The invention relates to a rigidity feedback device for servo force of an automobile electronic intelligent booster, and belongs to the field of automobile braking. The rigidity feedback device comprises a valve body and a protective ring, a rigid arm is installed in the valve body and is supported by a conical spring to keep horizontal and static, the conical spring is installed on a valve body seat, a main cylinder push rod is guided by the protective ring, and a main cylinder push rod seat is embedded into a groove of the valve body and is pressed on the rigid arm through an elastic check ring. The rigidity feedback device has the advantages of being novel in structure, providing servo force, being capable of being installed on an existing intelligent electronic booster, remarkably improving response characteristics of the electronic booster, improving reliability of a system under different working conditions, and prolonging service life of the system.
Description
technical field [0001] The invention relates to a feedback device used in the field of automobile braking, in particular to the improvement of an automobile electronic intelligent booster. Background technique [0002] Electronic smart boosters used in braking systems use electric motors to amplify the input force applied to the brake pedal. An operating device for pressure building of a brake master cylinder of a motor vehicle, comprising a front and rear housing arranged between the brake master cylinder and a brake pedal, and an internal rigid feedback device for a servo force for building pressure of the brake master cylinder , It also includes an electric motor, a guide device, and a transmission device. In summary, the torsional motion of the motor is converted into the translational motion of the piston through the above mechanisms. [0003] When the existing electronic booster works, the input force on the pedal is transmitted to the piston of the brake master cylin...
