Description
Technical field
The present invention relates to a kind of disk type braker, specifically, relate in particular to a kind of integral caliper air-pressure disc brake that has reference seat straight-line guidance mechanism.
Background technique
Have now and had multiple integral caliper formula break, most similar break all makes the braking surface of friction plate and the surface of braking object carry out friction catch by utilizing to applying certain pressure on the friction plate, is applied to frictional force and braking ability that pressure on the friction plate has just determined friction catch.And the pressure on the friction plate comprises vertical pressure and horizontal pressure, vertically pressure is by vertical or tangential linear distribution, laterally pressure is (with the distance dependent from the center of circle) that radially distributes, can produce heat during braking, when break during at heavy condition hot yielding capacity very high, the friction factor of friction material descends very big when temperature rise is very fast, and this is well-known heat fade.
And uneven pressure will cause friction plate to contact with braking the inhomogeneous of object, cause uneven heat flow to distribute, thus in braking process, some friction area material is not fully utilized and other region material is excessively utilized, excessively utilize the material of part will cause the localized heat decline, make friction plate all not carry out friction catch, reduced braking ability, and localized hyperthermia makes the life-span of friction plate significantly reduce with the braking object.
Realize stable and consistent pressure if can make friction plate, the total heat flow ability to bear that makes whole friction plate is reached maximum, can improve the braking ability of brake disc greatly, this shows, how to improve better and more stable braking ability, and can improve the life-span of friction plate simultaneously, will be an important development direction of break.Stable pressure means that stable energy transfer to brake disc, means that simultaneously stable heat is delivered on the brake disc; The conformity of pressure is meant the conformity under any pedaling force situation, not only just requires to keep stable in the time a certain section braking force, requires that pressure keeps stablizing in whole work period, just from minimum braking force to the highest braking force.
Disk type braker driving mechanism work commonly used has two kinds of pressure arm kinds of drive usually: (one) pressure arm fulcrum rotates around the center of circle and roll on supporting surface (move in the center of circle).(2) pressure arm on the sliding bearing of a low coefficient of friction or needle bearing around an immovable point roll (center of circle is motionless).
Mode one: the pressure arm fulcrum rotates around the center of circle and roll on supporting surface (move in the center of circle).
Referring to Fig. 6, when pressure arm was actuated by cylinder, it 1 turned to position 2 from the position.Rotate the circular arc center of circle and move to position O2 from position O1.Pressure arm promotes face center of arc and moves to B2 from B1.On behalf of reference seat, the vertical component of displacement move the direction that produces friction plate thrust, and finger pressure arm of force profile lifts here.But, on behalf of the needle thrust bearing on the reference seat, the horizontal component of displacement move towards the direction parallel with brake disc, this Horizontal displacement causes the beat (being the distance shown in the double-head arrow among Fig. 6) of reference seat, and reference seat the 4th part (seeing 5d in the Figure of abstract) is because the leading role of lining, this end cannot move to same direction, has just caused the reference seat beat in other words that tilts.When reference seat directly linked to each other with friction plate, the beat of reference seat can make friction plate produce beat, caused pressure to distribute along with pedaling force and revolute pair position constantly change and change.
Mode two: pressure arm on the sliding bearing of a low coefficient of friction or needle bearing around an immovable point roll (center of circle is motionless).
Referring to Fig. 7, the pressure arm rotating shaft is rigidly fixed on the caliper by pin, when pressure arm is actuated by cylinder, the center rotation around the shaft of rotational circle cambered surface, the pressure arm thrust face circular arc center of circle is when maximum travel position, and the center of circle can respectively produce a displacement in downward (generation braking force) and left and right directions simultaneously.Pressure arm 1 turns to position 2 from the position, it is constant to rotate circular arc home position O1, the thrust face circular arc center of circle heart moves to B2 from B1, and on behalf of reference seat, the vertical component of displacement (being 3.6mm among the figure) move the direction that produces friction plate thrust, and finger pressure arm of force profile lifts here.The horizontal component of displacement (being 0.9mm among the figure) represents needle thrust bearing towards the direction motion parallel with brake disc.When this motion is directly passed to reference seat, cause the reference seat beat in other words that tilts.When reference seat directly linked to each other with friction plate, the beat of reference seat can make friction plate produce beat, caused pressure to distribute along with pedaling force and revolute pair position constantly change and change.
Above-described two kinds of pressure arm kinds of drive, no matter whether the circular arc center of circle is rotated in the pressure arm rotating shaft fixing, because the structure that pressure arm is special: the special size design between two circular arc centers of circle, make the thrust circular arc center of circle generation level simultaneously with vertical displacement, this transmission of movement is given reference seat, produced beat when producing the braking impacting force, caused pressure skewness on the friction plate, pressure distributes along with pedaling force and revolute pair position constantly change and change.And the reference seat beat is considered to a kind of bad phenomenon, how to reduce or eliminates one of present just purpose of design of beat.
In existing break, usually only partly install a very short lining additional as guide mechanism at the 5d of reference seat, the guide bush of this weak point can not effectively be controlled waving of reference seat usually, leading role can not be provided effectively, and under limited spatial constraints, do not allow to install additional long bushing again, therefore can provide straight-line guidance to mechanism, be referred to as first guide mechanism and second guide mechanism by two short-range missiles that separate.
