The front end of Bidirectional self-regulating stroke boosting brake cylinder 4 is hinged on the middle part of front brake lever 2, the rear end of Bidirectional self-regulating stroke boosting brake cylinder 4 is hinged on the middle part of rear brake lever 8, relative motion by front brake lever 2 and rear brake lever 8 triggers Bidirectional self-regulating stroke boosting brake cylinder 4 actions, and automatically elongates or shortens according to the gap length of brake brake shoe 10.
One end of hand brake lever 11 links to each other with car body hand brake device (not shown), and the other end of hand brake lever 11 links to each other with the adjusting parts of Bidirectional self-regulating stroke boosting brake cylinder 4.The application of force direction of hand brake lever 11 is shown in the arrow B among Fig. 2,13.The car body hand brake device is by 4 actions of hand brake lever 11 control Bidirectional self-regulating stroke boosting brake cylinders, and then the drive miscellaneous part is finished the braking to wheel 12.Hand brake lever 11 is seen following description with the concrete connection structure of Bidirectional self-regulating stroke boosting brake cylinder 4.
Referring to Fig. 4 ~ 11, an end of hand brake lever 11 is provided with pin-and-hole 11a, and pin-and-hole 11a links to each other with car body hand brake device (not shown) by bearing pin.The other end of hand brake lever 11 is provided with shift fork 11b, and shift fork 11b is hinged and connected by bolt 20 and outer casing seat 16.Outer casing seat 16 is tubular construction, is installed in the fixed jacket cylinder 4a end of Bidirectional self-regulating stroke boosting brake cylinder 4, with dismountable being threaded in fixed jacket cylinder 4a end.Be movably installed with on the mobile combined sleeve 4b of Bidirectional self-regulating stroke boosting brake cylinder 4 and push away iron ring 17, push away and be provided with a pair of lug 17a on the iron ring 17.The end of mobile combined sleeve 4b also is provided with spacing convex shoulder 4c, pushes away iron ring 17 between spacing convex shoulder 4c and outer casing seat 16.Shift fork 11b cooperates with a pair of lug 17a axial compression when rotating, its application force successively by push away iron ring 17, spacing convex shoulder 4c passes to mobile combined sleeve 4b, slide vertically thereby order about mobile combined sleeve 4b.
Side at outer casing seat 16 is provided with axial guidance 16a, is provided with axial channel 17b in a side that pushes away iron ring 17, and axial guidance 16a slides to set with axial channel 17b and cooperates, and is used for restriction and pushes away circumferential rotation of iron ring 17 works.
Be positioned at limit convex shoulder 4c arranged outside at mobile combined sleeve 4b sign bulge loop 4d is arranged, opposite side at outer casing seat 16 is provided with the intuitively scale mark post 16b of read-out mark bulge loop 4d axial location, and the convenient operation personnel understand the flexible situation of Bidirectional self-regulating stroke boosting brake cylinder 4.Certainly, by the axial guidance 16a also axial location of read-out mark bulge loop 4d directly perceived, so that operating personal is from different view.
Principle of work of the present invention is such:
When brake brake shoe 10 or wheel 12 abrasion, the gap that generally can cause braking between brake shoe 10 and the wheel 12 increases; When brake brake shoe 10 or wheel 12 renewed, reduced in the gap that generally can cause braking between brake shoe 10 and the wheel 12.This moment is long or shortening by the automatic accent of Bidirectional self-regulating stroke boosting brake cylinder 4, and can keep braking brake shoe 10 or wheel 12 are stablized within the limits prescribed.
When vehicle is implemented the wind braking, wind-force orders about mobile combined sleeve 4b generation longitudinal travel by other members of inside of Bidirectional self-regulating stroke boosting brake cylinder 4, and application force passed to rear brake lever 8 and front brake lever 2 successively, front brake lever 2 and the rear brake lever 8 front brake beams 1 of drive and rear brake beam 9 are in the chute 19 interior slips of truck side frame 18, and then drive brake shoe 10 and be adjacent to wheel 12, thereby realize car brakeing.
Implement when hand braking when vehicle, the car body hand brake device forces in the pin-and-hole 11a of hand brake lever 11 1 ends, utilizes crowbar principle that hand brake force is amplified.Bolt 20 rotations of the shift fork 11b of hand brake lever 11 other ends on outer casing seat 16, and stir and push away iron ring 17, push away iron ring 17 again with force transmission to spacing convex shoulder 4c, and then order about mobile combined sleeve 4b longitudinal travel occur, subsequent process and action are the same, seldom give unnecessary details.Operating personal can directly be observed by scale mark post 16b or axial guidance 16a the degree of displacement of sign bulge loop 4d.
