The embodiment of the invention provides a shock absorber, a suspension system and a vehicle. The shock absorber comprises a cylinder body, a piston assembly and a bidirectional hydraulic pump, wherein the cylinder body comprises a cavity; the piston assembly is arranged along the cavity in a sliding mode and divides the cavity into a first cavity body and a second cavity body. A first oil way is arranged between the two-way hydraulic pump and the first cavity, and a second oil way is arranged between the two-way hydraulic pump and the second cavity; the bidirectional hydraulic pump has a first state and a second state; in the first state, oil in the first cavity sequentially passes through the first oil way, the two-way hydraulic pump and the second oil way to be injected into the second cavity. In a second state, the oil in the second cavity sequentially passes through the second oil way, the bidirectional hydraulic pump and the first oil way to be injected into the first cavity; through the arrangement of the two-way hydraulic pump, the movement speed of the shock absorber is effectively increased.
