Title:
LOCKING MECHANISM FOR GAUGE-CHANGEABLE WHEEL SET, GAUGE-CHANGEABLE WHEEL SET AND GAUGE-CHANGEABLE BOGIE
Document Type and Number:
WIPO Patent Application WO/2020/253444
Kind Code:
A1
Abstract:
A locking mechanism (3) for a gauge-changeable wheel set and the gauge-changeable wheel set, wherein the locking mechanism (3) comprises a traction electromagnet (32) and a locking pin (33), wherein the traction electromagnet (32) comprises a traction coil (32-1) and a movable iron core (32-2) which is controlled to move by the on-off of the traction coil (32-1), the locking pin (33) is fixedly connected to one end, away from the traction coil (32-1), of the movable iron core (32-2), a plurality of locking holes (41) are formed in the inner side hub of a wheel (4) at intervals along the axial direction, the movable iron core (32-2) can drive the locking pin (33) to reach into or leave the locking holes (41), so as to lock or unlock the wheel (4). The gauge-changeable wheel set comprises the wheels (4), axles (5) connected with the wheels (4) through splines, the locking mechanism (3) and a lateral driving mechanism (1), wherein the two ends of the axles (5) outside the wheels (4) are respectively supported in an axle box body (7); the locking mechanism (3) is respectively arranged on the inner side of each wheel (4), the transverse driving mechanism (1) is respectively arranged on the outer side of each wheel (4), and is fixed on the axle box body (7), the transverse driving mechanism (1) comprises an electric cylinder (11), the extending end of the electric cylinder (11) is used for pushing or pulling the unlocked wheels (4), so as to realize the gauge change of the wheels (4).
