Embodiment Construction

[0028] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0029] Such as figure 1 As shown, the booster device of the present invention is composed of an input part 2, a displacement sensor 3, a pressure sensor 4, a connecting wire harness 5, a controller assembly 6, a direct drive motor 7, an actuator 8, an output part 9 and a housing assembly 10. . The input part 2 is connected with the brake pedal 1, and the input part 2 can rotate plus or minus 5 degrees relative to the axial direction of the booster device. One end of the displacement sensor 3 is fixed, and the other end is connected to the input part 2, and moves axially with the input part 2 synchronously. When the driver steps on the brake pedal 1, the displacement sensor 3 will collect the relative displacement of the input part 2, and then connect the wiring harness 5 transmits the ...

Description

technical field [0001] The invention relates to the field of automobile braking systems, in particular to an electric power booster for a braking system and an operating method thereof. Background technique [0002] Electric vehicles are the trend of automobile development. Compared with traditional gasoline engine vehicles, electric vehicles cannot provide the vacuum source required by the vacuum booster of the braking system, so it is necessary to develop a new booster to replace the original vacuum booster. At present, in the known technology, the technical materials similar to the technical effect of the present invention are: [0003] 1. CN200710111537.5 An electric power-assisted braking system. Its main structure is composed of a motor, a reduction mechanism, a transmission mechanism and a controller. The output shaft of the motor is connected to the input end of the reduction mechanism, and the output end of the reduction mechanism is connected to the transmission me...
