AI Technical Summary
In the existing technology, the anti-detachment structure of the connecting pin of the radial device of the wheelset of the railway freight car bogie is simple, and there is a gap between the anti-detachment bolt and the pin, which makes it easy to break due to vibration and collision, resulting in insufficient connection reliability and affecting driving safety.
A two-stage anti-loosening structure is formed by using a slotted nut and a cotter pin. The threaded part of the connecting pin cooperates with the slotted nut to form the first stage of anti-loosening, and the cotter pin is fixed at the opening of the slotted nut to form the second stage of anti-loosening, eliminating the risk of gap collision.
It significantly improves the connection reliability and driving safety of the wheelset radial device, enhances the straight-line running stability and curve passing performance of the vehicle, and reduces wheel flange wear and noise.
