Abstract

The invention relates to the field of new energy automobile braking, in particular to a downward pressing type emergency braking device for a new energy automobile and a braking method. The downward pressing type emergency braking device comprises a bottom plate, a motor top plate, a mounting plate, a servo motor, a rotating shaft and the like; the motor top plate is fixedly mounted on the rear side of the top face of the bottom plate, the mounting plate is fixedly mounted in the middle of the bottom plate, the servo motor is fixedly mounted on the rear side of the top face of the bottom plate and located below the motor top plate, and the rotating shaft is arranged in the servo motor. Through cooperation of the first-stage friction deceleration ring and the second-stage friction deceleration ring, the first-stage friction deceleration ring and the second-stage friction deceleration ring are in contact with the fixed rotating disc to play a role in deceleration and braking, so that the fixed rotating disc and the rotating shaft are decelerated and stopped, meanwhile, the rotating shaft can be prevented from being abraded, and the service life of the servo motor is prolonged.

Description

technical field [0001] The invention relates to the field of braking of new energy vehicles, in particular to a push-down emergency braking device and a braking method for new energy vehicles. Background technique [0002] With the continuous development of new energy vehicles, more and more attention has been paid to environmentally friendly electric vehicles driven by electricity, which has led to the rapid development of new energy vehicles. New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, and brakes The system is an indispensable configuration of modern vehicles. The car braking system refers to a series of special devices that exert a certain force on certain parts of the car and perform a certain degree of mandatory braking to make the moving car According to the driver's request, the function of forced deceleration or even parking is performed. [0003] Existing brake systems usually use brake pads as brake components, and...
