The working principle of multiple-effect caliper disc brake of the present invention is described below: this break adapted double-acting cylinder (or oil hydraulic cylinder), according to input and output gas (or liquid) different combinations mode, have four kinds of working methods, be respectively:
1, ante-chamber air inlet, not air inlet of back cavity is called the two brakings of break.When the ante-chamber air inlet, pressure gas is applied to power on the secondary piston, not air inlet of back cavity this moment, and cluster spring is superimposed upon power on the secondary piston through back cavity inner carrier and back piston bar again in the back cavity.At this moment, two act on the brake arm of the left and right sides through the secondary piston bar with joint efforts, will make a concerted effort to be delivered on the friction plate through bearing pin, and break is implemented two brakings to brake disc.
2, ante-chamber air inlet, the back cavity air inlet is called the braking of break air list.When ante-chamber, back cavity air inlet simultaneously; Back piston drives back piston bar compression cluster spring and leaves the ante-chamber piston in the back cavity under the effect of pressure gas; Have only the air thrust of ante-chamber to promote secondary piston compression front spring; Power is acted on the brake arm of the left and right sides through the secondary piston bar, will make a concerted effort to be delivered on the friction plate through bearing pin, break is implemented the braking of air list to brake disc.
3, not air inlet of ante-chamber, not air inlet of back cavity is called break list spring braking.Current, back cavity is during not air inlet; The combined compression spring acts on the secondary piston bar through the back piston bar in the back cavity; The secondary piston bar acts on spring force on the brake arm of the left and right sides again, through bearing pin power is delivered on the friction plate, and break is implemented single spring braking to brake disc.
4, not air inlet of ante-chamber, the back cavity air inlet claims that break discharges.When pressure air got into back cavity, back piston drove back piston bar compression cluster spring and leaves secondary piston under the effect of air pressure; The secondary piston that obtains discharging also moves right under the promotion of preceding pressure spring, shrinks in ante-chamber thereby also drive the secondary piston bar; Left and right sides brake arm is done relative movement around bearing pin under the effect of extension spring, simultaneously; Two friction plates are done relative movement on the brake arm of the left and right sides, thereby discharge break.
Protection domain of the present invention is not limited to the foregoing description, and every conspicuous technology distortion of doing according to know-why of the present invention all falls within protection scope of the present invention.
