Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension technology, and in particular to a rear suspension lateral push support and suspension structure. Background Technology

[0002] The main function of the suspension system is to transmit the forces and torques acting between the wheels and the axle, and to buffer the impacts and vibrations transmitted from uneven road surfaces to the axle or vehicle body, ensuring smooth vehicle operation. The rear suspension push mount is an important component of the dump truck's rear suspension system, playing a role in supporting and stabilizing the suspension. Its main purpose is to bear the lateral loads of the rear suspension during vehicle operation, maintain wheel alignment and stability, and ensure the vehicle's smoothness and handling.

[0003] Traditional rear suspension pushers are mostly single-plate structures, which fail to fully consider the vehicle's usage needs under different loads and operating conditions. Especially for high-performance vehicles or off-road vehicles, the design of the pushers may not be able to effectively adapt to the stress requirements under extreme conditions such as high-speed driving and sharp turns, resulting in deformation or damage to the supports. Utility Model Content

[0004] This utility model addresses the problem that current rear suspension push-arm supports are single-plate structures, which are prone to deformation and damage under large loads. It proposes a rear suspension push-arm support and suspension structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a rear suspension lateral push support, including a support base plate, a first connecting plate, and a second connecting plate. The support base plate is fixedly connected to the axle. The first connecting plate and the second connecting plate are fixed to the support base plate at a relative interval. The first connecting plate is provided with a lateral push mounting seat, which is used to install at least the lateral push. A side connecting plate assembly is connected between the first connecting plate and the second connecting plate, so that the first connecting plate, the second connecting plate, the support base plate, and the side connecting plate assembly enclose a closed frame structure.

[0007] Furthermore, the first connecting plate is provided with a bending part and a mounting part connected in sequence. The end of the bending part away from the mounting part is fixedly connected to the support base plate, and the mounting part is provided with a horizontal push mounting seat.

[0008] Furthermore, the transverse push mounting base includes two mounting tubes, which are symmetrically distributed at intervals in the mounting section, and the mounting tubes are connected to the transverse push through a fixing pin.

[0009] Furthermore, the first connecting plate has a clearance groove between the two mounting tubes to accommodate a portion of the transverse push.

[0010] Furthermore, the side connecting plate assembly is provided with a third connecting plate, a top connecting plate and a fourth connecting plate connected in sequence. One end of the third connecting plate and the fourth connecting plate is fixedly connected to the support base plate, and the top connecting plate is arranged opposite to the support base plate.

[0011] Furthermore, the cross-sectional dimensions of the first connecting plate, the second connecting plate, the third connecting plate, and the fourth connecting plate all gradually decrease outward from the base plate of the support along their respective extension directions.

[0012] Furthermore, the support base plate is provided with at least two spaced mounting components along the first direction, and each mounting component is provided with multiple mounting holes evenly spaced along the second direction. The mounting holes are connected to the axle by fixing pins, and the first direction and the second direction intersect.

[0013] Furthermore, the support base plate has locating pin holes between the two mounting components, which are used for positioning and mounting with the axle.

[0014] This utility model also provides a suspension structure, including an axle, a push rod body, and a rear suspension push support as described in any of the above. The support base plate is fixedly connected to the axle. The push rod body has a first ball pin and a second ball pin at both ends along its own axial direction. The first ball pin is connected to the axle, and the second ball pin is connected to the push rod mounting seat.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] This utility model forms a closed frame structure by enclosing the support base plate, the first connecting plate, the second connecting plate, and the side connecting plate assembly, which effectively improves the overall strength and rigidity of the support. The internal central frame structure can effectively transfer and offset the vertical load transmitted by the crossbar of the rear suspension, can bear a large load, and is not easily deformed, thus effectively improving the stability and service life of the support.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Example 1

[0026] Please see Figures 1-3 A rear suspension lateral pusher support includes a support base plate 310, a first connecting plate 320, and a second connecting plate 330. The support base plate 310 is fixedly connected to the axle 100. The first connecting plate 320 and the second connecting plate 330 are fixedly spaced relative to each other on the support base plate 310. The first connecting plate 320 is provided with a lateral pusher mounting seat 340, which is used to install at least a lateral pusher 200. A side connecting plate assembly is connected between the first connecting plate 320 and the second connecting plate 330, so that the first connecting plate 320, the second connecting plate 330, the support base plate 310, and the side connecting plate assembly enclose a closed frame structure.

