Through the setting of carriage 22, play the effect of support to slider 19, slider 19 and fan-shaped groove diapire can't contact avoid appearing the dead phenomenon of card in the rotation process simultaneously.
The working process is as follows: the vehicle is from right to left one-way traveling on the bridge, when the vehicle is out of control, can hit on the crashproof wall 2 of bridge, with the collision of a section of thick bamboo 7 and the first buffer structure of rotating on the crashproof wall 2, make and rotate a section of thick bamboo 7 and first buffer structure clockwise rotation, a section of thick bamboo 7 and first buffer structure take place to rotate and can produce a guide effect to the vehicle for the direction of the vehicle out of control is ajusted gradually and is kept away from crashproof wall 2, prevents that the vehicle from falling into under the bridge. When the vehicle collides with the rotating cylinder 7 and the first buffer structure, an extrusion is formed on the second buffer structure, so that the positioning frame 3 extrudes the rubber pad 6 and the pressure spring 5, and the pressure spring 5 is compressed to buffer the collision force of the vehicle.
The impact force of the vehicle collision is large, after the vehicle collides with the rotating cylinder 7 and the first buffering structure, the impact force generated by the vehicle collision is in rolling friction with the damping pad 12 of the first buffering structure and drives the outer cylinder 11 to rotate clockwise, and the outer cylinder 11 and the receiving piece 10 are fixedly connected and can also drive the damping structure in the receiving piece 10 to rotate together at the same speed. The clockwise rotation of the damping structure will drive the sealing push block 20 to rotate clockwise. Because the existence of sealed dog 21, it blocks the interval to have formed one between sealed ejector pad 20 and sealed dog 21, will extrude the damping oil between sealed ejector pad 20 and the sealed dog 21 when sealed ejector pad 20 clockwise turning, receive extruded damping oil will strike sealed ejector pad 20 and sealed dog 21, the impact force of damping oil is too big, will promote the rotation of four trapezoidal swash plates to open, and make second torsional spring 26 produce the torsional force, increase the velocity of flow of damping oil (decompose the power of sealed dog 21, avoid the impact force that the damping oil produced in the twinkling of an eye too big, lead to sealed dog 21 to get into the draw-in groove in advance. The extruded damping oil impacts the sealing push block 20 and the sealing stop 21 to generate a reverse blocking force, the sealing push block 20 drives the sliding block 19 to generate a reverse pulling force to stretch the tension spring 18 to a certain extent when acting on the tension spring 18, the rotation speed of the bearing part 10 is slowed down under the action of the reverse stretching force of the tension spring 18, the speed of the outer barrel 11 is reduced, namely the resistance of the damping oil plays a role in resisting balance through the sealing push block 20 and the tension spring 18 to the impact force of the vehicle, and the vehicle speed of the vehicle is reduced in an auxiliary mode.
However, due to the impact force of the vehicle, the sealing push block 20 is always in a clockwise rotation state, when the sealing push block 20 rotates to contact with the sealing stop block 21, the sealing push block 20 cannot rotate any more under the blocking of the sealing stop block 21, because of the impact force of the vehicle, other structures except the sealing push block 20 are still in a clockwise rotation state, the sealing push block 20 drives the slider 19 to stretch the tension spring 18 to the maximum extent, the tension spring 18 stretches to generate tension, the sealing stop block 21 has reverse blocking force on the sealing push block 20, the speed of the damping structure is reduced through the tension spring 18, and therefore the rotation speed of the outer cylinder 11 and the damping pad 12 is reduced, and the effect of assisting in reducing the vehicle speed is also achieved. When other structures except the sealing push block 20 rotate clockwise until the sliding block 19 contacts the end plate 15, the end plate 15 cannot move under the blocking of the sliding block 19, at this time, the collision force of the vehicle acts on the sealing stopper 21, so that the sealing stopper 21 rotates and drives the first torsion spring 23 to generate the torsion force, and the sealing stopper 21 enters the clamping groove 27. The blocking force of the sealing stopper 21 to the sealing push block 20 disappears, and the tension of the tension spring 18 is greater than the force of the damping oil to the sealing push block 20, so that the clockwise rotation speed of the sealing push block 20 is increased, and when the tension of the tension spring 18 is smaller and smaller, the speed of the sealing push block 20 is also gradually reduced. The force of the first torsion spring 23 will bring the sealing stop 21 back to the original state. When the tension of the tension spring 18 is balanced with the resistance of the damping oil, the first deceleration of the first buffer structure is completed. And also plays a role in assisting the reduction of the speed of the vehicle.
The plurality of damper mechanisms continue to rotate under the collision force of the vehicle, and start the next deceleration. The principle of deceleration is the same as the principle of first deceleration of the first buffer structure. A plurality of first buffer structure can circulate the shock attenuation, and the damage of buffer structure can hardly be caused in many times shock attenuation circulation.
When the speed of a vehicle of vehicle reduces to a definite value after a lot of speed reductions gradually, sealed ejector pad 20 also can reduce gradually the extrusion force of damping oil, when the extrusion force that damping oil received reduces gradually, the impact force of damping oil also can reduce gradually, when the certain degree that the impact force of damping oil reduces, the impact force of damping oil can't reach the condition that four trapezoidal swash plate rotations are opened, the space between the trapezoidal swash plate remains unchanged to guarantee the power that blocks of damping oil to sealed ejector pad 20 and sealed dog 21. After the vehicle speed is slow, the extrusion force of the sealing push block 20 to the damping oil is also reduced to be low, the sealing push block 20 is only subjected to the extrusion force of the damping oil to generate resistance, the rotating speed of the outer cylinder 11 is reduced through the tension spring 18, and the vehicle speed is continuously reduced and gradually tends to stop.
In other embodiments of the invention, the blocking structure may be provided without the tension spring 18. After the vehicle impacts the first buffer structure, the damping structure in the bearing piece 10 is driven to rotate at the same speed. The damping structure clockwise rotation can drive sealed ejector pad 20 clockwise rotation, only relies on sealed ejector pad 20 extrusion sealing oil between the ejector pad 20 and the sealed dog 21 when clockwise rotating, makes damping oil produce a reverse barrier force, and the resistance of damping oil plays the counteraction of a system balance through sealed ejector pad 20 to the impact of vehicle, and the speed of urceolus 11 reduces, realizes assisting the reduction to the speed of a motor vehicle of vehicle.
In other embodiments of the present invention, the sealing stopper 21 may be obliquely disposed in the damping oil chamber in an opposite direction to the flow direction of the damping oil. The phenomenon that the sealing stop block 21 enters the clamping groove in advance due to overlarge impact force generated by damping oil in the moment is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
