Embodiment Construction

[0025] figure 1 It is a structural schematic diagram of the brake pedal of the present invention. figure 2 It is a structural schematic diagram of the brake pedal of the present invention. to combine figure 1 and figure 2 Do as follows. The brake pedal may be a brake pedal with mechanical brake feel simulation. The brake pedal can include that the pedal arm 1 is connected to the pedal connecting shaft 6 by connecting the fork arm 2 and the pedal connecting arm 17, the pedal connecting shaft 6 is connected to the vacuum booster, the pedal displacement sensor 5 is installed at the pedal arm 1, and the pedal arm 1 moves During the process, the pedal displacement sensor 5 converts the displacement signal of the pedal arm 1, and outputs the displacement signal of the pedal arm 1 to the core electronic control unit of the vehicle control decision, transmits the pedal stroke signal in real time, and adjusts the braking force to achieve the uniqueness of the braking foot feel. ...

Abstract

The invention provides a brake pedal, and relates to the field of vehicle chassis. The brake pedal comprises a pedal arm and a spring assembly, wherein the pedal arm is connected with a pedal connecting shaft through a connecting fork arm and a pedal connecting arm, the pedal connecting shaft is connected with a vacuum booster, and a pedal displacement sensor is installed at the pedal arm; the spring assembly comprises a reset spring and an adjusting spring, the reset spring is installed at a pedal-arm rotating shaft, the adjusting spring is composed of multiple spring bodies, and is fixedly installed at a fixing mechanism connected with a second pin shaft, and the second pin shaft is fixed at the pedal arm. By means of the brake pedal, the problem that as a brake pedal in the prior art cannot meet the requirement of a driver for the brake foot feeling, brake efficiency is low is solved.

Description

technical field [0001] The invention relates to the field of vehicle chassis, which relates to a brake pedal. Background technique [0002] At present, most of the service brake systems used in cars are servo brake boosters. The servo brake system is formed by adding a power servo device on the basis of the hydraulic brake system. When the driver takes a brake operation, he applies the brake force on the brake pedal and transmits the brake force to the brake master cylinder through the rod system. On the piston, the servo device also works at the same time, and supplies most of the braking energy, which can reduce the driver's operating intensity. If the servo fails, the original hydraulic brake can still function, and the driver needs a larger braking force to meet the needs of the vehicle brake. There are mainly two types of servo braking devices used in cars: vacuum servo and air pressure servo. [0003] The vacuum booster servo brake device provides boost by installin...
