Abstract

The invention discloses a transverse and longitudinal integrated non-power framework device with temperature-measurable axle boxes, and belongs to the field of railway vehicle framework devices. The transverse and longitudinal integrated non-power framework device comprises a transverse and longitudinal integrated interconnection framework and four annular vibration reduction axle boxes. The transverse and longitudinal integrated interconnection framework comprises two transverse and longitudinal integrated frameworks, and each transverse and longitudinal integrated framework comprises an integrated side beam and an integrated cross beam which are integrally formed. Each integrated side beam comprises a side beam middle section which serves as two bird wing connecting parts and is locatedat a lower position, and two bird-wing-shaped side beam cantilever sections which are symmetrically and fixedly connected to the two ends of the side beam middle section. On the premise that the installation position and the vibration reduction index of a primary suspension axle box device are guaranteed, the overall transverse width size and the turning radius of the bogie are effectively reduced, the curve passing capacity of the bogie is further improved, the vibration influence degree of the bogie on a vehicle body is reduced to the minimum, the balance stability and comfort of the vehiclebody are enhanced, the fatigue loss of the overall structure is effectively reduced, and the overall service life of the bogie and the vehicle body is greatly prolonged.

Description

technical field

[0001] The invention belongs to the field of rail vehicle frame devices, in particular to a horizontal and vertical integrated non-dynamic frame device with a temperature-measurable axle box. Background technique

[0002] In the design of rail train bogies, it is not only necessary to comprehensively consider the structural strength and flexibility of the frame as the main body of the load, the effect of various auxiliary vibration damping components such as anti-snake shock absorbers, and the installation method of the braking mechanism. According to the requirements of different models, the structural form of the primary suspension is comprehensively designed according to the theoretical speed of the train, the load-bearing load, the minimum curvature of the curve and the road conditions such as wind, snow and flying rocks. Various design schemes based on the above-mentioned core ideas have been increasingly improved and complicated, which eventually led to...
