The present invention relates to a steering wheel system for a motorboat, and more particularly to improve the reliability of the steering wheel system by improving the structure of the cable and the housing constituting the steering wheel system.

In general, the steering wheel system (steering wheel system) is used where the steering, such as motorboats, jet skis, including an automobile, the system structure will vary depending on the device.

 Looking at the structure of the steering wheel system of the motor boat, a steering wheel (steering wheel) for maneuvering the course in the desired direction, a helm (transmitted helm) for transmitting the operating force of the steering wheel to the gearbox, the gearbox meshing with the helm And a power transmission cable installed between the gearbox and the engine so as to remotely adjust the direction of the engine through the gearbox.

At this time, the structure of the cable is a core wire (core wires) of the various wires, a liner (liner) surrounding the core wire, conduit wires (conduit wires) surrounding the liner, a conduit (conduit) surrounding the conduit wire It is composed of

In addition, an armor is coated on the entire outer circumferential surface of the core wire to prevent it from being destroyed by abrasion.

The glove is wound in the form of a spiral band, and a pitch is formed between turns and turns of the glove so that the flexibility of the core wire can be maintained even when the glove is coated. In the above process of adjusting the direction of the engine through the structure of the steering wheel system, the operating force of the steering wheel is transmitted to the helm and the gearbox, the operating force transmitted to the helm and the gearbox to the cable installed between the gearbox and the engine Is delivered to the engine.

However, the following problems occur in the conventional steering wheel system.

First, there is a problem according to the structure of the cable.

That is, the cable installed between the gearbox receiving the operating force of the steering wheel and the engine generating power is preferably installed in a straight state, but due to the design characteristics due to interference with other devices or structures, the cable is bent according to the section. As installed, the core wires that make up the cable are also installed to move along the bent liner and conduit.

On the other hand, in the process of repeatedly operating the steering wheel to adjust the direction of the engine, the core wire is repeatedly subjected to compressive and tensile forces, and at the time of compressive force, the connection portion of the core wire to the gearbox is bent backwards. This results in more compression than other parts of the core wire.

In other words, the bending force is easily generated in the straight portion of the core wire directly connected to the gearbox due to the propulsion force of the core wire generated in the curved section and the compressive force is directly transmitted.

Therefore, it is necessary to allow the core wire to bend more flexibly in the curved section so that the core wire moves without bending even in a smaller compression force in the straight section directly connected to the gear box.

However, the existing cable is armored over the entire length of the core wire, causing an unnecessary large brace in the curve section.

Accordingly, a larger compressive force is applied to the core wire for the steering wheel operation, which causes a problem of intensively bending in a straight section connected to the gearbox of the core wire to promote wear due to interference with the linear.

As described above, when bending occurs in a straight section of the core wire due to the compressive force applied to the core wire too largely, wear of the armored portion of the core wire becomes severe.

In particular, in an engine running state in which the motorboat speeds at 100 km / h or more, the vibration of the engine increases the wear of the armor portion of the core wire, which causes the core wire to be broken more quickly.

In addition, there is a problem in accordance with the pitch interval of the gloves coated on the core wire.

That is, in addition to the above-described problem caused by the overall glove made of the core wire, there is a problem according to the pitch interval.

The pitch spacing of the glove coated over the core wire of the cable is slightly spaced between each turn so that the core wire is bendable, as described above, so that the core wire installed between the gearbox and the engine is in line with the shape of the cable installation section. Or to be able to transfer the force well in a bent state.

For this reason, the core wire is bent well in the curved section, but there is a disadvantage that the straight section of the core wire connected to the gearbox is also easily bent when the compressive force is applied.

In this case, the wear of the gloves is accelerated and the life of the core wire is shortened. In other words, the straight section connected to the gearbox of the core wire is advantageous to reduce the wear of the core wire even when the compressive force is maintained, and the rest of the straight section connected to the gearbox of the core wire is curved. When entering the section, it is easier to bend than before, which is advantageous for extending the life of the core wire and transmitting force.

On the other hand, in the conventional steering wheel system, as described above, as the slider is moved by the steering wheel while bending occurs in a straight section of the core wire connected to the gearbox, the interference force between the core wire and the liner is increased. The end cap is transmitted to the connecting member and the end cap, and the end cap acts as a force to open the housing end, and the housing end is damaged as this action is repeated for a long time.

