AUTOMATIC RELEASING DEVICE FOR STEPPING-ON TYPE PARKING BRAKE DEVICE

摘要

PURPOSE:To automatically release the brake operation by releasing the engagement of a stopper member engaged with the engagement teeth of an engagement member formed integrally with the pedal of a stepping-on type parking brake by driving an electromagnetic actuator, when the stepping-on operation of an accelerator pedal is detected and the speed change position is in traveling state. CONSTITUTION:Engagement teeth are formed on the outer peripheral edge of an engagement member 15 formed integrally with a pedal arm 16 for supporting the pedal 17 of a stepping-on type parking brake, and a ratchet hook at the top edge of a swingable stopper member is installed in free engagement. The release operation is carried out, through an adjusting plate 24 and a release member 22 by driving an electromagnetic actuator 21. The electromagnetic actuator 21 is driven when the speed change position is in traveling state and the accelerator pedal stepping-on operation is carried out. Therefore, the release operation for the foot stepping-on type parking brake can be automatically carried out, and the load in the operation for a driver can be reduced.
