Abstract
The utility model relates to a motor train bogie frame of a high-speed motor train unit, which comprises two side beams, two beam steel tubes, two longitudinal beam assemblies and four brake hanger assemblies, wherein, the bogie frame is an H-shaped welding bogie frame; either side beam adopts a four-plate box structure; the longitudinal beam assemblies between the two beam steel tubes adopt an integrated design and bridge the two beam steel tubes; a long riser is in cross assembly welding with two short risers and forms the box structure together with an upper cover plate and a lower cover plate; both sides of the box structure are provided with a motor hanger and a gear box hanger, and the middle is provided with a transversal damper base; a transversal side beam connecting base adopts a forging and various section design; one end of the transversal side beam connecting base is in butt joint and assembly welding with the beam steel tubes, and the other end is in assembly welding with the side beams into the box structure; the brake hanger assemblies are in assembly welding with the side beams into the box structure; and brake pad bracket hangers in the brake hanger assemblies are welded on the inner risers of the side beams. The utility model has enough fatigue intensity and favorable manufacturability and can satisfy the requirements for the normal running of the bogie frame of a high-speed motor train unit.
Description
Technical field
The utility model relates to a kind of motor car bogie framework of EMU, especially relates to the EMU motor car bogie framework of the integrated design of a kind of motor hanger, gear box bracket, longitudinal beam, lateral damper seat and horizontal curb girder Connection Block, braking flap seat optimal design.
Background technology
The motor car bogie framework is the agent structure part of EMU motor car bogie.What influence the panel work performance mainly is the structural strength and the anti-fatigue performance of framework.The motor hanger of motor car bogie framework, gear box bracket, longitudinal beam composition, horizontal curb girder Connection Block, braking flap seat are the key positions of estimating the motor car bogie framed intensity.The motor hanger of existing motor car bogie framework, gear box bracket, longitudinal beam, lateral damper seat adopt the split design, exist function disperse single, with big, the problems such as weld stress is big, strength at repeated alternation is low, anufacturability difference of complex interfaces, welding capacity of crossbeam steel pipe; The unreasonable structure of the horizontal curb girder Connection Block of framework and braking flap seat, strength at repeated alternation is low.The fault of construction of therefore existing motor car bogie framework has reduced its strength at repeated alternation grade and service life, can not satisfy the safe operation requirement of EMU vehicle, has improved the operation and the maintenance cost of EMU greatly, and is less economical.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can satisfy EMU vehicle safety operation requirement, reduces operation and maintenance cost, and the EMU motor car bogie framework that anti-fatigue performance is good is to overcome the defective that background technology exists.
For solving the problems of the technologies described above, the utility model provides a kind of motor car bogie framework of EMU, comprise two curb girders, two crossbeam steel pipes, two longitudinal beams are formed and four braking flap seats compositions, framework adopts H type welded frame, curb girder adopts four plate box-structures, it is characterized in that: the longitudinal beam between two crossbeam steel pipes is formed and is adopted integrated design, across two crossbeam steel pipes, comprise long riser, short riser, upper cover plate, lower cover, motor hanger, gear box bracket, the lateral damper seat, a long riser, two short risers intersect assembly welding and upper cover plate, lower cover is formed box type construction, two ends are motor hanger and gear box bracket, and the centre is the lateral damper seat; Horizontal curb girder Connection Block adopts the design of forging variable section, and an end docks assembly welding with the crossbeam steel pipe, and the other end becomes box type construction with the curb girder assembly welding; Braking flap seat composition becomes box type construction with the curb girder assembly welding, brake plate support flap seat during the braking flap seat is formed and the welding of curb girder inner vertical plate.
The utility model is owing to the longitudinal beam between two crossbeam steel pipes is formed the employing integrated design, and two ends are motor hanger and gear box bracket, and the centre is the lateral damper seat; Horizontal curb girder Connection Block adopts the design of forging variable section, and an end docks assembly welding with the crossbeam steel pipe, and the other end becomes box type construction with the curb girder assembly welding; Braking flap seat composition becomes box type construction with the curb girder assembly welding, and therefore brake plate support flap seat during the braking flap seat is formed and the welding of curb girder inner vertical plate have enough strength at repeated alternations, favorable manufacturability, can satisfy the normal operating needs of EMU motor car bogie.