For reference, if the housing end is broken, the linear motion of the core wire cannot be controlled and the steering wheel system loses its function.

The present invention is to solve the above problems, the present invention improves the durability of the cable and the housing by improving the structure of the cable and the housing constituting the steering wheel system, it is possible to increase the overall reliability of the steering wheel system The purpose is to make it.

In order to achieve the above object, the present invention is a cable is installed between the gearbox and the movable part so as to adjust the direction of the movable part by receiving the operating force of the steering wheel through the helm and the gearbox, the cable is a rigid response ( A motor boat provided with a core wire twisted and heat treated to have a rigid response, a liner surrounding the core wire, a conduit wire surrounding the liner, and a conduit surrounding the conduit wire to adjust the direction of the movable part. For a steering wheel system; Of the entire length of the core wire, the outer peripheral surface of the core wire from the starting point to the predetermined portion connected to the gearbox is armored, the rest of the steering wheel system for a motor boat characterized in that the coating is coated with a synthetic resin material This is provided.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 8.

In addition, Figure 5 is a cross-sectional view along the line I-I of Figure 4b, Figures 6a to 6c is an action diagram showing the action of the slider according to the operation of the steering wheel system for boats of the present invention, Figure 7 is a view of Figure 6a It is an expanded sectional view which shows part A, and FIG. 8 is sectional drawing II-II of FIG.

Referring to these drawings, first, as shown in FIG. 1, the motor boat MO may include a hull 100 on which a person rides, a steering wheel 10 for adjusting a direction of the motor boat MO, and , Helm 20 and the gear box 30 for transmitting the adjustment direction of the steering wheel 10, the cable 40 for adjusting the adjustment direction received through the helm 20 and the gear box 30 and And, the direction is adjusted by the cable 40 and comprises an engine (E) for generating power to maintain the rotational force of the propeller.

At this time, the steering wheel system 1 of the present invention, as shown in Figure 2, consists of the steering wheel 10, the helm 20 and the gearbox 30, the cable 40.

Looking at the configuration of the steering wheel system in more detail, the steering wheel 10, the helm 20 which is a steering device for transmitting the operating force of the steering wheel 10 to the gearbox 30, and the steering wheel The operating force of the 10 is transmitted through the helm 20 to the gearbox 30 for transmitting to the engine E through the cable 40, and received through the gearbox 30 to direct the direction of the engine E. It is composed of a cable 40 between the gearbox 30 and the engine (E) to adjust, the cable 40 is a core wire 41, and a liner 42 surrounding the core wire 41 and And a conduit wire 43 surrounding the liner 42 and a conduit 44 surrounding the conduit wire 43.

On the other hand, the gearbox 30, the housing 31; A slider upper (32) having a rack (32a) which is installed to be movable inside the housing (31) and is engaged with the helm (20) for transmitting the operating force of the steering wheel (10); A slider lower (33) for sealing an open portion at the bottom of the rack (32a); A rod 35 connected to one end of the core wire 41 on which the glove 50 is wound and positioned at a portion at which the slider lower 33 is coupled; It comprises a fitting member 34 for connecting the glove 50 is connected to the wound core wire (41). The combination of the slider upper 32 and the slider lower 33 is called a slider. At this time, a wide helical coupling groove 31a is formed at one surface of the central portion of the housing 31, and a fixed groove 31b having a long hole is formed at one end of the housing 31, and one end of the slider upper 32 is formed. A through hole 32b is formed in the rod 35 through which both ends of the rod 35 can span.

 In addition, the fitting member 34 is formed such that when the hammering (hammering), the cross-sectional shape of the fitting member 34 forms a circular shape. Meanwhile, the glove 50 wound in the form of a thread on the core wire 41 is preferably formed from a connection point with the gearbox 30 to a point immediately before entry of the first curved section, in which the first of the core wire 41 is formed. Since the point immediately before entering the curved section varies depending on the position of the slider, more precisely, it is formed from the connection point of the gearbox 30 to the point just before the first curved section entry when the slider pushes the core wire 41 to the maximum. desirable.

The distance from the connection point of the gear box 41 to the first curved section is preferably equal to or greater than the stroke of the slider.

