Description

A NOVEL MECHANICAL STRUCTURE FOR CONTINUOUS WIRELESS POWER TRANSMISSION ON DRIVESHAFT
Technical Field
The invention relates to a mechanical structure comprising a rotating and fixed coil for wireless power transmission on a driveshaft, and an electronic circuit which is fed by the coils and collects data from the driveshaft.
In particular, the invention relates to a mechanical structure for wireless power transmission on the driveshaft, in which the rotating coil for wireless power transmission is located in the midship yoke and the fixed coil is located concentrically and at a certain distance from the rotating coil on the center bearing side by means of a fixed coil carrier adaptation part, which enables wireless power transmission without being affected by the movement of the driveshaft.
State of the Art
In the automotive field, the rotational movement and power transmission between the differential and transmission in motor vehicles is provided by the driveshaft. An electronic circuit is used on the driveshaft to transfer the measured data, and a fixed transmitter coil and a rotating receiver coil are used to provide wireless power generation to this electronic circuit.
Since the driveshaft is a transmission element that performs rotary motion, a wired connection is not possible. For this reason, the fixed transmitter coil, which is supplied from a permanent power source outside the driveshaft, must be fixedly mounted on the center bearing bracket outside the driveshaft and the rotating receiver coil must be located on the driveshaft. Electric energy is supplied to the fixed coil by cable. The center bearing bracket is used for mounting the driveshaft to the vehicle chassis and remains fixed during the movement of the driveshaft. In the state of the art, data collection on the driveshaft is only possible by temporarily attaching the transmitter and receiver coils to the driveshaft. This requires an experimental use and removal of the external elements from the driveshaft after the measurement. Therefore, there is a need for a configuration with an electronic circuit that is integrated on the driveshaft and can permanently fulfill the desired tasks. In another application where the fixed coil is placed on the mentioned center bearing bracket and the rotating coil is located on the driveshaft, the coils are permanently located on the driveshaft. In the state of the art, the systems are usually powered by a battery located on the driveshaft. There are also applications where coils are used, but in these applications, the rotating coil is winded on the driveshaft, and the fixed coil is located on the vehicle chassis. The fixed coil located on the center bearing and the rotating coil configuration located on the driveshaft cannot be removed from the driveshaft after use.
As an example of the state of the art in the literature, the document numbered TR2017/08500 applied for by us can be given. The document relates to a mechanical structure comprising a transmitter coil and a receiver coil located on a driveshaft to provide wireless power transmission. In the invention, a fixed coil carrier made of sheet metal is provided between the center bearing and the bearing for carrying the fixed transmitting coil. However, in order to install the fixed coil carrier in the aforementioned area, the design and manufacturing method of the center bearing is completely changed. This requires a configuration that allows wireless power transmission for center bearing designs that do not have a fixed carrier on the bearing.
As a result, the existence of the above problems and the inadequacy of existing solutions necessitated a development in the relevant technical field.
Object of Invention
The present invention relates to a novel mechanical structure for continuous wireless power transmission on a driveshaft, which eliminates the above-mentioned disadvantages and brings new advantages to the relevant technical field.
The main object of the invention is to provide a mechanical structure that enables wireless power transmission on the driveshaft without being affected by the movement of the driveshaft by positioning the rotating coil, which provides wireless power transmission on the driveshaft, on the midship yoke and the fixed coil at a certain distance from the rotating coil and concentrically on the center bearing side by means of the fixed coil carrier adaptation part.
The object of the invention is to provide a mechanical structure that is permanently integrated on the driveshaft. Another object of the invention is to provide a mechanical structure that enables wireless power transmission without changing the design and manufacture of the center bearing.
In order to fulfill all the objects set out above and which may arise from the detailed description, the invention relates to a mechanical structure comprising midship yoke used to provide wireless power transmission on the driveshaft, fixed to the driveshaft by connecting to the midship stub and rotating together with the driveshaft, protector carrier carrying the electronic circuit rotating together with the midship yoke on the midship yoke and collecting measurement data on the driveshaft, rotating coil carrier carrying the rotating coil which operates the electronic circuit in the protector carrier, center bearing which is connected to the midship stub and fixes the driveshaft to the vehicle chassis and remains fixed during the rotational movement of the driveshaft, and fixed coil which provides power transfer to the rotating coil, the mechanical structure comprises: fixed coil carrier adaptation part connected to the center bearing, fixed coil carrier, which is located in the fixed coil carrier adaptation part and carries the fixed coil.
