The invention discloses an
energy feedback shock absorber which comprises a dust cover, a cylinder
barrel, a combined
piston, a
piston rod, a single lug ring, an air bag, an air bag protection cover, an end cover, an energy accumulator, a first high-pressure oil
pipe, a second high-pressure oil
pipe and a high-pressure air
pipe. By the aid of a combined
piston structure, a first curved throttling oil channel and a second curved throttling oil channel are formed, oil in an upper cavity of the cylinder
barrel passes the first curved throttling oil channel, a first
piston rod oil channel is connected with a hydraulic
system through the first high-pressure oil pipe, oil in a lower cavity of the cylinder
barrel passes the second curved throttling oil channel, a second
piston rod oil channel is connected with the hydraulic
system through the second high-pressure oil pipe, circulating pressure oil flow needed by power generation can be realized, the air bag arranged at the bottom of the cylinder barrel is communicated with the energy accumulator and timely generates elastic deformation, the size of the air bag is increased or decreased, and the
energy feedback shock absorber effectively solves the problem of unequal
volume change of the upper cavity and the lower cavity of the cylinder barrel when the piston slides.
