Description

Technical Field

[0001] This invention relates to the field of automotive parts, and in particular to an anti-torsion rod suspension. Background Technology

[0002] The engine and body of a car are usually connected by an anti-torsion bar. The anti-torsion bar is used to counteract the excitation force generated by the engine during the operation of the car, thereby reducing vibration and improving quietness.

[0003] Traditional anti-torsion rod suspensions typically include a rod bracket body, a large bushing, and a small bushing. The rod bracket body has a large bushing mounting hole and a small bushing mounting hole at both ends. The large bushing is installed in the large bushing mounting hole, and the small bushing is installed in the small bushing mounting hole. The large and small bushings are used to connect to the car's engine and body, respectively.

[0004] As people pay increasing attention to environmental protection, car engine technology is constantly being innovated to improve fuel efficiency and reduce energy consumption. One common practice to meet emission regulations is to downsize the engine from a naturally aspirated V6 to a turbocharged L4. However, this can lead to some problems: for example, the reduction in the number of cylinders and the increase in torque result in increased excitation force; additionally, the increased compression ratio also leads to increased high-frequency excitation force.

[0005] The traditional anti-torsion bar mounts described above are insufficient for effectively isolating vibrations under all operating conditions, especially during the frequent start-stop cycles of a four-cylinder engine, which often generates significant vibrations. While these traditional anti-torsion bar mounts offer some damping capability, when the engine operates at a high excitation frequency, the natural frequency of the anti-torsion bar mount tends to approach the engine's excitation frequency, leading to resonance and a surge in stress, thus affecting the vehicle's quietness and comfort. Currently, changing the material of the tie rod can address these issues, but the effect is limited and dynamic response cannot be achieved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an anti-torsion tie rod suspension with a simple structure that can actively adapt to different working conditions.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: An anti-torsion tie rod mount includes a tie rod bracket, a large bushing for connection to the engine, and a small bushing for connection to the vehicle body. The left and right ends of the tie rod bracket are respectively the large bushing mounting end and the small bushing mounting end. The large bushing is mounted at the large bushing mounting end, and the small bushing is mounted at the small bushing mounting end. An active vibration damping device is provided inside the tie rod bracket to generate an active control force opposite to the direction of engine vibration. The active vibration damping device is disposed between the large bushing mounting end and the small bushing mounting end.

[0008] The tie rod bracket has a cavity for mounting the active vibration damping device. The cavity is located between the large bushing mounting end and the small bushing mounting end, and the active vibration damping device is installed in the cavity.

[0009] The active vibration absorption device is an electromagnetic actuator, which includes a mover that can be moved back and forth in the tie rod bracket and a stator that is fixedly installed in the tie rod bracket. The stator includes a magnetic yoke, with permanent magnets disposed at its upper and lower ends. The magnetic poles of the permanent magnets are arranged in a left-right configuration, consistent with the direction from the large bushing mounting end to the small bushing mounting end. Specifically, the N pole of the upper permanent magnet and the S pole of the lower permanent magnet are vertically aligned, and the S pole of the upper permanent magnet and the N pole of the lower permanent magnet are vertically aligned. A coil frame is fitted around the outside of the magnetic yoke, and a coil is wound on the coil frame. The moving part includes a mass block with a through cavity running horizontally. The stator is disposed in the through cavity. In the unpowered state, an initial magnetic field condition is formed by the two permanent magnets, so that the mass block is positioned without force in the vertical direction. When a control current is applied to the coil, the magnetic field generated by the yoke and the permanent magnet interacts, driving the mass block to reciprocate in the left-right direction, thereby generating the active control force.

[0010] The mass block is provided with elastic reset mechanisms at both its left and right ends.

[0011] The elastic reset mechanism is a spring sheet group composed of multiple spring sheets stacked side by side. Each spring sheet has two through-slots spaced back and forth, and the two through-slots are mirror-symmetrically arranged. The spring sheet is separated by the two through-slots to form an installation part and a free part. The part located between the two through-slots is the free part. The multiple installation parts formed by the multiple stacked spring sheets constitute the installation part of the spring sheet group, and the multiple free parts formed by the multiple stacked spring sheets constitute the free part of the spring sheet group. The installation part is fixedly connected to the mass block, and the free part has a connection area for fixedly connecting to the stator. The connection area is fixedly connected to the stator. When the mass block reciprocates left and right, the mounting part moves synchronously with the mass block, and the portion of the free part excluding the connecting area deforms. After power is cut off, the mass block is reset by the spring plate group.

