A kind of crossed rod type wheel is to connecting device, comprise connecting rod arranged in a crossed manner, the two ends of every root connecting rod are connected to two wheels on a diagonal line on axle box respectively by fastening structure, mount pad is fixed with on axle box at wheel, fastening structure is located on mount pad, by arranging mount pad at wheel on axle box, achieving wheel to the application of connecting device on band axle box bogie truck, improve stability and the curving performance of bogie truck operation.
Further, described fastening structure is ball pivot, the outside of ball pivot is fastened on described mount pad, the movable end of ball pivot is connected with the end winding support of described connecting rod, because the radial rigidity of ball pivot is large, make the length of connecting rod non-stretchable, thus improve anti-diamonding ability, normal curving performance can not be affected again.
Further, described mount pad comprises permanent seat and Connection Block, one end and described wheel of permanent seat are fixed axle box, the other end and Connection Block fastening, the outside of described fastening structure is fastened on Connection Block, by this split type permanent seat and Connection Block, Each part part structure is simple, the convenient replacing to certain part.
Or described mount pad is structure as a whole, one end is fixed on wheel on axle box, and the bearing surface of mount pad is vertical with the setting direction of described connecting rod, and all-in-one-piece mount pad makes easy to connect.
Further, the bearing surface of described Connection Block is vertical with the setting direction of described connecting rod.
Principle of work of the present utility model is: for the bogie truck with axle box, the special crossed rod type wheel arranged is to connecting device, two crossbars are connected respectively to wheel on two diagonal lines on axle box, crossbar end adopts spherical hinge structure, by fastener with Connection Block to be connected, achieve elasticity location and without wear designs, improve the operation stability of bogie truck.
Compared with prior art, the utility model has the following advantages:
1) crossbar being arranged on wheel on axle box, making to take turns bogie truck connecting device being applicable to welded frame, improve the operation stability of this bogie truck when turning to and curving performance.
2) connect connecting rod and mount pad by the mode of ball pivot, achieve elasticity location and without wear designs, maintenance cost is low, and reliability is high.
3) mount pad adopts integral structure or split-type structural, flexible and changeable, can make suitable selection as the case may be.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is local structure schematic diagram of the present utility model;
Fig. 3 is local structure schematic diagram in embodiment 2 in the utility model;
Wherein, 1. permanent seat, 2. Connection Block, 3. connecting rod, 4. axle box, it is right 5. to take turns, 6. Integral mounting base, 31. ball pivots.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
