Abstract

The invention discloses an adjustable damping pedal feeling simulator and an automobile brake pedal mechanism thereof. The automobile brake pedal mechanism includes a mounting bracket, a brake pedal, an adjustable damping pedal feeling simulator, an induction sensor and a pedal displacement sensor. The adjustable damping pedal feeling simulator comprises a first pedal feeling simulating mechanism, a connecting mechanism, a second pedal feeling simulating mechanism, a brake push rod, a drive connecting mechanism and an emergency switch. Compared with the prior art, the present invention is used to pre-perceive the driver's braking intention, the pedal displacement sensor is used to accurately identify the driver's braking intention, and the braking can be realized through the adjustment of the hydraulic oil flow section and flow damping The adjustment of the working characteristic curve; compact structure, convenient operation, quick response, adjustable braking feeling, improved braking stability, comfort and safety, and has the functions of pre-identifying braking intention and emergency braking.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake equipment, and in particular relates to an adjustable damping pedal feeling simulator and an automobile brake pedal mechanism thereof. Background technique [0002] The braking system is one of the important components of the automobile chassis, which is directly related to the comprehensive performance of the automobile and the safety of life and property. Although the traditional hydraulic and pneumatic braking systems can meet the requirements of the existing braking regulations, there are complex pipeline arrangements, relying on vacuum booster devices, slow braking response speed, non-active adjustment of braking torque, and difficulty in matching Other deficiencies such as system integration control are not suitable for the development requirements of automobiles, especially electric vehicle chassis integration control. [0003] The electronically controlled braking system realizes th...
