Brake pedal with adjustable lever ratio for vehicle

Abstract

The invention discloses a vehicle brake pedal with adjustable lever ratio, which comprises a pedal base, a pedal bracket and a pedal arm, the pedal arm is installed on the pedal bracket, and the pedal bracket is installed on the pedal base , the pedal base is connected with the car body through bolts, the pedal arm is composed of two parts, the upper arm of the pedal and the lower arm of the pedal, and the upper arm of the pedal and the lower arm of the pedal are equipped with corresponding adjustment devices, and the adjustment device consists of A longitudinal adjustment groove and a transverse adjustment groove are formed, and the adjustment device at least includes two or more longitudinal adjustment grooves, and the longitudinal adjustment groove communicates with the horizontal adjustment groove. The invention has the ability to adjust the pedal lever ratio according to the driver's different needs for the pedal feeling, and can provide more convenient pedal parameters for the performance matching of the braking system, so as to design a braking system with better pedal feeling; the manufacturing cost is low, Low maintenance cost, long service life and so on.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis component manufacturing, and in particular relates to a brake pedal with an adjustable lever ratio for a vehicle. Background technique [0002] At present, in the field of automobile chassis parts manufacturing technology, especially the important part of the automobile chassis, the automobile brake pedal; Slow down and stop. It is one of the five major controls for car driving. The frequency of use is very high. How the driver controls directly affects the driving safety of the car. The brake pedal is commonly called as a brake, and a small pedal is connected to the brake lever on the brake, so this pedal is also called "brake pedal". There is also a small pedal above the clutch, called the clutch pedal. The clutch is on the left and the brake is on the right (along with the gas pedal, which is on the right). [0003] As we all know, the braking of a car is achieved by stepping o...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that in the prior art, since the pedal arms of the brake pedal are all fixed, if the pedal feels bad, it is necessary to replace the pedal with a different lever ratio and retest, which wastes matching time and cannot be realized. Optimal pedal feel; poor universal performance; insufficient intermediate strength, easy to break; greatly provides technical problems such as maintenance costs, and provides a brake pedal with adjustable lever ratio for vehicles
