Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a single-arm double-connecting-rod anti-rolling torsion bar tilting device.
Background
The high speed and comfort are the development trend of rail vehicles, but due to the limitation of line conditions, such as the characteristics of large quantity of curve segments, more small-radius curves and the like, the unbalanced centrifugal force of the vehicle in the turning process can be increased by simply increasing the running speed of the vehicle, and the comfort of passengers and the safety and stability of the vehicle are influenced. Considering the factors of high cost, high maintenance cost, high technical requirements and the like of the construction of a high-speed railway, the vehicle is expected to be transformed on the existing railway, so that the aim of improving the running speed of the vehicle is fulfilled.
The pendulum train is an effective technical measure for accelerating the speed of the existing line, and the action principle is shown in figure 1. The method is characterized in that when a vehicle enters a curve section, line information is measured by a detection system, and the line information is transmitted to a control system to calculate an inclination angle which needs to be additionally generated by the vehicle body, namely an additional super-high is added, so that the centripetal force is increased, most of the over-speed centrifugal force is balanced, the train can stably pass through the curve at a high speed, the centrifugal force felt by passengers is greatly reduced, and the riding comfort is obviously improved.
The anti-rolling torsion bar has the working principle that when the left spring and the right spring are displaced vertically in opposite directions (namely, when the vehicle body rolls laterally), two horizontally arranged torsion arms respectively have the effect of a force and a moment in opposite directions on the torsion bar, so that the elastic torsion bar bears the torque to generate torsional elastic deformation and plays the role of the torsion bar spring, and the counter moment of the torsion bar spring is always opposite to the direction of the lateral rolling displacement generated by the vehicle body so as to restrain the lateral rolling vibration of the vehicle body. However, when the left spring and the right spring are displaced vertically in the same direction, because the two ends of the torsion bar are supported by the rotating shaft and the bearing, the left torsion bar and the right torsion bar only rotate in the same direction, and the torsion bar spring action is not generated, so the anti-rolling action is not generated on the vehicle body.
For a vehicle supported by two points, the anti-rolling torsion bar has higher rigidity, and if other tilting modes are adopted, the anti-rolling torsion bar can generate larger moment resistance to block the vehicle body from tilting, so that the actuator is larger and even exceeds the maximum limit values of the bearing capacity and the strength of other parts.
In order to solve the problem, a roll-resistant torsion bar tilting device is proposed in the industry, and as shown in fig. 2, the device is provided with an actuator by modifying a connecting rod, and the vehicle body is tilted by stretching and contracting the actuator. However, once the actuator fails, the whole connecting rod is in a free telescopic state, so that the tilting function is completely failed, the normal straight running of the vehicle is affected, the running safety of the vehicle is seriously affected, and great potential safety hazards exist.

The single-arm double-connecting-rod anti-rolling torsion bar tilting device is controlled by a control system of a train, and can realize the tilting of a train body in the process from the train entering a transition curve to the train exiting a curve.
In a specific example, the servo valve is integrated on the hydraulic cylinder, and the hydraulic cylinder electrohydraulic servo system is formed by the servo valve and the hydraulic pump system. The servo valve can specifically select corresponding single-way and multi-way electromagnetic valves and other valve bodies according to requirements. Fig. 6 is a control schematic diagram of an electro-hydraulic servo system of a hydraulic cylinder provided in an embodiment of the present invention. In the example shown in fig. 6, a vehicle has two bogies, two sets of single-arm double-link anti-roll torsion bar tilting devices, and four hydraulic cylinders share one set of hydraulic pump system.
The figure includes: the hydraulic system comprises a hydraulic pump system 100, a hydraulic cylinder 200-1, a hydraulic cylinder 200-2, a hydraulic cylinder 200-3 and a hydraulic cylinder 200-4; the hydraulic control system comprises an oil tank 1, a filter 2, a motor 3, a hydraulic pump 4, a stop valve 5, a one-way valve 6, a pressure sensor 7, an energy accumulator 8, a filter 9, an overflow valve 10, a two-position two-way electromagnetic valve 11, a three-position four-way electromagnetic valve 12, a two-position two-way electromagnetic valve 13, an overflow valve 14 and a hydraulic cylinder 15.
