Description

Outboard engine support tube for cable {OUTBOARD ENGINE SUPPORT TUBE FOR STEERING CABLE}

[0001] The present invention relates to an outboard engine support tube for a cable, and more particularly to a support tube for an outboard engine for a cable, in which a cable is connected to a tilt tube attached to an outboard engine, To an outboard engine support tube for a cable that provides operational simplicity.

The outboard engine is a propulsion engine mounted on a transom that forms the back side of a ship such as a small boat. Depending on the direction of operation of the outboard engine, the propulsion direction of the ship changes.

Nearly all outboard engines except some low horsepower outboard engines are equipped with a tilt tube. In this case, the mechanical steering system (cable steering) moves the cable in the tilt tube and moves the entire outboard engine. The rod end of the cable and the tiller arm of the outboard engine are connected by a linkage, and the cable is moved according to the operation of the steering handle, thereby steering the outboard engine.

However, due to the characteristics of the outboard engine mounted on the outside, the tilt tube is always exposed to the external environment, so that the foreign material easily penetrates. In addition, if the movement of the cable is not always checked by supplying lubricant to the cable in the tilt tube, the lubricant tends to cling to the inside of the tilt tube, so that the cable does not operate properly inside the tilt tube.

Also, when attaching the cable to the tilt tube of the outboard engine, it is necessary to make a hole through the cable to the splashwell side of the starboard of the ship and to pass the cable through the hole. However, in many cases, the gap between the side wall and the tilt tube is narrow, and the cable installation is impossible in this manner. In this case, the outboard engine must be detached from the transom, and then the cable must be connected to the tilt tube and the outboard engine must be mounted on the transom again.

The tilt tube 30 is formed in the shape of a cylinder, and the tilt tube 30 is fixed to the outboard engine 20 and fixed to a length of about 11 to 12 inches. In a normal steering apparatus, a cable is connected so as to penetrate through through holes formed in a tilt tube, and the cable is steered through a steering handle.

An outboard engine support tube 10 for a cable according to an embodiment of the present invention is positioned on an axial side surface of a tilt tube 30 attached to an outboard engine 20. [ At this time, the cable outboard engine support tube 10 may be installed parallel to the axis of the tilt tube 30.

An outboard engine support tube 10 for a cable according to an embodiment of the present invention includes a cylinder 11 such as the shape of a tilt tube 30. A through hole 12 is formed in the inside of the cylinder 11 and the cable 13 reciprocates along the through hole 12.

A steering handle 15 is provided at one end of the cable 13. When the cable 13 linearly reciprocates according to the operation of the steering handle 15, the rod end 19 And the tiller arm 21 attached to the outboard engine 20 are connected to each other through the linkage 23 so that the tiller arm 21 connected to the rod end 19 is moved in accordance with the movement of the rod end 19 of the cable 13 And the outboard engine 20 to which the tiller arm 21 is attached is operated. Thus, the movement direction of the ship can be adjusted through the operation of the outboard engine 20.

Meanwhile, the length of the outboard engine support tube 10 for a cable according to the embodiment of the present invention is preferably shorter than that of the tilt tube 30.

Generally, the length of the tilt tube 30 attached to the outboard engine 20 is standardized, and it is difficult to control the width of the ship. Therefore, when an outboard engine support tube 10 for a cable shorter than the tilt tube 30 is separately installed and the following bushing member 1 and sealing member 7 are mounted to insert and operate the cable 13 The cable 13 can be smoothly operated.
