Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a vehicle suspension assembly and a vehicle. Background Technology

[0002] Currently, the rear suspension used in highway tractors is basically leaf spring or air suspension. However, when these types of suspensions are used for container transshipment in ports, the containers are heavy and the impact force on the chassis when they fall is large, resulting in a high failure rate.

[0003] In addition, during port loading operations, the tractor unit is required to be able to enter and exit the ship's hold to load and unload cargo, so the tractor unit needs to be at a low height off the ground.

[0004] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art. The foregoing statements are only for providing background information related to this application and do not necessarily constitute prior art. Summary of the Invention

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0038] like Figures 1 to 3 As shown, in some embodiments of the vehicle suspension assembly provided by the present invention, the vehicle suspension assembly includes a support beam assembly 10, an axle assembly 20, a connecting component 30, and a thrust assembly 40. The axle assembly 20 is fixedly connected to the support beam assembly 10 through the connecting component 30, and the thrust assembly 40 is fixedly mounted on the support beam assembly 10. The axle assembly 20 and the thrust assembly 40 are fixedly connected.

[0039] In the embodiments provided by the present invention, the axle assembly 20 is fixedly connected to the support beam assembly 10, and the thrust assembly 40 is fixedly installed on the support beam assembly 10. The thrust assembly 40 is also fixedly connected to the axle assembly 20. Therefore, the suspension assembly can be made into a rigid structure, which is beneficial to improving the impact resistance of the suspension assembly and reducing the failure rate. Moreover, by setting the thrust assembly 40 connected to the support beam assembly 10 and the axle assembly 20, the structural stability of the suspension assembly can be significantly enhanced, which is also very helpful in reducing the failure rate of the suspension assembly.

[0040] In addition, compared with elastic suspensions such as leaf springs or airbags, the suspension assembly provided by the present invention has an overall rigid structure, which can effectively improve the compactness of the structure, thereby helping to reduce the ground clearance of the towing seat on the vehicle and meet the loading and unloading needs of port tractors.

[0041] In some embodiments, the axle assembly 20 and the thrust assembly 40 are arranged along the length of the support beam assembly 10. This arrangement avoids the thrust assembly 40 occupying the installation space of the axle assembly 20 on the support beam assembly 10, thus preventing it from affecting the installation stability of the axle assembly 20. It also avoids interference between the thrust assembly 40 and the axle assembly 20, optimizing the overall layout of the suspension assembly.

[0042] In some embodiments, the connecting component 30 includes a first connecting seat 31, a first connecting member 32, and a second connecting seat 33. The first connecting seat 31 is fixedly connected to the support beam assembly 10, and the axle assembly 20 is disposed between the first connecting seat 31 and the second connecting seat 33. The first connecting member 32 connects the first connecting seat 31, the axle assembly 20, and the second connecting seat 33.

[0043] By setting the first connecting seat 31, the first connecting member 32, and the second connecting seat 33, the connection stability between the axle assembly 20 and the support beam assembly 10 can be effectively improved.

[0044] like Figures 4 to 6As shown, in some embodiments, the first connecting seat 31 is provided with a first connecting hole 315, the axle assembly 20 is provided with a second connecting hole 21 and a third connecting hole 22, the second connecting seat 33 is provided with a fourth connecting hole 333, and the first connecting member 32 passes through the first connecting hole 315, the second connecting hole 21, the third connecting hole 22 and the fourth connecting hole 333 to connect the first connecting seat 31, the axle assembly 20 and the second connecting seat 33.

[0045] The connection between the first connecting seat 31, the axle assembly 20 and the second connecting seat 33 is achieved by using the structure of the first connecting piece 32 and the connecting hole, which can improve the convenience and reliability of the connection.

[0046] The first connecting member 32 can be a bolt, rivet, or pin, etc.

[0047] The second connecting hole 21 and / or the third connecting hole 22 are either circumferentially closed holes or circumferentially open holes.

[0048] Setting the second connecting hole 21 and / or the third connecting hole 22 as circumferentially closed holes can prevent the first connector 32 from accidentally falling out of the second connecting hole 21 and / or the third connecting hole 22, thereby improving the stability and reliability of the connection.

[0049] Setting the second connecting hole 21 and / or the third connecting hole 22 as circumferentially open holes facilitates the passage of the first connecting member 32, simplifies the manufacturing process, reduces structural modifications to the axle assembly 20, and helps maintain the structural integrity of the axle assembly 20.

[0050] The axle assembly 20 is provided with a slot 23 that connects the second connecting hole 21 and the third connecting hole 22, and the first connecting member 32 is disposed in the slot 23.

[0051] By setting the slot 23, a guide channel can be provided for the insertion of the first connector 32 during installation. At the same time, the position of the first connector 32 can be limited, which improves the stability of the first connector 32 after it is inserted and prevents the first connector 32 from falling off accidentally.

[0052] like Figure 4 As shown, in some embodiments, the first connecting seat 31 includes a first connecting plate 311 and a first support plate 312, a second support plate 313 and a third support plate 314 mounted on the upper surface of the first connecting plate 311. The first connecting plate 311 is connected to the axle assembly 20, and the second support plate 313 is connected between the first support plate 312 and the third support plate 314. The top surfaces of the first support plate 312, the second support plate 313 and the third support plate 314 are welded to the bottom surface of the support beam assembly 10.

