OUTBOARD MOTOR STEERING DEVICE AND METHOD FOR ITS MANUFACTURE AND USE
FIELD OF THE INVENTION
The invention relates to a steering device to be connected to a steering holder of an outboard motor. The invention also relates to a method for manufacturing and using such a steering device.
TECHNICAL BACKGROUND
Traditionally, an outboard motor is steered with a mechanical steering device to be connected to the steering holder of an outboard motor. In these solutions, the steering device has been connected to the steering unit itself, such as to a helm, by means of a mechanical wire. The system takes up a lot of space and it contains many parts. The mechanical steering device comprises in addition to wires also e.g. guide rollers to which a rather great mechanical stress is directed. A mechanical steering device is also relatively expensive to install and requires adjustment and recurrent maintenance. Also hydraulic steering devices are known, the problems of which are mainly similar to those of the mechanical steering devices.
GENERAL DESCRIPTION OF THE INVENTION
The objective of this invention is to develop a steering device the installation of which is particularly simple.
In order to achieve this objective, the invention is characterized by what is presented in the independent claims. In other claims, some preferred embodiments of the invention have been presented. A steering device according to the invention is used for steering an outboard motor. The invention advantageously relates to outboard motors the power of which is less than 20 hp, since in these power classes the device can advantageously correspond to the requirements set for the steering. A steering device according to the invention is particularly suitable for steering an auxiliary outboard motor.
The steering device according to the invention comprises a connection part for connecting the steering device to a steering holder of the outboard motor and an adjustable control means is connected to the connection part for controlling the position of the steering part of the outboard motor and an electrically operated working unit is connected to the connection part for controlling the position of the control means.
According to a typical object of the invention, the steering holder is a tilt tube of an outboard motor in the mounting saddle of the outboard motor.
Typically, the control means is arranged at its connection part sided end at least partly into the tilt tube to be movable in its longitudinal direction.
According to an object of the invention, one or more electrical remote controls are connected to the electrically operated working unit for controlling the position of the control means. τhus the remote control of the outboard motor can be realized technically and economically very advantageously. The same boat can e.g. contain two electrical remote controls. Advantageously, the remote control is wireless. In this case, its use and installation is very simple and fast.
The steering device can advantageously be installed directly to existing structures. Thus, no difficult or time-consuming helm and cable installations are needed. Nor does the installation require making holes or the like to the boat. As such the installation of the steering device is also fast and technically simple. Nor is there a need to disassemble the steering device from the motor itself when moving the motor, if it is connected only to the outboard motor structures. Electrical remote control can be realized e.g. by push buttons, as a joy stick or an RF guide. It is also technically feasible to connect an electrical steering device to GPS receivers and to realize the steering arrangement as an automatic solution.
According to an object of the invention, the connection part forms a part of the body of the working unit. Then, the obtained structure is inexpensive and compact. It is also fast and easy to install to the steering holder, the tilt tube of an outboard motor.
According to an object of the invention, the working unit comprises an electrical motor, such as a direct-drive motor or a ring motor. By means of an electrical motor, the position of the control means of the invention can be simply and technically efficiently be controlled.
According to an object of the invention, the working unit comprises an electrical motor equipped with a memory. By means of such motor, it is possible to control advantageously the operation of the steering device. The device can be programmed e.g. so that when the steering device is set on, it automatically beds in to a certain position. This position can e.g. correspond to the straight direction of travel of the boat.
According to an object of the invention, a connection means is connected to the control means for connecting the steering rod of the outboard motor to the control means. Then, no separate steering rods are required but the steering rod of the outboard motor can advantageously be used.
According to an object of the invention, the control means comprises a stationary part and a transfer part that are complementary to each other, for controlling the position of the control means by moving the transfer part in relation to the stationary part. Advantageously the stationary part is a stationary thread part and the transfer part is a transfer thread part, which have complementary threads.
According to an object of the invention, the control means comprises complementary female thread stationary thread part and male thread transfer thread part, to which a clutch part is connected, and an electrical motor is connected to the clutch part, for controlling the position of the control means by turning the transfer thread part into the stationary thread part. This solution is technically advantageous to realize and it is also economically very advantageous.
A typical steering device to be mounted to a steering holder of an outboard motor comprises a control means to be mounted to a steering holder, inside the first end of which control means is fastened a nut part equipped with a female thread and at the other end of the control means there is a connection means for connecting the steering rod of the outboard motor. To the nut part of the control means is connected a threaded bar the male thread of which corresponds to the female thread of the nut part, and which first end of the threaded bar extends at least partly outside the first end of the control means. The steering device comprises a working unit at the second end of which there is a clutch part for connecting the first end of the threaded bar and a connection part for connecting the working unit to the steering holder, and at the first end of which working unit there is an electrical motor connected to the clutch part for rotating the threaded bar and for changing the position of the control means.
