Description

Technical Field

[0001] This application relates to vehicle component technology, and more particularly to a thrust rod connecting bracket, a vehicle suspension system, and a vehicle. Background Technology

[0002] In the design and manufacture of heavy-duty trucks, the thrust rod is a key component connecting the axle and the frame. Its main function is to transmit the longitudinal force of the axle to the frame, ensuring stable power transmission and structural stability during vehicle operation.

[0003] In related technologies, thrust rods are typically connected to the longitudinal or transverse beams of the vehicle frame via connecting brackets. The complex driving paths of vehicles, coupled with the concentrated load distribution between the connecting brackets and the longitudinal or transverse beams of the frame at their connection points, result in limited connection strength between the connecting brackets and the frame. Under long-term use, the connection points between the connecting brackets and the longitudinal or transverse beams of the frame are prone to fatigue fracture, affecting vehicle safety. Utility Model Content

[0004] This application provides a thrust rod connecting bracket, a vehicle suspension system, and a vehicle to solve the technical problem of limited connection strength between the thrust rod connecting bracket and the vehicle frame in related technologies.

[0005] On one hand, this application provides a connecting bracket for a thrust rod, comprising:

[0006] Mounting components are used to connect to the lower wing end of the frame;

[0007] Two extensions are connected to the mounting component. The two extensions are located on opposite sides of the mounting component. One of the two extensions is used to connect to the front connecting beam of the frame, and the other of the two extensions is used to connect to the first crossbeam of the frame.

[0008] An installation gap is formed between the two extension members, the installation gap being configured to accommodate at least a portion of the connection ends of the first and second longitudinal thrust rods of the frame, and the two extension members being used to connect to the connection ends of both the first and second longitudinal thrust rods.

[0009] In some possible implementations, the extension includes an extension body and a mounting portion connected to the extension body, the extension body being connected to the mounting portion, and at least one connecting portion being provided on the side of the extension body facing away from the mounting gap;

[0010] The connecting portion on one of the two extensions is used to connect with the front connecting beam, and the connecting portion on the other of the two extensions is used to connect with the first crossbeam.

[0011] In some possible implementations, the extension body is provided with a connecting hole, and the connecting holes on the two extensions are coaxially arranged along the width direction of the frame. Both connecting holes are used to pass through the first snap-fit ​​portion for installing the first longitudinal thrust rod.

[0012] In some possible implementations, the mounting portion is provided with positioning holes, the axis of which is located on the two mounting portions extends along the length direction of the frame, and the two positioning holes are configured to be correspondingly connected to the second snap-fit ​​portion of the second longitudinal thrust rod by a fastener that passes through them.

[0013] In some possible implementations, the extension body gradually tapers along the side opposite to the mounting member; the two extensions are arranged symmetrically relative to the mounting member.

[0014] On the other hand, this application provides a vehicle suspension system including a connecting bracket for the thrust rod as described in any of the preceding claims. The connecting bracket connects the vehicle frame and the first longitudinal thrust rod and the second longitudinal thrust rod, and the ends of the first longitudinal thrust rod and the second longitudinal thrust rod opposite to the connecting bracket are used to connect to the axle.

[0015] In some possible implementations, it also includes:

[0016] An airbag assembly includes an airbag base and an airbag component disposed on the airbag base, wherein the airbag base is connected to the axle;

[0017] The thrust rod assembly includes a first longitudinal thrust rod and a second longitudinal thrust rod arranged sequentially along the height direction. One end of the first longitudinal thrust rod and the second longitudinal thrust rod are connected to the airbag base, and the other end of the first longitudinal thrust rod and the second longitudinal thrust rod are connected to the connecting bracket.

[0018] In some possible implementations, the airbag base has two support brackets on the side facing the guide arm bracket, and the support brackets are connected to the first longitudinal thrust rod and the second longitudinal thrust rod in a one-to-one correspondence.

