In a surface mode of operation: the transmission ratio in the transmission assembly 220 is in a 1:1 position through manual operation, and the six wheel assemblies 270 are lifted upwards by 300-500 mm through the hydraulic oil cylinder 136 and the hydraulic shock absorber assembly 137 respectively; the hydraulic clutch in the power distribution box 230 enters a 'supercharging state', the engine torque is only transmitted to (two) rear output shafts A233 in the power distribution box 230, and the (two) water surface propellers 280 are directly driven to run at a high speed through (two) jet pump transmission shafts 254; the minimum turning radius and the water surface pivot turning of the vehicle when running on the water surface can be conveniently realized by directly controlling the steering nozzle at the tail part of the water surface propeller 280 through the steering wheel 514 and the steering transfer case 530.

The working principle and the process of realizing the 'wheel deflection lifting' by the double-fork-arm structure 130A are as follows: when the vehicle enters a water surface running mode, the wheel lifting control device 550 is manually operated to enable the hydraulic oil cylinder 136 to extend upwards, the shock absorber assembly 131 and the lower swing arm 133 are pulled through the rotating arm 135, and the wheel hub connecting plate assembly 271 and the wheel assembly 270 thereof which are sequentially connected with the upper swing arm 132 and the lower swing arm 133 rotate upwards by taking a pin shaft on the connecting seat 134 as a center, so that the hub connecting plate assembly 271 and the wheel assembly 270 thereof are rapidly deflected upwards to lift by more than 500 mm (at the moment, the hydraulic cylinder enters a self-locking state); when the vehicle returns to the "land running" mode, the wheel lifting control device 550 and the hydraulic cylinder 136 are manually operated to release self-locking and contract downwards to the initial setting position, so as to drive the shock absorber assembly 131 and the lower swing arm 133 to rotate reversely together, so that the hub connecting plate assembly 271 and the wheel assembly 270 thereof descend orderly until the initial setting position is reached (at this time, the hydraulic cylinder enters the self-locking state again).

The working principle and the process of the rocker arm structure 130B for realizing 'wheel lifting' in the invention are as follows: when the vehicle enters a water surface running mode, the wheel lifting control device 550 is manually operated to enable the hydraulic cylinder in the hydraulic shock absorber assembly 137 to contract upwards and pull the rocker arm 138 to deflect upwards by taking a pin shaft in the mounting seat at the upper end of the rocker arm 138 as a center, so that the hub connecting plate assembly 271 and the wheel assembly 270 which are fixedly arranged at the lower end of the rocker arm 138 are rapidly lifted upwards by more than 300 millimeters (at the moment, the hydraulic cylinder enters a self-locking state), when the vehicle returns to a land running mode, the wheel lifting control device 550 and the hydraulic cylinder are manually operated to release self-locking, the hydraulic cylinder in the hydraulic shock absorber assembly 137 extends downwards to an initial setting position and drives the rocker arm 138 to deflect reversely, so that the hub connecting plate assembly 271 and the wheel assembly 270 thereof descend orderly until the hub connecting plate assembly 271 and the wheel assembly 270 return to the initial setting position (at the moment, the hydraulic cylinder enters the self-locking state again).

In the "water surface running" mode, the wheels are lifted off the water surface by "deflecting lifting" or "directly lifting" by manually operating the wheel lifting control device 550, which has significant effects on significantly reducing water resistance, improving the water surface speed per hour of the amphibious vehicle, saving energy and reducing consumption.

The buoyancy required by the water surface operation of the invention is provided by the front buoyancy tank 310, the rear buoyancy tank combination 330 and the (two) middle buoyancy tanks 320 at the bottom of the vehicle body; the (two) movable buoys 340 have the significant effect and obvious effect of greatly improving the displacement (namely the water surface rescue bearing capacity) and the water surface operation stability of the amphibious vehicle.

The driving operation rule of the invention is as follows: the land-based operation device 510 operates in exactly the same manner as an off-road vehicle; when the water surface runs, only the function change-over switch in the wheel lifting control device 550 needs to be pressed, the six wheel assemblies 270 automatically deflect upwards and lift by 300 and 500 mm, and the two water surface propellers 280 start to run; all electronic instruments (including observation equipment such as military vehicle-mounted radar, sextant and the like) on the vehicle are sealed and independently stored in the instrument integration device 540, so that the problem that a vehicle control system is possibly invalid when the vehicle runs on the water surface can be avoided to the maximum extent; the correct direction of the vehicle running on the water surface can be ensured by the guidance of the radio signals sent by the vehicle-mounted electronic equipment and the base navigation station.

