Title:
HYDRAULIC BRAKE SYSTEM AND BRAKE OPERATION DEVICE
Document Type and Number:
Japanese Patent JP2017171015
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce, for example, a difference in operation feeling between when temperature is low and when temperature is normal, in a hydraulic brake system in which a stroke simulator and a pump are connected.SOLUTION: A stroke simulator 48s and a suction mechanism 40 are connected by a first passage 60 and a second passage 62 provided with a diaphragm 70. A first connection part 64 of the first passage 60 is provided closer to the pump 32 than a second connection part 66 of the second passage 62. When temperature is low, a hydraulic liquid is less likely to be supplied to the second connection part 66 via the second passage 62. When temperature is normal, the hydraulic liquid is easily supplied to the second connection part 66 via the second passage 62. As a result, a stroke increase resulting from a suction operation of the pump 32 is restricted when temperature is normal than when temperature is low. Accordingly, a difference in operation feeling between when temperature is normal and when temperature is low can be reduced.SELECTED DRAWING: Figure 1
