Description
Technical field
The invention belongs to automobile brake field, specifically, is about the electric power brake pedal structure of one.
Background technology
At present automobile brake pedal all adopts pure mechanical system, self non helping hand function, and treadle effort is heavy, therefore need additionally to increase vacuum booster and carry out power-assisted, assist rate is subject to engine limitations, is difficult to further raising, also has in addition the defect large, speed of response is low that takes up room.Therefore, be necessary to provide a kind of electric power brake pedal structure to overcome above-mentioned defect.
Summary of the invention
Object of the present invention is just to provide a kind of electric power brake pedal structure, carries out power-assisted and causes that assist rate is restricted, the problem large, speed of response is low takes up room to solve available technology adopting vacuum booster.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of electric power brake pedal structure, comprising:
Brake-pedal support;
Brake pedal, described brake pedal inside is provided with pressure sensor;
Drive motor, described drive motor is fixed on described brake-pedal support by drive motor support;
Brake pedal arm, described brake pedal arm one end is set to tooth fan structure, and the other end is connected with brake pedal, is welded as a whole with sleeve pipe, rotates centered by can winding being placed in the bolt of rear end plate on drive motor support;
Driven wheel, the drive motor output shaft fixed connection on described driven wheel and described drive motor is integrated, and engages with the tooth fan structure on described brake pedal arm;
Pull back spring, described pull back spring is arranged between described brake pedal arm and described drive motor support;
Electronic control unit, described electronic control unit connects respectively described drive motor and described pressure sensor.
Further, between bolt of rear end plate and sleeve pipe, be also provided with lining.
Further, on described brake pedal arm, be also provided with total pump push rod mounting hole.
The invention provides a kind of electric power brake pedal structure, by gear transmission mode, by assist motor output torque, be converted into the booster torquemoment of brake pedal, the function that has realized brake pedal self power-assisted, power-assisted is swift in response, and assist rate can accurately be controlled in digitalisation, can improve the power-assisted sensitivity of braking, reduce car load stopping distance, substitute original vacuum booster power-assisted mode, compact conformation simultaneously, reduce taking of space, be conducive to the layout of car load.

Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, electric power brake pedal structure of the present invention is described in further details.Should be understood that following examples are only for the present invention is described but not for limiting scope of the present invention.
Referring to Fig. 1 and Fig. 2, electric power brake pedal structure of the present invention comprises brake-pedal support 1, drive motor support 2, drive motor 3, driven wheel 4, brake pedal arm 5, brake pedal 6.Drive motor 3 is fixed on brake-pedal support 1 by drive motor support 2.Brake pedal arm 5 one end are set to tooth fan structure 7, and the other end is connected with brake pedal 6.Driven wheel 4 is fixed with one with the drive motor output shaft 8 on drive motor 3, and engages with the tooth fan structure 7 on brake pedal arm 5.On drive motor support 2, be also provided with bolt of rear end plate 9, brake pedal arm 5 is welded as a whole with sleeve pipe 10, can centered by bolt of rear end plate 9, rotate.Between bolt of rear end plate 9 and sleeve pipe 10, be also provided with lining 11, for reducing friction drag.Between brake pedal arm 5 and drive motor support 2, be provided with pull back spring 12, in the time of pin loosen the brake 6, pull back spring 12 is for being returned to initial position by brake pedal 6.On brake pedal arm 5, be also provided with total pump push rod mounting hole 13, for fixing master brake cylinder push rod, in the time that pin is stepped on brake pedal 6, the output point that this point is external power output.Brake pedal 6 inside are provided with pressure sensor 14, in order to gather the size of treadle effort, information are passed to electronic control unit ECU, and electronic control unit ECU externally exports the size of controlling current control power-assisted.
When use, by brake-pedal support 1, whole electric power brake pedal structure assembly is fixed on vehicle body.In the time that pin is stepped on brake pedal 6, the pressure sensor 14 that is positioned at brake pedal 6 inside by pressure signal transmission to electronic control unit ECU, electronic control unit ECU is according to pressure size, export corresponding control electric current to drive motor 3, drive motor 3 rotates output torque, by being connected in the driven wheel 4 on drive motor output shaft 8, moment of torsion is passed to the tooth fan structure 7 driving on pedal arm 5, thereby realize brake pedal assist function.In the time of pin loosen the brake 6, pressure sensor 14 is by pressure signal transmission to electronic control unit ECU, and electronic control unit ECU externally exports and controls electric current is zero, and under the effect of pull back spring 12, brake pedal 6 is got back to initial position.
The invention provides a kind of electric power brake pedal structure, by gear transmission mode, by assist motor output torque, be converted into the booster torquemoment of brake pedal, the function that has realized brake pedal self power-assisted, power-assisted is swift in response, and assist rate can accurately be controlled in digitalisation, can improve the power-assisted sensitivity of braking, reduce car load stopping distance, substitute original vacuum booster power-assisted mode, compact conformation simultaneously, reduce taking of space, be conducive to the layout of car load.