[0027] In this embodiment, as Figure 1 , 2As shown, the support base plate 310 is a rectangular plate structure. During installation, the support base plate 310 is vertically fixed to the axle 100. A first connecting plate 320 and a second connecting plate 330 are fixed to the opposite end of the support base plate 310 connected to the axle 100. Both the first connecting plate 320 and the second connecting plate 330 are plate structures. The planes extending from the first connecting plate 320 and the second connecting plate 330 are perpendicular to the plane of the support base plate 310. The first connecting plate 320 and the second connecting plate 330 are spaced apart along the length of the support base plate 310. The first connecting plate 320 and the second connecting plate 330 are parallel, so that there is a certain gap between the first connecting plate 320 and the second connecting plate 330. A side connecting plate assembly is fixedly connected between the first connecting plate 320 and the second connecting plate 330 along the periphery, so that the support base plate 310, the first connecting plate 320, the second connecting plate 330 and the side connecting plate assembly form a closed frame structure with a hollow interior. In addition, the first connecting plate 320 is provided with a horizontal push mounting seat 340. In use, one end of the horizontal push 200 can be connected to the horizontal push mounting seat 340.

[0028] In the above structure, by enclosing the support base plate 310, the first connecting plate 320, the second connecting plate 330 and the side connecting plate assembly to form a closed frame structure, the overall strength and rigidity of the support are effectively improved. The internal frame structure can effectively transfer and offset the load when subjected to the vertical load of the rear suspension transmitted by the crossbar. It can bear a large load and is not easily deformed, thus effectively improving the stability and service life of the support.

[0029] In the specific structure of the first connecting plate 320, such as Figure 1 As shown, the first connecting plate 320 has a bent portion 321 and a mounting portion 322 connected in sequence. The end of the bent portion 321 away from the mounting portion 322 is fixedly connected to the support base plate 310. The mounting portion 322 has a transverse push mounting seat 340. The transverse push mounting seat 340 includes two mounting tubes, which are symmetrically distributed at intervals in the mounting portion 322. The mounting tubes are connected to the transverse push 200 by a fixing pin. The first connecting plate 320 has a clearance groove 323 between the two mounting tubes to accommodate part of the transverse push 200.

[0030] In this embodiment, the first connecting plate 320 is provided with a bent portion 321 and a mounting portion 322 connected along its own extension direction. The first connecting plate 320 is located above the second connecting plate 330. One end of the bent portion 321 is fixedly connected to the support base plate 310. Along the extension direction of the bent portion 321, there is a downward bend. The other end of the bent portion 321 is fixedly connected to one end of the mounting portion 322. A transverse push mounting seat 340 is provided on the mounting portion 322, so that the first connecting plate 320 has a downward bend portion 321 along its own extension direction, which can effectively avoid the transverse push 200, facilitate the connection with the transverse push 200, and make the structure more compact. In addition, the bent portion 321 can effectively increase the bending resistance of the support. Since the transverse push 200 mainly transmits the vertical load to the support, the downward bend portion 321 can effectively distribute the load and improve the structural strength.

[0031] In addition, such as Figure 1 As shown, the lateral thrust mounting base 340 includes two mounting tubes, which are spaced apart along the extension direction of the first connecting plate 320. The spacing between them is determined by the length of the ball pin of the lateral thrust 200 to be connected. Both mounting tubes extend along the width direction of the support base plate 310. During installation, the ball pin and the mounting tube can be connected by a fixing pin, which can be a bolt. The bolt is passed through the ball pin and the mounting tube in sequence, and a nut is installed at the other end of the mounting tube for fixation. The connection structure is simple. This connection structure provides a foundation for support and fixation through two cylindrical mounting tubes. One end of the cylinder is used to fix the ball pin of the lateral thrust 200 lever, and the other end is used to place the bolt. This ensures that the support can flexibly adapt to the force transmission in the suspension system under dynamic loads, while ensuring the stable connection of the lateral thrust 200 lever, effectively providing lateral thrust, and ensuring that the thrust lever can effectively transmit and disperse impact force and vibration.

[0032] Specifically, the first connecting plate 320 near the end of the transverse pusher 200 has a relief groove 323 between the two mounting tubes. The relief groove 323 can be a C-shaped structure or a U-shaped structure. When the transverse pusher 200 is installed, it can accommodate part of the transverse pusher 200, thereby making the structure more compact. In addition, the relief groove 323 can also improve the force distribution ability and further improve the structural strength.

[0033] In the specific structure of the side connection plate assembly, such as Figure 1 , 2As shown, the side connecting plate assembly includes a third connecting plate 350, a top connecting plate 370, and a fourth connecting plate 360 ​​connected in sequence. One end of the third connecting plate 350 and the fourth connecting plate 360 ​​is fixedly connected to the support base plate 310, and the top connecting plate 370 is disposed opposite to the support base plate 310. The cross-sectional dimensions of the first connecting plate 320, the second connecting plate 330, the third connecting plate 350, and the fourth connecting plate 360 ​​gradually decrease outward from the support base plate along their respective extension directions.

