Abstract
A non-bolster air spring narrow-gauge cabin bogie comprises a frame, an axle box, a safe steel wire rope, a height valve, a torsion spring, wheels, axle shaft, a traction central pin, a transverse damper, a transverse baffle and a differential pressure regulator. The utility model is characterized in that the side beam of the frame and the axle box are provided with an axle box rubber spring therebetween, the end of the axle shaft is provided with a self-sealing cone roller bearing, two beams of the frame are provided with a traction rubber stack, the end of the side beam of the frame is provided with a pedal unit brake cylinder. The axle box spring uses rubber spring to replace steel spring, to save space and positioning device, the bearing uses a self-sealing cone roller bearing to replace cylinder roller bearing to prolong the maintenance period of the bearing, and the central traction uses rubber stack traction to save space, with better manufacturability and easy maintenance. The non-bolster air spring narrow-gauge cabin bogie eliminates bloster structure to reduce cost. And the basic brake uses pedal unit brake, with simple structure and high reliability.
Description
Technical field:
The utility model relates to railway passenger car bogie, especially relates to a kind of narrow gauge passenger train bogie truck.
Background technology:
Bogie truck is a passenger train traveling portion, and narrow gauge swing-bolster-free air spring bogie truck is a kind of bogie truck of special purpose, is applicable to the narrow gauge circuit.Bogie truck is made up of framework, axle-box positioning device, secondary suspension device and foundation brake rigging.Bogie truck is one of critical component of vehicle, and the performance of bogie truck plays important effect to vehicle.Whether the stationarity of vehicle operating, safety meet standard, depend primarily on the design of bogie truck.China does not have bogie of swing-bolster-free air spring narrow gauge passenger train, and external narrow gauge bogie truck ubiquity the shortcoming that running velocity is low, the stationarity safety is relatively poor, can't satisfy the operating needs of 100km/h.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of stationarity, the whole satisfactory 100km/h bogie of swing-bolster-free air spring narrow gauge passenger train of safety, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise framework, axle box, safe steel rope, levelling valve, air bellow, torsion bar spring, wheel, axletree, centre of pull pin, lateral damper, horizontal retaining, valve for pressure difference, the axle box rubber spring is set between truck side sill and the axle box, the axletree end is provided with self sealss circular cone roller bearing, be provided with the traction rubber metal pad between framework two crossbeams, the end of truck side sill is provided with the tread units brake cylinder.
The utility model journal box spring changes rubber spring into by steel spring, has saved space and registration device, and bearing changes self sealss circular cone roller bearing into by cylinder roller bearing, has prolonged the maintenance cycle of bearing.The rubber metal pad traction is adopted in central authorities' traction, has saved space, good manufacturability, easy to maintenance.The utility model does not have the bolster structure, has reduced cost.Foundation brake adopts the tread units braking, and is simple in structure, safe and reliable.Can satisfy the operating needs of various different line conditions and 100km/h fully by this bogie truck of parameter optimization.
