In addition, by adjusting the hydrogen inside the air bag body 5, the hydrogen density is smaller than air, and then the hydrogen has a certain air buoyancy, and because the adjusting air bag body 5 is wrapped outside the conductor 6, so that the adjusting air bag body 5 has a supporting force for the conductor 6, and also has an air buoyancy, because of the relative offset of the force, and further the pressure caused by the conductor 6 and the movable brake block 7 to the inner side wall of the wheel cylinder 1 can be reduced under the influence of the air buoyancy inside the adjusting air bag body 5, if the downward pressure of the conductor 6 and the movable brake block 7 to the wheel cylinder 1 becomes small, when the oil inside the wheel cylinder 1 pushes the piston body 3 forward, the resistance received by the oil can be reduced along with the reduction of the downward pressure, so that after a driver steps on the brake pedal, the oil is filled into the wheel cylinder 1 through the oil pipe 2, and generates oil pressure to the piston body 3, the pushing action of the oil pressure can be more quickly worked, the movable brake block 7 can quickly reach the surface of the brake disc 8 in a shorter time, the brake disc 8 is tightly attached to the movable brake block 7, and the effective brake efficiency is improved, and the brake efficiency of the driver can be better.

Referring to fig. 2-4, the shape of the movable brake pad 7 is a cylinder with a concave shape, the size of the protruding edge end of the movable brake pad 7 is matched with the size of the inward concave shape of the heat sink 4, the outer surfaces of the upper and lower ends of the movable brake pad 7 are provided with sliders, the side wall surface of the heat sink 4 contacting the outer wall of the movable brake pad 7 is provided with a channel matched with the slider arranged on the outer surface of the movable brake pad 7, and the position of one end of the movable brake pad 7 facing the brake disc 8 exceeds the position of one end of the heat sink 4 facing the brake disc 8.
The using method of the invention has the following working principle:
when the vehicle meets an emergency, a driver immediately steps on a brake pedal, a push rod further pushes a piston in a main cylinder forwards through the brake pedal, the piston is extruded through the piston, oil in the main cylinder flows into a guide pipe, the oil flows into the interior of a wheel cylinder 1 through an oil guide pipe 2 in a large amount, the oil fills the inner cavity of the wheel cylinder 1, so that oil pressure is generated on a piston body 3 in the inner cavity of the wheel cylinder 1, the piston body 3 is pushed forwards under the action of the oil pressure, when the piston body 3 moves forwards, a heat radiation body 4, an adjusting air bag body 5, a conductor 6 and a movable brake block 7 move forwards along with the movement of the piston body 3, the movable brake block 7 starts to gradually approach one side of a brake disc 8, the fixed brake block 9 and a fixed clamp plate 10 are fixed, the movable brake block 7 approaches the brake disc 8, the brake disc 8 gradually fixes one end surface of the brake block 9 until the movable brake block 7 and the brake disc 8 completely adhere to each other, the brake disc 8 and the brake block 8 starts to gradually rotate until the brake disc 8 starts to be pressed, and the vehicle can gradually rotate.
When the movable brake block 7 compresses the brake disc 8 for braking, because the movable brake block 7 and the brake disc 8 are mutually extruded, strong friction can be generated between the movable brake block 7 and the brake disc 8, thereby causing the surface of the movable brake block 7 to generate a large amount of heat energy, at the moment, because the vehicle still runs forwards, the external air still can form air flow to flow backwards, when the external air flow rushes to the movable brake block 7, the external air flow can flow into the inner cavity at one side of the radiator 4 through the air vent 11 at the windward side in a large amount, the inflowing air flow uniformly flows through the surfaces at the two sides of the movable brake block 7 and the outer surface of the adjusting air bag body 5 along the track of the inner cavity of the radiator 4, the cooling and heat dissipation effects are implemented on the movable brake block 7 and the adjusting air bag body 5, because the adjusting air bag body 5 is wrapped outside the conductor 6, and the conductor 6 is just opposite to the center of the movable brake block 7, further, the heat energy at the center of the adjusting air bag body 5 is from the conduction effect of the conductor 6 on the heat energy at the center of the movable brake block 7, but the cooling effect can be continuously influenced by the air flow cooling by cold conduction, the effective cooling effect, and the effective cooling effect of the movable brake block 7 can be timely, and the brake block 7 can be obtained, and the overall cooling efficiency can be obtained, and the brake block 7 can be unified.
If the vehicle meets emergency, but when 8 rotational speeds of brake disc are too fast, the bulk temperature of activity brake pads 7 is higher this moment, adjust 5 inside gases of gasbag body and receive the influence of hot temperature and expand, and then extrude the inboard of activity brake pads 7 forward, make activity brake pads 7 forward movement, implement the suppression of hugging closely more to brake disc 8, thereby effectual autonomic reinforcing activity brake pads 7's braking dynamics, guarantee the braking effect of activity brake pads 7, make the brake disc 8 stall that can be very fast, avoid the vehicle to take place the striking accident.
In addition, because of adjusting the inside hydrogen effect of gasbag body 5, and then make conductor 6 and activity brake block 7 together diminish to the pressure that the inside wall of wheel cylinder 1 caused, if conductor 6 and activity brake block 7 diminish to the holding down force of wheel cylinder 1, then the inside fluid of wheel cylinder 1 is when promoting the piston body 3 removal forward, the resistance that fluid receives can reduce along with the holding down force diminishes, thereby after the driver is stepping on brake pedal, fluid pours into the inside of wheel cylinder 1 through oil pipe 2, and to piston body 3 production oil pressure, the impetus of oil pressure can be more quick to be played, make activity brake block 7 can be in shorter time, reach the surface of brake disc 8 fast, reach braking effect.
