Description

Technical Field

[0001] The present invention relates to the technical field of shock absorbers, and in particular to a high dynamic response electromagnetic shock absorption system. Background Art

[0002] Existing hydraulic shock absorbers rely primarily on three approaches for damping adjustment: Fixed orifice: Orifices of varying diameters are pre-machined into the piston or base valve, with a mechanical dial or slide valve switching between several apertures. This approach offers only two to four discrete settings, and once the aperture is machined, it cannot be dynamically fine-tuned. Stacked valve disc: Multiple layers of thin springs are sequentially opened under varying pressure differentials to create three damping levels: soft, medium, and hard. While relatively smooth in the low- and mid-frequency ranges, the threshold rises after spring fatigue, leading to misaligned damping levels. Furthermore, the valve discs open passively in response to flow, preventing active driver or controller selection. Overall, existing technologies generally suffer from a limited number of settings, failing to meet the urgent need for multiple settings and continuous damping under high-speed or complex operating conditions.

DETAILED DESCRIPTION

[0028] A sealing drive electromagnet 107 is fixedly mounted at the bottom of the inner cylinder 103. A sealing magnetic ring 106 is magnetically coupled below the sealing drive electromagnet 107. The sealing magnetic ring 106 is slidably mounted on the inner wall of the bottom sealing cover 105. The sealing magnetic ring 106 provides a sliding, sealed engagement between the circumferential surface of the sealing drive electromagnet 107 and the inner wall of the bottom sealing cover 105. The sealing magnetic ring 106 is used to seal the flow damping adjustable tube 109 from the flow space between the outer cylinder 101 and the inner cylinder 103. A tension spring 108 is fixedly mounted between the sealing magnetic ring 106 and the bottom surface of the inner wall of the bottom sealing cover 105. The tension spring 108 is used to pull the sealing magnetic ring 106 in a direction away from the sealing drive electromagnet 107. The tension spring 108 is disposed around the outside of the adjustable control motor 110. Two symmetrically arranged toggle force plates 114 are fixedly installed on the output shaft of the adjustable control motor 110; the blade support body 113 has two toggle grooves 115 along its own radial direction, and the two toggle force plates 114 are respectively arranged in the two toggle grooves 115, and a force-sensitive resistor 116 is overlapped between the two surfaces of each toggle force plate 114 in contact with the toggle groove 115.

A worm gear mechanism is provided between the output shaft of the adjustable control motor 110 and the transmission path of the blade support body 113, that is, the output shaft of the adjustable control motor 110 is fixed to the worm, and the rotating shaft of the worm wheel is fixed to the two shifting force plates 114, which is used to drive the blade support body 113 to rotate (the worm gear mechanism and the adjustable control motor 110 body are regarded as a whole, and the rotating shaft of the worm wheel is the output shaft of the adjustable control motor 110).

