DESCRIPTION OF THE INVENTION

1. Invention scope:

Rotary parking is intended for vehicle parking covering the ground floor area of two parking spaces. It is intended for parking a vehicle with a maximum weight of 2500 kg and 1.9 m height, width up to 2.2 m.

This invention relates to an electric motor drive for vertical rotary parking for cars (abbreviated as RP6, RP8, RP10, RP12, RP14, RP16, RP20) RP rotary parking marked RP and number of parking platforms (gondolas) with use of planetary gear units.

2. Technical problem

(whose solution requires patent protection)

Up to now the motor power transfer was primarily solved by using an additional transmission (chain, gear, etc.) along with the gearmotor on one side and possibly additional transmission (chain, gear, etc.).

This additional engine power transfer was performed on both sides of the rotary parking (front and rear of the rotary parking unit).

From the gearmotor the moment (engine power) on one side should be transferred to the other side (where there is no drive motor) and this required a larger drive shaft which significantly increased the transmission itself (because a big moment is transferred).

This solution seeks to achieve a more even transmission of the drive power of the drive with the gear unit through the proper positioning of the drive motor and the use of planetary gears to regulate the engine power needed to run the sprocket that drives the drive chains carrying parking platforms (gondolas).

3. Engineering conditions

(visualization and analysis of known solutions of a defined technical problem)

In recent years, there were solutions to this problem by transferring the power of a propulsion engine that was located on one side of a rotary parking unit and it was to be transferred to the other side for which a large drive shaft was used, which significantly affected the cost of rotary parking.

So far, the power transmission of the motor has been solved in such a way that, along the gearmotor on one side, the additional gear (chain, gear transmission etc.) and even additional transmission (chain, gear, etc.) was used. This additional engine power transfer was performed on both sides of the rotary parking (front and rear of the rotary parking unit).

4. Presentation of the core of the invention

(so that the technical problem and its solution can be understood, and pointing out the technical novelty of the invention with respect to known solutions)

With rotary parking deployment, parking space requirements are reduced by 8, 10 and more times compared to the traditional parking. Released surfaces can be used for other purposes (green areas, parks).

The primary objective of the invention is to improve engine power transmission evenly on both sides (front frame (1) and rear frame (2) of rotary parking with planetary gear units (mark 9) on both sides of rotary parking.

The secondary goal is to ensure the greater use of rotary parking in normal life, with the provision of sufficient number of parking spaces where this is needed through the production of an economically acceptable parking system (rotary parking).

A further objective of the invention is to allow greater use of rotary parking in normal life. Additional goals and advantages of the invention will be illustrated in the following description:

The rotary drive system (5) with two planetary gears (9) at the end through the sprockets (10) drive lances (4) on which the car platforms-gondolas (3) are connected.

The drive is dimensioned so that it can run the platform-gondola (3) even when all cars are on one side of the parking system.

With full load, i.e. when all platforms are filled, there is not so much load on the engine as practically the chains with the gondolas are in balance.

The drive system consists of the main engine with a gear unit (mark 6) and two planetary gear units (mark 9) on which the sprockets (mark 10) for the chain drive (4) are mounted on the output axles and two axles (mark 7) that, through couplings (8), transmit the power of the main engine to the planetary gearbox.

The main engine itself has a brake that holds the whole system locked while the engine is not running.

The entire drive system is attached to the lower beam (mark 11) of the link joining the front and rear frame (marks 1 and 2) of the rotary parking structure.

The lower beam is reinforced in this section to accommodate the main drive motor and planetary gear units. 5. Brief description of the drawings

6. A detailed description of at least one mode of achieving the invention

Now, we will show the details of the invention which is a much more economical and rational transfer of power from a drive motor with a gear unit located on one side of a rotating parking lot.

The proposed electric motor drive system (5) consists of the main motor with a gear unit (6) and two planetary gears (9) on which the sprockets (10) for the chain drive (4) are mounted on the output shafts, and the two shafts (7) that through couplings (8) transmit the power of the main engine to planetary gear units.

The main drive motor has a brake that holds the whole system locked while the engine is not running.

The entire drive system is attached to the lower coupling beam (11) connecting the front (1) and rear frame (2) of the rotary parking structure.

The lower beam (11) is reinforced in this section for receiving the main drive motor (6) and planetary gear units (9).

So far, the power transmission of the motor has been solved in such a way that, along the gearmotor on one side, the additional gear (chain, gear transmission etc.) and even additional transmission (chain, gear, etc.) was used.

This additional engine power transfer was performed on both sides of the rotary parking (front and rear of the rotating parking unit).

From the gearmotor the moment (engine power) on one side should be transferred to the other side (where there is no drive motor) and this required a larger drive shaft which significantly increased the transmission itself (because a big moment is transferred).

The essence is that by using a planetary gearbox this has been solved in the way that the gearmotor with gear reducer sets in the middle of the system and thus enables equal power transmission of the engine to the front and rear side of the parking system i.e. to the planetary gears in which the number of rotations is considerably reduced and the moment required for launching the chain with gondolas is increased.

On the output shaft of the planetary gears (9), the corresponding sprocket (10) engages the bolts (13) on the transmission chain (4) and thereby triggering the gondolas (3).

In this way, the purpose of transmitting the power of the drive motor with the gear unit (6) to the transmission lances (4) with gondolas (3) is achieved.

7. The mode of deployment of the invention

In this way, by using the invention, it is possible to transfer the drive power of the drive motor to the gear unit using the planetary gear units in an economically acceptable manner at a cost reduction of the rotary parking, which is reflected in achieving a justified price that will enable greater use of these systems in the future.
