Description
Technical field
The present invention relates to brake apparatus technical field, and in particular to a kind of floatation type brake pad.
Background technology
Bullet train mainly includes brake disc and brake pad with disc type brake structure, passes through brake disc and brake pad
Phase mutual friction, consumes moving vehicle or the kinetic energy of equipment, makes train stop motion.Brake pad generally use backboard and friction
The mode of block floating connection, i.e. brake pad have certain amount of floating relative to backboard, and brake pad angle can be with when brake lining is braked
Change, increase effective friction area between brake pad and brake disc, mitigate the eccentric wear of brake pad, improve damper brake
The service life of piece.
Chinese patent literature CN203146656U discloses a kind of floatation type brake pad, as shown in fig. 6, it includes：If
There are the brake pad backboard 102 and several friction members 103 of location hole 101, the friction member 103 includes friction portion 104, insertion
The location division 105 of the location hole 101 and the supporting part being arranged between the friction portion 104 and the location division 105
106, floatation type brake pad further includes clamp spring 107, is connected on the location division 105, the friction member 103 is had certain
It is connected on the brake pad backboard 102 amount of floating.
Above-mentioned brake pad has amount of floating relative to backboard, and solving cannot paste completely between existing brake pad and brake disc
Close, easily the problem of brake pad eccentric wear occur, and then improve the service life of brake pad.But due to the friction of brake pad
The difference of radius, will cause brake pad friction velocity of each point in friction inconsistent and forms moment of torsion, cause brake pad opposite
Rotated in backboard and then influence the braking effect of brake pad, closely arrange brake pad in order to avoid brake pad rotates generally use
Cloth, makes intermeshing mode between brake pad, but the close arrangement of brake pad can make the thermal diffusivity of brake pad be deteriorated, and need
Heat emission hole is molded on brake pad and realizes that brake pad radiates, but in sleety weather, due to accumulating in brake pad heat emission hole
Buffing be freezing together with sleet, form larger ice cube, seriously affect the braking effect of brake pad.
In order to solve the above-mentioned technical problem, Chinese patent literature CN103133579A discloses a kind of sleety weather and floats
Formula brake pad, as shown in fig. 7, it includes：Brake pad backboard 102, floating ground are connected on the brake pad backboard 102
Several friction members 103, anti-rotation structure, the anti-rotation structure are set in the gap between the friction member 103 of adjacent layer
For the anti-rotation rivet 201 being fixed by caulking on the brake pad backboard 102.
Although it is opposite similarly to solve brake pad without being molded heat emission hole on brake pad for above-mentioned floatation type brake pad
In backboard rotates the problem of, but anti-rotation structure is rigid structure, and when brake pad spinning force is excessive, anti-rotation rivet can be made
Its deformation effect braking effect, or even generation rivet is set to fracture and lose the problem of anti-rotation acts on into damage.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to ensure that brake pad has certain amount of floating, makes brake pad and system
Moving plate fitting it is even closer on the premise of, overcome existing floatation type brake pad brake pad spinning force it is excessive when, with
Rotation preventing device collision brake pad is caused to damage, or even rotation preventing device fracture lose antifriction cleaning block rotary action the problem of.So as to provide
A kind of floatation type brake pad, including：
Pad back plate；
Some brake pads, can floating ground be connected in the pad back plate, set between the adjacent brake pad free
Gap；