[0029] The inner wall sliding seal of the inner cylinder 103 is installed with a sliding piston body 117, and the sliding piston body 117 is fixedly installed on the bottom end of the sliding piston rod 118. The sliding piston rod 118 and the sliding piston body 117 are coaxially arranged, wherein the sliding piston rod 118 and the top end of the inner cylinder 103 are slidingly sealed, wherein the top end of the sliding piston rod 118 is fixedly installed with an adjusting servo motor support shell 119, and a spring 122 is fixedly installed between the adjusting servo motor support shell 119 and the top end of the outer surface of the outer cylinder 101, the spring 122 is arranged around the outside of the sliding piston rod 118, and the outside of the spring 122 is provided with a dustproof bellows 123, and the two ends of the dustproof bellows 123 are fixed to the adjusting servo motor support shell 119 and the outer cylinder 101. An adjustment servo motor 120 is fixedly mounted within the adjustment servo motor support housing 119. A rotating shaft 121 is fixedly mounted on the output shaft of the adjustment servo motor 120. The rotating shaft 121 is rotatably inserted into the inner axis of the sliding piston rod 118, and the bottom end of the rotating shaft 121 extends into the interior of the sliding piston body 117. A first rotating disk 124 and a second rotating disk 125 are rotatably mounted axially within the sliding piston body 117. The sliding piston body 117 is provided with a plurality of intermediate liquid flow holes 126. All intermediate liquid flow holes 126 are arranged in a circular array with equal spacing on the sliding piston body 117, and the axes of all intermediate liquid flow holes 126 are arranged parallel to the axis of the sliding piston body 117. The second turntable 125 is provided with through holes of the same number and diameter as the intermediate liquid circulation holes 126; the first turntable 124 is provided with through holes of two diameters, and the number of through holes of each diameter is the same as the intermediate liquid circulation holes 126; the second turntable 125 and the first turntable 124 are both provided with arc-shaped resistor bars, and the sliding piston body 117 is provided with two sliding conductive contacts 127 that are respectively slidingly and conductively matched with the two arc-shaped resistor bars, which are used to monitor the rotational position angle of the first turntable 124 and the second turntable 125 inside the sliding piston body 117. The second rotating disk 125 and the first rotating disk 124 are both rotatably coupled to frictional electromagnet supports 128 at their respective axial centers. Both frictional electromagnet supports 128 are fixedly coupled to the rotating shaft 121. Each frictional electromagnet support 128 is slidably mounted with multiple frictional electromagnets 129 in an embedded manner along its radial direction. All frictional electromagnets 129 corresponding to the first rotating disk 124 are magnetically frictionally coupled to the first rotating disk 124, while all frictional electromagnets 129 corresponding to the second rotating disk 125 are magnetically frictionally coupled to the second rotating disk 125. The sliding piston body 117, the first rotating disk 124, and the second rotating disk 125 are insulated from each other, and the sliding piston body 117, the first rotating disk 124, and the second rotating disk 125 are in a rotating, sealed relationship.

[0030] The operating principle of the high-dynamic-response electromagnetic damping system disclosed herein is as follows: When the seal-driving electromagnet 107 is activated, it generates a magnetic force that attracts the sealing magnetic ring 106, causing it to contact the seal-driving electromagnet 107. This separates the space between the outer cylinder 101 and the bottom sealing cover 105. This prevents the hydraulic oil inside the inner cylinder 103 from flowing through the bottom liquid flow hole 112, the adjustable flow damping tube 109, and the top liquid flow hole 104. In other words, no hydraulic oil flows in the flow path between the outer cylinder 101 and the inner cylinder 103 (between the inner wall of the outer cylinder 101 and the outer wall of the inner cylinder 103). At this time, the servo motor 120 is controlled and adjusted, and the output shaft of the servo motor 120 drives the rotating shaft 121 to rotate. The rotating shaft 121 can drive the two friction electromagnet support bodies 128 inside the sliding piston body 117 to rotate. When the rotating shaft 121 is rotated (before the servo motor 120 is started), the friction electromagnet 129 corresponding to the first turntable 124 or the second turntable 125 is energized, so that the friction electromagnet 129 generates magnetic force, and the friction electromagnet 129 and the first turntable 124 or the second turntable 125 attract and friction each other, so that the two friction electromagnet support bodies 128 form a fixed relationship (friction fixation) with the corresponding first turntable 124 or the second turntable 125 through the friction electromagnet 129. At this time, it is necessary to start the friction electromagnet 129 corresponding to the first rotary disk 124, so that the rotating shaft 121 drives the first rotary disk 124 to rotate through the friction electromagnet support body 128. Since two through holes of different diameters are provided on the first rotary disk 124, when the through hole with the larger diameter is coaxially aligned with the intermediate liquid flow hole 126, the hydraulic oil can pass through the intermediate liquid flow hole 126, that is, when the sliding piston rod 118 is pressurized, the sliding piston body 117 slides on the inner wall of the inner cylinder 103, causing the hydraulic oil to pass through the intermediate liquid flow hole 126. Regarding the liquid flow hole 126, when a smaller through-hole on the first rotating disk 124 is coaxially aligned with the intermediate liquid flow hole 126, the hydraulic oil flow path through the intermediate liquid flow hole 126 is reduced, thereby increasing the resistance to the sliding piston body 117 sliding against the inner wall of the inner cylinder 103. Therefore, by aligning through-holes of different diameters on the first rotating disk 124 with the intermediate liquid flow hole 126, the resistance to the sliding of the sliding piston body 117 against the inner wall of the inner cylinder 103 can be adjusted, thereby adjusting the damping force of the overall shock absorber. It should be noted that the through-hole on the second rotating disk 125 is always aligned with the intermediate liquid flow hole 126 to ensure the normal flow of hydraulic oil. The two sliding conductive contacts 127 are used to monitor the position of the through-holes on the second rotating disk 125 and the first rotating disk 124 (for example, one end of the arc-shaped resistor strip is connected in series with the sliding conductive contact 127 in a DC circuit, and the current in the circuit is used to determine the position of the through-holes on the second rotating disk 125 and the first rotating disk 124). At this time, it is used to fix several levels of adjustable damping force (the number of levels depends on the diameters of the through holes on the first rotary disk 124).

