Problems solved by technology

[0003] Although my country's rail transit industry has developed rapidly in recent years, due to factors such as the continuous increase in train speed, the continuous lightweight of the car body, and the increase in passenger volume, various unexpected problems in the actual operation of the vehicle have also intensified. Especially for trains running in bad weather areas, such as the Lanzhou-Xinjiang high-speed railway line with a total length of more than 1,700 kilometers, passing through desert areas, typhoons sometimes even reach level 12 or above, and the risk of train overturning is greatly increased, which seriously affects the safety and stability of train operation

Embodiment

[0045] Such as figure 1 and figure 2 As shown, the present invention provides a rotor inertia type anti-rolling shock absorber for rail vehicles. For the installation on the above, the carrier frame 2 is U-shaped by two "L" beams connected by bolts, and connected with the underframe of the car body through the lifting hole 1; the rotor unit includes the rotor shaft 7 and the rotor mass 8, and the rotor unit can pass through Connecting electricity to realize rotation drive; the rotor mass 8 is a cylindrical structure with a through hole in the middle;

[0046] Such as image 3 As shown, the rotor shaft 7 is a stepped shaft structure; the rotor mass 8 and the rotor shaft 7 are interference fit to ensure that there is no relative rotation between them, and a rotor is arranged between the two ends of the rotor shaft 7 and the balance frame 3 Shaft bearing 9, the outer ring of the rotor shaft bearing 9 is fixed with the balance frame 3, so that the rotor unit can rotate relativ...

Abstract

The invention relates to a rotor inertia type anti-side-rolling-force vibration absorber for a railway vehicle. The vibration absorber is fixedly connected with a vehicle body chassis of the railway vehicle and is arranged in the width direction of the vehicle, and the vibration absorber comprises a U-shaped bearing frame, a balancing frame which relatively and horizontally rotates in the bearing frame through a balancing shaft, and a rotor unit which is relatively and vertically electrically driven to rotate in the balancing frame. Compared with the prior art, the vibration absorber has the advantages of being simple in structure, easy to control, high in reliability, capable of effectively enhancing the side rolling resistance of the railway vehicle, wide in working frequency domain, wide in application and the like.

Description

technical field [0001] The invention relates to the technical field of rail transportation equipment vibration reduction, in particular to a rotor inertia type anti-side rolling force shock absorber for rail vehicles. Background technique [0002] With the rapid development of my country's national economy, regional economic and trade exchanges have become more frequent, and the grand goal of building a transportation power has gradually been put on the agenda. In the construction of comprehensive transportation networks, rail transit construction has attracted much attention. From the "eight vertical and eight horizontal" railway network From the construction of the high-speed train known as "China's business card" to the world, the construction of rail transit has already become an important manifestation of my country's comprehensive national strength. At the same time, rail transit also has many advantages such as environmental protection, safety, and convenience. etc. pla...
