Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid steering apparatus for a outboard ship,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a steering apparatus for a outboard ship, and more particularly, to a hybrid steering apparatus for a outboard ship that maintains the steering force of a outboard boat based on a hydraulic power pack.

In general, it is advantageous to install an automatic pilot system in addition to a hydraulic power pack, but it is difficult to apply the method mounted on a shipboard ship in the case of a small outboard ship smaller than this. To introduce semi-hydraulic power packs and automatic steering systems on outboard vessels, it is necessary to solve interlocking and error problems by transforming them into specialized equipment.

Korean Patent Registration No. 1294960 (Prior Art 1), Korean Patent Registration No. 0429068 (Prior Art 2), etc. are known as prior art documents which can be referred to in this connection.

The prior art document 1 advances or retreats the piston by selecting the air input hose to which the air supplied from the air compressor is to be output in accordance with the operation of the directional control valve, and by moving the piston forward or backward, And the outboard motor of the additional ship is configured to be rotated by pushing or pulling it from the side. Therefore, it is expected to have a steering effect by a simple operation far away from the outboard motor without any manpower for steering.

The prior art document 2 is a steering apparatus for a marine vessel using an electric motor and a steering handle, which comprises an electronic control unit including a function selection switch unit; A handle connecting spool connected to the steering handle; (Omitted) a cylinder operated through the oil inside the high pressure oil hose; A tiller for converting the linear motion of the cylinder into a rotary motion, and a rudder connected to the tiller. Therefore, we expect the effect of selecting an efficient steering system depending on the situation such as remote control, compass steering control, and flow steering control.

However, according to the above-mentioned prior art, since the motor always operates for driving the air compressor or the electric motor, the lifetime of the motor is lowered, and at the same time, the failure of the motor may cause the steering function of the outboard motor vessel to be lost.

1. Korean Registered Patent No. 1294960 entitled "Steering Device of Ship" (Open date: March 30, 2012) 2. Korean Patent Registration No. 0429068 entitled " Automatic Steering and Automatic Control Device for Ship "(Published on July 25, 2001).

In order to solve the above-mentioned problems, it is an object of the present invention to provide a hybrid steering system that is based on a hydraulic power pack connected in parallel to a ship equipped with a outboard motor, Device.

In order to achieve the above object, the present invention provides an apparatus for steering a ship equipped with a outboard motor, comprising: an operating cylinder connected to switch the direction of the outboard motor; A manual operating portion connected to one side rod of the operating cylinder and operating a manual steering force through a steering handle; And a hydraulic operating part connected to the other rod of the operating cylinder and operating a hydraulic pressure steering force through a steering knob.

In a detailed configuration of the present invention, the manual operating portion includes a steering shaft connected via a worm gear, and a rack pinion interposed between the rod and the steering shaft.

As a detailed configuration of the present invention, the manual operating portion is characterized by having a one-way clutch for one-way transmission between the operating cylinder and the steering handle.

In a detailed configuration of the present invention, the hydraulic operating portion is connected to the operating cylinder in a parallel circuit together with a steering knob disposed at a plurality of positions.

As a modification of the present invention, the hydraulic control unit is connected to the control means of the microcomputer circuit so as to realize the wireless and remote steering, and the control means performs the steering with the set algorithm by using the signals of the steering angle sensor and the wireless module .

As described above, according to the present invention, there is an effect that the life of the motor is increased and the steering force of the outboard motor ship is stably maintained by connecting the manual handle to the hydraulic power pack connected in parallel circuit in the ship equipped with the outboard motor.

Fig. 1 is a schematic diagram showing the whole of the steering apparatus according to the present invention
2 is a schematic diagram showing a manual steering unit of the steering apparatus according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes an apparatus for performing steering of a ship equipped with the outboard motor (10). Normally, the power pack is based on a hydraulic device and excludes manual steering force, but a semi-hydraulic power pack is advantageous for small and medium sized ships. However, the actual application of the semi-hydraulic power pack is not so active at present, and most of the power packs used for automobiles are used. In the case of anti-hydraulic type applied ships, it is not possible to apply automatic steering. Therefore, the manpower that can be operated must always stay in the steering room.

According to the present invention, there is provided an operating cylinder (12) connected to switch the direction of the outboard motor (10). The operating cylinder 12 is a hydraulic device for switching the direction of the outboard motor 10, and a rod 14 connected to an inner piston is formed on one side and the other side. Although the double acting type is suitable for the operating cylinder 12, it is not necessarily limited thereto.

