Description

Inboard and outboard

The present invention relates to an inboard and outboard engine, especially one that is easy to operate and easy to control the depth of the propeller protruding into the water, so that the contact condition with the water surface can be changed at any time, so that the ship can travel in waters with different depths and improve the propulsion of the ship. One of the fastest inboard and outboard motors.

According to, the power system used in small and medium-sized ships used to be mostly outboard motors, but in recent years it has gradually been replaced by outboard motors. The main reason is nothing more than; The stern of the ship with inboard and outboard motors can be vacated, so that the space at the stern of the ship can be effectively used, increasing the overall use space of the ship; the hull with inboard and outboard motors has no external outboard motors, so the integrity of the hull is highly aesthetic; Because the outboard motor is installed at the bottom of the ship, it has better low noise performance than ships using outboard motors, and this advantage is especially popular in the yachting industry.

As shown in [Figure 1], an outboard and outboard engine 1 is mainly to install the engine 11 in the cabin 12, and the stern engine 13 is installed outside the ship. Traditionally, this design has the above-mentioned advantages over outboard engines. Many advantages, but still have its disadvantages; it is mainly that the inboard and outboard motor 1 cannot be tilted, because the inboard and outboard motor 1 is mainly to arrange the engine 11 in the cabin 12, and the stern motor 13 is installed outside the ship, so that The internal and external engine 1 cannot tilt the entire stern engine 13 to allow the engine 11, propeller 131 and other components to leave the water surface. It is relatively difficult to carry out repair work on these devices, which often increases the hours of repair work and construction costs. .

For this reason, it is obviously necessary to further design the inboard and outboard unit 1 so that it can not only keep In addition to the original advantages, it can also overcome the disadvantage that the internal and external machine 1 cannot tilt the propeller 131 of its stern machine 13 and other components to leave the water surface.

The present invention relates to an inboard and outboard motor, which mainly overcomes the disadvantage that the traditional inboard and outboard motor cannot adjust the depth of its propeller protruding into the water, which makes the boat unable to cope with waters of different depths, and even hinders the repair and maintenance work.

For this reason, the invention provides an outboard and outboard machine. The inboard and outboard engine of the present invention at least includes an engine, a cardinal device, a propeller, a lifting device and a steering device, wherein;

The engine also has a power drive shaft to output power to the outside;

The cardinal device has at least a seat, a universal joint group, a sleeve and a positioning ring; the seat has a gear set and a pair of hollow nozzles that are open to the outside, and the gear set is connected with the power drive shaft of the engine , the universal joint group has a first connecting rod and a second connecting rod, the first connecting rod is connected with the gear set, the sleeve is used to cover the universal joint group, and one end of the sleeve has an inner Hollow arc-shaped shell body, the other end of the sleeve extends into a cylinder, and the cylinder has a central shaft hole running through its axial direction, and the central shaft hole is used for the second connecting rod of the universal joint group to pass through; positioning The ring and the nozzle of the seat are fixed, so that the universal joint group and the sleeve can be fixed; the propeller has at least one transmission shaft and one propeller, one end of the transmission shaft is used for assembly with the pivot device, and the other end of the transmission shaft Then it is combined with the propeller; the lifting device has at least one hydraulic cylinder, and one end of the hydraulic cylinder is pivotally fixed on the propeller; the steering device has at least a moving part, a connecting rod and a rotating shaft, and the moving part is connected Connect, the connecting rod is connected with the rotating shaft in addition, and the rotating shaft is connected with one end of the hydraulic cylinder.

The power drive shaft of the engine is connected to the gear set of the cardinal device, so that the power of the engine can be transmitted to the gear set of the cardinal unit through its drive shaft, and the power is continued through the cardinal The universal joint group of the device is passed to the propeller so that the propeller can run smoothly, and the hydraulic cylinder of the lifting device can make the propeller lower down with the universal joint group as the fulcrum, so that the propeller of the propeller sinks in the water To drive the hull forward, and then operate the moving parts of the steering device to move the left and right sides. When the moving parts start to move, the connecting rod of the steering device will rotate the shaft accordingly. When the shaft rotates, the The propeller will swing left and right with the universal joint group as the fulcrum, so that the boat can turn smoothly when driving in the water.

The application effect of the present invention that can be produced by the above-mentioned structure is that the present invention controls the hydraulic cylinder of the lifting device to move the propeller that can control the thruster to sink into the water to drive the ship to move forward, and further controls the propeller to sink into the water. The depth of the water can be used to prevent the propeller of the propeller from hitting the bottom of the water and be damaged when the ship is driving in extremely shallow waters; moreover, the propeller can be raised to completely out of the water, so as to respond to the water surface of the ship. When mooring, or for repairs and maintenance, or even when leaving the water.

Another application effect of the present invention that can be produced by the above-mentioned structure is that when the propeller is controlled to make the propeller go deep into the water, the resistance suffered by the propeller and the ship will increase, so that the ship can be lowered. The effect of speed, and when the propeller is raised near the water surface, the resistance on the propeller and the ship will be reduced, so that the speed of the ship can be accelerated, so that the ship can not only be output by the engine In addition to controlling the speed of the ship by power, the purpose of changing the speed of the ship can also be achieved by changing the depth at which the propeller of the propeller sinks into the water.
