2. Traditional amphibious vehicles need to meet the high power requirements of water driving, so the engine power selected is relatively high, which is much higher than the power index of land driving. At the same time, the gearbox, transfer case, transmission shaft, half shaft, differential and even the braking system are bulky and heavy. The amphibious vehicle of the utility model can select a suitable land driving power according to the dynamic index of land driving, further reduce the weight of the transmission system, and improve the water driving speed of the amphibious vehicle.

3. At the same time, because the vehicle is driven by a motor on land, it also has the characteristics of low noise, low heat dissipation and high mobility, and can perform special combat tasks.

detailed description

In the structural layout schematic diagram shown in Figure 1, the utility model adopts the bridge motor hybrid system layout structure of the amphibious vehicle, the water drive system and the land drive system do not interfere with each other but are closely connected, and the land drive system torque transmission The path is: drive motor → reduction differential → half shaft → wheel, and the torque transmission path of the water drive system is: engine, motor → separation mechanism → reducer → propeller.

The water drive system mainly includes a battery pack 17, a motor 18, an engine 19, a separation mechanism 20, a speed reducer 21 and a propeller 22. Wherein engine 19 rear position, to shorten the distance of power transmission, simultaneously the weight of vehicle is more concentrated and vehicle rear portion is conducive to vehicle driving in water. The water spray side of the propeller 22 is located at the rear of the vehicle, the input shaft of the propeller 22 is connected to the reducer 21, and the separation mechanism 20 is arranged between the motor 18 and the reducer 21. When the separation mechanism 20 is separated, the propeller 22 does not work, and the separation mechanism 20 When combined, the engine 19 and the electric motor 18 may jointly drive the propeller 22 . The power of the water drive system mainly comes from the engine 19. When the power output needs to be increased, the battery pack 17 provides energy, and the motor 18 can supplement the power to improve the water mobility of the vehicle.

The land drive system mainly includes wheels 1, 2, 3, 4, axle shafts 5, 6, 7, 8, reduction differentials 9, 10, drive motors 11, 12, inverters 13, 14, 15, vehicle Controller 16, battery pack 17, motor 18, engine 19. The power source of the land driving system comes from the driving motors 11 and 12, and traditional vehicle transfer gears, gearboxes and other driving devices are eliminated, and the structure of the power system is simple. The battery pack 17 is arranged on the left side of the vehicle, and the drive motors 11, 12 are respectively arranged on the front and rear axles, which are connected with the reduction differential cases 9, 10 and drive the wheels 1, 2, 3, 4 by the axle shafts 5, 6, 7, 8. The vehicle controller 16 controls the inverters 13, 14, 15 according to the state of the battery pack 17 and the vehicle to ensure the normal operation of the vehicle. In the case of good road conditions, only the drive motor 11 works, and the vehicle is converted into a two-wheel drive mode, and the economy of the vehicle is improved. When the road conditions are complex and the power is insufficient, the drive motors 11 and 12 work at the same time, and the vehicle is converted into a four-wheel drive mode. , to ensure the dynamic performance of the vehicle. When the capacity of the battery pack 17 is insufficient, the engine 19 is started, and the motor 18 is used as a generator to charge the battery pack 17 to increase the cruising range of the vehicle.
