[0039] Example 1
[0040] Such as Figure 1-Figure 2 As shown, the electric servo brake device with multiple working modes of the present invention includes a housing 2, an end cover 13, a brake master cylinder 1, a ball screw 12, a transmission mechanism, a pushing mechanism and a pedal mechanism, and a housing 2 It is connected with the end cover 13, and a cavity is formed between the housing 2 and the end cover 13, a ball screw 12 is installed in the center of the cavity, and the transmission mechanism is connected with the ball screw 12 for output torque drive system The master cylinder 1 is activated to achieve servo braking. The piston of the master cylinder 1 is installed in the housing 2. The piston is pushed in its braking direction by a pushing mechanism. The pushing mechanism is connected with the pedal mechanism. The pushing mechanism is used for transmission. The driving force of the pedal mechanism; the ball screw 12 includes a nut 23, a first bearing 32 and a seco...

[0046] Example 2
[0047] Using the electric servo brake device of the present invention in online control mode:
[0048] In the wire control mode, the gap between the inner annular end surface of the tray 5 and the front end surface of the auxiliary push rod 6 is S0, the pedal force will not be transmitted to the reaction disk 31, and the pedal force is all provided by the conical spring 15.
[0049] In online control mode, when the driver steps on the pedal, the pedal force of the pedal is transmitted to the conical spring 15 via the U-shaped hinge 20, and then the pedal is transmitted to the auxiliary push rod 6 under the action of the push rod 16; The required target braking force is generated by the feedback braking of the power motor of the automobile, and the target braking force depends on the pedal stroke (the pedal stroke is measured by the second sensor gear 14 and the second rotation angle sensor).
[0050] When the car's power battery is allowed to charge or the feedback ...

[0052] Example 3
[0053] The electric servo brake device of the present invention is used in the boost brake mode,
[0054] The inner annular end surface of the control tray 5 is aligned with the front end surface of the auxiliary push rod 6, so as to eliminate the gap S0 between the inner ring end surface of the tray 5 and the front end surface of the auxiliary push rod 6 to ensure that the reaction disk 31 reacts to the ball screw. The force of 12 and the putter becomes a fixed ratio. The first rotation angle sensor (non-contact rotation angle sensor) connected to the first sensor gear 9 is the lead screw stroke sensor for measuring the stroke of the ball screw 12. When the displacement difference between the control push rod 16 and the ball screw 12 is 0, the regenerative braking is withdrawn, and the braking force is all provided by the friction brake.
[0055] Among them, the braking deceleration is greater than 0.25g.
[0056] The reaction disk 31 is made of rubber material. ...
