Abstract

The invention provides a composite axle box positioning device and a processing and assembling method thereof. The device is characterized in that a composite positioning structure of combining a steel spring with a rubber spring is adopted, so that zero clearance and zero wear limit and assembling for positioning of an axle box is realized so as to improve the horizontal and longitudinal rigidities and proper vertical rigidity of the axle body positioning device synchronously. The composite axle box positioning device comprises a positioning guide column which is vertically connected with a structural frame through positioning bolts, a lower clamping plate and an upper clamping plate which are arranged on a mounting seat of the axle box body, and a steel spring is clamped between the lower clamping plate and the upper clamping plate. A groove around the positioning guiding column is arranged at the lower clamp plate; and a rubber spring is sleeved in the groove and the on the positioning guiding column; the rubber spring is formed by vulcanization of rubber and steel plates and is pressed in the lower clamp plate; the rubber spring is matched with the lower clamp plate for use, longitudinal and horizontal rigidities and flexibilities of the axle box positioning device are provided for a suspending system of a steering frame, thereby ensuring stability when the steering frame runs at a high speed.

Description

technical field [0001] The invention relates to a composite axle box positioning device applied to rail vehicle bogies and a processing and assembling method thereof, belonging to the field of mechanical manufacturing. Background technique [0002] With the speed increase of the existing trunk line railways and the vigorous development of urban rail transit in China, higher design requirements are put forward for the bogie structure and performance in order to meet the high-speed operation of rail vehicles. [0003] The bogie of the usual structure uses the axle box body of the primary suspension system to flexibly locate the wheelset and frame. In order to improve the critical driving speed of the vehicle and ensure the smoothness and stability of the high-speed operation of the vehicle, the primary axle box positioning device is required to have relatively large lateral and longitudinal rigidity and appropriate vertical rigidity. At the same time, in order to meet the req...
