Abstract
The utility model relates to the field of metallurgy, in particular to a wheel guide mechanism for a steel ladle or iron ladle carrier vehicle. The wheel guide mechanism is characterized in that one end of a guide shaft is mounted on a support through a spherical roller bearing. A needle bearing is fixed at the other end of the guide shaft. A lateral wheel which can freely rotate along the central axis of the guide shaft is mounted on the outer ring of the needle bearing. The lateral wheel is disposed on the upper side of a standard rail. A knuckle bearing is fixedly mounted in the middle of the guide shaft. A disc spring seat is mounted on the outer ring of the knuckle bearing. A disc spring set is sleeved on the shaft of the disc spring seat. The disc spring set is located between a base plate of the disc spring seat and a support side plate.
