Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
The present embodiment relates to a hydraulic mount, as shown in fig. 1 in combination with fig. 2 to 4, which mainly includes a housing, a main rubber spring 3, a connecting member 3, a cup 13, a flow passage assembly, and a control member 14 in an integral structure.
The housing serves as a structural base for the entire hydraulic mount, and is not only used for carrying other components, but also for forming a press fit for the hydraulic mount on the external first component. The first component is typically the body of the vehicle, while the second component, described below, connected to the connecting element 3 corresponds to the drive train mounted on the body. Meanwhile, as an exemplary structural form, the housing of the embodiment also comprises an upper bracket 1 and a lower bracket 2 which are connected in a buckling manner from top to bottom, wherein flanges which are arranged in an outward-turning manner are formed at one end where the upper bracket 1 is connected with the lower bracket 2, the two flanges are attached to each other, the housing further comprises an outer bracket 6 which is sleeved outside the lower bracket 2, the top end of the outer bracket 6 is used for riveting the two attached flanges together to realize the fixation of the whole housing structure into a whole, and when the suspension is pressed, the outer bracket 6 is pressed on a vehicle body in an interference manner.
In this embodiment, the rubber main spring 4 and the cup 13 are fitted to the housing to form a liquid chamber in the suspension, and the flow path member is fixed in the liquid chamber, and is specifically composed of an upper flow path plate 8, a lower flow path plate 9, and a decoupling film 10, and a first flow path 11 for communicating the liquid chamber spaces on the upper and lower sides is formed in the flow path member. The connecting element 3, which is connected to the main rubber spring 4, is arranged to be exposed with respect to the housing, is generally of aluminium core construction and is used to form a connection between the hydraulic mount and an external second component, i.e. the drive unit.
The present embodiment is formed by the above housing, the rubber main spring 4, the connecting member 3, the cup 13 and the flow channel assembly, and particularly, the structure of the flow assembly with the spiral first flow channel 11 can be referred to the hydraulic suspension structure commonly used in the prior art, and the details thereof will not be described herein. As a main improvement of the hydraulic mount of this embodiment, a second flow channel 12 is further formed in the middle of the flow channel assembly, the second flow channel being through from top to bottom and being capable of communicating the liquid chamber spaces on the upper and lower sides, and a rigid control member 14 is fixedly connected to the middle of the cup 13 corresponding to the position of the second flow channel 12.
The control member 14 has a connection end extending outside the hydraulic mount to be connected to an external drive unit and is supported by the cup 13 in a natural state of the cup 13, and a top of the control member 14 may be directly or indirectly attached to form a block for the second flow passage 12. The second flow channel 12 is located in the center of the flow channel assembly and is disposed up and down through the upper flow channel plate 8 and the lower flow channel plate 9.
It should be noted that the above-mentioned direct blocking of the control member 14, i.e. the top of the control member 14 directly contacts the flow channel assembly to attach to the bottom of the flow channel assembly, forms a block for the second flow channel 12. The indirect blocking means that the top of the control member 14 contacts the flow channel assembly through other structures, so that the blocking of the second flow channel is formed by attaching the other structures on the top of the control member 14 to the bottom of the flow channel assembly.
In this embodiment, as a preferred embodiment, the control element 14 is configured to indirectly close the second flow channel 12, and in this case, the leather cup 13 is configured to at least partially cover the top end surface of the control element 14 facing the second flow channel 12, and is supported by the leather cup 13, so that the covered top of the control element 14 forms a close-off of the second flow channel 12 by attaching.
Through the cladding of leather cup 13 part to control 14 top, the elasticity characteristics that can utilize the leather cup 14 material to have to closely butt with the runner subassembly, and then leakproofness when guaranteeing the shutoff. In this case, to ensure reliable sealing, the thickness of the leather cup 13 covering the top end surface of the control member 14 should generally be not less than 1.5mm, for example, 1.5mm, 1.6mm, 2mm, etc. may be selected.
In this embodiment, the second flow channel 12 is preferably designed as a circular hole, the top of the corresponding control member 14 is also circular, and the diameter of the circular top of the control member 14 can be twice as large as the diameter of the second flow channel 12 in terms of structural design. Through the design of the diameter of the top of the control part 14, the sealing effect during plugging can be further ensured on the basis of the coating of the leather cup 13, and meanwhile, the stability of the top of the control part 14 with the larger diameter can be certainly improved when the top of the control part is abutted against the bottom of the runner assembly.
In this embodiment, as a preferred embodiment, the top of the housing is also provided with a position-limiting pad 5 sleeved on the connecting member 3, the position-limiting pad 5 can form a partial covering for the top of the housing as shown in fig. 1, and a clearance fit is preferably adopted between the position-limiting pad 5 and the outer peripheral surface of the connecting member 3, so that not only can a Z-direction clearance after the vehicle is suspended and installed be ensured, but also the motion load of the rubber main spring 4 can be relieved, and at the same time, the vibration isolation function can be provided to a certain extent, and a double vibration isolation structure is formed with the rubber main spring 4.
