The working principle of braking clamp 1 is as follows.Barrier film cylinder or leather cup cylinder 5 fill wind with retardation pressure C.Piston carries out a stroke, and by lever 12 eccentric rotation axis 10.The brake calipers tappet 6 that is contained on the eccentric axle head 11 enters application position.Because it links to each other with depression bar regulator 7, so the brake calipers tappet 6 on opposite also enters application position.In case the stroke of piston has surpassed the setting value in brake lining gap, then place the rotatable drawbar on the lever 12 to begin to press to the roller bearing rocking bar.In the stroke of piston that continues, depression bar 13 can be driven with the wishbone (see figure 3) that is connected with the roller bearing rocking bar by the roller bearing rocking bar.Depression bar 13 embeds in the outer layer sleeve 14 of depression bar regulator 7, drives rotating shaft 15 rotations.Pipe thread nut 16 in the rotating shaft 15 simultaneously also carries out axial motion, has so just prolonged the depression bar regulator.And because variation has taken place depression bar regulator length, then the gap between brake pad and the friction plate is reduced.Depression bar regulator 7 is clearance adjusters of a single effect, stressed control, that is to say, only regulates automatically in one direction, therefore is called single effect, and when regulator length becomes big, the brake lining gap will reduce.
By the adjusting of piston force, even to such an extent as under the different situation of the elastic extension amount of the continuous variation of clamping force caliper component, also can keep the brake lining gap constant, therefore be called the clearance adjuster of stressed control.
Brake pad as shown in Figure 3.The perspective view of brake disc as shown in Figure 4, the parts explosion of brake disc is as shown in Figure 5.Fig. 6 illustrates braking clamp, brake disc and brake lining and is installed in perspective view on the rail vehicle.Referring to Fig. 6, brake disc 2 can not be installed on the wheel axle 17 with respect to the wheel axle 17 of rail vehicle with relatively rotating, and braking clamp 1 can make brake lining 3 and brake disc 2 rubbing contact, in order to carry out the braking of rail vehicle.The concrete installing space relation of moving clamp, brake disc and brake lining is as Fig. 7-shown in Figure 9.
Wherein above-mentioned brake rigging is according to method manufacturing as described below, thereby makes the constructing variable of braking clamp 1, brake disc 2 and brake lining 3 be complementary with the parameter of predetermined working line and the parameter of rail vehicle aspect thermomechanics.
