PROBLEM TO BE SOLVED: To reduce energy loss of a brake driving device.SOLUTION: A brake driving device 100 is provided with: a cylinder 21; a drive piston 30 which divides the inside of the cylinder 21 into a first fluid pressure chamber 25 and a second fluid pressure chamber 26; and an actuator 40 which linearly moves the drive piston 30 along an inner peripheral surface of a first cylinder part 22, in which hydraulic fluid is supplied and discharged to and from the first fluid pressure chamber 25 and the second fluid pressure chamber 26 in accordance with movement of the drive piston 30, and the hydraulic fluid is circulated between the first fluid pressure chamber 25 and a brake device 10 to drive the brake device 10 in accordance with the movement of the drive piston 30.SELECTED DRAWING: Figure 1
【課題】ブレーキ駆動装置のエネルギロスを低減させる。【解決手段】ブレーキ駆動装置100は、シリンダ21と、シリンダ21内部を第1流体圧室25及び第2流体圧室26に区画する駆動ピストン30と、駆動ピストン30を第1シリンダ部22の内周面に沿って直線運動させるアクチュエータ40と、を備え、第1流体圧室25及び第2流体圧室26には、駆動ピストン30の移動に伴い作動油が給排され、駆動ピストン30の移動に伴い第1流体圧室25とブレーキ装置10との間で作動油を流通させてブレーキ装置10を駆動する。【選択図】図1
