Abstract
The utility model provides a clearance automatic compensation mechanism for the friction plates of a wet-type multi-plate brake. The clearance automatic compensation mechanism comprises a brake piston, a pressure plate, a pressing sleeve screw, an elastic pin bush, a brake housing, a semi-axial housing, the friction plates, a cushion plate, stators, and the like, wherein, the piston is mounted inthe brake housing; the elastic pin bush is mounted in the pressure plate and is in tight fit with the inner hole of the pressure plate; the pressing sleeve screw penetrating the elastic pin bush is connected to the brake housing; the friction plates and the stators are mounted between the pressure plate and the cushion plate sequentially in an alternate manner; the brake piston drives the pressureplate, so that the stators compress the friction plates tightly, and frictional resisting moment brake wheels is generated; when the friction plates are worn out, the pressure plate driven by the piston overcomes the friction force of the elastic pin bush, and moves forward continuously, so as to compensate clearance between the friction plates; when brake is removed, the pin bush and the pressure plate cannot slide relative to each other, and the clearance when the friction plates are used in the beginning is still kept. Therefore, the utility model ensures that the brake travel is kept still, solves the lag-brake problem caused by common-structure friction plates which cannot be adjusted in time after being worn out, and improves the reliability of a wet-type multi-plate brake.
Description
(1) technical field
The utility model belongs to Vehicle Engineering vehicle bridge field, relates to a kind of wet multi-disc brake strip clearance automatic compensation mechanism.
(2) background technique
In recent years, along with the continuous development that braking ability is required very strict engineering construction machinery, wet multi-disc brake obtains application more and more widely.Wet multi-disc brake is broadly divided into the plain edition wet multi-disc brake, wet multi-disc decompression break, multifunctional wet multi-disc brake etc. according to installation and working principle.Which kind of break no matter, if because of friction plate heavy wear, the thickness attenuation, the capital increases brake clearance and influences braking effect, in case because the friction plate replacing is untimely, braking failure occurs, just can't realize braking function, bring threat for the safety traffic of vehicle.Therefore, how adjusting the friction plate gap, make it gap requirement up to specification, is the problem that any braking model all wants emphasis to consider and solve.
Vehicle bridge technical field at home at present, the friction plate gap compensation of wet braking roughly has two kinds of forms: a kind of is to adopt to add the form of adjusting pad, promptly after the friction plate of break uses a period of time, measure the gap after wearing and tearing when taking maintenance apart, increase the adjustment pad according to wear extent and come the compensate for wear amount, this mode maintenance operation complexity, efficient is low, and labor intensity is big.Mode is adjusted in another kind of brake bush gap, adopt and adjust the nut adjustment, on the adjustment nut, be processed with gear, mesh with mating pinion, by turning the screw on the small gear, screw pair thereby drive the screw thread of adjusting on the nut, by the wear extent of spiral motion friction compensation sheet, though it is more convenient that this kind adjustment mode is operated, but still need regularly by artificial adjustment.
(3) model utility content
The purpose of this utility model is to provide a kind of functional reliability good, and cost is lower, use easy to maintenance, the wet multi-disc brake strip clearance automatic compensation mechanism that can improve engineering machinery braking reliability.
The technical solution of the utility model is: wet multi-disc brake strip clearance automatic compensation mechanism comprises brake plunger 1, platen 2, gland screw 3, elasticity guide 4, brake casing 5, semiaxis housing 6, friction plate 7, disc 8, stator 9.It is characterized in that: piston 1 is contained in the brake casing 5, and sealing forms the braking oil pocket by O type circle; Three elasticity guide 4 uniform being loaded in the platen 2, with platen 2 endoporus drive fits, gland screw 3 passes elasticity guide 4 and is connected on the brake casing 5; Friction plate 7 and stator 9 are alternate successively to be contained between platen 2 and the disc 8, and disc 8 is pressed on the interior edge face of semiaxis housing 6 by friction plate 7 and stator 9.They all are positioned in the break inner chamber of semiaxis housing 6 and brake casing 5 formation.
The beneficial effect that the utility model can reach:
The ingenious elasticity guide that is loaded in the platen that utilized of the technical program, under the effect of piston thrust, platen and guide can slide relative.Behind friction disc wear, under the situation that the gap is strengthened, platen is under piston promotes, overcome the frictional force of elasticity guide, move forward, friction compensation sheet gap is when the brake off platen resets, spacing by elasticity guide left end, thereby guarantee that each braking distance is constant, the motor reaction time is consistent with new friction plate, overcome the ordinary construction friction disc wear after, the braking maneuver that untimely adjustment brought lags behind, even the unsafe factor that braking failure brought.Improved the reliability of wet multi-disc brake.
(4) description of drawings
Fig. 1 is the utility model wet multi-disc brake strip clearance automatic compensation structural scheme of mechanism.
(5) embodiment:
As shown in Figure 1: wet multi-disc brake strip clearance automatic compensation mechanism comprises: brake plunger 1, platen 2, gland screw 3, elasticity guide 4, brake casing 5, semiaxis housing 6, friction plate 7, disc 8, stator 9.Piston 1 is contained in the brake casing 5, forms the braking oil pocket by the O RunddichtringO; Three elasticity guide 4 uniform being loaded in the platen 2, with platen 2 endoporus drive fits, gland screw 3 passes elasticity guide 4 and is connected on the brake casing 5; Friction plate 7 and stator 9 are alternate successively to be contained between platen 2 and the disc 8, and disc 8 is pressed on the interior edge face of semiaxis housing 6 by friction plate 7 and stator 9.
Brake plunger 1 makes stator 9 and friction plate 7 compress generation frictional force thereby promote platen 2 under the effect of pressure oil, and the frictional resistance moment that this frictional force forms makes wheel braking; Under new friction plate use condition, leave the gap between elasticity guide 4 right-hand members and the gland screw 3, gap length equates with the piston deceleration stroke.When friction plate 7 uses a period of time to wear and tear, gap between the friction plate 7 is strengthened, at this moment brake plunger 1 promotion platen 2 moves right, when elasticity guide 4 run into gland screw 3 end faces spacing after, platen 2 is under the powerful thrust of brake plunger 1, can overcome and elasticity guide 4 between frictional force continue to move right, up to the friction plate group is pressed on semiaxis housing 6 interior edge faces, make wheel braking.When removing service brake, platen 2 with elasticity guide 4 under the effect of Returnning spring, to left movement, elasticity guide 4 left sides are run into brake casing 5 end faces and are spacing, because the elastic force of Returnning spring is less than the frictional force between elasticity guide 4 and the platen 2, when brake off, can slide relative between elasticity guide 4 and the platen 2, the gap when still keeping new friction plate between elasticity guide 4 and the gland screw 3.Thereby guarantee that each braking distance is constant, the motor reaction time is consistent during with new friction plate, overcome the ordinary construction friction disc wear after, the braking maneuver that untimely adjustment brought lags behind, even the unsafe factor that braking failure brought, improved the reliability of wet multi-disc brake.