[0031] When continuously variable damping is required, the servo motor 120 needs to be controlled and adjusted. The output shaft of the servo motor 120 drives the rotating shaft 121, which in turn drives the through-holes on the second rotating disk 125 to be offset from the intermediate fluid flow hole 126 (similar to the distance from the first rotating disk 124 described above). This prevents the hydraulic oil on both sides of the sliding piston body 117 from flowing through the intermediate fluid flow hole 126. At this time, when the sliding piston rod 118 is subjected to force (external pressure and the elastic force of the spring 122), the sliding piston body 117 will push the hydraulic oil inside the inner cylinder 103 to flow, so that the hydraulic oil flows through the space between the outer cylinder 101 and the inner cylinder 103. Therefore, it is necessary to cut off the power to the sealing drive electromagnet 107 at this time, so that the sealing magnetic ring 106 is separated from the sealing drive electromagnet 107 under the tension of the tension spring 108. At this time, the hydraulic oil inside the inner cylinder 103, the outer cylinder 101, and the adjustable flow damping tube 109 can flow. When the sliding piston body 117 moves downward in the inner cylinder 103, the hydraulic oil will be squeezed into the outer cylinder 101 through the bottom liquid flow hole 112 and the adjustable flow damping tube 109. In this process, the hydraulic oil will flow inside the adjustable flow damping tube 109 (the same is true in reverse, but the difference is that the flow direction of the hydraulic oil is different), and hydraulic oil also flows inside the top liquid flow hole 104. The flow of hydraulic oil will exert force on the damping blade 111, and the damping blade 111 will transfer the force to the blade support body 113. The inner wall of the toggle groove 115 opened on the blade support body 113 will squeeze the force-sensitive resistor 116. After the force-sensitive resistor 116 is squeezed, the force direction of the damping blade 111, that is, the flow direction of the hydraulic oil, is known. The rotation direction and speed of the output shaft of the adjustable control motor 110 are controlled according to the flow direction of the hydraulic oil (millisecond-level control is performed by a computer). The damping blade 111 is stationary and the damping blade 111 will affect the flow of hydraulic oil inside the flow damping adjustable tube 109. The resistance force is the greatest. When the damping blade 111 rotates along the flow direction of the hydraulic oil (the force direction of the damping blade 111 is the same as the flow direction of the hydraulic oil), the resistance to the hydraulic oil will be reduced. The faster the rotation speed of the damping blade 111, the smaller the resistance force (controlled by the adjustable control of the output shaft speed of the motor 110), thereby controlling the resistance of the sliding piston body 117 sliding inside the inner cylinder 103. Therefore, the damping force of the sliding piston body 117 sliding inside the inner cylinder 103 can be controlled by adjusting the speed of the output shaft of the motor 110, thereby realizing the function of stepless and continuously adjustable damping.