Due to the adoption of the technical scheme, the invention perfectly realizes the aim of the invention, comprehensively and systematically shows the key common technologies of four aspects of high-efficiency power transmission, light whole vehicle weight, resistance and speed reduction on the water surface, global safe operation and the like which are mastered at present, and has the following outstanding advantages and beneficial effects compared with similar products.

As can be seen from fig. 1, 2 and 9, in order to ensure the reliable impact strength of the vehicle, to ensure the light weight of the whole vehicle, and to fundamentally solve the problem of improving the seawater corrosion resistance of the vehicle when used at sea, the frame assembly 110, the roll cage assembly 120 and the lifting suspension mechanism 130 are made of titanium alloy (TC 4); particularly, the hull shell 410, the body covering component 440 and the interior component 450 are made of carbon fiber or aluminum magnesium alloy (5083).

As further shown in fig. 1 and 2, in order to maintain the interior space of the vehicle to the maximum and ensure sufficient strength of the vehicle, a frame assembly 110 originally invented by the applicant is specially selected; the frame assembly 110 is formed by bending and welding a plurality of components through a special process, and has higher safety protection performance after being analyzed by a finite element system; after the roll cage assembly 120 is orderly welded on the upper part of the frame assembly 110, the roll-over prevention safety performance of the invention is further improved.

As also shown in fig. 1 and 7, a buoyancy system module 300, originally invented by the applicant, is specially provided to ensure absolute safety of the vehicle when operating on water. The system module comprises a front buoyancy tank 310, two middle buoyancy tanks 320, a rear buoyancy tank combination 330 and the like, and is convenient to assemble and simple to maintain. The front buoyancy tank 310, the two middle buoyancy tanks 320 and the rear buoyancy tank assembly 330 are respectively sequentially processed and manufactured into hollow shells by carbon fiber materials according to the space shape and size of the bottom of the vehicle body, and then are foamed and filled by EPP polypropylene; the front buoyancy tank 310 is sequentially and fixedly arranged at a preset position below the front part of the frame assembly 110 through a plurality of fastening bolts; the two middle buoyancy tanks 320 are respectively and fixedly arranged at preset positions below the left side and the right side of the middle part of the frame assembly 110 in order through a plurality of fastening bolts; the rear buoyancy tank assembly 330 is sequentially and fixedly arranged at a preset position below the rear part of the frame assembly 110 through a plurality of fastening bolts; because the displacement produced by the buoyancy system module 300 is much greater than the sum of the dead weight and the rated load of the vehicle, the vehicle can always suspend on the water surface and never sink.

As shown in fig. 1 and 8, in order to further increase the carrying capacity of the water surface rescue and the stability of the water surface operation, two movable buoys 340 are specially arranged.

As can be seen from fig. 1, 8 and 9, in order to further reduce the water resistance of the vehicle when the vehicle runs in water and continuously generate water lift power, and protect the front buoyancy tank 310, the two middle buoyancy tanks 320 and the rear buoyancy tank assembly 330 from scratch damage, the hull shell 410 which is originally created by the applicant and has the functions of wave suppression and wave elimination and high-slip performance is specially arranged; a plurality of keels are orderly arranged in the hull shell 410, and the hull shell 410 can be orderly and fixedly arranged at a preset position below the frame assembly 110 through a plurality of fastening bolts. The unique gliding bottom surface of the hull shell 410 can make the vehicle more slippery and faster when running on the water.

As also shown in fig. 1 and 3, in order to better satisfy the self-rescue of the vehicle in special occasions, an electric winch 299 is specially arranged; two electric winches 299 are respectively and sequentially fixed at preset positions at the front part and the rear part of the frame assembly 110.

As shown in fig. 1 and 3, in order to better meet the use requirements of the vehicle for amphibious high-speed running and amphibious high-efficiency maneuvering, a power transmission system which is characterized by a power distribution box 230 and has unique characteristics is specially arranged, and the system has three functions of meeting the requirements of independent work of a drive axle, independent work of a propulsion device and simultaneous work of the drive axle and the propulsion device.
