Detailed Description

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Referring to fig. 1, a hydraulic suspension runner assembly according to an embodiment of the present invention includes a runner plate 1 and a rubber diaphragm 2, the runner plate 1 is provided with a through hole along an axial direction, the rubber diaphragm 2 is fixedly disposed at the through hole, a runner 3 disposed around the through hole is formed by recessing an outer side surface of the runner plate 1, a first communication port 4 and a second communication port 5 which are respectively communicated with the runner 3 are respectively disposed on a top surface and a bottom surface of the runner plate 1, and the first communication port 4 and the second communication port 5 are respectively used for communicating with an upper liquid chamber and a lower liquid chamber of a hydraulic suspension.

Specifically, the hydraulic suspension runner assembly may include a runner plate 1 and a rubber diaphragm 2, the middle part of the runner plate 1 may be provided with a through hole, the rubber diaphragm 2 may be fixedly disposed at the through hole, and in this embodiment, the rubber diaphragm 2 and the runner plate 1 are vulcanized and bonded to be fixed into a whole. The whole flow channel plate 1 can be in a circular plate shape with a certain thickness, the outer side surface or the circumferential side surface of the flow channel plate is concavely provided with a flow channel 3, and the flow channel 3 can be formed in a grooving mode or other processing modes, is in a ring shape, and is arranged around the through hole.

The top surface and the bottom surface of the flow channel plate 1 may be provided with a first communication port 4 and a second communication port 5, respectively, and it should be noted that, when the flow channel plate 1 is disposed in the hydraulic mount, the surface of the flow channel plate 1 surrounding the flow channel 3 and contacting with the upper liquid chamber of the hydraulic mount is the top surface, and the corresponding surface contacting with the lower liquid chamber of the hydraulic mount is the bottom surface. The first communication port 4 and the second communication port 5 are communicated with the flow channel 3, and the first communication port 4 and the second communication port 5 are respectively communicated with the upper liquid chamber and the lower liquid chamber.

When the vehicle body is excited by low frequency and large amplitude, liquid in the hydraulic suspension flows back and forth between the upper liquid chamber and the lower liquid chamber through the flow channel 3, and larger along-distance energy loss and local energy loss are generated in the flowing process, so that a large damping effect is generated, and the hydraulic suspension is used for eliminating vibration of the vehicle; when the vehicle body is excited by high-frequency small amplitude, the liquid hardly flows through the flow channel 3 due to the large internal resistance of the flow channel 3 and the large liquid column inertia, but the damping effect is generated by the vibration deformation of the rubber diaphragm 2, so that the vibration of the power assembly is eliminated, and the rubber diaphragm 2 is opposite to the decoupling disc.

Therefore, since the rubber diaphragm 2 and the runner plate 1 are fixed into a whole, and liquid flows back and forth around the rubber diaphragm 2 during vibration, the rubber diaphragm 2 cannot collide with the runner plate 1, and therefore the problem of abnormal sound can be effectively improved.

Referring to fig. 1 to 4, in some embodiments, the hydraulic suspension runner assembly further includes a first disc 6 and a second disc 7, the first disc 6 and the second disc 7 are respectively located at two opposite sides of the rubber membrane 2 in an axial direction, the rubber membrane 2 is provided with a diversion hole 8, the diversion hole 8 is used for communicating the upper liquid chamber and the lower liquid chamber, and the first disc 6 and the second disc 7 are both movably connected with the rubber membrane 2, so that the first disc 6 and the second disc 7 move towards a direction approaching or separating from the rubber membrane 2.

Specifically, in the conventional hydraulic mount, when the vehicle body is excited by high-frequency amplitude, since the resistance in the inertia passage and the liquid column inertia are large, and the resistance of the decoupling disc slit is smaller than the resistance in the inertia passage, the liquid hardly flows through the inertia passage, flows through the decoupling disc slit, and at this time, the hydraulic mount has the characteristics of small damping and low rigidity. However, since the gap flow amount of the decoupling disc is small, when the excitation frequency of the vehicle body is gradually increased, the volume rigidity of the upper liquid chamber and the lower liquid chamber is increased sharply, so that the vibration reduction effect is reduced, and when the excitation frequency reaches the resonance frequency of the decoupling disc, for example, about 120Hz, the volume rigidity of the upper liquid chamber and the lower liquid chamber is maximized, so that the liquid chamber has the problem of high-frequency dynamic hardening during high-frequency small-amplitude excitation, so that the vibration reduction effect is reduced.

