Two-axle bogie with locking function
A bogie and functional technology, which is applied in the direction of the bogie, the device for lateral relative movement between the bottom frame and the bogie, the installation of the axle box, etc., which can solve the problem that the rigid side bearing cannot generate stable rotational friction torque and cannot meet the requirements of railway equipment rescue. Equipment speed requirements, inability to effectively suppress vehicle meandering, etc., to achieve large bearing capacity, meet bearing requirements, and prevent vehicles from overturning

Abstract
The invention provides a two-axle bogie with the locking function. The bogie is provided with a framework. A center ball pin traction device is arranged in the middle of a transverse beam of the framework and fixedly connected with a frame located above the framework. A constant contact elastic friction side bearing is supported at the bottom of the frame and matched with the center ball pin traction device to support the frame above the framework, and side beams of the framework are provided with locking devices for enabling the framework and the frame to form rigid supporting and enabling the framework and a wheel set axle box to form rigid supporting. After the framework and the wheel set axle box form rigid supporting, and the framework and the frame form rigid supporting, the phenomenon that the frame swings left and right during vehicle equipment is operated is effectively avoided, the phenomenon that a vehicle tips over is avoided, the traction mode is central traction, and the requirement for low-speed walking of the vehicle is met; when the vehicle is operated at high speed, a center ball pin and the constant contact elastic friction side bearing are matched for use for spherical center plate traction, head shaking snake motion of the bogie is limited, the rolling pendulum motion of the vehicle body is limited, and the anti-dumping safety of the vehicle is promoted.