For the above clearance fit between the spacing pad 5 and the outer peripheral surface of the connecting member 3, the clearance therebetween may be, for example, 0.5mm, or it may take other values smaller or slightly larger. In addition, in order to effectively relieve abnormal noise generated by sudden pressure change at the upper part and the lower part of the liquid chamber during suspension movement, the embodiment is a further improved form, wherein an outer convex end extending into the liquid chamber is also formed on the rubber main spring 4, particularly the bottom of the rubber main spring 4, and a spoiler disc 7 transversely arranged in the liquid chamber is arranged on the outer convex end. The part of the middle part of the turbulence disc 7 connected with the rubber main spring 4 is arranged in a protruding way, and the turbulence disc and the rubber main spring 4 can be fixedly connected together through riveting or other methods.
The cup 13 at the bottom of the suspension in this embodiment may adopt a cup structure commonly used in the existing hydraulic suspension, but in order to facilitate the up-and-down repeated movement of the cup 13 during the large displacement of the suspension, as a further improvement, a small corrugated portion x and a large corrugated portion d which are nested and arranged and are concave downward are also constructed on the cup 13 from inside to outside along the radial direction of the cup 13. Wherein, the depth s and the width k of the top opening of the large corrugated part d are both larger than the small corrugated part x, and are generally at least 3-5 times of the small corrugated part x, and for the large corrugated part d, the depth s of the large corrugated part d is also larger than the width k of the top opening of the large corrugated part d.
It should be noted that, for the second flow channel 12 disposed on the flow channel assembly, the aperture size of the through hole structure affects the dynamic stiffness and damping performance of the suspension. Through relevant experiments and analysis, the inventor finds that the hydraulic suspension under the structure of the embodiment has a variation trend between the aperture of the second flow passage 12 and the dynamic stiffness (k) and damping performance of the suspension as shown in fig. 5, wherein the damping performance is expressed by a damping angle (deg). Based on this, in the actual design, the aperture of the second flow channel 12 can be selected according to the design requirement of the suspension product, and for the current compact SUV and other vehicle types, for example, the aperture of the second flow channel 12 can be between 13mm and 15 mm.
Through the arrangement of the second flow channel 12 and the control element 14 corresponding to the second flow channel, the second flow channel can be controlled to open and close according to external vibration excitation, so that the hydraulic suspension can meet the requirements of various dynamic characteristics, and the suspension performance can be adjusted based on the road condition, so that the use performance of the hydraulic suspension can be improved.
The specific application of the hydraulic suspension of the present embodiment will be described with reference to the description of the hydraulic suspension system of the vehicle in the second embodiment.
Example two
The embodiment relates to a vehicle hydraulic suspension system, as shown in fig. 6, which comprises a suspension unit 100 formed by the hydraulic suspension in the first embodiment, a driving unit 17 connected with the connecting end of a control member 14 in the hydraulic suspension, an acquisition unit 16 for acquiring the frequency of vibration excitation applied to the vehicle, and a control unit 15 for receiving the acquisition signal of the acquisition unit 16 to control the driving unit 17 to act and output linear driving force.
When the control unit 15 controls the driving unit 17 to operate, the control member 14 is subjected to a linear driving force and can reciprocate to open or close the second flow passage 12, so that the hydraulic suspension performance can be adjusted.
The above-mentioned acquisition unit 16 generally uses an acceleration sensor disposed on the vehicle, the control unit 15 can be integrated into the vehicle controller, and the driving unit 17 uses, for example, a solenoid valve or other components acting in a straight line.
When the vehicle hydraulic suspension system of the embodiment is used, a specific control method comprises the following steps:
step s 1: acquiring, by an acquisition unit 16, the frequency of the vibration excitations to which the vehicle is subjected during travel;
step s 2: the control unit 15 compares the collected vibration-excited frequency signals, controls the driving unit 17 to operate to open the second flow channel 12 if the frequency signals are above a preset calibration value, and controls the driving unit 17 to operate to block the second flow channel 12 if the frequency signals are less than the preset calibration value;
and, step s 3: the above steps s1-s2 are repeated.
The calibration value preset in the control unit 15 can be selected according to the design requirements and experience of the whole vehicle, and by adopting the control process, the performance of the hydraulic suspension system when the second flow passage 12 is opened and blocked is shown in fig. 7, wherein k open and deg open indicate that the second flow passage 12 in the suspension is opened, and k closed and deg closed indicate that the second flow passage 12 is blocked. In addition, as can be seen from fig. 7, by controlling the opening and closing of the second channel 12, the dynamic characteristic and the damping characteristic of the suspension can be improved, and when the second channel 12 is opened, the dynamic stiffness of the suspension tends to decrease, and the damping peak frequency also moves backwards.
The adoption of the hydraulic suspension of embodiment one can control the suspension performance according to the vibration excitation signal who gathers through the embodiment one, can adapt to multiple dynamic characteristic's needs, promotes the suspension result of use, and has fine practicality.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