On the other hand, the gearbox 30, and the cylinder (36) is installed in the housing (31) passing through the section in which the glove (50) is coated on the cable (40); A connection member 37 connecting the cylinder 36 and the conduit 44 passing through the cable 40; The connection member 37 is configured to further include an end cap 38 to be fixed in a state inserted into one end of the housing (31).

At this time, the end cap 38 is inserted into one end of the housing 31 divided into upper and lower parts.

In addition, even if the bending of the core wire 41 occurs outside the portion where the end cap 38 of the housing 31 is installed, the interference between the core wire 41 and the housing 31 occurs. The end cap 38 is preferably configured to further include a reinforcing cap (39) to prevent the end of the installed portion is not opened or broken while preventing the end cap.

Here, when one portion of the upper and lower surfaces of the reinforcing cap 39 is pressed by an external force in the state in which the reinforcing cap 39 is coupled to one side and the bottom of the housing 31, the protrusion 31 protrudes into the cap. A fixing groove 31b is formed to catch the portion 39a to prevent the reinforcement cap from being separated from the housing.

The operation of the steering wheel system 1 for a motor boat of the present invention configured as described above will be described with reference to each steering state of FIGS. 6A to 6C.

First, FIG. 6A is a state where the direction of the engine E is placed in a neutral position.

That is, the helm receiving the operating force of the rack 32a of the slider upper 32 and the steering wheel 10 positioned inside the housing 31 through the coupling groove 31a opened on the housing 31. 20) is engaged, the slider located inside the housing 31 is located in the center of the housing.

Next, FIG. 6B shows that the slider is moved from the inside of the housing 31 to the opposite end of the cable connection so that the direction of the engine E is adjusted to the left end (see FIG. 1).

That is, when the steering wheel 10 is rotated in the counterclockwise direction, the slider engaged with the helm 20 slides toward one side of the housing 31 and the engine E connected to the core wire 41 is pulled to the left direction. To move.

Next, referring to FIG. 6C, the slider moves from the inside of the housing 31 to the end of the cable 40 so that the engine E is adjusted to the right end while the direction of the engine E is adjusted. It is in a state.

That is, when the steering wheel 10 is rotated as far as possible in the opposite direction (ie, clockwise direction), the slider engaged with the helm 20 is slidably moved to the other side of the housing 31, and the engine connected to the core wire 41 ( E) is pushed to the right.

Meanwhile, a process of connecting the rod 35 and the core wire 41 provided in the gearbox 30 will be described with reference to FIGS. 4 and 5.

First, one end of the rod 35 provided between the slider upper 32 and the slider lower 33 moved inside the housing 31 to both sides of the fitting member 34 is positioned, and the core wire is positioned. A portion of the 41, in which the glove 50 is coupled to one end of which is not coated with the nylon 60, is positioned as shown in FIG. 4A.

Next, one end of the rod 35 is inserted into one side of the fitting member 34, and one end of the core wire 41 to which the glove 50 is coupled is inserted into the other side of the fitting member 34.

In this state, a hammering operation is performed on the entire outer circumferential surface of the fitting member 34 to be connected as shown in FIGS. 4B and 5.

At this time, the fitting member 34 is hammered so that the cross-sectional shape has a circular shape to connect one end of the core wire 41 to the rod 35. Unlike the conventional hammering operation, a uniform force is applied to the entire outer circumference at the same time to achieve a precise circular shape without distortion of the cross-sectional shape.

In the above, the process of adjusting the direction of the engine E according to the action of the gearbox 30 has been described with reference to FIGS. 6A to 6C. The process of connecting the gearbox 30 and the cable 40 to FIGS. As described with reference to 4b and 5, looking at the action of the present invention to prevent the wear caused in the core wire 41 portion of the cable 40 located on the gearbox 30 through these processes As follows.

The cable 40 installed between the gearbox 30 section and the engine E section is installed as shown in FIG. 1 with a combination of a straight section and a curved section.

In this case, a predetermined section of the outer circumferential surface of the core wire 41 located on the gearbox 30 is provided with a glove 50.

Precisely, the glove 50 is preferably formed from the point of connection with the gearbox 30 of the core wire 41 to the point just before entering the first curved section when the slider pushes the core wire 41 as far as possible. .

Therefore, the portion of the core wire 41 not provided with the glove 50 flexes flexibly over the entire section.