In this embodiment, the hydraulic suspension runner assembly may further include a first disc 6 and a second disc 7, where the first disc 6 and the first disc 6 may be of the same size and shape, and the first disc 6 and the second disc 7 may be located on two axially opposite sides of the rubber diaphragm 2, respectively, for example, the first disc 6 is located on a side of the rubber diaphragm 2 facing the upper liquid chamber, the second disc 7 is located on a side of the rubber diaphragm 2 facing the lower liquid chamber, and the rubber diaphragm 2 may be provided with a diversion hole 8, in this embodiment, a plurality of diversion holes 8 may be provided, and the diversion holes 8 may be communicated with the upper liquid chamber and the lower liquid chamber, preferably, four diversion holes 8 are provided, and the four diversion holes 8 are annularly arranged.

And the first disc 6 and the second disc 7 can be movably connected with the rubber diaphragm 2, and the axial clearance between the first disc 6 and the second disc 7 is larger than the thickness of the rubber diaphragm 2, in the following embodiment, the axial clearance between the first disc 6 and the second disc 7 also needs to consider the axial dimensions of the first protrusion 12 and the second protrusion 13, so as to ensure that the first disc 6 and the second disc 7 can move synchronously along the axial direction relative to the rubber diaphragm 2.

More specifically, when the vehicle body is excited by the amplitude, the first disc 6 and the second disc 7 may move in a direction approaching or separating from the rubber diaphragm 2, for example, when the hydraulic mount is subjected to downward force, the liquid in the upper liquid chamber flows into the lower liquid chamber, driving the first disc 6 to move in a direction approaching the rubber diaphragm 2, and the second disc 7 to move in a direction separating from the rubber diaphragm 2, and when the hydraulic mount is subjected to upward force, the liquid in the lower liquid chamber flows into the upper liquid chamber, driving the first disc 6 to move in a direction separating from the rubber diaphragm 2, and the second disc 7 to move in a direction approaching the rubber diaphragm 2.

When the automobile body is excited by low frequency large amplitude, the excitation amplitude is larger than the bonding amplitude of the first disc 6 and the second disc 7 and the rubber membrane 2, in the vibration process, the first disc 6 and the second disc 7 can be sequentially bonded with the rubber membrane 2 alternately, the diversion holes 8 are in a closed state, so that liquid hardly flows through the diversion holes 8, and flows back and forth between the upper liquid chamber and the lower liquid chamber mainly through the annular flow channel 3, larger along-distance energy loss and local energy loss are generated in the flowing process, and the hydraulic suspension generates a large damping effect for eliminating the vibration of the automobile.

When the car body is subjected to medium-high frequency excitation, the liquid in the upper liquid chamber and the lower liquid chamber can vibrate up and down, the internal resistance of the annular flow channel 3 and the inertia of the liquid column are larger, the resistance of the diversion holes 8 is smaller than the resistance in the annular flow channel 3, the excitation amplitude is smaller than the bonding amplitude of the first disc 6, the second disc 7 and the rubber diaphragm 2, the liquid hardly flows through the annular flow channel 3 and flows through the diversion holes 8, the flow quantity of the diversion holes 8 is larger than that of gaps of the decoupling disc, so that the volume rigidity of the upper liquid chamber and the lower liquid chamber is reduced, and the problem of high-frequency dynamic hardening of the upper liquid chamber and the lower liquid chamber is solved.

The side of the first disc 6 and the second disc 7 facing the rubber diaphragm 2 are both provided with second bulges 13, when the automobile body is excited by low frequency and large amplitude, the first disc 6 or the second disc 7 moves towards the direction close to the rubber diaphragm 2, the first bulges 12 can be contacted with the first disc 6 or the second disc 7, the second bulges 13 can be contacted with the rubber diaphragm 2, the contact area between the first disc 6 and the second disc 7 and the rubber diaphragm 2 can be reduced, and therefore the problem of rattling abnormal sound is further improved.
