Problems solved by technology

[0003] Most of the traditional brake pedals do not have structures with adjustable lever ratios. Even if they do, they are considered from the perspective of the overall structure of the pedal arm. The structure is complex, the manufacturing process and production are difficult, and the cost is increased. It is difficult to realize in practice, and the structure cannot be universalized.

Abstract

The invention discloses an automobile brake pedal structure with an adjustable lever ratio. The automobile brake pedal structure comprises a brake pedal arm, a push rod of a vacuum booster and a brake pedal main support. A pedal pad is arranged at the lower end of the brake pedal arm,, the upper end of the brake pedal arm is connected with the brake pedal main support by a rotary shaft, the brake pedal arm is connected with the vacuum booster on an automobile body by the push rod of the vacuum booster, holes are formed in the brake pedal arm and the brake pedal main support, and the rotary shaft and the holes are connected with one another in such a manner that the rotary shaft and the holes can be repositioned relatively. The automobile brake pedal structure has the advantages that the rotary shaft can be repositioned in the brake pedal main support and the brake pedal arm, so that the lever ratio can be adjusted, different lever ratio requirements of different automobile types can be met, the brake pedal structure is rarely modified, is simple and is convenient to manufacture and mount and low in cost, universality of the brake pedal structure can be facilitated, the development cycle can be shortened, and the development cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an automobile brake pedal structure with adjustable lever ratio. Background technique [0002] In the automobile braking system, the structure of the brake pedal of different models is different, or it is affected by the layout of the whole vehicle, or the influence of the lever ratio of the pedal. The brake pedal needs to be changed or newly developed to meet the layout and performance requirements. This not only increases design verification time, but also increases component costs. [0003] Most of the traditional brake pedals do not have structures with adjustable lever ratios. Even if they do, they are considered from the perspective of the overall structure of the pedal arm. The structure is complex, the manufacturing process and production are difficult, and the cost is increased. It is difficult to realize in practice, and the structure cannot be universalized....
