Its advantages are simple structure, and high reliability.
Description
Technical field:
The invention belongs to the car brake technical field, is that a kind of plate disc brake with braking during standstill ejects and compensation mechanism.
Background technology:
In prior art, disclosed a kind of 95192863.5 patents, its structure is to combine by ejecting and compensate two parts, a slope member promptly is set on the brake axle axle sleeve, utilize the effect of the corresponding tabular ringwise adjustable slope member of spherical supports on the member of slope and spherical supports, withstand the piston axle and drive piston motion, so as to realizing the automatic compensation function in the braking during standstill process.The problem that exists is: because of its behavior of structure is limit, when braking during standstill, axle is in the state of moving axially all the time in piston, and therefore, axle easily produces end float misalignment, influences sealing effectiveness.And framing member is many in this mechanism, causes that the brake equipment volume is big, defectives such as complex structure, manufacturing process difficulty are big, manufacturing cost height.
Summary of the invention:
The objective of the invention is to design a kind of simple in structure, and can collect service brake, eject with automatic compensation function be that the plate disc brake of the band braking during standstill of one ejects and compensation mechanism.
For realizing that the technical scheme that purpose of the present invention adopts is: original automotive disc brake holding brake device is improved, has brake cylinder casing, piston is housed in the cylinder body, this piston has an osed top outer end wall, be provided with the brake surface that the braking jaw constitutes the clamping friction lining jointly with cylinder body, the principal character of this mechanism is: hydraulic braking and mechanical braking are located in the cylinder body, mechanical braking partly adopts leading screw, the rectangle nut, what elastic element was formed ejects and automatic compensating device, it has one and can rotate but cannot axially movable rotating shaft, the external part of rotating shaft is connected with outside brake pulling wire and realizes interlock, the end that rotating shaft is provided with leading screw stretches into cylinder body and internal piston, rotating shaft is provided with the axial location part, the leading screw part screws apart from the shape nut mutually with corresponding, the outside of rectangle nut is provided with elastic element, one end of rectangle nut is provided with the faying face that contacts with piston, bearing and elastic element are equipped with in rectangle nut outside, constitute a kind of plate disc brake with braking during standstill thus and eject and compensation mechanism.
The present invention ejects and compensation mechanism for the car brake technical field provides a kind of plate disc brake of desirable band braking during standstill, this kind mechanism is at normal driving glancing impact, oily push piston, the rectangle nut in the cylinder body advance simultaneously (stroke has only the gap between rectangle nut teeth and the screw rod teeth) realize braking.And when braking during standstill by the backguy rotating shaft, the conical suface combination that contacts with piston by the outside conical suface of rectangle nut, promote piston-advance, form and eject braking force automatically, when piston weares and teares because of brake facing, when needing the control position reach, the motionless rectangle nut of rotating shaft produces the rotation that is used to compensate automatically under the effect of spring, thereby guarantee that mechanism does not change the rotating shaft working condition, automatic compensation produces braking during standstill power.The leading screw that adopts, rectangle nut structure reduce the each several part part because of its structural simplification, and the production technology high conformity, and manufacturing cost is reduced, and product design improves.Owing to adopted the little composite material of coefficient of friction, reduced cost, and result of use is good, functional reliability is strong.Compared with prior art, have remarkable advantages such as simple in structure, easy to operate, cheap, that functional reliability is strong.
Description of drawings:
Fig. 1 is a general assembly structural representation of the present invention.
Specific embodiment:
Reach example in conjunction with the accompanying drawings and further specify specific embodiments of the present invention.
Referring to Fig. 1, the present invention includes: rotating shaft 1, dust ring 2, rotating shaft sealing circle 3, thrust baring 4, interior jump ring 5, conical spring 6, thrust baring 7, piston 8, rectangle nut 9, cylinder body 10, piston packing ring 11, piston dust ring 12, piston 8 is housed in the cylinder body 10, piston 8 has an osed top outer end wall 8-1, constitute the brake surface of clamping Friction disk jointly with the braking jaw 10-1 that is provided with on the cylinder body 10, this mechanism is provided with leading screw, the rectangle nut, what elastic element was formed ejects automatically, automatic compensating device, it has one and can rotate but cannot axially movable rotating shaft 1, the external part of rotating shaft 1 is connected with outside brake pulling wire and realizes interlock, axle 1 end that is provided with leading screw stretches in cylinder body 10 and the piston 8, the leading screw part screws apart from shape nut 9 mutually with corresponding, rectangle nut 9 adopts coefficient of friction to make less than 0.2 material, should be able to adopt engineering plastics to make, leave certain interval between the teeth of the rectangle line of leading screw part and the square thread teeth of rectangle nut 9, exist as the idle travel that does not influence service brake.Rectangle nut 9 exterior ends are provided with piston 8 contacted conical sufaces and combine, wherein, the axial location of rotating shaft 1 partly is set to thrust baring 4, rotating shaft 1 is adorned dust ring 2, rotating shaft sealing circle 3 with the contact position of cylinder body 10, piston 8 one ends are equipped with interior jump ring 5, conical spring 6 is contained between rectangle nut 9 and piston 8 inwalls, conical spring 6 one ends are stuck on the interior jump ring 5, the other end is stuck on the thrust baring 7, thrust baring 7 is contained on the rectangle nut 9 exterior platforms, and piston packing ring 11, piston dust ring 12 are housed respectively between piston 8 and the cylinder body 10.
Principle of work of the present invention is: rotating shaft 1 is owing to there are thrust baring 4 location, and when work, only by backguy (not shown) rotating shaft 1 and cylinder body 10, rotating shaft 1 can not be shifted.Rotating shaft 1 connects with piston 8 taper faying faces by rectangle nut 9, the rotating torque of rotating shaft 1 can be transformed into axial thrust and reach the braking during standstill effect.After the brake facing wearing and tearing, during service brake, piston 8 strokes are excessive, because hydraulic braking and mechanical braking are in a cover cylinder body 1, when inner chamber reaches in hydraulic coupling, piston 8 will move forward, rectangle nut 9 overcomes conical spring 6 under the pulling of rotating shaft 1 promotion will separate from conical suface, and there is not friction in faying face, and conical coil spring 6 pushes away 9 rotations of rectangle nut simultaneously, automatically produce stepless compensation because of the excessive gap that the brake facing abrasion is produced, reach automatic compensation function.Rotating shaft 1 apart from the shape screw thread with apart from shape nut 9 apart from the shape threaded shaft to leaving the gap, exist as the idle travel that does not influence service brake.
