Hydraulic-drive amphibious boat

Abstract

The invention relates to a hydraulic-drive amphibious boat. According to the hydraulic-drive amphibious boat, traveling in the double environments including the waterway environment and the landway environment is achieved. The hydraulic-drive amphibious boat comprises a hull, wherein an outboard engine is installed on the tail portion of the hull and is connected with a control circuit; a land traveling wheel system is installed at the bottom of the hull, each wheel in the land traveling wheel system is provided with a hydraulic motor, and the hydraulic motors are connected with a hydraulic control device; a hydraulic steering device is further arranged on the front wheels, and is also connected with the hydraulic control device; each wheel in the land traveling wheel system is provided with a hydraulic lifting device, and the hydraulic lifting devices are connected with the hydraulic control device; the hydraulic control device is connected with a water and land mode switching box, and the water and land mode switching box comprises a first output shaft and a second output shaft; the first output shaft is connected with the hydraulic control device through a rotary valve; the second output shaft is connected with the outboard engine through a transmission device; a switching device is connected with a switching box lever; a steering wheel device is connected with an input shaft of the switching device; the hydraulic control device is provided with a plurality of motor pumps which are connected with the control circuit; a power source provides needed electric 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
