Description

TECHNICAL FIELD

[0001] The application relates to the field of engineering vibration isolation technology, and particularly relates to a gas electromechanical inerter energy feeding device for a wheel hub drive automobile. BACKGROUND

[0002] In 2002, Professor Malcolm C. Smith of the University of Cambridge first proposed the concept of inerter, which well solves the problem that mechanical systems and circuit systems cannot be fully comparable; starting from the inerter concept, the second type of electromechanical similarity theory converts the correspondence between the mass element and the grounded capacitor element into the correspondence between the inerter element and the general capacitor element, which promotes the in-depth research of the electromechanical similarity theory.

[0003] In the article of "Design and modelling of a fluid inerter", it is mentioned that the spiral liquid inerter has the defects that the liquid in the hydraulic cylinder has viscous friction with the hydraulic cylinder wall, the work done by the force F cannot be fully converted into the kinetic energy of the liquid in the spiral copper pipe, and a part is converted into the kinetic energy of the liquid in the hydraulic cylinder, which leads to a high degree of nonlinearity of the spiral liquid inerter, and the spiral liquid inerter is not suitable for the case where the linearity of the inerter is required to be high; the patent CN109083967A proposes a spiral gas inerter, which expands the application range of the inerter, reduces the nonlinearity of the inerter, and makes the inerter more suitable for the case where the linearity of the inerter is required to be high, but the inerter mass coefficient cannot be adjusted, and the use demand of enterprises cannot be met.

[0004] In view of the above problems, it is necessary to improve the existing inerter so that it can meet the use demand of adjusting the inerter mass coefficient. SUMMARY

[0005] The application aims to solve the problem that the inerter mass coefficient of the existing spiral gas inerter cannot be adjusted, and based on this, the inerter and the damping are designed as an integrated device, which effectively reduces the nonlinearity of the inerter, improves the inerter mass coefficient, innovatively proposes the coupling design of connecting the gas inerter and the linear motor, improves the inerter mass ratio, and further improves the mechanical network design theory containing the inerter, and specifically, the application relates to a gas electromechanical inerter energy feeding device for a wheel hub drive automobile.

[0007] Further supplement to the technical solution, the gas type inerter includes a cylinder wall, a piston slidingly installed in the cylinder wall, a piston rod fixedly connected with the piston, and a spiral copper pipe arranged on the outer surface of the cylinder wall. The piston divides the cylinder wall into an upper working chamber and a lower working chamber, which are independent chambers not communicating with each other. The spiral copper pipe has a spiral upper port near one end of the upper lifting ring and a spiral lower port away from the other end. The spiral upper port is in communication with the inside of the upper working chamber, and the spiral lower port is in communication with the inside of the lower working chamber. Liquid plugs are arranged at a distance from the spiral upper port and the spiral lower port in the spiral copper pipe. Hydraulic oil is arranged in the spiral copper pipe between the two liquid plugs. A horizontal partition plate is arranged below the piston and the spiral copper pipe in the cylinder wall to separate the lower working chamber from a buffer stroke chamber. The piston rod is arranged at the center of the upper working chamber, the lower working chamber and the tank body. The upper end of the piston rod is integrally welded with the upper lifting ring, and the lower end of the piston rod is connected with the buffer stroke chamber and the linear motor through the horizontal partition plate.

[0008] Further supplement to the technical solution, a plurality of damping holes are arranged on the piston.

[0009] Further supplement to the technical solution, the buffer stroke chamber includes a stroke chamber arranged below the partition plate, a first buffer block fixedly connected with the piston rod, a first connecting rod pin arranged on the first buffer block, a first connecting rod connected with the first connecting rod pin, a crank pin connected with the first connecting rod, a crank connected with the crank pin, a hinge shaft connected with the crank, a hinge shaft seat connected with the hinge shaft, a second connecting rod connected with the crank pin, a second connecting rod pin connected with the second connecting rod, a second buffer block connected with the second connecting rod pin, and a first support end face arranged between the stroke chamber and the linear motor.

The second buffer block is hingedly connected with the second connecting rod through the second connecting rod pin. The crank is hingedly connected with the first connecting rod and the second connecting rod through the crank pin. The second buffer block is fixedly connected with the piston rod.

[0010] Further supplement to the technical solution, the hinge shaft is arranged at the center of the hinge shaft seat. The two ends of the hinge shaft seat are fixed on the cylinder wall of the stroke chamber through bolts.

[0011] Further supplement to the technical solution, the hinge shaft seat is in V shape.

[0012] Further supplement to the technical solution, the first connecting rod and the second connecting rod are symmetrically arranged in front of and behind the crank.

