[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Automobile brake hub brake pad wind cooling device, including temperature sensor 2, opening and closing module 3, controller 6;

[0027] The opening and closing module 3 includes a mounting seat 32, the mounting seat 32 is fixedly connected to the outer side of the torsion beam 5 of the vehicle, the two sides of the mounting seat 32 are respectively fixedly connected to the housings of the symmetrical electric push rods 312, the telescopic rods of the two electric push rods 312 are respectively fixedly connected to the corresponding connecting blocks 311, the two connecting blocks 311 are respectively connected to the corresponding pair of connecting rods 310 through a pin hinge, one end of the corresponding pair of connecting rods 310 is respectively connected to the corresponding connecting rod 37 through a pin hinge, the corresponding pair of connecting rods 37 is respectively fixedly connected to the corresponding shielding plates 38, and the two side ends of the two shielding plates 38 are respectively fixedly connected to the corresponding circular shafts 39;

A symmetrical outlet 31 is provided on one side of the mounting seat 32. The edges of the two outlets 31 are fixedly connected to the opening edges of one end of the corresponding trumpet-shaped shells 34, and the opening edges of the other ends of the two trumpet-shaped shells 34 are fixedly connected to the corresponding cylinders 35. The cross-sectional area of ​​the two trumpet-shaped shells 34 is larger than the cross-sectional area of ​​the two cylinders 35, and the outlet directions of the two cylinders 35 are close to the brake pads 1 of the vehicle.

[0029] One side of the mounting base 32 is fixedly connected to the controller 6 .

[0030] The temperature sensor 2 is fixedly connected to one side of the torsion beam 5 of the vehicle.

[0031] The shaft 4 is movably mounted in a torsion beam 5 of the vehicle.

[0034] Working principle: The mounting base 32 is fixedly mounted on the torsion beam 5 of the vehicle, with the opening 33 facing the forward direction of the vehicle. When the vehicle is driving, the temperature sensor 2 senses that the temperature of the brake pad 1 is too high, and a signal is fed back to the controller 6, so that the controller 6 controls the electric push rod 312 to start, and the telescopic rods of the two electric push rods 312 extend to drive the corresponding connecting blocks 311 to move respectively, and the two connecting blocks 311 drive the corresponding connecting rods 310 to swing respectively, and the corresponding pair of connecting rods 310 drive the corresponding shielding plates 38 to open, so that the opening 33 is exposed, as shown in FIG.

[0035] When the temperature sensor 2 senses that the temperature of the brake pad 1 remains stable, a signal is fed back to the controller 6, so that the controller 6 controls the telescopic rod of the electric push rod 312 to retract, so that the two shutters 38 are closed.

[0036] Beneficial effect: when the car is driving, when the temperature sensor 2 senses that the temperature of the brake pad 1 is too high, a signal is fed back to the controller 6, so that the controller 6 controls the electric push rod 312 to start, and the opening 33 is exposed through the opening and closing module 3. At this time, when the vehicle is driving, the high-speed airflow enters the mounting seat 32, the outlet 31, the trumpet-shaped shell 34, the cylinder 35, and finally blows to the brake pad 1 through the opening 33, and the brake pad 1 is cooled by the wind. The cross-sectional area of ​​the trumpet-shaped shell 34 is larger than the cross-sectional area of ​​the cylinder 35, which is conducive to the increase of wind speed, so that the brake pad 1 is cooled by the high-speed airflow during driving and maintained at a balanced temperature, thereby increasing driving safety.
