Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the liquid damper with damping force jumping suddenly with displacement according to the present invention includes a damper housing 11, an end cap a12 and an end cap B13 fixedly installed at the left and right ends of the damper housing 11, a low damping piston 2 slidably installed inside the damper housing 11, and a piston rod 21 having one end fixedly connected to the low damping piston 2 and the other end extending to the outside of the end cap B13.
Damping fluid is filled in a closed space formed by the damper shell 11, the end cover A12 and the end cover B13; the low-damping piston 2 is provided with a throttling port C20 for allowing damping fluid to flow; the left side and the right side of the low-damping piston 2 are respectively provided with a left dynamic damping mutation device and a right dynamic damping mutation device.
The left-hand damping mutation device comprises a gear bracket A31 fixedly arranged on the lower middle part of the left side of the low-damping piston 2 along the horizontal direction, a duplicate gear A32 rotatably arranged on the left end of the gear bracket A31, a fixed rack A33 with two ends respectively connected with an end cover A12 and an end cover B13 and arranged along the horizontal direction, a high-damping piston A35 arranged on the left side of the duplicate gear A32 and capable of sliding left and right relative to the damper shell 11, and a translation rack A34 fixedly arranged on the right side of the high-damping piston A35 along the horizontal direction; a group of throttling ports A351 with the same inner diameter are formed in the high-damping piston A35; the translational rack A34 and the fixed rack A33 are respectively positioned at the upper side and the lower side of the gear support A31.
The right dynamic damping mutation device comprises a gear bracket B41 fixedly arranged on the upper part of the middle part of the right side of the low damping piston 2 along the horizontal direction, a duplicate gear B42 rotatably arranged on the right end of the gear bracket B41, a fixed rack B43 with two ends respectively connected with an end cover A12 and an end cover B13 and arranged along the horizontal direction, a high damping piston B45 arranged on the right side of the duplicate gear B42 and capable of sliding left and right relative to the damper shell 11, and a translational rack B44 fixedly arranged on the left side of the high damping piston B45 along the horizontal direction; a group of throttling ports B451 with the same inner diameter is arranged on the high-damping piston B45; the fixed rack B43 and the flat rack B44 are respectively positioned at the upper side and the lower side of the gear bracket B41. The fixed rack a33 and the fixed rack B43 each pass through the high damping piston a35, the high damping piston B45, and the low damping piston 2 at respective locations, and the piston rod 21 passes through the high damping piston B45 at respective locations.
The duplex gear B42 has the same structure as the duplex gear A32 and consists of a small-diameter complete gear and a large-diameter incomplete gear which coaxially rotate synchronously; the radius of the large-diameter incomplete gear is equal to twice the radius of the small-diameter complete gear, so that when the large-diameter incomplete gear in the duplicate gear A32 or the large-diameter incomplete gear in the duplicate gear B42 is in a meshed state, the movement speed of the high-damping piston A35 or the high-damping piston B45 is equal to three times the movement speed of the low-damping piston 2.
A small-diameter complete gear in the duplicate gear A32 is always meshed with the fixed rack A33, and a small-diameter complete gear in the duplicate gear B42 is always meshed with the fixed rack B43; the large-diameter incomplete gear in the duplicate gear A32 can be meshed with the translation rack A34 in a time sharing mode, and the large-diameter incomplete gear in the duplicate gear B42 can be meshed with the translation rack B44 in a time sharing mode.
The outer diameter of the low damping piston 2 is equal to the outer diameter of the high damping piston A35 and the outer diameter of the high damping piston B45, and is equal to the inner diameter of the damper shell 11; the orifices A351, the orifices B451 and the orifices C20 are equal in hole diameter and number, so that the damping forces of the low-damping piston 2, the high-damping piston A35 and the high-damping piston B45 are guaranteed to have constant damping force at equal movement speed, namely the ratio of the damping force of the high-damping piston A35 and the high-damping piston B45 to the damping force of the low-damping piston 2 is equal to the ratio of the movement speeds of the high-damping piston A35 and the high-damping piston B45 to the movement speeds of the low-damping piston 2.
The working principle of the invention is as follows: referring to the description of fig. 1 and 3, it is first assumed that the low damping piston 2 is in a static equilibrium state, i.e., the low damping piston 2 is located at the middle between the high damping piston a35 and the high damping piston B45. It is not assumed that the piston rod 21 is forced leftward.
The first stage is as follows: the low damping piston 2 moves leftwards and gradually deviates from the static balance position, and the deviation distance is less than x0. In this stage, the piston rod 21 pushes the low damping piston 2 to move leftward, the small-diameter full gear in the double gear a32 rolls leftward along the fixed rack a33, and the large-diameter non-full gear in the double gear a32 is disengaged from the translational rack a 34. Therefore, the high damping piston A35 and the high damping piston B45 are static, only the low damping piston 2 slides leftwards, the damping fluid flows through the throttling port C20 formed in the low damping piston 2, the damping force is generated only by the movement of the low damping piston 2, namely the damping force F borne by the piston rod0。
And a second stage: the low-damping piston 2 continuously moves leftwards and gradually deviates from the static balance position, and the deviation distance is greater than x0Less than 2x0. In this stage, the large diameter incomplete gear in the dual gear a32 is in meshing transmission with the translation rack a 34. Therefore, the leftward movement of the low-damping piston 2 inevitably pushes the high-damping piston a35 to move leftward rapidly, and the leftward movement speed of the high-damping piston a35 is three times of the movement speed of the low-damping piston 2, so that the damping force applied to the piston rod 21 during the displacement suddenly jumps to 4F0。
And a third stage: the low damping piston 2 moves rightwards to gradually approach a static equilibrium position, and the deviation distance is more than x0Less than 2x0. In this stage, as the piston rod 21 moves to the right, the gear bracket a31 pulls the duplicate gear a32 to roll clockwise, the large-diameter incomplete gear in the duplicate gear a32 is in meshing transmission with the translation rack a34, so that the high-damping piston a35 is pulled to move to the right, and the speed of the high-damping piston a35 is three times of the speed of the low-damping piston 2. Therefore, the damping force applied to the piston rod 21 during this displacement is still 4F0。
A fourth stage: the low-damping piston 2 moves rightwards to gradually approach a static balance position, and the deviation distance is less than x0. In this stage, as the piston rod 21 continues to move to the right, the large diameter imperfect gear of the double gear a32 disengages from the translational rack a34, so the high damping piston a35 is stationary although the low damping piston 2 is moving to the right. Therefore, the piston rod 21 receives a damping force F0。
The working principle of the piston rod 21 being forced to the right so that it moves to the right away from the equilibrium position is the same as above. Therefore, the damping force kick stage still exists with the left-right movement of the piston rod 21.
As shown in fig. 3, the relationship curve of the damping force and the displacement of the present invention satisfies the following relationship: when the distance of the low damping piston 2 deviated from the balance position is less than x0The damping force of the system is F0(ii) a When the distance of the low damping piston 2 deviated from the balance position is more than x0The damping force of the system is 4F0。
The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through creative efforts should fall within the scope of the present invention.
