Title:
LIQUID PRESSURE BRAKING DEVICE
Document Type and Number:
Japanese Patent JP2016097788
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid pressure braking device capable of improving brake feeling.SOLUTION: The liquid pressure braking device includes a fluid supply source 18, pressure adjusting means 66 for adjusting liquid pressure supplied from the supply source and liquid pressure discharged to a reservoir 16, a fluid chamber 64 into which the liquid pressure is introduced from the supply source via the pressure adjusting means, an assisting piston 30 facing the fluid chamber and configured to assist the master piston by receiving the liquid pressure introduced into the fluid chamber, an expansion piston 30e facing the fluid chamber and configured to expand the volume of the fluid chamber by receiving the liquid pressure introduced into the fluid chamber, an engaging part 30d for engaging the assist piston and the expansion piston with each other after the expansion of the volume of the fluid chamber, and a reaction force member 72a for generating a reaction force in a direction for suppressing the expansion of the volume by the expansion piston and releasing the engagement after discharging of the liquid pressure from the fluid chamber to the reservoir, and the assisting of the assisting piston is carried out during or after the expansion of the volume of the fluid chamber by the expansion piston.SELECTED DRAWING: Figure 1