[0013] Further supplement to the technical solution, when the crank is in the middle position symmetrical to the first connecting rod pin and the second connecting rod pin, the symmetry axis of the crank coincides with the symmetry center line of the first buffer block and the second buffer block, and the symmetry axis is perpendicular to the axis center line of the total mechanism; when the crank starts from the horizontal position and reaches the stroke end position, the angle between the symmetry axis of the first connecting rod and the second connecting rod and the axis center line of the total mechanism reaches the maximum.

[0014] Further supplement to the technical solution, the linear motor comprises a motor cylinder, a motor working cavity, a stator coil, a winding coil, a mover magnetic pole and a mover shaft, one end of the mover shaft is welded with the piston rod as a whole through the motor cylinder and a first support end face, and the mover shaft and the motor cylinder generate relative linear motion.

[0015] Further supplement to the technical solution, the motor cylinder is further provided with a second support end face below, and the mover shaft is welded with a lower lifting ring as a whole through the second support end face and the lower surface of the motor cylinder.

[0016] Further, the device can work in the following three working modes through the linear motor:

[0017] Energy feedback mode: in the case that the motor mover moves relative to the motor stator, that is, the mover magnetic pole moves relative to the winding coil in the stator coil, the magnetic flux direction of the mover changes during the movement, an alternating current potential is induced in the coil, the vibration energy of the system is recovered, and energy input is provided for other control systems through the external circuit;

[0018] Passive control mode: the external circuit is a passive network composed of resistance, inductance and capacitance without external energy, when the terminal voltage is applied to the passive network, the passive network impedance is equal to the mechanical impedance of the mechanical network, and energy dissipation and shock absorption of the system are realized;

[0019] Active control mode: the external circuit provides power and provides power for the linear motor, at this time, the gas electromechanical inerter is a force generator, cooperates with the designed buffer stroke chamber, and realizes active tuning control and vibration suppression of the vibration system.

[0020] The gas electromechanical inerter energy feedback device for the wheel hub drive automobile has the advantages that the gas electromechanical inerter energy feedback device for the wheel hub drive automobile is coupled by the gas electromechanical inerter and the linear motor, the flow inertia of the fluid in the spiral copper pipe is utilized to realize the effect of the inerter, compared with the liquid inerter, the linear degree is higher, the hydraulic oil in the spiral copper pipe only flows in the two liquid plugs, that is, the hydraulic oil flows in a certain range and does not flow into the cylinder, the viscous effect is weakened, and the power loss is greatly reduced.

[0021] The angle between the axis of the first connecting rod and the second connecting rod and the device axis is small in the buffer stroke chamber designed by the application, the radial force of the gas cylinder piston on the cylinder body during the stroke operation is small, the design requirements of relevant parts in structure and strength are reduced, the buffer device arrangement scheme rationally uses the horizontal space, and installation space can be effectively saved, so that the stability of the whole inertial container is higher by setting the connecting rod mechanism; and the crank double connecting rod pair in the scheme is basically a low pair with surface contact, has light wear and long service life, and can adapt to the working environment with large impact load; under the condition that the motion law of the mover shaft is unchanged, the mass inertia performance of the inertial device can be increased or reduced by adjusting the size of the crank and the connecting rod due to the non-uniform speed of the shaft and the connecting rod; compared with the original single shaft arrangement, the connecting rod mechanism has the characteristics of simplicity and light weight by cooperating with the damping element and the elastic element, and is more beneficial to the energy recovery of the whole inertial container.

[0022] And the application can include the following three working modes by using a linear motor: (1) energy feeding mode; (2) passive control mode; (3) active control mode; in the "energy feeding" mode, the vibration energy of the system is recovered to provide energy input for other control systems by an external circuit; in the "passive control" mode, a complex mechanical network can be integrated and designed, and under the action of an external source network, energy is dissipated and shock is reduced; in the "active control" mode, the gas type inertial container is used as a force generator, the system impedance is linearized by controlling the motor, and the structure is realized.

