Device for allowing railway construction machine to ride on rail or road with same axle, has actuator rotating hub-carrier to raised position for rail ride function, and rotating hub-carrier to lower position for road ride function

摘要

The device has a hub-carrier (7) supporting a pneumatic wheel (1) where the hub-carrier is supported by a shaft (3) and a bearing (4), and the hub-carrier is rotatable about an axis (10). Another hub-carrier (8) is supported by another shaft (31), where the latter hub-carrier supports an iron wheel, and is connected through bores (13) in a bridge that connects the latter hub-carrier to a frame of a machine. An actuator (11) rotates the former hub-carrier to a raised position for a rail ride function, and rotates the former hub-carrier to a lower position for a road ride function.
