Wherein, being provided with installing plate 34 in described mounting seat 21, described jaw actuator mechanism is an overall structure before installing with configuration in railroad truck, and described installing plate 34 is fixed on by screw rod under the bogie of rail truck.
As shown in Figure 3, described pivoted arm 7 lower end is provided with block 15, described block 15 coordinates with sensor composition, described sensor composition adjusts device 14 corresponding matching by graduating stem 16 with lock, when after brake lining composition abrasion, the gap of brake disc and brake lining composition increases, by the movement of graduating stem 16, make described lock adjust device 14 action, reduce the gap between brake disc and brake lining composition；Described sensor composition includes connecting rod 17, fixing seat 18, guide pillar 19 and adjusts spring 20, described fixing seat 18 and guide pillar 19 are fixed in mounting seat 21, described connecting rod 17 one end and block 15 corresponding matching of pivoted arm 7 lower end, its other end is hinged with fixing seat 18, in the middle part of described connecting rod 17 hinged with the slide block 22 being slidably connected on guide pillar 19, described slide block 22 is hinged with graduating stem 16 one end, described adjustment spring 20 is socketed on guide pillar 19, described adjustment spring 20 one end is resisted against slide block 22 end face, and its other end is resisted against on fixing seat 18.
nullAs shown in Figure 4，Described lock adjusts device 14 to include right body composition 23、Left body composition 24、Adjusting nut 25 and screw rod composition 26，Described right clamp forms 3 rearward end and right body, and to form 23 hinged，It is hinged that described left clamp composition 2 and left body form 24，In described adjusting nut 25 is arranged on right body composition 23 and form 26 with screw rod to threaded，On described adjusting nut 25、It is socketed with holddown spring 27 between adjusting nut 25 and right body composition 23，Described screw rod forms 26 lower ends and is placed in left body composition 24，Described screw rod forms 26 lower end edges and is formed radially driving lobe 28，Described driving lobe 28 side and graduating stem 16 other end against，Its other end be arranged on left body composition 24 in cone spring 29 against，Described screw rod composition 26 is connected with unilateral bearing 30，Described screw rod forms 26 ends and is connected with rollback nut 31.
Wherein, form 24 end faces at described left body and be provided with fairlead 32, described fairlead 32 is enclosed within adjusting nut 25 bottom, it is provided with scalable dust cover 33 between described right body composition 23 and left body composition 24, described scalable dust cover 33 one end is connected with right body composition 23, and its other end is connected with fairlead 32.
The operation principle of the present invention: when car braking, checking cylinder action, eccentric shaft turns is driven by pivoted arm, thus utilize the rotation of eccentric shaft, make right clamp form clamp composition to the left mobile, brake disc is clamped, if now the gap between brake disc and brake lining composition is normal, the interlinking lever end that then block of pivoted arm lower end forms with sensor will not contact, and lock adjusts device to be failure to actuate.
nullIf brake lining causes the gap between brake disc and brake lining composition to increase because wearing and tearing，The interlinking lever end that the block of pivoted arm lower end forms with sensor contacts and promotes it to rotate，The rotation of connecting rod then band movable slider along guide pillar forward slip and compresses adjustment spring，Graduating stem then synchronizes to move forward with slide block，Simultaneously，Graduating stem right-hand member against screw rod composition lower end driving lobe poised state be broken，Lobe is driven to drive screw rod composition to rotate under cone spring effect，Until the block of pivoted arm lower end no longer promotes interlinking lever end to rotate，The rotation of screw rod composition then drives adjusting nut to move along its axis relative to screw rod composition，Adjusting nut drives left body composition mobile simultaneously，So，Make a left side、The leading section of right clamp composition clamps to brake disc simultaneously further，Thus reduce the gap between brake disc and brake lining，The gap between brake disc and brake lining is made to reach the normal requirement of Brake Design.Now, graduating stem right-hand member is resisted against driving lobe again, and owing to screw rod composition is connected with unilateral bearing, therefore screw rod composition cannot turn round again, the now stable position after rotation of connecting rod, to ensure in upper once braking procedure, right clamp composition turns to meet the position of brake request.
When brake disc increases again with brake lining gap, lock adjusts device reoperation to reduce the gap between brake disc and brake lining；After brake lining composition is changed, screw rod composition revolution can be made by rollback nut, make adjusting nut be returned to original state.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
