Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing:
[0030] Such as figure 1 As shown, an electromagnetic eddy current braking device used for braking high-speed vehicles, the electromagnetic eddy current braking device is composed of an excitation unit 100 , a housing device 200 and a rotor device 300 . The casing device 200 wraps the entire brake device, the rotor device 300 is located inside the casing device 200, the three rotors are respectively located at the front and rear ends and the middle part of the casing, and two excitation units 100 are respectively arranged in the middle of the three rotor cooling fins. Through the rotation of the rotor, the effect of external air cooling and internal water cooling is achieved, which greatly improves the heat dissipation performance of the excitation disk. The housing device 200 and the rotor device 300 are connected and matched through bearings to form a whole.

The invention discloses an electromagnetic eddy current braking device for high-speed vehicle braking, and belongs to the technical field of high-speed vehicle braking. The device is composed of an excitation unit, a shell device and a rotor device. According to the invention, the device is novel in structure and clear in working principle; the excitation unit is used for providing stable and reliable braking force, most of heat generated on a excitation winding is directly discharged through a water cooling system, and a small part of heat is discharged out of a brake through an air cooling system; an air channel opening is formed in the edge of the excitation unit, so that an air flow path is longest, and heat dissipation is sufficient; the shell is of a rotary structure, and a pluralityof heat dissipation ribs are additionally arranged on the shell to facilitate discharging of internal heat; The cooling fins of the rotor heat dissipation structure are integrated with the rotor, andeddy heat generated by the rotor heat dissipation structure is dissipated through rib plates; And the edges of the rib plates are designed to be of fan blade structures, the rotor cooling fins rotateduring braking, and the fan blade structures on the edges push air to enable cold air to enter the brake, so that air flow passes through, and the fan blade structures rotate to push the air flow soas to enhance the air-cooling heat dissipation effect.
Description
technical field [0001] The invention belongs to the technical field of high-speed vehicle braking, and relates to an electromagnetic eddy current braking device, in particular to an electromagnetic eddy current braking device for high-speed vehicle braking. Background technique [0002] With the continuous development of modernization, vehicles have become a necessity in people's lives. People enjoy the convenience brought by vehicles and the comfort brought by technology to life. However, in the process of driving a vehicle, while experiencing speed and passion, people are also faced with sudden and potential hidden dangers, threatening the life and property safety of drivers and passengers. In order to make high-speed vehicles have good braking in a short period of time, it is an important content in the research of braking technology to minimize the damage of vehicle parts caused by braking. At present, electromagnetic eddy current technology has entered the vehicle brak...
