Abstract

The invention discloses an improved manual release device for an electro-hydraulic disc brake. The improved manual release device comprises a base, an operating oil cylinder, a piston rod A, a force application rod seat, a connecting rod, a rotary support, a working oil cylinder, a piston rod B and an oil tank, wherein the operating oil cylinder is communicated with the oil tank through an oil way; a steel ball is arranged in the middle of the oil way for blocking; the working oil cylinder is communicated with the oil tank through two oil ways; a steel ball is arranged in the middle of the first oil way for blocking and is tightly pressed by an unloading screw; the second oil way is blocked by a safety electromagnetic valve; the operating oil cylinder is communicated with the working oil cylinder through an oil way; and a steel ball is arranged in the middle of the oil way for blocking. The function of the improved manual release device is that under the condition of power failure, the brake is opened manually or the brake is manually opened when a pusher of the brake is in failure; and in addition, the device is equipped with the safety electromagnetic valve, the accident potential caused by the fact that braking cannot completed during baking because pressure is forgotten to be relieved when the brake is opened due to maintenance or emergency power off is avoided.