[0012] The dividing groove includes a vertically arranged first dividing section and a second dividing section, which are spaced apart vertically. The upper and lower ends of the first dividing section are connected by an inwardly tapering first upper dividing section and a first lower dividing section. The upper and lower ends of the second dividing section are connected by an inwardly tapering second upper dividing section and a second lower dividing section. The first lower dividing section and the second upper dividing section are connected by a third dividing section, and the two third dividing sections form the connecting area.

[0013] The corresponding area of ​​the mounting part forms a vibration isolation area through the cooperation of the first lower partition, the third partition and the second upper partition, and a buffer vibration isolation sheet is provided between the coil frame and the vibration isolation area.

[0014] Each of the aforementioned spring plate assemblies has a cover plate fixedly connected to its outer side.

[0015] The upper and lower parts of the coil frame are respectively provided with winding sections, and the coils are wound on the two winding sections respectively, with the winding directions of the two coils being the same. The connecting area is located between the two winding sections, and the free section is provided with a left-right through clearance chamber corresponding to the position of the winding section.

[0016] The mass block is formed by stacking and pressing multiple silicon steel sheets in left and right layers.

[0017] The coil frame is made up of two half-shells joined together.

[0018] A connector is threaded through the stator and is fixedly installed inside the tie rod bracket.

[0019] The connector is a fixing bolt, and the corresponding insertion position is the location where the connection area is set. The corresponding installation positions of the connection area, coil frame, and magnetic yoke are respectively available for the shank of the fixing bolt to pass through. The shank of the fixing bolt passes through the connection area of ​​the spring plate group on the left side, the left half shell of the coil frame on the left side, the magnetic yoke, the right half shell of the coil frame on the right side, and the connection area of ​​the spring plate group on the right side in sequence from left to right. The end of the shank of the fixing bolt extends outward and is locked by a matching nut. Then the connection areas on the two spring plate groups are fixed by the head of the fixing bolt and the nut respectively.

[0020] The fixing bolt has a through threaded hole, the small bushing connection end has a small bushing mounting cavity for installing the small bushing, the tie rod bracket is provided with a connecting through hole that connects the small bushing mounting cavity and the cavity, and a locking bolt that mates with the threaded hole is provided in the connecting through hole. The rod of the locking bolt is screwed into the threaded hole to achieve the fixed installation of the entire active vibration absorption device in the cavity.

[0021] Compared with the prior art, the advantages of the present invention are as follows: (1) By setting an active vibration absorption device inside the tie rod bracket, the active vibration absorption device is used to generate a control force opposite to the vibration direction of the engine, thereby actively canceling the vibration and effectively solving the problem that traditional structures are prone to resonance under engine start-stop and high-frequency excitation. (2) This active vibration absorption device can dynamically adjust the force according to the real-time operating conditions of the engine, thereby meeting the high-efficiency vibration isolation under all operating conditions, and significantly improving the quietness and comfort of the vehicle. (3) The active vibration damping device is built into the tie rod bracket and located between the mounting ends of the two bushings. The structure is simple and compact, and there is no need to change the original installation form. The space of the tie rod bracket is fully and reasonably utilized, and the cost is low.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] As shown in the figure, an anti-torsion tie rod suspension includes a tie rod bracket 1, a large bushing 2 for connecting to the engine, and a small bushing 3 for connecting to the vehicle body. The left and right ends of the tie rod bracket 1 are respectively the large bushing mounting end 11 and the small bushing mounting end 12. The large bushing 2 is installed at the large bushing mounting end 11, and the small bushing 3 is installed at the small bushing mounting end 12. An active vibration damping device 4 is provided inside the tie rod bracket 1 to generate an active control force opposite to the direction of engine vibration. The active vibration damping device 4 is located between the large bushing mounting end 11 and the small bushing mounting end 12.

