[0020] Compared with the prior art, the advantages of this application are:
[0021] The counterweight system of this application is used for vehicle chassis testing. The counterweight system includes a counterweight part, a counterweight bracket, and a support base. The counterweight bracket is used to support the counterweight part. The counterweight bracket includes two first beams and two second beams. The two first beams are arranged at intervals, and the two second beams are arranged at intervals between the two first beams. The first beams and the second beams are fixedly connected and enclose a first space. The first beams and / or the second beams can be configured with different length specifications.

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.
[0030] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a counterweight system provided in an embodiment of this application. The counterweight system for vehicle chassis testing includes a counterweight unit, a counterweight bracket 100, and a support base 200, wherein:
[0031] The counterweight unit simulates the mass distribution of vehicle superstructure equipment to meet the load requirements during chassis testing. Different specifications of counterweights can be selected according to test needs, and modular design allows for rapid replacement and adjustment. The shape and material of the counterweights are optimized to ensure their stability and reliability during testing. Furthermore, the counterweight unit can be equipped with sensors to monitor load distribution and center of gravity position in real time, supporting accurate data acquisition.
[0032] like Figure 1 As shown, the counterweight support 100 is used to support the counterweight part. The counterweight support 100 includes two first beams 101 and two second beams 102. The two first beams 101 are arranged at intervals, and the two second beams 102 are arranged at intervals between the two first beams 101. The first beams 101 and the second beams 102 are fixedly connected and enclose a first space. The first beams 101 and / or the second beams 102 can be configured with different length specifications.
[0033] like Figure 1 As shown, the counterweight support 100 is a key structure supporting the counterweight, formed by two first beams 101 and two second beams 102. The two first beams 101 are arranged at intervals to form the main support frame of the system; the two second beams 102 are arranged at intervals between the two first beams 101, and together they enclose a stable first space through fixed connections with the first beams 101. This not only improves the load-bearing capacity of the support but also provides sufficient space for the installation and adjustment of the counterweight.
[0034] like Figure 1As shown, the lengths of the first beam 101 and / or the second beam 102 can be configured according to actual needs to adapt to vehicle chassis of different sizes and shapes. This adjustability allows the counterweight bracket 100 to be widely used in various vehicle models, significantly improving the system's versatility and flexibility. Furthermore, the counterweight bracket 100 uses high-strength bolt connections instead of traditional welding, which not only facilitates installation and disassembly but also allows for rapid adjustment of the bracket's size and shape according to testing requirements, further enhancing the system's scalability and maintenance convenience.
[0035] like Figure 1 , Figure 2 As shown, Figure 2 This is a schematic diagram of the support base 200 provided in an embodiment of this application. The support base 200 is detachably connected to the bottom of the counterweight bracket 100 and is used for fixing the vehicle chassis. The support base 200 connects the counterweight bracket 100 and the vehicle chassis, and is firmly fixed to the vehicle chassis while providing sufficient support force to ensure the stability of the counterweight system. The detachability of the support base 200 makes it more convenient to install and disassemble, greatly reducing assembly difficulty and time costs.
[0036] The counterweight system can also be equipped with a wireless communication module to transmit test data to the control center in real time, enabling remote monitoring and data analysis. This improves the efficiency and accuracy of the test.
[0037] The counterweight system is suitable for various vehicle chassis testing scenarios, including but not limited to special off-road vehicles, heavy trucks, and engineering vehicles. The counterweight system can be quickly adapted to different vehicle chassis models, significantly improving testing efficiency and versatility, reducing assembly difficulty and maintenance costs, and shortening the development cycle.
[0038] In an optional embodiment, the counterweight system of this application is used for vehicle chassis testing. The working principle of the counterweight system is as follows: the counterweight system includes a counterweight part, a counterweight bracket 100, and a support base 200. The counterweight bracket 100 is used to support the counterweight part. The counterweight bracket 100 includes two first beams 101 and two second beams 102. The two first beams 101 are arranged at intervals, and the two second beams 102 are arranged at intervals between the two first beams 101. The first beams 101 and the second beams 102 are fixedly connected and enclose a first space. The first beams 101 and / or the second beams 102 can be configured with different length specifications. The support base 200 is detachably connected to the bottom of the counterweight bracket 100 and is used to fix the vehicle chassis.
