Machine is recycled and is used, as document " decoupling type brake energy recovering system research " based on EMB (Yang Kun, Gao Song, Wang Jie,
Equal study [J] automobile engineering, 2016,38 (8): 1072-1079. based on the decoupling type brake energy recovering system of EMB) institute
It states, 30% or so of energy needed for this portion of energy can account for driving vehicle.
Currently, brake energy recovering system can be divided into manifold type and two kinds of decoupling type, manifold type braking according to working principle
Though energy recycling system without the arrangement of the former vehicle braking system of change, has, brake feel is poor, Brake energy recovery rate is low
Disadvantage, application gradually decreases at present.
Decoupling type brake energy recovering system can be driven by the coupling of mechanical braking force and motor braking power accurately to meet
The braking requirement for the person of sailing has the advantage that brake feel is good, Brake energy recovery rate is high.When motor braking power can be fully met
When operator brake demand, brake force is provided by motor braking completely, when motor braking power cannot fully meet operator brake
When demand, vehicle brake force is provided jointly by motor braking and mechanical braking, therefore the conjunction of motor braking power and mechanical braking force
The demand brake force that can power accurately track driver just becomes the key for influencing decoupling type Brake energy recovery effect.

The decoupling type brake energy recovering system of solenoid valve；This scheme has at low cost, the advantage of Yi Shixian, but finds under study for action
There are the following problems: the adjustment speed of brake chamber pressure depends on the difference of air accumulator gas pressure and brake chamber gas pressure
Value, when continuously braking number is greater than twice when driving, pressure can be substantially reduced, and continuously brake in air accumulator number
More, pressure decline is bigger, and the adjustment speed of brake chamber pressure can be substantially reduced at this time, and then make brake energy recovering system
The coupling brake force for being applied to vehicle can lag behind demand brake force, thus bring brake feel different from conventional braking system,
And it may cause the serious problems such as braking distance is elongated.

Relay valve (22) is discharged into atmosphere, to release the air-pressure brake power of right non-driving wheel (31).
The two drive electric vehicle brake powers based on stacked unidirectional valve and linear exhaust solenoid valve are recycled in gas circuits and are switched
Solenoid valve (5), right driving wheel stacked unidirectional valve (8), left driving wheel stacked unidirectional valve (19), right driving wheel linear rows pneumoelectric
Magnet valve (13), the linear exhaust solenoid valve of left driving wheel (14) work characteristics be described below.
When the non-brake pedal of driver (1), switch electromagnetic valve (5) is in an off state, the first triple valve (7)
Port a at without high pressure gas；When driver's brake pedal (1) but when not triggering braking energy recovering function, switch electricity
Magnet valve (5) is in an off state, without high pressure gas at the port a of the first triple valve (7)；When driver's brake pedal (1)
And when triggering braking energy recovering function, switch electromagnetic valve (5) is in the conductive state, has height at the port a of the first triple valve (7)
It calms the anger body.
There are three ports for right driving wheel stacked unidirectional valve (8) tool: air inlet port a, air inlet port b and air outlet c, gas
Body can only be flowed into from the air inlet port a and air inlet port b of right driving wheel stacked unidirectional valve (8), from right driving wheel superposing type list
It is flowed out to the air outlet c of valve (8), so that controlling gas can only flow to from the first triple valve (7) or drive shaft relay valve (21)
Right driving wheel brake chamber (11), cannot reversely be connected；When the air pressure of air inlet port a is greater than the air pressure of air inlet port b, end
Mouth a and port c conducting, port b shutdown；When the air pressure of air inlet port a is less than the air pressure of air inlet port b, port b and port c
Conducting, port a shutdown.
There are three ports for left driving wheel stacked unidirectional valve (19) tool: air inlet port a, air inlet port b and air outlet c,
Gas can only be flowed into from the air inlet port a and air inlet port b of left driving wheel stacked unidirectional valve (19), from left driving wheel superposing type
The air outlet c of check valve (19) flows out, so that controlling gas can only be from the first triple valve (7) or drive shaft relay valve (21)
Left driving wheel brake chamber (18) are flowed to, cannot be reversely connected；When the air pressure of air inlet port a is greater than the air pressure of air inlet port b
When, port a and port c conducting, port b are turned off；When the air pressure of air inlet port a be less than air inlet port b air pressure when, port b and
Port c conducting, port a shutdown.
There are three ports for the linear exhaust solenoid valve of right driving wheel (13) tool: port a, port b and exhaust port c, port a
It is connected with port b with braking gas circuit, is in normal open state, exhaust port c is not connected with braking gas circuit, steps on stepping on deceleration of electrons
When plate (1), exhaust port c is in close state, and is not connected with atmosphere；When unclamping electronic brake pedal (1), exhaust port c
It is in the open state, it is connected with atmosphere, aperture relationship proportional to the pedal displacement of electronic brake pedal (1).
There are three ports for the linear exhaust solenoid valve of left driving wheel (14) tool: port a, port b and exhaust port c, port a
It is connected with port b with braking gas circuit, is in normal open state, exhaust port c is not connected with braking gas circuit, steps on stepping on deceleration of electrons
When plate (1), exhaust port c is in close state, and is not connected with atmosphere；When unclamping electronic brake pedal (1), exhaust port c
It is in the open state, it is connected with atmosphere, aperture relationship proportional to the pedal displacement of electronic brake pedal (1).
By above-mentioned discussion it is found that passing through air accumulator (3) secondary in driving wheel braking gas circuit, switch electromagnetic valve (5), first
Triple valve (7), right driving wheel stacked unidirectional valve (8), the linear exhaust solenoid valve of right driving wheel (13), left driving wheel are linearly vented
The components such as solenoid valve (14), left driving wheel stacked unidirectional valve (19), the second triple valve (20) and drive shaft relay valve (21),
So that each driving wheel braking gas circuit is all had two independent high-pressure air sources and double back line structure, is stepped on when driver steps on deceleration of electrons
When plate (1) and no triggering braking energy recovering function, high pressure gas needed for left driving wheel (17) and right driving wheel (10) is by leading
Air accumulator (4) provides；When driver steps on electronic brake pedal (1) and triggering braking energy recovering function, left driving wheel
(17) it is provided with high pressure gas needed for right driving wheel (10) by the big person of air pressure in main air accumulator (4) and secondary air accumulator (3), thus
When effectively can solve continuously to brake present in existing scheme, because of the relatively low bring driving wheel coupling braking force-responsive of bleed pressure
Speed is slow, and lags behind the critical issue of demand brake force.
