Embodiment Construction
[0034] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0035] The present invention provides a three-redundant all-electric brake actuation system. The motor 23 extends out of the shaft 16 through the motor, and the rotational motion of the motor 23 is transmitted to the lead screw nut 18 through a set of gears, and the rotating motion of the motor 23 is transmitted through the ball screw 19. Motion is converted to linear motion. The motor 23 and the resolver 22 are connected to an external drive controller and power supply through the motor electrical connector 14 . When the lead screw 19 moves forward in a straight line and presses the brake disc assembly 3, the reaction force of the brake disc assembly 3 is transmitted to the thrust bearing and the pressure sensor 21 through the guide mechanism, and the pressure sensor 21 converts the elastic deformation into an electrical signal and transmits it...
