Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of monorail vehicle stabilizing wheel, in particular to a monorail vehicle stabilizing wheel support deflection structure. BACKGROUND

[0002] The straddle monorail traffic is a track traffic system in which vehicles run on the track beam combined with the track. It generally adopts elevated lines and is supplemented by ground or underground laying when necessary. The vehicle adopts rubber tires. In addition to the running wheels, there are guide wheels and stabilizing wheels on both sides of the bogie, which are clamped on both sides of the track beam to ensure the safe and stable running of the vehicle along the track. The stabilizing wheel of the monorail traffic vehicle plays a supporting and stabilizing role.

[0003] As provided in Chinese patent publication No. CN207466656U, a straddle monorail bogie, two groups of stabilizing wheels are connected to the running wheels and arranged on both sides of the track, and two stabilizing wheels are arranged side by side in each group. The stabilizing wheel takes the side of the track as the running surface. When the vehicle is subjected to centrifugal force, the stabilizing wheel mainly plays a stabilizing role to prevent the vehicle from overturning. At the same time, due to the arrangement of two stabilizing wheels on one side, the stabilizing wheel can also play a certain guiding role. The guide wheel and the stabilizing wheel jointly play a role in buffering the lateral vibration of the vehicle.

[0004] In the prior art, the stabilizing wheel is located at the bottom of the vehicle and contacts the monorail track to maintain the stable running of the vehicle through friction with the track. The stabilizing wheel bears the weight and impact force of the vehicle during running and will continuously contact the track during the running of the vehicle. The use frequency is very high, which is easy to cause wear. If the stabilizing wheel is seriously worn, the contact area between the wheel track and the vehicle will be reduced, which weakens the supporting and stabilizing effect of the stabilizing wheel on the vehicle, and further affects the stability and stability of the vehicle.
