Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, the terms "first" and "second" are used not to denote any order or importance, but rather to distinguish one element from another. In addition, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements, unless otherwise indicated.
The suspension system is an assembly of a force transmission connecting device between a vehicle body and an axle, and is used for transmitting vertical counter force (supporting force), longitudinal counter force (driving force and braking force) and lateral counter force acting on wheels on a road surface and moment caused by the counter force to a vehicle frame so as to ensure normal running of the vehicle. Vertical reaction forces exerted on the wheels by the road surface during vehicle travel are often impulsive, and when such forces are transmitted to the vehicle body, they may cause early damage to the vehicle components and also cause discomfort to the driver. To mitigate impact, resilient elements must be incorporated into the vehicle suspension system to maintain a resilient connection between the vehicle body and the axle.
In the related art, as shown in fig. 6, the elastic element usually includes a mechanical spring 9, however, such a spring is usually linear in stiffness, it is difficult to meet the stiffness requirement of the vehicle under different loads, and during the actual use, the spring fails, which results in severe vehicle bump and, in severe cases, affects the driving safety of the vehicle.
In order to solve the above technical problem, as shown in fig. 1 and 2, the present disclosure provides a damping system for a suspension, including a first magnetic member 1 disposed on a vehicle body 3 and a second magnetic member 2 disposed on a vehicle axle 4, where the first magnetic member 1 corresponds to the second magnetic member 2 in vertical position, and the first magnetic member 1 and the second magnetic member 2 are disposed opposite to each other in terms of magnetic poles. Through the technical scheme, the elastic element of the suspension system is realized through the repulsive force of the magnetic piece, and the bearing force of the elastic element is not transmitted through the elastic element, so that the conditions that the traditional mechanical spring is easy to break and lose efficacy in the use process and the like can be avoided; in addition, the rigidity of the vibration damping system changes along with the distance between the magnetic parts, and the distance between the magnetic parts changes along with the load, so that the rigidity of the vibration damping system can be automatically adjusted along with the change of the load, the smoothness and the operation stability of the vehicle in the driving process are effectively improved, and the comfort of passengers is improved.
The vibration damping system provided by the present disclosure may be used in place of or in conjunction with vibration damping systems of the related art. For example, for a torsion beam type suspension, the springs of the related art may be replaced with the damping system provided by the present disclosure that utilizes magnetism, which may be used in conjunction with a damper; for multi-link suspension, the damping system using magnetism provided by the present disclosure can replace the assembly device of spring and damper in the related art.
In order to make the first magnetic member 1 and the second magnetic member 2 correspond to each other in the vertical position all the time during the driving process, a guiding device (not shown in the figure), such as a guiding sleeve, may be sleeved on the outer sides of the first magnetic member 1 and the second magnetic member 2. Certainly, the vehicle body and the axle can be connected through other parts, and the positions of the vehicle body and the axle are relatively fixed, so that even if a guide device is not additionally arranged, the first magnetic part 1 and the second magnetic part 2 only generate small displacement in the driving process of the vehicle at the vertical position, and the impact-resistant function of the vehicle as a vibration damping system is not influenced.
In the present disclosure, the magnetic force of the first magnetic member 1 and/or the second magnetic member 2 is adjustable, i.e., the magnetic force of one or both of the first magnetic member 1 and the second magnetic member 2 is adjustable. By adjusting the magnetic force, the magnetic field intensity between the magnetic pieces can be changed, so that the distance between the magnetic pieces is changed, and the rigidity of the vibration damping system is further changed. Therefore, the driver can adjust the rigidity of the vibration damping system by himself to adapt to different road conditions. For example, on a relatively flat road surface, the rigidity of the vibration damping system is appropriately increased, and on a relatively rugged road surface, the rigidity of the vibration damping system is appropriately decreased to increase the flexibility thereof, so as to buffer the impact force of the road surface.
According to an embodiment of the present disclosure, as shown in fig. 4, the first magnetic member 1 may include a first permanent magnet, the second magnetic member 2 may include a second permanent magnet, a selectively energized spiral coil 5 is sleeved outside the first permanent magnet and/or the second permanent magnet, and the damping system further includes a battery 6 for supplying power to the spiral coil 5. That is, in one case, the first magnetic member 1 includes a first permanent magnet and a spiral coil 5 provided outside the first permanent magnet, and the second magnetic member 2 includes a second permanent magnet and a spiral coil 5 provided outside the second permanent magnet; in another case, the first magnetic member 1 includes a first permanent magnet and a spiral coil 5 sleeved outside the first permanent magnet, and the second magnetic member 2 includes a second permanent magnet; in another case, the first magnetic member 1 includes a first permanent magnet, and the second magnetic member 2 includes a second permanent magnet and a spiral coil 5 disposed outside the second permanent magnet. Through the technical scheme, when the spiral coil 5 is not electrified, the first permanent magnet and the second permanent magnet can provide certain buffer force for a vehicle, and the buffer force can automatically adjust the rigidity of the vibration damping system within a certain load range. In order to realize that a driver can automatically adjust the rigidity of the vibration damping system according to actual road conditions and expand the adjustment range of the rigidity of the vibration damping system, the spiral coil 5 which is selectively electrified can be sleeved outside the first permanent magnet and/or the second permanent magnet. Because the spiral coil 5 after being electrified can generate a magnetic field, the magnetic force between the first magnetic part 1 and the second magnetic part 2 can be adjusted through the matching of the magnetic field generated by the spiral coil 5 and the magnetic field of the corresponding permanent magnet.
