Abstract

The utility model relates to an anti lateral rolling twisted bar installed on the train bogie, in particular to an anti lateral rolling twisted bar used in the high speed train, and belongs to the railway vehicle bogie field, the utility model technology measure is to provide a sealing sleeve between the shoulder of the torque arm and the end surface of the fulcrum bearing, so as to prevent the dust and sundries from easily intruding. The utility model has the advantages of novel and reasonable structure and design, good safety performance, long service life.

Description

Anti-side rolling torsion rod

The utility model relates to the anti-side rolling torsion rod that uses on the torsion bar of the anti-side rolling of installing on the train bogie truck, particularly high speed train, belongs to the field of bogies for railway vehicles.

Along with air bellow being extensive use of ON TRAINS, the vibration performance of the vertical direction of train has been had preferably improve, improved the stationarity of train operation.But because air bellow is very soft, also reduced the rigidity of sidewindering of vehicle, sidewinder after rigidity reduces, can make high speed train when passing through track switch or do the curve operation, the angle of roll of car body strengthens, and particularly the center of gravity of double deck passenger car is higher, and the angle of roll can be bigger, make the people produce a kind of to overturn rock sensation, also limited the speed of a motor vehicle and further improved.In order to improve the speed of train, must when using air bellow, also to improve the rigidity of sidewindering of car body, method commonly used is exactly to install torsion bar mechanism for preventing side rolling of train carriage additional in the suspension of bogie truck, utilizes the torsion of torsion bar to improve anti-rigidity of sidewindering.Torsion bar mechanism for preventing side rolling of train carriage mainly is by a torsion bar, two " Z " fonts are turned round arm and two connecting rods compositions, on the member of small end above connecting rod base is installed in spring, the connecting rod lower end is turned round arm through oscillating bearing with " Z " font and is connected, the other end that " Z " font is turned round arm is installed on the torsion bar on the member of torsion bar two ends below supporting base is installed in spring with the circular cone spline, when train generation side direction is rocked, a connecting rod that is installed in two connecting rods of car body both sides is moved downward by pressure, another root connecting rod is inevitable to be drawn and upward movement, the power of the different directions on two connecting rods passes to two of same torsion bar through turning round arm, make torsion bar with the moment of torsion that produces when rocking of car body, because of producing reactive torque, the elasticity of torsion effect of torsion bar makes car body pass on moving angle to reduce, promptly sidewinder angle and reduce, reach anti-effect of sidewindering.But the anti-side rolling torsion rod that uses at present obviously exists the weight of torsion bar big, low, the easy generation resonance of the natural frequency of vibration and fracture by fatigue and connecting rod are welded type, shortcomings such as weld seam easy fracture.

The patent No. is that 98226425.9 utility model patent " high speed train novel anti side rolling torsion rod " discloses a kind of weak point that can overcome existing anti-side rolling torsion rod, adapt to high speed train needs in light weight, the natural frequency of vibration is high, mechanical strength is high and connecting rod does not have the high speed train novel anti side rolling torsion rod that bullet stitches, technical scheme is to change solid torsion bar into high strength alloy steel hollow torsion bar, torsion bar is connected with the circular cone invoice serration that is connected to of turning round arm, and changing the welded type connecting rod is the solid die forging.But because the torsion bar work under bad environment causes getting rusty of bearing and other threaded connection place easily, cause rotation dumb, because bearing and supporting base are free-running fit, when dust and other impurities was invaded, dismounting was difficult during dismounting.

The purpose of this utility model is to propose a kind of rotation anti-side rolling torsion rod flexibly.

Technical measures of the present utility model are that a sealing shroud is set between the end face of the shoulder of turning round arm and supporting base, make dust and foreign material be difficult for invading.

Another technical measures of the present utility model are that sealing shroud is made up of two parts, and a part is a metal piece, and another part is a Rubber Parts.

The utility model has the advantages that structure design is new reasonable, safety performance good, long service life.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is an another kind of structural representation of the present utility model.

Anti-side rolling torsion rod as shown in Figure 1 and Figure 2, comprise torsion bar 1, supporting base 2, turn round arm 3, connecting rod 4, connecting rod base 5 and oscillating bearing 6,8 of end faces at the shoulder 7 of turning round arm 3 and supporting base 2 are provided with sealing element 9, and sealing element 9 is a sealing shroud, and sealing shroud is made up of rubber.

As Fig. 1, anti-side rolling torsion rod shown in Figure 3, sealing element 9 is made up of two parts, and a part is a metal piece 10, and another part is a Rubber Parts 11.Can cushion the axially loaded of turning round arm 3 better.
