Title:
BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/132938
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a braking device capable of providing a sufficient braking force upon the occurrence of an abnormal condition. The braking device is equipped with a stroke simulator (5) which is connected between a master cylinder (3) and a valve (21) in an oil passage (11) that connects between the master cylinder (3) and a wheel cylinder (8), the stroke simulator (5) generating a brake operation reaction force with the increase/decrease in the volume of a positive pressure chamber (511) formed within the stroke simulator (5). When control is performed by a by-wire control unit (101), the brake fluid stored in a first chamber (31S) of the master cylinder (3) flows into the positive pressure chamber (511), and the available supply of liquid from the first chamber (31S) is greater than the amount of liquid capable of being absorbed by the positive pressure chamber (511).