[0034] In this embodiment, a third connecting plate 350 and a fourth connecting plate 360 ​​are respectively connected between the side ends of the first connecting plate 320 and the second connecting plate 330. One end of the third connecting plate 350 is fixedly connected to the support base plate 310, and both sides of the third connecting plate 350 are fixedly connected to the first connecting plate 320 and the second connecting plate 330, respectively. Similarly, one end of the fourth connecting plate 360 ​​is fixedly connected to the support base plate 310, and both sides of the fourth connecting plate 360 ​​are fixedly connected to the first connecting plate 320 and the second connecting plate 330, respectively. This allows the third connecting plate 350 and the fourth connecting plate 360 ​​to enclose the side ends between the first connecting plate 320 and the second connecting plate 330, thereby forming a lateral support structure that provides additional stability and resistance to deformation. In addition, a top connecting plate 370 is installed on one side of the support base plate 310. The two ends of the top connecting plate 370 are fixedly connected to the third connecting plate 350 and the fourth connecting plate 360 ​​respectively, and the two sides of the top connecting plate 370 are fixedly connected to the first connecting plate 320 and the second connecting plate 330. This can further enhance the structural strength and rigidity of the entire support and effectively prevent deformation and breakage.

[0035] It should be noted that the cross-sectional lengths of the first connecting plate 320, the second connecting plate 330, the third connecting plate 350, and the fourth connecting plate 360 ​​all gradually decrease from the support base plate 310 in their respective extending directions, i.e., they are all "narrower at the top and wider at the bottom" structures. This structure helps to reduce self-weight and also increases the connection strength with the support base plate 310, further improving the stability and load-bearing capacity of the connection parts.

[0036] like Figure 3 As shown, the support base plate 310 has at least two spaced mounting components along a first direction. Each mounting component has multiple mounting holes 311 evenly spaced along a second direction. The mounting holes 311 are connected to the axle 100 via fixing pins. The first and second directions intersect. The support base plate 310 has positioning pin holes 312 between the two mounting components. The positioning pin holes 312 are used for positioning and mounting with the axle 100.

[0037] In this embodiment, the first direction is the length direction of the support base plate 310, and the second direction is the width direction of the support base plate 310. In the connection structure with the axle 100, two sets of mounting components are provided on the support base plate 310. The two mounting components are distributed along the length direction of the support base plate 310 at both ends of the support base plate 310, and the first connecting plate 320 and the second connecting plate 330 are fixed between the two mounting components. Each mounting component includes a section along the width of the support base plate 310. The mounting holes 311 are evenly spaced in the direction. During installation, a fixing pin passes through the mounting holes 311 and the axle 100 to fix the support base plate 310 to the axle 100. The fixing pin can be a bolt to ensure the firmness and stability of the connection. In addition, the support base plate 310 adopts a thickened design to enhance its load-bearing capacity and durability. The support base plate 310 is provided with multiple mounting holes 311 to distribute the stress points and improve the strength and deformation resistance of the connection between the support base plate 310 and the axle 100.

[0038] In addition, a positioning pin hole 312 is provided in the middle of one end of the support base plate 310 near the axle 100. By cooperating with the positioning pin on the axle 100 through the positioning pin hole 312, the relative position of the support and the axle 100 can be quickly determined, improving the connection efficiency. At the same time, the cooperation between the positioning pin and the positioning pin hole 312 can provide additional support and fixation, preventing relative displacement and loosening of the components during operation, and enhancing the stability and reliability of the overall structure.

[0039] Example 2

[0040] Please see Figure 4 The present invention also provides a suspension structure, including an axle 100, a lateral push rod 200, and a rear suspension lateral push support as described in any of the above. The support base plate 310 is fixedly connected to the axle 100. The lateral push rod 200 has a first ball pin and a second ball pin at both ends along its own axial direction. The first ball pin is connected to the axle 100, and the second ball pin is connected to the lateral push mounting seat 340.

[0041] In this embodiment, the support base plate 310 is bolted to the axle 100. The lateral thrust 200 has a first ball pin and a second ball pin at both ends along its axial direction. The first ball pin is connected to the axle 100, and the second ball pin is connected to the lateral thrust mounting seat 340 on the first connecting plate 320, allowing the lateral thrust 200 to be mounted on the support. This mounting method of the support, axle 100, and lateral thrust 200 enables them to better withstand lateral thrust and the overall load of the vehicle, improving the overall load-bearing capacity of the axle 100 and the suspension system. The connection between the lateral thrust 200 and the support ensures that the lateral thrust 200 can effectively transmit and disperse the impact and vibration of the vehicle during driving, reducing stress concentration in the suspension system.
