Side beam end cantilever with axle box capable of measuring temperature

Abstract

The invention discloses a side beam end cantilever with a temperature-measurable axle box, and belongs to the field of railway vehicle bogie side beam end devices. The side beam end cantilever comprises a wing-shaped side beam cantilever section, a temperature sensor and an annular vibration reduction axle box. The annular vibration reduction axle box comprises a vibration reduction rubber ring, an axle bearing and an axle box positioning and temperature measurement heat conduction sheath. Vertical and longitudinal torques generated by side rolling motion of a vehicle body can be fully released, all vibrations such as transverse, longitudinal, vertical and snaking torsional pendulum and side rolling generated by a motor and a gear box are effectively eliminated, a more ideal anti-side-rolling balance effect is achieved, the vibration influence degree of the bogie on the vehicle body is reduced to the minimum, a balance stability and comfort of a vehicle body are enhanced, fatigue loss of the whole structure is effectively reduced, the whole service life of the bogie and the vehicle body is greatly prolonged, the production cost is reduced, and the economic value is high.

Description

technical field [0001] The invention belongs to the field of rail vehicle bogie side beam end devices, in particular to a side beam end cantilever with a temperature-measuring axle box. Background technique [0002] Such as Figure 1 to Figure 3 As shown, the frame of rail passenger car bogie can be divided into welded frame formed by butt-welding of multiple plates and cast frame formed by integral casting. The top view formed by two side beams is a letter H-shaped frame. The geometric center of the frame is an integral beam body h or a well-shaped beam body g. Both types of beam bodies are used to form the short middle of the letter H stroke structure. Horizontal, two side beams are symmetrically arranged at both ends of the beam body; the well-shaped beam body is composed of two small beams perpendicular to the side beams. [0003] The design of the side beam structure of the bogie not only needs to comprehensively consider the structural strength and flexibility of the ...

Problems solved by technology

However, this type of isosceles trapezoidal axle box built-in primary suspension structure with double-sided rubber stacks has complicated manufacturing processes and cumbersome disassembly and maintenance procedures, resulting in high manufacturing and maintenance costs.

[0007] In addition, different train design speed requirements or different side beam structures will also have a great impact on the layout space and structural form of the primary suspension device, often resulting in the layout scheme of the old primary suspension device being unable to meet the installation position. and the demand for vibration reduction indicators, it is necessary to overthrow the old reference scheme, and make a design improvement with a new concept