[0025] In this specific embodiment, the tie rod bracket 1 has a cavity 10 for mounting the active vibration damping device 4. The cavity 10 is located between the large bushing mounting end 11 and the small bushing mounting end 12, and the active vibration damping device 4 is installed inside the cavity 10. By making reasonable use of the space within the tie rod bracket 1 itself, the overall structure is compact, requiring no changes to the overall shape of the suspension, thus facilitating the layout and installation within the vehicle. Sufficient space is provided within the cavity 10 to allow the moving part of the active vibration damping device 4 to reciprocate left and right.

[0026] In this specific embodiment, the active vibration absorption device 4 is an electromagnetic actuator, which includes a mover that can be moved back and forth in the tie rod bracket 1 and a stator that is fixedly installed in the tie rod bracket 1. The stator includes a magnetic yoke 41, with permanent magnets 42 disposed at its upper and lower ends. The magnetic poles of the permanent magnets 42 are arranged in a left-right configuration, consistent with the direction from the large bushing mounting end 11 to the small bushing mounting end 12. Specifically, the N pole of the upper permanent magnet 42 and the S pole of the lower permanent magnet 42 are vertically aligned, and the S pole of the upper permanent magnet 42 and the N pole of the lower permanent magnet 42 are vertically aligned. A coil frame 43 is fitted around the outside of the magnetic yoke 41, and a coil (not shown in the figure) is wound on the coil frame 43. The mover includes a mass block 45, which has a through cavity 451 that runs from left to right. The stator is set inside the through cavity 451. In the unpowered state, an initial magnetic field condition is formed by two permanent magnets 42, so that the mass block 45 is positioned without any force in the vertical direction. When a control current is applied to the coil, the magnetic field generated by the yoke 41 and the permanent magnet 42 interacts, driving the mass block 45 to reciprocate in the left-right direction (from the large bushing mounting end 11 to the small bushing mounting end 12, which is the axial direction of the tie rod bracket 1), thereby generating an active control force.

[0027] Electromagnetic actuators have the characteristics of fast response speed, precise control, wide frequency range, and stable output power. When used as the active vibration absorption device 4 in this invention, they can effectively generate an active control force that is opposite to the engine vibration, realize real-time and active vibration cancellation, and thus fundamentally solve the resonance problem.

[0028] The arrangement of the permanent magnets 42 forms a symmetrical magnetic field when no power is applied, so that the mover is in a state of magnetic equilibrium in the vertical direction. Precise initial positioning can be achieved without additional positioning devices, and the structure is simple and reliable.

[0029] The magnetic yoke 41 is composed of multiple silicon steel sheets stacked side-by-side. Each silicon steel sheet has corresponding positioning bosses and recesses, ensuring accurate, reliable, and efficient alignment and fixation between the assembled silicon steel sheets. The number of silicon steel sheets can be increased or decreased according to specific needs, making it more flexible in use. Each silicon steel sheet is approximately 0.5mm thick. The magnetic yoke 41, composed of multiple stacked silicon steel sheets, has a high resistance, which reduces the induced electromotive force when the coil is energized, thereby reducing eddy current losses. The silicon steel sheets are made of iron-silicon alloy, and the permanent magnet 42 is made of neodymium iron-boron alloy.

[0030] The main body of the mover is a mass block 45. The mass block 45 has a large mass and high inertia, which is beneficial for generating sufficient actuation force. Simultaneously, as the mover, the large inertia of the moving parts results in good linearity of response and more precise control. The mass block 45 is formed by stacking multiple silicon steel sheets side-by-side. Each silicon steel sheet has corresponding positioning bosses and recesses, ensuring accurate, reliable, and efficient alignment and fixation between the assembled silicon steel sheets. The number of silicon steel sheets can be increased or decreased according to specific needs, making it more flexible. Each silicon steel sheet is approximately 0.5mm thick. The mass block 45, formed by stacking multiple silicon steel sheets, has a large resistance, which reduces the induced electromotive force when the coil is energized, thereby reducing eddy current losses.

[0031] Using silicon steel sheets can effectively suppress eddy currents generated in the iron core by alternating magnetic fields, reduce iron loss and heat generation, and improve the energy conversion efficiency and response speed of actuators.

[0032] In this specific embodiment, elastic reset mechanisms are provided at both ends of the mass block 45. These elastic reset mechanisms enable rapid reset of the moving element.

