Abstract

The invention provides a track vehicle steering frame which comprises a framework and a secondary suspension device. The framework comprises two side beams, two horizontal beams and four braking hanging beams. The two side beams are arranged in parallel at intervals. The two horizontal beams are arranged between the two side beams in parallel at intervals. The side beams are perpendicular to the horizontal beams. Two braking hanging beams are arranged on each horizontal beam in parallel at intervals. The braking hanging beams and the side beams are parallel. A mounting base is arranged at a middle groove of each side beam. The secondary suspension device comprises a plurality of steel springs which are symmetrically arranged on the mounting bases at the middle grooves of the two side beams respectively. The track vehicle steering frame solves the problem that in the prior art, a suspension device of a track vehicle steering frame is formed by an air spring and corresponding components, so that structure is complex, and cost is high.

Description

technical field [0001] The invention relates to bogie technology, in particular to a rail vehicle bogie. Background technique [0002] With the improvement of the capacity of rail vehicles, rail vehicles have become the main means of transportation for people to travel. As one of the most important components in the structure of rail vehicles, the bogie structure directly determines the stability of the vehicle and the comfort of the vehicle. [0003] The bogie of rail vehicles is mainly used to bear the weight of the car body and ensure the safe operation of the vehicle, so that the vehicle can flexibly run along the straight line and pass the curve smoothly; the structure of the commonly used bogie mainly includes: frame, axle box , safety wire ropes, height valves, air springs, torsion bars, wheels, axles, traction center pins, lateral shock absorbers, lateral stops, differential pressure valves, air pipeline devices, etc.; among them, the bogie used to support the car bo...
