reliability of the whole vehicle.
The frame is also responsible, as mentioned above, for supporting the bodies and mediating the transmission of tractive forces to them – they are elements mediating between wheel sets and the body.
We sell and service frames and accessories:
– New and used frames (after twist tests)
– Kingpin sockets