As a result, unnecessarily large propulsion force is not generated in the curved section, and the compression force and tension force repeatedly applied to the core wire 41 in the process of repeatedly manipulating the steering wheel 10 to adjust the direction of the engine E. At the time when the compressive force is applied, that is, in the curved section, unlike the conventional glove is not formed, so the support force of the core wire 41 is significantly reduced, so that the core wire 41 directly connected to the gearbox 30 when the steering wheel is operated. The straight part of the is not easily bent.

Accordingly, since no bending occurs in the straight section of the core wire coated with the gearbox 30 directly, the interference with the liner 42 is also reduced, and eventually, the wear caused by the interference with the liner is effectively prevented. do.

In particular, in the existing motor boat operating the engine (E) at a speed of 100km / h or more to increase the occurrence of wear generated in the glove 50 of the core wire 41 due to the vibration of the engine (E), Although breakage is promoted, in the present invention, the effect of preventing breakage of the core wire at high speed can be enhanced.

On the other hand, one of the other factors contributing to the prevention of wear of the core wire is that the pitch interval of the glove is configured to be tight. That is, the portion of the glove 50 coated on the core wire 41 refers to the point just before the first curved section entry at the time when the slider pushes the core wire 41 as far as possible from the connection point of the gearbox 30. At this time, the pitch spacing of the glove 50 is more tightly coated than the conventional, so that it does not easily bend and maintains a straight state.

For this reason, the force is transmitted as it is when the direction of the engine E is changed according to the operation of the steering wheel 10, and the direction is more smoothly changed.

Next, the action of the coated nylon in the section where no gloves are worn will be described. Nylon 60 coated in the entire section of the glove 50 is not coated, the salt of the sea water is the core wire in the course of the continuous exposure of the core wire 41 coupled to the engine (E) in the high salt water 41) to prevent rusting by preventing it from penetrating.

Next, the effect of the end cap 38 for dividing and fixing the connection member 37 up and down on one side of the housing 31 will be described.

Interference between the core wire 41 and the liner 42 is generated while the slider is repeatedly moved by the steering wheel 10 in a straight section of the core wire 41 connected to the gearbox 30.

In this process, the interference force between the core wire 41 and the liner 42 is transmitted to the end cap 38 fixing the connecting member 37 to act as a force against the end of the housing 31.

In addition, if the end of the housing 31 is damaged as this action is repeated over a long period of time, the linear movement of the core wire 41 becomes impossible to control, and the steering wheel system 1 loses its function.

Accordingly, the reinforcement cap 39 is shown in FIGS. 7 and 8 to prevent the end of the housing 31 from being broken or the end cap 38 that secures the connecting member 37. (31) is coupled to surround one side.

Meanwhile, 340, which is not described in FIG. 1, is a fitting member for connecting a portion connected to the core wire 41, 350 is a rod connected to the core wire 41, and 360 is wrapped around the rod 350. A fixed cylinder, 370 is a cylinder sliding in the core wire 41, 380 is a fixing member for fixing the cylinder 370 so as not to be separated from the core wire 41, 390 connects the engine (E) It is a connecting member.

The present invention as described above has the following effects.

First, the present invention is to maintain the straight distance by applying the glove 50 from the connection point of the gearbox 30 to the point just before entry of the first curve section at the time the slider pushed the core wire 41 as far as possible, For the rest of the glove 50 will not be coated.

As a result, the portion of the core wire 41 to which the glove 50 is not coated is flexibly bent in the bending section, and at the same time, the compressive force and the tensile force are reduced to reduce the compressive force transmitted to the glove 50 maintaining the straight distance. It is effective to prevent wear.

Second, the present invention increases the strength of the glove 50 coated on the portion connected to the gear box 30 so as not to be bent tightly, it is more effective to prevent the wear easily bent by the compressive force.

Third, the present invention is repeated for a long time by the end cap 38, which fixes the connecting member 37 by the interference force between the core wire 41 and the liner 42 acts as a force against the end of the housing 31 The reinforcement cap 39 reinforces that the end of the housing 31 is broken or the end cap 38 is opened, thereby making it impossible to control the linear movement of the core wire 41 as well as the steering wheel system 1 functions. It is effective to prevent the loss of.

Fourth, the present invention by using the glove 50 coated on the entire core wire 41 connected to the gear box 30 in the required section, it is possible to reduce the cost to cut the cost of production very big.
