Abstract

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.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to an energy-feeding shock absorber. Background technique [0002] Existing shock absorbers used on heavy engineering vehicles, when the road conditions are uneven during transportation, frequent and violent relative motions occur between the frame and the axle, and the energy generated by the vibration is dissipated as waste heat, resulting in unnecessary energy loss. Contents of the invention [0003] The invention provides an energy-feeding shock absorber. [0004] The present invention is composed of a dust cover, a cylinder, a combined piston, a piston rod, a single clevis, an airbag, an airbag protective cover, an end cover, an accumulator, a first high-pressure oil pipe, a second high-pressure oil pipe and a high-pressure air pipe. The dust cover is provided with a round hole; the cylinder is provided with a single clevis and a round hole; the combined piston is composed of...
