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

Problems solved by technology

The existing technology generally adopts rigid side bearings, and the center plate is fully loaded for traction; during the operation of the vehicle, due to the longitudinal traction force and the lateral swing of the vehicle, there will be rigid impact between the upper and lower center plates; again, due to manufacturing and installation errors, also The force between the upper and lower center plates is uneven, especially when the car body rolls sideways during operation, the upper center plate transmits the load through the edge, which may easily ca

Example Embodiment

[0020] Attached below Figure 1-5 An embodiment of the present invention is described.

[0021] A two-axle bogie with locking function has a frame 1 with an axle 2 mounted on the frame 1 and a wheel-to-axle box 3 at both ends of the axle 2, and a driving device 4 is mounted on the axle 2 at one end of the frame 1, The center of the beam 6 of the frame 1 is provided with a center ball pin traction device, and the center ball pin traction device is fixedly connected to the frame 7 located above the frame 1, and the frame 1 is provided with constants located on both sides of the center ball pin traction device. The contact elastic friction side bearing 9 and the constant contact elastic friction side bearing 9 are supported at the bottom of the frame 7 and cooperate with the center ball pin traction device to support the frame 7 above the frame 1, and the side beam 8 of the frame 1 is provided There is a locking device that forms a rigid support between the frame 1 and the frame 7,...

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.

Description

technical field [0001] The invention belongs to the technical field of railway machinery design and manufacture, and in particular relates to a two-axle bogie with a locking function. Background technique [0002] With the development of my country's railway construction, various engineering vehicles and railway rescue vehicles have become necessary equipment. In the operation of engineering vehicles or rescue vehicles, due to the stability requirements of the equipment on the frame, it is necessary that there is no relative movement between the bogie wheelset and the frame, and between the frame and the frame to prevent the frame from swinging left and right and prevent the vehicle from tipping over. , and the vehicle needs to be stable when operating at low speed. The existing technology generally adopts rigid side bearings, and the center plate is fully loaded for traction; during the operation of the vehicle, due to the longitudinal traction force and the lateral swing ...
