Bogie frame

Abstract

The invention discloses a bogie frame which comprises two lateral beams and at least one beam. The beam is connected with the lateral beams through rubber joints so as to buffer vertical force borne by a connecting point when a railway vehicle passes through a curve. Torsional moment generated by the vertical force on the bogie frame is reduced, torsional rigidity of the bogie frame is reduced, rate of wheel load reduction and derailing coefficient are reduced, and train operation safety is improved.

Description

technical field [0001] The invention relates to the field of railway locomotives, in particular to a bogie frame. Background technique [0002] With the advancement of science and technology, railway rolling stock has increasingly become the preferred means of transportation for people's daily travel or transportation because of its convenience, speed, and safety. Therefore, the safety of rolling stock is the primary consideration in design. [0003] When the vehicle passes the curve, there are usually two indicators to evaluate the possibility of derailment of the vehicle. One is the derailment coefficient, which is the ratio of the lateral force Q between the wheel and the rail to the vertical force P, where the vertical force is usually the wheel weight. For a moving train, its own weight and the load it bears are usually constant, so the weight transmitted to the wheel set is also constant. Under the condition of constant wheel weight, the greater the speed of the train,...
