Embodiment
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing required in description of the prior art is briefly described.The utility model provides a kind of brake shoe of secondary braking
Iron, including：A pair of arc brake shoes main bodys 1, the pair of arc brake shoes main body can stop the pair of arc relatively
The mode of the axis folding of car shoes main body is set；A pair of sliding members 2, the set-up mode of any of which sliding component are：
One sliding component is arranged on the peripheral edge portion of an arc brake shoes main body, can be done with respect to the arc brake shoes main body
The mode of outer rim and slip laterally along the arc brake shoes main body is set, the sliding component and the arc brake hoof
The first reset components 3 are additionally provided between iron main body；A pair of friction facings, the pair of friction facing are separately positioned on described one
To the outside of sliding component 2, the longitudinally disposed outer surface of the friction facing is waveform, and multiple dissipate is set between wave
Hot hole 5, the friction plate transversely set multiple chip areas 6, be connected with some chip areas 6 for nail collection slot；Noise reduction layer, its
It is arranged between the sliding component 2 and friction facing, the noise reduction layer includes：First noise reduction layer, the second noise reduction layer and porous
Plate, the porous plate are clipped between first noise reduction layer and the second noise reduction layer, and first noise reduction layer and the second noise reduction layer are
Sound-absorbing rock wool material, the porous plate are metallic porous sheet, and thickness is 0.8~1.9mm, and aperture is 0.2~0.5mm；It is heat-insulated
Layer, it is arranged between the noise reduction layer and friction facing, and the thermal insulation layer is multiple with being set on the friction facing contact surface
Lug boss 7, the lug boss 7 are embedded in the shrinkage pool with being adapted on the friction facing with the lug boss.Described is secondary
In the brake shoes of braking, any one sliding component opens up a groove, and the peripheral edge portion of an arc brake shoes main body is located at
In the groove, the groove has the bottom of the arc along the peripheral edge portion extension of the arc brake shoes main body, the position of the sliding component
Width in the part in the outside of the groove gradually increases from one end of the sliding component to the other end, and the second reset components are located at should
Less one end of width of sliding component.In the brake shoes of described secondary braking, each arc brake shoes master
One end of body offers a positioning hole 4, and a positioning hole is opened in the less one end of sliding component width, another positioning
Hole is opened in the larger one end of sliding component width.In the brake shoes of described secondary braking, the sliding component width compared with
Distance of the small one end away from the positioning hole is 5~20mm.In the brake shoes of described secondary braking, the pair of arc is stopped
Fixing axle, described fixed a pair of arc brake shoes main bodys of axis connection, a pair of arcs are installed in the positioning hole of car shoes main body
The other end of brake shoes main body is connected with braking element and the second reset components.
In the utility model, when touching on the brake, in the presence of pole of braking, wheel cylinder promotes a pair of arcs to stop simultaneously
Opened outside car shoes, the inwall of fixed friction facing friction brake drum plays deceleration on the outside of sliding component or parking acts on.Work as car
When wheel does not stop operating completely, under the rubbing action of friction facing and brake rim, a pair of sliding members Outboard Sections width
Arcuately the brake outer rim of shoes main body of larger one end is slided to the less other end of width, and compresses the first spring to maximum
The rotation direction of deformation quantity, i.e. sliding component along wheel slides the distance that the first spring is compressed, due to sliding component outside portion
The width divided gradually increases from one end to the other end, therefore the width of whole brake shoes increases with the slip of sliding component
