Abstract
The utility model relates to an active vibration controlled steering rack for railroad cars, which comprises a bogie frame, a vertical vibration sensor for vehicles, a transverse vibration sensor for vehicles and a controlling device. The utility model is characterized in that the bogie frames are connected with a vehicle by an air spring, and a hydraulic damper is connected between a left bogie frame and a right bogie frame; the air spring is provided with an air inlet pipe which is connected with an electromagnetic valve, and the air spring is also provided with a gas discharge tube; a plunger is arranged in the hydraulic damper, oil pipes are arranged on an inner casing of the hydraulic damper at both sides of the plunger, and the two oil pipes are connected with a reversal valve which is connected with an oil hydraulic cylinder. The utility model has the advantage of active control of the vibration of vehicles to a bogie frame of railway vehicles.
Description
The utility model relates to a kind of bogies for railway vehicles, and particularly a kind of rolling stock is initiatively controlled the bogie truck that shakes.
At present general bogies for railway vehicles employing keeps away the spring that shakes and comes vibration damping, but continuous speed-raising along with train, vehicle can shake, jolt owing to the problem of roadbed or bend, track switch, therefore cause the damage of vehicle part, simultaneously owing to rock, jolt and acutely can cause vehicle to overturn and the major accident of damaged line.
The purpose of this utility model provide a kind of can be to the bogie of car of rolling stock ACTIVE CONTROL vibration.
The technical solution of the utility model is that a kind of rolling stock of design is initiatively controlled the bogie truck that shakes, comprise bogie truck, vehicle vertical shake sensor, the lateral direction of car vibration sensor, control setup, it is characterized in that: bogie truck is connected by air bellow with vehicle, there is hydraulic damper to connect between about bogie truck, air inlet pipe is arranged on the air bellow, air inlet pipe connects electromagnetic valve, electromagnetic valve meets gas-accumulating tank and distributing valve and inlet manifold, discharging air pipe is arranged on the air bellow in addition, and discharging air pipe connects distributing valve, the distributing valve air valve that runs in, piston is arranged in the hydraulic damper, be connected to oil pipe on the hydraulic damper inner casing of piston both sides, two oil pipes connect change-over valve, and change-over valve connects oil hydraulic cylinder.
The utility model has the advantages that and to carry out the ACTIVE CONTROL vibration of vehicle to the bogie truck of rolling stock.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing 1 is a bogie structure scheme drawing of the present utility model,
Accompanying drawing 2 is an oil gas connection structure scheme drawing of the present utility model,
Comprise bogie truck 1 among the figure, vehicle vertical shake sensor 2, lateral direction of car vibration sensor 3, control setup 4, it is characterized in that: bogie truck 1 has air bellow 5 to be connected with vehicle, there is hydraulic damper 6 to connect between the left and right sides bogie truck 1, air inlet pipe 7 is arranged on the air bellow 5, air inlet pipe 7 connects electromagnetic valve 8, electromagnetic valve 8 gas-accumulating tanks 10 and distributing valve 11 and inlet manifold 9, discharging air pipe 12 is arranged on the air bellow 5 in addition, discharging air pipe 12 connects electromagnetic valve 18, electromagnetic valve 18 connects distributing valve 11, distributing valve 11 air valve 13 that runs in, piston 20 is arranged in the hydraulic damper 6, be connected to oil pipe 14 on hydraulic damper 6 inner casings 21 of piston 20 both sides, 17, two oil pipes 14,17 connect change-over valve 15, and change-over valve 15 connects oil hydraulic cylinder 16.
When high vehicle speeds, because roadbed or bend, track switches etc. cause that vehicle rocks, when jolting, vehicle vertical shake sensor 2, lateral direction of car vibration sensor 3 detects the data that lateral direction of car rocks and pitches, computing through control setup 4, calculate the descriscent mental and physical efforts of vehicle, data such as transverse force and vertical power, decompose the back Comprehensive Control by power of pitching and transverse force respectively, to the vehicle power that pitches, 5 venting of 18 pairs of air bellows of control setup 4 control electromagnetic valve, to slow down the impulse force that vehicle up jolts, when vehicle down jolts, 8 pairs of air bellows 5 of control setup 4 control electromagnetic valve are calmed the anger, to slow down the impulse force that vehicle down jolts, the gas of emitting can be stored in the gas-accumulating tank 10, and distributing valve 11 and blow off valve 13 can balanced inlet manifold 9 enter gas-accumulating tank 10, the air pressure of air bellow 5.When vehicle was desired to rock toward a side, the oil pipe 14 of control setup 4 control linkage hydraulic dampers 6 and the change-over valve 15 of oil pipe 17 were regulated the side-to-side movement of hydraulic damper 6 inner carriers 20, desire toward side rolling power with the payment vehicle.Because vehicle rocks, offset the rocking of vehicle, pitch force by controlled air bellow 5 and hydraulic damper 6 when jolting, and is therefore very steady when high vehicle speeds, guarantees the safety that train is run at high speed.
