Unit brake cylinder piston component is integrally pulled out by guide blot 16 simultaneously, so that activation lever realizes parking braking.
Under parking braking state, compressed air is filled with to parking in cylinder body 1, the compression of piston 8 is parked and parks energy-storaging spring 7
Motion upwards.Sphenoid 14 is also moved upwardly together therewith, and realizes in the presence of sphenoid back-moving spring 13 sphenoid 14
Complete reset.Due to moving up for sphenoid, in the presence of release of brake spring A3, brake unit piston component pulls thrust
Set 15 resets, so as to realize that the inflation of parking braking is alleviated.
Under parking braking state, pull hand to alleviate drawstring 31, draw pin 22 to drive drag hook 27 to disengage ratchet 5, so as to release
To ratchet and park the constraint of screw rod rotary freedom.In the presence of sphenoid back-moving spring 13, screw rod rotation is parked,
Sphenoid 14, which drives, parks the motion upwards of swivel nut 2, meanwhile, in the presence of brake unit release spring A3, brake unit piston
Component pulls thrust sleeve 15 to reset, so as to realize the hand relieving of parking braking.
After hand relieving operation is carried out, if rethinking using function is parked, first have to, to inflation in cylinder is parked, park work
Plug parks the motion upwards of energy-storaging spring 7 by lower thrust-bearing 9, the compression of lower spring cup 10.Now, due to parking swivel nut 2 and wedge
Body 14 is connected motionless, and parking screw rod 3 will move upwards, and parking swivel nut 2 makes to parking 3 one downward active forces of screw rod
The contact surface for parking screw rod 3 and lower spring cup 10 is disengaged, and is parked screw rod 3 and is passed through shop bolt 11 and the semi-spherical grooves for parking piston
8-2 is contacted, and is so parked piston and is transmitted the force to and park screw rod 3, parks screw rod 3 and rotate upward motion, park screw rod with
Park swivel nut and screw reset.
