The invention provides a two-wheel-distributed drive electric vehicle braking energy recovery system based on stacked unidirectional valves and linear exhaust solenoid valves, and belongs to the technical field of electric vehicle braking energy recovery. According to the two-wheel-distributed drive electric vehicle braking energy recovery system, aiming at the characteristic that motor braking force of driving wheels of a two-wheel-distributed drive electric vehicle is independently adjustable, by additionally arranging parts such as a secondary gas storage tank, a switch solenoid valve, a three-way valve, the driving wheel stacked unidirectional valves, the driving wheel linear exhaust solenoid valves and driving wheel braking pressure sensors in an existing decoupling braking energy recovery system based on pneumatic ABS solenoid valves, driving wheel braking gas circuits are each of a double-loop structure, when braking energy is recovered, the two-wheel-distributed drive electricvehicle braking energy recovery system can select a gas source with the high gas pressure to provide high-pressure gas for driving wheel braking gas chambers, and thus the key problems that in the existing system, during continuous braking, the pressure of the gas source is slightly low, and consequently driving wheel coupling braking force is low in response speed and lags behind demanded brakingforce are effectively solved.
