Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of automobile equipment, and particularly relates to a damping support. BACKGROUND

[0002] The damping support is a damping and connecting support, which is connected between a power assembly of a vehicle and a frame of the vehicle, and is used for reducing vibration during driving of the vehicle and ensuring stability of driving of the vehicle.

[0003] In the related art, the damping support mainly comprises a beam, and the power assembly and the frame are fixedly connected through the beam.

[0004] However, during driving of the vehicle, vibration generated at the power assembly is transmitted to the frame through the beam, so that the frame vibrates. Since the beam has poor damping capacity, vibration in the frame cannot be eliminated, and thus the vehicle cannot be stably driven. SUMMARY

[0005] The damping support provided by the present disclosure can reduce vibration during driving of the vehicle and improve stability of driving of the vehicle. The technical solution is as follows.

[0006] The damping support provided by the present disclosure comprises a support fork and a damping assembly. The support fork comprises a connecting piece and at least two fork arms, the fork arms are arranged at intervals, and the ends of the fork arms are connected to the connecting piece. The fork arms are elastic members, which can reduce vibration of the support fork through their elasticity. In addition, the damping assembly comprises at least two main springs, each main spring corresponds to each fork arm, and the main spring is connected to the corresponding fork arm. The vibration of the damping support is further reduced through the elasticity of the main spring.

[0007] In one implementation manner of the present disclosure, the fork arm comprises an arc plate and a straight plate, one end of the arc plate is connected to the connecting piece, and the other end of the arc plate is connected to the straight plate. In this way, a U-shaped opening is formed between two adjacent fork arms, and the safe interval distance between the straight plates is ensured. When the main spring is inserted into the straight plate, the distance between the main springs is not too small to affect the connection between the damping support and the subframe.

[0008] In another implementation manner of the present disclosure, the fork arm has a containing hole, and the containing hole penetrates through opposite sides of the straight plate. Correspondingly, the damping assembly further comprises a sleeve, the sleeve is inserted into the containing hole, and the stability of the sleeve is improved. Then, the main spring is inserted into the sleeve to improve the strength of the connection between the main spring and the sleeve.

[0009] In still another implementation manner of the present disclosure, the main spring comprises an inner tube, an outer tube and a connecting rib. Firstly, the inner tube is inserted into the outer tube, and the connecting rib is located between the inner tube and the outer tube, so that the connecting rib is deformed under the action force when the inner tube and the outer tube are relatively displaced. Secondly, the connecting rib is connected with the inner tube and the outer tube respectively, so that the outer tube can be relatively displaced when the inner tube is displaced. Finally, the sleeve is sleeved on the outer tube, so that the connection between the main spring and the damping support is more convenient.

[0010] In still another implementation manner of the present disclosure, the connecting rib comprises a supporting ring and a plurality of elastic ribs, and each elastic rib is arranged along the circumference of the supporting ring, so that the outer tube can be limited to move in any direction by the elastic force of the supporting ring and each elastic rib when the inner tube and the outer tube are relatively displaced. Specifically, when the inner tube is inclined relative to the outer tube, the supporting ring and each elastic rib exert an elastic force on the inner tube, so that the inner tube is reset. Through repeated processes, the vibration can be attenuated to a certain extent. In addition, the inner tube is connected with the inner edge of the supporting ring, the outer wall of the inner tube is connected with each elastic rib, and the inner wall of the outer tube is connected with the outer edge of the supporting ring.

[0011] In still another implementation manner of the present disclosure, the inner tube, the supporting ring and the adjacent two elastic ribs have an air chamber. The air chamber has air inside, so that the damping efficiency of the damping assembly can be improved.

[0012] In still another implementation manner of the present disclosure, the damping assembly further comprises a connecting shaft, the connecting shaft is inserted into the inner tube, the outer wall of the connecting shaft is in interference fit with the inner wall of the inner tube, so that the connecting shaft and the inner tube are not easy to be loosened. In addition, the connecting shaft can be connected with the subframe, so that the damping support and the subframe are connected.

[0013] In still another implementation manner of the present disclosure, the damping assembly further comprises two gaskets, and the two gaskets are located on opposite sides of the straight plate. The gasket is sleeved on the outer wall of the inner tube, and the end surface of the gasket towards the straight plate is connected with the straight plate. Therefore, the gasket can be effectively fixed and is not easy to be loosened.

[0014] In a further implementation form of the present disclosure, the gasket has a plurality of protrusions, the plurality of protrusions are arranged along a circumferential direction of the gasket, and the length direction of the plurality of protrusions passes through the center of the gasket. The plurality of protrusions are arranged along the two end surfaces in the direction of the gasket axis, and can be connected to the straight plate and the auxiliary frame, respectively.