[0033] In this specific embodiment, the elastic reset mechanism is a spring plate group 46 formed by stacking multiple spring plates 460. Two through-slots 461 are provided on the spring plates 460 at intervals. The two through-slots 461 are arranged in a mirror image symmetrically. The spring plates 460 are separated by the two through-slots 461 to form an installation part 4601 and a free part 4602. The part located between the two through-slots 461 is the free part 4602. The multiple installation parts 4601 after stacking multiple spring plates 460 constitute the installation part 46011 of the spring plate group 46. The multiple free parts 4602 after stacking multiple spring plates 460 constitute the free part 46021 of the spring plate group 46. The installation part 46011 is fixedly connected to the mass block 45. The free part 46021 has a connection area 4603 for fixedly connecting to the stator. The connection area 4603 is fixedly connected to the stator. When the mass block 45 reciprocates left and right, the mounting part 46011 moves synchronously with the mass block 45, and the portion of the free part 46021 excluding the connecting area 4603 deforms. After power is cut off, the mass block 45 is reset via the spring plate assembly 46. The above-mentioned elastic reset mechanism has a simple structure and can achieve precise and rapid reset. Moreover, the spring plate assembly 46, through the above structure, not only provides the elastic force to reset the mass block 45, but also plays a motion guiding role, ensuring that the mover moves strictly in a straight line in the left and right direction and avoiding uneven wear. The spring plate assembly 46, through its structural design, separates the installation and fixing functions from the elastic deformation function, ensuring that the main deformation area—the free part 46021—can generate stable and consistent elastic deformation, thereby providing precise reset force.

[0034] In this specific embodiment, the dividing groove 461 includes a vertically arranged first dividing segment 4611 and a second dividing segment 4612, which are spaced vertically apart. The upper and lower ends of the first dividing segment 4611 are connected by an inwardly tapering first upper dividing segment 4613 and a first lower dividing segment 4614. The upper and lower ends of the second dividing segment 4612 are connected by an inwardly tapering second upper dividing segment 4615 and a second lower dividing segment 4616. The first lower dividing segment 4614 and the second upper dividing segment 4615 are connected by a third dividing segment 4617, forming a connection area 4603 between the two third dividing segments 4617. The shape design of the dividing groove 461 smoothly transitions stress, avoids stress concentration, significantly improves the reliability and durability of the spring sheet 460, and also achieves clear functional zoning.

[0035] In this specific embodiment, the corresponding area of ​​the mounting part 46011 forms a vibration isolation area 46013 through the cooperation of the first lower partition section 4614, the third partition section 4617, and the second upper partition section 4615. A buffer vibration isolation sheet 9 is provided between the coil frame 43 and the vibration isolation area 46013. This design can effectively isolate the transmission of high-frequency vibrations generated by the electromagnetic actuator itself to the vehicle body, while preventing abnormal noises caused by collisions between parts, thus improving the overall NVH performance of the vehicle.

[0036] In this specific embodiment, a cover plate 8 is fixedly connected to the outer side of each spring plate assembly 46. The cover plate 8 is mainly used to fix the spring plate assembly 46 and the mass block 45 to form a complete moving part. Through the joint action of the spring plate assembly 46 and the cover plate 8, the maximum stroke of the moving part can be mechanically limited, preventing damage to the internal structure due to overtravel under extreme working conditions, thereby improving the robustness and safety of the system.

[0037] In this specific embodiment, the upper and lower parts of the coil frame 43 are respectively provided with winding portions 431, and coils are wound on the two winding portions 431 respectively, with the winding directions of the two coils being the same. The above-mentioned double-coil design can enhance the electromagnetic driving force. The two coils are wound in the same direction, which can achieve the same force and ensure that the electromagnetic actuator can work normally.

[0038] In this specific embodiment, the connecting area 4603 is located between the two winding portions 431, and a through-hole 46024 is provided on the free portion 46021 corresponding to the position of the winding portion 431. The design of the through-hole 46024 provides physical space for the coil, ensuring unobstructed magnetic circuitry. At the same time, the coil frame 43 can be inserted into the through-hole 46024, achieving efficient integration of electrical components and mechanical structure, and reducing the overall volume.

