Abstract
A bogie lateral movement-limiting system capable of effectively restricting the lateral movement of a derailed bogie. The system comprises derailment prevention guards (62a, 62b) laid along the inside of paired left and right rails, and a lateral movement-limiting device (52) installed on the lower part of the bogie (30). The device (52) has a stopper (51) projecting downward at a position between the wheels of the bogie and slidingly contacts with the inner surfaces of the derailment prevention guards (62a, 62b) in case of a derailment of bogie.
Claims6
A bogie lateral movement-limiting system for restricting lateral movement of a bogie during derailment of a vehicle traveling on paired rails, the system comprising:
- a derailment prevention guard device laid along inside of the paired rails within construction gauge;
- and,
- a lateral movement-limiting device attached to a lower part of the bogie;
- wherein the lateral movement-limiting device has a stopper extending downward from a position inside of wheels of the bogie and within the clearance limit for rolling stock, the stopper being positioned proximate a midpoint of the bogie in the width direction such that interference of the stopper and the derailment prevention guard device is prevented during normal operations, but sliding contact of the stopper and an inner face of a derailment prevention guard is allowed upon derailment.