[0039] The first beam 101 and / or the second beam 102 can be configured with different lengths, allowing the counterweight bracket 100 to be flexibly adjusted in size to adapt to different vehicle chassis models, significantly improving its versatility. The support base 200 is fixed to the bottom of the counterweight bracket 100 using a detachable connection method and is used to fix the vehicle chassis. This facilitates installation and disassembly and allows for quick adaptation to the structural characteristics of different chassis, further enhancing the versatility of the counterweight system.
[0040] The flexible connection between the counterweight unit, counterweight bracket 100, and support base 200 allows for quick replacement and adjustment as needed, significantly reducing maintenance difficulty and costs. It also reduces reliance on customized components, enabling standardized production and universal management of parts. This not only lowers production costs but also eliminates the need to redesign and manufacture dedicated counterweight devices for each vehicle model, thereby greatly shortening the R&D cycle, improving R&D efficiency, and reducing R&D costs.
[0041] Two first beams 101 and two second beams 102 enclose a first space, providing stable support for the counterweight and ensuring the stability of the counterweight system during the test, thereby improving the accuracy and reliability of the test. By adjusting the length of the beams and the position of the support 200, the center of gravity and mass distribution of different superstructures can be accurately simulated, making the test results closer to actual working conditions and providing more accurate data support for research and development.
[0042] like Figure 1 , Figure 2 As shown, in an optional embodiment, the two first beams 101 are arranged parallel to each other, the two second beams 102 are arranged parallel to each other, and the first beams 101 and the second beams 102 are arranged perpendicular to each other.
[0043] In this embodiment, two first beams 101 are arranged parallel to each other, and two second beams 102 are also arranged parallel to each other, with the first beams 101 and second beams 102 arranged perpendicularly to each other, forming a stable rectangular frame structure. This not only improves the load-bearing capacity and stability of the counterweight support 100, but also facilitates the installation and disassembly of the counterweight blocks. The dimensions of the entire counterweight support 100 can be adjusted according to the specific requirements of the vehicle chassis. The first beams 101 and second beams 102 can be configured as I-beams or channel steel, respectively, to increase structural strength and load-bearing reliability.
[0044] The counterweight bracket 100 can be quickly adapted to different vehicle chassis models, reducing the need for customized designs and thus lowering R&D and production costs. Furthermore, the bracket's size can be adjusted by increasing or decreasing the number of beams to meet different load and center-of-gravity distribution requirements.
[0045] like Figure 1 , Figure 2 As shown, in an optional embodiment, a plurality of reinforcing parts 301 are provided at intervals between the two first beams 101.
[0046] In this embodiment, multiple reinforcing sections 301 are spaced apart between the two first beams 101 to improve the structural strength of the counterweight support 100. The reinforcing sections 301 can be made of high-strength steel and can be triangular or rectangular in shape. For example, placing a reinforcing section 301 every 0.5 meters can effectively enhance the torsional resistance and bending stiffness of the counterweight support 100, making it particularly suitable for heavy vehicle chassis tests that require bearing large loads.
[0047] The reinforcement unit 301 not only improves overall strength but also reduces material usage through optimized structural design, thereby lowering overall weight and cost. Furthermore, the reinforcement unit 301's modular design allows for interchangeability between different supports, further enhancing the system's scalability and economy.
[0048] like Figure 1 , Figure 2 As shown, in an optional embodiment, a plurality of support portions 302 are provided between the two first beams 101, and the height of the top surface of the support portion 302 is the same as the height of the top surface of the first beam 101.
[0049] The support portion 302 is used to directly support the counterweight portion. The surface of the support portion 302 can be designed with an anti-slip texture to prevent the counterweight from sliding during the test. For example, the support portions 302 can be fixed between the first beams 101 by welding or bolting. The number and spacing of the support portions 302 can be adjusted according to the size and weight of the counterweight, thereby improving the stability and reliability of the system.
[0050] like Figure 1 , Figure 2 As shown, in an optional embodiment, the counterweight support 100 is fixedly connected with spaced-apart retaining beams 303, one end of which is higher than the counterweight support 100.
