Problems solved by technology

[0003] At present, in the braking performance matching test, the pedal with a fixed lever ratio i=L1 / L2 is installed on the car for the test, and the pedal feel is evaluated. If the pedal feel is poor, it is necessary to replace the pedal with a different lever ratio and try again. Wastes matching time and does not achieve optimal pedal feel

Abstract

The invention discloses an automobile brake pedal structure with an adjustable lever ratio. The automobile brake pedal structure with the adjustable lever ratio comprises a pedal support installed on an automobile body. One end of a first pedal arm is installed on the pedal support and the other end of the first pedal arm is provided with a second pedal arm. The end portion of the second pedal arm is provided with a pedal. The first pedal arm and the second pedal arm are respectively provided with a long-strip-shaped through hole. The first pedal arm and the second pedal arm are fixed together in the mode that bolts penetrate through the long-strip-shaped through holes of the first pedal arm and the second pedal arm. The two long edges of each long-strip-shaped through hole are respectively and symmetrically provided with a plurality of arc grooves. The bolts are installed in the arc grooves. The end portions of the bolts are locked through nuts. By the adoption of the automobile brake pedal structure with the adjustable lever ratio, it is guaranteed that in the process of use of the pedal, the lever ratio of the pedal can be adjusted by a driver according to the different requirements for the pedal feeling of the driver, pedal parameters convenient to utilize can be provided for performance matching of a brake system, and therefore the brake system with a good pedal feeling can be designed.

Description

technical field [0001] The invention relates to a brake pedal mechanism, in particular to a brake pedal structure with adjustable lever ratio for automobiles. Background technique [0002] The braking of the car is realized by stepping on the brake pedal, and the pedal produces a certain reaction force on the foot at the same time. As the requirements for driving comfort increase, the requirements for pedal feel when braking are also constantly increasing. [0003] At present, in the braking performance matching test, the pedal with a fixed lever ratio i=L1 / L2 is installed on the car for the test, and the pedal feel is evaluated. If the pedal feel is poor, it is necessary to replace the pedal with a different lever ratio and try again. It wastes matching time and fails to achieve optimal pedal feel. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a brake pedal structure with adjustable lever ratio for automobil...
