Title:
ELECTROMECHANICAL BRAKE BOOSTER AND METHOD FOR OPERATING ELECTROMECHANICAL BRAKE BOOSTER
Document Type and Number:
Japanese Patent JP2016003008
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce motor damage risk by securing the possibility of sensing anchorage/lock of a brake operation member in automatic braking.SOLUTION: A valve disc 12 moved by shift in a brake direction can shift to a difference stroke d equal to a predetermined limit difference stroke d0 associated with an input rod 14 so long as a holding force Fr falling below a predetermined threshold value Fr0 even high acts by resisting an interlock shift movement. Next, the input rod 14 can be moved by interlock shift in the brake direction. In this case, at least one buffer member 16 is arranged in the input rod 14 and/or valve disc 12, so that the difference stroke d can increase beyond the predetermined limit difference stroke d0 under a deformation of at least one buffer member 16 so long as the holding force Fr rising above the predetermined threshold value Fr0 acts by resisting an interlock shift movement.