[0015] In a further implementation form of the present disclosure, the connecting member includes a support and at least two connecting arms. The connecting arms are arranged at intervals, and the ends of the connecting arms are connected to the support, respectively. The connecting arms are connected to the power assembly in the vehicle, and the support is connected to the fork arms which are connected to the auxiliary frame, so that the power assembly in the vehicle is connected to the auxiliary frame. The support and the connecting arms have the connecting holes, and the connecting holes can improve the stability of the connection between the connecting arms and the power assembly in the vehicle.

[0016] The technical scheme provided by the embodiments of the present disclosure has at least the following beneficial effects:

[0017] The power assembly in the vehicle is connected to the connecting member in the damping support, the connecting member is connected to the fork arms, and the fork arms are connected to the auxiliary frame of the vehicle.

[0018] The vibration generated by the power assembly is transmitted to the connecting member via the power assembly, and then transmitted to the fork arms via the connecting member. Since the damping support has at least two fork arms, both of which are elastic members and are kept at a certain distance from each other, when the vibration is transmitted to the two fork arms, the two fork arms can reduce the vibration frequency by their elasticity, thereby weakening the transmission of the vibration. In addition, the fork arms are connected to the damping assembly, and the main spring of the damping assembly can further reduce the vibration, thereby reducing the vibration transmitted to the auxiliary frame and not affecting the stability of the vehicle.

[0019] The vibration generated by the wheels is transmitted to the auxiliary frame, and then transmitted to the main spring and the two fork arms via the auxiliary frame. The main spring and the two fork arms can reduce the vibration by their elasticity, thereby reducing the vibration transmitted to the power assembly and not affecting the stability of the power assembly.

[0034] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the drawings.

[0035] The embodiments of the present disclosure provide a damping support. Figure 1 is a structural schematic view of the damping support, see Figure 1In the embodiment, the damping support includes a support fork 1 and a damping assembly 2. The support fork 1 includes a connecting piece 11 and at least two fork arms 12. The fork arms 12 are arranged at intervals. The ends of the fork arms 12 are connected to the connecting piece 11. The fork arms 12 are elastic members. The damping assembly 2 includes at least two main springs 21. The main springs 21 correspond to the fork arms 12. The main springs 21 are connected to the fork arms 12.

[0036] The power assembly in the vehicle is connected to the connecting piece 11 in the damping support. The connecting piece 11 is connected to the fork arms 12. The fork arms 12 are connected to the subframe of the vehicle.

[0037] The vibration generated at the power assembly is transmitted to the connecting piece 11 through the power assembly and then transmitted to the fork arms 12 through the connecting piece 11. Since the damping support has at least two fork arms 12, both of which are elastic members, and the two fork arms 12 are kept at a distance, when the vibration is transmitted to the two fork arms 12, the two fork arms 12 can reduce the vibration frequency through their elasticity, thereby weakening the transmission of the vibration. In addition, the fork arms 12 are connected to the damping assembly 2. The main springs 21 of the damping assembly 2 can further reduce the vibration, thereby reducing the vibration transmitted to the subframe and not affecting the stability of the vehicle.

[0038] The vibration generated at the wheels is transmitted to the subframe. The vibration is transmitted to the main springs 21 and the two fork arms 12 through the subframe. The main springs 21 and the two fork arms 12 can reduce the vibration through their elasticity, thereby reducing the vibration transmitted to the power assembly and not affecting the stability of the power assembly.

[0039] Exemplarily, the connecting mode between the connecting piece 11 in the damping support and the power system assembly in the vehicle is bolt connection. The bolt connection can improve the strength of the connection between the connecting piece 11 and the power system assembly in the vehicle. The damping support and the power system assembly in the vehicle are prevented from loosening, thereby improving the reliability and stability of the damping support.

[0040] Again referring to Figure 1 In the embodiment, the fork arm 12 includes an arc plate 121 and a straight plate 122. One end of the arc plate 121 is connected to the connecting piece 11. The other end of the arc plate 121 is connected to the straight plate 122, so that the adjacent two fork arms 12 form a U-shaped opening 1211. The main spring 21 is inserted into the straight plate 122.

[0041] Since the adjacent two arc plates 121 form the U-shaped opening 1211, the two straight plates 122 connected to the two arc plates 121 can always maintain a certain safety distance. The safety distance between the two straight plates 122 can accommodate the connecting end of the subframe, which is conducive to the connection of the subframe to the two straight plates 122.

