Description

Technical Field

[0001] This utility model belongs to the field of automotive chassis front-end structure technology, and particularly relates to a highly integrated engineering vehicle front connecting beam and a vehicle having the same. Background Technology

[0002] The front connecting beam is a crucial component of the engineering vehicle's frame structure. Installed at the front end of the vehicle's longitudinal beams, it primarily integrates the mounting surfaces of various systems in the front suspension section of the frame, directly providing mounting interfaces, reducing the number of mounting supports for each system, and thus integrating components and optimizing part complexity. As the front-end support structure of the frame, the front connecting beam plays a vital role in connecting various front-end components of the vehicle, including the steering system, suspension system, cooling system, and collision protection system.

[0003] Currently, with increasingly fierce competition in the construction vehicle market, medium and heavy-duty construction vehicle products urgently need to be updated and iterated to meet customers' ever-increasing performance demands. Existing construction vehicle front beams typically use cast steel or simple stamped parts. These front beams use a large amount of material, resulting in heavy weight, and have only a few mounting points, limiting the number of components that can be installed. They often require the use of other mounting structures to install additional parts. For different types of construction vehicles, due to varying space requirements, new front beam structures need to be designed to meet the layout space requirements.

[0004] The existing front-joint beams for engineering vehicles have the following technical problems:

[0005] First, the integration level is not high enough, requiring the use of multiple dedicated brackets to install various system components, which increases the number and complexity of the vehicle's components.

[0006] Second, the complex structure requires multiple intermediate connectors, which increases energy loss during load transfer.

[0007] Third, the existing front beams are heavy due to design and material reasons, which does not conform to the trend of lightweight automotive development. Furthermore, they lack torsional resistance when the vehicle is subjected to frontal impacts or drives on uneven roads, affecting the vehicle's driving stability. Utility Model Content

Both the left and right front connecting beams are integrally cast structures, and each of the left and right front connecting beams has multiple mounting parts for connecting the vehicle frame and vehicle components.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The high-integration front beam design for engineering vehicles provided by this utility model effectively solves the technical problems of insufficient integration and complex connection methods of existing front beams for engineering vehicles. Through the design of an integrally molded casting structure and a multi-functional mounting part, it achieves higher space utilization and more direct load transfer, meeting the needs of iterative engineering vehicle products for lightweighting and high integration.

[0025] This invention solves the problems of complex structures and numerous parts in traditional front connecting beams through an integrated casting structure design. The left and right front connecting beams are manufactured using an integrated casting process, reducing the use of intermediate connecting parts and making the connection between the front connecting beam and the longitudinal beam more direct and robust, thus improving the overall structural stability and strength. Furthermore, by setting 14 mounting parts on the left and right front connecting beams, the invention addresses the issue of limited mounting functionality in existing front connecting beams. These mounting parts are used to connect various components such as the front suspension mount, heat dissipation pad, front protection, radiator support rod, leaf spring hanger, reinforcing crossbeam, and steering gear bracket, significantly improving the integration and space utilization of the front connecting beam.

[0026] This invention also addresses the issue of insufficient strength in the front-end structure of the vehicle frame through the design of a reinforced crossbeam. The reinforced crossbeam is connected and fixed via dedicated holes on the left and right front connecting beams, forming a stable front-end frame structure that enhances the vehicle's torsional resistance and structural stability. Furthermore, the coordinated design of the front reinforced crossbeam and the left and right front traction supports solves the problem of insufficient front-end collision protection. The front reinforced crossbeam is fixed to the left and right front connecting beams via the left and right front traction supports, providing collision protection and improving the safety of the vehicle's front end. Finally, by fixing the cooling module assembly to the front connecting beams via left and right heat dissipation pads, the problem of complex cooling system layout is solved. This integrated design simplifies the installation of the cooling system, improves heat dissipation efficiency, and enhances maintenance convenience.

[0027] Furthermore, the use of pin-shaft connections to fix the leaf spring hangers solves the problem of excessive rigidity in traditional connection methods. The pin-shaft connection method allows for a certain amount of flexibility, reducing impact loads during vehicle operation and extending the service life of the leaf springs and front connecting beam.
