Referring to fig. 1, a driving system of a flying vehicle according to a first embodiment of the present invention is shown, including: a drive 10, a first control mechanism 20, a propeller 30, a second control mechanism 40, and wheels 50.
Wherein: the driving system of the flying automobile comprises a driver 10, two output shafts 11 extend out of two ends of the driver 10 respectively, a propeller 30 which is provided with a first control mechanism 20 and connected with the first control mechanism 20 is arranged on one output shaft 11, a wheel 50 which is provided with a second control mechanism 40 and connected with the second control mechanism 40 is arranged on the other output shaft 11, the first control mechanism 20 is used for lifting output power of the driver 10 and transmitting the output power to the propeller 30, and the second control mechanism 40 is used for reducing the output power of the driver 10 and transmitting the output power to the wheel 50.

In the present embodiment, in order to boost the output power of the driver 10 on the one hand; on the other hand, in order to reduce the output power of the driver 10, one end of the driver 10 is connected with a first control mechanism 20 through an output shaft 11, and the first control mechanism 20 is connected with a propeller 30; the second control mechanism 40 is connected to the other end of the output shaft 11, and the second control mechanism 40 is connected to the wheel 50. in use, the first control mechanism 20 is used for raising the output power of the driver 10 and transmitting the output power to the propeller 30, and the second control mechanism 40 is used for reducing the output power of the driver 10 and transmitting the output power to the wheel 50.
In the present embodiment, as shown in fig. 1, it should be noted that the first control mechanism 20 includes a first planetary gear assembly 21 disposed on the output shaft 11 and a first clutch 22 disposed on a side of the first planetary gear assembly 21 away from the driver 10, wherein the first planetary gear assembly 21 is used for lifting the output power of the output shaft 11, and the first clutch 22 is used for transmitting the output power lifted by the first planetary gear assembly 21 to the propeller 30. Specifically, the first planetary gear assembly 21 includes a first ring gear 211 disposed on the output shaft 11, a first sun gear 212 disposed on the output shaft 11, a first planet gear 213 engaged with the first sun gear 212, and a first carrier 214 connecting the first planet gear 213 and the first clutch 22, and the first planet gear 213 is engaged with the first ring gear 211. In this embodiment, it should be noted that a connecting bolt 31 is disposed at one end of the propeller 30, a reverse thread is disposed on the connecting bolt 31 to ensure that the propeller 30 does not loosen during continuous high-speed operation, the propeller 30 is fixed on the first ring gear 211 by the connecting bolt 31 to connect the propeller 30 with the first control mechanism 20, and the propeller 30 is made of a light high-strength material with small moment of inertia.
In this embodiment, it can be understood that, when the hovercar driving system uses the flight mode, it is necessary to transmit the power of the driver 10 to the direction of the propeller 30, and to disconnect the power transmission process of the driver 10 to the direction of the wheels 50, specifically, to connect the first clutch 22 and disconnect the second clutch 42, at this time, the output power of the driver 10 is transmitted to the first sun gear 212 through the output shaft 11, the first sun gear 212 transmits the output power to the first planet gear 213, the first planet gear 213 transmits the output power to the first ring gear 211, since the number of teeth of the first planet gear 213 is smaller than that of the first ring gear 211, the transmission of the output power from the first sun gear 212 to the first ring gear 211 is a process of increasing the speed and decreasing the torque, and since the propeller 30 is fixed to the first ring gear 211 through the connecting bolt 31, the first ring gear 211 can drive the propeller 30 to rotate at a high speed to drive the hovercar, since the second clutch 42 is in the disconnected state at this time, the second sun gear 412, the second planet gears 413 and the second ring gear 411 are all in the free state, so that the second sun gear 412 and the second planet gears 413 spin to avoid the movement of the wheels 50.
In the present embodiment, as shown in fig. 1, it should be noted that the second control mechanism 40 includes a second planetary gear assembly 41 disposed on the output shaft 11, and a second clutch 42 disposed on a side of the second planetary gear assembly 41 close to the driver 10, wherein the second planetary gear assembly 41 is used for reducing the output power of the output shaft 11, and the second clutch 42 is used for transmitting the reduced output power of the second planetary gear assembly 41 to the wheels 50.

In the present embodiment, it can be understood that when the hovercar drive system uses the wheeled drive mode, it is necessary to transmit the power of the driver 10 in the direction of the wheels 50 and to disconnect the progress of the power transmission of the driver 10 in the direction of the propeller 30. Specifically, the second clutch 42 is turned on, the first clutch 22 is turned off, at this time, the output power of the driver 10 is transmitted to the second sun gear 412 through the output shaft 11, the second sun gear 412 transmits the output power to the second planet gear 413, the second planet gear 413 transmits the output power to the second ring gear 411, because the number of teeth of the second ring gear 411 is greater than that of the second sun gear 412, the transmission of the output power from the second sun gear 412 to the second ring gear 411 is a speed reduction and torque increase process, and because the hub 70 and the brake disc 61 are both connected with the second ring gear 411 through a bolt, the output power of the driver 10 finally drives the wheel 50 to rotate, and the brake 62 provides the brake torque required by the brake disc 61, and because the first clutch 22 is in the star gear off state, the first planet gear 213, the first sun gear 212 and the first ring gear 211 are all in a free state, so that the first sun gear 212 and the first planetary gear 213 idle to prevent the propeller 30 from moving.
In the present embodiment, as shown in fig. 1, it should be noted that the driving system of the flying vehicle further includes a hydraulic oil pipe, and the hydraulic oil pipe is connected to the first clutch 22 and the second clutch 42 respectively. It will be appreciated that when it is desired to engage the first clutch 22 or the second clutch 42, high pressure oil is fed from the hydraulic oil line into the hydraulic cylinder, the hydraulic cylinder is pushed by the oil pressure to move to one side of the steel plates to compress the steel plates and the friction plates, and since the steel plates are connected to the body and the friction plates are connected to the first planet carrier 214 and the second planet carrier 414, the first planet carrier 214 or the second planet carrier 414 is locked to the body. When the first clutch 22 or the second clutch 42 needs to be disconnected, the hydraulic oil passage is depressurized, and the hydraulic oil passage does not apply pressure to the steel plates and the friction plates any more, so that the steel plates or the friction plates can rotate freely, and the first planet carrier 214 or the second planet carrier 414 is not locked.
In the present embodiment, as shown in fig. 1, it should be noted that a brake assembly 60 is further disposed on a side of the second planetary gear assembly 41 away from the driver 10, a hub 70 is disposed on a side of the brake assembly 60, and the hub 70 is connected to the wheel 50.
