When driver steps on brake pedal 31, the braking instruction of brake pedal 31 passes sequentially through first transfer gear the 32, second transfer gear 33, the two-sided rack slide block 36 passes to brake coordination gear 34, and then drive piston 24 to move, so that producing hydraulic pressure in master cylinder 23, complete skidding；Simultaneously, auxiliary switch is opened, wheel drive motors M is produced brake force and by charging circuit, accumulator E is charged, charging current produces magnetic field when solenoid 46, making iron core 44 overcome the elastic force of compression spring 47 to move right, iron core 44 drives single-side rack slide block 42 to move right by connecting rod 43 so that brake coordination gear 34 rotates backward, brake coordination gear 34 rotates backward drive piston 24 and moves right, thus the hydraulic pressure reduced in master cylinder 23 (brake fluid pressure).
When driver steps on brake pedal 31, the brake force of vehicle is consequently exerted at making a concerted effort of the brake force of the brake force (hydraulic braking force that hydraulic brake mechanism 2 produces) on wheel hub 1 and wheel drive motors M generation；When speed is more fast, the stalling current then produced in wheel drive motors M is more big, motor braking power is more big, and the suction that solenoid 46 produces is more big, and the displacement that iron core 44 moves is more big, oil pressure in master cylinder 23 is more little, hydraulic braking force is more little, thus when automobile high-speed is braked, increasing motor braking power, reducing by the conventional friction brake force of hydraulic braking, thus reducing the abrasion of friction plate in conventional brake, improve the wheel drive motors M response rate to braking energy simultaneously.
Optionally, in electric automobile during traveling, if brake coordination assembly 4 breaks down or accumulator E is in full power state, wheel drive motors M cannot to accumulator E charging and/or generation brake force, now electric automobile is adopted conventional hydraulic mode of braking to brake by hydraulic brake mechanism 2, it is ensured that traffic safety.
Following table is the braking electric energy recovering system used for electric vehicle of conventional hydraulic mode of braking and present invention braking distance test result under each speed.
From this table, the braking effect that the braking electric energy recovering system used for electric vehicle of the present invention produces with conventional hydraulic mode of braking is essentially identical, therefore, present invention achieves when the braking both ensureing make a concerted effort to meet automobile brake require, the response rate of braking energy in braking procedure can be improved and can reduce again the loss of conventional brake friction plate.

Wherein, charging capacitor C can adopt some bulky capacitor parallel connections to realize, owing to electric capacity charging response speed is faster than accumulator, so often causing the electric current that braking produces to have little time to be charged accumulator E namely disappearing, therefore, charge efficiency is very low, in order to overcome this technical problem, can effectively be avoided the waste of energy of braking generation by quick charge capacitor, improve charge efficiency.
