High-speed train bogie hybrid supporting device and bogie

Abstract

The invention discloses a high-speed train bogie hybrid supporting device and a high-speed train bogie thereof. The high-speed train bogie hybrid supporting device comprises an axle (1) and a double-row tapered roller bearing (2) arranged on the axle (1) in a sleeving mode, and is characterized in that a shaft sleeve (3) and a magnetic suspension bearing are sequentially arranged on the axle (1) in a sleeving mode at the position adjacent to the double-row tapered roller bearing (2); and bearing sleeves (9 and 12) cover the double-row tapered roller bearing (2), the shaft sleeve (3) and the magnetic suspension bearing. A permanent magnet magnetic suspension bearing and double-row tapered roller bearing hybrid supporting mode is adopted to replace an existing cylindrical roller bearing supporting system, the advantages of no contact, no friction, no abrasion, high speed and the like of magnetic suspension are utilized, bearing abrasion generated when a train runs at a high speed is greatly reduced, the service life of a supporting system is prolonged, and the reliability of the supporting system is improved. The vibration and noise of a carriage are reduced, and the riding comfort is improved.

Description

technical field [0001] The invention relates to the technical field of train bogie support, in particular to a high-speed train bogie hybrid support device and a high-speed train bogie. The wear of the tapered roller bearings increases the load carrying capacity of the rail vehicle. Background technique [0002] The high-speed train bogie is a key component to ensure the high-speed operation of the train. As the speed of the train increases, the traction power required by the train increases sharply, and the force of the wheel-rail action becomes greater. Wheel wear, gear wear, bearing wear, brake pads, brake disc wear, wear between various pin sleeves. Abnormal stress caused by uneven wear will have a serious adverse effect on the life and reliability of high-speed power bogies. Magnetic bearings have the advantages of no contact, no friction, no wear, high speed, high precision, no need for lubrication and sealing, etc., and can fundamentally solve the defects of large ...

AI Technical Summary

Problems solved by technology

The above bogie transmission support devices are all supported by mechanical bearings. As the train speed increases, the wear of the bearings will increase, and the vibration and noise of the carriage will increase, reducing the comfort of the ride.
