The present application relates to the field of new energy engineering vehicles, and discloses an emergency steering pump module, a power-assisted steering system, and a new energy engineering vehicle. The emergency steering pump module comprises a high-speed pump, a high-speed motor, and a power battery, wherein the high-speed motor is drivingly connected to the high-speed pump, and the power battery is electrically connected to the high-speed motor. The emergency steering pump module of the present application can be applied to a power-assisted steering system, and can replace a conventional steering oil pump to supply oil to an assisting oil cylinder when the conventional steering oil pump fails, the emergency steering pump module can operate independently without being driven by an engine, and therefore, the spatial limitation that traditional emergency steering pumps necessarily take off power from mechanical power sources such as a transfer case power take-off port or an engine power take-off port is eliminated; and the emergency steering pump module can be flexibly arranged at a proper position, and therefore, the arrangement of the power-assisted steering system is effectively simplified. In addition, the high-speed pump and the high-speed motor have relatively small sizes, enabling the emergency steering pump module to have a compact overall structure and a small footprint.
