Abstract
The utility model discloses an anti-rolling torsion bar device of a passenger car, which comprises a torsion bar, torsion arms, supporting seats and connecting rods, wherein both ends of the torsion bar are respectively connected with one torsion arm, the outer sides of the torsion arms are provided with the supporting seats, the torsion arms are connected with the connecting rods, the connecting rods are also connected with connecting rod seats, the torsion bar is sleeved with a torsion bar sleeve, and the torsion arms are sleeved with torsion arm sleeves. The utility model has the advantages that the device has a novel and reasonable structural design, good safety performance and long service life, and is convenient to assemble and disassemble.
Description
Technical field
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 passenger car bogie, particularly high speed train, belongs to the field of bogies for railway vehicles.
Background technology
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 degree of cutting to pieces that sidewinders 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, particularly the center of gravity of double deck passenger car is higher, 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, the method that adopts is exactly to install torsion bar mechanism for preventing side rolling of train carriage additional in the suspension of bogie truck usually.The torsion that stalk is turned round in utilization improves 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 structure of the upper end of connecting rod 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 with the circular cone spline, when train generation side direction rock right, 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, the elasticity of torsion effect of garden torsion bar and produce the angle that reactive torque makes car body change telemechanical and reduce is promptly sidewindered angle and is reduced.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 01217561.7, the applying date is 2001.2.26, publication number is 2464593 utility model patent, " rail vehicle anti-side rolling torsion rod " discloses the torsion bar of the anti-side rolling of installing on a kind of train bogie truck, the anti-side rolling torsion rod that uses on the high speed train particularly, the field that belongs to bogies for railway vehicles, the technical measures of this patented technology are the end caps that can dismantle of supporting base end design that will be one originally, and design a pouring orifice, make the bearing lubrication in the supporting base abundant, convenient disassembly.But because the torsion bar work under bad environment, corrosion easily causes rotation dumb, and, end cap also might in use come off, and will cause very serious consequence, moreover, because bearing and supporting base are free-running fit, when dust and other impurities was invaded, dismounting was difficult during dismounting.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of structure design new reasonable, installing/dismounting
Convenient, safety performance is good, the passenger vehicle anti-side rolling torsion rod of long service life.
For realizing above-mentioned technical purpose, the technical solution of the utility model is:
The passenger vehicle torsion bar mechanism for preventing side rolling of train carriage comprises torsion bar, turns round arm, supporting base and connecting rod that the torsion bar two ends connect respectively turns round arm, the outside of turning round arm is provided with supporting base, turn round arm is connected with connecting rod, also be connected with connecting rod base on the connecting rod, be socketed with the torsion bar cover on the described torsion bar, turn round to be socketed with on the arm and turn round the arm cover.
Also be welded with adjusting pad on the described supporting base.
Also comprise the bearing pin that connects connecting rod and connecting rod base, be provided with screw plug, also be provided with flange and packing ring on the described bearing pin in the end of connecting rod base.
Advantage of the present utility model is:
Owing to be provided with the torsion bar cover on the arm and turn round the arm cover at torsion bar and turning round, can inject grease during for cavity at torsion bar, seal the torsion bar cover then, as long as the torsion bar cover is not bad, so, the work of whole torsion bar system just can not be affected.
Secondly, be provided with and turn round the arm cover, also can play a very good protection turning round arm.
The 3rd, adjusting pad is set, can adjust supporting base at any time, make installation seem and be more prone to, and, in use for some time, because, system's displacement, adjusting pad will play good regulating action.
The 4th, bearing pin is set, dismounting connecting rod and connecting rod base that can be convenient can help maintenance like this.