[0042] Exemplarily, a straight plate 122 with elasticity and a main spring 21 are additionally arranged in the U-shaped opening 1211 formed by the two adjacent arc plates 121, and the main spring 21 is inserted into the straight plate 122. By inserting the connecting end of the auxiliary frame into the three main springs 21, the effect of the damping support on reducing vibration is improved.

[0043] Figure 2 FIG. 4 is a top view of the damping support, Figure 3 FIG. 5 is a structural schematic view of the sleeve 22, referring to Figure 2 and Figure 3 The fork arm 12 has a receiving hole 123 penetrating through opposite sides of the straight plate 122, and the damping assembly 2 further comprises a sleeve 22 inserted into the receiving hole 123, and the main spring 21 is inserted into the sleeve 22.

[0044] The sleeve 22 can protect the main spring 21. By inserting the sleeve 22 into the receiving hole 123 and inserting the main spring 21 into the sleeve 22, the stability of the main spring 21 is improved when the main spring 21 is subjected to external force.

[0045] Exemplarily, the sleeve 22 is made of steel, which has high hardness and strength, and has the characteristics of corrosion resistance, wear resistance, etc., so as to improve the stability of the main spring 21.

[0046] Figure 4 FIG. 6 is a front view of the main spring 21, Figure 5 FIG. 7 is a top view of the main spring 21, referring to Figure 4 and Figure 5 The main spring 21 comprises an inner pipe 211, an outer pipe 212 and a connecting rib 213, the inner pipe 211 is inserted into the outer pipe 212, the connecting rib 213 is located between the inner pipe 211 and the outer pipe 212, and the connecting rib 213 is connected to the inner pipe 211 and the outer pipe 212 respectively, and the sleeve 22 is sleeved outside the outer pipe 212.

[0047] The inner pipe 211 and the outer pipe 212 are connected by the connecting rib 213. By the connecting rib 213, the stability between the inner pipe 211 and the outer pipe 212 is improved, and the ability of the damping support to reduce vibration frequency is improved.

[0048] Exemplarily, the material of the connecting rib 213 can be rubber. Rubber has greater elasticity and can reduce the vibration between the inner pipe 211 and the outer pipe 212. When the connecting rib 213 made of rubber is deformed by external force, the direction of the external force is random and the size of the external force is constantly changing, so the connecting rib 213 will be stretched and compressed to different degrees. At this time, the connecting rib 213 can quickly recover through the characteristics of the rubber material, so that the inner pipe 211 can have a reset trend relative to the outer pipe 212. Therefore, during the relative movement between the inner pipe 211 and the outer pipe 212, the connecting rib 213 can continuously reduce the influence of vibration. At the same time, rubber also has good physical and chemical stability, which can improve the reliability of the main spring 21.

[0049] Exemplarily, the material of the inner pipe 211 can be rubber. Rubber has greater elasticity and can make the main spring 21 reduce the transmission of vibration in the damping support to a greater extent.

[0050] Alternatively, the material of the inner pipe 211 can also be metal. Metal has higher strength and can improve the stability of the main spring 21 in the connection between the damping support and the auxiliary frame.

[0051] Exemplarily, the material of the outer pipe 212 can be rubber. Rubber has greater elasticity and can make the main spring 21 reduce the transmission of vibration in the damping support to a greater extent.

[0052] Alternatively, the material of the outer pipe 212 can also be metal. Metal has higher strength and can improve the stability of the main spring 21 in the connection between the damping support and the auxiliary frame.

[0053] Again referring to Figure 5 The connecting rib 213 includes a supporting ring 2131 and a plurality of elastic ribs 2132. Each elastic rib 2132 is arranged along the circumference of the supporting ring 2131 and connected to the inner edge of the supporting ring 2131. The outer wall of the inner pipe 211 is connected to each elastic rib 2132, and the inner wall of the outer pipe 212 is connected to the outer edge of the supporting ring 2131.

[0054] Since one end of each elastic rib 2132 is connected to the inner edge of the supporting ring 2131 and the other end is connected to the outer wall of the inner pipe 211, the inner pipe 211 can be uniformly stressed when the inner pipe 211 is subjected to external force, thereby improving the stability of the inner pipe 211.

[0055] Continuing to refer to Figure 5 In this embodiment, the inner pipe 211, the supporting ring 2131, and the adjacent two elastic ribs 2132 have an air chamber 2133 therebetween.

[0056] The air bag cavity 2133 has air due to the hollow inside, and thus can shrink to a greater extent when the air bag cavity 2133 is subjected to the extrusion force from the inner pipe 211 and the outer pipe 212. When the air bag cavity 2133 is no longer subjected to external force, it can also restore. Thus, the air bag cavity 2133 has a greater elastic limit, which can improve the damping performance of the connecting rib 213.

