Technical Field

[0002] An inertia container is a mechanical element whose two ends can move relative to each other and whose output is proportional to the relative acceleration between the two ends. It has the advantages of small mass, small volume and flexible installation under the same mass effect at two ends. The ratio of the output to the relative acceleration at both ends is called "inertia coefficient" or "inertia". By reasonably designing the inertia container, an inertia far greater than its own physical mass can be generated.

[0003] At present, there are various forms of inertia capacitors. However, due to their respective working principles and structures, the performance of different inertia capacitors is also limited. Hydraulic inertia capacitors have problems with connection stiffness and liquid leakage. The circuit stability of electromagnetic inertia capacitors will affect the working stability of the inertia capacitor. The advantage of mechanical inertia capacitors is that they do not require oil supply or circuit systems, and their working performance is stable. The principle of mechanical inertia capacitors is to change the form of motion through a transmission mechanism, such as converting translation into rotation to produce an inertia effect. Common forms include gear rack type, ball screw type, etc. However, most of the current mechanical inertia capacitors are fixed inertia capacitors and cannot meet the requirements of changing the inertia coefficient as needed. Some existing variable inertia capacitors are difficult to change inertia and difficult to adjust inertia steplessly.

[0033] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms and other features not clearly described in this technical solution are all considered to be common technical features disclosed in the prior art.

[0034] Example 1

[0035] This embodiment provides a slant-plate type nonlinear inertia container with adjustable inertia, such as Figure 1-8 As shown, it includes: a slide rail assembly 1, a mounting base 2, a support plate 3, a swash plate assembly 4, a connecting rod 5, an axle seat 6, and a connecting ring 7; one end of the connecting rod 5 is connected to the swash plate assembly 4, and the other end of the connecting rod 5 is inserted into the axle seat 6;

[0036] The slide rail assembly 1 includes: a linear guide rail 101, a slider 102, and the slider 102 is installed in the linear guide rail 101; the mounting base 2 includes: a bracket 201, an adjustment push rod 202, and a hinge support 203, and the bracket 201 is installed on the slider 102; the support plate 3 includes: a flange 301, a hinge 302, and a fixed shaft 303, and the support plate 3 is installed on the hinge support 203 through the hinge 302;

[0037] The mounting base 2 is slidably disposed on the slide rail assembly 1, and the support plate 3 is hinged on the mounting base 2;

[0038] The swash plate assembly 4 comprises: a swash plate 401, a flywheel 402, a ball joint bearing 403, a fixing nut 404, an inner gear ring 405, a sun gear 406, and a planetary gear 407. The swash plate assembly 4 is integrally mounted on the fixed shaft 303. The inner gear ring 405 is fixedly connected to the support plate 3 through the flange 301. The planetary gear 407 is mounted on the swash plate 401. The sun gear 406 is fixedly connected to the flywheel 402. The swash plate assembly 4 is mounted on the fixed shaft 303. The swash plate 401 forms an oblique angle with the horizontal plane, and the oblique angle is adjustable.

[0039] One end of the connecting rod 5 is connected to the ball joint bearing 403; the connecting rod 5 includes a crankshaft 501 and an input shaft 502 that are connected to each other; a sliding bearing 601 is installed in the shaft seat 6; the connecting ring 7 includes: a front bearing seat 701, a bidirectional thrust ball bearing 702, a locking nut 703, and a rear bearing seat 704; the bidirectional thrust ball bearing 702 is installed between the front bearing seat 701 and the rear bearing seat 704, and is used to bear axial loads and play a supporting and rotating role; the locking nut 703 is used to fix the connecting rod 5.

[0040] In a specific implementation, the adjusting push rod 202 is connected to the bracket 201 via threads, and the adjusting push rod 202 performs linear motion relative to the bracket 201. A spherical top is provided at the end of the adjusting push rod 202, and the support plate 3 is supported by the top.

[0041] In a specific implementation, the swash plate assembly 4 is connected to the fixed shaft 303 via a rolling bearing, and the support plate 3 does not rotate but only rotates around the hinge support 203 to change the bevel angle of the swash plate 401 .

[0042] In a specific embodiment, the crankshaft 501 is connected to the swash plate assembly 4 via a ball joint bearing 403, and the crankshaft 501 is also connected to the output shaft 502 via a hinge. The crankshaft 501 rotates in a vertical plane around the axis of the output shaft 502 and simultaneously rotates slightly around the hinge.

[0043] In a specific embodiment, the rotation center of the crankshaft 501 in the plane facing the swash plate 401, that is, the input shaft 502 and the geometric center of the swash plate do not coincide with each other, but are offset in the horizontal direction for a distance to avoid the dead point of the device.

[0044] In a specific embodiment, the crank arm length of the crankshaft 501 is equal to the rotation radius of the ball joint bearing 403 in the plane facing the swash plate 401, and the overall axial length of the crankshaft 501 is greater than or equal to 3.5 times the rotation radius of the ball joint bearing 403 in the plane facing the swash plate 501, so as to ensure that the influence of the crankshaft rotation angle on the output can be ignored.

[0045] In a specific embodiment, a planetary gear system is installed in the swash plate device 4, wherein the inner gear ring 405 is fixedly connected to the support plate 3 through the flange 301, the planetary gear 407 is installed on the swash plate 401, and the sun gear 406 is fixedly connected to the flywheel 402. The inertia effect is enhanced by changing the transmission ratio.

[0046] In a specific implementation, the input shaft 502 is installed in the sliding bearing 601, and the input shaft 502 performs both linear reciprocating motion and rotational motion relative to the shaft seat 6, and the connecting ring 7 installed at the end of the input shaft 502 performs linear reciprocating motion.

