Normal operation.
Chinese utility model patent CN201520420316.6 discloses a kind of magnetic-levitation train track joint for track panel comprising
The transition key of adjacent two pieces of sections of track and the support wheel process for train, the abutting end of two adjacent sections of track open up
There is keyway, the transition key is connected in two keyways, and the sled of the upper surface of the transition key and the section of track supports
Face is concordant.Due to the effect of transition key, rail gap is efficiently filled, and support wheel can walk on transition key when passing through rail gap, from
And effectively reduce impact of the rail gap to support wheel.Rail joint in the patent is when passing through rail gap to reduce support wheel
Impact, can not reduce impact when brake clamp passes through rail gap.
Therefore, how to reduce and even be eliminated because rail gap causes impact of the magnetic-levitation train in mechanical braking, it is steady to improve vehicle
Qualitative is those skilled in the art's technical issues that need to address.
