Abstract
The utility model relates to a swing bolster device, which comprises a swing bolster body. The swing bolster body consists of a U-shaped box composed of an outer side plate, an upper cover plate, an inner side plate and a lower cover plate in a welded manner, hoisting seats, draw bar seats, air spring connectors, a rotary support seat, a transverse stopping seat, swing stopping seats and shock absorber seats are arranged on the swing bolster body, and the different seats are arranged transversely relative to the center of the swing bolster. The swing bolster device is simple in structure, small in deformation and high in strength, while fatigue life of the swing bolster is prolonged and maintenance cost for running of vehicles is reduced. Further, the swing bolster device can be used for connecting a bogie structure with a vehicle body and can bear and transmit vertical force, transverse force and longitudinal force, meanwhile fatigue strength and rigidity of the swing bolster are increased, dynamic performance of the vehicle is improved, and stability, reliability and safety of a bogie when in running of the vehicle are improved.
Description
Technical field
The utility model relates to a kind of used for rail vehicle bogie truck connecting device, is specifically related to the bolster device that a kind of rail vehicle truck framework connects car body.
Background technology
Bolster is the connecting device between city rail vehicle car body and the truck frame, mainly bears and transmit vertical force, transverse force and longitudinal force.Existing city rail vehicle bolster mainly bears and transmits vertical force and longitudinal force between car body and bogie truck by steel plates such as upper cover plate, lower cover, side plate, each bearing box-structure that is welded.But the bolster complex structure of this structure, insufficient rigidity, the poor stability of vehicle deforms and fracture by fatigue easily, vehicle operation maintenance cost height.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, and a kind of simple in structure, intensity good, reliability is high, distortion is little and the fatigue crack-resistant ability is strong bolster device is provided.
Bolster device of the present utility model comprises the bolster body that the U-shaped casing that is welded into by outer panel, upper cover plate, interior plate and lower cover constitutes, it is characterized in that described bolster body has been provided with flap seat, drawing pull bar seat, air spring attaching parts, pivoting support seat, horizontal stopping seat, shake the head stopping seat and damper base, each mount pad is opposed with respect to the bolster central cross.
In order better to realize above-mentioned purpose, described air spring attaching parts is a fourth shape rod member, is provided with air extractor vent and air spring admission port.
Described drawing pull bar seat is provided with the levelling valve mounting flange.
It is the vertical damper device that described damper base is provided with two.
Described pivoting support seat is provided with rotary supporting device.
The fatigue life that bolster apparatus structure of the present utility model is simple, distortion is little, intensity is high, improved bolster, reduced the operation and maintenance cost of vehicle.The interconnect function of truck frame and car body be can not only realize, vertical force, transverse force and longitudinal force born and transmit; And can improve bolster strength at repeated alternation and bolster rigidity, improve the dynamic performance of vehicle.The stability of bogie truck, reliability and safety when having improved vehicle operating.

Among the figure 1, play flap seat, 2, the drawing pull bar seat, 3, the bolster body, 4, air spring attaching parts, 5, the pivoting support seat, 6, horizontal stopping seat, 7, the stopping seat of shaking the head, 8, damper base, 9, air extractor vent, 10, outer panel, 11, upper cover plate, 12, interior plate, 13, lower cover.
The specific embodiment
Bolster device of the present utility model comprises the bolster body 3 that the U-shaped casing that is welded into by outer panel 10, upper cover plate 11, interior plate 12 and lower cover 13 constitutes, bolster body 3 is provided with 4 and plays 2,2 air spring attaching partss 4 of 1,4 drawing pull bar seats of flap seat, pivoting support seat 5, horizontal shake the head stopping seat 7 and 4 damper bases 8 of 6,4 of stopping seats, and each mount pad is opposed with respect to the bolster central cross.This makes the bolster barycenter near the geometric centre of bogie truck, reduces the rotor inertia that shakes the head of bogie truck, can improve the stability of vehicle like this, reduces the wheel-rail lateral force of straight line and sweeping curve operation.Laterally stopping seat 6 is used for installing lateral damper and horizontal backstop.
Air spring attaching parts 4 is a fourth shape rod member, is provided with air extractor vent 9 and air spring admission port.
Drawing pull bar seat 2 is provided with the levelling valve mounting flange; It is the vertical damper device that damper base 8 is provided with two; Pivoting support seat 5 is provided with rotary supporting device.The draw bar that is positioned on the drawing pull bar seat 2 is provided with rubber arthrosis, and by leading the rubber arthrosis longitudinal vibration that decays, this rubber arthrosis can adapt to relatively rotating between truck frame and the bolster.
