Steering system for the railway vehicles using the relative displacement between the car body and the bogie

摘要

PURPOSE: A steering device for a railway vehicle using relative displacement between a vehicle frame and a bogie is provided to improve insufficient steering performance of a self steering mode, to reduce lateral force between wheels and railroads, and to reduce attack angles. CONSTITUTION: A steering device for a railway vehicle using relative displacement between a vehicle frame and a bogie comprises front and rear distortion bars(110,120), first and second steering links(130,132), third and fourth steering links(140,142), first and second connection links(150,152), and first and second bolster brackets(160,162). The front and rear distortion bars are installed in a bogie frame for a railway vehicle. The first and second steering links are symmetrically connected to the left and right sides of the front distortion bar to be respectively connected to front left and right axle boxes(340,342). The third and fourth steering links are symmetrically connected to the left and right sides of the rear distortion bar to be respectively connected to rear left and right axle boxes(344,346). The first and second connection links are respectively connected to the right side of the front distortion bar and the left side of the rear distortion bar. The ends of the first and second links are connected to the first and second bolster brackets.
