The principle of work of electronlmobil electric braking of the present invention and hydraulic braking coordinated control system is:
In electric automobile during traveling process, when chaufeur does not touch on the brake pedal 31, pilot switch (normally closed switch) closes, and will be shorted through magnet coil 46, and storage battery E supplies electric drive running car to wheel drive motors M; Now iron core 44 by Compress Spring 47 bullet to the side of hollow shell 45;
When chaufeur steps on brake pedal 31, the braking instruction of brake pedal 31 passes to brake coordination gear 34 by the first transfer gear 32, second transfer gear 33, the two-sided rack slide block 36 successively, and then drive piston 24 to move, to make to produce hydraulic pressure in master brake cylinder 23, complete drag; Simultaneously, pilot switch is opened, wheel drive motors M is produced braking force and is charged to storage battery E by charge circuit, charging current produces magnetic field when magnet coil 46, the elastic force making iron core 44 overcome Compress Spring 47 moves right, iron core 44 drives single-side rack slide block 42 to move right by pipe link 43, brake coordination gear 34 is rotated backward, brake coordination gear 34 rotates backward and drives piston 24 to move right, thus reduces the hydraulic pressure (brake fluid pressure) in master brake cylinder 23.
When chaufeur steps on brake pedal 31, the braking force of vehicle be applied to braking force that braking force on wheel hub 1 (hydraulic braking force that hydraulic brake mechanism 2 produces) and wheel drive motors M produce with joint efforts; When the speed of a motor vehicle is faster, the braking current then produced in wheel drive motors M is larger, motor braking power is larger, the suction that magnet coil 46 produces is larger, the displacement of iron core 44 movement is larger, oil pressure in master brake cylinder 23 is less, hydraulic braking force is less, thus when automobile high-speed is braked, increase motor braking power, reduce by the conventional friction braking force of hydraulic braking, thus the wearing and tearing of friction lining in reduction conventional brake, improve wheel drive motors M to the percent recovery of braking energy simultaneously.
Optionally, in electric automobile during traveling, if when brake coordination assembly 4 breaks down or storage battery E is in full power state, wheel drive motors M cannot charge to storage battery E and/or produce braking force, now electronlmobil adopts conventional hydraulic brake mode to brake by hydraulic brake mechanism 2, ensures traffic safety.
