Abstract

The invention discloses a railway vehicle bogie steering shock absorber which comprises a valve seat, a first damping adjusting unit, a second damping adjusting unit and a hydraulic lock are installed on the valve seat, the hydraulic lock is located between the first damping adjusting unit and the second damping adjusting unit, an oil tank is arranged in the valve seat, an oil cylinder is further installed on the valve seat, and a piston rod is arranged on the oil cylinder. A displacement sensor is arranged on the piston rod, an electromagnetic reversing valve and a hydraulic pump are connected between the hydraulic lock and the oil tank, a motor is arranged on one side of the hydraulic pump, and a first one-way valve and a second one-way valve located on the two sides of the hydraulic lock are installed on the valve seat respectively. The damping device can be applied to various rail transit vehicles, plays a role of an anti-snaking damper during straight rail running, provides active acting force between a bogie and a vehicle body during curved rail running, and is used for reducing lateral acting force between a rim of the bogie and a rail, so that abrasion between the rim and the rail is reduced, and the traction performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle suspension, in particular to a steering shock absorber for a rail vehicle bogie. Background technique [0002] Anti-snaking shock absorbers are widely used in the suspension field of rail transit vehicles. They are installed between the bogie and the car body to attenuate high and low frequency nodding and swaying vibrations caused by track irregularities during vehicle operation. With the continuous improvement of the running speed of rail transit vehicles, when the vehicle crosses a curve, the lateral force between the bogie wheel rim and the rail is increasing, and the wear on the wheel rim and rail is intensified. The cost of track grinding affects the life of the vehicle wheelset and track, as well as the traction performance of the vehicle. Ordinary anti-snaking shock absorbers can no longer meet the needs of high-speed vehicles when cornering. [0003] Based on this, a solution is pr...
