Abstract:
A hydraulic compensation device for compensating a positional deviation of a brake pad which is wearable due to its braking action and which, in use, is mounted on and controlled by a hydraulic actuator, the hydraulic compensation device comprising:a container adapted to receive a brake oil to be supplied to the hydraulic actuator, said container having a first end portion formed with an oil passage adapted to be communicated with the hydraulic actuator, and a second end portion opposite to said first end portion;a piston slidably mounted inside said container adjacent to said first end portion to confine the brake oil with said first end portion;a push member rotatably disposed inside said container at one side of said piston adjacent to said second end portion of said container and abutting against said piston, said push member being threadedly movable relative to said container so as to push said piston toward said first end portion, thereby moving the hydraulic actuator and adjusting the position of the brake pad;an indicating rod integral with and projecting axially from said push member and extending outwardly of said container through said second end portion of said container for indicating amount of displacement of said push member; andscrew thread means provided on said container and said push member to permit said push member to threadedly move relative to said container for adjustment of the position of said piston.
