Abstract

The invention relates to a hydraulically driven amphibious ship to realize dual-environment driving on water and land. It includes: the hull, the outboard motor is installed at the tail to connect with the control circuit; the land travel gear train is installed at the lower part of the hull, and each wheel in the land travel gear train has its own hydraulic motor and is connected to the hydraulic control device; the front wheels are also equipped with Hydraulic steering device, the hydraulic steering device is also connected with the hydraulic control device; each wheel of the land travel wheel system is equipped with a hydraulic lifting device, and is connected with the hydraulic control device; the hydraulic control device is connected with the land and water mode conversion box, and the land and water mode conversion box Including the first output shaft and the second output shaft; the first output shaft is connected with the hydraulic control device through the rotary valve; the second output shaft is connected with the outboard engine through the transmission device; the switching device is connected with the conversion box lever; the steering wheel device is connected with the switching device The input shaft is connected; the hydraulic control device is provided with multiple motor pumps, and each motor pump is connected to the control circuit; the power supply provides the required power.

Description

Technical field: [0001] The invention relates to a hydraulically driven amphibious ship. Background technique: [0002] Speedboat is a common means of water transportation, but it needs a trailer to transfer on land. Especially in the places where there are many shallows, how to transfer the motorboat to the deep water becomes a difficult problem. [0003] The current land drive of amphibious ships is mainly driven by hub motors, which have strict sealing requirements, are not safe, and have low drive torque. Many amphibious boats have separate land and water drive modes. When on land, the steering wheel is used to control the direction, while in the water, you need to sit at the stern and manually control the outboard motor, which is time-consuming and laborious, and the steering of the outboard motor cannot be precisely controlled.

AI Technical Summary

Problems solved by technology

[0003] The current land drive of amphibious ships is mainly driven by hub motors, which have strict sealing requirements, are not safe, and have low drive torque.

Many amphibious boats are driven separately on land and in water. When on land, the steering wheel is used to control the direction, while in the water, you need to sit at the stern and manually control the outboard motor, which is time-consuming and laborious, and the steering of the outboard motor Can't get precise control

[0004] The wheels of existing amphibious electric boats cannot be retracted upwards, and it is easy to catch other things in the water, get entangled in the car, and affect the driving performance of the boat

[0005] Each wheel of the amphibious boat developed by sealegs is driven by a hydraulic motor. This driving method undoubtedly increases the weight of the hull and makes the price very expensive

This ship uses a gasoline engine to power the hydraulic motor. Due to the limited fuel carried each time, the mileage of the ship is limited. If the fuel tank is increased, the weight of the ship will undoubtedly increase, and this method will cause environmental pollution due to the use of a large amount of fuel.

Not only that, this kind of ship uses a mechanical mechanism to steer. On muddy and soft beaches, this kind of steering increases human fatigue, and the ship has been immersed in seawater for many years, it is difficult to ensure the stability of its mechanical steering mechanism

[0006] The existing folding amphibious boats with wheels are rear-wheel hydraulically driven, and there is no description of the conversion between water drive and road drive, and if the rear wheels are driven by dual hydraulic motors, a differential is required, which increases the cost and increases Reduced ship failure rate, reduced availability