[0057] Exemplarily, the connecting rib 213 includes a plurality of air bag cavities 2133, which can be distributed symmetrically along the axis of the inner pipe 211. When the inner pipe 211 and the outer pipe 212 are not subjected to external force, the inner pipe 211 will not displace relative to the outer pipe 212. When not subjected to external force, the main spring 21 can always keep the opening direction of the inner pipe 211 and the outer pipe 212 consistent, ensuring the axis direction of the connecting shaft 23 and the sleeve 22 consistent, and improving the stability of the damping support.

[0058] Exemplarily, the number of air bag cavities 2133 is four. The four air bag cavities 2133 are arranged at intervals along the outer wall of the inner pipe 211, and the included angle between adjacent two air bag cavities 2133 is ninety degrees. Such design can improve the stability between the inner pipe 211 and the outer pipe 212, and also can increase the damping performance of the main spring 21 through the four air bag cavities 2133.

[0059] Exemplarily, since the connecting shaft 23 is connected with the auxiliary frame and is inserted into the inner pipe 211, the inner pipe 211 is inserted into the outer pipe 212 and has the air bag cavity 2133 between the inner pipe 211 and the outer pipe 212, and the outer pipe 212 is inserted into the sleeve 22, when the vibration is transmitted along the fork arm 12 to the main spring 21 in the sleeve 22, the inner pipe 211 will displace relative to the outer pipe 212. At this time, the elasticity of the air bag cavity 2133 can continuously weaken the vibration, thereby improving the smoothness of the vehicle during driving.

[0060] Figure 6 For the structural diagram of the connecting shaft 23, see Figure 5 In the embodiment, the damping assembly 2 further includes a connecting shaft 23, which is inserted into the inner pipe 211, and the outer wall of the connecting shaft 23 is interference fit with the inner wall of the inner pipe 211.

[0061] Since the connecting shaft 23 is inserted into the inner pipe 211, the strength of the main spring 21 can be improved, and the stability of the damping support can be improved. And since the outer wall of the connecting shaft 23 is interference fit with the inner wall of the inner pipe 211, the connecting shaft 23 and the inner pipe 211 can be more closely connected, and are not easy to loosen, thereby improving the stability of the damping support.

[0062] Exemplarily, the damping assembly 2 has two connecting shafts 23, which are respectively inserted into the inner pipes 211 of the two main springs 21, and the two ends of the two connecting shafts 23 are respectively connected with the auxiliary frame fixing, so as to improve the stability of the damping bracket.

[0063] Exemplarily, the connecting mode between the connecting shaft 23 and the auxiliary frame can be welding. The welding can make the connection between the connecting shaft 23 and the auxiliary frame more closely, improve the strength of the connection between the connecting shaft 23 and the auxiliary frame, and improve the reliability of the damping bracket. Moreover, the welding is convenient for manual or machine operation, and improves the integrity and stiffness between the damping bracket and the auxiliary frame.

[0064] Exemplarily, the material of the connecting shaft 23 can be steel. The steel has higher hardness and strength, and has the characteristics of corrosion resistance and wear resistance, so as to improve the reliability of the damping bracket.

[0065] Figure 7 is a structural schematic view of the gasket 24, referring to Figure 6 In the embodiment, the damping assembly 2 further includes two gaskets 24, which are respectively located on the opposite sides of the straight plate 122, and the gasket 24 is sleeved on the outer wall of the inner pipe 211 and connected with the straight plate 122.

[0066] The gasket 24 can play a role of buffering and conducting, further reduces the transmission of vibration on the damping bracket, so as to improve the stability of the vehicle during driving.

[0067] Since the end face of the outer pipe 212 is flush with the accommodating hole 123, the outer wall of the gasket 24 connected with the straight plate 122 can be closely fitted, so as to improve the stability of the damping bracket.

[0068] Exemplarily, the gasket 24 is connected with the straight plate 122 through bolts. The bolt connection structure is simple and convenient, and can well fix the gasket 24 and the straight plate 122, prevent the gasket 24 from loosening, and improve the reliability of the damping bracket.

[0069] Exemplarily, the material of the gasket 24 can be rubber. The rubber has greater elasticity and wear resistance, and the gasket 24 made of rubber material can be more durable, so as to improve the service life of the gasket 24. Moreover, when the gasket 24 is deformed under the action of extrusion force, the gasket 24 can have the ability of rapid recovery, which is beneficial to reducing the transmission of vibration during driving of the vehicle through the gasket 24.