[0047] In a specific implementation, the connecting ring 7 is connected to the end of the input shaft 502 through a front bearing seat 701 , a bidirectional thrust ball bearing 702 , a locking nut 703 and a rear bearing seat 704 .

[0048] In a specific embodiment, the slider 102 is installed in the linear guide rail 101, moves up and down along the linear guide rail 101, and is fixed by a locking screw 103. It is ensured that the position of the input shaft is fixed and the rotation center height of the swash plate is always aligned with the input shaft axis height.

[0049] The present invention proposes a swash plate type nonlinear inertia container with adjustable inertia. When the inertia size needs to be adjusted, the locking screw 103 is first unlocked to allow the slider 102 to move up and down along the linear guide rail 101, and then the adjustment push rod 202 is adjusted to change the bevel angle of the swash plate device 4. At the same time, since the axis of the input shaft 502 and the rotation center height of the swash plate 401 remain relatively stationary, the height of the bracket 2 will change with the slider 102.

[0050] The smaller the angle of the swash plate device 4 is, the smaller the inertia generated is, and the larger the angle of the swash plate device 4 is, the larger the inertia generated is. After the inertia is adjusted, the locking screw 103 is locked to keep the slider 102 fixed. At this time, the input end should be in a balanced state, and the inertia container can start working.

[0051] When the input shaft 502 reciprocates, the crankshaft 501 is connected to the swash plate 401, and the crankshaft 501 generates a force component perpendicular to the swash plate plane and a force component parallel to the swash plate plane on the swash plate 401, wherein the force component parallel to the swash plate plane generates a rotational torque on the swash plate 401, causing it to rotate, thereby realizing the inertia effect. Due to the quick return characteristics of the connecting rod, the inertia of the device has obvious nonlinear characteristics.

[0052] By connecting the swash plate 401 with the planetary gear 407 while keeping the inner ring gear 405 fixed, the sun gear 406 can reach the maximum transmission ratio. The flywheel 402 is fixedly connected to the sun gear 406 to amplify its inertia, thereby obtaining a greater inertia-capacity effect.

[0053] The derivation process of the inertia capacity characteristic principle of the inertia container is as follows:

[0054] like Fig. 9 , Fig.10 As shown, it is assumed that the rotation radius of the ball joint bearing in the plane of the swash plate is r, the offset distance of the crankshaft rotation center (input shaft) is e, the displacement input by the input shaft end is x, the angle between the swash plate and the horizontal plane is an acute angle α, the angle rotated by the crankshaft around its rotation center is θ, the angle rotated by the swash plate from the equilibrium position is θ0, and the end force of the inertia container is F in , the equivalent moment of inertia of the device is I. Assume that the moments of inertia of the swash plate (planet carrier), planetary gear, sun gear, and flywheel are I C ,I P ,I S ,I f The number of teeth of the inner ring gear, planetary gear and sun gear are Z R , Z P 、z S , then the transmission ratio of the planetary gear train is:

[0055]

[0056] According to the law of conservation of energy, the equivalent moment of inertia is equal to the sum of the moment of inertia of each component multiplied by the square of the ratio of the angular velocity of each component to the angular velocity of the equivalent component. Taking the swash plate (planet carrier) as the equivalent component, the equivalent moment of inertia I of the device is:

[0057]

[0058] It can be seen from formula (2) that the planetary gear system effectively amplifies the rotational inertia of the device, so that the device can have a larger inertia coefficient.

[0059] The relationship between input displacement x and rotation angle θ is as follows:

[0060] x=rcosα·sinθ (3)

[0061] By taking the derivative of formula (3), we can get:

[0062]

[0063] in represents the input acceleration, then the angular acceleration of the swash plate It can be expressed as:

[0064]

[0065] If we temporarily ignore the eccentricity and assume that e=0, then θ0=θ. According to the torque relationship of the swash plate, we can get:

[0066]

[0067] Substituting equation (5) into equation (6), we can solve for F in :

[0068]

[0069] Let the limit stroke rcosα be X, then we have the following relationship:

[0070]

[0071] Substituting equation (8) into equation (7), we get F in It can be expressed as:

[0072]

[0073] When e≠0, when the crank angle θ rotates to 90°, the angle of the swash plate The theoretical limit travel of the device is:

[0074]

[0075] Substitute the angle θ0 and recalculate, then equation (9) becomes:

[0076]

[0077] Formula (11) can be simplified as:

[0078]

[0079] Among them, B is the inertia coefficient, C is the damping coefficient, B and C are functions with input displacement x as independent variables, and the expression of inertia coefficient B is:

[0080]

[0081] The expression of damping coefficient C is:

[0082]

[0083] Formula (12) shows that the output of the inertia container is related to the square of the input acceleration and the input speed, which is a combination of inertia force and nonlinear damping force, and the main output is inertia force; Formula (13) shows that the inertia container has a small inertia when the input displacement is small, and a large inertia when the input displacement is large, and has an adaptive nonlinear inertia characteristic; Formula (14) shows that the damping force is opposite to the inertia force, and the damping force increases first and then decreases with the increase of displacement. This characteristic can reduce the output under small displacement conditions without affecting the inertia characteristics under large displacement conditions. When the swash plate angle is adjusted, α changes. When α increases, the limit stroke X decreases, and the inertia coefficient A increases. On the contrary, when α decreases, the inertia coefficient A decreases, that is, the adjustability of the inertia coefficient.

It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work.
