The invention discloses a braking energy regeneration type electro-hydraulic hybrid driving system and an extensible chassis. The braking energy regeneration type electro-hydraulic hybrid driving system mainly comprises a novel braking energy-saving pump/motor, a supporting plate, a chassis base, a supporting frame and a hydraulic telescopic cylinder. A sliding block I and a sliding block II are installed between the chassis base and the supporting frame. A cylinder rod of the hydraulic telescopic cylinder is fixed to the cylinder body supporting frame through a plug pin and a cotter pin. The novel braking energy-saving pump/motor comprises a pump/motor body, a novel electromagnetic clutch and a motor body, the pump/motor body is connected to the right end of the novel electromagnetic clutch through a flat key I, the motor body is connected to the left end of the novel electromagnetic clutch through a flat key II, and a two-position two-way electromagnetic valve and an armature body are controlled to be powered on and powered off through a controller. Various recovery modes of braking energy are realized; when the whole vehicle needs extra torque, the motor serves as a motor and provides auxiliary power together with the energy accumulator. According to the technical scheme, the energy utilization efficiency of the braking system can be effectively improved, the application scene of the chassis can be improved, and practicability and economical efficiency are achieved.