In addition, according to the present invention, the manual operation portion 20, which applies manual steering force through the steering handle 22, is connected to one rod 14 of the actuating cylinder 12. The manual operating portion 20 rotates the steering handle 22 with a force to cause the movement of the operating cylinder 12 and the rod 14. [ Since the manual operation unit 20 is independent of the motor, it does not consume electricity and is effective in an emergency in which the power supply is insufficient.

As a detailed configuration of the present invention, the manual operating portion 20 includes a steering shaft 24 connected via a worm gear, and a rack pinion 28 interposed between the rod 14 and the steering shaft 24 . The steering shaft 24 can be variously configured according to the position of the outboard motor 10 and the steering handle 22. In any case, when the worm gear is interposed, a deceleration function is performed, so that a large torque can be generated with a small force. 2, when a rack is formed on one surface of the rod 14 and the pinion meshed with the pinion is connected to the steering shaft 24, the manual steering force of the steering handle 22 is actuated via the steering shaft 24 and the rack pinion 28 And is transmitted to the cylinder 12.

The manual operating portion 20 is characterized by having a one-way clutch 26 for unidirectional transmission between the operating cylinder 12 and the steering handle 22 as a detailed configuration of the present invention. A state in which the one-way clutch 26 is provided between the pinion of the rack pinion 28 and the steering shaft 24 in Fig. 2 is illustrated. The one-way clutch 26 transmits the manual steering force via the steering handle 22 to the operating cylinder 12 but conversely the hydraulic steering force by the operating cylinder 12 is transmitted to the steering shaft 24 and the steering handle 22, . This alleviates the burden on the motor 36 of the hydraulic control unit 30, which will be described later, to extend durability and service life. Of course, it is also possible to add a manual steering force while the hydraulic steering force acts.

In addition, according to the present invention, the hydraulic operating portion 30, which acts on the steering knob 32 through the steering knob 32, is connected to the other rod 14 of the operating cylinder 12. The hydraulic control unit 30 is based on a pump 34 and a motor 36 for transferring operating oil and allows the hydraulic oil to be delivered to the operating cylinder 12 through the hydraulic pipe 38. [ The steering knob 32 performs a function of switching the flow path of the operating oil to cause one side or the other side of the operating cylinder 12 with respect to the rod 14.

As a detailed configuration of the present invention, the hydraulic control section 30 is connected to the operating cylinder 12 in a parallel circuit together with a steering knob 32 disposed at a plurality of positions. One hydraulic control unit 30 and the other hydraulic control unit 30 are connected via a valve on the hydraulic pipe 38 and connected to the operating cylinder 12. 1 schematically illustrates a connection state between the steering knob 32 and the hydraulic pipe 38, the hydraulic control unit 30 is a redundancy system based on a parallel circuit. Accordingly, when a problem occurs in the motor 36 in any of the hydraulic control portions 30, the other hydraulic control portion 30 can be operated to maintain a stable steering force.

The life of the motor is limited (up to about 2 years) because the durability of the motor is drastically reduced in order to operate the hydraulic pressure using the motor continuously while the main engine is operating in the ship to which the conventional power pack is applied. On the other hand, according to the outboard motor boat to which the present invention is applied, the manual handle and the power pack can be selected and used in a hybrid manner, and the burden on the motor is reduced by applying the power pack of the parallel circuit. Times more.

On the other hand, the pumps 34 and 36 in the hydraulic control unit 30 on one side and the other side may be configured to intermittently transmit power. In this case, the pump 34 and the motor 36 are separated from each other by the unused hydraulic control unit 30, thereby preventing wear.

The hydraulic control unit 30 is connected to the control means 40 of the microcomputer circuit so as to realize wireless and remote steering and the control means 40 controls the steering angle sensor 42 and the wireless module 44 And the steering angle is set to a predetermined value. The control means 40 is based on an ECU 46 equipped with a microprocessor, a memory and an input / output interface. The steering angle sensor 42 can use an encoder and generates a steering angle signal in the outboard motor 10 or the rudder. The wireless module 44 includes hardware and embedded software for performing a remote steering function in addition to a wireless steering function such as a GPS plotter and an E-compass. The ECU 46 mounts a main program, a communication protocol, and the like for executing the algorithm set on the memory.

The ECU 46 operates the motor 36 and the pump 34 of the hydraulic control unit 30 of one side to receive signals of the radio steering or remote steering signals and operates the hydraulic pipe 38 (Not shown) in order to change the operating oil path of the outboard motor 10, so that the operation of the operating cylinder 12 causes the changeover of the outboard motor 10.

1, the ECU 46 of the control means 40 is connected to the hydraulic control unit 30 on one side. In this case, the hydraulic control unit 30 to which the ECU 46 is connected may be classified as a master unit, and the remaining hydraulic control unit 30 may be classified as an auxiliary unit.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