[0053] By setting the first support plate 312, the second support plate 313 and the third support plate 314, the welding area between the first connecting seat 31 and the support beam assembly 10 can be increased as much as possible, thereby improving the stability of the connection.

[0054] In some embodiments, the second support plate 313 extends along the length direction of the support beam assembly 10, and the first support plate 312 and the third support plate 314 extend along the width direction of the support beam assembly 10.

[0055] By setting the extension direction of the second support plate 313 to be perpendicular to the extension directions of the first support plate 312 and the third support plate 314, the first support plate 312, the second support plate 313 and the third support plate 314 can form a cross structure. When connected to the support beam assembly 10, there are both transverse and longitudinal welding surfaces, which can optimize the stress of the weld and improve the stability of the welded connection.

[0056] In some embodiments, in the width direction of the support beam assembly 10, the top surface dimensions of both the first support plate 312 and the third support plate 314 are not less than the width of the welded portion on the bottom surface of the support beam assembly 10. This arrangement maximizes the length of the welded connection, thereby improving its reliability and stability.

[0057] like Figure 5 As shown, in some embodiments, the second connecting seat 33 includes a second connecting plate 331 and a third connecting plate 332. The second connecting plate 331 is connected to the axle assembly 20, and the third connecting plate 332 is installed at the bottom of the second connecting plate 331 and is connected to the thrust assembly 40.

[0058] By providing the second connecting plate 331, the second connecting seat 33 and the axle assembly 20 can be connected. By providing the third connecting plate 332, the second connecting seat 33 and the thrust assembly 40 can be connected.

[0059] In some embodiments, the thrust assembly 40 includes a thrust assembly body 41 and a fourth connecting plate 42. The thrust assembly body 41 is connected to the bottom of the support beam assembly 10, and the fourth connecting plate 42 connects the bottom of the thrust assembly body 41 and the bottom of the connecting assembly 30.

[0060] By setting the fourth connecting plate 42, the thrust assembly 40 and the connecting component 30 can be connected, thereby achieving a fixed connection between the thrust assembly 40 and the axle assembly 20.

[0061] like Figure 7 and Figure 8As shown, in some embodiments, the thrust assembly body 41 includes a connecting beam 411 and a first upright plate 412, a second upright plate 413 and two third upright plates 414 mounted on the connecting beam 411. The first upright plate 412 is arranged vertically, the second upright plate 413 is arranged obliquely, and the two third upright plates 414 are connected between the first upright plate 412 and the second upright plate 413. The third upright plate 414 is in the shape of a right trapezoid.

[0062] By setting the first upright plate 412, the second upright plate 413 and the two third upright plates 414, a box-shaped structure can be formed, which reduces weight while improving the overall structural strength of the thrust assembly body 41.

[0063] Meanwhile, the third upright plate 414 is in the shape of a right trapezoid, so that the cross-sectional area of ​​the end of the box structure connected to the support beam assembly 10 is smaller than the cross-sectional area of ​​the end connected to the connecting beam 411. Under the premise that the cross-sectional area of ​​the end connected to the support beam assembly 10 is limited due to the limited welding area of ​​the support beam assembly 10, the cross-sectional area of ​​the end connected to the connecting beam 411 can be increased, thereby improving the overall structural strength of the thrust assembly body 41.

[0064] like Figure 9 As shown, in some embodiments, the support beam assembly 10 includes a first support beam 11 and two second support beams 12, the second support beams 12 extending along the length of the support beam assembly 10, the first support beam 11 connecting the two second support beams 12, and the first support beam 11 and / or the second support beams 12 having a box-shaped structure.

[0065] By setting the first support beam 11 and / or the second support beam 12 as a box-shaped structure, the overall structural strength of the support beam assembly 10 can be improved while reducing weight.

[0066] In some embodiments, the first support beam 11 includes a base plate 111, a cover plate 112, and two first support plates 113 and two second support plates 114 disposed between the base plate 111 and the cover plate 112. The two second support plates 114 are disposed between the two first support plates 113. The base plate 111 is provided with mounting holes 115 and first weight-reducing holes 116. The mounting holes 115 are disposed between the first support plates 113 and the second support plates 114, and the first weight-reducing holes 116 are disposed between the two second support plates 114. The second support plates 114 have multiple bends.

[0067] By setting two first support plates 113 and two second support plates 114 between the base plate 111 and the cover plate 112, the space formed by the base plate 111 and the cover plate 112 can be supported, thereby improving the structural strength of the first support beam 11.

[0068] By setting the first weight-reducing hole 116, the overall weight of the first support beam 11 can be reduced.

[0069] By setting multiple bends in the second support plate 114, the mounting hole 115 and the first weight reduction hole 116 can be avoided, while the support area of ​​the second support plate 114 on the base plate 111 and the cover plate 112 can be increased.

[0070] like Figure 10 As shown, the second support beam 12 includes a first support portion 121 and a second support portion 122. The first support portion 121 is C-shaped, and the second support portion 122 is a plate-like structure. The second support portion 122 is installed at the opening of the first support portion 121, and the first support portion 121 and the second support portion 122 are connected to form a box-shaped structure.

[0071] The following is in conjunction with the appendix Figures 1 to 10 The structure of one embodiment of the vehicle suspension assembly of the present invention will be described as follows:
