Problems solved by technology

When a metal sheet (usually copper or copper-aluminum alloy) cuts the magnetic induction line, an eddy current will be generated inside the metal, which will generate a magnetic field to resist the movement, and the brake shoe is used to clamp the motor bearing to achieve braking. Due to the structural design The reason is that when braking, the friction of the brake shoes is used to brake, resulting in a large amount of heat, and the fan in the motor usually rotates according to the rotation of the motor shaft. When the motor bearing brakes, The cooling fan will stop rotating, which will cause a large amount of heat to accumulate and increase the temperature. However, there are many electrical appliances in the electronic brake assembly, and long-term high temperature will easily cause damage to electrical components. Therefore, we propose a new energy pure electric vehicle Dedicated electromagnetic brake assembly

Abstract

The invention discloses an electromagnetic brake assembly dedicated to new energy pure electric vehicles, which comprises an electromagnetic brake body, a mounting plate is fixed on the outside of the electromagnetic brake body, and a brake wheel is arranged inside the electromagnetic brake body, and a plurality of brake wheels are fixed at equal angles. The limit bar, heat dissipation mechanism, power storage mechanism and linkage components outside the inner connecting shaft of the brake wheel, the heat dissipation mechanism is installed outside the inner connecting shaft of the brake wheel, the power storage mechanism is installed outside the inner connecting shaft of the brake wheel, and connected with the heat dissipation mechanism, The linkage assembly used to adjust the position of the heat dissipation mechanism is installed on the mounting plate and docked with the heat dissipation mechanism. The invention realizes the function of providing a wind blowing heat dissipation to the outside of the brake wheel by installing the heat dissipation mechanism on the outside of the existing electromagnetic brake body. At the same time, with the action of the power storage mechanism, the heat dissipation mechanism can continue to work for a period of time during electromagnetic braking to discharge the heat generated by the friction of the brake, thereby avoiding a large amount of heat generated by friction.

Description

technical field [0001] The invention relates to the technical field of electromagnetic brakes, in particular to an electromagnetic brake assembly dedicated to new energy pure electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. [0003] Electromagnetic brakes are one or two strips of very strong neodymium magnets. When a metal sheet (usually copper or copper-aluminum alloy) cuts the magnetic induction line, an eddy current will be generated inside the metal, which will generate a magnetic field to resist the movement, and the brake shoe is used to clamp the motor bearing to achieve braking. Due to the structural design The reason is that when braking, the friction of the brake sho...
