The invention discloses a hydraulic electricity generation shock absorber of a vehicle, belonging to the technical field of vehicle suspension systems and hydraulic transmission. The hydraulic power generation shock absorber of the vehicle generates electricity by utilizing pressure generated by hydraulic oil during shock absorption and comprises a piston shock absorption part, a valve path part and an electricity generation part, wherein the piston shock absorption part comprises a hydraulic cylinder (1) and a piston (2); the electricity generation part comprises a hydraulic motor (13) and an electric generator (16); and the piston (2) is pushed to move up and down in the hydraulic cylinder (1) during the shock absorption of the vehicle so that the hydraulic oil inside the hydraulic cylinder (1) is extruded out of the outlet of an upper cavity or a lower cavity of the hydraulic cylinder (1) and passes through the valve path part and then pushes the hydraulic motor (13) to drive the electric generator (16) to generate the electricity. The invention makes the hydraulic shock absorber of the vehicle possible have both stable shock absorption and electricity generation performance by adopting a reliable and mature hydraulic transmission technology and also provides a new research direction for the developed hydraulic shock absorber.