According to an embodiment of the present disclosure, the spiral coil 5 may include a first coil and a second coil, the first magnetic member 1 may include a first coil disposed outside the first permanent magnet, and the second magnetic member 2 may include a second coil disposed outside the second permanent magnet. In the present embodiment, the first permanent magnet and the first coil have the same magnetic pole direction, and the second permanent magnet and the second coil have the opposite magnetic pole direction. Thus, when the first coil is energized, the magnetism of the first magnetic member 1 is strengthened, and the magnetic field intensity between the first magnetic member 1 and the second magnetic member 2 is increased; when the second coil is energized, the magnetism of the second magnetic member 2 is weakened, and the magnetic field strength between the first magnetic member 1 and the second magnetic member 2 is reduced. In this way, by adjusting the energization of the first coil or the second coil, the magnetic field intensity between the first magnetic member 1 and the second magnetic member 2 can be controlled to increase or decrease. Similarly, in another embodiment, the magnetic pole directions of the first permanent magnet and the first coil may be opposite, and the magnetic pole directions of the second permanent magnet and the second coil are the same, which may also implement the above-mentioned functions, and are not described herein again. Of course, in other embodiments, the magnetic pole directions of the first permanent magnet and the first coil may be communicated, and the magnetic pole directions of the second permanent magnet and the second coil may also be the same.
According to other embodiments of the present disclosure, the first magnetic member 1 and the second magnetic member 2 may also be electromagnets, respectively, which are in communication with the battery 6 to supply power to the electromagnets. When the first magnetic part 1 and the second magnetic part 2 respectively adopt electromagnets, the magnetic parts are required to be ensured to be always in an electrified state in the running process of the vehicle, and the current passing through the electromagnets is changed to adjust the rigidity of the vibration damping system. Or one of the first magnetic member 1 or the second magnetic member 2 is a permanent magnet, and the other is an electromagnet, and similarly, the rigidity of the damping system is adjusted by changing the magnitude of the current passing through the electromagnet.
In one embodiment of the present disclosure, the battery 6 may be a rechargeable battery that can be powered up when the spiral coil 5 cuts the magnetic induction wire. Referring to fig. 4, the spiral coil 5 is connected to the positive and negative electrodes of the battery 6. When the spiral coil 5 is not in the power-on state, in the running process of the vehicle, because the vehicle inevitably generates vertical jumping, relative movement is generated between the magnetic part and the spiral coil 5, namely the spiral coil 5 cuts the magnetic induction lines, so that according to the principle of electromagnetic induction, the vibration damping system forms a power generation device at the moment, and electric energy generated by cutting the magnetic induction lines is stored in the rechargeable battery 6. When the stiffness of the damping system needs to be adjusted, the helical coil 5 is powered by a battery. The electromagnetic device constituted by the first magnetic member 1, the helical coil 5 and the battery 6 can supplement electric energy when the stiffness of the damping system does not need to be adjusted, thereby saving energy of the vehicle itself and prolonging the running time of, for example, a hybrid or new energy vehicle. In other embodiments of the present disclosure, the battery 6 may also be a storage battery of the entire vehicle, so that the function of the damping system of the present disclosure can be realized only by using the storage battery of the entire vehicle without additionally adding a rechargeable battery.
According to an embodiment of the present disclosure, as shown in fig. 5, the damping system further includes: vibration frequency detection means 7 for detecting the vibration frequency of the vehicle body; and a controller 8 for controlling the current passing through the helical coil 5 according to the vibration frequency to adjust the magnetic force of the first magnetic member 1 and/or the second magnetic member 2. Through the control device, the vibration damping system can be automatically controlled according to actual road conditions. Specifically, the vibration frequency detection device 7 detects an actual vibration value of the vehicle body, and then transmits the value to the controller 8. The controller 8 compares the actual vibration value with a standard value preset inside the controller 8, if the actual vibration value exceeds the standard value, the controller 8 sends an instruction to the vibration reduction system, the spiral coil 5 is electrified, and the magnetic field intensity between the first magnetic member 1 and the second magnetic member 2 is adjusted, so that the vibration is reduced to a proper level.
In the present disclosure, as shown in fig. 2 and 3, in the case where the first magnetic member 1 includes a first permanent magnet and the second magnetic member 2 includes a second permanent magnet, the vibration damping system may further include a first mount 31 for fixing to the vehicle body 3, the first permanent magnet being provided on the first mount 31; and a second bracket 41 for fixing to the vehicle axle 4, the second permanent magnet being disposed on the second bracket 41. Specifically, the first support 31 may be welded to the vehicle body 3, and the first permanent magnet may be tightly clamped to the first support 31 to facilitate maintenance and replacement, or integrally welded to the first support 31. The second bracket 41 is provided on the vehicle axle 4 in a vertical position corresponding to the first bracket 31 so that the first permanent magnet and the second permanent magnet correspond in vertical position. Likewise, the second magnetic member 2 can be clamped or welded to the second support 41.
According to a second aspect of the present disclosure, there is also provided a vehicle suspension comprising the damping system for a suspension described above in the present disclosure. The vehicle suspension has all the advantages of the damping system, and the description is omitted.
According to a third aspect of the present disclosure, there is also provided a vehicle comprising the vehicle suspension described above in the present disclosure. The vehicle has all the beneficial effects of the vehicle suspension, and the detailed description is omitted.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, various possible combinations will not be separately described in this disclosure.
