Description

Mounting bodies for watercraft

Technical area

The invention relates to a fastening body at the rear of a watercraft according to the preamble of the first claim.

State of the art

Attachments at the stern of a watercraft are well known as e.g. permanently mounted or height-adjustable floating platforms, frame racks for small outboard motors or spacers for holding larger outboard motors with integrated floating platforms, as well as rear-mounted transaxle housings.

The variety of devices that can be found in the rear of a watercraft today - to enumerate here just a few of the above-mentioned - Z drive, trim tabs, rudder, depth sounder, speedometer, engine cooling water inlet and exhaust, engine exhaust, require ever more complex installation work. Many of the moving equipment such as trimming cylinders for Z-drives, trim tabs, variable floating platforms, rudder are operated by hydraulic cylinders and increasingly have position sensors, ie a large amount of hydraulic lines and sensor cables must be additionally installed in the vessel interior. Also, the hydraulic leakage risks and the associated water pollution of more and more fluid-controlled elements on a watercraft are significantly increasing. Presentation of the invention

The invention has for its object to avoid the disadvantages of the prior art in a mounting body for watercraft of the type mentioned.

According to the invention this is achieved by the features of the first claim.

The core of the invention is that the fastening body is designed as a carrier for technical means and or propulsion medium.

The fact that the fastening body is designed as a carrier for technical means and or propulsion medium, the fastening body can assume a variety of functions.

This configuration results in a variety of advantages.

By attaching the fastening body as an additional rear element, this can be formed as a hollow body and having inner ribs for holding the various technical means. Control cables and cables can be routed cleanly and bundled through an opening above the waterline into the interior of the vessel. Technical means accommodated in the hollow body of the fastening body and / or propulsion medium which emit vibrations and noises may be decoupled from the original water vehicle by means of a vibration damper.

In addition, the additional rear element at the same time also a buoyancy function, similar to a lengthened watercraft hull in simple or stepped form, meet. The advantage is also in the professional separate installation of all technical components in such an additional rear element and Vorabtesten the devices before mounting on the vessel, so that the whole ultimately tested and can be mounted by a few handles directly to the rear of the vessel. In addition, the cables can also be prefabricated and brought into operation by simply plugging or direct connection with the main units _. become. By means of the fastening body, for example, the technical devices such as drive, steering, trim, engine cooling and exhaust system, but also variable floating platform, Aufbockelemente and other technical complex control and rotating parts integrated directly into its hollow body and eg rotating means such as thrusters or Propulsionsanlagen means on the mounting body mounted vibration damper noise and vibration attenuated resp. be isolated. Nevertheless, the thrust can be absorbed in any direction.

Further advantageous embodiments of the invention will become apparent from the other dependent claims.

Way to carry out the invention

Fig. 1 shows a schematic cross section through part of a stern 1 of a watercraft 1 a and the fastening body 2, which exemplifies a

Z drive as propulsion medium PM with exhaust gas guide 3a and cooling water intake 3b and a transverse thruster 4 carries, wherein the mounting body 2 elastically by means of a vibration absorber 5, e.g. a polyurethane elastomer or a vulcanized rubber mixture from the rear 1 of the watercraft 1a is decoupled, but at the same time also contributes to the connection of the fastening body 2 with the rear 1. The or more vibration absorber 5 also take over the shear forces of Propulsionsmittels PM, as well as possible transverse and tensile forces. The vibration absorber 5 can also be installed vertically or transversely, in order to achieve the greatest possible vibration and noise reduction.

Due to the vibration-damping mounting of the fastening body 2 evt the situation arises that the motor shaft 3c is not always aligned with the transmission shaft 3d, therefore, by means of a cardan shaft 3e via 2 cardan joints, i. Angular compensators 3f, possible misalignment compensated. Due to the mounting body 2, it is no longer required at the rear 1 a large mounting cutout for the propulsion PM, but only a small opening for the motor shaft 3c or propeller shaft 3e, which prevents water penetration into the interior of the watercraft 1a by means of an elastic bearing seal 3.