[0070] Optionally, the material of the gasket 24 can be metal, and the gasket 24 is connected with the straight plate 122 through welding. The gasket 24 made of metal material has greater strength and wear resistance, can be used for a long time, and is not easy to be damaged.

[0071] Again referring to Figure 7In the embodiment, the gasket 24 has a plurality of protrusions 241, which are arranged along the circumference of the gasket 24 and have a length direction passing through the center of the gasket 24.

[0072] The protrusions 241 can increase the elasticity of the gasket 24, improve the ability to reduce vibration, and improve the vibration reduction performance of the vibration reduction support.

[0073] For example, the material of the protrusions 241 can be rubber. Rubber has greater elasticity and wear resistance, so that the protrusions 241 can be more durable during use. Moreover, when the protrusions 241 are deformed by external force, the protrusions 241 have the ability to quickly recover, thereby benefiting the reduction of vibration by the protrusions 241.

[0074] Optionally, when the gasket 24 is made of metal, the protrusions 241 made of rubber are inserted into the gasket 24, and the protrusions 241 are in interference fit with the gasket 24.

[0075] In the embodiment, the connecting piece 11 includes a support 111, at least two connecting arms 112, and a plurality of connecting holes 113. The connecting arms 112 are arranged at intervals, and the ends of the connecting arms 112 are connected to the support 111. The support 111 is connected to the fork arm 12, and the support 111 and the connecting arms 112 each have a connecting hole 113.

[0076] Vibration can be transmitted to the vibration reduction support through the power assembly, and the power assembly and the vibration reduction support are fixedly connected through the connecting holes 113. The connecting holes 113 can improve the stability of the connection between the power assembly and the vibration reduction support.

[0077] For example, the number of connecting holes 113 is three. One connecting hole 113 is located on the support 111 and is close to the connection between the support 111 and the connecting arms 112. The other two connecting holes 113 are respectively located on the connecting arms 112 and are away from the connection between the connecting arms 112 and the support 111, so that the distribution shape of the three connecting holes 113 is a triangle. Moreover, the two connecting arms 112 are located in the same plane, and the plane where the support 111 is located is higher than the two connecting arms 112 compared with the horizontal plane, so that the three connecting holes 113 are arranged in a staggered manner. In this way, when the power assembly and the vibration reduction support are connected through the three connecting holes 113, the stability of the connection between the power assembly and the vibration reduction support can be further improved.

[0078] In some examples, a steel sleeve 1131 is arranged in the connecting hole 113, which can strengthen the connection strength between the power assembly and the connecting piece 11. The steel sleeve 1131 can disperse stress, thereby protecting the threads of the inner pipeline 211 and greatly improving the use stability of the bolt, thereby prolonging the service life of the vibration reduction support.

[0079] In addition, the connecting piece 11 can be made of elastic material. The fastening connection of the elastic material belongs to soft connection, and the torque attenuation of the soft connection is relatively serious. Therefore, the steel sleeve 1131 is embedded in the connecting hole 113, so as to eliminate the risk of torque attenuation.

[0080] Exemplarily, the end surface of the steel sleeve 1131 is not lower than the end surface of the connecting hole 113, so that the axial force of the bolt cannot be reduced by the influence of the elastic material such as plastic or sealing element, and the bolt cannot be loosened, and can be in a fastening state for a long time. If the end surface of the steel sleeve 1131 is lower than the end surface of the connecting hole 113, the contact area between the bolt and the connecting hole 113 will be embedded, which will reduce the axial force of the bolt, and further cause the bolt connection to be loosened.

[0081] Exemplarily, the steel sleeve 1131 is inserted into the connecting hole 113, and the steel sleeve 1131 is in interference fit with the connecting hole 113.

[0082] Figure 8 For the structural diagram of the steel sleeve 1131, refer to Figure 8 Exemplarily, the outer wall of the steel sleeve 1131 in the axial direction has an opening 11311. By providing the opening 11311, the applicability of the steel sleeve 1131 can be enhanced. During the insertion of the steel sleeve 1131 into the connecting hole 113, the extrusion force of the connecting hole 113 on the outer wall of the steel sleeve 1131 can make the steel sleeve 1131 shrink to the opening 11311 within a certain elastic limit of the steel sleeve 1131, and at the same time, the outer wall of the steel sleeve 1131 can also form a reaction force on the connecting hole 113, so as to make the connection between the steel sleeve 1131 and the connecting hole 113 more closely.

[0083] Exemplarily, the outer wall of the steel sleeve 1131 is galvanized. By galvanizing the outer wall of the steel sleeve 1131, the moisture resistance and corrosion resistance of the steel sleeve 1131 can be improved.

[0084] The above only describes optional embodiments of the present disclosure, and does not limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
