Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a hydraulic mount according to an embodiment of the present invention; FIG. 3 is a drawing showing
Fig. 2 is an exploded view of the hydraulic mount.
As shown in fig. 2 and 3, the hydraulic mount in the embodiment of the present invention includes a mount upper housing 10, a mount arm 20, a mount main spring 30, a mount base 40, and a seal structure 60, where the mount upper housing 10 is connected to a vehicle body, the mount arm 20 is connected to a power assembly, and the mount base 40 is fixedly connected to the mount upper housing 10 through a main bolt 100. The suspension mount 40 forms a hydraulic chamber, the bottom of which is enclosed by a seal 60. When the power assembly generates vibration, oil in the hydraulic chamber flows. The hydraulic mount is further provided with a valve plate mechanism 50 shown in fig. 3, the valve plate mechanism 50 is mounted on the mount base 40 and located in the hydraulic chamber, and damping is generated by the flow of oil in the hydraulic chamber, so that the effects of damping vibration and reducing bumping are achieved.
The specific structure of the valve plate mechanism 50 can be understood by referring to fig. 4 and 5, and fig. 4 is an exploded view of the valve plate mechanism 50 in fig. 3; fig. 5 is a top view of the valve plate mechanism 50 in fig. 3.
The valve plate mechanism 50 in this embodiment includes a valve base 505, and the valve base 505 is used to separate the hydraulic chamber (not shown in the figure), and may be divided into a first chamber and a second chamber, and specifically, in fig. 2, the first chamber and the second chamber are distributed up and down to attenuate the conventional up-and-down vibration and bumping, and of course, it is not excluded that the hydraulic mount is applied to other positions to attenuate the vibration in other directions, such as the left-and-right vibration.
As shown in fig. 4 and 5, the hydraulic mount is provided with fastening bolts 507, the two ends of the valve base 505 are provided with matching bolt holes 505c, and the valve base 505 can be fixed in the suspension base 40 of the hydraulic mount by the fastening bolts 507 inserted into the bolt holes 505 c. Further, the valve base 505 is provided with at least one base through-hole 505b communicating both sides (upper and lower sides in fig. 4) of the valve base 505, a base center hole 505a is provided in the middle of the valve base 505 in fig. 4, and six base through-holes 505b are shown evenly distributed around the base center hole 505a, but of course, the number of the base through-holes 505c may be adjusted. The hydraulic chamber of the suspension mount 40 is divided into a first chamber and a second chamber, and the mount through hole 505b communicates the first chamber and the second chamber as a passage through which the divided first chamber and second chamber communicate.
The valve sheet mechanism 50 further includes at least one valve sheet installed on the valve base 505, the valve sheet covers at least a portion of each base through hole 505b in the conduction direction of the base through hole 505b, and the areas of the base through holes 505b covered by different valve sheets are different. The covering is performed in the conducting direction of the base through hole 505b, that is, the valve plate is not required to be completely attached to the base through hole 505b necessarily, and only the covering basically prevents the oil from directly flowing to the base through hole 505 b.
The valve plate is deformable by hydraulic pressure to open the covered base through hole 505b, so that when the hydraulic mount is vibrated, hydraulic pressure is generated by the flow of oil, and the hydraulic pressure can be applied to the valve plate to open (partially or fully open) the base through hole 505 b. That is, the valve plate in this embodiment must have the ability to deform, and may be made of metal or plastic.
In addition, the valve plate can cover at least a part of the base through hole 505b, and the hydraulic pressure required by the deformation of the valve plate with a large covering area is smaller than the hydraulic pressure required by the deformation of the valve plate with a small covering area. Thus, the area of the base through hole 505b to be opened is different according to the amplitude, thereby generating different damping, and specifically, the larger the amplitude, the larger the hydraulic pressure, and the larger the opened area.
With continued reference to FIG. 4 in particular, in this particular embodiment, valve train 50 includes two valve flaps, first valve flap 501 and second valve flap 502 shown in the figures, with first valve flap 501 and second valve flap 502 located on the same side of valve base 505. The covering area of the first valve plate 501 is the largest, and the covering area of the second valve plate 502 is smaller than that of the first valve plate 501, i.e. for the same base through hole 505b, the covering area of the first valve plate 501 is the largest and larger than that of the second valve plate 502. In this embodiment, in order to mount the valve plate, the first valve plate 501 is provided with a first center hole 501a, the second valve plate 502 is provided with a second center hole 502a, the first valve plate 501 and the second valve plate 502 are mounted by a fastener, the fastener includes a mounting bolt 506 and a mounting nut 503, the mounting bolt 506 is inserted into the first center hole 501a, the second center hole 502a, and the base center hole 505a, and the mounting nut 503 is screwed. Of course, the valve plate can be fixed to the valve base 505 by other means, and the fastening member can be, for example, a rivet, a pin, etc.