[0019] In some possible implementations, it also includes:

[0020] A shock absorber assembly includes a shock absorber and a mounting bracket disposed at the end of the shock absorber, wherein the shock absorber is connected to the airbag base and the mounting bracket is connected to the vehicle frame;

[0021] The stabilizer bar assembly includes a stabilizer seat connected to the axle and a stabilizer bar passing through the stabilizer seat, wherein the stabilizer seat is connected to the airbag base;

[0022] The suspension assembly includes a suspension component and a suspension bracket disposed at one end of the suspension component, the suspension bracket being connected to the vehicle frame, and the suspension component being connected to the stabilizer bar;

[0023] The lateral push rod assembly includes a lateral push bracket connected to the vehicle frame, a lateral push rod and a crossbeam disposed on the lateral push bracket, and a height detection element and a solenoid valve element connected to the airbag component are disposed on the crossbeam.

[0024] In another aspect, this application provides a vehicle including a connecting bracket for the thrust rod as described in any of the preceding claims, or a vehicle suspension system as described in any of the preceding claims.

[0025] The thrust rod connecting bracket provided in this application is connected to the lower wing end of the frame via a mounting component. One of the two extensions is used to connect to the front connecting beam of the frame, and the other of the two extensions is used to connect to the first crossbeam of the frame. Thus, the connection load between the connecting bracket and the frame is distributed to different structural components of the connecting bracket, which helps to avoid local stress concentration between the connecting bracket and the frame and avoids the problem of fatigue fracture caused by excessive stress due to a single connection point between the connecting bracket and the frame.

[0026] In addition, an installation gap is formed between the two extensions, which accommodates the connection end of the longitudinal thrust rod. This eliminates the need for additional connectors or extension structures to fix the longitudinal thrust rod, achieving a compact design for the connecting bracket and the longitudinal thrust rod. It also avoids interference between the longitudinal thrust rod and other components on the vehicle, improving space utilization. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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 limitations on this application.

[0044] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0045] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0046] As mentioned in the background section, traditional longitudinal thrust rod connecting brackets are typically connected to the longitudinal beams or cross beams of the vehicle frame. This single-connection-point method is structurally simple, but during vehicle operation, especially under complex road conditions, the longitudinal force transmitted by the longitudinal thrust rod can cause significant stress concentration at the connection point between the connecting bracket and the vehicle frame. Long-term use may lead to fatigue fracture at the connection point, and even endanger the safety of the vehicle.

[0047] In addition, due to the limited connection points between the thrust rod connecting bracket and the frame in traditional designs, the load is often concentrated in a limited area, resulting in uneven load distribution between the connecting bracket and the frame. This can easily accelerate the wear of the connecting bracket, affect its service life, and increase unnecessary inspection and maintenance costs.

[0048] Based on the above description of the relevant technologies, one or more embodiments of this application provide a thrust rod connecting bracket, a vehicle suspension system, and a vehicle. The following describes the solutions of the embodiments of this application in conjunction with the accompanying drawings.

[0049] like Figure 1 and Figure 2As shown, this application embodiment provides a thrust rod connecting bracket, including a mounting member 100 and two extension members 200. The mounting member 100 is used to connect to the lower wing end of the frame; both extension members 200 are connected to the mounting member 100 and are located on opposite sides of the mounting member 100. One of the two extension members 200 is used to connect to the front connecting beam of the frame, and the other of the two extension members 200 is used to connect to the first crossbeam of the frame; wherein, a mounting gap 300 is formed between the two extension members 200, and the mounting gap 300 is configured to accommodate at least a portion of the connecting ends of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 of the frame, and both extension members 200 are used to connect to the connecting ends of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510.

[0050] As can be seen from the above description, the thrust rod connecting bracket of this application embodiment is connected to the lower wing end of the frame through the mounting member 100. Of the two extension members 200, one extension member 200 is used to connect to the front connecting beam of the frame, and the other extension member 200 is used to connect to the first crossbeam of the frame. Thus, the connection load between the connecting bracket and the frame is distributed to different structural components of the connecting bracket, which helps to avoid local stress concentration between the connecting bracket and the frame and avoids the problem of fatigue fracture caused by excessive stress due to the connecting bracket and the frame being connected through a single connection point.

[0051] In addition, an installation gap 300 is formed between the two extensions 200. The installation gap 300 accommodates the connection ends of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510. There is no need to design additional connectors or extension structures to fix the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510. This achieves a compact connection design between the connecting bracket and the two longitudinal thrust rods, and also avoids interference between the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 and other components on the vehicle, thereby improving space utilization.

