Description
Technical Field
The invention belongs to the technical field of automobiles, and particularly relates to a brake pedal.
Background
The brake pedal is an important ring in a closed loop system of a driver and a whole vehicle man-machine, the driver senses the braking feeling of the vehicle through the brake pedal and controls the braking strength of the vehicle, a pedal arm of the traditional brake pedal is directly connected with a push rod of a booster, the brake pedal is stepped down by the driver in the motion process of the mechanism, the pedal arm rotates around a fixed point, the push rod of the booster is directly pushed, and the transmission of the pedal force is realized. Therefore, after the design and the design of the pedal structure, the lever ratio is a fixed value in the whole pedal stroke process, and due to factors such as the idle stroke of a brake system, the pipeline pressure of the initial brake system and the like, the pedal force is small in the initial stage of the pedal, but the stroke is large, so that the response of braking force is not timely, the braking distance of the vehicle is increased, the pedal force is large in the later stage, but the stroke is small, and further the pedal feeling state is poor when the whole vehicle is braked.
At present, the chinese patent network discloses an anti-intrusion variable lever ratio brake pedal [ grant No.: CN206954209U, including the footboard, footboard arm and the footboard installing support that is connected with the footboard, still include two power rods, the pendulum rod, the booster push rod, prevent invading the support, the upper end of footboard arm is connected with the lower extreme of preventing invading the support through first pivot, the upper end of preventing invading the support is fixed, upper portion one side of footboard arm is connected with the right-hand member of two power rods through first round pin axle, the left end of two power rods is connected with the pendulum rod through second round pin axle, the lower extreme of pendulum rod is fixed through the pivot with the footboard installing support, the top of pendulum rod is connected through third round pin axle with the booster push rod, the upper end right side of pendulum rod is provided with the support arm that the support extends is prevented invading to the orientation, the right-hand member of support arm contacts with the support of preventing invading. The distance between the first rotating shaft and the pedal is Ra, the distance between the first rotating shaft and the second pin shaft is Rb, the distance between the second rotating shaft and the third pin shaft is Rc, the distance between the second rotating shaft and the second pin shaft is Rd, and the lever ratio of the brake pedal is Ra
In the working process of the brake pedal, the distance Ra between the first rotating shaft and the pedal, the distance Rc between the second rotating shaft and the third pin shaft and the distance Rd between the second rotating shaft and the second pin shaft are not changed, and only the first rotating shaft and the second rotating shaft are connectedThe distance Rb between the second round pin axle changes, therefore the brake pedal lever ratio is the inverse proportion function, when the distance Rb between first pivot and the second round pin axle grow, the brake pedal lever ratio diminishes, when the distance Rb between first pivot and the second round pin axle diminishes, the brake pedal lever ratio grow, but in whole braking process, the distance Rb between first pivot and the second round pin axle changes very little, and then make the change range of whole brake pedal lever ratio very limited, and then compare with traditional footboard structure, braking response and the pedal sense state change in whole car braking process do not have very obvious difference, the improvement to the pedal sense state is not enough far away.