[0028] like Figure 1 As shown, a gas electromechanical inertial container power supply device for a hub-driven automobile includes a gas inertial container, a linear motor connected to the gas inertial container, and a buffer stroke chamber between the gas inertial container and the linear motor. An upper hanging ring 1 is welded to the top of the gas inertial container, and a lower hanging ring 28 is welded to the bottom of the linear motor. The gas inertial container includes a cylinder wall 22, a piston 24 slidably installed in the cylinder wall 22, a piston rod 27 fixedly connected to the piston 24, and a spiral copper tube 3 disposed on the outer surface of the cylinder wall 22. The piston 24 is provided with multiple damping holes 26. The piston 24 divides the cylinder wall 22 into an upper working chamber 25 and a lower working chamber 21, which are independent cavities that are not interconnected. The spiral copper tube 3 has an upper spiral port 2 near the upper hanging ring 1 and a lower spiral port 4 away from it. The upper spiral port 25 and the lower working chamber 26 are connected to the upper working chamber 25. 5. Internally connected, the lower spiral port 4 is connected to the lower working chamber 21 of the cylinder. Liquid plugs 23 are arranged in the spiral copper tube 3 at a distance from the upper spiral port 2 and the lower spiral port 4. Hydraulic oil is filled in the spiral copper tube 3 between the two liquid plugs 23. The liquid plugs 23 separate the oil and gas. The hydraulic oil flows back and forth in the spiral copper tube 3 between the liquid plugs 23 on both sides under the thrust of the piston 24. A horizontal partition 20 is provided in the cylinder wall 22 below the piston 24 and the spiral copper tube 3 to separate the lower working chamber 21 of the cylinder from the buffer stroke chamber 19 into two independent chambers that are not connected to each other. The piston rod is located in the upper working chamber 25 of the cylinder, the lower working chamber 21 of the cylinder, and the center of the tank. The upper end of the piston rod is welded to the upper lifting ring 1 and its lower end passes through the horizontal partition 20 and is connected to the buffer stroke chamber 19 and the linear motor.

[0029] Wherein, let the density of a section of liquid in the spiral copper pipe 3 be p, the length be l, the radius of the piston 24 be R, the radius of the cross section of the piston rod 27 be r, the cross-sectional area of the liquid in the spiral copper pipe 3 be A2, the relative displacement of the first end point and the second end point be x, and the velocity of the liquid in the spiral copper pipe 3 be u. Then the effective working area of the piston 24 is A1 = π(R 2 -r 2 ), the relative velocity of the first end point and the second end point is , the flow rate of the cross section of the liquid in the spiral copper pipe 3 is equal to the flow rate of the effective working cross section of the piston, so

[0030]

[0031]

[0032] If the gravity work of the liquid in the spiral copper pipe 3 and various losses are ignored, the work done by the force F is converted into the kinetic energy of the spiral motion of the liquid in the spiral copper pipe 3, and the power of the force F is equal to the change rate of the kinetic energy of the spiral motion of the liquid in the spiral copper pipe 3 with respect to time, that is,

[0033]

[0034] It can be obtained that:

[0035]

[0036] The above formula shows that the force F is proportional to the relative acceleration between the first end point and the second end point , which satisfies the characteristics of an inerter, so it can be seen that the spiral gas inerter is indeed an implementation form of an inerter. The ratio is called the inertia of the spiral gas inerter.

[0039] The working principle of the present application is as follows:

[0040] In Figure 1The working process of the gas electromechanical inertial damper energy feeding device for a wheel hub drive automobile is as follows: the upper hanging ring 1 is subjected to a downward force, the piston rod 27 drives the piston 24 to move downward, the piston 24 pushes the gas to move, the gas enters the spiral copper pipe 3 from the lower end port 4 of the spiral copper pipe, extrudes the liquid plug 23, and thus pushes the oil liquid between the liquid plug 23 in the pipe to move spirally, the oil liquid is subjected to a pushing force to reciprocate at the upper end port 2 and the lower end port of the spiral, and the mechanical effect of the inertial damper is formed.

[0041] Meanwhile, the piston rod 27 drives the first buffer block 5 and the second buffer block 29 to move linearly in the positive direction, the buffer blocks convert the linear motion received into the rotary motion of the first connecting rod 7-1 and the second connecting rod 7-2 through the connecting rod pin, the crank 8 is fixed to the hinge shaft 9 and is symmetrically distributed and moves synchronously, the speed of the swing of the directly connected connecting rod is slowed down, and the torque absorbed is transmitted to the symmetric connecting rod on the other side, the buffer block on the other side is driven to move linearly in the reverse direction, the reciprocating linear motion effect is achieved, and the inertial effect is generated.

[0042] Meanwhile, the piston rod 27 drives the mover shaft 15 integrally connected thereto to move up and down, the mover shaft 15 is one end point, the motor cylinder 10 is the other end point, and the relative linear motion is generated between the two end points, the relative motion occurs between the mover magnetic pole 12 arranged on the mover shaft 15 and the winding coil 11 of the motor stator coil 13 of the motor working cavity 14, the alternating electromotive force is induced, and the energy input is provided.