[0052] In some embodiments, the mounting member 100 is provided with a row of spaced mounting bolts 101, which pass through the lower wing end of the frame and the mounting member 100, so that the mounting member 100 is connected to the lower wing end of the frame. Here, the mounting member 100 can be connected to the lower wing end of the crossbeam 903 or the lower wing end of the longitudinal beam of the frame. This embodiment of the application does not make an absolute limitation on this.

[0053] like Figure 1 As shown, the extension 200 includes an extension body 201 and a mounting part 202 connected to the extension body 201. The extension body 201 is connected to the mounting part 100. The side of the extension body 201 facing away from the mounting gap 300 is provided with at least two connecting parts 2011. The connecting part 2011 on one of the two extensions 200 is used to connect to the front connecting beam, and the connecting part 2011 on the other of the two extensions 200 is connected to the first crossbeam.

[0054] In the above embodiment, the extension 200 is provided on opposite sides of the mounting member 100. The cross-section of the mounting member 100 and the two extensions 200 is "U". In the actual installation state, one extension 200 of the connecting bracket is located on the opposite inner side of the frame, and the other extension 200 is located on the opposite outer side of the frame. Here, the inner and outer sides of the frame are described with reference to the width direction of the vehicle.

[0055] The connecting portion 2011 on the extension body 201 is a mounting component that connects to the front crossbeam or the first crossbeam of the vehicle frame. The connecting portion 2011 and the extension body 201 have a coaxial through-hole fastening hole. The connecting portion 2011, the extension body 201, and the first crossbeam on the vehicle frame are connected by a common through-hole fastener, or the connecting portion 2011, the extension body 201, and the front crossbeam on the vehicle frame are connected by a common through-hole fastener. The connecting portion 2011 is sandwiched between the extension body 201 and the first crossbeam or the front crossbeam of the vehicle frame, which can serve both as support and assembly abutment fixation, making the connection between the extension body 201 and the first crossbeam or the front crossbeam of the vehicle frame more secure.

[0056] Here, the position and number of connecting parts 2011 can be set according to actual installation requirements. For example, along the side away from the mounting member 100, two connecting parts 2011 are provided at intervals on the extension body 201. Each connecting part 2011 has two fastening holes arranged at intervals. Thus, the extension body 201 is connected to the front connecting beam or the first crossbeam of the frame by bolts passing through the connecting parts 2011. Of course, since the two extension members 200 are respectively connected to the front connecting beam and the first crossbeam of the frame, the position of the connecting parts 2011 on the extension body 201 corresponding to the two extension members 200 can be adjusted accordingly to adapt to the connection position of the front connecting beam or the first crossbeam of the frame.

[0057] The design of multiple connecting parts 2011 distributes the connection load between the extension 200 and the front connecting beam of the frame, and the connection load between the extension 200 and the first crossbeam of the frame, to different positions and areas. This allows the connecting bracket to form more connection points with the frame, which helps to avoid stress concentration between the connecting bracket and the frame and reduces the risk of fatigue fracture damage to the connecting bracket.

[0058] It should be noted that in this embodiment, the first crossbeam of the frame refers to the crossbeam at the very front of the frame. The first crossbeam is connected to the longitudinal beam of the frame to enhance the structural strength of the front end of the frame. The front connecting beam is the connecting beam at the front of the frame, located in front of the first crossbeam of the frame, and is used to connect the longitudinal beam of the frame and other components, such as bumpers and radiator brackets. In this embodiment, the mounting part 100 is used to connect to the lower wing end of the longitudinal beam of the frame.

[0059] like Figure 1 and Figure 2As shown, in some embodiments, the extension body 201 is also provided with a connecting hole 2012. The connecting holes 2012 on the two extensions 200 are coaxially arranged along the width direction of the frame. The connecting end of the first longitudinal thrust rod 500 is provided with a first snap-fit ​​part 501. The connecting hole 2012 is used to pass through and install the first snap-fit ​​part 501 of the first longitudinal thrust rod 500.