The structural and characteristic features and all the advantages of the invention will be more clearly understood by means of the figures given below and the detailed description written by making references to these figures. Therefore, the evaluation should be made by taking these figures and the detailed description into consideration.

Detailed Description of the Invention
In this detailed description, the preferred embodiments of the mechanical structure of the invention are described solely for the purpose of a better understanding of the subject matter and without any limiting effect.
Figure 1 shows a disassembled view of the mechanical structure of the invention. Accordingly, the mechanical structure in the most basic form includes; midship yoke (10) which is fixed to the driveshaft by being connected on the midship stub (100) and rotates together with the driveshaft, protector carrier (20) carrying the electronic circuit (90) which rotates together with the midship yoke (10) on the midship yoke (10) and collects measurement data on the driveshaft, rotating coil carrier (30) carrying the rotating coil (40) which operates the electronic circuit (90) in the protector carrier (20), a center bearing (50) which is connected to the midship stub (100) and fixes the driveshaft to the vehicle chassis and remains fixed during the rotational movement of the driveshaft, a fixed coil (80) which is connected to the center bearing (50) and provides power transmission to the rotating coil (40), and a fixed coil carrier adaptation part (60) which holds the fixed coil carrier (70) carrying the fixed coil (80).
The midship yoke (10), which is the unit element of the driveshaft, is fixed to the driveshaft by connecting to the midship stub (100) and performs rotational movement together with the driveshaft. As can be seen in Figure 2, a protector carrier (20) is connected to the midship yoke (10), which performs rotational movement together with the midship yoke (10). The protector carrier (20) protects the mechanical structure from environmental effects by carrying the electronic circuit (90) that collects measurement data from the driveshaft. At the same time, a rotating coil carrier (30) is placed in the protector carrier (20) on which the electronic circuit (90) is located. The rotating coil carrier (30) carries the rotating coil (40) which operates the electronic circuit (90). The rotating coil carrier (30) carrying the rotating coil (40) performs rotational movement together with the protector carrier (20) which performs rotational movement together with the midship yoke (10).
The midship stub (100) is provided with a center bearing (50) which secures the driveshaft to the vehicle chassis and remains fixed during rotational movement of the driveshaft. The center bearing (50) is located on the midship stub (100) opposite to the midship yoke (10). As shown in Figure 3, the fixed coil carrier adaptation part (60) is connected to the center bearing (50). For this purpose, carrier arms (61) extend outwardly from the periphery of the fixed coil carrier adaptation part (60). By means of the fixed coil carrier adaptation part (60) being connected to the center bearing (50) by means of the carrier arms (61), the center bearing (50) maintains its position during operation under the vehicle and is not affected by the axial and radial movements of the center bearing (50), which makes axial and radial movements due to shock loads caused by the engine of the vehicle or forces on the driveshaft.
In the fixed coil carrier adaptation part (60), a fixed coil carrier groove (62) is formed. By means of the fixed coil carrier groove (62), the fixed coil carrier (70) carrying the fixed coil (80) providing power transmission to the rotating coil (40) is fixed inside the fixed coil carrier adaptation part (60). As seen in Figure 4, the fixed coil (80) on the fixed coil carrier (70) remains fixed on the driveshaft and does not rotate. The fixed coil (80) receives its energy from a power source and transmits it to the rotating coil (40), and the rotating coil (40) provides wireless power transfer to the electronic circuit (90) to supply and operate the electronic circuit (90). By the fixed coil carrier adaptation part (60), the fixed coil (80) is located at a certain distance from the rotating coil (40) and concentrically on the center bearing (50) side.
On the fixed coil carrier adaptation part (60), voids (64) are formed to prevent damage to the rubber connection part connecting the center bearing (50) and the bearing assembly (51) in the center bearing (50) by the fixed coil carrier adaptation part (60) and restriction of the radial and axial movement of the center bearing (50). The cables connecting the fixed coil (80), which receives its energy from a power source, with the power source are located on the fixed coil carrier adaptation part (60) by means of the cable groove (63) located on the fixed coil carrier adaptation part (60).