[0051] The function of the retaining beam 303 is to prevent the counterweight from shifting or slipping during the test. For example, the height of the retaining beam 303 can be set to extend 10 cm beyond the top of the counterweight to ensure that the counterweight does not detach from the support. The retaining beam 303 can be made of steel or aluminum alloy with a corrosion-resistant surface treatment to improve durability. The retaining beam 303's modular design allows it to be used across different supports, further improving the system's scalability and economy.
[0052] like Figure 1 , Figure 2As shown, in an optional embodiment, a side beam 304 is fixedly connected between the stop beam 303 and the counterweight bracket 100, and the stop beam 303 includes at least two vertical baffles 305.
[0053] The vertical baffle 305 further enhances the stability of the retaining beam 303, while the side beam 304 can be fixed to the counterweight bracket 100 using high-strength bolts. The side beam 304 effectively prevents the lateral movement of the counterweight while also providing a mounting base for the retaining beam 303, thus improving the stability and safety of the system.
[0054] like Figure 1 , Figure 2 As shown, in an optional embodiment, the support base 200 is provided in multiple ways and is spaced apart from each other to support the counterweight bracket 100 in the width direction. The support base 200 includes a base plate 201 and a support leg 202 fixed under the base plate 201. The counterweight bracket 100 is fixedly connected to the base plate 201.
[0055] Each support 200 includes a base plate 201 and outriggers 202 fixed under the base plate 201. The counterweight bracket 100 can be fixed to the base plate 201 by bolts, providing stable support for the counterweight bracket 100. The number and spacing of the support 200 can be adjusted according to the structure and load distribution of the vehicle chassis to ensure the stability of the entire system.
[0056] While multiple support seats 200 support the counterweight bracket 100 at intervals, the position of the counterweight bracket 100 can also be adjusted in the width direction to achieve a more stable support effect. Through the adjustment of the support seats 200, it can be more flexibly adapted to different chassis systems.
[0057] like Figure 1 , Figure 2 As shown, in an optional embodiment, a reinforcing plate 203 is provided inside the support leg 202 and at the bottom of the base plate 201, an inclined support plate 204 is provided between the outer side of the support leg 202 and the base plate 201, and a pad 205 is provided at the bottom of the support leg 202.
[0058] The reinforcing plate 203 can be made of thick steel plate to enhance the structural strength of the outrigger 202 and the base plate 201. The tilt angle of the support plate 204 can be adjusted according to actual needs, for example, set to a 45-degree angle to improve the stability of the support base 200. The pad plate 205 can be made of rubber material to cushion vibrations during vehicle operation, protect the outrigger 202 from damage, and further improve the service life of the system.
[0059] like Figure 1 , Figure 2As shown, in an optional embodiment, the length of the base plate 201 is greater than the width of the counterweight bracket 100, and each end of the base plate 201 is provided with a mounting plate 401. One side of the mounting plate 401 is fixedly connected to the top surface of the base plate 201, and the other side is fixedly connected to the outer side wall of the counterweight bracket 100. A reinforcing rib 402 is provided in the middle of the mounting plate 401.
[0060] One side of the mounting plate 401 is fixedly connected to the top surface of the base plate 201, and the other side is fixedly connected to the outer wall of the counterweight bracket 100. A reinforcing rib 402 is provided in the middle of the mounting plate 401. By adding the mounting plate 401 and the reinforcing rib 402, the stability and load-bearing capacity of the system are further improved.
[0061] The mounting plate 401 and reinforcing rib 402 not only improve the connection strength between the base plate 201 and the counterweight bracket 100, but also reduce installation time and cost through modular design. In addition, the number and spacing of the mounting plates 401 can be adjusted to accommodate counterweight brackets 100 of different sizes.
[0062] like Figure 1 , Figure 2 As shown, in an optional embodiment, the outer wall of the counterweight support 100 is provided with a plurality of hooks 403. The hooks 403 can be used to suspend tools or auxiliary equipment, such as measuring instruments or safety ropes during testing. The spacing of the hooks 403 can be adjusted according to actual needs, and the load-bearing capacity of the hooks 403 can be designed according to test requirements, thereby improving the scalability and economy of the system.