[0060] Generally, in heavy trucks and other commercial vehicles, the connection ends of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 are rotatable connection structures. The first snap-fit ​​part 501 includes a bushing 5011 or bushing that sleeves the end of the first longitudinal thrust rod 500, and a connecting shaft 5012 that passes laterally through the bushing 5011 or bushing. The connecting shaft 5012 of the first snap-fit ​​part 501 passes through the connecting holes 2012 of the two extension members 200 and is fixed to the extension members 200 by nuts and fasteners. Thus, the first longitudinal thrust rod 500 can rotate at a certain angle relative to the connecting bracket. This design is beneficial for adapting to different driving conditions of the vehicle.

[0061] Each of the two extension members 200 is provided with a connecting hole 2012. The coaxial axial direction of the two connecting holes 2012 is the width direction of the frame. This design facilitates the precise installation of the first longitudinal thrust rod 500 and the extension member 200, allowing the connecting end of the first longitudinal thrust rod 500 to smoothly pass into the connecting hole 2012. In addition, the two coaxially arranged connecting holes 2012 ensure that when the connecting end of the first longitudinal thrust rod 500 is under force, the load can be evenly distributed to the two spaced extension members 200, avoiding local stress concentration caused by uneven load distribution and enhancing the stability of the connecting bracket.

[0062] In this embodiment, the mounting part 202 is provided with a positioning hole 2021. The axis of the positioning hole 2021 extends along the length of the frame. The positioning hole 2021 is configured to be connected to the second snap-fit ​​part 511 of the second longitudinal thrust rod 510 by fasteners that pass through both of them.

[0063] In the above embodiment, the two positioning holes 2021 of the mounting part 202 are arranged parallel to each other along the length of the frame. The second snap-fit ​​part 511 of the second longitudinal thrust rod 510 can be configured with reference to the structure of the first snap-fit ​​part 501 mentioned above. The difference is that the connecting shaft 5012 that passes through the bushing 5011 or bushing in the second snap-fit ​​part 511 is provided with a through hole 5111. The connecting shaft 5012 that passes through the bushing 5011 or bushing in the second snap-fit ​​part 511 is fixed to the mounting part 202 by bolts that pass through the positioning hole 2021 and the through hole 5111, so that the connecting end of the second longitudinal thrust rod 510 is connected to the mounting part 202.

[0064] Furthermore, in order to facilitate the connection between the second snap-fit ​​part 511 and the mounting part 202 via bolt fasteners, the connecting shaft 5012 of the second snap-fit ​​part 511 is rectangular and flat at one end corresponding to the mounting part 202.

[0065] In some embodiments, the extension body 201 gradually retracts along the side opposite to the mounting member 100; the two extensions 200 are arranged symmetrically relative to the mounting member 100.

[0066] The extension body 201 gradually tapers along the side opposite to the mounting member 100, making the structure of the connecting bracket more compact. This minimizes the space occupied by the connecting bracket and prevents interference between the connecting bracket and other components such as the braking system and pipelines. The symmetrical arrangement of the two extension members 200 makes the force on the connecting bracket more balanced, avoiding unbalanced torque caused by structural asymmetry, thereby improving the stability and reliability of the vehicle.

[0067] It should be noted that there are generally two longitudinal thrust rods arranged vertically. The connecting hole 2012 on the extension body 201 and the connecting end of the first longitudinal thrust rod 500 are connected by a connecting shaft 5012 through which both are inserted. However, the extension body 201 gradually shrinks along the side away from the mounting member 100, and the actual load-bearing capacity of the lower end of the extension member 200 is relatively weak. Therefore, by setting a mounting part 202 at the lower end of the extension body 201, the mounting part 202 provides a larger support surface and a more stable load for the connecting end of the lower second longitudinal thrust rod 510, which helps to ensure the stable connection between the connecting bracket and the lower second longitudinal thrust rod 510.

[0068] like Figure 3 and Figure 4 As shown, another embodiment of this application also provides a vehicle suspension system, which includes a connecting bracket for the thrust rod as described in any of the above claims. The connecting bracket connects the vehicle frame and the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510. The ends of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 facing away from the connecting bracket are used to connect the axle.

[0069] Since the vehicle suspension system includes a thrust rod connecting bracket as described above, it has all the advantages of a thrust rod connecting bracket.