[0039] In this specific embodiment, the coil frame 43 is formed by splicing two half-shells (430, 432) together. This facilitates assembly and reduces production costs.

[0040] In this specific embodiment, a connector is threaded through the stator and is fixedly installed inside the tie rod bracket 1.

[0041] In this specific embodiment, the connector is a fixing bolt 7, and the corresponding insertion position is the position where the connection area 4603 is set. The corresponding installation positions of the connection area 4603, the coil frame 43, and the magnetic yoke 41 are respectively available for the rod of the fixing bolt 7 to pass through. The rod of the fixing bolt 7 passes through the connection area 4603 of the spring plate group 46 on the left side, the left half shell 430 of the coil frame 43 on the left side, the magnetic yoke 41, the right half shell 432 of the coil frame 43 on the right side, and the connection area 4603 of the spring plate group 46 on the right side in sequence from left to right. The end of the rod of the fixing bolt 7 extends outward and is locked by a matching nut 101. Then the connection areas 4603 on the two spring plate groups 46 are respectively pressed and fixed by the head of the fixing bolt 7 and the nut 101.

[0042] The above design uses a single fixing bolt 7 to simultaneously connect and fix the stator, coil frame 43 and spring sheet assemblies 46 on both sides, integrating multiple components into a robust modular assembly, simplifying the assembly process and enhancing overall integrity.

[0043] In this specific embodiment, the fixing bolt 7 has a through threaded hole 71, and the small bushing mounting end 12 has a small bushing mounting cavity 121 for mounting the small bushing 3. The tie rod bracket 1 is provided with a connecting through hole 18 connecting the small bushing mounting cavity 121 and the cavity 10. A locking bolt 17 that mates with the threaded hole 71 is provided in the connecting through hole 18. The shank of the locking bolt 17 is screwed into the threaded hole 71, thereby achieving the fixed installation of the entire active vibration absorption device 4 in the cavity 10. By utilizing the channel leading to the small bushing mounting cavity 121, the entire active vibration absorption module can be fastened to the tie rod bracket 1 from the outside, realizing modular installation and maintenance, and facilitating production and after-sales service.

[0044] In this specific embodiment, the mounting portions 46011 of the mass block 45, the two spring plate groups 46, and the corners of the two cover plates 8 are fixedly connected by bolts 100. The corresponding holes on the mounting portions 46011 of the mass block 45 and the two spring plate groups 46 are all through holes. The corresponding hole on one cover plate 8 is a through hole, and the corresponding hole on the other cover plate 8 is a screw hole.

[0045] When this anti-torsion tie rod suspension is applied to an automobile, the active vibration damping device 4 is controlled by a corresponding controller. This controller is electrically connected to the vehicle control system. The vehicle control system monitors the engine speed, load, and other operating parameters in real time through sensors, and estimates or measures the vibration frequency and phase generated by the engine. This information is sent to the controller of the active vibration damping device 4. The controller calculates and generates a control current signal with the same frequency and opposite phase as the engine vibration. This control current is fed into the coil wound on the coil frame 43, causing the yoke 41 to generate a magnetic field. At this time, the magnetic attraction force on the mass block 45 is provided by the superposition of the magnetic field generated by the yoke 41 and the magnetic field of the permanent magnet 42. Since the stator is fixed relative to the tie rod bracket 1, the mover moves left and right (axial direction of the tie rod bracket 1) and causes the spring plate group 46 to deform. The inertial force generated by the movement of the mover is the active control force opposite to the direction of engine vibration. This force acts on the force transmission path between the engine and the vehicle body to actively cancel and suppress the vibration transmitted from the engine. The controller can precisely adjust the amplitude and direction of the mover's movement by changing the magnitude and direction of the control current in real time, thereby achieving dynamic tracking and cancellation of vibrations at different operating conditions and frequencies, effectively avoiding the resonance problem that is prone to occur in traditional structures at specific frequencies. When the control current is removed (such as when the engine is turned off), the free part 46021 of the spring plate group 46, which has undergone elastic deformation during the movement of the mover, will release the stored potential energy, generate a restoring force, and drive the mass block 45 to accurately return to the central equilibrium position, preparing for the next operation.
