Locomotive bogie TRIAX

standard gaugeelectric3-axle

The structure of the bogie is built around a welded H-frame integrating the central axle. The two other axles are incorporated in articulated bissels which are connected to the main structure. In bogie use, the bogie frame is equipped with a spherical toe cap and side skirts. The bogie can be delivered in a carrier version or in a motorised version with 1 to 3 CFD traction motors. Each axle has its own brake blocks and coil spring suspensions. The axle articulation system designed by CFD allows the vehicle to pass through very tight curves without damaging the track and to reach high speeds (90 km/h or more) while maintaining good stability in straight lines or curves. The configuration of the TRIAX is such that the axles have a minimum angle with the rail in curves, limiting friction at the wheel flange: The central axle is fixed in relation to the chassis. The centre axle is fixed in relation to the chassis. Each end axle is attached to a bissel which can pivot in relation to the chassis. The movement of the bissel in relation to the bogie frame can be controlled by the vehicle or can be passively actuated, the aim being to make the rear axle of the bogie pivot in the opposite direction to the front axle when passing through a curve. Mechanical elements and shock absorbers are used to ensure that the system operates correctly Application Heavy locomotives Special cars Works trucks Other rolling stock.
