The operation principle of multiple-effect spot-type disc brake of the present invention is as described below：This brake adapted double-acting cylinder
（Or hydraulic cylinder）, according to input and output gas（Or liquid）Different compound modes, has four kinds of working methods, is respectively：
1st, ante-chamber air inlet, back cavity not air inlet, referred to as brake double brake.When ante-chamber air inlet, pressure gas apply a force upon
On secondary piston, now back cavity not air inlet, before in back cavity, power is superimposed upon by cluster spring further through back cavity inner carrier and rear piston rod
On piston.Now, two make a concerted effort to act on the brake arm of left and right by secondary piston bar, will make a concerted effort to be delivered to friction plate through bearing pin
On, brake implements double brake to brake disc.
2nd, ante-chamber air inlet, back cavity air inlet, referred to as brake air list are braked.When ante-chamber, back cavity air inlet simultaneously, in back cavity
After piston drives under pressure gas effect afterwards, piston rod compression cluster spring leaves ante-chamber piston, and the air thrust of only ante-chamber pushes away
Spring before dynamic secondary piston compression, power is acted on the brake arm of left and right by secondary piston bar, will make a concerted effort to be delivered to rub through bearing pin
In pad, the braking of air list is implemented in brake to brake disc.
3rd, ante-chamber not air inlet, back cavity not air inlet, referred to as brake Single spring are braked.When front/back cavity not air inlets, back cavity
Interior combination compression spring act on secondary piston bar by rear piston rod, secondary piston bar but by spring-force driven dual in left and right brake arm
On, transfer force on friction plate through bearing pin, Single spring braking is implemented in brake to brake disc.
4th, ante-chamber not air inlet, back cavity air inlet, claim brake release.When pressure air enters back cavity, rear piston is in air pressure
In the presence of, after drive, piston rod compression cluster spring leaves secondary piston, and the secondary piston being released pushes away front compression spring
Under dynamic, also move right, thus also driving secondary piston bar, intracavity shrinks forward, left and right brake arm in the presence of extension spring, around pin
Axle performs relative motion, and meanwhile, on the brake arm of left and right, two friction plates perform relative motion, thus discharging brake.
The scope of the present invention is not limited to above-described embodiment, and it is obvious that every foundation the technology of the present invention principle is made
Technology deformation, each falls within protection scope of the present invention.
