A frame assembly suitable for an amphibious vehicle

Abstract

The invention discloses a frame assembly suitable for an amphibious vehicle. Sealing plate, the steering system mounting seat, the front axle main reducer mounting seat, the engine front suspension support beam, the land transfer case support beam, the front cross beam, Rear beam, middle axle main reducer mounting seat, rear axle angle transmission box mounting seat; all parts of the frame assembly are welded with titanium alloy material, light weight, high strength, corrosion resistance; and good sealing, The streamlined shape of the car body is ensured, and the passability of the whole car in water is improved; in addition, various system installation interfaces are reserved on the frame assembly, which is a universal frame with reasonable and novel structural design. It can be converted between tire and track drive, making the vehicle have good passability in complex environments such as water, land and swamps.

Description

【Technical field】 [0001] The invention relates to the technical field of amphibious vehicles, in particular to a frame assembly suitable for an amphibious vehicle. 【Background technique】 [0002] Amphibious vehicles mainly use wheeled or crawler transmission as the driving form under land, wetland or water conditions, and need to take into account the high-speed travel on land and soft road conditions such as tidal flats, wetlands and swamps. The amphibious vehicle is a key component of the vehicle chassis and the vehicle. The amphibious vehicle connects and fixes the vehicle, body, hull, crawler system, suspension system, transmission system and other structures through the frame assembly to ensure the normal use of the amphibious vehicle. [0003] The frame structure of the existing amphibious vehicles has the following defects: most of the traditional amphibious vehicles are modified on the basis of the existing vehicles, and the frame structure is open, and the suspensio...

Problems solved by technology

[0003] The frame structure of the existing amphibious vehicles has the following defects: most of the traditional amphibious vehicles are refitted on the basis of existing vehicles, and the frame structure is open, and the suspension system, steering system, To avoid problems with tires and other systems, connect them to the hull and perform sealing and sealing treatment, the space is limited, it is difficult to meet the needs of structural adjustment and vehicle layout, and the versatility and adaptability are poor; the frame of traditional amphibious vehicles adopts high-strength As its main material, steel plate has high density and mass, and the draft of the car body is relatively deep, which increases the resistance of the vehicle when driving and sailing, and reduces the load-carrying capacity and fuel economy of the vehicle; moreover, its corrosion resistance is poor in the marine environment. Relying on the coating process for anti-corrosion and anti-corrosion treatment, the coating is complicated, and at the same time increases the cost of later maintenance
