Abstract
The invention relates to a self-energized brake, which comprises a bottom plate, wherein the bottom plate is provided with a leading brake shoe and a trailing brake shoe; the bottom plate between the upper ends of the leading brake shoe and the trailing brake shoe is provided with a supporting ejection block; the supporting ejection block is a supporting square block, and the section of the supporting square block is square; and the upper ends of the leading brake shoe and the trailing brake shoe have convex arc structures respectively, and the arc structures are in linear contact with the supporting square block. The self-energized brake has a simple structure; when the clearance between the upper ends or the lower ends of the leading brake shoe and the trailing brake shoe and a brake drum is changed due to the deviation of the distance between the axis of the supporting ejection block and the axis of the brake, because the leading brake shoe and the trailing brake shoe are in suspended states, the brake drum rotates to collide with the brake shoes to automatically realize adjustment in the upper and lower directions; and the brake has low temperature rise and good braking effect.
Description
Technical field
The present invention relates to a kind of self-energizing brake, specifically, relate to a kind of break that can regulate the braking gap between braking plate and the brake drum automatically, belong to field of mechanical technique.
Background technique
Like Fig. 1, shown in Figure 2, the self energizing effort drum brake is a kind of braking device that brakes to rotatablely moving, and the structure of self energizing effort drum brake generally comprises base plate 1; Base plate 1 is provided with two brake shoes, and two brake shoes comprise neck brake shoe 3 and from brake shoe 7, lead brake shoe 3 to be provided with neck shoe friction plate 12; Be provided with from shoe friction plate 13 from brake shoe 7, the top of base plate 1 is provided with supports jacking block 6, and this supports jacking block for supporting bearing pin; Lead brake shoe 3, between brake shoe 7 and support bearing pin, be respectively equipped with return spring 15; After removing return spring 15 and cover plate 16, can see the cross section of supporting bearing pin, neck brake shoe 3 and be respectively equipped with the arc structure 4 of indent from the upper end of brake shoe 7 for circular; The arc structure 4 of two indents cooperates with the support bearing pin; Be provided with brake pump 5 at base plate 1 center upside, neck brake shoe 3 and hinged, its end that suspends from the lower end of brake shoe 7; Be that rounded end is realized resetting through the collision that brake shoe deadweight and brake drum rotate brake shoe, but can only adjust by left and right sides both direction like this.
In the structure of break, the required distance between supporting pin axis and the brake backing plate axis is very strict, and in a single day deviation appears in the distance between its axis; Will cause neck brake shoe 3 and change from the upper end of brake shoe 7 or the gap between lower end and the brake drum; Owing to support that bearing pin defines neck brake shoe 3 through arc structure 4 and, can't adjust and lead brake shoe 3 and from the position of brake shoe both direction about in the of 7, like this from the position of brake shoe both direction 7 about; Neck brake shoe 3, upper end or the lower end little from gap between brake shoe 7 and the brake drum can produce friction always; Cause dawdling of friction pair, loss power causes the wheel hub temperature too high.
For fear of dawdling and the wheel hub heating; Usually need high-ranking military officer's brake shoe 3, transfer from the gap between brake shoe 7 and the brake drum greatly; Up to leading brake shoe 3, not producing the phenomenon of dawdling from brake shoe 7 and brake drum; Because the defective on the existing brake structural, can only be through transferring big neck brake shoe 3, come the gap of both direction up and down of adjustment indirectly from the gap of left and right sides both direction between brake shoe 7 and the brake drum, be that the center is when adjusting to support bearing pin; Will cause the brake clearance of two breaks of left and right vehicle wheel inconsistent, can take back or take over during brake.
Summary of the invention
The problem that the present invention will solve is to above problem, provide a kind of simple in structure, can adjust brake shoe upper-lower position, the self-energizing brake that braking effect is good automatically.
For addressing the above problem, the technological scheme that the present invention adopted is: a kind of self-energizing brake comprises base plate; Base plate is provided with neck brake shoe and from brake shoe; Be provided with the support jacking block on the neck brake shoe and from the base plate between the brake shoe upper end, it is characterized in that: said this support jacking block is for supporting square, and the cross section of supporting square is square; Neck brake shoe and be respectively the arcuate structure of evagination from the upper end of brake shoe, this arcuate structure contacts with support square line.
Further improvement as technique scheme:
Said neck brake shoe and be provided with brake pump between the brake shoe.
Said neck brake shoe and be provided with return spring between the brake shoe.
The lower end of said neck brake shoe and be provided with the adjustment spring between the lower end of brake shoe, neck brake shoe and be provided with left and right sides slack adjuster between the lower end of brake shoe.
Said left and right sides slack adjuster comprises regulator, regulator the neck brake shoe the underpart and between the underpart of brake shoe, regulator respectively with the neck brake shoe, hinged from brake shoe, the outer peripheral surface of regulator is provided with thumb wheel.
Said thumb wheel is connected with automatic control tegulatingdevice.
Said automatic control tegulatingdevice comprises runner and plectrum, runner be fixedly connected from brake shoe, plectrum with hinged from brake shoe.
Said plectrum is provided with attachment hole, and runner is provided with backguy, and an end of backguy is connected with attachment hole, and the other end of backguy is fixedly connected with base plate.
One end of said adjustment spring is connected with the neck brake shoe, and the other end of adjustment spring is connected with the attachment hole on the plectrum.
The radius of said arcuate structure is 100-300mm.
The present invention takes above technological scheme; Have the following advantages: support jacking block and be set to support square, the cross section of supporting square is square, simultaneously high-ranking military officer's brake shoe and be set to the arcuate structure of evagination from the upper end of brake shoe respectively; This arcuate structure and neck brake shoe and from brake shoe respectively line contact; Simple in structure, with distance between the break axis deviation appears when supporting the jacking block axis, and cause and lead brake shoe and from the upper end of brake shoe or the gap between lower end and the brake drum when changing; Be in state of suspension because of the neck brake shoe with from brake shoe; Come to realize the adjustment of both direction up and down automatically that temperature rise is low through the collision of brake drum rotation to brake shoe, braking effect is good.
