Hydraulic dual circuit brake system for motor vehicles has at least pump to generate vacuum for brake force intensifier, which is independent of vehicle engine

摘要

The system has a vacuum brake force intensifier (4) in each circuit, connected to a vacuum source (10). There is at least one vacuum generator, which is actuated independent of the vehicle engine, to generate a vacuum in each brake force intensifier independent of the other one. At least one generator is a pump with electric motor drive. The intensifiers actuate two brake cylinders (5), which are in fluidic connection via a pressure compensation element.