In fig. 4, first valve plate 501 and second valve plate 502 are both located on the upper side of valve base 505, second valve plate 502 is located between first valve plate 501 and valve base 505, support 504 is further disposed between second valve plate 502 and valve base 505, so that there is a certain distance between second valve plate 502, first valve plate 501 and valve base 505, the distance is the height of support 504, support 504 in fig. 4 is a plate structure, the height of support 504 is the thickness of the plate structure, support 504 is correspondingly provided with third center hole 504a, and first center hole 501a, second center hole 502a, third center hole 504a and base center hole 505a are coaxial, so that mounting bolt 506 can be inserted. The supporting member 504 may have a cylindrical structure according to the thickness variation, and the supporting member 504 may be integrated with the second valve plate 502, that is, the middle of the second valve plate 502 protrudes to provide a deformation space for itself. It can be understood that the area of the supporting member 504 should be the smallest, and the base through hole 505b is not blocked, so that the valve plate can perform the blocking and opening functions according to the vibration.
In addition, the outer edge of the first valve plate 501 is provided with a plurality of notches 501b, and the number of the notches 501b can be determined according to the number of the base through holes 505 b. The notch 501b and the base through hole 505b are at least partially overlapped in the conducting direction of the base through hole 505b, so that the first valve plate 501 only covers the base through hole 505b, and oil can directly flow to the base through hole 505b from the notch 501 b. When this valve sheet mechanism 50 is attached to the suspension base 40, the first chamber can communicate with the second chamber through the notch 501b, the base through hole 505b, provided that the first chamber and the second chamber separately formed are located on the upper side and the lower side of the valve base 505, respectively.
The damping generated by the valve plate mechanism 50 shown in fig. 4 is adjustable to achieve a suitable damping effect, and the principle is as follows:
1. first valve plate 501 sets up breach 501b, then when little amplitude appears, fluid flows through breach 501b, directly gets into the second chamber through base through-hole 505b, can obtain little damping.
At this moment, first valve plate 501 can set up to different models, for example, the breach 501b size of multiple first valve plate 501 is different, and breach 501b quantity is different to the regulation can be directly through the fluid flow of base through-hole 505 b. Therefore, the first valve plate 501 is mainly used for adjusting the damping of small amplitude, and different types of first valve plates 501 can be selected as required to achieve the required damping of small amplitude.
It can be understood that the purpose of the first valve plate 501 is to provide small amplitude damping, as long as the first valve plate 501 does not completely cover the base through hole 505b, so the first valve plate 501 is not limited to the structure provided with the notch 501 b. For example, the first valve plate 501 is a complete circular valve plate, but the outer edge of the first valve plate still has a distance from the edge of the base through hole 505b, so that a part of the base through hole 505b is exposed. Or, the first valve plate 501 covers all the base through holes 505b, but the periphery of the first valve plate 501 is provided with through holes, the through holes are opposite to part of the base through holes 505b, and oil can flow to the base through holes 505b from the through holes and then enter the second chamber, which is also a feasible scheme.
Of course, setting up breach 501b on the one hand can reach the direct flow through base through-hole 505b of fuel feeding liquid and then realize the production of small amplitude damping, and be difficult for receiving sheltering from of second valve block 502, still make first valve block 501 can be out of shape under the effect of less hydraulic pressure, shrink downwards to when following medium amplitude, fluid pushes away second valve block 502.
2. The covering area of the second valve plate 502 is smaller than that of the first valve plate 501, when the medium amplitude occurs, the hydraulic pressure of oil liquid is increased, then part of oil liquid in the first cavity flows into the second cavity through the notch 501b of the first valve plate 501 and the base through hole 505b, the other part of oil liquid pushes the second valve plate 502 away under the action of the hydraulic pressure (the first valve plate 501 is pushed away and contracted at the same time), the covered base through hole 505b is partially opened, and the oil liquid flows into the second cavity through the base through hole 505b, and the second valve plate 502 has higher rigidity compared with the first valve plate 501, so that the medium amplitude damping can be adjusted. The second valve plate 502 can be circular as shown in fig. 4, or can be other shapes.
The second valve plate 502 can be designed to have different types, for example, the second valve plate 502 has different thickness and different diameter, and different types of second valve plates 502 can be replaced by different types of second valve plates, or the number of the second valve plates 502 can be increased or decreased (which is equivalent to increasing or decreasing the thickness of the second valve plates 502). Damping at moderate amplitudes can be adjusted. In this embodiment, a support is further provided to provide a space for the second valve plate 502 to deform downward and contract, so that the support with different diameters or different heights can be replaced, the damping at medium amplitude can be adjusted, and the second valve plate 502 and the support can be adjusted at the same time to achieve a comprehensive adjustment. That is, the second valve plate 502 or the support member can be replaced independently, or the number of the second valve plate and the support member can be adjusted independently, so that different damping effects can be obtained.
3. For the base through hole 505b, when a large amplitude occurs, a large amount of oil can directly push the second valve plate 502 away, that is, the covering part can be completely opened, and the oil in the first chamber directly enters the second chamber through the base through hole 505 b. Damping at this time is mainly achieved by the flow restriction of the base through hole 505 b.
Therefore, different types of valve bases 505 can be designed, and the number and/or size of the base through holes 505b in different types of valve bases 505 can be different, so that the damping of the hydraulic suspension under large amplitude can be adjusted by replacing different types of valve bases 505.
