Abstract

An active automobile turn gravity change control apparatus installs an elevating mechanism between each of four wheels and an automobile body of an automobile, and the elevating mechanism is driven by a motive power supply element and controlled by a controller to adjust the relative distance between each of the four wheels and the automobile body, so that when the automobile makes a turn, the controller detects the turning direction and speed of the automobile to actively adjust the elevating mechanism to change the inclining direction and extent of the automobile body and shift the center of gravity of the automobile towards the internal side of the curve of turning, so as to resist the inertia force produced by a turn of the automobile, achieve a safe and quick turn, and prevent a car overturn accident.

Claims

1. An active automobile turn gravity change control apparatus, which is applied to an automobile, comprising:

an elevating mechanism, disposed between a wheel and an automobile body of said automobile;

a motive power supply element, for driving said elevating mechanism to move vertically up and down, so as to change the height of a wheel suspension system of said automobile;

a controller, coupled to said motive power supply element for controlling said motive power supply element according to the turning direction and speed of said automobile to ascend or descend said elevating mechanism.

2. The active automobile turn gravity change control apparatus of claim 1, wherein said elevating mechanism includes a pneumatic cylinder and a pneumatic push rod, and said motive power supply element includes an air pressure source, a pressure gauge, an incoming air solenoid valve, an outgoing air solenoid valve, an incoming air speed adjusting valve and an outgoing air speed adjusting valve, and said pneumatic push rod is slidably installed in said pneumatic cylinder, and said air pressure source uses an incoming air pipe to interconnect said pneumatic cylinder, and said incoming air pipe includes said incoming air solenoid valve, said incoming air speed adjusting valve and said pressure gauge, and said pneumatic cylinder has an outgoing air pipe interconnected to the outside, and said outgoing air pipe installs said outgoing air solenoid valve and said outgoing air speed adjusting valve.

3. The active automobile turn gravity change control apparatus of claim 1, wherein said elevating mechanism includes a hydraulic cylinder and a hydraulic push rod, and said motive power supply element includes a hydraulic pump, a hydraulic tank and an oil relief valve, and said hydraulic push rod is slidably installed in said hydraulic cylinder, and said hydraulic tank includes an incoming oil pipe interconnected with said hydraulic cylinder, and said incoming oil pipe installs said hydraulic pump, and said hydraulic tank includes an outgoing oil pipe interconnected with said hydraulic cylinder, and said outgoing oil pipe installs said oil relief valve.

4. The active automobile turn gravity change control apparatus of claim 1, wherein said elevating mechanism includes a screw rod and a screw gear, and said motive power supply element includes a servomotor and a gear, and said screw rod is engaged with said screw gear, and said servomotor and said gear are coupled for synchronous rotations, and said gear is engaged with said screw gear and driven by said servomotor to rotate.

5. The active automobile turn gravity change control apparatus of claim 1, wherein said elevating mechanism and said motive power supply element come with four pieces each, and an elevating mechanism is installed between each of the four wheels and said automobile body of said automobile, and said controller controls the movements of said four elevating mechanisms according to the turning direction and speed of said automobile, so as to adjust the inclining direction and extent of said automobile body of said automobile.
