Problems solved by technology

[0002] With the increasing popularity of automobiles, driving speed increases, energy saving and consumption reduction, driving safety is the top priority. Currently, hybrid, pure electric vehicles and ordinary diesel / gasoline vehicles mainly use two methods of braking devices-disc brakes and drum brakes. These two types of brakes are driven by hydraulic pressure or air pressure to press the friction pad against the rotor. Due to the compressibility of liquid / gas, the response lags and the response time is long (solenoid valve response time + hydraulic pressure / pneumatic pressure response time + Brake device reaction time), braking energy efficiency is low, of the two methods, devices such as a booster that amplifies the operating force applied to the brake pedal and a master cylinder that converts the operating force amplified by the booster into hydraulic pressure are required etc., which complicates the construction of the device

Abstract

The invention provides an electronically-controlled electric brake caliper assembly and relates to the field of vehicle chassises. The electronically-controlled electric brake caliper assembly comprises a brake caliper body, a friction plate, a first piston, a driving nut, a planetary gear mechanism and a motor stator; the driving nut is fixedly mounted in the first piston; the first piston is fixedly arranged in the brake caliper body; and the motor stator drives the planetary gear mechanism and drives the first piston by a driving screw to push the friction plate to realize wheel brake. The electronically-controlled electric brake caliper assembly is capable of reducing energy transfer paths, high in response speed and also capable of performing emergency brake for a whole vehicle during power failure of the whole vehicle.
