The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
To shown in Figure 5, a kind of without the intercity rail vehicle truck of bolster, be divided into two kinds of bogie trucks of motor-car and trailer as Fig. 1, be applied in the intercity motor train unit that satisfy 160 kilometers speed class.
Trailer bogie adopts H type framework structure, and framework comprises two crossbeams 1 and both sides curb girder 2, and the curb girder 2 of both sides is by two crossbeam 1 captive joints, at two crossbeams 1 of both sides curb girder 2 middle parts connections.Crossbeam 1 is the solid drawn pipe structure, curb girder 2 is body structure, and the curb girder 2 of both sides is passed at crossbeam 1 two ends, is welded and fixed on the interior lateral wall of curb girder 2, the two ends of crossbeam 1 are positioned at the outside of both sides curb girder 2, and the end at crossbeam 1 two ends is concordant with the lateral wall of curb girder 2 or protrude certain altitude.One of them crossbeam 1 is used for arranging anti-side rolling torsion rod, the steel disc that another crossbeam 1 is used at the port of end welded seal.
What the port at one of them crossbeam of two crossbeams 11 two ends was provided with anti-side rolling torsion rod turns round arm 8, is provided with the torsion bar 7 of anti-side rolling torsion rod in this crossbeam 1 inside, and torsion bar 7 runs through whole crossbeam 1.Be provided with the bolt block 10 of four protrusions at curb girder 2 near this crossbeam 1 surrounding, respectively arrange two about the port of crossbeam 1 end, the height of bolt block 10 will be higher than the height of crossbeam 1 end protrusion.1 end port place is provided with a supporting seat 11 at crossbeam, is provided with for bolt on supporting seat 11 and passes fixing through hole, and be used for the hole that torsion bar 7 passes.Supporting seat 11 is bolted on four bolt blocks 10 on crossbeam 1 port side, and torsion bar 7 passes the hole of the supporting seat 11 that fixes, two ends with turn round arm 8 by the transition splined, can be for convenience detach.Turn round arm 8 and rotate take torsion bar 7 as the center of circle, the other end of turning round arm 8 connects pipe link 9 by oscillating bearing, and the rotation of turning round arm 8 can make pipe link 9 above-below direction motions, other end connection body 17 bottoms of pipe link 9.
When car body 17 shakes, a velamen that is arranged in the pipe link 9 of both sides presses to lower motion, another root must be pulled upward, the power of two pipe link 9 different directions is through turning round the two ends that arm 8 is delivered to same torsion bar 7, torsion bar 7 produces reactive torque reduces the diff-H of two pipe links 9, reaches anti-effect of sidewindering.Because torsion bar 7 is arranged in crossbeam 1, actv. has been saved the inner space of bogie truck, has optimized the structure of bogie truck.Turn round the outside that arm 8 is arranged on both sides curb girder 2, the horizontal span that is arranged on curb girder 2 inboards than tradition is large, and the distance between two attachment points of car body 17 is also wide than traditional, the anti-side rolling torsion rod that is arranged on curb girder 2 inboards with tradition is compared, in the situation that identical reactive torque, because the distance between attachment point is large, what the amplitude that car body 17 rocks can be than with traditional anti-side rolling torsion rod is little, improve comfort level, and resisting the better effect of having used of sidewindering.
Be provided with the right single stage suspension of fifth wheel 3 at curb girder 2 two ends, single stage suspension 3 adopts the box location structures of tumbler shaft, and journal box spring adopts steel spring combination rubber damping mat structure, in whole of life without creep.
Wheel is to comprising the wheel 5 at solid axle 4 and solid axle 4 two ends, and solid axle 4 can satisfy the use of 160 kilometers intercity motor train unit of speed class, need not tubular axle 4 and comes expendable weight, has saved cost.Wheel 5 is whole wrought steel wheel, and diameter is 850-870mm, and optimum diameter is 860mm.Be provided with groove on the wheel rim of wheel 5 inside and outside both sides, be provided with noise reduction damping ring 12 in groove, for reducing the noise of vehicle.Be provided with secondary suspension 6 in the middle part of curb girder, secondary suspension 6 is Daqu capsule air bellow, and effective diameter is 520-540mm, and optimum value is 530mm, Daqu capsule air bellow connection body 17 bottoms and bogie truck.Being used in conjunction with of anti-side rolling torsion rod and Daqu capsule air bellow, the shortcoming that makes Daqu capsule air bellow that car body 17 is inclined to roll the angle to increase is made up, and has improved the stationarity of vehicle.
Because the torsion bar 7 of anti-side rolling torsion rod is arranged on crossbeam 1 inside, and turns round arm 8 and be arranged on curb girder 2 outsides, trailer bogie between both sides curb girder 2, and crossbeam 1 and wheel between, all had enough spaces, other members of bogie truck can be set.The wheel to and crossbeam 1 between be provided with two reel caliper brake (not shown)s, the reel caliper brake is arranged on crossbeam 1, reel is arranged on solid axle 4.
Be provided with the drawing pull bar seat on crossbeam 1, be provided with drawing pull bar between two crossbeams 1, drawing pull bar one end connects center pin 13, and the other end is arranged on the drawing pull bar seat, and center pin 13 is captiveed joint with car body 17 bottoms.
Motor car bogie is with respect to trailer bogie, except including above-mentioned feature, also is provided with traction drive mechanism.Because the torsion bar 7 of anti-side rolling torsion rod is arranged on crossbeam 1 inside, and turns round arm 8 and be arranged on curb girder 2 outsides, make to have had enough spatial placement traction drive mechanisms between both sides curb girder 2, and wheel disc caliper brake and wheel tread clearing apparatus.
Crossbeam 1 and the wheel between be provided with a traction drive, traction drive comprises traction electric machine 14 and gear case 15, gear case is set on solid axle 4.Traction electric machine 14 is connected by tooth-like adaptor union with gear case 15, and tooth-like adaptor union is strong at the displacement capabilities of radial-axial, can be applicable to the in-use performance of intercity guideway vehicle.Gear clusters in gear case 15 press-fit with solid axle 4 on.Due to the position of trailer coupling 14, the reel caliper brake can't be set, so be provided with wheel disc caliper brake 16 and wheel tread clearing apparatus between wheel 5 and crossbeam 1.Wheel disc caliper brake 16 is arranged on crossbeam, is provided with the wheel tread clearing apparatus above wheel disc caliper brake 16.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solution of the present invention,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present invention.
