Abstract

The invention discloses a linear adjustable pedal feeling simulator and its brake pedal mechanism. The brake pedal mechanism includes a mounting bracket, a brake pedal, a linear adjustable pedal feeling simulator and an inductive sensor. The inductive sensor is used for pre-sensing driving The driver's braking intention, the pedal displacement sensor is used to accurately identify the driver's braking intention, and the pedal feeling simulator includes a shell, a first elastic component, a second elastic component, a third elastic component, a drive connection mechanism and an emergency switch. Compared with the prior art, the present invention sequentially adopts the second elastic component, the first elastic component, and the third elastic component in order to simulate the main function respectively, which can effectively simulate the operation feeling of the brake pedal mechanism, and the driving connection mechanism can realize braking. The adjustment of the dynamic 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 a linear adjustable pedal feeling simulator and a 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 brake-by-wire system realizes the decoupling of the brake pedal me...