The working principle of the present invention will be explained with reference to fig. 3 to 6. It should be noted that the control principle shown in fig. 6 is a specific technical implementation application, which is only an example and is not intended to limit the present invention, and any technical implementation that controls the extension or contraction of the actuator link according to the control command of the control system and drives the torsion bar to twist to implement the vehicle body tilting based on the design structure of the single-arm double-link anti-roll torsion bar tilting device of the present invention is within the technical scope of the present invention.
In this example, taking the process of the vehicle entering the easement curve from straight as an example:
in the running process of the train, the detection system arranged on the train can detect various running state parameters of the train in real time and send the running state parameters to the control system to judge the running state.
In the case where it is determined that the vehicle is traveling in a straight line, the cylinder upper and lower chambers 441 and 442 are communicated with each other by the normally open two-position, two-way solenoid valve 13. When the vehicle does not need to tilt, the two-position two-way electromagnetic valve 13 is normally open, the three-position four-way electromagnetic valve 12 is normally closed at the position b, and the piston rod 1043 freely moves in the cylinder 1044 at the moment. Meanwhile, because the two ends of the hydraulic cylinder connecting rod are connected through spherical hinges, free rotation in all directions can be achieved, and acting force is not applied to the torsion arm by the hydraulic cylinder connecting rod at the moment.
When the vehicle body is judged to enter the relaxation curve, the control system generates a control signal, the two-position two-way electromagnetic valve 13 is closed, the three-position four-way electromagnetic valve 12 of the vehicle body on the inner side of the curve is switched to the a position, the oil is fed into the lower oil cavity 442, the oil is fed into the upper oil cavity 441, and the piston rod 1043 on the side is extended; the three-position four-way electromagnetic valve 12 of the vehicle body at one side of the outer side of the curve is opened to the position c, oil is fed into the upper oil cavity 441, and oil is fed into the lower oil cavity 442, so that the piston rod 1043 at the side is contracted; this causes torsion bar 101 to twist, thereby realizing a vehicle body tilting motion.
When it is determined that the vehicle body enters the easement curve from the curve section, that is, the vehicle body needs to be returned from the tilted state to the horizontal state. At the moment, the control system generates a control signal, the two-position two-way electromagnetic valve 13 keeps a closed state, the three-position four-way electromagnetic valve 12 of the vehicle body at the inner side of the curve is opened to the position c, the upper oil cavity 441 is filled with oil, and the lower oil cavity 442 is filled with oil, so that the piston rod 1043 at the side is contracted; the three-position four-way electromagnetic valve 12 of the vehicle body at one side of the outer side of the curve is turned to a position a, the lower oil cavity 442 is filled with oil, and the upper oil cavity 441 is filled with oil, so that the piston rod 1043 at the side is extended; thereby, the torsion bar 101 is restored, and the vehicle body is restored from the tilt state to the horizontal state.
When the vehicle is judged to enter the straight line again, the control system generates a control signal at the moment, the two-position two-way electromagnetic valve 13 enters the normally open position, and the three-position four-way electromagnetic valve 12 enters the normally closed position.
In addition, the design of overflow valve 14 is used for guaranteeing the automatic pressure release under the too high oil pressure, avoids damaging the pneumatic cylinder.
That is, when the vehicle body runs linearly, the piston rod can move up and down freely by controlling the low-pressure communication of the upper cavity and the lower cavity of the hydraulic cylinder, and the anti-rolling torsion bar keeps the original performance. When the vehicle enters a relaxation curve, the servo valve is controlled to charge oil to the upper cavity of the hydraulic cylinder on the outer side of the curve to shrink the piston rod, and charge oil to the lower cavity of the hydraulic cylinder on the inner side of the curve to extend the piston rod, so that the two torsion arms are driven to rotate around the first spherical hinge connecting node respectively to drive the torsion bar to twist, and the vehicle body tilts and swings.
Compared with the common scheme in the prior art, the single-arm double-connecting-rod anti-rolling torsion bar tilting device only loses the tilting function even if the actuator fails, the adjustable connecting rod still plays the normal role, and the vehicle can still safely and normally run in a straight line and at a higher speed curve.
According to the single-arm double-connecting-rod anti-rolling torsion bar tilting device provided by the embodiment of the invention, the adjustable connecting rod and the actuator connecting rod are separately arranged through the connection of the torsion arms, so that the anti-rolling torsion bar tilting device can realize the tilting action of a vehicle body, and meanwhile, the safety and reliability are greatly improved.
