Embodiment
Extremely shown in Figure 6 according to Fig. 1, a kind of disk brake assembly that is used for heavy goods vehicles, its structure comprises lever system 1, self-regulating system 2, bearing system 3 and friction pair 4, described lever system 1, self-regulating system 2 are arranged on the bearing system 3, described lever system 1 connects friction pair 4, and also is provided with self-regulating system 2 between friction pair 4 and the lever system 1.
Described lever system 1 comprises the first quarter moon bearing support 12 that is used to install lever, widens lever assembly, piston assembly, whole push-plate 15, first quarter moon bearing support 11 cooperates the location to put into caliper by axis hole, widens the lever assembly and can freely rotate on first quarter moon bearing support 11 by the first quarter moon bearing; Be provided with pusher 28 in the piston assembly; Whole push-plate 15 is fixed in the piston assembly.
Offer radiating groove, gauge hole on the friction material 33 of described friction pair 4.
Described self-regulating system 2 comprises declutch shift shaft 21, intermediate gear 22, overrunning clutch 23, overload clutch axle 24, spring 23, overload clutch 26, overload clutch shell 27; Described declutch shift shaft 21 is connected by pusher 28, the piston 13 of piston assembly in the overload clutch 26, overrunning clutch 23, intermediate gear 22 and the lever system 1 that are in transmission connection successively.
Described bearing system 3 comprises the first quarter moon bearing support 11 and the housing of lever system 1, is split type clamp type structure, lever system 1, self-regulating system 2 that described bearing system 3 carryings are attached thereto.
As depicted in figs. 1 and 2, input power passes to lever system 1 earlier, by leverage input power is amplified, and ouput force passes to the friction pair element then, makes its friction-produced braking moment, thereby realizes braking effect.Self-adjustment structure is monitored the gap of friction pair 4 automatically, when the gap when setting numerical value, self-adjustment structure is started working, and lever system 1 is adjusted, thereby made the gap of friction pair 4 reach setting value.The carrying decorum 3 is carriers of these parts.
As shown in Figure 3, breaking force promotes lever assembly 12, makes it to rotate on first quarter moon bearing 11 by first quarter moon bearing assembly 16, wobbler action by lever assembly 12, straight pin 17 moves forward, and advances thereby promote push rod 18, by piston 13 whole push-plate 15 is advanced.First quarter moon bearing support 11 cooperates the location to put into caliper by axis hole, plays a supporting role; Widening lever assembly 12 can freely rotate on first quarter moon bearing support 11 by first quarter moon bearing assembly 16; Straight pin 17 is put into the circular hole of lever assembly 12, and the inside studs with lining, can guarantee that straight pin 17 is free movable, and push rod 18 and piston 13 are contained in by being threaded in the piston holder 14 that studs with piston bushing 19, and piston holder 14 is fixed on the caliper; Whole push-plate 15 is fixed on the piston 13 by circlip, and piston holder 14 ports have oil sealing 110.
As shown in Figure 4, declutch shift shaft 21 and 27 riveted joints of overload clutch shell, spring 25 is in compressive state after initial assembling, the size of this pressure has determined the slipping torque of overload clutch, when declutch shift shaft 21 begins to rotate, driving force passes to overload clutch 26 by overload clutch shell 27, driving force is transferred to overload clutch axle 24 then, between overload clutch axle 24 and the intermediate gear 22 overrunning clutch 23 is housed, the effect of overrunning clutch is that the gap that has guaranteed to compensate is not reduced, and that is to say that supposing to turn clockwise to compensate brake clearance, when turning clockwise so, overrunning clutch is a carry-over moment, and when being rotated counterclockwise, overrunning clutch will skid, overload clutch axle 24 can the cycle initial position, and intermediate gear 22 keeps original positions motionless.Declutch shift shaft 21 is strength input elements of controlling mechanism, and the geomery of declutch shift shaft 21 has determined the time of whole controlling mechanism effect.After input power is converted into moment of rotation by declutch shift shaft 21, pass to overload clutch 26 earlier, pass to overrunning clutch 23 then, pass to the pusher 28 and the piston 13 of both sides then by intermediate gear 22, the moment of rotation of final input be converted into piston 13 extending amount, thereby realize the compensation in gap.
As shown in Figure 5, hang on the backboard 32 after locking plate 31 compressions, friction material 33 is fixed on the backboard by special method of attaching.During braking, friction material contacts with brake disc, produces friction torque, realizes braking function.
