Abstract
An aluminum alloy casting sleeper beam of a motor train unit comprises an air spring base, an S-shaped vibration absorber base, a traction base, a side rolling resisting torsion bar base, casting auxiliary holes, casting ribs and auxiliary holes. The aluminum alloy casting sleeper beam is characterized by comprising an upper sleeper beam, a middle sleeper beam and a lower sleeper beam, the lower sleeper beam is provided with the S-shaped vibration absorber base and the air spring base, the traction base and the side rolling resisting torsion bar base are arranged on the two sides of the lower sleeper beam respectively, the casting auxiliary holes are formed in the lower sleeper beam, the two sides of the lower sleeper beam are provided with the casting auxiliary holes for sand to be cleaned conveniently, the middle sleeper beam is provided with the casting ribs for enhancing the strength of the sleeper beams and the auxiliary holes for air to circulate conveniently, and the auxiliary holes for a stopping core to be floated and placed are formed in the upper sleeper beam. The aluminum alloy casting sleeper beam has the advantages that connection of a bogie and a car body is simplified under the transmission situations that various loads such as traction force, vertical force, transverse force and side rolling force of the car body and the bogie are not affected, and the connection of the bogie and the car body can be removed conveniently.
Description
technical field:
the utility model relates to a kind of railway art, particularly a kind of motor train unit aluminum alloy casting sleeper beam.
Background technology
extensive Develop High-Speed Railway is that China's transport solution transport capacity is supplied with contradiction, drives only way and the inevitable choice of development for hi-tech industry and lifting Transportation Industry international competitiveness.At present, China is accelerating to advance the production domesticization of EMU.Wherein, cast aluminium alloy sleeper beam is bogie truck core component, and the weight of bearing body is also transmitted the vertical and horizontal power in bogie truck operational process, thereby very high to the performance requriements of foundry goods; The cavity of sleeper beam inside is as the auxiliary air reservoir of air spring system, all high to the requirement of leak tightness, comprehensive strength, rigidity simultaneously, and the stressed complexity of sleeper beam easily causes stress to concentrate the service life that affects sleeper beam.
Summary of the invention
the purpose of this utility model is to provide a kind of concentrated sleeper beam motor train unit aluminum alloy casting sleeper beam in service life that affects of stress that can effectively avoid sleeper beam.
the utility model is to realize like this, it comprises air bellow seat, anti-snakelike shock absorber bearing, traction seat, anti-side rolling torsion rod seat, foundry technique hole, casting muscle, auxiliary hole, it is characterized in that it comprises top sleeper beam, middle part sleeper beam and bottom sleeper beam, on the sleeper beam of bottom, be provided with anti-snakelike shock absorber bearing and air bellow seat, traction seat, anti-side rolling torsion rod seat is distributed in the both sides of bottom sleeper beam, on the sleeper beam of bottom, be provided with a foundry technique hole, arrange in the both sides of bottom sleeper beam and facilitate sand removal foundry technique hole, on the sleeper beam of middle part, be provided with sleeper beam intensity casting muscle and be convenient to auxiliary hole mobile in air, on the sleeper beam of top, prevent from being provided with and preventing fuse floating and the auxiliary hole of placement on fuse.
the utility model has the advantages that and do not affecting car body and bogie truck tractive force, vertical power, transverse force, sidewindering in the transmission situation of the various load such as power, simplification bogie truck is connected with car body, makes both connections be convenient to disassemble.
Brief description of the drawings
fig. 1 is the structural representation of motor train unit aluminum alloy casting sleeper beam.
concrete embodiment:
as shown in Figure 1, this motor train unit aluminum alloy casting sleeper beam comprises air bellow seat 1, anti-snakelike shock absorber bearing 2, traction seat 3, anti-side rolling torsion rod seat 4, foundry technique hole 6, foundry technique hole 7, auxiliary hole 8, casting muscle 9, auxiliary hole 10, sleeper beam is by top sleeper beam, middle part sleeper beam and bottom sleeper beam composition, on the sleeper beam of bottom, be provided with anti-snakelike shock absorber bearing 2 and air bellow seat 1, traction seat 3, anti-side rolling torsion rod seat 4 is distributed in the both sides of bottom sleeper beam, on the sleeper beam of bottom, be provided with 20 foundry technique holes 6, arrange in the both sides of bottom sleeper beam and facilitate sand removal foundry technique hole 7, on the sleeper beam of middle part, be provided with sleeper beam intensity casting muscle 9 and be convenient to auxiliary hole mobile in air 10, on the sleeper beam of top, be provided with the auxiliary hole 8 that prevents fuse floating and place stud.
