Abstract
The utility model provides a draw gear of high-speed EMUs bogie, includes that draw beam, draw beam bottom gland, central authorities pull the node and constitute, pull rod and pull rod node, its characterized in that: the draw beam is a casting structure, and the pull rod nodes are pressed in holes at two ends of the pull rod. The utility model has sufficient fatigue strength and good processing performance, and ensures the safe operation of the bogie; through reasonable design of the pull rod and the node device thereof, the pull rod and the node are relatively independent through cold pressing matching, the condition that one pull rod is damaged and all the pull rods are replaced is avoided, and meanwhile, the labor intensity and the cost of maintenance are also reduced.
Description
Technical field
The utility model relates to a kind of draw gear of trolley coach bogie truck, especially relates to a kind of draw gear of EMU bogie truck.
Background technology
Existing draw gear mostly is welded structure, there are anufacturability difference and the low defective of fatigue resistance performance, pull bar and node place mandrel metal are one by rubber three partial vulcanizations simultaneously, then need integral replacing if a position is damaged, and bring great inconvenience to maintenance and repair.
The utility model content
Technical problem to be solved in the utility model provides a kind of by casting the draw gear that draw beam and split type drawing pull bar are formed the trolley coach bogie truck, and this installs certain position damage and need not integral replacing, the maintenance and repair convenience.
For solving the problems of the technologies described above, the utility model provides a kind of draw gear of EMU bogie truck, comprise draw beam, draw beam bottom gland, central authorities' traction node composition, pull bar and pull bar node, it is characterized in that: draw beam is a cast structure, and the pull bar node press-fits in two stomidiums of pull bar.
The utlity model has enough strength at repeated alternations, shop characteristic is good, guarantees the safe operation of bogie truck; By the design of rational pull bar and node apparatus thereof, cooperate by colding pressing that pull bar and node are realized is relatively independent, avoided bad one and change whole situations, the while has also been reduced the labour intensity and the cost of maintenance and repair.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
With reference to Fig. 1,2, the utility model comprises that draw beam 1, draw beam bottom gland 5, central authorities' traction node form 2, pull bar 3 and pull bar node 4, and draw beam 1 is a cast structure, pull bar node 4 press-fit in two stomidiums of pull bar 3 and with draw beam 1 bolted connection.Central authorities' traction node is formed 2 and is press fit in the draw beam 1.
Claims (1)
1, a kind of draw gear of EMU bogie truck comprises draw beam, draw beam bottom gland, central authorities' traction node composition, pull bar and pull bar node, and it is characterized in that: draw beam is a cast structure, and the pull bar node press-fits in two stomidiums of pull bar.
