When a driver needs to shift gears and accelerate, the automobile driving mechanism can control the pushing plate 34 and the device on the pushing plate to move downwards, the piston plate 32 can extrude hydraulic oil in the liquid storage pipe 31, the hydraulic oil pushes the movable disc 36 and the device on the movable disc to move towards the direction close to the second 73 transmission shell plate, so that the conical sleeve 42 pushes the guide wheel 79 and the toothed rack 77 to move towards the direction close to the outer ring of the guide disc 76, the left side of the chain 713 is unfolded, the chain 713 can push the toothed rod 711 to move towards the direction close to the power output shaft 710, the toothed rack 77 drives the toothed rod 711 and the device on the toothed rod 711 to rotate faster through the chain 713, the rotating speed of the power transmission shaft 83 is increased, and the purpose of shifting gears of an automobile is achieved. When a driver needs to decelerate the automobile, the automobile driving mechanism controls the pushing plate 34 and the devices on the pushing plate to move upwards, the compressed return spring 37 resets to drive the movable plate 36 and the devices on the movable plate to move towards the direction far away from the second 73 of the transmission shell plate, the conical sleeve 42 is separated from the guide wheel 79, the compressed first compression spring 78 resets to drive the toothed rack 77 and the guide wheel 79 to move and reset towards the direction far away from the outer ring of the guide wheel 76, the compressed second compression spring 712 resets to drive the toothed rod 711 to move and reset towards the direction far away from the power output shaft 710, and the toothed rack 77 drives the toothed rod 711 and the devices on the toothed rack to decelerate through the chain 713, so that the driver can change different gears according to requirements.

During the shifting process of the driver, the distance sensor 63 can sense the position change of the driver, the distance sensor 63 can control the electromagnet 62 to be electrified, the electromagnet 62 is electrified to generate magnetism to adsorb the permanent magnet plate 59, so that the permanent magnet plate 59 drives the sliding rod 58 and the slotted liquid guide bar 57 to move in the direction away from the thick-layer valve plate 1, so that the slotted liquid guide strip 57 blocks the upper part of the h-shaped cavity 51, the cooling lubricating oil in the h-shaped cavity 51 cannot be conveyed into a space formed by the first transmission shell plate 71, the annular frame 72 and the second transmission shell plate 73, the cooling lubricating oil in the h-shaped cavity 51 flows back into the oil cooling storage tank car through the third pipe 56 with the one-way valve, the cooling lubricating oil in the space formed by the first transmission shell plate 71, the annular frame 72 and the second transmission shell plate 73 can not flow, so that the gear shifting can be ensured to be smooth and stable, and the jerking feeling brought to a driver by gear shifting can be reduced.

When the distance sensor 63 senses that the position of the distance sensor does not change any more, the distance sensor 63 controls the electromagnet 62 to be powered off, the electromagnet 62 does not adsorb the permanent magnet plate 59 any more, the stretched return spring 510 is reset to drive the permanent magnet plate 59 and the device on the permanent magnet plate to move towards the direction close to the thick-layer valve plate 1, so that the slotted liquid guide bar 57 does not block the upper part of the h-shaped cavity 51 any more, cooling lubricating oil in the h-shaped cavity 51 can enter a space formed by the first transmission shell plate 71, the annular frame 72 and the second transmission shell plate 73 through the slotted liquid guide bar 57 and the second tube 55 with the one-way valve, and the cooling lubricating oil circularly flows to cool and lubricate the internal transmission component 7.