According to the description, the damping of the hydraulic suspension can be controlled in multiple stages under different amplitudes, the control can be realized through different types of valve plate combinations or valve plate quantity adjustment, the valve plates with different models are changed only by parameters such as the size and the quantity of the notches 501b, the thickness and the rigidity of the valve plates, and the size and the quantity of the base through holes 505, the overall size of the valve plates and the position of the central hole are unchanged, so that the valve plates are convenient to disassemble and assemble, and the damping can be flexibly adjusted in stages. Therefore, the valve plate type hydraulic suspension changes the method that the damping is adjusted by changing the structure of the hydraulic module and manufacturing different sample pieces in the traditional hydraulic suspension, can independently replace and control the valve plate mechanism 50, and is very flexible in damping adjustment.
In the above embodiment, the first valve plate 501 and the second valve plate 502 of the valve plate mechanism 50 are located on the same side of the valve base 505, specifically, on the upper side of the valve base 505 in fig. 4, and during vibration, the oil is first driven to flow from top to bottom, that is, from the first chamber to the second chamber. It can be understood that first valve plate 501 and second valve plate 502 can be disposed on the lower side of valve base 505, or first valve plate 501 and second valve plate 502 can be disposed on different sides of valve base 505. When the first valve plate 501 and the second valve plate 502 are arranged on the lower side of the valve base 505 and oil flows from top to bottom, the oil firstly passes through the base through hole 505b and then flows out of the notch 501b under the condition of small amplitude; under the condition of medium amplitude, part of the air flows out through the through hole 505b of the base, part of the air flows out through the notch 501b, and part of the air flows out by pushing the second valve plate 502 open; at a large amplitude, the oil pushes the first valve plate 501 and the second valve plate 502 open directly and flows out. It can be understood that when the first valve plate 501 and the second valve plate 502 are disposed on the downstream side of the valve base 505, the valve plates deform outward, and have a sufficient deformation space, and no support member may be provided.
When the first valve plate 501 and the second valve plate 502 are disposed on different sides of the valve base 505, the principles under small, medium, and large amplitudes are basically similar, and the flow area is automatically adjusted according to different hydraulic pressures formed by different amplitudes, so as to provide the required damping, which is not described in detail again.
In addition, when the first valve plate 501 is disposed in the above embodiment, the base through hole 505b is not completely covered by the first valve plate, so that the damping adjustment with small amplitude is easily realized. However, it can be understood that it is also possible that the first valve plate 501 completely covers the base through hole 505b, at this time, the first valve plate 501 may be configured to have higher flexibility or elasticity, that is, may deform under the action of a small hydraulic pressure to open a part of the base through hole 505b, and may also achieve damping adjustment under a small amplitude, of course, the base through hole 505b is not completely covered, and the range of the small damping is wider. The valve plates are not limited to the first valve plate 501 and the second valve plate 502, a larger number of valve plates can be arranged, more damping grading adjustment can be achieved, and certainly, the two valve plates can meet the requirement of better damping grading adjustment and are easy to implement.
It should be noted that, the above description mainly describes that different damping is generated according to the amplitude when the oil flows in one direction, and it should be understood that when the oil flows back, obviously, the reverse oil hydraulic pressure also generates the back flow damping according to the setting of the valve plate. Still taking fig. 4 as an example, when the oil flows back from bottom to top, the oil can flow back through the base through hole 505b and the notch 501b, or according to the magnitude of the pressure of the return fluid, the first valve plate 501 and the second valve plate 502 are pushed away in reverse direction in order to partially or completely open the base through hole 505b, so as to generate different return damping.
With continued reference to fig. 4, the valve plate mechanism 50 may further include a spring 508. First valve plate 501 and second valve plate 502 are located on the same side of valve base 505, i.e., the upper side as viewed in fig. 4, and also on the upstream side of valve base 505 (the side through which oil passes), and spring 508 is provided on the other side. The valve plate is fastened to the valve base 505 by means of the fitting mounting bolts 506 and mounting nuts 503, the spring 508 is pre-compressed between the mounting bolts 506 and the valve base 505, and when the mounting nuts 503 are located on one side of the spring 508, the spring 508 may also be located between the mounting nuts 503 and the valve base 505. Proper return flow damping is readily achieved by the provision of the spring 508. By adjusting the stiffness and pre-load of the spring 508, the return flow damping can be adjusted.
In the embodiment of fig. 4, the valve plate mechanism 50 is disassembled and adjusted as follows:
1. loosening the main bolt 100 from the hydraulic mount, and separating the mount base 40 from the mount upper cover 10 of the hydraulic mount;
2. loosening the fastening bolt 507 for mounting the valve plate mechanism 50 on the suspension base 40, and detaching the valve plate mechanism 50;
3. by loosening the mounting bolts 506 of the valve plate mechanism 50, at least one of the first valve plate 501, the second valve plate 502, the valve base 505, the support plate 504, or the spring 508 can be replaced as needed to obtain the needed damping;
4. after replacement, the assembled valve plate, the spring 508 and the like are fixed and installed into the complete valve plate mechanism 50 by the installation bolt 506 and the installation nut 503;