According to an object of the invention, at the second end of the threaded bar there is a support part for supporting the threaded bar. This support part can at the same time act advantageously as a stopper preventing the unfastening of the threaded bar while in operation.
According to an object of the invention, the steering device and/or the steering holder comprise a sealing means for sealing the joint between the steering holder and the control means. Advantageously the steering holder comprises a sealing means for sealing the joint between the steering holder and the control means. This solution improves the operating life of the device and reduces maintenance, because it prevents e.g. the entry of the corrosive sea water to the structures.
According to an object of the invention, the parts of the steering device are mainly sea water proof, such as of acid proof steel or plastic. Also with this solution the durability of the device can be improved and its need for maintenance can be reduced. In addition, more durable structures are safe in use, which is also a relevant factor e.g. when at sea.
The thread UNF 78/14 can advantageously be used in the connection part, which allows the installation of the steering device directly to the steering holder i.e. to the tilt tube, of outboard motors. The inner diameter of a standard tilt tube is approximately 16 mm (a little over 5/8"). Then, a control means can advantageously be made of 5/8" acid-proof steel, that fits directly inside a standard tilt tube. A threaded bar can e.g. be a 10 mm trapezoidally threaded bar with a 3 mm pitch. The clutch part can be made of (sea)aluminium and be equipped with a resilient part for improving the durability of the structures.
According to an object of the invention, a locking means is connected to the connection part for locking the working unit to the steering holder, i.e. the tilt tube. The locking means can be a nut in which there is a female thread that conforms to the connection part. The locking means is advantageously a tightening nut connected to the steering holder, the tilt tube.
According to an object of the invention, the connection part and the working unit that is connected thereto are supported mainly or only to the tilt tube. Then the steering device is typically connected, apart from possible remote controls, only to the structures of the outboard motor, from the connection part to the tilt tube and from the connection means of the control means via a steering rod to the steering saddle of the outboard motor.
A steering device according to the invention can advantageously be manufactured as follows:
- a control means is manufactured that is mounted to the steering holder, typically a tilt tube in the mounting saddle of an outboard motor, inside the first end of which control means is fastened a nut part equipped with a female thread and to the second end of the control means is connected a connection means for connecting the drag bar of the outboard motor, - a threaded bar is connected to the nut part of the control means, the male thread of which threaded bar corresponds to the female thread of the nut part, and which first end of the threaded bar extends at least partly outside the first end of the control means,
- a working unit is connected to a first end of the threaded bar, at the second end of which threaded bar there is a clutch part and a connection part for connecting the working unit to the steering holder, and at the first end of which working unit there is an electrical motor connected to the clutch part for rotating the threaded bar and for changing the position of the control means.
Typically the parts are manufactured so that the control means can be arranged at its connection part sided end at least partly into the tilt tube so that it can be moved inside the tilt tube in its longitudinal direction.
The method of manufacturing is relatively inexpensive, since no special tools or machines are required in addition to traditional tools of the field.
The boat is steered with the steering device according to the invention and in the method, the motor is turned a) to a first direction by arranging the electrical motor of the controller to rotate to a first direction, whereby the threaded bar rotating to a first direction moves the control means to a first direction with the help of its male threads via the female threads of the nut of the control means, which movement is translated as a movement turning the outboard motor by means of a steering rod of the outboard motor arranged to the second end of the control means, which steering rod is connected at its first end with a connection means to the second end of the control means and at its second end connected to the outboard motor,
b) the outboard motor is turned to a second direction by arranging the electrical motor of the controller to rotate to a second direction, whereby the threaded bar rotating to a second direction turns the control means to a second direction with the help of its male threads via the nut of the control means, which movement is translated as a movement turning the outboard motor by means of the steering rod of the outboard motor arranged to the second end of the control means, which steering rod is connected at its first end with a connection means to the second end of the control means and at its second end connected to the outboard motor.
With the steering device according to the invention, also the advantage is achieved that the steering can at the same time be locked to the desired position. In the device, no separate steering position lockings are needed, because the lateral forces transmitted from the outboard motor are directed to the male threads of the threaded bar and to the female threads of the nut part. The rotational forces of the bar caused by these forces are relatively low, thus they do not essentially cause rotation of the threaded bar and the electrical motor.
The invention is not meant to be limited solely to the embodiments presented above as examples but, on the contrary, the aim is to apply it extensively within the scope of protection defined in the claims below.