[0070] like Figure 3 As shown, the vehicle suspension system in this embodiment of the application further includes an airbag assembly and a thrust rod assembly. The airbag assembly includes an airbag base 401 and an airbag component 402 disposed on the airbag base 401. The airbag base 401 is connected to the axle. The thrust rod assembly includes a first longitudinal thrust rod 500 and a second longitudinal thrust rod 510 arranged sequentially along the height direction. One end of the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 are connected to the airbag base 401, and the other end is connected to the connecting bracket.

[0071] In the vehicle suspension system of this application embodiment, the airbag assembly and the thrust rod assembly jointly bear the load between the axle and the frame. The two longitudinal thrust rods transmit the thrust and reaction forces of the axle in the longitudinal direction, making the load distribution between the axle and the frame more uniform and avoiding local stress concentration caused by a single support point.

[0072] like Figure 5 As shown, in some embodiments, the airbag base 401 has two support brackets 403 on the side facing the guide arm bracket, and the support brackets 403 are connected to the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 in a one-to-one correspondence.

[0073] Here, the connection between the airbag base 401 and the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510 can refer to the aforementioned connection structure between the connecting bracket and the first longitudinal thrust rod 500 and the second longitudinal thrust rod 510. For example, it can be connected by fasteners that pass through the support bracket 403 and the connecting end of the first longitudinal thrust rod 500. The airbag base 401 actually connects the axle, the airbag, and the two longitudinal thrust rods. Therefore, this design eliminates the need for additional connecting parts to connect the axle, which is beneficial for achieving the integration and weight reduction of vehicle components.

[0074] like Figure 3 As shown, in some embodiments, the vehicle suspension system further includes:

[0075] The shock absorber assembly includes a shock absorber 601 and a mounting bracket 602 located at the end of the shock absorber 601. The shock absorber 601 is connected to the airbag base 401, and the mounting bracket 602 is connected to the vehicle frame.

[0076] The stabilizer bar assembly includes a stabilizer seat 701 connected to the axle and a stabilizer bar 702 passing through the stabilizer seat 701. The stabilizer seat 701 is connected to the airbag base 401.

[0077] The suspension assembly includes a suspension component 801 and a suspension support 802 located at one end of the suspension component 801. The suspension support 802 is connected to the vehicle frame, and the suspension component 801 is connected to the stabilizer bar 702.

[0078] The lateral push rod assembly includes a lateral push bracket 901 connected to the vehicle frame, a lateral push rod 902 and a crossbeam 903 mounted on the lateral push bracket 901, and a height detection component and a solenoid valve component connected to the airbag component 402 mounted on the crossbeam 903.

[0079] Here, a height sensor can be used to detect the relative height between the vehicle body and the axle. An electromagnetic valve is used to regulate the inflation and deflation of the airbag 402. Based on the vehicle height data fed back by the height sensor, the control system controls the inflation and deflation of the airbag via the electromagnetic valve, thereby adjusting the vehicle height. Of course, the specific connection lines and principles of the height detection device and electromagnetic valve to the vehicle can be referenced in the suspension system design of heavy trucks in related technologies, and will not be elaborated further in this embodiment.

[0080] In some embodiments, the thrust rod assembly has two symmetrically arranged along the width direction of the vehicle frame. Each thrust rod assembly includes a first longitudinal thrust rod 500 and a second longitudinal thrust rod 510, which are arranged vertically. Correspondingly, the connecting brackets for the airbag assembly and the thrust rods are provided in two symmetrically arranged positions.

[0081] The vehicle suspension system in this embodiment, through the coordinated action of components such as the shock absorber assembly, stabilizer bar assembly, suspension assembly, and pushrod assembly, can better cope with various complex operating conditions and load changes during vehicle operation. These components cooperate with each other in multiple dimensions, including vertical, longitudinal, and lateral directions, to jointly ensure a stable connection and load transfer between the axle and the frame, thereby improving the overall performance of the vehicle.

[0082] This application also provides a vehicle, including a connecting bracket for the thrust rod as described in any of the above claims, or a vehicle suspension system as described in any of the above claims.

[0083] Since the vehicle includes the thrust rod connecting bracket of any of the preceding claims, or the vehicle suspension system as described in any of the preceding claims, it possesses all the advantages of both the thrust rod connecting bracket and the vehicle suspension system. Further details regarding this will not be elaborated upon in the embodiments of this application.
