Technical field
The utility model relates to railway passenger car bogie, especially relates to a kind of broad gauge steel spring railway passenger car bogie with good applicability, reliability.
Background technology
Bogie truck is a passenger train traveling portion, and China mainland does not have the broad gauge railway circuit.Gauge is that 1676 passenger train has very big field of application in South Asia, as states such as Pakistan, Sri Lanka, Bangladesh, India.The following passenger vehicle of 80km/h that these countries use at present all is the product of 20th century 60, the seventies, and running velocity is low, average velociity 50-60km/h, and vehicle reliability is poor.The broad gauge bogie truck of running velocity 120km/h has air bellow, two kinds of structures of steel spring at present, all adopt general steel plate 16MnR material, the air bellow bogie truck adopts no bolster structure, one is to adopt the pivoted arm location to realize the axle box location, with addition of vertical damper, two is to adopt the air bellow carrying, with addition of lateral damper, adopts torsion bar mechanism for preventing side rolling of train carriage to realize the anti-function of sidewindering simultaneously.Steel-spring bogie adopts the shaketable structure, bolster, spring plank carrier adopt welded structure, one is to adopt the pivoted arm location to realize the axle box location, with addition of vertical damper, adopt horizontal control stalk device to provide one to be located lateral rigidity, two is to adopt the steel spring carrying, and with addition of vertical damper, adopting lateral connecting rod device control two simultaneously is lateral stiffness.Because it is that Rubber Parts such as shock absorber, anti-side rolling torsion rod need specialized factory's maintenance that the air bellow bogie truck adopts air bellow,, maintenance cost is higher; Because steel-spring bogie adopts one to be shock absorber, horizontal control stalk device, lateral connecting rod device etc., structure is comparatively complicated, the corresponding increase of maintenance cost, simultaneously because two kinds of bogie truck welding steels adopt common 16MnR steel plate, the steel plate resistance to corrosion is relatively poor, therefore can't satisfy the utilization requirement under the salt fog climatic conditions.
The utility model content
Technical problem to be solved in the utility model provides a kind of maintenance requirement and all very low steel spring broad-gauge passenger bogie truck of utilization maintenance cost of using, and this bogie truck more can adapt to comparatively abominable circuit, environmental conditionss such as salt fog.
For solving the problems of the technologies described above, the utility model provides a kind of broad-gauge steel-spring bogie, comprise that framework composition, wheel are to registration device, central mounting device, foundation brake rigging, integral lifting device, it is characterized in that: wheel adopts the guide colume type wheel to location structure to registration device, and the central mounting device adopts the shaketable structure.
The central mounting device comprises bolster, spring plank carrier, drawing pull bar composition, spring composition, horizontal buffer, side bearing, vertical damper, bolster middle part skew symmetry is provided with the radial type drawing pull bar and forms, bolster parallel connection between spring plank carrier is provided with vertical damper and spring is formed, bolster is provided with side bearing, be provided with side bearing above the side bearing, the side bearing side is provided with horizontal buffer.
Framework is formed the welding of employing weather-resistant steel plate; The axle box material adopts B level steel, and bolster, spring plank carrier adopt the cast steel structure, and material adopts B level steel.
The big span bolster spring of the utility model utilization replaces air spring provides lateral stiffness, torsion bar mechanism for preventing side rolling of train carriage, lateral connecting rod device have been cancelled, by one is that to have replaced axle box pivoted arm location and be vertical damper, horizontal control stalk device guide pillar location, simple in structure, maintenance cost is low; Framework is formed the material of the anti-Hou Gang of employing as steel plate, and the axle box material adopts B level steel, and bolster, spring plank carrier adopt the foundry goods of B level steel, has improved the resistance to corrosion of structure member, is fit to the utilization requirement under the salt fog climatic conditions.
