Non-powered bogie with axle boxes capable of measuring temperature and flexible interconnection framework

Abstract

The invention discloses a non-power bogie with axle boxes capable of measuring temperature and a flexible interconnection framework, and belongs to the field of rail vehicle non-power bogie devices. The non-power bogie comprises a wheel set device composed of wheels and axles, a transverse-longitudinal integrated flexible interconnection framework and four annular vibration reduction axle boxes. The damping requirement for the whole framework is greatly reduced, and the effects of reducing the number of parts and the failure rate, releasing the layout space and maintenance operation allowance of a motor and a gearbox, simplifying the framework size and simplifying the manufacturing process are achieved; and on the premise that the mounting position and the vibration reduction index of the primary suspension axle box device are ensured, the transverse width size and the turning radius of the whole bogie are effectively reduced, the curve passing capacity of the bogie is further improved, and the annular vibration reduction axle box is convenient to mount, dismount and maintain.

Description

technical field [0001] The invention belongs to the field of non-power bogie devices for rail vehicles, in particular to a non-power bogie with a temperature-measuring axle box and a flexible interconnection frame. Background technique [0002] The design of rail train bogies not only needs to comprehensively consider the structural strength and flexibility of the main body of the load-bearing frame, the effect of various auxiliary vibration-damping components such as anti-snake dampers, and the installation method of the braking mechanism. According to the requirements of different models, according to the train’s theoretical speed, bearing load, minimum curve curvature and wind, snow and flying rocks and other road conditions, comprehensively design the suspension mode of the power bogie motor, the placement position of the axle box on the wheel axle, the motor and its There are many factors such as the layout space of the gearbox, the structural form and layout space of t...
