The invention discloses a vacuum booster assembly which comprises a vacuum booster and a brake master cylinder connected with the vacuum booster. The vacuum booster is provided with an output force ejector rod, a vacuum shell and a boosting push rod which is inserted into the vacuum shell in a sliding manner; the vacuum booster is provided with a spring seat and a spring piece which are used for simulating brake pedal force, one end of the spring piece abuts against the vacuum shell, the other end of the spring piece is fixed to the spring seat, the spring piece is clamped between the vacuum shell and the spring seat, and the spring seat is fixed to the boosting push rod. The piston of the brake master cylinder is located in the vacuum cavity of the vacuum booster and located on the moving path of the output force ejector rod, and a gap is formed between the piston of the brake master cylinder and the vacuum booster. The invention further discloses an automobile braking energy recovery system, feedback torque of an engine can be fully utilized, and high braking energy recovery is supported, and the cruising ability of the automobile is improved. The invention belongs to the technical field of engines.
