Detailed Description
The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.
As shown in fig. 1-4, the present utility model provides a brake-by-wire apparatus for an equation motorcycle, comprising: brake motor 110, rocker arm 120, slider 130, brake pedal 140, master cylinder 150, accelerator pedal 160, tie rod 170, boss 171, spring 180, and base 190.
The base 190 is horizontally arranged, the brake pedal 140 is supported and arranged at one end of the base 190 and the accelerator pedal 160 is supported and arranged at the other end of the base, one end of the brake mechanism is supported and arranged on the base 190, and the other end of the brake mechanism is connected with the upper part of the brake pedal 140; the brake motor 110 is fixedly arranged on the frame, one end of the rocker arm 120 is connected with the output end of the brake motor 110, the other end of the rocker arm 120 is connected with one end of the pull rod 170, one end of the slide block 130 is connected with the top of the brake pedal, the other end of the pull rod 170 passes through the other end of the slide block 130, is arranged inside the slide block and can axially move along the slide block 130, a spring 180 is further arranged inside the slide block 130, the spring 180 is arranged on the pull rod 170, one end of the spring 180 abuts against the other end of the pull rod 170, and the other end abuts against the inner wall of the other end of the slide block 130.
On the other end of the pull rod 170, a boss stopper 171 is fixedly provided, one end of a spring 180 abuts against the boss stopper 171, and the brake mechanism includes: the two brake master cylinders 150 are respectively positioned at two sides of the brake pedal 140, one end of each brake master cylinder 150 is supported and arranged on the base 190, and the other end of each brake master cylinder 150 is connected with the upper part of the brake pedal 140. The rocker arm 120 is splined to the output of the brake motor 110.
The brake motor 110 is used for providing power during brake-by-wire, the magnitude of the braking force is controlled by controlling the rotation angle, and the rocker arm 120 is used for connecting the brake motor 110 and the pull rod 130; the pull rod is used for connecting the spring 180 and the slider 130, the slider is used for connecting the brake pedal 140 and the spring 180, the brake pedal assembly is a device for generating braking force, and a driver presses the brake pedal to generate braking force.
