Shaft end device for bogie of high-speed train

Abstract

The invention relates to a shaft end device for a bogie of a high-speed train. The device comprises a shaft end transition cover and a shaft box end front cover. The device is characterized in that the shaft end transition cover is fitted to the shaft box end front cover through fastening bolts, the connection strength of the bolts is effectively improved, and the reliability of fastening connection of the shaft box end front cover is improved. An ATP / LKJ running speed sensor is arranged on the shaft box end front cover, and a movable plate is matched with the ATP / LKJ running speed sensor. Compared with the prior art, the shaft end device has the advantages that 1, the shaft end transition cover is fitted to the shaft box end front cover through the fastening bolts, the connection strengthof the bolts is effectively improved, and the reliability of the fastening connection of the shaft box end front cover is improved; 2, an ATP / LKJ mode is adopted for a shaft end running speed sensor,a movable plate structure is adopted for a shaft end, and through strength calculation and theoretical analysis, the static strength and fatigue strength of a shaft end structure can meet the application requirement.

Description

technical field [0001] The invention relates to a bogie shaft end device of a high-speed EMU of a rail vehicle, in particular to an axle end structure adapted to the speed signal communication problem of an EMU with a speed below 250Km / h. Background technique [0002] At present, the speed sensors of the existing 380 series EMUs are ETCS models, which cannot adapt to the speed signal communication problem of the existing lines. At the same time, the existing EMU shaft end transition cover and end front cover fasteners have broken and fallen off faults during operation, which has brought huge hidden dangers to safe operation. Contents of the invention [0003] The purpose of the present invention is to provide a bogie axle end device with a new structure, improve the connection strength between the axle end transition cover and the end front cover fastener, enhance the reliability of the fastening connection of the axle box end cover, and meet the static strength and fatigu...
