Description

Automotive brake away system

The present invention relates to a vehicle brake away system, and more particularly, to a vehicle brake away system capable of improving productivity and quality while being configured in a relatively simple configuration.

Generally, a braking device is configured to decelerate or stop a vehicle or maintain a certain position. Such a braking device is largely a component for generating a force required for braking by a driver, such as a brake pedal, and by this force, a hydraulic element (for example, a master bag) or a mechanical configuration (for example, a drum) is used. It consists of a component for obtaining a stopping force through, and an auxiliary device used for the purpose of braking transmission between these components.

Among these, the brake pedal, which is braked by the driver, is mounted inside the vehicle and repeatedly used so that no accident occurs by the driver. However, such a brake pedal may cause injury to the driver's leg when the dash panel is deformed into the interior while the engine is pushed backward due to an accident such as a frontal collision of the vehicle.

Thus, even if the dash panel is pushed into the interior due to a crash accident, the brake away system is provided to separate the brake pedal from the dash panel by the collision load to prevent injury to the driver.

The present invention relates to a brake away system disclosed in Korean Patent No. 10-0298053, in which a collision load does not act on the pedal arm through a resonance action. In the brake away system of Patent Document 1, when the collision detection mechanism 27 detects a front collision of the vehicle, the pedal arm 2 is connected to the push rod lever 15 that connects the push rod 14 of the master bag 13. ), The clutch mechanism 18 for integrally connecting is removed. Therefore, even if the push rod 14 is moved rearward together with the master bag 13, the push rod lever 14 makes a resonant operation that is idle, so that a collision load is applied to the pedal arm 2. It will not work. Therefore, by preventing the collision load from acting on the pedal arm through the push rod of the master bag during the front collision of the vehicle, the stepped position of the brake pedal is displaced rearward, thereby preventing the occurrence of discomfort.
